2x1GB wont run at DDR400

[Lanz]

I upgraded the memory a while ago on my old GA-K8N51GMF S754 System (A64 3400, Nforce 6100 chipset) - Only now Ive noticed its running at DDR333 and it wont goto DDR400. When i take out a Dimm, and only use one, it works fine, I've swapped them around and still no luck.

It used to work fine with 1x1GB and 1x512MB, but changed them and bought a matched pair of 1GB.

I have no RAM speed option in the bios and i've got the latest bios.

These are standard Crucial PC3200 dimms, so pretty popular and I would have thought 100% supported.

Ah, that did it. I set it manually and it works.
I never knew about ctrl-f1 , I just thought this board had crappy overclocking options.

Thanks.

Well thats what originally thought, but I remembered it was only 2 dimms it supports, and if you used 4, then it would bugger up and go down to 333mhz.

It says in the specs it runs 2x1GB dimms at 400mhz, and Im sure many others are.

Well I set it to 400mhz, T1 manuually before i went out this morning, and it worked ok, i'll have to test it properly tonight.
