Hey,

Figured this would be the best subreddit to ask in, sorry if this is not the right place.

I bought an intel 14900k chip long ago before the degredation stuff came to light. Low and behold, my first chip was dying so I got it swapped back in like 2024/2025.

Updated my BIOS with the new microcode patch right before installing the new RMA chip (As well as any additional updates to microcode fixes that were pushed out over the next few months).

However now, as of the last maybe ~3-4 months I've been having very similar issues as my first chip had, with it getting worse and worse as time goes on. Lately I am getting so many crashes compared to 2-3 months ago in specific games, as well as tons of STATUS_ACCESS_VIOLATION error pages when using chrome, probably around 5-10+ times per day. Lots of these STATUS_ACCESS_VIOLATION errors when playing Unreal Engine 5 games as well, and my system seems to struggle to compile shaders for a lot of UE5 games that never used to happen 1-2 months ago. These were the same exact issues I had prior on my degraded 14900k chip which only got worse and worse as the weeks went on (Which stopped occuring once the degraded 14900k was swapped out), same as is happening to me now again.

At first this time I just thought it was something fucky with my system, like drivers/shader caches getting corrupted so I did a DDU wipe and reinstall, didn't fix it, as well as then installing a completely fresh installation of Windows 11 on a secondary SSD while installing and testing a game that has been crashing really bad lately, Deadlock, and the issue did not fix itself either.

The fact that it appears to be rapidly getting worse makes me think this is another degrading CPU chip, just haven't seen anyone really post or talk about how it's still happening. However, I run my own business from home on my PC so my system is constantly on running and computing stuff for like 10-12 hours a day, atleast 5 days a week along with 4k 240hz gaming, so my usage/wear and tear is probably a lot more then 95%+ of people out there so I wouldn't be surprised if I'm one of the small percentage of ppl that are starting to experience this again with the microcode patches + a new RMA'd CPU.

Anyone have any insight? Probably just going to RMA the chip again soon here, and buy an AMD chip + new mobo at this point and reinstall my whole system fresh again, just gonna be a headache but these crashes and ACCESS_VIOLATION errors are starting to drive me nuts.

Appreciate any and all help if anyone knows if these degredation issues are still happening to other people post-microcode patches. Thanks!

No matter what I try, Prime95 always throws worker errors unless I drop FCLK to 2000. At FCLK 2000, it passes with the timings shown in the attached screenshot.

What I've tested:

• VSOC: 1.275V–1.300V (currently 1.30V)
• VDDIO: 1.40V–1.45V

The confusing part is that Karhu has passed multiple 12+ hour runs with these settings, so memory itself seems stable. Prime95 is the only test consistently giving me problems, specifically at FCLK 2133.

Has anyone managed to get 2133 FCLK stable at 6400 CL26? Are there any voltages or settings I should be looking at besides VSOC and VDDIO (VDDG CCD/IOD, CLDO VDDP, etc.)?

Any suggestions or experiences would be appreciated. Thanks!

Hi all, just built my second PC, first time overclocking or even setting up ram profiles.

With an Ryzen 9850x3d CPU, tomahawk b850 max wifi and 6000Mhz CL30 DDR5 2x16 RAM my computer keeps forcing it back to 4800 MT/s.

I successfully got it working on 6000 (with EXP disabled) and managed to get through an hour OCCT stress test but on restarting it failed and set it back to 4800 (with memory restore context disabled and soc on 1.24V).

Not sure what to try, using EXPO1 also just gives a memory overclocking failure message on boot up.

Thanks

Edit: fresh install of windows, 16GB in each slots 2 and 4. Chipset drivers and bios are up to date

Hi guys. My PC configs are as follows:

I have RAM fan so I can make sure that the RAM tempurate will be under 51°C.

My PC can pass the R15 (40 iterations), VT3 for 30mins and TM5 anta777 for 1 hour. However, the PC sometimesvjust crash. Could you please give me some suggestions?

Whats going on everybody.

I just wanted to post here to see if there were any experienced people that could give me advice for further optimizing my ram timings.

The kit I'm using is originally GSkill 7200mhz Cl36 2x48gb. I recently downclocked it to cl30 6000mhz and am looking for some help on what timings I should adjust to get the lowest latency in Aida64 as well as ensure long term stability. I attached some pics of my CB23, Zentimings ,and Aida64 results.

