From what I can tell, it seems like the 7970 and 7950 non reference by sapphire are VERY similar. I mean other than aesthetics, do you think there's any real problem with cutting around "boost" button and capacitors?


I would rate this mod a 8 out of 10 on difficulty and its not cheap to do. I spent alot of time planning it out and getting the parts to do it.

I did all the cutting with a dremel and did some drilling for the heat sink mount.

If you don't do this just right I could see this mod going terribly wrong so if you plan on doing it, it is possible but I wouldn't recommend it to somebody who isn't good with their hands and tools.


I agree that the stock fan is loud and not very effective for cooling compared to my custom water block.

Thanks for the response. I'm pretty good with my hands if I take my time. (trust me, finding parts to fit old '71 MGB GT can be a meg PAIN! so I use almost fitting parts and modify)

I hope you don't mind me asking, but how much did you have to drill for the heat sink mount, and was that the only "board" side carving you had to do? I might still do the project, only cause I have alot of stress that grad school has put on me...so I need a tough project to relieve it =D.

I cut off a small area of the stock heat sink plate that goes over VRM1 (memory) and put some stick on aluminum heat sinks on it with the fujipoly xtreme ultra thermal pad below.


The VRM #2 (main power) heat sink was used from the XSPC new edition aluminum heat sink. I cut it with dremel. Drilled 2 small holes for the copper VRM block on top of it.


I used a small round file to clean up burs.



It's really not that tough if you feel confident about your ability to work with your hands and the tools.

Not trying to scare people off from doing this but I also wouldn't want to see people blow money on the parts and ruin the mod. Good luck if you do it.

Still haven't figured out how to over clock the card.

Here are some temps from a full screen run 1080 of furmark.

Ambient temps is 24c.

I own a variable speed dremel with fresh tips and I have a good and steady hand, is there a way to go about this and only waste money on the cooling block rather than risking both block and card.

Maybe you could explain your process in some grander detail so those of us with the will can more easily find the way.

I only bought the XSPC RAZER NEW Edition HD7950 block for with this mod in mind and it worked so it wasn't a waste of money to buy it. I have shown enough photos to share the basic idea of the mod and I feel that if one were to do this mod the photos I have shown are enough to get the idea and do the mod.

If you need more detailed instructions I don't think this mod is for you + I don't want to be responsible for this mod going wrong. It's a great mod and if you do it good luck and post your results. smile.gif

With these ultra low core and vrm temps,

you should try Modded Sapphire Trixx 4.4.0b that allows 1.38v on the core and 1.7v on the memory thumb.gif

The file is floating around in a thread here on OCN

I have tried it along with custom edited BIOS and nothing works to get this card faster. My card run nice and cool under the most intense loads at 1275/1500 but the card will not go faster than that.

I think the BIOS has some type of current protection either programmed into the BIOS or a physical switch that shuts the card down when a set current is reached. I wish the card was faster. The VRM is immense and looks like it has alot more to give.

I agree with Sonda5, one of my card has same elpida memory as Sonda... max memory is also 1500... 1505, it will just crash...... although I cant reach 1275 as him cause i have stock cooler only.... and this stupid elpida card is holding back my hynix card.... its like pulling it down...
