once the bios has everything seen it will post fine and see all the mem.
Just let us know when you do this and what the result is
Also regarding the OS. Just unplug the HardDrive and test ! (Probably done)
Will let u know soon as i get new Mem returned to me. Why unplug the Harddrive?
Because all the strange talk above on 64bit and so forth !!! (That was fun )
"So if i go back to 2Gb system, install Vista Ultimate 64. Then insert the other 2 sims ur saying the board will miraculously see this other 2Gb? When it wont post the bios currently with all 4 sims inplace."
Just to be clear here, I pointed out that, in the links I could find;
1 - Asus NEVER claimed that mobo would support Vista of any flavour
2 - Asus NEVER claimed that mobo would support 8 Gb Ram in anything but 4 servers and XP PRO 64 bit.
Further, you wanted to know how to get into Bios and I said remove 2 sticks of Ram.
Yes all good info
But the question is why it won't post with 8Gig mounted, irrespective of the OS or even if the HardDrive was unplugged!
That may be a question indeed! But not what I responded to.
Were I the poster, I would investigate his Kingston DDR2 667Mhz PC2-5300 CL5 to make sure it is meant for SLI Ready motherboards and also check out the mobo SLI Memory Ready status as to whether voltage and timings are OK stock OR do they need to be set in Bios ahead of time.
