Very Confused - Correct Settings?

avrc · 20 May 2007 at 13:52

I have Team Elite 2GB (2 x 1GB) DDR2 PC2-6400C5 800MHz Dual Channel Kit

On a Asrock ALiveSATA2-GLAN (Socket AM2) PCI-Express DDR2 Motherboard
It says: Supports Dual Channel DDRII800/667/533 , 4 x DIMM slots, with max. capacity up to 8GB

I noticed in the BIOS that each stick of ram was currently running at 200Mhz and saw that it gave me the option to change this to 400Mhz each.

From the sticky I gather that PC2-6400 does run at 200Mhz but it's 800Mhz effective? Not really sure what that means.

Does this mean I need to change it back in the BIOS to 200Mhz or is 400Mhz ok? Now that I have changed it, it's identifying them as DDRII800.

I'm very confused!

What does the Memory tab of CPU-Z say?

If it says 400mhz then it's running at 800mhz.

I don't use Windows, so can't use CPU-Z

Here are some BIOS pics though:

I've just had a quick skim through the manual and it says that the 400mhz option will run the memory at pc6400 speeds.

I've got the manual in front of me but couldn't find anything useful!

Looks like it's now set correctly then, thank you

Edit: Just noticed that the written manual says look at the PDF on the CD for detailed info.. doh.

Yea it's probably just a quick-start guide included in the box.

You can download the latest manual from the ASRock website.

It's ok, I found the CD.

Many thanks for your help.
