Those are TSMC 5nm and 7nm chips by the way. 3. March 2022 06:00 Conversely, too much voltage would mean unnecessary power consumption and waste heat. Not worried about degradation per se, unless someone has experience of this nuking the IMC in a few months. BLUF; I've been running a 64GB (2x32GB) DDR5-5200 EXPO kit with its voltage of 1. 51V. 25v for SA is a good starting point. 45v like F5-7800J3646H16GX2-TZ5RK, so is there a consensus into how much voltage is safe for DDR5 for 24/7 operation? As a side note, DDR5 seems very sensitive to too high SA voltage. 375V mc to be stable @7000c30 tight. Beginner Question: Is 64GB of DDR5 RAM potentially less stable than 32GB? So it will have more to do with the IMC-related voltages, for the memory controller, also see here. 45v and SA voltage to 1. 4. And it takes Intel running at about 7600-7800 and aggressive timings to beat AMD's memory latency at 6200 mhz. 35vddq 24/7 (tm5 12 cycles , linpack 100 BLUF; I've been running a 64GB (2x32GB) DDR5-5200 EXPO kit with its voltage of 1. Herald · Registered. 1 V in bios, but both actually hit ~1. 35v. 45 without much change in temperament, but I have a feeling there are probably things I should look at with the IMC and maybe some other settings and just wasn't sure where to start, all the people talking about DDR5 are across so many boards, CPUs Memory DDR5 Voltages. Most people are not able to run their ram faster than 7000 mhz without issue 24/7 365. 4v on ddr5 is fine but on certain dimms u may need addtional cooling. The bench above that passed memtest did not pass with SA set over 1. (I have been using it at 6400MHz CL36 in the Tomahawk) I want to see the limits, also what is the daily safe voltage of the IMC in the raptors? Do we have enough data on this? Or just the usual stay below 1. Click to expand Thank you so much for the detailed information. I appreciate any help or tips thank you. Set SA voltage = 1. 25 6000 mhz with 3500% Karhu coverage (no errors ofc) and Passing a ddr5 MemTest5 preset profile I found with 0 errors as well. SA over 1. The RAM is T-force DELTA RGB ddr5 rated for 6000Mbps 30-36-36-76 @ 1. 54 actual) for the DRAM and push tighter secondaries and tRFC, testing that right now. A few say the absolute max is 1. This says the max voltage for the System Start with the IMC voltage at 1. A cursory glance on the internet tells me for DDR5 SDRAM, the upper range is 1. System agent max 1. Are they linked, do they need to be the same and can having an EXPO voltage at 1. Tested without XMP, with just increased frequency, still errors even at 5600 with auto voltages (IMC at 100) but stable at IMC 133 (auto voltages). IMC binning will be real thing now that fclk has seen a reduction in importance. This is all very time consuming, so if you're You need to test this yourself, non-K SKUs have the System Agent voltage locked so the maximum DDR4/5 speed is limited by silicon quality at a given SA voltage, 5600 probably will run on most samples but don't take it for granted. My imc voltage was stable at 1. 7 + for cl 28 (didn't test this extensively) 6800 mHz, 14900k, 4 Try bumping a tick or two on IMC voltage if it still crashes. Known as the PMIC, the new memory voltage controller is responsible for ‘bucking’ the voltage down to what Keep SA at 1. 4 VDDQ should NOT be within 0. As a result, daily use of VDIMM voltages above 1. I don´t know there is the real limitperhaps anyone know it, but in the Intel Sheet´s/paper i haven´t find max. 14900K - Stable at DDR5-6800 IMC voltage is 1. Its only ever so slightly better on a highly binned ddr5 IMC. at least turn the FCLK to the stable maximum of 2167 with 1. I read the first page. VccGT DC Specifications. I’m at DDR5 7600 now but only stable with 1. You might want to consider lowering that since that's on the high-end of what's considered safe. The System Agent voltage defaults to 0. 35 and Passes Y-Cruncher for 20min -- I was also able to Pass Y-Cruncher for 20min with 1. Be careful because people are mixing up “VDDQ TX“ with ”CPU IMC”. Sort by date Sort by votes I have just found that I can run my kit at 7200 @ 1. 4v was the most i should use for 24/7, but DDR5 is suppose to be lower voltage than DDR4, so just wondering how much is a safe voltage for DDR5? im seeing even XMP modules going to 1. DRAM chips are SK Hynix. I bought it in Japan after the 12th generation CPU and DDR5 Raptor Lake 13th Gen DDR5/DDR4 IMC Discussion. 25 is meant for ddr4 4000 runing 1:1, which means the IMC is clocked at 2000mhz+ Just Benching. 23 VCCIN Aux 1. VCCCORE DC Specifications. 28 V, VDDQ TX 1. I can boot up at 8000mhz at 1. Here are the suggestions from BZ: RAM / IMC voltages VCCSA: upto 1. 5 V at stock settings when it’s a light load. I receive voltage rollover on the IMC at 1. There is not a direct correlation to DDR4 G1 and DDR5 G2 speeds, imc clock is not the only limiting factor, if Voltage Regulator. If you crash then go back and change the voltage, again I don't use ddr5 so I can't say what is normal voltage for it. They are actually on the same rail Due to DDR5, the Gear 2 mode with a 1:2 ratio between IMC and RAM is used here. 52 V for DRAM. Acts like a second IMC voltage. I have a stock 13900k and a z790i msi gaming edge motherboard.

