GPU under performing after CPU overclock?

[ElementalxVenom]

I used userbenchmark to test my computers strengths, and discovered my GPU was under performing.. After a bit of tinkering i removed my overclock on my 9900k and ran another benchmark, this time the cpu was as expected and the gpu was "above expectations". I re applied the OC and GPU is back to under performing. Could this be due to a not sufficiant power supply? Thanks.

What components are in your build?

 

And are you sure the CPU is actually stable? I am literally in the middle of battling my 9900k, can't get it stable at 5GHz for the life of me :/. Stuck at 4.9.

 

When you apply the CPU OC, is it for some reason removing the XMP option and thus underclocking your RAM by chance?

The full specs are in the userbenchmark list, I have no problem with it disabling xmp or messing with ram, however I do require 1.39v to get 5.0 on all cores.

Thats.... a lot of vcore. I would not be anywhere close to comfortable running that much vcore, and cooling that would also be pretty difficult.

 

How are you testing stability? What is your cooling solution?

 

All I can really think of would be its not actually stable, or your XMP setting is being removed and your speeds are not correct. What does CPU-z say, or hwinfo64?

 

Also, in hwinfo64, at the bottom it has a WHEA error section, have that open and see if you get any errors while running the benchmark. This would be a sign of CPU instability, and could potentially be causing issues.

Ehh I ran 1.4 on a 6700k for 3 years and it was fine. My PC blue screens when I run cinebench so I guess it's not really stable however in gaming it's fine. I'm not sure why I can't get a stable 5ghz when others have it at like 1.25 as I've seen on other forums. My motherboard does have two power cables for the cpu however my psu only had one to supply it, could this cause any problems? Cheers

Thats also a lot of volts, lol. I would be very interested to see if the plausible instability is whats causing the issues...

 

And no, no real need to run the extra power cable, a single 8 pin is good for at least 250 watts of power, which is plenty. 

 

5 GHz is harder to hit now with the 9900ks existing, the chips that can do it end up as Ks's which hurts the silicon lottery chance of getting a 9900k that can, this is why I am more or less stuck on 4.9 GHz as well. #firstworldproblems
