Ok, need a little guidance... - Tech Support Forums

I have got my new PC running...

M7NCD Pro
XP 2500+ Barton
512mb Geil Dual channel mem 400 mhz

When I first set it up, I believe my FSB was set at 133 mhz...

Which resulted in the CPU showing as an xp 1900+.

I brought it up to 166 and its now showing an xp 2500+... Which I have...

Now...Should the FSB match half of the mem??? 200mhz?

Right off the top of my head I cannot remember the multiplier is set at...

What are the correct settings for "normal"

My "goldfinger deviced" AMD was a little simpler than this

nowadays the bioses are so complex and featured that there are tons of options.

your fsb is 166.

But I am sure you can run the memory at whatever speed it will handle.

In other words if you have pc2100 also (called pc266) you need to run it at 133. The "Double" part of the ddr makes it 266.

If the memory is pc2700 (pc333) it runs at 166. That is the most natural match for your board.

Depending on the actual bios, if you have some pc3200 (pc400)ram you may also be able to run the memory at 200.

"Now...Should the FSB match half of the mem??? 200mhz?"

for the memory..YES...since I see that you have 400mhz ram...that corresponds to 200mhz for the memory.

So it all depends on the bios options....I was assuming in the previos post that the board has options to run the fsb and memory speeds "asyncronously" or "at different speeds"

So you would need 166fsb for the cpu and 200 for the ram.

Ahh.. I see...

Thanks...

The memory is PC3200..

I remember there is an option for running the memory "at spd"

A few more optimizations and I'll run my benchmarks again.

I was starting to worry about the memory, my original benchmarks weren't very impressing....decent... but not what I expected....

Now I see why...

John Prophet · November 21st, 2003, 04:19 PM

well yeah, if you are running the ram itself at 166 then it is underclocked quite a bit.

Of course memory "timings" are a whole other story..all those optimizations etc. Im clueless there, lol.

when it comes optimizations, do a google and find optimized defaults for your board, there arent many out there, but there is bound to be one. just writedown/print what it has and set it up in the bios, thats what i did with my Epox 8kha+

please forget what i just said... this had nothing to do with memory timings

If you're feeling adventerous you may try setting the FSB for your CPU to 200 and overclock your XP2500+ up to an XP3200+. Depends on your CPU cooler but the XP2500+ seems to take the overclock quite well in my experience. I've used the Biostar M7NCD (non-pro) and it's great for this simple overclock.

Yup, got it working good now...

Stock... for the moment..

Little tip for ya.

Running your memory clock and FSB speeds out of sync (i.e. 166FSB/200MHz memory) will actually give you WORSE benchmark scores and overall performance than running them both at 166MHz (333DDR). This all has to do with latencies between the memory clock and the FSB when they run out of sync.

Also, the stock multiplier for the 2500+ is 11 (11x166=1.83GHz)

If you want to optimize your system WITHOUT overclocking, then my recommendation is to run the memory and FSB clocks at 166/166.
