When doing my new build I will be testing to verify this. Right now cant be asked to take pc apart again.

Just reporting back that since the PSU switch over have not had any issues :). Matter of fact I think my system as a whole is more stable, not experiencing the sometimes rare random issues I used to. Thanks again for all the suggestions. Gonna see if I can RMA my evga PSU and sell it later.

The new PSU has a native 12vhpwr port so using the included 12vhpwr cable that came with the new psu. I cba to test again at this point. Additionally my cablemod cable was nowhere near as loose as that adaptor in that gif you linked, also had the glass side panel pushing up against it slightly...

Installed it yesterday, just had a 2 hour session no issues. So I think as you all were saying the PSU was the issue.

Just bit the bullet and purchased a MSI MEG Ai1300P, should be arriving this evening...

I assume these spikes did not appear in the log?, because i'm not seeing anything above around 400w. Just was playing for around 20 mins, Path tracing enabled, 100% power limit and powered off. Ok, reading this it makes sense...

Downloaded the new patch played for a while, decided to test Path Tracing to see if it had improved after a few mins powered off (I only play with standard RT usually), gpu-z log showing 322w when it went off. The only difference is this time I had a 70% power limit in place (as the perf is the...

Just stopped playing after around 50mins of normal gameplay driving around ncpd missions different areas of the map, one story mission and no OCP yet. Too tired to play any longer so will update this thread once I've had more 2hr+ sessions playing the game. I will say at default settings having...

I got a day off work and was getting ready to potentially pull the trigger on a MSI MEG Ai1300P. But thought let me see if I can find the wattage at where the trip occurs as suggested by Dan_D. So I started running benches at 5k then 8k (DLSS balanced/perf) but noticed vram kept getting filled...

I only play with vsync + gsync and when possible frame gen enabled.

Well during a 30 min play session in CP2077 today with everything set to default, no OC it powered off... I am running a cablemod 12v-hpwr to x4 8-pin cable, this one: https://store.cablemod.com/product/cablemod-e-series-pro-modmesh-sleeved-12vhpwr-pci-e-cable-for-evga-g7-g6-g5-g3-g2-p2-t2/...

Apparently I don't have permission to read that post, lol.

I will leave my pc unplugged tonight to check cmos battery. I've set everything to default. The PSU was purchased in 2019, so not that old. Also a question can a spike still occur if gpu is power limited via afterburner? as in my card has been limited to 350w up until this point, so can the 4090...

Well completely disconnected any icue controllers, plugged all fans into mobo headers and still randomly powers off while playing CP2077. Today I disabled XMP left PBO and GPU OC enabled have just been playing CP2077 for 3 hours with no issue. I have the Team Group 8Pack Edition 32GB (2x16GB)...

I thought updating icue solved it got through 7 runs of the benchmark at 8k, then on the 8th it powered off. Edit: after uninstalling icue ran multiple cp2077 benchmarks in succession at different resolutions, temps were warmer as fans were just at low speed, but no random shutdowns... Before I...

I just ran a few benchmarks in succession, then upped the render res to 5431x3055 that bench went through fine. Then upped it to 7680x4320 and powered off just as the bench was about to start so it does seem to point to OCP tripping, but this still occurs even when I've power limited my card to...

Meshify C x2 corsair LL 140mm front intake x1 120mm noctua bottom intake x2 120mm corsair LL top exhaust (aio rad) x1 120mm corsair LL rear exhaust Have all fans connected to corsair commander pro with icue controlling fan speeds.

Yeah going to leave the longer stability test running next week whilst i'm at work.

GDM disabled with [email protected] = bsod, with 56 it boots but errors in test GDM disabled [email protected] = boot without 56 but errors, latency was around 58.5ns So sticking with GDM enabled, plus tRDWR 9 is stable :) Here is a comparison of a game benchmark (which seems to be very memory sensitive)...

I would run it at 1.55v but this ram does not have any thermal probes (as far as I am aware) so I don't know what the temps are.

In terms of the voltages suggested as I mentioned earlier I cannot get exact values, what I enter in my bios is not what Zentimings reports the voltage is, for example VSOC in bios 901 = 0.902v or 900 = 0897v in zentimings, so the voltages in the screenshot is the closest I could get to intended...

Cheers, will give this a shot tomorrow and post my results.

Was expecting a better latency result tbh. (135 processes in task manager when bench was run):

Tried loosening timings based on guide and what you suggested but it after a few faliures it was voltage that was the issue, 1.51v passed: Going to see if I can now tighten any further.

1. Anything beyond FCLK 1900 results in WHEA errors, even tried 1.55v but really don't wanna drive more than 1.5v daily. 2. Thanks for link 3. I don't mind 1.5v, my case has fairly good ventilation (x2 140mm intake, x1 120mm intake, x3 120mm exhaust (240mm aio) in a meishfy c.

The settings you suggested did stabilize tCL 14 much further into the test, but still errors out: Here's stable results from someone else with the same kit with a 5800x + x570 mobo, but they are not stable on my setup: I will try reverting back to my previous tCL and voltages and try SCL 4...

I am well aware the gains to be had will be small with 5800x3d but I am looking to get the timings as tight as possible. I have been looking online and Zen Ram OC leaderboards spreadsheet and can see some awesome results with various dual rank b-die 32gb kits but I do not seem able to get stable...

Thank you for all your help and suggestions!, I actually learned quite a bit.

Ok made those changes and SCL to 4 and all is stable. Did not make a difference to latency result but overall still a nice improvement.

I could tighten a bit further in some areas, but I don't think it would make much difference:

I will give this a shot later this evening, thanks.

Ok after painful amount of boot failures and my mobo not being able to see my boot drive unless I turned the psu off and back on again I found anything above 3600 is not bootable. I then resorted to the ryzen dram calculator to get some safe timings for 3600. With these timings I get a latency...

Based on your recommendations this is what I was able to achieve: I was unable to disable geardown mode, using 2T or 1T with AddrCmdSetup 56 I get BSOD at desktop. Still after running latency test lowest result I get is 73.7ns

Unfortunately it's not Samsung B Die, I believe they are Hynix CJR: Also 408 was too tight, got crashes in gaming after a few hours, 410 seems to be the limit at stock voltage settings.

Thanks for the tips, I managed to tighten the timings more with your advice but latency result is still 73.7ns. For some reason even though I set tRTP to 7 it just sets it to 8, no idea why. I think I can set it to 6 and that sticks. If I lower the tRFC any lower than 408 I get BSOD.

I have a Gigabyte Aorus Master x570 (F34 Bios), 3800x in PBO mode and 32GB of Corsair CMT32GX4M4C3200C16 (4x8gb) ram. I only use this pc for gaming at 1440p@120hz / 4K@60hz, so did not see the benefit in going to 3600mhz with looser timings. I have been tightening the timing of the ram at...
