W7 64 bit ram issues (install and boot up)

Doncre · 05 Oct 2010

I have search the forums for a full answer to this but havent found anything.

I tried to install W7 64 bit to a new SSD drive. it took about 6-7 hours and wasnt successfully. After following some advise on these forums I took out 2 of my 4 gig and the install took 20 mins.

If i go back to the full 4 gig W7 will not boot up. It is fine with 3 gig.

How do I get it to boot with the full 4 gig (other 64bit will be wasted)

The memory is 4 x 1 gig OCZ memory (bought as a set) 4-4-4-15.

Hello Doncre, welcome to Seven Forums!

You may have a bad stick of RAM or a bad DIMM on the motherboard. Download and burn Memtesr86+ to a CD, then boot the CD and run several passes with one stick in the same DIMM to start sorting if something is bad, it will take a while so be patient and let it work.

As it comes as an ISO file you may need the program at this link to burn it to CD.

I have swapped around the ram I have so i know that it boots up with all of them as long as there is only 3 stick in at any one time. having said that i will still run the tests

Okay all 4 dimm slots work and all 4 sticks are okay but it will still only fire up windows in 3gig mode.

Can you run CPU-Z & post a snip of the memory reading ?

Doncre · 06 Oct 2010

Here they are I know that its in 4 and not three but that was to prove the slots work

Have you checked to see if there is a BIOS update for your board? Go here to download the latest BIOS: MSI P6N SLI BIOS

I thought I should add to this that the machine was fine with all slots filled when booting into XP on a different hard drive. (althought it didnt see the 4 gig, the system booted okay)

The bois bootup see all the memory, it just when you get to the start windows logo screen it hangs.

Maybe you need to update the BIOS to support Windows 7. Usually there are BIOS updates to support new OS when they come out. Follow my link above to make sure you have the latest BIOS installed.
