Hey all,
I recently put together a rig for my nephew and have been having a play around with it to see how it runs, and as part of that I've been tinkering with the clocks a little to see what I can get out of the thing. Relevant specs are as follows:
AMD Ryzen 5 1600X
Corsair H100i Aio
16gb Corsair Vengeance RGB Pro (2 x 8) 3200mhz
EVGA SC GTX 970
Asus TUF B450M Plus Gaming
EVGA 850 GQ
I've been using Passmarks Performance Test 10 as my bench. I know, not exactly the best bench out there but it's one I'm familiar with, plus I'm only using it to get an idea of how much I've improved (or not) the different performance points of the system.
And so, this brings me onto my issue. At stock clocks the CPU (3.6ghz, 1.375V) and GPU (1317ghz GPU, 7010mhz Mem) scores were as follows:
CPU - ~13,000 (50-55C max temps)
GPU - ~8800 (65-70C max temps)
After OC'ing the GPU (1417mhz GPU, 7510mhz Mem) but NOT the CPU, the scores were as follows:
CPU - ~13,000 (as before)
GPU - ~10,000 (70-80C max temps)
Great news right? So then I turned my hand to the CPU and started fiddling with it's clocks, got it running stable (4.0ghz, 1.4V), ran the bench again and got the following scores:
CPU - ~14,000 (60-70C max temps)
GPU - ~8000 (65-70C max temps)
As I'm sure you can understand I was petty taken aback when I saw the staggeringly low GPU score after the CPU OC. The GPU clocks were still in their OC'd state, the only thing that had changed were the CPU clocks. I know from experience that sometimes power/thermal limits on the CPU can negatively affect GPU performance, however given the still more than reasonable CPU temps coupled with the fact that the score was improved modestly, I can't see this being the issue? However I will admit that this is my first time OC'ing a Ryzen based system so I won't be so bold as to assume I'm doing everything correct.
I will also note at this point that I reverted the CPU clocks back to default (as they were during my initial GPU overclock) and the GPU score went straight back up to where I expected it to be. So I'm certain it's something to do with my CPU overclock that's causing the issue.
So yeah, if anyone has any suggestions or could shed some light as to what's exactly going on here I'd very much appreciate it. Thanks in advance!
