Quick question: Is the set of "dual bios" with my Sapphire 7950 card the same?

post #1 of 6
Thread Starter 
I guess I could check, but I never got around to it so I thought I'd just ask: is bios #1 the same bios as bios #2 on my Sapphire 7950 card?

Initial impression of this cheap Sapphire 7950 (810 core/1250 mem) was bad. The backplate of the card looked flimsy and badly fitted onto the rest of the card, where the outer part was skewed 1mm outwads compared to the inner part of the backplate.

A lot of soldering on the back of the card seem to be omitted. There are 5-6 areas on the back that probably should have been soldered, and one of the parts are only soldered half way over. A larger part on the other side of the card is also not soldered. Images of similar cards on the internet show these parts to have soldering.

Example off the internet showing soldering on these places on what probably is a 7950 card:

The card I got seem to overclock ok. Currently running it at 1100 MHz core and 1500 MHz memory. 1200 MHz core seem ok, just have to up the volt abit more probably. VRM's seem to lie at 82 degree C when running with 1200 MHz core and 1.200 V. My case ventilation is not the best (is currently set up for running quiet with fewer fans).

Btw, if anyone know how to autorun Saphire's Trixx software on a standard account in Windows 7 while avoiding the UAC promt on startup, I would appreciate to learn about it. Otherwise I might be tempted to turn off UAC.

This thread is a month old but just in case the OP still hasn't gotten an answer, the 2nd BIOS is aggressively set (OC'd more) compared to BIOS 1.

As for some parts missing solders, I have the exact same card (Sapphire HD7950 OC edition) and all the parts in the picture above are soldered.

I guess the important thing is the card runs fine!

I made a so called 'ticket' at Sapphire's website and they replied, making an attemt to explain why there was no soldering, but they ultimately made no sense and I had to guess at what they meant.

From what they wrote, they tried to make some kind of point of how the card was from an older batch and that they made some kind of change to the look of the pcb for making it look cleaner or something. I guess adding soldering on later batches made the card look more presentable.

And finally, they finally did managed to make themselves understood by pointing out that there was nothing wrong with the quality of the card.

A manufacturer is always going to say theres nothing wrong with the card if they get support tickets like yours. Ultimately their reasoning based on what you have said does make sense. Its not essential for all parts of a card to have soldering on, but for presentation reasons manufacturers usually cover these areas with solder although it doesn't really make any difference either way. I would perhaps be a little concerned about the component you describe not being soldered properly. If you have the skills, I would consider resoldering that component to ensure reliability. As for the dual BIOS, I'm yet to come across a card where the 2 vBIOSes are different, one is simply a backup for if you fudge a vBIOS flash.

Just want to clarify that there are just tiny holes in the metal visible on smaller areas of the pcb, so there doesn't appear to be items lodged into that kind of surface. I too was wondering if components would fall off though, but it doesn't appear that it would happen here because I can't see anything sticking out from the pcb.

Actually the dual bios does have a different clock setting and the fans ramp up more aggressively in the 2nd bios as well, so there is a difference.

A quote from legit reviews; "...On the OC edition that we are reviewing here today, the second BIOS is pre-programmed to allow a higher maximum overclock and more aggressive fan profile."