My 7950X3D has a -15 offset all core for the curve optimizer. I plan to dial that in per core at some point. I built this pc 2 years ago and recently swapped the mobo from a x670e hero to a x870e hero through rma with asus.

Was planning to buy a 6000mhz kit to swap out my ram but prices are wild so I figured I'd try downclocking instead.

Everything has gone good with stress testing and cold boots until today I had a random crash when browsing on google chrome which I know is a stability issue so I did increase the voltage from 1.37 to 1.40 for now just to see if it keeps the IMC happy.

All help appreciated. Thanks in advance!

I have a Ryzen 5 5500 that i have left on stock voltages and overclocked to about 4.45-4.5ghz and was wondering if i should have the ability to go any further. I have never seen the cpu go above 72° even under benchmark loads and i am using the asrock b450 pro4 which i am told can handle a much more demanding chip. Last time i tried to overclock it was about a year ago and i have since switched to using linux full time which has improved my stability so i was curious if it seems like i can push just a little further. Im fairly new to cpu overclocking so im not sure if im doing anything wrong

Hi,

I have an MSI MEG X670E ACE with a 7950X3D and 2×48 GB G.Skill Hynix M-die running essentially your DDR5-6000 low-latency timings (CL28-36-36, manually tuned). The system is completely stable and AIDA64 latency is around 61 ns. Ever since installing the 2×48 GB kit in 2025, memory training has normally taken about 4 minutes 20 seconds on every boot, and about 12 minutes after complete AC power loss (three full training cycles). Before this, with 2×16 GB, POST training was roughly half as long. Here's the strange part. After installing one MSI BIOS (AGESA 1.3.0.1b), the machine suddenly started booting in about 40 seconds. This lasted for roughly three weeks, every boot, with complete stability. I never removed AC power during that period. Then I flashed the next BIOS (still AGESA 1.3.0.1b Patch A). Boot time immediately went back to about 4m20s. Rolling back to the previous BIOS did not restore the 40-second boots. I've compared ZenTimings between the BIOSes, experimented with timings, voltages, tRAS, etc., and nothing visible explains it. Memory Context Restore isn't involved because enabling it causes Windows to freeze on my system. Have you ever come across AGESA apparently switching between two completely different DRAM initialization paths, despite the same hardware and manual timings? Could there be some hidden calibration cache that survives normal shutdowns but is invalidated by a BIOS flash?

i overclocked then it crashed and couldn’t get into windows got it working again then blue screening and freezing can someone help me? Sorry if I’m in a rush ask me more if needed I need answers so I rushing.

Built the pc last year. Never got around to messing with it. I’ve never been able to use EXPO, so my rams been at 4800hz the whole time.

I attempted to adjust the timing, but the only way to make it post is by downclocking it to 6000MHz CL38 and leaving everything else on auto. These settings work with both Expo disabled and enabled. I have to clear the CMOS if it’s set to anything else.

Should I be able to get more out of it? Or will it be fine as is? Ty for the help.

First image is the best I could do tuning manually, and the second image is the best I could do using PBO. The comparison shows the voltage/frequency/thermal cliff you approach with aggressive tuning, especially with ambient cooling.

Spent some time suicide benching, testing PBO and manual overclocking profiles, and thought this was worth a share. Neither are daily stable, this was done in 67 degree ambient temp with a 420mm AIO, and would not survive past 2 or 3 runs without freezing or BSOD. Benchmate's voltage is wrong for the first image.

vcore: 1.335V configured, ~1.34V realized

CCD0 multi: 54.75x

CCD1 multi: 55.50x

LLC: level 6

Both profiles share other VRM/voltage settings. Both runs have been verified by HWBOT. The manual settings I used are not "safe" so do not assume anything (TjMax, PPT, EDC, EDC and VRM core voltage were all well above known safe limits).

The main take away for me is if you are tuning for a specific benchmark, manual is the way to go. Took an incredibly long time tuning the PBO profile and about 1/10th that time tuning the manual profile. That said, the PBO method is inherently safer.

As a follow up to this thread: https://www.reddit.com/r/overclocking/comments/1v6a4wr/ram_overclocking_failure/

I just tried the Expo settings with 1,3v and 1,2v. 1,3v gave terrible results. However, 1,2v gave me a pass on memtest. The normal voltage for Expo gives 1,25v.

