Its good but the undervolt is not enough, I prefer 0.963v or 1 volt....

For you perhaps but for me it is enough, dropping to a lower voltage on my rig decreases stability and I lose more coins from downtime than I do from achieving the extra 1.5 watt drop at the wall that I could get at 0.963v.

I am not in competition with you to get a lower voltage I am in competition with my rig to get more hash per watt.  Grin

It depends on how much you are planing to overclock, you can flash your voltage to be the lowest possible...

I don't think vendor's bios is undervolted right?

Stock vendors F43 BIOS runs at a lower voltage than the later BIOS, undervolted and run cooler.




Do you know how much they undervolted? I found some online bios which is 0.963v..

They are floating voltage but run at around 1.05v when running scrypt at I19 delivering a steady 640Kh/s, note the VRM temps.

You can still undervolt it with afterburner right? Cause most people usually don't wanna flash their GPU unless they are having like 100 of them... flashing GPU will void the warranty...

Some 7950's you can and some you cannot. Flashing the BIOS with the vendors own BIOS does not void the warranty as they supply both the BIOS and the tools to do it with, check out the vendors download sites.

With a  dual BIOS like the 7950 if a mistake is made in flashing it then you can flip to the working BIOS and then flash it back to the original.

Some cards have switch and 2 BIOS chips. There is no way that you can damage your card because you can always switch to 2nd BIOS if something goes wrong with the 1st one. Wink

Yes, it can be flashed. But why you wanna flash it when you only have few GPU?

Heat, the F43 BIOS runs a lot cooler when mining especially the VRM's which have a tendency to blow if they get too hot. Running cooler also means that less Watts are used to produce the same amount of shares.

Yes this card can be flashed but are you sure you wanna buy some overpriced 7950? you can even get yourself a 7970 with $200...

The price for the 7950 is very reasonable.. $185 for a card with a year warranty left on it...

plus the power usage is considerably higher with the 7970 I was told.. can someone verify this?

Where can I find a 7970 for $200?

You have to look in around, sometimes there are a few cheap 7970 but usually gone pretty fast...

Is there a big difference between the 7850/7950/7970 (i've read the charts, I'm looking for REAL experiences here)

Most of the guides online say to use the 7850..

7850 is good for gaming, but not for mining. It is very hard to achieve 400kh/s with 7850, and with 7950 you can get about 600-630kh/s., and 7970 can get you 700+ kh/s.

So, considering [card price/ khs] ratio I would say that ATI HD7950 is the best bang for the buck. Wink

Got my R9 280X for 300$, if you wreck a BIOS on those 7950 you have a chance of breaking the card, and I would not recommend to do that.

I have an opportunity to buy this card for $200 (canadian).. it's a year old and has a year of warranty left. Should I ONLY buy this card if it can be flashed? What's the communities take on this?

I've heard some models cannot be flashed.. has anyone had experience with this card in particular?

Thanks in advance

Whay do you need to flash it? It has BIOS 1 with unlocked voltages and BIOS 2 with locked voltage and "Boost clocks". Just use the small switch to change BIOS1/BIOS2 settings.

Why not buy Sapphire 7950 dual-x instead? You can undervolt it easily without flashing the GPU...
