Troubles P4C800Deluxe(I875) fixed with TCCD mem.

[Gamer]

got troubles using these modules (Gskill) with P4C800 Deluxe.
betabios 1009d.001 fixed them.
couldn't even boot @ 233x15, now I'm on 267x15 stable as hell

biosupdates

non deluxe version and others can be found here

i have some problems to go highter than 260mhz fsb in 1:1 whith every ram and bio 1016, now i try this one on my P4C800 DELUXE V2.00 and i will told you how it goes....see you later

How does this bios perform compared to the older ones?
I have the P4C800-E, but spotted a beta bios on ASUS' site, dated 10/14/04. Still using bios 1014 now.

[Gamer]

good I must say.
always used the 1016 for over a year.
no performance loss, PAT enabled, 2.65vdimm, vcore is more stable then before, same results with Sisoft, benchmarks,..... (not noticeable).
had some A64 setups, only I can't bare it to sell this setup, bought it in May last year.
still going strong with my same old PIV3.0C (my best was 2 months with one setup :p).

why no one is aware this ?
Some said "I think Gxxxxx TCCD sucks with 875 chipset"
Well...What can I say?

I am doing dual channel 267fsb 2.5-3-3-8 2.75v p4c800d pcb 1.02. Ther are ADATA566 512mb new red pcb a pair of TCCD 434 & other pair of TCCD 431, all memtest extend test stable. Using both bios 1017 & 1019.01 didn't experience any problem.

Maybe TCCD's are suck at CL3 with i875p at high fsb, they don't like CL3, all get errors in memtest#5.

I tested with both ASUS P4C800D & Epox 4PCA3+, using 8 sticks 512mb TCCD one at a time, all CL3-4-4-8 DDR566 got errors in memtest#5 or #8.

But they love CL2.5-4-4-8 , so is 875p don't like CL3 at high fsb ?

I just finished testing my 1GB kit of GSkill PC4400 2.5-3-3-7 with the 808 PCB. I'm using a P4C800-E Deluxe rev.2 with the 1017 BIOS. The 2.4c is cooled by the a lapped stock Intel heatsink in a 19c ambient room. I know its not cpu limited because I was running SuperPi 1M's at 300MHz 5:4 with OCZ PC4400.

275MHz is a no-go at 2.5-3-3-7, but runs stable enough for a Sandra mem bench and Photoshop editing at 2.5-4-3-7. Vdimm is 2.75v...2.85v did not help.



Setting the timings to 3-4-4-8 only gained about 5MHz. I really hope a BIOS update corrects this problem.

BTW - Why are the cpu-z checksums different?

[leotonch]

I don't know it is a bios problem or else. But I would think the difference btw 1017 & 1019 will be the CPU lock free function.

I can go 275fsb cl2.5-3-3-8 but not stable to complete benchmarks
We might need high quality i875p or better cooling for the north bridge running 1:1 at such timing. Remember that 1/2 of your Vdimm will be the VTT of the north bridge. So higher voltage will heat up more the nb too. For my CPU, it shouldn't be a problem cause mine's 2.4c were tested prime95 48hrs ok at 3.4g default voltage

Is there anyone water cool the nb or with a new bios, and get better result ?

[Gogeta]

Its definitely not NB cooling...its just the weird reaction TCCD has with the 875P chipset. I'm pretty fed up with this setup...itchin' for an A64.

[leotonch]

Unfortunately, my abit Av8 didn't good enough to do 275fsb cl2.5-3-3-8 due to acp/pci lock problem. I can't test the limit & quality of my tccds.
Waiting for nforce4.....

Just 271fsb on i875....

[jagare]

Yeah me too, best I can get with my PQI TCCD stable is 275MHz with 2.5-4-3-7 timings. It looks like the TCCD chips run quite a bit better on a AMD setup. Now I'm itchin for a 3200+ s939 + MSI Neo2 Plat.