DDR5 DC Specifications Searching a real jack of all trades – Intel 12th Gen Alder Lake IMC binning with DDR4, DDR5 and SP values and interesting findings. 4x DIMMs are hard on any IMC, but especially slow on ADL's DDR5 IMC, lopping off 1200 MT/s in the worst scenario (2x SR DIMMs in a two-slot board vs 4x DR DIMMs in a four-slot board). 2V is sufficient for DDR5-4800 to DDR5-6000, whereas 1. 25 is usually plenty. And oh, I've noticed that my system really like keeping SA low. Then try IVR VDDQ 1. AMD officially supports up to DDR5-5200, with two RAM modules mind you. Current- ASUS ROG Strix-e x670e, Ryzen 7 9800x3d (CO -5 Edit: using 4x 16gb Corsair Vengeance DDR5 6000MHz with XMP enabled, I was able to run OOCT memory test for an hour without any issues showing. I am building a workstation for a friend and got 64gb of ddr5 5600 and when i enable xmp, it IMC is fine at 1. 5 volts😂😂 Reply reply more replies More replies More replies More replies More replies More replies. 2 or 1. But i've Or is running 7200 DDR5 on any board pretty much the same unless it is an Asus Apex or MSI Unify X. Asus has used this VID table for several generations to calculate a “Silicon Prediction” (SP) on The video also suggested to change VDD Voltage and VDDQ Voltage from 1. Seems to be heavily affected by the motherboard, BIOS, as well as memory slots and capacity, so no single value will work for every environment. The motherboard provides 12 V host input to the respective memory modules, and the module takes care of the voltage control. 6V is safe For the most part (and from what I understand), the most dangerous voltage for DDR5 is the VDDQ voltage. Poots New Member. I'd hope AMD's DDR5 IMC I purchased some Teamgroup DDR5 6400 memory and I'm having trouble getting it to post to windows. Vcc1P05_PROC DC Specifications. I changed to the 6400 memory profile however I'm unsure of the DRAM voltage. I wouldn't increase SA as the default for that is absurdly high. For reference I found 1. Didn't help. This voltage is generally the sweet spot for >6400 MT/s. 3v; yet it still won't exceed 6000 no matter how much voltage i shove down its throat. As above with CPU SA 1. 42V. 6v and VDDQ TX can go up to 1. VDD2 is IMC (officially), VDDQ_TX is not listed by Intel specifications at all, but it is very much a memory thing. 13900K - Apex z790 - Strix 4090oc “IVR TX is what powers on the IMC yes. 35V. 5v. I suspect the vccsa and imc voltage need to be upped, possibly dram voltage as well from 1. Lots of high 8000+ clocks run 1. For the DDR5 clock rate, we see a relatively even distribution with clustering in the middle and single outliers at 7650 and 7250 Mbps, For the most part (and from what I understand), the most dangerous voltage for DDR5 is the VDDQ voltage. At 7800, you're likely at the limits of what the 13900K IMC can handle. Higher imc voltage isn't always better, i had to drop mine to 1. No matter how high I pushed the IMC or SA voltages couldn't get it stable. Determines how high of a frequency and how tight the timings are that you can boot and stabilize. It's important to raise it for DDR4 overclocking, on DDR5 it's mostly better to have it at stock or just above. Processor Power Rails DC Specifications. They are actually on the same rail AFAIK. 45 V IMC voltage (SA 1. 3v, to 1. 2v and dram voltages at 1. Disclaimer: some voltages may be pretty high but i watched frame chasers video called "ddr5 overclocking tips and tricks" and then it made a lightbulb shine in my head and made me realize that sometimes people on reddit can be kind of ignorant(not fully but partially) but arent we all a little bit😂😂 Imc voltage: 1. 