First off this was copy and paste from our resident forums, here HOME SITE LOWYAT.NET (http://forum.lowyat.net/topic/481088)
and we stay at Malaysia WIKI of Malaysia (http://en.wikipedia.org/wiki/Malaysia) so the locations u c at the post u might not get...

Task: Extreme OC

1. E2610 Wall Barrier Breaking
2. E6600 Super PI Lowyat.NET Record Breaking
3. Gigabyte P35T-DQ6 PCMark05 Challenge

Participants Member: (TEAM KOC) coolice, irenic, sup3rfly, lolhalol, irangan , sanko
Location: lolhalol house
Date: 29/6 - 30/6

Recently a few of Lowyat.NET forumers who turned into close friends decided to form a small team just for the fun of OC. And finally Team K.O.C was formed with 8 team members currently, lead by coolice.

Last week, Shamino was kind enough to borrow us his DI/LN2 Pot for testing purposes. Therefore, we decided to perform a Extreme Cooling OC as soon as possible. In the beginning, we were not confident to perform a DI OC because we had none experience on it. Eventually, coolice decided to perform it using his DFI Infinity Dark and the adventure kicked-off.

The day started with coolice, irangan and sanko wondering around KL looking for DI insulation material. From Mid Valley to Subang, to Jalan Ipoh and finally we got all the stuff prepared.lolhalol assisted on getting some sources and we do the buying.

We reached lolhalol house around 7pm and immediately we started to setup the testing platform. So the Extreme OC commenced since then. At that time, irenic was still unavailable and told us he would be late for the event due to some personal affairs.

Once we reached lolhalol house, coolice was kinda worried that the DI would melt. Luckily lolhalol refrigerator was big enough to fit in all the DI. Then lolhalol and sanko were grumbling for dinner as all of us haven't settle for dinner yet. But coolice insisted to run the DI Benching first thinking the DI would melt. So there goes our dinner.

Look at the Shandy! It was 'Rock Solid Stable'

The first processor we tested was an E2160 which we bought it from rlhc17/raymond. Surely we do remember that the processor can be tuned up to 100% OC under WC. However, Extreme Cooling was not helpful. We couldn't bring it up any higher than we did before under coolice WC. So we were quite upset with the outcome.

Testbet 1

After testing the E2160, we were kinda down especially coolice. So we decided to go yamcha together before proceed to the second test. Immediately after having dinner, it was already around 11pm and we headed back to lolhalol house. sup3rfly went back home straight because working 7.30pm the next day.

The second test is on coolice's personal E6600. Everyone of us was hoping to break our own Lowyat.NET Super PI 1M record. Finger crossed.

During OC-ing coolice E6600, it was very very exciting. coolice was tweaking and at the same time worried about the DI. Both me and lolhalol job were to 'take care' of the setup so that nothing goes wrong. We were monitoring the DI while coolice was trying to tweak higher. The E6600 was easy reaching 4.6GHz. But we hunger for more.

Anyway, when coolice managed to OC to 4.62Ghz, his Super PI score already overtaken kcnyc's 11.359s with his 11.235s achievement.

4.620Ghz 512x9 1:1 4-4-4-9


After the 4.62Ghz achievement, we tried for 4.8Ghz but it couldn't boot. Then coolice try lower the clock speed to 4.7Ghz. It booted but it wasn't stable with all sort of errors like hang, blue screen and restart. However, after some tweaking, coolice manage to get a 4.703Ghz OC.

http://i143.photobucket.com/albums/r157/foojuan/11-3.jpg
4.703Ghz 522x9 1:1 4-4-4-9

After looking at the Super PI 1M score, we thought that we might as well break the sub 11 barrier for Lowyat.NET forum. So here goes.

http://i143.photobucket.com/albums/r157/foojuan/10-1.jpg
4.723Ghz 525x9 1:1 4-4-4-9

4.725Ghz 525x9 1:1 4-4-3-9 (Memset Tweaking)

Looking at coolice E6600 managed to hit 4.725Ghz, immediately we tried a PCMark05 run on 4.60Ghz clock speed and it PASSED. At that time, irenic was on his way coming to lolhalol house, bringing his Gigabyte P35T-DQ6 DDR3. At the mean time, i asked coolice to try 4.65Ghz on the DFI Infinity Dark to see whether it can pass PCMark05 or not. AND IT PASSED! On the DFI Infinity Dark!

