Hey guyz, i have ran into this problem......its not a problem just a glitch from the sapphire side,
I m using hd7950 vapor-x oc with boost, V4 series bios, the problem is the card doesnt overclock when using second bios (that provides boost)
the core is stuck up at the base clock of 850mhz even with the second bios.......!
Submitted the ticket at support....can u guyz help me out here....?

^^actually the second bios is a boost bios so...it has to work when load increases, without touching the LI ......!
Could it be the bios, thats not working properly?
and btw i checked the temps they are normal....i meant the core(58~65 on load),vrm 1& vrm 2 (89~65 collectively on load) when Li set to +10 (stable clock of 950mhz)
But it should be working as advertised (second bios).

The whole series is facing this similar problem,I believe you have got the latest Bios. The LI has to be touched otherwise it wont work,or wait for a new Bios.

Sapphire posted this on facebook couple of days ago:-

SAPPHIRE Technology has just announced an updated BIOS for the first release of its award winning HD 7950 Vapor-X edition (part number 299-2E210-201SA) which enhances performance by raising the AMD PowerTune specifications to allow higher and more stable clock speeds under load. It is recommended that all users of this product download this BIOS version and upgrade their card for optimum performance. Later releases of the card already have this feature implemented and require no upgrade.


And here's the link to the BIOS:-

If this is your card, better to update the BIOS.

Followed the procedure ....pp slides in the zip file, flashed and voila solved.....
Using gpu-z,hwinfo64 for temp verification......no need to run heavy benchmark to check the stablility
open gpu-z
cllick on the "?" near the bus interface (it is used to check the bus speed for pci-e)
click on "start render test"
You will get all the results,while running the test
ON full load:

core (950mhz) bios-2 ....temp 60~66c
vrm 1 temp.......77c(max)
vrm 2 temp.......74c(max)

nope......voltage locked...doesnt responds to voltage change...over volt or undervolt !!!!!
Does any one know how undervolt.....to bring down the temps(65~67c load)
Specially vapor-x 7950...!

AFAIK, B2 is locked so that you can't fiddle with it and if the first one develops some snag, you still have a working card. Dual BIOS on mobos works similarly.
