CPU @ 3105 with onboard video..only does 2906 with 7900 GS installed

[winr]

My AM2 5200 + will do 3105 with onboard video.

When I plug my 7900 GS PCI-E video card in it will only do 2906 very stable.

3105= 13.5x230 HT was higher than below

2906=13.5x215 HT is 1076

I have set HT on 5, 4, 3, 2, auto, etc, it doesnt seem to change it according to cpuz.

1 SATA hard drive
1 SATA DVD drive
1 big Rosewill cooler
1 120 mm case fan
1 ANTEC Earthwatts 380 PS

Any advice ??

TIA.

Why worry about a 200MHz drop in your overclock? You are now using a GPU that is many times faster than your IGP. Start gaming where you couldn't game before! Have fun!:thumbsup:

Is the +12V rail dropping?
