Which program did you use to adjust voltage? I have heard nothing but horror stories regarding the voltage lock.
Hey Leh, glad you got on the good side of the Vapor-X finally! It is great, isn't it? A pity you cannot go higher in OC, but above 1100 MHz must be considered good. The performance scales really well with the core clock, but the overclocking the memory does not much more than increase the temperature in my case. I have 950/1250/0.95 (stock) giving 54 C maximum but 1175/1250/0.95 still stays under 60 C and I get ~+20% more FPS.Just wanted to update this.
I originally had bought a 7950 Vapor-x 6+8pin which was unstable with hot VRM's. Sent it for RMA... and more than a month later, I receive a 7950 Vapor-x 8+8. Turns out this card is amazing.
Compared to the regular boost card, it runs cooler, quieter, overclocks better and it's voltage unlocked. Currently running at 1120 / 1450 @ 1.22V - the regular card clocked to 1100 / 1250 @ 1.25V. Temperatures are only 65C for both GPU and VRM, about 10C lower! I've only done limited testing in Heaven and Witcher 2 so these clocks and volts are still subject to minor changes.
I've tried clocking it higher but can't get 1150 stable even with 1.32V. Not worth it.

Set to 0.95 V in Trixx. The reading in RivaTuner (MSI AB to be precise) is higher than that, but I heard that it is not calculating the voltage correctly. Also someone on this forum (lava?) measured it with a voltmeter and found Trixx setting to give the almost the correct value. Since 1175 MHz is fast enough for me, I have no wish to increase the voltage, but I checked and AB cannot change the voltage, while Trixx can.What voltage is your card at 1175?
0.95V? My stock voltage is 1.15V . Yours just can't be right, I'm going to assume that 0.95V is the idle voltage... have you actually tried adjusting it, and does it result in a different VDDC reading in GPU-Z? I'm of the impression that the reading in GPU-Z and HWinfo64 is the real voltage after Vdroop, so it should be lower than the nominal voltage set in your overclocking program
IMHO, from what clocks people are reporting here my conclusion is that ASIC does not seem to be the most important thing. If it works fine, it is fine.ASIC is only 56.2 on my Dual X. I'm wondering if I should get a new one. But that would be lottery all over again.

Uhmm, that looks really bad. I do not have that bad performance ever, and those white flashes should not be there. Are you by any chance alt-tabbing out and back into Heaven? You have some crazy stuttering that I only get if I alt-tab like I just said. Also check that you have no other process taking up CPU or HDD resources.Ok, so I ran Heaven benchmark at stock clocks a few times now and notice that the screen flashes white from time to time. Could those be artifacts? I'll try posting a youtube upload here in a bit.
EDIT: Ok here's the video. Are those artifacts? It shouldn't be artifacting at stock clocks unless I have a faulty card. There was another anomaly in one of the previous benches I ran (at stock clocks) that was far more severe, like black and white triangle shaped anomalies that appeared only that one time and lasted for a split second. I wasn't able to reproduce those on the run through I recorded though.
What's weird though is that I haven't seen this in any of the games I've played since installing the card. When overclocked to 1050, I did notice the screen briefly freezing up for a split second here and there when playing a game.
No alt-tabbing. At one point I was uploading a video, it does appear that I had more of those flashes while uploading. But even when not having anything running in the background I had those flashes. What's weird though is that this happens only in Heaven, not any of the games I've been playing (Future Soldier, Metro 2033, Total War Shogun 2). What I did notice in the games is that the screen will briefly freeze/ lag from time to time. I thought it was the drivers though.
