** Sorry if this is in the wrong forum, but it seemed like the bizzaro world alternative to overclocking and seemed appropriate. **
I'm currently trying to undervolt my CPU then North Bridge then maybe GPU then RAM?
This is my first time, so I'm obviously trying to learn the in's and out's.
My system Configuration:
Phenom 2 x4 945 with Stock Cooler
Gigabyte GA-MA790GPT-UD3H
2x 2gig G. Skill Ram
Sapphire Radeon 5850 1gig
Testing Tools:
Prime 95
Furmark 1.70
OCCT: GPU
HWMonitor
Rundown of situation:
Undervolting CPU seemed easy. I was getting down to 1.1125 volts at 3000 clock and prime 95 with small FPU went without much issue. Then tried the same with the Northbridge; Got to about 1.250 prime 95 blend tests (with cpu still at 1.1125). (This is only for P-State 0)
Tried OCCT:GPU (45 minute run, shader 8 complexity, error checking full screen) (Prime 95 Blend in background) and it would restart sometime in the test - maybe 5 minutes in.
Read that Furmark was preferable over OCCT, it seemed to run better, but then would restart or blue screen around 800 seconds. (Furmark settings: 8x MSAA, Post-Processing, Stability Test, 1920x1080 Full-screen)
Now retrying my CPU and NB voltage combos with Prime 95 blend and Furmark and while they run, I've noticed my average FPS drops with my CPU voltage.... that doesn't seem right considering undervolting is suppose to keep clock speed otherwise it would be underclocking.
Finally, I read that Furmark was crippled by catalyst software.
SO,
- What do you think is happening?
- What could I have done wrong?
- Is there a better method of testing?
- Is GPU undervolting possible (it's the one I haven't seen much when searching online and undervolting in general doesn't seem to get much current hype)
Thank you and sorry about the long post, I try to be concise... I just don't do it very well.
