Updated post #2 in this thread with Intel D975XBX Badaxe FSB and Memory clock calculator http://i4memory.com/f55/semi-official-intel-975xbx-badaxe-motherboard-info-2804-post43401/#post43401.

I'm using 106 - 107Mhz, but last night tried to boot for benchies with 108Mhz and got HD corruption.
No amount of NB volts did anything to help this.
I can't rule out PSU though. Trying to overclock X1900XTX and dual core cpu around 4.5Ghz with several other devices running is pushing the limits of my Antec 550W psu.

I'd say that depends on the Mobo and PSU quality.

Previous version of Intel DCC didn't work for me using 1304 bios, but this v2.1.0003 works fine

Interesting the temps are a bit off for me by 4C between Intel DCC vs Coretemp



Intel DCC shows actual bios option values you set for vcore, vdimm, mch, fsb etc not the actual readings. For example 1.4v vcore in Intel DCC = 1.371v vcore reading in bios.

Load temps dual stressprime



Also looks like there's a new official 1334 bios out now.

sweet looks like 1334 bios allows you a higher fsb limit on bad axe http://www.xtremesystems.org/forums/...d.php?t=107653

Hmm just flashed to 1334 bios and now Intel DCC v2.1.0003 doesn't load properly guess need to wait for next DCC version lol

see DCC temp doesn't even budge from 35C under dual stressprime load with 1334 bios loaded

Added an FSB:MEM table showing all the positive burn in percentages and coressponding FSB and MEM clocks for Intel D975XBX Badaxe

Have just ordered this Intel board and confirmed a revision 304 and am able to collect it tomorrow.

So my setup will now be (as of tomorrow):

Intel BLKD975XBXLKR i975XBX board

E6400 CORE 2 DUO /2.13GHz/2MB CACHE/1066FSB/LGA775

Corsair Twin2X 2048MB 240-pin DDR2 XMS2-6400.

As this board is on the official Nvidia list of 7950 compatible boards I decided to go with it..until the "Real" Nvidia SLI capable boards arrive anyhow.

I am not into overclocking..I just want a good reliable gaming platform.

I hope I made the right decision.
