P4C & Centerwood Board in single channel

[-=TriX=-]

Specs:

Intel P4C 2.4ghz
Epox 4PCA3+ rev 2
2x256MB BH-5 RAM
Radeon 9700

Question:

There is a problem with the epox motherboard and for some strange reason it will not run dual channel..only single channel. I've tried a billion things to attetmpt to fix htis, but nothing successful. And frankly I don't want to waste any more time trying to make it run DC.

But I can still run single channel and w/ high vdimm and this BH-5 some tight timings and maybe ~250. I was wondering if anyone could point me the direction of some information that would show the performance difference on a centerwood board between single channel and dual channel. Unfortunately, I havent been able to find anything via search on this and other forums nor thorugh google.

Any relevant information appreciated

Well, you will lose nearly half your memory bandwidth compared to dual channel.

I realize that, running single channel will only be a temporary solution. I was just wondering how much overall performance (esp in 3d/games) would decrease compared to dual channel mode.

Running in dual channel will net you about a 3-5% performance gain in 3D gaming. So you'll lose about that much if you're going from dual to single channel.

Really? I rhought it would be significantly more than that. Thanks for the info

Increasing memory speed has very little impact on overall system performance when compared to increasing CPU speed.

Check this article out for more info: http://overclockers.com/articles758/

A quote:

"The biggest myth in this community is that: Memory Matters Much. Some people think it matters as much or more than CPU speed.

It doesn't. It never has and it never will. That's a urban legend.

This doesn't mean it doesn't matter at all, it's just that increases in memory speed scale little in overall performance compared to CPU speed.

As two very rough general rules of thumb, a 10% increase in CPU speed will get you about a 6% improvement in overall system performance. A 10% improvement in memory speed will get you about a 1% increase in overall system performance. "

good article and Interesting results there

just a stoopid question, what memory sockets are you populating ? 1 - 2 or 1 - 3 ?

Correct answer should be 1-3 So hopefully thats where your "doing wrong" and what will get you back up..
(Im probobly stating the obviues but...)

Best of luck.
B!

Mr. B

Yeah I tried both DIMMS 1 and 3 and DIMMS 2 and 4. It actually turned out to be a RAM problem, one of the sticks had two defective addresses