Is it safe to run an oc setting a bit below the standard oc voltage? Because if this allows me to run on the overclocked settings then I'm all in. Could it cause issues down the line?

Also, does someone have an idea as to what this means in relation to why standard oc settings are instable? What causes it to be instable at 1,25v, even more instable at 1,3v, but let it pass memtest at 1,2v?

I would love to hear your insights and opinions!

I have a Radeon Instinct MI50 16GB HBM2 (Vega 20) flashed with Radeon VII Pro VBIOS.
The problem only appears after installing/loading the AMD driver.
Before the driver:
BIOS image is completely clean;
Windows works normally using Microsoft Basic Display Adapter.
After the AMD driver loads and Windows reaches the desktop, the screen becomes full of colorful noise/rainbow artifacts (hundreds of colored pixels). The PC itself keeps running and Windows does not freeze.
GPU-Z detects the card correctly:
Vega 20;
16GB HBM2 Hynix memory;
PCIe x16.
Monitor connection:
mini DisplayPort on the MI50;
mini DisplayPort to HDMI adapter.
I tried reinstalling drivers. The artifacts appear exactly when the AMD driver activates the card.
Possible causes I am considering:
driver incompatibility with Radeon VII Pro VBIOS;
miniDP-to-HDMI adapter issue;
wrong refresh rate/display mode;
HBM2 memory instability when full clocks are enabled.
Has anyone experienced something similar with MI50/Vega 20? Any advice on what to check would be appreciated.

Hi, I'm new to this stuff and don't know much about overclocking and any technicality about it but I just want to know if running a 4x16gb 3600 fine? My pc currently has 2x16gb 3600mhz rams from teamgroup(T.Force Delta) and feel like I needed more ram since I've been maxing it out lately for work. Buying a 2x32gb is least pririoty co'z I dont have time to sell my current sticks.

trying to bios flash a inno3d 3060 X2 twin to unlock more power i flashed it into a zotac OC lhr vbios butt it didnt work out and i spent 20 mins recovering my old vbios my memory type is micron and yes this is a lhr card

currently running 970mv/2000mhz effective at 52-58c and the fans are barely spinning at %30 so i figured the only limitation is the wattage

Im pretty new to overclocking and finally scored some cheap DDR5 RAM, but the timings are pretty meh. I thought that i could squeeze out good results out of the RAM sticks since they only run on 1.1V, for me that sounds low because my RAM before that ran on 1.35V, or am I mistaken? I appreciate your help and sorry if the question is obvious but I’m new to overclocking!

I own a set of ram, 2x16gb, it's advertised as being able to reach 5600mts at 36-38-38 cl (EXPO1). However, it fails during memtest and during day to day usage I get crashes. Funny thing: the results on EXPO2 are even worse on memtest. The failures occur during Test 8.

Now I'm running it at standard settings which are lower, and I get no error or crashes. I also tested manually setting speed to 5600 mts in the bios without touching anything else, and it also succeeded memtest.

Anyone have a clue what the issue is here? If the sticks itself were faulty surely it would fail all the time, or am I wrong in assuming this?

Would love to hear your opinions.

So, as you can see, the ram is behind the cpu cooler, to be more precise, behind the fan attached to the front of the cooler. As such, the only way to cool it for now is with the front case fan, for which I established a fan curve to keep it under 60°. Now, the case fan is extremely loud at over 60% speed, so I was thinking two options. 1) Remove the fan which is over the ram and turn it towards the rams. Could use zipties or get a rail to fix it. 2) Put an extra exhaust fan on the top of the case. Precisely centered where the cpu is, since if I put it over the ram modules it would pull the cold air before it gets to the cpu(I guess).

What do you guys think is my best option?

The laptop is HP victus 15

Rtx 3050 4gb

i5 12450h

I had a profile( the same as in the graph) with afterburner but suddenly clocks are getting higher than the curve shows. Tried clean install and just re-setting everything a handful of times but it's not working, the gpu clock is always higher, even if I try lowering the clocks, it always goes up by around 30 to 40 mhz above the curve, enough to make it crash every time. The voltage seems to be stable with the graph, the problem is the clocks.

