I think 3dmark11 is the tougher one for testing the core, it makes a pretty heavy power draw.


Hmm...so would you say that the cards aren't getting enough power? Approximately how much should they be drawing at 1300 core/1.21 volts and power limit at 109%? Are there any other good benches I should try to see if the issue can be isolate further?

More voltage for the clock should let it pass the 3dmark tests, not sure about the power draw at that clock & voltage, I was mainly watching the kill-a-watt at 1.45v +.

If looking for a 24/7 game stable overclock the 3dmarks & heaven/valley are good starting points, when they all run smoothly then playing the games & fine tuning if needed (starts artifacting, bit more voltage or less OC) should get it all set.

Yeah mine just stays green, regardless of what I put it through.

Well, I just finished running a flashed bios vs reference on valley. My flashed bios scored exactly the same as my reference bios that was max clocked. My reference bios was boosting solidly to 1375, and my flashed bios was stuck at 1375 on its run. Both were run with the memory at + 800. The score is the exact same for both. As I said earlier, the regular bios must be boosting a bit past what you are doing on the ln2 bios. On another interesting note, my stock bios once hit 116% power target. The highest my flashed bios has ever hit was around 110 or so. That was with the core at 1450. ???

I would suggest games as Ftw 420 has suggested. I did not discover that I needed more than +100 on the core until I tried some games. Metro 2033 showed me that I needed a bit more core to get things stabilized. I'm still working out the final kinks, but it is looking like it needs to be about +125 core for me to stay stable at 1400 core. Crysis 3 will be my next true test of memory overclock as it is just brutal on memory. Good luck. thumb.gif

With a bios using a modded power limit they can look different, the one on my card I leave it at 100% & see about 50% power target at 1450 core.

I have to be honest, i had no intention on joining this club. I was browsing for a 2nd 7970 to xfire with my TF3 on my local microcenter website, when i realized that they had a 780 lightning (open box) for about 60$ LESS than the D.D. 7970. So guess who said "its time to switch teams", and whipped out the credit card? ME! I think I will end up putting the stock cooler back on the 7970 and let it find a new home. I will formally join sometime in the next few days, but i wanted to go ahead and say HI, so i would be subscribed. I am going to do some back reading in this thread as well to get a feel as to overclocking potential/demands on air and water.

Since everyone in the classified club seems to be an arse, I went ahead and got this toy instead of a classy..
Hoping you MSI guys have a bit more level heads smile.gifthumb.gif

Okay so i currently have the money to do either of the followig 1- water cool my whole system (cpu - 2 msi lightnings ek)
2- or upgrade from i7 3820 to i7 4930k and h110i cooler for the cpu. Which option would give me more performance in gaming !! Thanks in advance
