acpowell Posted August 26, 2013 Posted August 26, 2013 (edited) I recently purchased a MSI HD7950OC TF3 PCi3 from microcenter. It seems like a great card. I was looking up some things about it for overclocking and I seem to stumbled across something odd. Every single 7950 card I find MSI or otherwise seems to have 6x6 power plugs. Mine has a 6x8. When looking on MSI's site they don't show photos of that side of the card. The card even came with a 6 to 8 pin adapter. Anyone else have this card and know why it seems to differ from all the other 7950s or did I get some other magical thing? This was not an open box or anything that I am aware of. **UPDATE** Found a post on another site that said this: MSI has started using reference 7970 PCBs for their 7950 Twin Frozr 3 OC cards Here is the link to that site although it really was created to talk about Aquacomputer 7950 blocks: http://hardforum.com/showthread.php?t=1704168 Edited August 28, 2013 by acpowell Share this post Link to post Share on other sites More sharing options...
acpowell Posted August 27, 2013 Posted August 27, 2013 well as it turns out the box says I have the BE version although there is still nothing that says it uses a 6 and an 8 pin for power. Share this post Link to post Share on other sites More sharing options...
acpowell Posted August 27, 2013 Posted August 27, 2013 The more I read into this the more confused I get. I bought this at microcenter and when I look at my online receipt it shows I purchased this: http://www.microcenter.com/product/403013/R7950_TF_3GD5-OC_AMD_Radeon_HD_7950_Twin_Frozr_III_Overclocked_3072MB_GDDR5_PCIe_30_x16_Video_Card#tab-specs But the Specs listed don't match up to what GPU-Z reports which is this: http://gpuz.techpowerup.com/13/08/27/980.png I have not overclocked it or anything, but I had wanted to see if I could get it to 1Ghz which from the looks shouldn't be too hard. Anyone know what I am looking at here? Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted August 27, 2013 Posted August 27, 2013 I believe that means it has a 7970 pcb, should overclock VERY well... I'd even consider trying to flash it to a 7970 but atleast OC'n it high! Share this post Link to post Share on other sites More sharing options...

I'd even consider trying to flash it to a 7970 but atleast OC'n it high! considering it is only a few days old I don't want to go flashing things to other things just yet, but I was going to try overclocking it this weekend. I am only playing FFXIV ARR so it is not like I am playing Crysis or something. I was going to use the MSI utility to over clock and I suppose you just increase a bit then run the benchmark for a while and see what happens eh?

IVIYTH0S Posted August 27, 2013 Posted August 27, 2013 Yeah do that... maybe look into the flashing though...could be a diamond in the rough Share this post Link to post Share on other sites More sharing options...
acpowell Posted August 28, 2013 Posted August 28, 2013 Yeah do that... maybe look into the flashing though...could be a diamond in the rough Well I just maxed out the core clook to 1100 on afterburner and I have zero issues. When I change memory MHz it doesn't see to do anything so I am not sure what that does for me. and I don't really know what else to change.

Waco Posted August 28, 2013 Posted August 28, 2013 Sounds like you got an older model before they started using different PCBs. Good find! Share this post Link to post Share on other sites More sharing options...
acpowell Posted August 28, 2013 Posted August 28, 2013 So I have literally maxed the core clock to 1100, is there anyway to force it past there? I have not touch the memory clock yet though, so I don't know if I should or shouldn't. Waco: I don't know about older or newer but I agree about the good find. I have never had something that when I put it to the max, it just worked flawlessly and didn't even over heat much. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted August 28, 2013 Posted August 28, 2013 You tested it in a couple games?? Share this post Link to post Share on other sites More sharing options...

The only game I had installed I couldn't get online because of congestion, but I had kombustor running at full tilt for a while. I am going to try and get on to FFXIV ARR tonight and see how it goes since that is the game I bought this card for anyway. Also I still am not sure if I should try and increase the memory clock, or how I know when it is too much. Also I really would like to know if it is possible to go past 1100 which is what the slider maxed out at.

IVIYTH0S Posted August 28, 2013 Posted August 28, 2013 Try a wide variety of games, if you want the best stress test. "Stress tester" programs often let a lot slip by and a variety games will test all different aspects of the card...For instance Crysis 1 let alot of my instability slip by but C&C 3 failed, so even the most trivial game could reveal the fact that you need to turn down the OC a bit Share this post Link to post Share on other sites More sharing options...
