Abit IX38 QuadGT Bios Update?

GTLREF adjusting? Which core are unstable in prime95?

GTLREF adjusting? Which core are unstable in prime95?

Bluescreen or complete system crash (mouse stuck) so don't know...

Can't raise my Vcore as I get an idle voltage of 1,46V for 45nm Quad already => lethal!

Stupid Vdroops!

my Q9550 E0 is stable at 461x8.5 ram 922mhz 5-5-5-15 (i have 4 x 1G ranked 1150mhz)
vcpu 1.350
vtt 1.47
vmch 1.42

my mb (all ix38?) have problem with the ram over 930mhz :/

I think you have to increase Vmch a little bit more because 4 modules of 1GB each stress the MCH a lot more than a 2x 2GB setup. Try increasing it to 1.50V and then see what happens ;-)

VTT over 1.35V is way too much for 45nm chip...how's your temperatures for CPU in idle?

True that, didn't notice it yet but indeed CPU VTT > 1.35 is killing the CPU slowly...
Try to lower the CPU VTT and increase the MCH and see if it works... I would do it
asap to keep you CPU alive...

Nice notice Dizel

Link to this x_15 bios is dead can you upload it again or sent to me pls.

Hi,
I'm a novice here, so the reason I register, because my Ix38 quadgt is very hot and the cpu starting tempreture is 53 celsius.
As I read there is a beta bios which is solve this question, but the link hasnt existed yet. So how can I contact anybody who has got this beta bios or similar problem?

Beta BIOS for the IX38 QuadGT:
ftp://91.121.194.115/pub/download/bi...0-stepping.zip

This fixes wrong temperature readout with 45nm CPUs (Core 2 Duo E7xxx/E8xxx, Core 2 Quad Q8xxx/Q9xxx, Pentium Dualcore E5xxx/E6xxx, Celeron Dualcore E3xxx).
If you're not using a 45nm CPU and still get high temperatures, the problem might be the cooler itself (or you're using a Pentium 4 hotplate )

Create a DOS USB Stick and copy the contents of the .zip onto it.
Boot from it on the IX38 QuadGT and type "runme.bat" and hit enter.

You can create a bootable DOS USB stick (or bootable CF/SD-Card in a card reader.. doesn't matter) with a utility called "Rufus". You don't even need to install it. Just use the portable version.

Hi Bambooz,

I dont even beleive that somebody will ansver, so thanks a lot.

I'd like to ask you that is the same beta bios that Infected mentioned?

"I recently downloaded the last bèta bios
"m704b" from the "BIOS updates for Intel E0 stepping"-thread. And
that BIOS works very nice for my Xeon Quadcore X3370 (aka Q9650 E0).
Thank you very much already, even Virtualisation Technology and the
CPU temperature reading is working correctly now"

Or I have to modify it to xeon cpu?

I use an X3363 xeon proc, and the motherboard was coming from Berlin in a few weeks before.

Thanks
Regards
Otto

Hi Bambooz,

As I've learnt there is a significant difference between X3370 and X3363 what I haven't known until now. The socket is different, but that cannot be differs regarding the bios. This is just a note. As you think I made my socket to fit 771 xeon also.

Otto

Hi Bambooz !

Maybe because this is not EO stepping, but it doesnt work !

thanks anyway
