Re: Threadripper 2990WX Crashes / Instability

Your temp goes up to 67.5? That’s very interesting because that’s the temp that mines goes up to.  Which means that the bigger size of your radiator vs my smaller size doesn’t matter since we both have the same temps.   That temp is not the greatest because the cpu will throttle and slow down at 68 degrees to keep it from overheating.  Other people on this forum with different coolers only go up to 50c while using all the cores for example so it shows that our coolers are just not as good.

Re: Threadripper 2990WX Crashes / Instability

Hello op, me and a friend of mine have the same problem you were experiencing. Doing random stuff like not installing CAM or removing and plugging the memory sticks worked for you, correct? You haven't experienced the problem since your last post half an year ago?

Re: Threadripper 2990WX Crashes / Instability

Here's my experience on how I fixed the issue in my own case. First of all, I believe that the computer was crashing because of the heat. But I noticed that my CPU temp was only 62 degrees or less whenever it crashed. What I noticed was that 99% use of my RAM was causing trouble.  I use 64GB ram, so when I removed my 4 sticks of RAM it worked longer but still crashed my system somehow.

My PSU is fine

GPU is fine

BIOS is updated

All drivers updated

So I decided to lower my RAM (64gb) speed from 3200mhz to 2133mhz. Also, I changed my DRAM voltage from 'Auto' to '1.210V'. Lastly, I switched off 'Core boost performance'. After switching off 'Core boost performance' my 2990wx won't cross 3GHZ. Before it would jump from 3GHz to 4.2GHz automatically from time to time...

I strongly believe it is a RAM issue, and it was drawing too much power which in turn n was overheating the mobo. So I changed my DRAM voltage to 1.210V (before it was on auto) and set my frequency to 2133MHZ.

Also, its summer here. So once winter will come I will definitely increase my RAM frequency and Core speed.

So far I've done too many stress tests and it hasn't crashed once!!

Re: Threadripper 2990WX Crashes / Instability

Coincidentally, I have the exact same problem with this chip.  There might be a flaw in the design of the 2990WX series.  My 2990WX crashes with PRIME 95 benchmark, and FREEZES randomly under Windows.  From the PRIME 95 benchmark, it points to a defective core that is causing Windows to freeze.  Even as doing a fresh installation of Windows can easily cause it to freeze on you half way through installation.  Currently waiting for AMD to replace it under Warranty, but haven't heard back from them yet.

Re: Threadripper 2990WX Crashes / Instability

JC6180, I suspect you do not have the same issue.  With no information on your system, I cannot really tell.  I suggest you open a new thread and post all your relevant information.  I also suspect you have not uprooted a design problem but it is possible you have a bad chip.  My MB had a problem causing memory errors, but not an AMD problem.  My 2990WX always ran great - never crashing except for the memory errors in the Event Viewer.  Thanks,  John.
