Asus P4C800e and Anand's Holy Grail 2

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 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 with 4DS dimms @ 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. Since I own one of these boards, this is an important issue to me. I am sure one or two other folks run the MB also... IF PATS is disabled past 800 FSB with all or some dimm configurations, I like to know....

Any hard insight into this issue.
thank you.
 
I remember reading this a while back that pats was disabled when overclocking. Do you know what bios version you are running? I wonder if that was corrected in a later bios update.
 
good question my man.
the board, and everything that goes with it is sitting on the floor next to me.
its my new years holiday project.
there have been a few bios updates, so maybe Asus has fixed the mix; we'll see.
Since I had not heard, I was asking.

I'll finish my project off with the latest from ASUS. Only problem is, right now I only own 2X256DS Dimms, so I will have no way of knowing. By nature I would be averse to buying two more just to see....:beer:. Ahh, impatience is a vice. What's the hurry. Right?
thanks.

good health and happiness for you and yours in 2004
have fun AND stay safe.....more:beer:.
