Hi guys,

just picked up this new motherboard last week however yesterday my pc started lagging like hell! this includes stuttering and skipping on you tube videos and benchmarks. The only thing to sort is was to load default BIOS settings

After hours of changing things one by one I have found that my "CPU NB" is causing a severe loss of performance on anything above the stock 2200.

I had disabled all power saving options, tried adding a bit of extra voltage here and there...

Prior to this I was sitting on 2400 very nicely and now I must be on 2200 or system goes wonkers.

Any help appreciated guys

Spec:
