January 17, 201312 yr Hehe ... no worries. I've played with that board more than once, glad to share workarounds
January 18, 201312 yr I'm out. Matrix 7970 is dead after 2 minutes under LN2 on stock settings... No second card
January 18, 201312 yr ouch, that sucks ..... I had no luck with those 7970 cards. I tested about 20+ till now and found a decent one on air just some days ago lol. on ln2 we tested about 5-6 cards, no one could do 1500+ .. 2 lightnings neither

I only have the 1 that I tested. 1315 air heaven, no mods (1900+ memory possible)  mabye im just lucky (alot)  7970 is a visiontek ghz edititon (has all phases, not missing 1 like ref) i use this for gaming. far cry 3 is really fun atm. cpu is good (6.8+, best of 5 samples tested, all retail bought from Frys) mem is good (2600 c8 air for psc and bbse almost every kit i have can do this) imc is 2800 32m capable  lucky luck is lucky? none of my stuff is hand pick. all retail ordered so i didnt choose samples.  i think some of chew*'s "always work" philosophy has rubbed off on me Edited January 18, 201312 yr by zeneffect

Frequencies in 3D11 Â Â 12 Lightnings 7970: Â 1. died stock 2. 1625/1825 3. 1660/1800 4. 1670/1900 5. 1760/2020 my golden one which gave me ticket to MOA Finals 6. 1650/1950 7. 1500/1800 8. 1550/1900 9. 1500/2000 10. 1600/1850 11. 1550/1900 12. 1500/1870 Â Ref cards: Â 1. 1500/1850 2. 1550/1800 3. 1570/1900 4. 1550/1870 5. 1350/1750 (GHz Edition, Vapor-X Sapphire, ref design but all phases)) Â Matrix: Â 1. 1610/1980 2. 1625/1800 3. 1600/1850
January 18, 201312 yr wow 20+ cards is alot. I only have the 1 that I tested. 1315 air heaven, no mods (1900+ memory possible) mabye im just lucky (alot)  7970 is a visiontek ghz edititon (has all phases, not missing 1 like ref) i use this for gaming. far cry 3 is really fun atm. cpu is good (6.8+, best of 5 samples tested, all retail bought from Frys) mem is good (2600 c8 air for psc and bbse almost every kit i have can do this) imc is 2800 32m capable  lucky luck is lucky? none of my stuff is hand pick. all retail ordered so i didnt choose samples.  i think some of chew*'s "always work" philosophy has rubbed off on me  only 5-6 of them was under ln2 but all sucked. because of that little shim over the gpu or just bad contact or just they were bad clockers.  now i have a rented cpu from INTEL which is my best one ( 6.7 valid ) and bought a good PSC kit ( 2600 c8 32m ) and now this card seems good with 1300/ 1850+ heaven im maxin her out right now
January 18, 201312 yr only 5-6 of them was under ln2 but all sucked. because of that little shim over the gpu or just bad contact or just they were bad clockers. now i have a rented cpu from INTEL which is my best one ( 6.7 valid ) and bought a good PSC kit ( 2600 c8 32m ) and now this card seems good with 1300/ 1850+ heaven im maxin her out right now  watch the core clocks at the limit. I noticed mine wanted to jump up and down a bit hurting score.
January 18, 201312 yr watch the core clocks at the limit. I noticed mine wanted to jump up and down a bit hurting score. Â 1300/1850 is the max of this. 1310/1850 passes but lower score, or freeze just at the end now onto the 2k11 just for fun. that bench is absolutely RAM mhz limited ...
January 20, 201312 yr Hi i have question... Why i dont participiate second stage with i7-3770K on 2 cores ????
January 20, 201312 yr only 5-6 of them was under ln2 but all sucked. because of that little shim over the gpu or just bad contact or just they were bad clockers. Â If you want to run 7970 on LN2, you have to remove the shim
January 20, 201312 yr Oh man..after finally yesterday I found an i5-661, GB h55n-usb3 , and a working 7970 Lightning to use, my lab and it's surrounding have electrical blackout for about 48 Hrs now due to the flood... Â Better luck next time I guess ()
January 20, 201312 yr saya pake h55n-usb3 mini itx with i5 650.. only get 4,8 ghz stabil with corsair h80... , with msi 7970 xfx and msi 7970 lightning..
January 20, 201312 yr Great to hear that, my card sucks another did not came in time so that's it from me...
January 20, 201312 yr If you want to run 7970 on LN2, you have to remove the shim  not as easy when you have to keep warranty
January 20, 201312 yr Use copper plate - 0.5mm thick, I did with it 1750+ on my golden lightning  tried that too. the problem was with the cores actually as they sucked anyway with the copper plate you have to be really careful to have a good mount you have a badass card. i would give my half arm for a 1600mhz benchable one --
