P35-DS3P and 2/8G kingston ram

P35-DS3P and 2/8G kingston ram
« on: October 29, 2010, 08:29:24 am »
I may have jumped the gun on buying this as an upgrade.

I had 2gb of ram in my P35-DS3P motherboard and all was well.  I wanted to upgrade to 8, so I bought Kingston KVR800D2N6K2/8G ram, 2 sticks of 4gb.

The computer boots fine, it recognizes 8gb of ram, but my processor is now pretty much constantly around 30-50% cpu usage on a clean windows 7 64-bit install.  If i switch everything out and go back to the 2gb, it works fine and the CPU is no longer in constant usage

Is this an incompatibility problem with the board not accepting 4gb sticks well or is there some other potential solution to this?

Hi
I am afraid you have bought modules that are not compatible with your motherboard. It will accept 8 GB memory maximum but only in 4 x 2GB sticks. It is always important to check before purchasing the RAM.

before returning and ordering a replacement, would this be compatible?

I have only checked the Gigabyte QVL and not the Kingston (I will leave that to you) but the memory is not on there. There is some very close (KHX6400D2LLK2/2GN) but not exact and so I couldn't say it would be compatible for sure. You didn't say what revision your motherboard is so I checked against the oldest rev1.0 and the newest rev 2.1 The memory I quoted came from rev 1.0

Personally I think there is a good chance it would work if you have the early revision board but it is a gamble.

If you want to check yourself here is the link:
