Hi all,
I've build my TR 3960x over a week ago and I've taken it in production since a week now. Few things I have noticed and hopefully I can gain some insights in why I have a few small issues. Build:
CPU: TR 3960x + Noctua NH-U14S TR4-SP3
Mobo: TRX40 Aorus Master
PWR: CORSAIR HX Series HX1000
Mem: Corsair Vengeance LPX (128GB, 3200Mhz, CL16 (16-18-18-36))
SSD: Gigabyte Aorus NVMe Gen4 SSD 1TB
And I reused my gtx1070 and 980ti, runs on Win10, freshly installed all the latest drivers and bios etc. Questions:
1. After PC goes to sleep (or hibernation) and comes back, I have 1 logical processor sitting at 80% always. See screenshot (resource monitor shows the same values).
The active processes show not a single process that is consuming that much cpu usage. I've painstakingly eliminated one by one as many processes as I could and until the system was crippled, but nothing made even a slight impact on the cpu usage. I'm left wondering what causes this. I tried 2 different bios versions, but made no difference either. Anyone with a clue, I'd be happy to hear it! After a complete reboot the CPU is normal, but when out of sleep the problem returns. And it's always this core. Temps look fine when not under load: low to mid 40's (celsius).
2. I run the memory with XMP enabled at 3200Mhz. When I run cinebench with (3200Mhz) and without (2133Mhz) XMP enabled, my cinebench score is 3% faster on 2133Mhz than on 3200Mhz. This is a big surprise obviously and I have yet to understand why this happens.
3. In light of question 2, am I better of with 3600Mhz kit perhaps? Does TR work faster with a 3600Mhz kit and if so by what margin?
4. Are there any good overclocking guides of video's on this particular CPU, I feel I'm leaving some performance on the table, while I could still have a stable workhorse.
Thanks in advance for any pointers!
