Serious problem with my Dual Channel RAMs

[Luciel]

Ok heres an example of an nforce user

My amd ASUS AK7NX8E-Deluxe motherboard (nForce 2) 2 Ram sticks of 512mb DDR400 each (Dual Channel). So in total 1024mb ram, when the pc starts, it says 1024mb memory running at 166mhz, ok correct me if im wrong, but i payed extra so it was ddr400 double channel so it did what it was meant to do, not for it to run at 166mhz, anything i can do about it?

I know its a risk, but have you updated the motherboard firmware?

Perhaps its a brand the motherboard doesnt like or know.

Is that the right model number for your mobo, should it be 'A7N8X-E Deluxe'?

What CPU have you got, not too hot on AMD but Intel has to have the CPU and memory at the same speeds.

ie PC3200 CPU 533 FSB, memory speed 333.
PC3200 CPU 800 FSB, memory speed 400.


Downloading th manual for the 'A7N8X-E Deluxe'.

Check if what your memory speed is set too in BIOS.
It can be set to 1:1, 1:2, 3:2, 4:5, 6:5 and a few more.
1:1 means that CPU fsb and memory speed will run at the same.
3:2 means that mem speed will be fsb*3 and CPU speed will be *2 or something like that.

Can't really remember how it was of the A7N8X Deluxe right now, but check the bios. There will be an option to set it. It might also be due to Automatic Options or something, set it to Advanced or User and change it.
That should do it, if that does not solve the problem take a look in the forums at www.nforcershq.com

You are right it's with the -E lol :P and the processor is an Athlon 2800+ XP

Ill go check the bio settings right now.

Ok, Kosmiq, i saw nothing like what you describe, HOWEVEr

I did find out that the processor is running at 166 and that i can set it to 200 however it wont start properly then (no video). The memory was set to equal the cpu, so i put it on manual and put it on 200mhz which is the higuest i could get (shouldnt it be 400?), and now when i start it says 200mhz, what are the implications of making a cpu that by default runs at 166, run at 200?

Basically your overclocking it a bit, not by much though.

Yep 2.8XP is 166 CPU frequency..

But direct memory accessing from the motherboard is 400mhz, but CPU to RAM will be 166. Less memory and the motherboard actually lets it to be 166.


Is your memory different brands Luciel?

Is one ECC and one non-ECC?
