After one hour of BF3 at 1920x1080 Ultra (without AA and Blur)
With 1100/1575 and AUTO fan speed , values from GPU-Z looks quite good:
max fan speed 53%
max gpu temp 60 oC
max vrm1 temp 92 oC

The Sapphire Vapor-x is not voltage locked when you select the normal 850 mhz clock.

Thanks now what is this I hear about coil whine? Only amd gpus I have owned didn't have it (6950,6970,7950). Is it annoying?

Not true, mine locked on both bioses... (sapphire trixx and afterburner checked - still 1.006v in GPU-Z sensors)

BIOS ver: 015.025.000.001.000000 (113-210P2HY-V03)

There isn't coil mine on mine, only when its running at a very high FPS as in 2000 then it would whine. It's not that annoying if you do have it and you can always RMA your card. I've had a PSU that had coil whine but it wasn't that loud or annoying. I guess it all comes down to the VRM and capacitors.

Which version of Sapphire Trixx are you using? If your not on Sapphire Trixx please go here and download the latest version (4.3) https://www.sapphireselectclub.com/ssc/TriXX/TriXX.aspx

Just try downloading the latest version of Trixx if you haven't and use that to overvolt. I'd recommend against using Afterburner due to stability issues.

If all that doesn't work then try flashing your Vapor X with a 950 mhz bios. The link is here http://www.overclock.net/t/1281711/hd7950-revised-with-reference-hd7970-pcb-club#post_17724563

or

Sapphire Trixx (4.40b)

I have this BIOS from 7950 950mhz(black 7970pcb), because that was my first card, and was RMA.
Using trixx 4.3, so should try with 4.4b now.

1. Using a 7970 bios would only provide you with higher clocks and a higher stock voltage. You shouldn't need to use the 7970 bios as those speeds could easily be achieved by some overclocking. You have to be really unlucky to not get 925 on core clock.
2. That early version of the 7950 is a reference design non AIB 7950 board.
3. The Vapor X is only voltage locked when you select the second boost clock. It's completely voltage adjustable when you select the normal 850mhz bios. Check out this review for the cooler and temps - http://www.techpowerup.com/reviews/Sapphire/HD_7950_Vapor-X/
4. VRM vary from manufacturer to manufacturer, but its best off to keep the temperatures below 90. The 950 mhz ed. uses a reference 7970 design, the difference being an added VRM.
5. Yes, however you would void your manufacturer warranty. Just remember to use a thin layer of thermal paste, rather than the slop that Sapphire slapped on. I STRONGLY recommend you improve your VRM cooling if you are going to overclock your card. The VRM temperatures was what stopped me from going to a higher stable core clock.
6. Yes, yes and yes. But as long as your very careful and don't damage your card in the process you should be fine.
7. Yes, but I never knew sapphire would publish a new revision of a BIOS. Mind linking me?
8. I cannot say your temperatures, but I'll give you mine as a reference. Mine is currently overclocked at 1235 core clock, memory 1250, voltage 1.162, custom fan profile. The temperature is 32 idle and 68 load. However in mine the VRM cooling is bad and adding any more voltage would cause my VRMs to heat up to 110.

Thanks alot! rep + btw this is the PIN N: 11196-10-40G but some say the EU version is 900 mhz clocked, with same PN from USA with is 950, TBH i don't care for 50mhz as long this card is using 7970 PCB and the improved PCB aluminium pads, the versions with blue PCB look quite a bit inferior in that regard, also the VRM design look cheaper as well.

Btw how come on "yours" the VRM cooling is bad? the Sapphire 7950 950 core, should be the best build 7950's out there or i'm wrong? i will be getting this card in 1 hour.

My first card was 11196-10-40G EU version, and that was 950mhz ver with BLACK pcb,
http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1551&psn=&lid=1&leg=0

many of users with blue pcb thinking at they have this 7970 reference board, but thats not true. Just look at power connectors - black 950mhz with 7970 PCB have 8+6pin, and that other have only 2x6pin

Have you tried Trixx 4.4.0 beta as thats 1st version which supports properly voltage control on vapor-x. With MSI Afterburned you need to select "constant voltage" from the setting to voltage control to work (proper support for amd cards with boost are likely coming later).
