E6700 on Vapochill LS "Jinu Mod"

[dominick32]

CPU: Intel Core 2 Duo E6700 Retail (L627A)
Mainboard: ASUS P5B-Deluxe (Vcore,VFSB Moded)
Memory: OCZ Titanium Alpha VX2 PC2-8000
VGA: ATI X1900XT
HDD: WD Raptor 150 X 2 in Raid 0
Power: Silverstone ST56ZF
CPU Cooler: Vapochill LS "Jin Mod"

Vcore : 1.70V
Vdimm : 2.30V
VMCH : 1.35V

Jins Vapo is awesome but my exhaust fan on the unit is not functioning so I am currently having problems with the Vapo holding any heat. Forget about load.

Right off the bat bios are reporting temps of -45*C at 1.4vcore, where my stock vapo only produced -25.5*C.. So the gains are apparent, I am just having some heat issues (i believe with that rear exhaust fan)

I will keep everyone posted.

I will let you know however that the chip booted up right into Windows and passed a few minutes of Spi32m @ 4ghz 1.65vcore. I will post the screenshot:

I hope everything gets figured out tonight.



UPDATE!!

4.4 Ghz @ 1.65 Vcore .....



Here are some frosty pics. Unit still not holding load at all... I am trying to get in touch with Jinu.... I tried testing fan outside of the case. It works. Only when plugged into Vapo controls it doesnt work. My next test will be using the vapo with an external rear fan powered by the external PSU....
As you can see. The Vapo produces a frosty -60*C unloaded (with no heat) and -73*C on the LCD. So our vapo LCD is skewed about 13 degrees but it looks cool... lol

I am still very dissapointed right now because for the first 15 minutes of operation everything was great. but after the unit got warm it stopped taking any load at all. Even at stock vcore 1.35 where I sit right now its a -25*C evap LCD and it occasionally starts dropping. Its kind of scary.....



UPDATE!!!
FIXED!!!!!

I just got off the phone with Jin. It turns out my rear exhaust fan could have been damaged in shipment. So I simply replaced the fan with a extra 75cfm that I had lying around and bang. She starts working beautifully again....

UPDATE 10:59PM

4.46 Ghz @ 1.65vcore



First results are not that promising.
Exactly 1.70 vcore - 4.49 Ghz , At 4.5 Ghz it fails SPi1m:bang head
I really dont know if I feel safe pumping more voltage into it??
Epox and Maji, bios CPU idle temps @

1.35vcore 3.0ghz = -50*C
1.40 vcore 3.4ghz = -45*C
1.65vcore 4.0ghz = -30*C
1.70vcore 4.0ghz = -24*C



Also something else interesting: Did you ever see a Vapochill LCD get such a cold temperature reading it failed?

Maximum temperature on the Vapo LCD is -73*C, anycolder and it does this:



Please note: Do not trust the accuracy of the Vapo LCD, at idle the temperatures are from 10 to 15 degrees off.

UPDATE 4:04AM

Did it! Finally broke 4.5 ghz...

4.51 Ghz @ 1.72 vcore



UDPATE 4:29AM

This chip is a clocker ladies and gentleman:
4.56 Ghz @ 1.72 vcore



UPDATE
1.80 vcore

4.62 Ghz, also started to tweak FSB/MCH voltage for the first time to prevent chipset instability. So far, so good.


A little update for today. Tried for 4.2 Ghz @ 1.6 vcore last night and it failed 25 minutes in to Dual Prime95.... :bang head I checked the socket at time of failure and what do you know? Condensation all around it. So, I took this time to remount the Vapo, re-apply Di-Electric grease in and around the socket, and finally get a tighter remount with a new cover of Ceramique...

Check here:


Since I had the whole mobo apart again I decided to install a new Swiftech chipset sink/fan as well. It seemed to lower my temps 2 to 3 degrees from stock.



I will keep everyone posted on new 24/7 stability points as well as a possible shot at benching for clockspeed again.

Cheers.

Looking good so far guys. "knock on wood"
Just about 45 minutes dual priming @ 4.2 Ghz 1.65vcore!
I was also able to get a 4.7 Ghz validation but no Spi1m after the remount.. :beer:



Got a 4.71 Ghz validation screenshot:




Maximum Spi1m so far is 4.65Ghz. Almost a 10 second slip:




At 1.65vcore the maximum benchable is around 4.49Ghz. I think the chip is stumped right there until I give it a tad more vcore. But it seems to be scaling well with voltage. I just got another max clock tonight 4.8Ghz which I didnt validate.

Its looking pretty good. I tried a SuperPi1m @ 4.71 GHz and it crashed because of heat. Oh well. I'm working!

Here is just a little example of well Jins unit is holding under EXTREME heat load. My actual vcore voltage was 1.86volts and Jins unit held CPU idle temp to -14*C. Compared to typical single stages that would cringe at this vcore, producing more like -5*C in the bios.
