Ram/Motherboard compatibility help needed

[fish99]

Hi,

I'm trying to find out whether my ram - 1 GB Twinmos DDR400 (PC3200) Dual Channel Kit (non-ECC, 32Mx8(x16) ) is likely to work with a board I'm considering buying - the Asrock 775Twins-HDTV R2.0.

I contacted Asrock and they couldn't give me a definite yes/no answer. What they said was-

When choosing memory for our motherboards you just have to make sure that the modules are non-ECC, unbuffered and not high density.

I honestly don't know whether the ram is unbuffered or high density. Could someone who knows more about ram than me have a look at the Twinmos specs here and see if they can figure it out-

Thanks a million