Below is the link of the PCMark05 results. We were too excited and forgot to do a screen shot as we though we could do it on the Gigabyte P35T-DQ6 DDR3 later. Who had a legit PCMark05 can download the file below to check. After downloading it open your PCMark05 and right click on it. Choose option 'Open with Excel' or something like that. The details is all inside.

So we patiently wait for irenic to arrive to launch his Gigabyte P35T-DQ6 DDR3 under Dry Ice. Guess everyone knows why. For the Gigabyte OC Challenge of course! On the last day we had a chance to improve our score, why not!?

Once irenic arrived, coolice did the insulation on the Gigabyte P35T-DQ6 DDR3. It was not as easy as DFI Infinity Dark because of the huge chipset heatsink. coolice wasted around 2 hours for the insulation. Once everything was up and ready, we eagerly check the Gigabyte P35T-DQ6 DDR3 PC Health for Tempreture because DFI Infinity Dark couldn't read subzero temps. Check it out!

-71 Degree


At that time it was already 6AM in the morning and we don't have much DI left. So immediately we OC the Gigabyte P35T-DQ6 DDR3. To our shock it didn't even boot at 4.2Ghz. After doing some tweaking and changing the ram slot then we managed to get a 4.5Ghz OC. Then immediately we run PCMark05 but it keep on hangs. After an hour or so, the DI supply was all finished. Therefore we couldn't do anything but to stare among ourselves that we already tried our best. We thought that we couldn't at least do a 4.6Ghz PCMark05 to summit for the Gigabyte OC Challege. That's the sad ending for us and straight away we all 'fainted' in lolhalol house. irenic was the most comfortable one on the bed.

I want to kill this guy! Still can laugh after we fail to bench using a P35 Gigabyte Mobo for the Gigabyte Competition. How we wish that the DFI Inifinity Dark chipset can we switch to P35 chip and rebranded into Gigabyte!! Photoshop?!

Special Thanks to Shamino (VR-zone.com) for borrowing us the DI/LN2 Pot and all other K.O.C members for contributions.

[before]

Very nice work! :toast:

I love such long stories with pictures and screenshots.

[kayl]

nice guys :up:
But next time get pellet form dry ice will make benching easier ;)

[1Day]

Wonderful to read your post. Great benching guys well done.

[sup3rfly]

too bad i have to work on the saturday morning else i will be joining the fun >.<
plz let me know again when there is another session...perhaps the LN2 one... right now what we need is a copper pot as the one we were using is from mr shamino

[erwinz]

very nice guys.. :) hehehe.. congratz on getting your record.. :D

[hahanoclue]

pellet dice??? do u mean those small cubicle type???

[Harshal]

Good going Reggie & TEAM K.O.C.!
Very Good numbers there :)

[xt0m]

Nice go guys ;)

yes it is very cool to lisent to how it progressed and what problems you had :)
maybe you could give us some voltagees ?

Why dident you use Clockgen ;)

[Sanko]

aHH.... luckily the feedback here is kinda great. so i'll explain a little. K.O.C is just around 1 month old when we tried the 1st run for the DICE, we are total noob on DICE clocking. and actually the main purpose i just to try it out whether we would fried any hardwares or not. it's not meant for record breaking oc. but the results turn out not bad, so why not just posting it. for vcore, if i remember corretly, it's 1.65vcore. that's the highest we dare to try. furthermore, if it's not because of Shamino generousity borrowing us the DICE Pot, it wouldn't happen.

[Stapler]

You should try crushing up the dry ice into snow to make a slushy with the acetone. You'll have to constantly stir it to keep gas bubbles from forming on the base, but it gives a really ice result. I usually fill a few inches with snow, pour in about a shot of acetone and then fill up to the half way mark on my pot, which is about 3.5" from the base with snow and then just keep stirring it and pressing it down. Every once in a while I have to add more dry ice of course, but if you do this you'll hold really good temps under load.

[NightRaven]

anyway guys still read this and i still smile. nice knowing u guys :)

goob job and i hope to hear more from u all! :)

one day will visit ur forum also!

[Cupcake]

Take your dice and put it in a strong plastic bag and hit it with a hammer to get it like snow
