Onboard sound and overclocking Phenom 2 x4 955

post #1 of 6
Thread Starter 
So this may sound strange but i got a hunch on something i remember from oh so many years ago. Onboard sound cards use your processor power to create sound. I was having a real hard time getting a stable overclock to 4ghz even pushing past 1.55 volts and 1.45 cpu-nb. Well i started thinking about this and began to wonder. What if i took my 7 year old audigy card and put it in and disable onboard audio if that would help. Well guess what... now stable after 9 hours of prime 95 at 4ghz and 2800 cpu-nb 2000 ht. now take a guess what kinda voltage im running. Mind you im cooling with air, cooler master 212 evo. 1.45 volts core 1.25 cpu-nb. I never see over 41c now. Crazy huh? Something else, i was having issues running serious sam 3 with my processor settings on high even on a 3.8 clock at 2400 cpu-nb but after just disable onboard audio and adding in the sound card. I went from a constant 25 fps up to 65 fps and never drops below 45. All this from onboard audio? surely not? Maybe it was bad driver install? I thought of that to and tested this in several different configs and evertime when i was playing a game my processor mind you without the 4ghz over clock and just disabling onboard audio i see a huge performance difference. 5fps top end +25 fps min in arkham asylum, no more drops to 4fps. So anyone having issues with an overclock or think, man this game should run better. Maybe trying a dedicated sound card could help. I'm not sure if it has been covered or not yet but just in case, heres an idea that can be tried. smile.gif

this is pretty strange:s
i disabled the onboard audio and i could lower the vcore with one step:-o
temps under load(30 min prime) are 3c colder and it runs stable so far.
seriously this is strange how can the onboard audio affect it so much:o

It might have an unstable voltage regulator.

This may be the reason my 1055T is now able to run at 1.425V for 4Ghz as opposed to 1.475V before!!!! I thought that mostly had to do with the NH-D14 switch.  Around the same time I transferred my setup onto a Xonar DG and new headphones.
