I am a complete newbie with OC'ing. This is the first rig I put together. I have spent the last few days trying to figure it out how to OC and sadly I have not gotten very far. I have had this rig for over a year. . . it is time to OC!!!!


So far I have used Trixx to try and OC my GPU. After a lot of testing all I can get out of it is: GPU Clock 1135, Memory Clock 1500, and VDDC (voltage) 1187. 1135/1500/1187. Not terrible, but I am sure it can go higher. I am using 3D mark to test stability. If I go any higher it crashes. I am not sure if AMD's CCC would conflict with Trixx, my research says it doesn't. Also, I have VirtuMVP installed (not sure why), which I need to disable to prevent crashing 3D Mark.


With my CPU, I have just been using my MOBO's automatic CPU OC settings. I first tried the 4.4 GHZ and a lot of things were crashing. Including web pages. So, then I tried lowering it to 4.2 GHZ. At 4.2 GHZ settings it was more stable, but as soon as I tried 3D mark test it crashed. So, CPU is at stock currently.

I know my CPU and GPU should be able to OC fairly well. I don't have the greatest cooling system so I want to avoid raising the voltage, but I do want to get a little more out of my rig. Any help would be greatly appreciated!

Thanks,

what's your psu?

using the auto overclocker in the bios is a no-no... i wouldn't recommend it anyway.

and gpus can vary. its silicon lottery. i would first find the max cpu then the max vram frequency at stock voltage, and go from there. i also prefer msi autoburner over trixx

Lol didn't realize my PSU wasn't listed. Thank you. I have updated it. I should have enough power though with 750W (estimated needed 450W). I will look into MSI Autoburner. Thanks.
