DFI NF4 SLI with FX55 best settings for OC

[maverik-sg1]

Guys,

Got me an FX55 from Animal that would bench at 3.4Ghz.

I am struggling to get 3.2Ghz from it at present.

Ran memtest and BH5 is good for 270 2-2-2-5, ran CPU at 268x12 with CPU and no memtest errors - managed to 3d bench at this speed.

Superpi 32m test and video encoding stable at 265x12 = 3.18 Ghz

HTTx4

CPU Volts @ 1.5

Start Up @ 1.55

Special VID control @ 126% = 1.84v total for CPU

BIOS is 326 - PSU OCZ Powerstream 520w

2x 6800GT @ 448/1170 (BIOS FLASHED clocks)

Anyone with similar set-up, please post your settings here for me to try.

Hey Mav,

I think you need to change the HTT to x3 when getting above 260fsb. I kknow I certainly do.

Try looser timmings on the ram can you boot into windows with those tight timmings my tccd will do tight and pass memtest but windows craps out

No it's the voltage that makes all the difference. My fx55 would go to about 3.3Ghz on 1.75V on my old A8V but struggles with 3.2Ghz at 1.66V (max on my A8N)! 3.2Ghz at 1.5V is very good, but you are using a DFI which does that voltage boosty thing.
