What’s the cooler? 5900xt will need a better cooler under load than the 5600 as you said it reached 98°C.
Now first test stability of stock CPU and XMP for the ram.
Prime95 small FFT and OCCT for CPU. If it doesn’t shut off for 30-40mins in each, then it’s stable enough.
Memtest and Testmem5 with Aanta absolut config for RAM stability test. Let it complete several cycles.
After both are stable at stock, proceed with PBO. Only make small change at once and run the CPU tools above to test PBO after each change. Revert if not stable. Repeat until the best settings are attained.
Keep hwinfo open while running these tests to monitor the temps. Ideally 85°C would be the max I’d allow for my CPU, if it’s going higher at stock without PBO, get a better cooler/undervolt. If its going higher with PBO or OC, revert it.
Cinebench passing isn’t enough for stability check. Its for a quick benchmark score.
Im using Artctic Freezer 34 Esports duo
My case is a low end Ant Esports ICE 112
Yeah I did the stock CPU and XMP on @ 3200MHz and ran the multi core test on Cinebench and the system is stable right now
I did memtest a few months ago and the RAM is stable
Did all the tests lasted like 4 hours I think
Thanks for the detailed info man
I will check out Prime95 and OCCT thanks
I’m going out in a few days and can’t risk CPU shutting it down but will do all these tests once Im back home
Should I do these tests soon considering I just got the CPU today from Elitehubs in case of faulty CPU
Or I would need to raise this to AMD anyway considering the package was sealed and they can’t do anything about it?
PBO increases power draw from like ~142W to ~230W on 5900XT. Not worth it for the performance increase IMO. And while your current cooler can handle it at stock, it’s probably going to be overwhelmed with PBO on.
Have you updated your BIOS to the latest version? Do the crashes happen only when stress testing or does it also happen when its idling or under low-moderate loads?
IIRC PBO when set to “Auto’“ usually defaults to the motherboard limits. This refers to the max current and power values the motherboard manufacturer has determined that the board can handle. It won’t damage the board but it’s not going to factor in your cooling and it won’t be an “efficient” overclock.
Okay so
BIOS is latest.
RAM used to work fine with 5600x and passed memtest before.
PBO is now off.
Crashes have happened while stress testing as well as more moderate loads.
Can you try reseating the CPU? Inspect the pins and socket to see if everything looks fine. When installing the heatsink, don’t over tighten or unequally tighten the screws.
I suppose you won’t have any grounding wrist strap, so be barefoot, touching the concrete ground. It’s better than nothing. So you don’t kill the sensitive stuff with electrostatic discharge.
As a precaution, I have removed the cmos battery for few minutes (took the opportunity to replace it with new ) and then manually install latest bios using bios switch. This will reset any configuration stored by motherboard for previous setup.
RAM is the first thing I look at for instability as well. Give a quick clean up and make sure the sit properly.
Cleaning motherboard from any residue from previous configuration is the next thing to look at.
If the four sticks were not in a single kit (i.e bought as individual sticks or as kits of two), they’re not 100% guaranteed to be stable at xmp when together. 4 sticks can be heavy for the CPU’s memory controller, especially if they’re dual rank.
So test the sticks in pairs of 2 at XMP. Or even individually.
If its stable, the CPU is alright. After that, in order to run all 4 sticks, there are two options:
Run at very low speed where its mostly going to be stable like the current 2400mhz.
Manually dial in the xmp rated speed, voltage and latencies and test stability. And if unstable, reduce the speed by one step. Basically trying to reach the closest point below xmp where all 4 sticks are stable.
