Winflash tells me "load the correct bios file..."...i just can flash an older one, but not this C28....why ?

flashed using awdflash okay here.. fixes 5:8 divider at least 400fsb 5:8 640mhz 5-5-5-15 memtesting!

3:5 still has problems but 5:8 seems fixed

think ive got mine orderd from that german site :confused:

as i dont have a paypal account i had to order it the odd euro IBAN number thingy way. i ended up going to the bank to do it & even then the casher had problems sorting it out lol.

can't wait now :D , i got a cool little e6750 (1.4 vcore for 3.7Ghz) ready for a thrashing .

that reminds me i need to do a sig up.

Thanks eva, do you happen to have any recomendation for using the 2x2gb pc2-8000 GSKILL kit. What settings, secondary timings etc... Will probably be on the 1:1 divider in the 850-900mhz range, hopefully cas 4.

Thanks

Thanks so much praz, and just under 2V on the vdimm, very nice, very nice indeed.

The key to the G.Skill is tRFC. Start at 52-54 and work down from there.

what are u doing to kill it 3V vdimm or bad gtl settings or unlucky ness

Praz would up'ing the PCI-E clock to 101mhz help any? seem'd to help my 965.... unless it was just idle hope ;)

Haven't used my 2x2GB Gskill kit on this board yet, but what Praz says is important tRFC needs to be loosened alot on some boards for gskill 2x2GB PC2-8000 kits and optimal voltages between 2-2.1v.

Clock fine delay tuning may help too http://i4memory.com/showthread.php?t=4743

Praz, interesting tool you have for hands free DMM measurements :)

has anyone tried a penryn dual core on here rather than a quad? i.e. E8500?

[edit] mine has been shipped - Scheduled Delivery: 10-January-2008 :D [/edit]

[edit2] just to clarify, my x38 has been shipped, not an e8500 [/edit2]

Thanks eva, will have a look at that i4memory thread when the site is back up.

Graphics cards come tomorrow, so after a water block setup on those, will be up and running, and will finally be able to try this beast out.

Visiontek 3870's from bestbuy.com, got 'em for $198 each shipped because of reward zone member. Slow shipping, but the price was right.

Hasn't made any difference for me but would be worth a shot.

They're from a company called AG Devices. They have different interchangeable heads also. This one's handy for dual measurements on an SMD device.

im putting nearly 1.5v to the nb and 2.27 to the ram and it wont boot stock settings for tracers.. do i need to rma these ?

pay attention to which mem dividers you use prior to 12/28 bios 5:8 divider won't boot your system

12/28 Beta Bios - 5:8 divider tests
Previously on 11/28 bios, certain memory dividers had stability issues. 4:5 divider couldn't do more than 440FSB, 3:5 divider had issues of stability even at 333FSB due to tight performance level of 4 and 5:8 divider wouldn't even allow system to boot regardless of cpu FSB set.

Now 12/28 beta bios http://www.dfi.com.tw/Support/Downlo...FLAG=B&SITE=US has at least moved one step closer, with fixing the 5:8 divider.

From 11/28 bios 5:8 no system boot, to 12/28 beta bios doing 400FSB 5:8 640Mhz 5-5-5-15 on memory! Having some difficulties tuning clock fine delay for above 400FSB on 5:8 so far since using 2x1GB Crucial Ballistix PC2-8500 Tracers on 2:3 divider manages upto 681mhz 5-5-5-x more easily!

5:8 divider needs slightly more vdimm than 2:3 divider but still pretty good for 640mhz 5-5-5-15 at 2.35v bios set.

- Single Super Pi 32M = 13m 21.485ms

Just wondering what NB heatsink everyone is using on the DFI x38? You using stock heatsink with what type of fan or did you buy a whole new nb cooler? just wondering.
