Today, I've become a believer with Heatkiller rev 3.0

I've dumped my Fuzion V2 for a Heatkiller 3.0 and the results were quite shocking.
If you wanna shave even a few more C off, using Indigo Xtreme beats any other thermal paste.
Both products are like miracles when combined: A 10C difference at full load is insane.

Well from what I read, your batch should be good for overclocking. I understand your frustration on wanting to get your vcore lower to keep the cpu cool under pressure. We all want that. There are no secrets, just some are luckier than others.

As for my settings, they are nothing out of the ordinary, in fact the Asus P6T is easy to set up as only a few settings are needed to be changed. I'm just lucky to run my chip @1.28 for 4.2 or 1.375/1.39 for 4.5. I say 1.39 because I'm finding it needs it for stress testing 100% stablilty on all threads (and I'm only do for this thread I created to show temps on the HK for several hours on Prime95 on all threads). I can go 1.375 for every day normal 24/7 use and that includes heavy gaming. Again, luck of the draw. But to me, as nice as it would be to have low vcore, I was more interested in what to do to keep the cpu cool. If I have to bring the vcore up to overclock some more, I don't worry about it, its what's acceptable to me on load temps. Anything below 90c made me happy. That's why when the GTZ reaching above that mark in just 5 min. of LinX made me think twice about taking a chance with the HK3. This is why I will never go back to Air cooling for my system anymore, you just don't get the results as you do with a proper setup of liquid cooling. I know some will probably debate this, but it's just my preference.

Back to the P6T. The only thing I maybe different from your own mainboard is that I have installed the 0006 bios for P6T deluxe V1. It was a bios that fixes the turbo throttling issue when you use the x21 multiplier. Sure you can use it premanently for your overclock, the drawback was more than likely when you add a load to the cpu, it would throttle back to x20 multiplier. I've even tested this myself, and sure enough mine did, so overclocking with that multiplier wasn't accurate. I have changed that now with this bios even thought its for the V1, it will work on the V2 with some bios flash commands. So far to my knowledge, no V2 bios update will do this yet.

Now as for my settings, the only thing besides changing the Vcore, I have adjusted my PLL value between 1.90 to 1.96 and the QPI/DRAM between 1.30 to 1.35 depending on how high I go on the overclock. I also made sure I selected the speed of my Ram and not use auto (and of course set the ram volts at 1.66). I have also disabled any throttling options on the cpu under advanced settings and made sure the speedstep (turbo and throttling) are disable.The only disappointing thing about this board is that it becomes unstable after the 218 on BCLK. I could probably push this cpu more, but the mainboard wont let me. Of course I'm using 12 gigs of Ram, so that might have something to do with. Either way, I'm more than happy to reach the 4.5 mark and with satisfactory temps with my HK3.

That's some interesting stuff you mention. Looks to be tedious to install from what I have read so far, but if it improves temps, I'm all for it. I will have to do some more research on it. Where did you get your stuff from and how much?

[ontariotl]

Here is a longer load test with Prime95 all 8 threads and In place FFT's tourture test. Not exactly 8 or 12 hours, but probably enough to show the long term temps as you can see it hit the ceiling pretty early on according to Realtemp. I didnt want to leave it for 12 hours since my room is not temperature controlled and changes ambient temps too often. In the four and a half hours it stayed at 24c.
Also note I have bumped up the vcore a little to 1.39v to make sure it runs stable through stress testing. 24/7 usage I can go 1.375v.

Here are the results.



So compared to the quick 5 minute test with 1.38v, its not too far off of 6c (plus another 2c for 2c less ambient from the first test) each core even at a higher slightly higher vcore. I hate to find out what the GTZ would have been if it was already at 92c 5 mins. in and only 1.38v.

I am interested in this Indigo Xtreme though, maybe I could get a few more degrees dropped with this stuff. Too bad no Cdn distributor.

They only charged me $8 to USPS ship it to Canada, and I didn't have to pay any taxes either.

(The value is $19.99 USD so you may or may not have to as its borderline, I think they mark as Commercial Sample)

I think its worth it, especially if you have a HeatKiller 3.0. If one is about to spend $20 USD on TMI though I would expect them to already have the best water block on the market, as the temp drop from the IX alone will make you want to buy one for a huge drop further.

I did some reading about this stuff and it sounds very interesting and tempting to try. With the money I invested to get the best of of the equipment, what's an extra 20 bucks? Apparently to some, it seems like its too rich for their blood which doesn't make sense since its probably the cheapest item on their shopping list for cooling the cpu.

The thing is, it's $10 a pop (you get two in a box), not $10 for a tube or something. How often do you do something that requires you to re-seat your CPU water block? You'll blow $10 every time you do.

If you want to do a before and after comparison, you'd better be organized and scientific about it from the get go because the stuff is too expensive to just dilly dally with switching back and forth.

Also, after testing it I had a bitch of a time getting the stuff off my water block and CPU. It did NOT just peel off nor scrape off with a credit card nor did Acetone get it off.

A TIM like MX-2 is an absolute pleasure to use by comparison.

I was so close to pulling the trigger on this tonight. I bought a bunch of compression fittings instead. While the numbers are impressive, I don't believe it is worth the money to upgrade from a dtek fuzion

[miggs78]

Good call Phobes.. besides if you do want to upgrade get a Fuzion V2 instead, the pro mount which is stock on it actually does help temps, and supposedively it also manages temps, your quads a hot running processor..

On topic, nice cloking there ontario.. :)
