this 12.531s was the best i could get with 9x multi, no matter 1:1 or 4:5 the result was the same, except 1:1 @ 1066 strap have more chance to get 12.531s. i'll try 8x500 1:1 @ 1066 later on.

Cool :)

Do you remember doing anything different before the run? Like getting a cup of coffee and letting it sit there for awhile or something?

Lol, yeah i drink coke and pray first before hit OK.....
anyway, i run 1m on 3.6 challenge got 13.890s (beat kunnak by 0.001s) but the available memory wasnt the same.... dont know why.

my little quad core made it to equal 10th place huh :)

At default 9x multiplier we have Q6600 @9x443FSB via setFSB :cool:

Now this I consider fast considering Kentsfield quad core B3 stepping is slower than core2 duo B2 stepping for Super Pi!

yeah P35 chip works properly with 4:5 ratio as per my testing :)

Heres my E6700, I have only had about an hour with it, but here is what I have got so far. This is using a thermalright 120 extreme. I may be keeping my E6600 over this, I'm not sure yet, have to mess with it more to see if I can get a high enough stable clock, to justify keeping it over the E6600.

hey coop nice going

try running that quad GT 1:1 with supertight timings......they seem to like that :)

and what maxmem are you using

you also should run 1M for about 10 times on each timings change and record the quickest one........i've been lazy with my run.........just set my previously tight timings and ran for a few times and get 531s and a couple of 516s

my RAM is not stable at those settings so i need to get a mobo with reliable voltage regulation on RAM at feed it 2.6v and really tighten things properly and go sub 12.5 which is possible :)

I still need to use divider after awhile to be able to keep up. I was happy to see 600. It booted up @ 616. I've been busy over at low clock. maxmem 600.

eva: 43+ sec., wow. Did you try other timings by chance, like 5-4-4-5? Thanks for showing both.

EDIT: nevermind, it was slower. I was so intrigued by what you did with Cas5 I ran some myself. I still think 2-2-2-5 so when I see results like yours I'm always amazed. I have my 6600 in the board now so I could not run 2/3. I did 9x444 with 4/5 and came up with this.

strange on P5B Deluxe same ram can do 5-4-4-4 @600Mhz on Asus Commando with 1001 bios only 5-5-4-x and I thought commando clocked ram better than P5B Deluxe ? :(

Not Top10 but it's my first try with 4MB cache on air (previous was E6700 directly on cascade ;)) - 12.593s with E6750 500x8 1:1 4-4-4-4 on Commando, modded 1333 strap (CPU was going for DI ;) but NB was aircooled all the time so no genuine 1066 strap possible, unfortunately):

Hey I'm just wondering, what OS is best for PI benching? Until now I've been using a stripped XP SP2 but someones telling me 2003 Server is better..? Could someone help me out? :p:

server 03 always appears much faster to me. I don't know how to "strip" XP or anything though.

Make a note of what get's loaded in Safe mode and then remove all multimedia and other crap using nLite. I tried this, but since I actually needed the MM stuff a patchwork copy this and that dll didn't work..in other words, it was completely fubar'ed. :D
