7950 boost button switch doesnt work? HIS 7950

post #1 of 9
Thread Starter 
Hey fellas, I have a HIS 7950 iceqx2 and I am wondering about my boost switch. I found where it is and have switched it back and forth(reboot after switch) and I cannot find a difference.

No matter what, I default to 950x1250.

What I find curious is the adverstising on the box 850 core clock with a 925 boost clock, both of which are not evident. Just curious if anyone else has experienced this. I am planning to call on Monday, but until then, I want to see if anyone else experienced this.

And what about full load clocks?

The card in idle uses several "power saving" features that affects the clocks.

It idles at 300core 150memory. When I first got it, it was in position two, under load I defaulted to 950x1250. I then tried twice 1, rebooted, and under load I had the same clocks.

Bump.
post #5 of 9
I had a quick look at HIS site-
Possible when using iTurbo (like MSI AB) second switch position allows higher voltage?
May not notice it w/o attempting to adjust...
Also,most cards ship from Mfg in position 1-
If your card was used, flashed to a diff BIOS for BOTH positions
you could have your hands full!
Enjoy!

Mine was in position 1 when I got it. Both default to the same speeds, bought it new from newegg. I guess I could try switching back and forth and see if the bios tag changes in gpuz?

Figured I would update this so if anyone comes across this thread, they have an answer.

According to HIS support, the 7950 iceqX2 comes with duplicate bio's. They are the same.

So, that explains why the same clocks. What I assume is that the BIOS #2 unlocks the voltages and the card can Boost higher clocks... HIS didn't said anything about that? I mean, as you put it, it seams a backup BIOS rather than a Boost one...

I already closed the case, but I could make a new one since they seem to respond pretty quick and get a clarification on the question.

Yeah, all they said were that the bio's were the same so if one went bad I had a backup. Its weird because according to their website http://www.hisdigital.com/us/product2-731.shtml it shows, "Core Clock 850 (Boost Clock 950) MHz".

I will experiment tonight after work and see of gpuz shows duplicate information for the bios.

EDIT: Okay, so I switched the switch to the other bios and accoding to gpuz, the bios version is the same. Hitting defaults puts them at the same settings. Both can overclock the same, both are voltage unlocked.
