Yes, I have the most current bios. Without custom settings, this board detects my RAM with the wrong speed, wrong timings and wrong voltage (1066, 7-7-7-16 & v1.5 respectively). I confirmed this with Gigabyte tech support. This RAM isn't officially supported.

i loaded up cd and everything but it wouldn't boot up in the boot up screen.. i don't have floppy or anything.. just cd/dvd burner. last night i tried to test large fft at 9-9-9-24 instead of 8-8-8-24, and it was a lot better than 8-8-8-24. any ideas?

Excellent guide!

Here is what I got
7-7-7-20
190X21 @ 1.28
D0 Batch 3849A911

If i push the volts to 1.42 I can get 4.5 GHz

Anyway.. I love the guide and great work!

could you give me more details on your bios set up? cause i can't get mine to hit 4.0ghz complete stable.

like memory voltage and etc.

samx109 what are your bios settings, we re using same mobos so i should be able to help u. whats your problem atm ?

samx109 · 08-08-09

when i used prime95 small FFT test, it was stable for 16+ hours. but the main problem i have is that my computer is not stable on the large FFT test..(1hour stabalitiy) my ram is at 9-9-9-24, and if i drop that down to 8-8-8-24, it won't even handle 8mins of large FFT test.. another problem is that my memtest won't even boot up through cd... i tried different brands and everything, but it wouldn't do anything at the boot screen, and it'd just go directly to my windows loading screen.

what should i do?

vcore -1.25625v
pll -1.88v
vtt -1.33500v
dram -1.64v
ram timing - 8-8-8-24 1t 1528mhz
ioh/ich -1.2v
powersaving options -all disabled.
turbo - enabled
c1e -disabled
pcie freq -100
llc -enabled

here is a better resolution if you can't read the numbers.

Did you burn it as a bootable? did you select to boot it from a menu? Try going into the bios and selecting your cd drive as the default boot drive. It may not default to cd boot. Also, try increasing the voltage on the ram a bit. To be honest it sounds like you may need to rma.

@Daphnis: Thats normal for a board to do that. You'll need to put in your own timings and speed.

@chadamir:

See this post again. If I leave my board at stock settings and manually adjust the RAM to its specs. I have no problems. When I overclock with the specified settings and run prime95 for 8 hours, no problems. When I reboot and run memtest on the same config., after less than a minute it locks up at 7%.

it seems like something is wrong with our memories.. i got the same ones.