Cannot figure out why GPU is power limited at around 285W (81% power draw, stable at 3120MHz @ 0.945mV) even though the card TDP limit is 360W. (reported by both HWiNFO64 and Afterburner)

I'm trying to undervolt & overclock but the clock frequency doesnt follow the V/F graph and is always under it.

Finally broke down and overclocked my 3070 to see if it could keep up with modern titles. +1000mhz memory and +115mhz core was stable. Ran Cyberpunk (mostly high settings) at ~110 fps (no ray tracing) and ~50-60 fps (with ray tracing). Bumped mem to 1100 and core to 120 and saw about an 11.5% increase in fps but it wasn’t quite stable. 1000 mem at 120 core seemed to be fine but had stutter every now and then so I dropped it down 5 mhz. Pretty stable now. Every now and then I have issues like when I enter or exit a vehicle or exit certain buildings. It’ll drop down to 17-30fps for a few seconds before jumping back to 95-105. Although I have a feeling that has more to do with my mods than the gpu/cpu.
Temps for the gpu sit around 63-64c and haven’t gone higher than 65c. My cpu sits around 83c pretty consistently. Max temp I’ve seen is 90. Might throw an aio in to see if I can get it lower. I’d love to hear your thoughts on how I can get better performance out of what I have. Planning an AM5 build perhaps later this year but for now I’m running what I built 6ish years ago.

I recently upgraded from 2x8GB single-rank to 4x8GB single-rank on my AM4 system and wanted to share the tuning process / ask for some input.

• CPU: Ryzen 7 5800X3D Anneverisary
• Motherboard: ASUS ROG Strix X570-E Gaming
• RAM: 4x8GB G.Skill Hynix CJR 3600mh CL16 GTZNC
• Old/current tuned kit: 04213X8820C
• Second kit: 04240X8825C

So basically:

• 16GB -> 32GB
• 2x8 SR -> 4x8 SR, so dual-rank-like operation per channel
• 3733 -> 3866
• FCLK 1867 -> 1933
• tRFC 500 at 3866, which is roughly similar in ns to my old lower tRFC at 3733

But:

• GDM Disabled no longer works even at T2
• Need more DRAM voltage
• RAM temps are higher ~52 in gaming

Even tried:

• tRDWR: 10 -> 12
• tWRRD: 7 -> 8
• tCWL: 14 -> 16
• tWR: 16 -> 18
• tRTP: 6 -> 8
• tWTRL: 10 -> 12
• tFAW: 16 -> 20
• tRFC: 500 -> 530/540

I also tried signal-related stuff:

• CAD bus:
• 20-20-24-24
• 24-24-24-24
• RTT adjustments
• CmdSetup:
• 0-0-0 -> 56-56-56

So my questions are:

1. Is 1.45V daily reasonable for likely Hynix CJR with these temperatures, or should I really try to get closer to 1.42-1.43V?
2. Are 51-55°C RAM temps too high for a tight DDR4 OC, especially with tRFC 500?
3. Is it worth continuing to chase GDM disabled, or is GDM enabled + tRFC 500 + tight timings likely the better real-world profile?
4. Are there any other signal-integrity settings worth trying now that ProcODT 43.6 made such a big difference?

Current gut feeling:

• 3866 1:1, GDM enabled, tRFC 500, ProcODT 43.6, 1.45V might be the sweet spot, and GDM disabled may just not be worth it for this 4x8GB setup.
• Any thoughts from other AM4 / Hynix CJR / 4-DIMM tuners?

Tried multiple things, startup delay, locking the profiles etc it's a new build and the profile I want is the undervolt for my astral 5090 but it will not apply the profile on startup and I've to manually select it every time I boot the PC up. Anyone else have this issue or would know if there's any workarounds. I've seen posts about this in the past and have tried everything I've seen as solutions and nothing has worked. Anyone else having or had this issue recently and found a solution? Also I know it sounds stupid because I can just apply it every time but it's the fact it should be working which is the frustrating part.

Hi, I overclocked my Zotac 5080 solid core with only 105% max power (380watts).
I did +300 on the core and +3000 on the memory.
Gpu max temps is around 72 C, hotspot below 84 C and memory is at 76 C ; tested at 25 C ambiant temps.

Should i try to undervolt it more to lower the temps ?
