Trouble with Kingston KVR400 and A7N8X-DX

[Shagger]

I bought 2 sticks of Kingston 512MB at CC and put them both in my ASUS A7N8X-DX. Now it seems that I have a little bit of instability. Ran PRIME95 and got some errors. Swapped the sticks around and ran it again, still got errors. Upped the voltage to 2.7 and it SEEMS to be better and PRIME95 reports no errors, but when I tried to edit some video, my machine froze up on me. Anybody got any suggestions on troubleshooting this dog?

Are you using the default timing? What is your current RAM speed? Run Memtest and Prime95 for 1/2 day.

My board sets the default voltage at 2.65V.

They are PC3200 KVR400 KIngston Value RAM. I have default everything for the settings. It's a Barton 2500 oc'ed to 3200. 200 mHz FSB and all that goes with it.

Update: The sticks are different physically - The China one has chips on one side of the PCB only, the USA one has chips on both sides of the stick. Methinks I need two of the same physical type.

Return the Chinese stick and get the USA stick. Also run one stick at a time and retest.

Roger that - I have gotten another USA stick and will try them separately and then together. The Chinese stick is probably heading back to whence it came.. :thumbsdown:

OK - I have 2 sticks of USA made KVR400 in Dual channel mode and PRIME95 gives me
errors

Run in Single CHannel mode i only get warnings (WTF? :confused

Contacted Kingston - This RAM is not supported: Sucky

I am going to try it in Sngle Channel mode with a voltage bump of 2.7

Looks like its all going back to the store - or fleabay...

You need to use Memtest86+ to check RAM. Prime95 is USUALLY used to test CPU. It will also work with RAM, but I find it less reliable unless you're running the RAM at the ragged-edge.

The link recommends DDR333. You have DDR400, which should be backward compatible.
