P4C800 Memory Timings

I have the P4C800 Deluxe, P4 2.4 GHz @ 3.0GHz
Corsair TWINX512-3200LL ram @2-2-2-5
ATI Radeon 9700 Pro
Haven't tested this setup for too long yet... it's only been a couple weeks, but it seems stable so far.

RE:

Great!
Could you please post all the settings from the "Chipset" configuration menu.

Also, which BIOS version and which OS are you running..

Thank You.

Got the mem timings to work as desired (almost)..

Got timings of 2-2-3-5.. Could not achieve 2-2-2-5 as pointed out by Jonnyquong.

Happy with they system and the benchmarks.

I have the same Mobo and 2Gigs of the same RAM.
My settings are at 2-2-3-5 too.

I changed them to 2-2-2-5 and I get a overclock boot failure.

This might be because the Corsair RAM is not on the ASUS compatibilty list on their website?

Perhaps you've missed an older thread in which the CORSAIR is discussed.

I have my settings as
Jonnyquong has posted in this thread with the exception of the Graphics Adapter Size value; but that is not relevant.

What I do want to get at is that I've had to increase the memory voltage setting to 2.75v . I did it incrementally with a round of memtest86 at every step. I found no errors reported when I reached 2.75v. That is how I've gotten the P4C800 Dlx to work stably with the CORSAIR low latency 1 GB twin pack memory.

RE:

I did not increase the voltage to the memory in my setup. Don't think its worth providing much juice to get better by 1 clock that too over RAS# to CAS# Delay.

Thanks for your input.

Also, has anyone tried memory bandwidths on their setups using Sandra? I achieve 4660Mb/s and 4658Mb/s for Int and FP.

Is Sandra freely available?
I found this article on the net making use of it. In their setup the Corsair was used. Take note of the DIMM voltage @ 2.77...

You raise a good point, however, that the 2-2-2-5 may not be much better than 2-2-3-5. I am still working out a lack of sound for which I believe a better PS is needed, but when I get a chance I will try a freely available benchmark with the two memory timings above and let you know.

Hello,

I'll check my memory voltage tonight and get back to you on my settings.

Thanks for all the help too!

Egv,

It is a freeware. Thankfully.

Hello,

My RAM Voltage is set to Auto.

My CAS setting are presently 2-2-3-5

Rich,
Did you get a chance to run memtest86 ?
Do you have signs of system instability with those settings?

Hello,

No I havent run any memory tests.
No problems at all.
I love this board!!!

I have the same BIOS settings as Jonnyquong and 1GB of Corsair PC3200 TwinX-LL. System seems to be running stable with no issues. I did notice that the memory is running at 320MHz instead of 400MHz though. I guess it really doesn't matter though since the performace is much better with the custom BIOS settings than it is with the default. My memory benchmark scores in SisSoft went from 3900ish with the default settings to 4250ish with the custom settings. That's about a 10% speed boost so I'm happy.
