PC3200 RAM running at 166 MHz

[Wiley Q. Hacker]

Hi,

I have an ECS K8M800-M2 (1.0) motherboard running an Athlon 64 3000+ CPU.
The CPU's core frequency is 2000 MHz, with an FSB of 200 MHz. I've got the
latest BIOS revision (1.1A) installed.

I have 2 x 512 MB PC3200 DDR modules installed. For some reason, diagnostic
programs report that the memory is running at 166 MHz, not 200 MHz. I can't
seem to find any settings in the BIOS setup programs to be able to change
that.

Any pointers? Thanks.

Are you using onboard graphics? If so, on most boards the memory
defaults to 166.

What diagnostic programs?
Try CPU-Z, shows memory spec. You cam set manual memory speed in BIOS.

I did try CPU-Z. That's what told me the RAM was running at 166 MHz.

Thanks.

I am indeed using on-board graphics. So, that's probably what's causing the
issue. Is there a way around it?

Try putting your RAM modules in different sockets.

Hmm! I didn't know that!

i do not believe that's true, never seen this before. I am currently
verifying and so far zip nada zilch one way or the other. Status quo for
Conors outlandish statements, no way to check pro or con.

Does MB support FSB 200Mhz? Some ECS MB does not suppport FSB 200Mhz.

Read the ****ing manual for any nForce2 chipset mobo with onboard
graphics for a start.

Not really. It's a limitation of the chipset. Check your motherboard
manual, it should state it somewhere in there.

Seen it in a few manuals for nForce2 chipset motherboards.

After some RTFM, I found a table in the manual that says that if I have
2 DIMMs, both "double rank", then both the 1T and 2T speeds are maxed
at DDR333. In all other scenarios, 1 DIMM, 2 DIMMs where one is "single
rank", the max speed is DDR 400 for both 1T and 2T.

I guess this means that I have two "double rank" DIMMs. So, the
question is, what is "double rank", and how does a double rank DDR333
DIMM compare to a single rank DDR400 DIMM?

Comments?

Ignoring for the moment that his ECS K8M800-M2 uses the VIA K8M800 chipset,
how would he put his Athlon 64 3000+ CPU into an nForce2 motherboard?
