RAM Speeds

[opel80uk]

Hey guys and gals

I was just having a lookat my bios and I noticed that I'm running my 4 GB of RAM at 800Mhz. Should I be running it at 1066 and will it make a difference?

Thanks for your help!

By the way I've a Phenom II x4 955 BE and a Gigabyte MA770-UD3 revision 2 board

From Gigabyte
"Due to AMD AM3/ AM2+ CPU limitation, memory module of DDR2 1066 or above speed is only supported by 1 dimm per channel."

You don't really need to run at 1066 so keep it as it is.

Thanks for the reply!

So basically it means that there isn't any benefit in running it at 1066?

I'm saying theirs no benefit that's not what the limitation is.

Well that's sorted that out. Thanks for your help Legacy.

Check the CAS settings for the lower speed, you should be able to tighten it over the cas settings for 1066 which would give a small boost.

Use CPU-Z to check cas settings at the different speed rateings for your memory

Hey Pob, how would I go about doing that?

Also Sorry if I am being thick, but as I am running 2x 2GB of RAM, would I not be able to just place them in separate channels and run them at 1066? Would it make a difference?

Thanks again as always.

you have to adjust the cas setting through the bios.

what make and model is the ram?