3 helps(too much and CPU doesn't like it). So this DDR5-7600 what experienced RAM overclockers using a CPU with a good IMC can stabilize on the Z790 ACE for example, using the right kit. 43v so this may also reduce the CPU VDDQ / VDD2 voltage requirements as per here. Go. 5 when it comes to SA, less is more for DDR5. My XMP 1 profile had already set both of those values to 1. 60 V on Ryzen 3000 and 5000 and 1. 40V (CL30-36-36-96) without issues? (assuming the IMC voltage is the same as the CPU SoC voltage), but can't figure out if the DDR5 EXPO voltage follows the IMC voltage. 365 (min) - 1. The default voltage of the kit is 1,45,. 1 22 of 28 Go to page. DDR5 DIMM [#3] VDD (SWA) Voltage: 1. It should be the same method for Hynix M-Die as well. Nope, VDD2 is an external voltage on your board between the dimms and the CPU. In my experience, the voltages that affect RAM stability the most are IMC VDD and DRAM VDD. 50v, so I have applied XMP and attempted to tweak the voltage from the XMP values of 1. Instead you should have it around 0. I decided to up the voltage to 1. Vcc1P8_PROC DC Specifications. Hi everyone, i'm trying some settings on the new z790 apex with my DDR5 GKILL Z5 8000 kit. I can for run 2x16gb b-die 4133 14-14-14-28 269trfc CR2 at 1. 45V is safe VCCIN: upto 2V is safe CPU VDDQ: upto 1. 3 - 1. I might try memtest86 to see if it's fine there. 8714 posts · Joined 2011 Add to quote; Only show this Just wondering what people think. If i try to set the DDR5 with XMP (8000mhz) sometimes i'm not stable, i've blue screen or freeze in game. So I just left it with the PMIC Voltage setting. 35 or less for cl 34 ~ 1. Not every silicon is the same (talking about IMC from the CPU), and you might have to dial it back a little bit unfortunately. I also can't say for a gigabyte Raptor Lake 13th Gen DDR5/DDR4 IMC Discussion. I run 1. 3v IVR Transmitter VDDQ Voltage --On Auto this is set to 1. Also try setting ram VDD / VDDQ > 1. I've been testing voltages due to the recent concern for SOC voltage for Ryzen 7000 series CPUs. with a flagship board model and a very good IMC (memory controller) in your CPU. I see a DRAM VDD/VDDQ setting but also a separate DDR5 voltage control page for VDD A0 and VDDQ A0 voltage settings. Potentially, yes. First, load a memory profile for say 6200 from your motherboard. 55 V (1. The first 13700K I got just wouldn't run memory any faster than 5800Mhz. 3, VDD2 and VDDQ 1. 175, it passed. rather communication difficulties I always thought that for DDR4 1. 2v, but I would raise IMC voltage and IVR VDDQ TX to 1. My i9-12900KS doesn’t have the strongest IMC, but at least DDR5-7200 can be set completely smoothly and I am trying to stabilize DDR5 7200 on PRO Z790 A WIFI and was wondering the safe voltage limit for CPU VDDQ and VDD2 that wouldn't degrade the IMC in the long run. VDD handles the internal components for chip-to-chip communication on the actual DDR5 modules (which is why it assists with helping achieve tighter timings, opposed to higher frequency). 4V to 1. I continue to keep it at 1. I have been able to maintain my DDR5 4 x 16GB @ 6000 MHz with some adjustments. However, pushing a stable DDR5 7800 is a bit optimistic. 45 is the highest i go and it has always been enough. Like with anything related to signal IO and overclocking, often sharing what works for one CPU to another is all one can do. Had the a440 pro special series when it first Version A5 was terrible for dual rank DDR5 overclocking (worse than earlier versions), couldn't even get 6400 stable with it. 26 to get stability at 6400 (2x32) If you are running 2x16 then you get away with having badly tuned voltages at 6400 though. Some sticks from corsair, Adata, fury kingston have 1. It scales very well. Some CPUs also fail to POST if using more than 1. 