Sub-10s @5040MHz with E6600 on P5B-DLX
CPU: E6600
FPO/BATCH: L709A436
RAM: Wintec AMPX PC2-8000 C5 (D9GKX)
MOBO: Asus P5B Deluxe rev C1, Vcore, Vdroop, Vdimm, Vmch mods
VCORE: 1.77v DMM
VMCH: 1.72v DMM
VDIMM: 2.64v DMM
OS: Win 2k3 Server
COOLING: "Grosse Bertha" 3-Stager
Here's my lowest CPU clock to get sub-10s... looking fast; really fast.
Another run at 5100MHz flat... 
I've tried a 2M at 5100MHz and got 24.573s or something but the FSB is very unstable there and didn't allow me to take screenshot. In fact, this CPU can't do 570FSB; I guess the wall is 569 at that temperature.
Thx to JP for all his unmeasurable help. And thx guys for reading.

@kemo: too expensive lol ; new intel generation will come this summer...
@misko: strap is modded here.  It wouldn't be funny to play with a 1066 strap mobo.

wow great I didn't know that Asus can go 560+ with 1066 strap. I was wondering when u said u want to to challenge me on 6600 , I said in mysef with Asus there is no way but if can pull such high fsb @1066 strap then it would be very interested to see it.

That's very interesting...
Now show us sub-10, sub-5 GHz, sub 50k pp all at once.

erm...its sorta custom made 3 stage cascade phase unit, no company makes it, you'd hafta contact someone to see if theyll make it for you and if not then you'd have to make it yourself.

Nice run before  .... I guess this is a faster board than the DFI if you went back to it? That cooling of yours is a beast, wonder what your electricity bill would be if you make it your 24/7 cooling hehe.....

hehe I'm pretty sure sub-10s is doable with a lowest CPU operating frequency; but with more timings adjustements. I've got some weird problems with my 2nd stage and didn't had the time to do more runs.

It isn't easy to explain really; these modifications involve machine language coding. BTW AFAIK someone might be working on an easy to use application to allow changes on the fly; just like you change timings with memtest.

It's an home-made phase change unit.

Difficult to say; my k type thermocouple is very bad and contact with evaporator was bad too.  Low side pressure was 0.1bar which corresponds to -135C with pure ethylene but much lower with an ethylene / methane mixture. BTW speedfan seems to be quite correct on this P5B-Dlx; @5.1GHz idle was -114C (-112C shortly after the runs) and load was about -105C.
Anyway, 2nd has some problems handling the load.

Not benching 24/7
I went back to P5B because speedfan gives some reasonably true temperatures while the DFI gives -128C idle which is hard to believe.

Well done Before but :
Write to precharge : 11=>9
Write to read : 10=>9
Maybe can you save 0.015s with it...

Yea; those L709A are very good clockers Too bad the first one has already been sold, it took 605FSB and should have been very good for benching under the cascade.

Exact It isn't the best one in term of FSB; could only takes about 570FSB under cascade. Anyway, that's fairly good.

Of course buddy, I didn't really tune the timings.

Don't know which value really helps stability; IIRC max actual Vmch should be 1.62v.
New Spi1M... boot @570FSB*9 with 1.84v
