Windows 7: System doesn't want to take 8GB or ram

03 Jul 2009   #31


Incorrect. It is *not* obvious that it is a *bug* in W7 b/c, as I mentioned earlier, drivers are needed to make the OS work with the hardware. If your mobo manufacturer has not released drivers for your mobo that work with / in W7, and W7 itself does not have any applicable drivers for a device or has a generic one that is not enabling correct features of parts of your mobo, then you will have issues - and that is in *no way* a *bug*.

You are Welcome bob. I m sure that none of the memory sticks or the motherboard slots are bad. Its just that windows 7 is not taking it. its just a matter of more 3 months. Final release is on 22nd Oct. and I m from mumbai too.

you suggested early on to check for latest BIOS, which I replied I had. OOPs! I checked again and I am wrong, I had 1001, latest is 1203, so I guess i'll give it another try with the correct BIOS. My bad.

I know you have gone trou every possible variation. could it be a bad memory slot?

Im clueless, we have gone thru everything i can think of
you have tested the memory, in the 4 slots and it passed, have upgraded the bios, is there also a chipset upgrade for your model?

The BIOS update may be a major factor - but I am still betting on Windows 7 *specific* drivers for your hardware.

If the bios update and driver fixes don't work, you could try this: boost your FSB voltage by a notch. In my case, that was +.06 volts. My mobo and yours share the same northbridge chip, and the small voltage tweak cured my random crashes and surprise reboots.

Okay, do you suggest we install vista 64 first and test our setup just to make sure its not a hardware issue?

This would be a good idea.

Sorry this took a while. For now I found the time to try and fiddle with the voltage thing as I got that suggestion both from stevieray here and another guy in the MSI forums.. but, turns out I can't fiddle with it on my BIOS and am wondering if doing something wrong or looking in the wrong area. Hopefully will find the time to do that install vista 64 bit this week, but for now I know the hardware and the memory test recognize all the ram. Thanks to all those that have been replying.

Voltage Range

Windows 7 Professional 64bit

I don't know if this would help, but I had a similar issue with my Asus P5Q Deluxe mobo.

The bios was supposed to support 8GB and the board likewise, but there were constant issues.

In the end I went onto the forum of the memory mfr, in this case Corsair, and they advised me that voltages still needed to be altered to take advantages of the bigger memory. Just because the board is capable of taking 8GB, there is nothing to say that it is set up to from the start. The corsair forum was great.

Also I bought a matched set of 8GB, when you fill all the slots, boards get quite sensitive to voltages etc. I doubt it is anything to do with 7 per se, maybe that 7 is just fussier, or more sensitive to such things.