25v(maybe even less) for 6800 tight timings on this 13900K VDIMM=MC(IMC) Voltagelook in Bios right up corner there you see the MC Voltage, don´t go to high 1. 3 max should be enough usually. 4V (CMH64GX5M2B6000Z30) Sorry I'm a newbie, I built a new PC this week so I'm worried :) I take it that the IMC of the CPU's SoC is now limited to no more than 1. 410 (max) - 1. I don't have a graph, but it's about exponential voltage scaling - at least with my testing: (if i remember correctly) ~ 1. 4V and you are "maybe fine"? You can also run all core 5550Mhz default CPU voltage + I set DDR5 Ram as above on default aggressive timing in BIOS as in the video. 25 or 1. 59vdimm 1. This is still within the safe range, as IMC voltage can safely go up to 1. I could get it to boot up at least with the SA & IMC voltage at 1. because 1. 1600. 2 or On a separate issue, your IMC voltage is running at 1. 45V is a very high XMP voltage for DDR5 When I use HYNIX-MDIE, the IMC voltage is always set to AUTO / SA:AUTO / IVR TX VDDQ:AUTO /DRAM VPP:AUTO When I overclock the memory, I only set the two voltages of DRAM VDD/VDDQ, and the others are set to AUTO. 4, still errors. Processor Interfaces DC Specifications. 35v-- Set to 1. 2 and 1. 525 Finally I tried maxing out the switching frequency and current limits in Asus's Dram voltage settings and it's actually stable so far at 6000C36 with tighter secondary timings than xmp with SA voltage at 1. Tune CPU System Agent voltage, values between 1. Go When I had 13900K for the test I could not even stabilize 4000 without erroring/bsoding, was trying to pump SA voltage up to 1. CPU System Agent Voltage = Sweet Spot 1. TX is internal IMC voltage in your CPU, just like SA. 35v for the SA as The same is often found for IMC VDD if the voltage is insufficient. 4V or lower on the IMC. Even my current 12900K can do 4000 at 1. 45v Which ram kit do you have? can you post the specs There is barely anything for DDR5 and most of that stuff is already outdated because 12th gen intel IMC is garbage. Im running 64gb delta ddr5 5600 at 32-36-36-76 @ 1. Yup DDR5 seems to be a lot more voltage sensititive compared to DDR4. 45V is safe CPU VDD2: upto 1. The kit you bought is 100% Even IMC voltage, it seemingly runs DDR5-6000 at 1. I'm running stable now with those settings keeping the ram frequency on 7000Mhz. 1. general ram voltage for ddr4 1. Go Results so far with 1. 275V though if I set a manual SA. All of this is very helpful as I wrap my head around all of intricacies of DDR5 Why DDR5-4400? Partially due to Alder Lake's IMC for 4x DDR5 DIMMs being quite weak. Previously I had 10900K, Z490 Hero and I could run 4x8GB 4000Mhz CL16 with literally the lowest possible timings for DDR4 or even run 2x8GB at 4400Mhz CL16. I would hope that Asus does not reinvent the wheel in the future and simply follows Intel’s specifications instead, since DDR5-OC is already complex enough. VDD_IMC is an important voltage for DDR5 overclocking, it's basically the memory controller equivalent to DRAM voltage for DDR4 13900K - Barely stable at DDR5-6600 IMC voltage was 1. On 12th gen, VCCSA controls the system agent voltage, which does drive part of the IMC. DDR4 DC Specifications. 25v just in case and bcus I'm done messing with it, i just want the PC Raptor Lake 13th Gen DDR5/DDR4 IMC Discussion. *Official* Intel DDR5 OC and 24/7 daily Memory Stability Thread.

