Asus P4P800 Deluxe Dual Channel Problem

[Brutis84]

I have a Asus P4P800 Deluxe MB (One of the first ones, i bought in 03). I have had it in dual channel mode ever since I bought it with 2x256mb corsair TWINX512-3200LLPT ram. I recently decided to upgrade to 2x512 corsair TWINX1024-3200C2PT ram. For some reason it decides not to boot with the new ram in dual channel mode, but will in single channel. Everything powers on, but no output to monitor, also there is no beeps from the motherboard. After it doesn?t boot and I swap the ram slots to single channel it comes back up and says ?Overclocking Failed!? although I never overclock.

Ive tried every combination of the sticks to get dual channel and can only get it with the old sticks. Also all the sticks work in single channel fine, so the new sticks aren?t bad. Things I have tried so far:
*Update BIOS
*Clear CMOS
*Specify Timings in BIOS
*Call ASUS Tech Support with no solution

TWINX512-3200LLPT
2-3-2-6

TWINX1024-3200C2PT
2-3-3-6

Any light on this situation would be appreciated; I might just break down and buy a new board so any recommendations on a new board would be appreciated too.

Below are system specs
P4 3.0ghz 800fsb
Asus P4P800 Deluxe
Seagate 80gb Sata
Seagate 160gb Sata
WD 160gb Pata
MSI Geforce 6600gt AGP
Thermaltake PurePower 480w PSU
Audigy 2 Platinum
Benq DW1640 16x DVD-RW
Leadtek WinFast TV Tuner

A new motherboard will be based on whether your video card is AGP or PCI-E. Which is it?

Hmm, did you try using the other 2 slots? Should be working, my P4P800 was a little picky about ram too, but never had trouble with corsair on it.

i swear on my life i did this during my rage of frustration and it didnt work. talked to corsair today and they told me to mess with voltage and whatever, still didnt work in first 2 DC slots, so i saw your post and moved it to 2nd 2 DC slots just to see if my specifying everything in bios made a difference on it and it worked. Still baffled on why it wont work in front 2 slots, but im happy regardless as long as it stays working.

Question, since i specified 2-3-3-6 in the bios for the twinx1024 ram, should I install the twinx512 ram as well even though it 2-3-2-6?

You can put in the other ram as well, it will run fine at 2-3-3-6, assuming the board doesn't get picky again, but doesnt' hurt to try.

Not sure why some slots work better than others, really makes no sense, but it's happened to me too. Actualy it's on another Asus board, P5LD2-VM, I have 2x512mb sticks of DDR-2. Doesn't want to work in slots 1 and 3, but it's fine in 2 and 4. It still posts in 1 & 3 just gets thousdands of memetest errors.
