Hi guys,

I have 4GB of Kingston HyperX 1066 RAM from Overclockers in my machine running Windows 7 fine. Somebody recently bough me another identical 4GB which I put into the PC. When I do this the mobo detects 8GB and posts absolutely fine, but as soon as Windows starts loading, things slow down to an absolute crawl.

Windows takes about 10 minutes to load. Once I'm actually logged in everything is ridiculously slow. When I take the 4GB back out everything is fine. The first thing I though was that I might have faulty RAM on my hands so I took out the original sticks and tried running the PC with with the new 4GB, which worked absolutely fine. It also works fine no matter whether I have the 4GB in slots 1/3 or 2/4.

In conclusion, things only go wrong when I have all four slots in use with 8GB and I'm at a loss as to why? Does anybody have any idea?

System Specs:

Gigabyte P35-DS3R
Intel Core2 Q6600
Western Digital hard drive
Corsair 520W PSU

RAM running at 1066Mhz (2.2V)
 
Hi Mark, welcome to the forums.

The first thing i would do is do a BIOS update. If you havent updated it since you built it, the chances are that it is out of date. Updates will usually have added support for different memory and CPU's. Not sure how you go about an update with your motherboard, but you should be able to do it via the BIOS. Use CPU-Z to check which BIOS revision you are currently using.

However, the fact that it POST's without a problem suggests it may not cure the problem. If you are unsure about updating the BIOS, wait and get a bit more advise. If you bodge the update process you can be left with a bricked motherboard.
 
Thanks for the welcome and the great advice guys. The BIOS update looks like it might well be a winner. I'll let you know how it goes :)
