Air-cooled E6600 at 4054MHz

[sierra_bound]

CPU: Conroe E6600 Stepping 5
M/B: Asus P5W DH Deluxe
BIOS: 0078
VCore: 1.65v
Memory: Corsair 8000UL
Cooling: Tuniq Tower 120

This is the best I've managed with air cooling. I think it's okay.





Updated speed

Nice... so about 3900mHz 24/7 stable?

[sierra_bound]

Yeah, 3.9GHz is probably 24/7 stable. The newer BIOS's have helped. BTW, there are no mods to the board.

[principino1984]

nice score man!

do you think to use that vcore for the daily use?

Marco

[sierra_bound]

Thanks. No, I would not recommend 1.65v for daily use with air cooling. 1.575-1.6v is probably a better option. My CPU will do 4GHz with 1.6v and 3.9GHz with 1.55v. But it takes 1.65-1.66v to get those last MHz.

Ok, thats what I thought... I think the max to use in daily (under liquid or air cooling) is 1.55v real (1.6 from bios...). Am I right?

Anyway what's the stepping of you e6600?

Marco

ps. nice one u've got over there

[sierra_bound]

Yes, 1.55v would be good for everyday use. Even 1.6v is high.

If I set VCore to 1.6v in BIOS, AiBooster will read around 1.58v. Vdroop appears to be 0.02-0.03 under load.

thanx for your answers!

Hope to get my conroe up to yours

hmmm....4GHz on air...who would have thought

great work thought!!!

[thunderstruck!]

Can you how us the temps after full load? 1.55-6v? Just 10 minutes after 2x prime would suffice.

[sierra_bound]

I have not run dual Prime and probably won't because this is primarily a benching system. Running single SuperPi 32M at 1.6v, load temps, according to AiBooster, are in the low 40's. I'm using a Delta 120mm fan to help cool the RAM and the board. That probably helps lower the temp a few degrees. I imagine dual Prime would be in the 50's. But that's just a guess.

@ FCG - Thanks. How's your board doing?

[theteamaqua]

sweeet! im getting tower 120

[guess2098]

wooow! i save that $5

hahaha

very nice CPU

[sierra_bound]

LOL. Yes, you can keep the $5. Thanks.

[theteamaqua]

umm by new BIOS u mean 602?? cuz mine will arrive monday .. heh

i know that there are some

[sierra_bound]

i know that there are some

You misunderstood. I meant my board is not modded.

Sweet E6600, sierra. That ASUS P5W DH complements it very nicely for 450MHz @ 1066fsb bootstrap
Any better cooling any time soon?

[sierra_bound]

Thanks bachus. Probably will try single-stage cooling next weekend. The E6600 may be a better for air or water cooling. I don't know how much more I can raise the FSB given the fact that my board does not have Vmch mod.

Out of curiosity I decided to try dual-SP2004 with VCore at 1.6v. Under load, AiBooster was reading 58-59C. I'm sure it was probably higher than that. After ten minutes I decided I had enough of that. One of the disadvantages of using air cooling.

still find , one of the most overlooked , but fascinating results is this one :

http://www.xtremesystems.org/forums/...d.php?t=104484

same ram , same clock (+ 1 %) , same heatsink, E 6700

and a double ! pi 1M run.... 12.2


a 32M........12m 40


on a MSI 975 ....

E 6700 ..or rumours about better performance on msi and foxconn boards ? ..

[sierra_bound]

Yes, those are good times. But I was using XP SP2. He was using Server 2003 which is worth around 30 seconds in 32M. I was also running 4-4-4 timings because I was testing the FSB limits and wanted to eliminate memory as a factor. I will post some better results done with Server 2003 in the near future.

Here's an old result of mine done with XP SP2 and an E6700. Now subtract about 30 seconds from the time below and what do you get?

[mine]

thanks sierra for clearing this

my post was not meant to debase your results

they are really great in every aspect ....

[sierra_bound]

No offense taken. But the OS makes a big difference, especially in 32M. I've pretty much finished FSB testing, so now I can focus on other things, including getting better times.

[Duckmann]

Very sweet

[fredyama]

Awesome on air results, Sierra-san
