hi, I have a Gigabyte GA-8IPE775-G mobo, P4 3ghz, Vista and 4GB of Zepplin DDR400 ram...the system runs fine on 2GB ram but as soon as I install 4 gb of ram it boots but once booted..after about 1 min it blue screens and reboots...anyone got any ideas??

I was thinking it is requiring a bios update but I dont have a floppy drive so cant use qflash..I tried the chipset update but no luck..it still reboots when I install 4gb of ram.

Please help....

Cheers

run mtinst.exe

click Save image to disk

burn the iso to cd.

boot with all 4 gigs ram. run the test for an hour.

wicked...will do. THANKS!

OK did the update, loaded the ram in and it booted, no blue screen....however...nearly everything that started with windows closed down...I tried opening outlook, it closed down...

So I rebooted and when it loaded back up it blue screened...but it looked like a different error this time...some screenshots below

This is loaded after update;

Then this is the blue screen once I had to reboot:

i'm pretty sure there's malfunctioning memory. did you burn msmem test to a cd, boot from the cd and run the test? looks to me like i wasn't awake this morning and my instruction wasn't as clear as it needed to be.

you'll probably need to test 2 gigs at a time with msmem test. i don't think it will test 4 gigs.

yep, did the memtest..all came back fine.

Also installed SP1 and did a bios update..still no go!

you have rev 1.2 GA-8IPE775-G? previous versions of that mobo supports ddr333 so maybe 4 gigs ddr400 is too much. ver 1.0 and 1.1 recognize ddr400 as ddr333.

nah I got REV 1.1 I did a bios update to F8, it sees a few hundred more mb of ram on boot up but still BSOD.

I did try limiting the ram on boot to 2048mb and it booted fine with 4 x 1gb sticks, showed up 4gb in control panel and didnt BSOD....so i am thinking of upgrading the PSU as I have heard this can fix it to accomodate for the voltage drop..

ok, 550w PSU in, didnt BSOD so early but eventually did...it was the IRQL Not Equal... one this time..not getting the emmory manager one...

It runs fine with 4 gb ram in safe mode without a hitch!

Here is 4 of the BSOD I got:
