5970 great overclock thanks to overclock.net

post #1 of 26
Thread Starter 
I would like to thank overclock.net for how it has been very helpful to so many persons who were or are ignorant to the different aspects of the computer world. I am not really one such person as I do deal with the computers daily whether building, repairs hardware/os. But everyone still see something at some point that’s bigger than they are and I am no exception. This is where overclock.net comes in. This site is truly professional and as such I really want to say a huge thanks for me and from the many grateful folks who have turn to this site for help and was helped. I have seen other sites where people are looking for help and those who are of that site(s) go about bashing or undermining those in need . Immature at best is what such behaviors are, but not at this site.
As such I hope for the best for the owner(s) of this site and encourage you and these great members to continue in your splendid work as it means a lot those (myself included), when a challenge(s) is able to be overcome, thanks .

I can truly say that I have found a whole lot of insightful information that has helped me solved a tough head scratcher. Now pertaining to one such challenge that I mentioned, my 5970 card. I thought it was faulty when I couldn’t get it to overclock pass 800 core and 1000 memory speed s. Now sadly, due to the lack of tech savvy on the part of my graphics card manufacturer, their tech advice more or less saw to the purchasing two different psus’ apart from the 750 watts that I had. I got an 850 watts and finally an 1100 watt. They kept insisting that the psu wasn’t able to diver the card. Each time I contacted them for help, I was basically told that the card needed a better psu for they had concluded that the gpu temps were good and heard nothing from me that implied that the card itself was faulty .
I gave up calling and gave up overclocking the card, until recently when I saw some info here at the grate overclock.net that sparked my curiosity . I sent a message to a person named ‘Verbatim’ here at this site who pointed me in the right direction (thanks a lot V) . Upon following his instructions I ended up reseaching info that was listed here @ the OC.N. It was then that I was able to finally overclock my card and get some terrific results .
I decided that it was only appropriate to share what I have learned here so here goes.

It turn out that it was the vrms that were getting hot. Overclocks that were over 800 mhz saw the vrms reaching temps over 120'c so i had to fix that. Initially i had no idea what vrm were or what they did, but as i said Overclock.net quickly provided the info and how to deal with it.
I had used the thermal pads that came with my waterblock but they weren't doing a good job with me getting these kind of temps. I decided to remove them and try a different method as seen in the pictures below.

I used some double side adhesive to create a wall around the vrm, then i used that thermal paste over the vrms. I figured that by the time the ce'ramique was dry i would be getting some good temps.
Well after a week the temps were better but not great. My temps did come down from 120+'c to 95'c with the same overclock i had with room temp being 76'f/24.4'c but i still wasn't pleased. The picture above shows it when it reached 90+'c but it actually reached 95'c and stop there. The overclock speed at that point was 950/1219 mhz respectively.
The reason i am not pleased it's because i have a really sweet liquid cooling setup that should more that deal with getting rid of such temps and i know it's working fine so these temps were unacceptable. I have have a 3x140 rad and a 2x 140 rad seen in the pictures here. And these rads aren't thin either lol.

I decided to remove the entire block and get rid of the current thermal setup. I went and bought a sheet of pure aluminum ($5) (i couldn't find copper) so as to cut a small strip off it to put on both sets of vrms. Next I went and sanded the strip since the sheet had a weird groove thing on the surface and I wanted the surface completely smooth. Then I placed the double sided tape around the vrms to prevent any kind of unwanted contact with the aluminum strip, only the top of the vrms were left open. I then added some new thermal pad I had just bough that is really good at heat transfer. Let me look at the receipt for their names…..ok one is called phobia thermal pad and the other is fujipoly premium thermal pad with high heat transfer ability.
Anyway I added them to the memory and any other area that needed them as seen in the pictures.
I also added just a bit of non-conductive mx-4 thermal paste to the top of the vrms before placing the thermal pads on them. Then I added a little XIGMATEK thermal grease with gold grade thermal matrix on the top of the top of the thermal pads (I am not taking any chances). Next I placed the aluminum strips on the thermal pads. I then added enough XIGMATEK thermal grease on the top of the aluminum to make contact with the waterblock.
I then ran the same test and was shocked .

Apart from helping the cooling for the vrms, I also wanted to improve the gpu temps. I found that the back plate of the 5970 card runs very warm when you are overclocking. I decided to make a little gadget that would help in cooling my rams, North Bridge and also the 5970 back plate. My case would be cooler also as a result of this gadget. Here are some pictures of it.

Thanks lol amstech, yes they are. Anyway here are pictures of the temps with an even greater overclock, with higher room temps. And look at my gpu temps. They use to run at gpu 1 31.5'c and gpu 2 at 35.5'c. Now they are at 26'c and 33'c respectively. If you look at the pictures below you will see the temps before and after. Picture 1 test actually saw max vrm temps reaching 95'c but the second test saw a max reaching 75'c, a huge 20'c difference.

After a few hours of kombustor the vrms never budge in temps from the 75’c. Now after kombustor, I hit the gpu’s with Crysis benchmark. Believe me at maxed settings, this benchmarks will humble any card….or so I thought.
Take a look first at this huge overclock then look at Crysis. Room temps were at 77'f/25'c. The highest the vrms got in this benchmark at max settings was 65'c. I place the mouse over the monitor to idicate the highest temps as seen in the picture in Gpu-z. And look at the frames, yea i am a happy camper at this point.
