LN2 + Retail E6600 = 5.15GHz Benchable

While I was driving home yesterday I desided to pay a visit to my LN2 supplier which was located nearby. I left the place with a 20L can filled with LN2, naturally :D

This morning (while suffering of a massive hang over) I bolted all of the parts together and started to test the "new" container. To be exact the container is not new I just haven´t tested it with LN2 yet.

Well the container exeeded all of the expetations and the system ran perfectly for six hours.

The few first hours went while struggling with the P5B Deluxe motherboard which wasn´t working properly. Even for a slow strap the motherboard was definitely much more slower than it should have been.

It seems that Asus has done some changes in bios 0903 for better FSB overclockability. 0903 bios is ridicilously slow when booting with 533FSB+ speeds and it didn´t seem to gain anything in FSB overclockability. However with 0903 bios when booting with 333FSB+ the board can reach 15MHz - 20MHz higher bus speeds than with the previous bios releases.

After flashing in bios 0614 the performance raised back to normal.

Since the CPU can do 5.15GHz with only 1.53V at -120c, it is clear that the board is the bottle neck.

Chipset already 2V, I guess the only way is to DI/LN2 on chipset to get 9x600+ :D

wow! pretty sick, Stilt :up:

You guys are all head-to-head there in SPi 1M (E6600) Ranking on Hwbot! Do you think you can take the crown in SPi 32M, though?
Grats and good luck, man :toast:

5.1Ghz + @ 1.53v, thats a nice chip. You need a board that can do 650 ;)

Wow, way to pwn that SuperPI there.

Excellent. Stepping?

wow just awesome this CPU 1.53V @5.15 gig is just :slobber: :slobber: :slobber:
Hope you can get a better board with FSB 600+ and do some more - this chip seems to be one of the best around.

(why somebody can't find a multi-wire mod like back in xp days...live could be so easy then :D)

hey

need boards capable of more fsb..this conroes are freak..:banana:

Nice rig, I'm preparing almost the same rig for a LN2 run. I know the chip will do 5,1Ghz easy. We all need better boards.

did you try raising the Vcore ?
1.53V can be just not enough for 5.GHz+

Nice! Would this beat that 7.2ghz P4 in a synthetic benchmark? (If LN2 wasn't required)

Do you think The Stilt didn't test that :confused: :p:

I did the VFSB mod and tried to cool the MCH with LN2, but neither helped.
It seems that P965 (at least this invidual) has a cold bug at -15c. Down to -10c the board worked just fine, but when the temperature was lowered to -15c the board simply stopped.

Frankly, it is quite hard to keep the temperature at -10c with LN2 :D

Tried up to 1.7V, made no difference.
The one and only thing this chip needs is few additional multipliers ;)

Thats pretty fast. Too bad for the cold problems.

ps. oliko tuo se yks protokuppi?

Sama laitos.
Kuppi on jopa hieman liian tehokas uusille prossuille :D

Wait till it gets -30C in Finland, will add a few more Mhz :D

Excellent :) Exactly the same problems i had with mine... I tried to cooled the chipset with ln2 too but nothing happend. And from cascade to ln2 i didnt gain anything. :(
