First post so hopefully this is in the right place.
As the title suggests, ive just finished my 3900x build. Its the first PC ive built for 10 years as i went the pre built route for last 2 PCs, last time i used an AMD CPU was a K6-2 400 back in the 90s (iirc) and the last time i did any real overclocking was on a 266mhz Celeron that everyone was bumping to 400mhz at the time... that gives you an idea of my age
Anyway, i did my research, understand the dangers and have got my PC to a state where its stable, fast and Im ok with the risk/reward ratio but still feel I may have missed something being a noob to all this.
Im looking to run the below details 24/7 and my PC is used for Gaming, Photo and video editing as well ask the occasional bit of real work (Office 365 etc).
System is as follows;
Asrock Taichi x570
32gb (2x16g) Crucial Ballistix 3600 ram
Corsair h115i Platinum AIO
2 x 1TB Sabrent Rocket PCI-E Gen 4 Nvme drives (1 x boot/applications, 1 x most played games)
2TB Crucial MX500 SSD 'Steam library'
Corsair 750rmx PSU
EVGA 1080Ti FTW ICX (carry over from my last PC as waiting on next-gen)
Settings/overclock wise I've got the Ram running at 3800mhz coupled with 1900 IF. Timings are 16-16-19-16-36 @ 1.44v (as per DRAM calc for Ryzens settings).
SOC is at 1.1v, VDDP at 1.0v and VDDG at 0.9v
CPU I have an all-core overclock of 4.4ghz @ 1.325v LLC 2 set in the BIOS (anything lower than LLC 2 needed at least 1.35v to be stable).
Ryzen master says I'm at 1.325v, however, CPUID shows 1.328v and bumps up to 1.344v under max load (R20/Prime) which i guess is the LLC kicking in?
Temps wise I see idles around the mid-30s, gaming around low 60s and R20 high 60s, occasionally creeping into the low 70s. Prime 95 after about 20 mins gets to mid-70s. I have seen one core fail at around 30 mins but I'm not too worried about that. I've not seen any unstable behaviors anywhere else.
Performance-wise I see improvements over PBO and stock. With PBO I was seeing split seconds up to 4.575ghz on one core and a couple more on that CCX getting to 4.5, however in the main they mostly hovered around 4.35 at best. I did follow the guidance on tweaking PBO through PPT/TDC/EDC and did see improvements but still below that of the all core O/C.
I get the same single-core result in R20 (509) with the all-core clock as I do with Auto/PBO and see a jump from 7196 to 7750 on multicore.
FarCry 5 renders about 200 more frames with the all-core clock in the benchmark with the average FPS going from 109 to 111 at 1440p maxed out/hi-def texture pack. World of Warcraft seems to have 5-10 more FPS standing around in Boralus Harbour with the multi core overclock but this is hard to verify of course.
So generally very happy with my first AMD build and overclock of this century , im even pleased with my cable management in the Fractal Meshify S2, that was so much nicer to build in that my last one
..but still nags me that its all gone too well so I may be missing something or misunderstood something.
I know some may consider the Vcore a little high, especially when the LLC kicks in, but as I said I'm happy with the risk vs reward as I always like to get the best out of things but i acknowledge im new to this platform so willing to listen to anyone that thinks I'm pushing it too hard for 24/7.
Any advice would be greatly appreciated. Thanks all