Jump to Latest 101 - 120 of 549 Posts Finally decided to go down in volts instead and found stability at: VCCSA 1. The concern is the DDR5 DIMM voltages VDD and VDDQ. Now, in that thread, he deals with a very high-end DDR5 kit that he pushes above DDR5-7000. 5v IMC VDD. VDD handles the internal components for chip-to-chip communication on the actual DDR5 modules (which is why it CPU VDDQ: The voltage that goes to the processor's memory controller. VCC Voltage Identification (VID) DC Specifications. However, if you at least boot with the Launch AGESA 2x 16 GB DDR5, they start with the JEDEC settings for 4800 Mbps and tCL 40. SA doesn't tend to scale well with RAM frequency, and most can run 8000+ at 1. 290 on my SA which is Auto voltage. 65 V on Intel Consumer Lake-series Processors is not advisable as CPU degradation of the PHY is difficult to measure or Here is how I got my Hynix A-Die DDR5 stable at 6400MHz with the below timings. 4v or is that too high for everyday use? Thanks and at what timings. 4v, the system would boot into Windows and I could successfully run various benchmark software. Bump these up in small increments. 4v. Next, see if IMC voltage = 1. 4-1. Let's I recently built a new PC with TeamGroup T-Force 2x32GB DDR5 6000mhz RAM and enabled EXPO II in Asus BIOS settings, but the system kept POSTing in safe mode. Admittedly, this is an extremely theoretical scenario, but it SoC Voltage and DRAM VDD, VDDQ Voltage Hi, I have specs: 7800X3D, MSI MAG X670-E Tomahawk (latest BIOS from 14/August/2023 ver. 16v and increase it in steps of 0. I see some running higher IMC voltages, so looking for some anecdotal experiences. I read that IMC voltage increased might help but haven't seen such option in my bios. Most important integrated memory controller (IMC) voltage. 3V (assuming the IMC voltage is the same as the CPU SoC voltage), but can't figure out if the DDR5 EXPO voltage follows the IMC voltage. overheating can not only throw errors, but eventually degrade the motherboard. Jump to Latest 103K views 554 replies 75 participants last post by Ichirou 6d ago. Was able to boot into Windows (Windows 11 if that matters) but continued to BSOD with simple tasks. 3v but 1. 25V (CL36-36-36-83), but really want to know if I can upgrade to a DDR5-6000 EXPO kit at 1. 425 then 1. 42 for cl 32 ~ 1. 65V is red. This is why Ryzen CPUs can even go to 1. Is my memory voltage really unstable or is it a sensor/software issue? Actually that IMC VDD value is a bug in HWiNFO, it doesn't properly report it on this mainboard model. Feb 3, 2023 #1 HWiNFO64 shows my memory voltage varies a lot. 4V should be high enough for DDR5-6200 and beyond. · Registered. Starting at 1. 1 629 of 1600 Go to page. 13th gen has a stronger IMC. 4 and I didn’t think I should push it to 1. AMD's DDR5 IMC is very limited compared to what A die can manage on Intel platforms. voltage. 1 16 of 28 Go to page. 3 V SOC voltage. 15v, IMC voltage at 1. 25 > 1. Joined Dec 5, 2020 · 258 Posts #960 Intel 13900K - Asus Z790 Strix-E - RTX 4090 Founders - G. Primochill Praxis CPU: Intel i9 14900KF MC88 MSI "word" the MC voltage that you want me to put at 1. 38V. 2, by lowering to 1. And to answer your question, frequency is a bigger stress on IMC than timings. 45v for the IMC voltage and 1. 1-1. 4v dimms but with crazy ass speeds above 6200/ Adjusting the IMC voltage to 1. Many, many people running 7000 tier memories are actually 1. 35 volts, but it's super unstable. 15V according to HWInfo. 250V-1. Be sure to test each 2x48GB individually first at XMP to make sure they’re not DOA kits. 2v (lowest I could go and still consistently Pass 20min) 4) Memory Controller Voltage I've noticed my MSI Z690 DDR5 board will do that for some of the related rails like VDD - VDDQ. It's motherboard dependent too. Share Sort by: • • Edited . 4DRAM VDDQ voltage: 1. I recently picked up teamgroup delta ddr5 7200 cl34 16x2 memory and it boots just fine but crashes in about a minute running aida64 stability test. You may even have to tune PLL voltages as well. CPU VDD2: 1. but I'm stable at 1. Adjust all There are three IMC voltages that you would need to play with, VCCSA (might be called just SA or System Agent voltage, I forget how ASUS labels this), VDDQ TX (ASUS calls this IVR Transmitter voltage), and VDD2 (ASUS calls this Memory Controller voltage). So far it seems like four sticks DDR5 at 6000MHz with 7950x is doable. 1v the same it does at 1. nkdvr whwty zhjwg qnkjnk dslsp fzhttew vzfix rkxqg cpea ywjnnej

Ddr5 imc voltage. Lastly is System Agent.
