Cant get BH5 stable :(

[Negative Design]

Hey,

I got 3 sticks of BH5 256MB and tested 2 so far individually and reached a somewhat stable 250 FSB(will test 3rd stick soon)I'm using DFI infinity with TicTac 2-15 BIOS(heard it was best)

I did 250 but can go any higher,also CPC wont work(NF2 problem I guess) I'm prime stable and game stable but not USB stable :( my keyboard and joysticks stop working/responding at times but the mouse still works and system doesnt freeze,games continue running but KB and Joy stop functioning...any ideas what could be causing this and how to fix it? fixing this may get me high FSBs too :)

Also using 9800pro XT flash,XP mobile 2500 @2.5ghz 3 HDs and njust got OCZ powerstream 420,,,my old thermaltake 420 wouldnt get me anywhere with my BH5s.

What voltage are you trying to run 250fsb at? Maybe you're not using enough. Also, CPC off is a huge performance hit, have you tried lower fsb with it on to compare numbers?

Im always at 3.3v CPC is only stable at low speeds like 200 FSB :(
I think the ram has reached ts limits :( only one of the 3 is fully stable at 250 I just tried it and it runs games and prime perfecly with no USB problems but the other 2 have USB problems :(

I found other users with this problem its called "Lan Drop" it can be fixed by updating ACPI drivers or getting new BIOS,I did the ACPI fix and havent lost Lan yet...I will push my system farther just to be sure.
