[SOLVED] Threadripper 2990WX and MSI X399 seems to be underperforming? Help!

Hi all. I'm the proud owner of a new build with a Threadripper 2990WX, MSI X399 Creation, 64GB DDR4 3200, Enermax TR4 360 Liquid Cooler and RTX 2080 with a Corsair 1200W PSU.

It's replacing a 4 year old i7 as a rendering workstation. During my research even the stock setup seemed to be scoring in to the high 5000s with Cinebench and 33 - 36 seconds with the Corona Renderer benchmark tool.

I'm struggling to get anywhere near those and I can't work out why? I'm new to overclocking and the only way I seem to have any stability is using the Game Boost feature.

I can't find any guides for manual overclocking with the BIOS version I'm using so not all of the settings seem to match.

The Cinebench scores I'm getting fluctuate hugely but average around the 2900 mark. I randomly hit over 5000 once but can't get close to that now. My Corona Renderer times have all been over a minute. Corona is my renderer of choice so as I see it I'm missing out on almost twice the rendering speed I was expecting.

To add to the mix I only get 48GB of my 64GB showing as available even though in BIOS I can see all 4 sticks and it knows they're all 16GB. I've since taken two sticks out so have 32GB currently. I tried swapping them around and reseating but to no avail.

So where should I start? The stock scores I've seen reported elsewhere are significantly higher than what I'm getting. CPU temps are well within range so cooling seems to be ok.

Should I use game boost or manually overclock? If so, what voltage and multiplier am I best to use for my setup? Is there anything else I need to look at?

I have the option of Precision Boost Overdrive (which is currently enabled) but is this designed to be used in conjunction with or instead of regular overclocking?

Sorry for all the questions but as you may have guessed I'm a bit stuck! Any help or suggestions of what else to try would be much appreciated.

I had similar issues when testing our 2990WX on an MSI X399 board, also. Not impressed with MSI support - even reached out via email and the response was 'we don't have any motherboards to send you', when the question was 'I am having issues with even minor overclocking stability on this hardware, with this XYZ BIOS version, and the the LED code being provided isn't listed with any error codes...can you help'.

Ended up just going with a Gigabyte Aorus board.

Might also try the ASRock TaiChi boards...I got the 2990WX up to 4.2 GHz on that one...almost had 4.3 stable.

Your RAM is not compatible with your motherboard. You can start from here. I just search your mobo and that Corsair is not listed as compatible with your motherboard and processor. That i think is your problem. I think is instable at 3200Mhz and you loose performance. My RAM are not compatible with my mobo too. But I succeed to go for 2800Mhz (3000Mhz are my RAM, also Corsair with CL16) with some custom timings
 


I was worried this might be the case. So is my best option to try alternative RAM?
 
You can choose the easy method to replace the RAM or to learning overclock yourself your RAM. What i tried to make my RAM stable was to search for compatible RAM from my mobo and playing with the timings from same company with same CL. In your case Corsair, look for same CL and same memory size and play with that timings. After is booting to windows download HCI memtest or AIDA64 and test them for stability.
 


Ok, so I looked through the compatibility list and what looks to be exactly the same RAM as mine is actually listed.

I looked further, and this is the RAM I purchased:
https://www.corsair.com/uk/en/Memory-Size/Tested-Speed/vengeance-lpx-black/p/CMK32GX4M2B3200C16

this is the compatible RAM:
https://www.corsair.com/uk/en/Memory-Size/Tested-Speed/vengeance-lpx-black/p/CMK32GX4M2D3200C16

The only difference I can see is one letter in the product no. and one number in the latency. Would that really make that much of a difference?!
 
Yes. Is making a huge difference in stability because MSI tested that RAM with that timings and is stable. Try to set manual the timings from the RAM that is listed as compatible and try to run HCI memtest or AIDA64. If is not giving you some hardware failure you can go to test again the performance. Let me know how will go. For example my ram have 16-20-20-38 timings and in AIDA64 and HCI memtest is instable. But if I go for 16-18-18-36 with 1.2v are stable but is 2800Mhz instead of 3000Mhz. But i am pretty sure if i go for 16-18-18-38 and 1.35v i can go stable with 3000Mhz.
 

I was able to return my RAM and order the listed compatible RAM instead so I'll try that first. At least if I still have issues going forwards I can get support from MSI as I have compatible RAM. Thanks for your help so far. Will let you know if there are any improvements next week once the new RAM is installed.
 
I replaced the RAM and had exactly the same issues. Only 48GB detected and ran at 2133 even with XMP on and manually setting the clock rate to 3200. MSI support was non-existent so I've sent it back and have ordered the new ASUS ROG Zenith Extreme Alpha which will be here next week. Hoping for a better experience all round there.

I was worried that reviews of the previous gen ASUS ZE board seem to be mixed, but then I realised that's the same with every board out there!

Fingers crossed.
