XMP causes Boot Loop

[Zeragonii]

Hi folks, my first time posting here so apologies for any poor formatting, etc.. 

 

Cutting a long story short, I've had my Ryzen 3900X build running solid for over 2 years, and recently (After installing and playing the Battlefield 2042 demo which did NOT play nice with my rig) my RAM began acting up more than it origninally did. Now when I try to turn the XMP Profile on I get stuck in a bootloop that does not end (Left running overnight to see if it might pull through, no luck.)

 

I can provide more in-depth specs of my RAM if needed, but my mobo is an MSI x570 MEG ACE and has been rock solid since I built the machine. My RAM of choice is the Corsair Dominator Platinum RGB (32GB - 4x8GB) and it was a pain in the neck to get stable when I first built the machine, but now it's appeared to have deteriorated.

 

Did I lose the silicon lottery or am I doing something wrong? I've been debating ordering some Samsung B-Die modules and tweaking them to optimal levels but if the cost can be avoided then I'd honestly rather that.

 

Thanks for any input you guys have, its appreciated.

What did you do that made it "a pain in the neck to get stable?" Were you just running XMP or did you modify the timings/speed beyond that?

Tuning the CPU to play nicely with XMP was interesting before the AGESA updates came out. Those specific issues dissipated over time, but Zen2 has always been a bit of a nightmare for me getting it stable.

 

But to answer your question, I was just trying to get XMP to work outright, system was having none of it until I tuned all the voltages for the CPU to match the video that LTT Anthony did on the lineup. Always figured XMP would just work stock because it has for me in the past, evidently not.

Then my guess would be that the memory controller on the CPU has started to degrade, not the memory itself. The memory is designed to run at those speeds, timings, and voltages - it was binned to work with those settings before it was sold.

 

How eXtreme of a memory profile are we talking here? Zen 2 generally couldn't do over 3800.

This happens if your ram is over 3600, some CPUS like mine handle even 4200Mhz ram 2100mhz IF clock.
Try setting it 3600mhz

I'm running my memory at 3600MHz, with CL 18-19-19-39. Or well, I -was-.

Could it really be the memory controller on the CPU? I was of the impression that they didnt exactly degrade outside the bounds of typical CPU degradation, so perhaps I'm wrong?

Motherboard is running on the latest BIOS version?

Yessir, to my knowledge.

For just 3600MHz, I'm not so sure. Zen 2 was usually able to hit those speeds without a problem. So perhaps the RAM itself had problems running at XMP speeds from the start - maybe it wasn't binned correctly - and the RAM is what has degraded over time.

 

Are you able to make 3600MHz work with looser timings?

I havent tried that tbh, though I'm willing to give it a shot.

So the thing is that RAM like 3600mhz CL18 isn't good at all. It would make more sense to buy a 4000Mhz CL19 kit and then lower the clock speed and the CL, for example Patriot Viper.

How @YoungBlade said, it could be wrongly binned, maybe your RAM is worse than 3600Mhz CL18.

 

You could Increase the SOC voltage to 1.1v and see if it works, if not, set 1.4v on the RAM if it's lower than 1.4v
You can also lower the clock speed to 3200Mhz, if this is stable then it means that the RAM isn't binned correctly aka refund it get something else.
If it doesn't run 3200Mhz then your memory controller is either bad or damaged.

 

For instance, I was lucky and mine runs 4200Mhz Ram and 2100mhz IF clock at CL17. My RAM is G.Skill Trident Z Royal Silver 4400mhz CL17

 

I would get some 3600Mhz CL16 even if they are lil more expensive, or a 4000mhz CL19 and set it to 3600mhz, leaving stock CL and then tinker a little and lower the CL or rise the clock, or both (but not both at the same time.

I have my eyes set on a set of B-Die 3200 CL14's that I'll likely try to clock up to 3788MHz CL16. If that isn't stable then I'll refund the kit and assume my Memory controller is taking an L

So I shoved the memory in, tried running it at a conservative setup of 3600 CL16 but it wouldnt post. Think my CPU might be the one to have taken the L and it might have been goosed from the start, maybe I just got super unlucky in the silicon lottery? Either way I'm stumped to troubleshoot further, and quite disheartened by the fact that I might need to replace a £480 CPU...

Lower it to 3200Mhz, if it doesn't work then, send the CPU back.
