slower cpu at higher ghz

post #1 of 17
Thread Starter 
after i done some tests i notice that the cpu becomes slower on somethings and faster on others, doing some passmark test and then compared and my 3,6ghz was 6,8% faster overall then 3,8ghz by another 955. is this something normal or is this just *** confused.gif and oh, when i had mine on 3,5ghz it was faster then it was with 3,6ghz at exectly the same things that the 3,6 was to the 3,8

(the 3,5ghz and 3,6ghz is my cpu and the 3,8 is just another 955 to make things clear so its only the same system on 3,5 and 3,6)

download linx and note the gflops at stock, 3.5ghz,3.6ghz and 3.8ghz

oh never mind your comparing your oc performance to someone elses.

your oc could be more stable resulting in higher performance, or it was just binned higher.

yeah the 3,8 is someone elses, but its the same things that gets slowed down and speed up between my 3,5 and 3,6. its exactly the same things, thats what i find a bit odd

What you don't want to be doing is overclocking that far on that board.
Brace yourself, I can smell the flame death from the 4 phase power blowing up already...

TL;DR, return to stock... or even lower... until you can get a better board. High TDP + small power phase, unheatsinked can be fairly dangerous.

I am not exactly sure what you mean by "4 phase power"? Do you mean the motherboard uses only a 4 pin molex for the cpu?

Lol biggrin.gif, you shouldn't be OCing.

The only time Higher Speeds are slower is when they are unstable...

No, power phase and connector don't have anything to do with each other. The board has 4 phases of power to the CPU (not even 4+1 because it is AM2 based and does not have split power), running this with a 125W processor can be especially dangerous due to the higher load of each phase/channel (25% of the entire power load) vs. with more channels, and the fact that your processor at stock is already 125W which means you would be more than pushing the limits with the weak power phase. Heatsinked it can and might perform better, but without heatsinks it just gets worse. A quality 4+1 phase (i.e. with low RDS) from a decent board manufacturer may be fine for overclocking, but this is a very low end board and the power phase isn't even split phase on this. Don't make me post my flame death horror stories - and believe me, I've collected a lot so far on various boards/manufacturers.

lol no, to put it simply power phase means how many times the power is cleaned up.
the red are the chokes those basically clean up the power. the blue are the Mosfets those drop the voltage from 12V to the voltage the CPU runs at. and from what i understand the orange is the digital mosfets i don't know what they do.

Lol, this.

I'm pretty sure the power phase/VRMs convert, regulate & supply power to the CPU. I'll trust you with the phrase "clean up" but I have no idea where that came from, and I don't think it would be so easy to understand from someone who doesn't even know what VRMs are. I believe the orange are the MOSFET drivers. With 125W processors you should seriously be looking at spending on boards with larger 8+2 phases, and heatsinks on them as well. These two factors are a MUST also if you will be overclocking 125W processors.
