Overclocking help after installing video card


Recommended Posts

My first post at OCC :) Have loved the site so needing help I figured id come here.

 

Asus m4a785td-v evo

Phenom II x4 955 CO stepping

4ghz ocz platinum 1333 ddr3

sunbeamtech core contact freezer 120

antec trupower new 750w

 

Im having issues overclocking my cpu AFTER installing the hd 5770.

Prior to installation I had my cpu running at 3.9 19x205 @ 1.406 V. After installing the video card, everytime I game or run a benchmark the computer crashes and my bios post message says overclocking settings failed! The gpu and cpu work perfectly fine and completely stable with the cpu settings all on auto. 3.2ghz. But when I even attempt to overclock to 3.4 I still get the crash.

 

Bios is latest edition for my asus board 2002.

Settings overclocked perfectly stable without graphics card: 3.9ghz 1.406v, cool and quiet disabled, all cores, bus speed 205, HT 2050. The only voltage I changed was the cpu overvoltage which I set at the 1.406 specs with load line calibration set at 0. My ram runs perfectly stable with the graphics card or without it at its same 1333 7-7-7-20 @ 1.8v (all factory settings for the ram).

 

Is there some other voltage I need to change since the graphics card was installed? Or some other setting? Im lost here. Any help is greatly appreciated, Thanks!

Haven't messed with an AMD in years so I'm not familure with all the settings.. whats the PCI bus running at? Should be 100, I know on some cards you can go a little higher but not by much.

I ended up solvin this one after doing some more research. Turns out even though my bios kept telling me overclocking failure that wasnt the casue of it. I ended up having old nvidia drivers still on my computer which I fixed by doing a driver sweep in safe mode. After doing that in reinstalling catalyst drivers the system is running perfectly again. Seems to me if all else logical fails, its gotta be the drivers :P
