Odd RAM Question

paranoidandroid · 4 Aug 2009 at 19:03

I have a Gigabyte GA-EX58-UD3R Motherboard and at the moment its confusing the hell out of me.

I recently added Windows 7 to a separate HD just to see how it goes, essentially I now have a Triple Boot system, XP, Vista 64bit and Windows 7 64 bit.

I have the processor overclocked to 3.8 and its been stable at that, however what seems to happen now is sometimes when I fire up, even before I get the boot manager up to select which OS I want to run, the amount of RAM showing in the BIOS Post either shows as 2gb or 4GB and certainly never the full 6 that I have installed. Once I am in whatever OS I have chosen I see 4gb in XP which is to be expected, the full 6 in Vista, and the full 6 in Windows 7, albeit it says only 4gb is usable, all confusing

Anyone any ideas please as to why it would change? certainly in the BIOS post

Thanks

Paul

On the board did you make sure you plugged the sticks in the white slots and left the blue empty?

What model is your RAM?

Is the bios up to date?

Yes all put in the white slots, its corsair 3X2GB DDR3 1333C9

There are some memoery compaitbility problems on the x58 boards - most of them end up getting different RAM. A bit of a shot in the dark though.

Its the latest so far as I am aware - F6 I'm a bit stumped too

Without sounding like a willy.
But just double check you have really pushed the sticks into the slots on the board. Give them a good push down with your thumbs...
Maybe try running memtest and see if it throws up any problems with the modules?
What happens if you try one stick at a time? Is the 2GB from one stick usable?

Just the usual stuff I'm suggesting really

I have tried re-seating but not memtest. What I can't understand is why it posts 2gb sometimes and 4gb the next :confused:

its just...well irregular

It really is. Thats why I'm suggesting you try individual sticks maybe its one bad module? I hope thats all it is and not the board.

Yes try individual sticks in the blue slot and rotate them to see if any of them fail.

Well I have got my answer, albeit it has now created another problem, well pain in the ass issue. I increased my timings to the recommended 9-9-9-24-2 and the voltage to 1.66, voila!! 6gb RAM and my hard drives. Now my overclock has gone to pieces so although I am seeing RAM and HD's I can only get the system to run at stock 2.66 which is a bit of a pain...back to the drawing board

Awesome man, Glad you got that sorted.
I though Overclocking an i7 was a piece of cake huh?!

But anyway glad to hear you got your ram problem sorted!
