P4C800E-D; the Grail Part 2; PATS disabled in OC

[user1]

In the Grail 2 Article, the author states: "The fastest configuration should be 4 Double-Bank DIMMs on the Intel 875 chipset motherboard. Our first efforts to test this configuration, with 4 x 256 DS OCZ 3700 GOLD modules did not show 4 DS DIMMs any faster than 2 DS DIMMs on the ASUS P4C800-E. This was a real puzzle considering that other predicted configurations were easily verified with Quake3, Super PI and other benchmarks. When we looked deeper, the problem became clear. In every configuration that we had tested with the ASUS P4C800-E, the Performance Mode showed ?enabled? but with 4 DS DIMMs at any FSB speed faster than 800, CPU-Z 1.18C shows Performance Mode ?disabled?. Our trial was failing here because we were comparing 2 DS DIMMs with PAT on to 4 DS DIMMs with PAT off. We have asked ASUS for the reason behind why PAT appears to be disabled at 4 DS DIMMs above 800FSB."

I have searced but did not find... Does anyone KNOW if ASUS has ever responded to the question about PATS appearing to be disabled while running 4 DS DIMMs above 800FSB on the P4C800e-Deluxe ?? The Grail article indicates PATS is not disabled @ 800FSB. The article also seems to imply that PATS is NOT disabled with any other memory configuartion other than 4 DS DIMMS. BUT, as far as I can tell, Grail 2 does NOT come right out and say that. Suppose PATS is disabled with any or all dimm configurations once you bump the FSB past 800, eg 1000.

Any hard insight into this issue.
thank you.

Asus makes a P4c880-E ?

You're a real hoot SANTA. No actual knowledge on the matter huh....
That's okay, go back to your X-Mas Cheer; poundin the pud, feeling the rub. :lips:

Amused really does have alot of good knowledge to offer on these boards most of the time so I had to LMAO at your response to him

BTW, I have a P4C800-E with 2 DIMM slots filled and sitting at 900FSB. PAT is indicated as enabled in the BIOS, Sandra and CPU-Z v1.20a.

I haven't tested it with all 4 filled. All this pud pounding and rubbing is taking up too much of my time.

thanks Santa,
Hope you had a good x-Mas. Den you be in da same boat as me captain. The question remains; Anand's tests in Grail 2 showed the PC4C800e-deluxe disables PAT when Double-Sided DIMMS are used in ALL four Dimm slots AND the FSB is running more than 800Mhz. Kinda limits one's choices. As stated, the Grail 2 Report passed the findings to Asus and asked for a reply.... To DATE, no post from Anand on any reply or fix from Asus.

I realize things move off the bench very fast these days, but the Asus P4C800-e is a popular board. IT would be nice to have some further valid informaton about this issue...... :beer:
