Windows 7 - Ram Problem.

Hi all,

I was wondering if anyone could help me with a problem I'm having with some ddr2 ram I just got. It's 512x4 but it will only register as 512 at the bios load screen and once Windows loads too.

So far I've scoured the net and have eliminated msconfig - boot - advanced options as the problem. Also looked in the bios settings but not very sure as to what I should be tinkering with. I've updated the bios but still no joy.

There was 2 other sticks of 1 gig in which I've tried removing so it was only the 512x4 in the comp. still same result.

The problematic ram is 800mhz if that helps any and the mobo is an Asus M2N-SLI Deluxe.

Hopefuly someone can offer some suggestions/pointers to remedy this. Thanks for reading, any help is appreciated.

If you did not buy all at once (mix and match, which is a no-no), that is most likely a problems. I know, they are compatible etc, but I stick to my answer.

Thing is though I've tried with just the one I'm having probs with installed, I was going to replace the current 2 working gig with 2 of the 512x4 ones but even when the single 512x4 is in it only shows 512 of ram.

You might be having trouble with the RAM sockets on your motherboard.

Take all your RAM out, and then try each stick in each socket - one at a time. A bit time-consuming I know, but it will tell you whether its your RAM sticks or your motherboard that is playing up.

Take this test, for both slots and sticks
Download memtest86 and test RAM
www.sevenforums.com/tutorials/105647-ram-test-memtest86.html
Run for 8 passes
If it passes try a good stick in each slot for 3 passes
If it fails do the same for 8 passes.

richc46 suggestion is the best way to test it. I would suggest to reseat the ram and make sure there is no dust or or trash in the ram slots.

What is the make and model number of the RAM in question?

Thanks for replies all. I think the guy has either sold me the wrong ram or has tried to pull a fast one or made a genuine mistake.

The ram is Vitesta - Extreme Edition - DDR2 800+ (4) 512MX8. The shopkeeper told me the (4) meant it was actually 2 gig, I assumed he knew what he was talking about running a computer shop. Then when I was trying to find a link to a page with the ram on it for you alphanumeric I noticed the 1 gig sticks also had this (4) in front of 1G, oh dear.

On top of that I tried what you said seavixen32 and this ram froze my comp twice when it was the only one in 2 of the slots

Have you tested your MB to see what is the maximum ram memory it can hold.

SIW is good to check this.

I've still got the box, says on the side it can hold 8 gig.
