Hardware / Re: Threadripper 2990WX
« on: 2019-04-12, 14:08:23 »You could try manually inputting all the timings and clock for memory without having XMP set it for you (it sets all sort of other stuff as well, potentially overriding your overclock/power settings).
AVX code is still affecting AMD architecture in Corona, so there will never be absolute parity with something like Cinebench or Vray, I've asked devs multiple times about this and there is no way they can get rid of it due to their compiler.
3.3-3.4 +/- is the correct all-core speed roughly for 250W ceiling/default settings.
I had all sorts of odd shanenigans where the Spectre hot-fixes bundled with regular Windows updates (every 3 months +/-) would cap the 2990WX clock at 3.0 for 250W all-core due to affecting power settings. But outside of that, no issue with memory clock/timings. This sounds like XMP-profile/AVX-turbo issue.
Yea, shortly after my post i set frequency to 2933 manually and put 14/14/14/34 while voltage remained at auto (1.35) and im getting 1480-1500 points now, so you are right, its something wrong with XMP profile. PPT is hitting 100% again while rendering in Corona but at least, CB score is same. I think i hit ceiling with memory and stock CPU clock.
Also noticed that if i set offset to -0.125mv like before, it cuts my score by 200 points which wasnt the case before with old memory set. Undervolting wasnt affecting performance but now it does. However, temp is sitting at 58-59C now which is okay i guess (was 49-51 with undervolting).
My decision now is all about silent + cooler PC with little performance drop vs stock voltage, little perfomance boost but noisy case. 58-59C is that stupid treshold where fans are starting to blow up quite a lot. Or even setting everything to default, i dont really feel any performance gain. At 2133mhz clock, CPU runs cooler and i cant really see any difference between 3000 and 2133 except aida benchmark
