Also PROBN4LYFE what bios are you using currently?

I figured out that once the card is clocked even 1mhz above the default 1250 memory it will pump the full 1.240v to the core at all times. I can set the core to whatever I want and it will properly idle, but the ram is what messes it up. Right now I have afterburner set to a 2d and 3d profile so when I am not in a game the stock clocks are on and the voltage idles how it should and when I get into a game it pumps it up.

Oh well. Thought I could dodge afterburner with this update, but it seems not.

Exostenza, I just flashed to the F21 bios, the 2nd latest one.

I will tell you the reasons why it is better:

lower stock/load volts
means better cooling,
better temperatures,
more to work with,
and your 7950 will last much longer

The vddc is at 1.09v at load, 0.8-0.9 idle. This is SUPER GOOD. Although the clocks are 900/1250, you can clock them nicely with Afterburner to 1100/1500 or more if you want (if you tweak the cfg and add the ati.dll files so you can pass the limits) + you can set your own volts.

This is SUPER good, because right now I have a max volt of 1.162v @ 1120/1500 compared to the crazy too much 1.24v with the F3 bios in full load. If I wanted to I could clock them to 1200/1575 and set a max volt of 1.2v if my GPU has the juice for it to run it at 1.2v, that is 0.04V LESS than F3, and it means it isn't fluctuating so it is very good. Also, TEMPERATURES ARE MUCH LOWER. Up to 8 degrees lower. You have to get this, the F3 bios is bad. That high VDDC is unnecessary by far + it made my 7950 WF3 produce this ****ed up electrical sound. Now it's not there anymore, everything is very stable.

So I suggest that everyone here who has F3, deflash it to F21, set your own max NORMAL low volts, have better temperatures, more stability and a peace of mind that your 7950 isn't pushed to it's very limits by its overly high 1.24v vddc.

I'm pretty darn stoked to get my hands on the final version of this driver. For now I am using the 12.10 stable, but am very much looking forward to the 12.11 or 12.12 stable (when ever they get released as AMD seems to be taking their dang time releasing drivers lately).

Nice results! If you ever feel like pushing your cards even more you should watercool them! My max load is in the mid 40C with VRMs not even touching 50C, that's at over 1.3V as well. thumb.gif

The way I see it is my card has better than stock card temps at its current clock speeds which are pretty much on par with yours and it is not very loud at all - no way I can hear it over my games. This leads me to understand that water cooling is by and large a huge waste of money for a gamer as you need to buy a block, a rad and tubes to get something going that gives you little to no benefit over my air cooling solution and costs hundreds of dollars extra. Honestly. I would just get a second 7950 and double my performance before I got a water setup.

I get that this is an enthusiast forum and you want to push your pc and have awesome parts, but from my standpoint water cooling makes no sense as I like to make amazing rigs that are also amazing in the price to performance department.

I solved this by simply flashing a 950MHz Sapphire vBIOS to my TwinFrozr tongue.gif The Sapphire vBIOS actually works better than the MSI vBIOS, I can do 1100MHz @ 1.1v instead of 1050MHz, and GPU / VRM temps are quite a bit lower even though the Sapphire vBIOS feeds the GPU more volts by default.

That's very understandable. I was once in your shoes and thought watercooling was a big and expensive step (it really is). I made my loop over a long span of time, so it wasn't as "expensive" as people make it out to be. It's definitely not for price/performance, but rather silence/performance. The nice thing is you get to keep most of the watercooling parts over new builds aside from GPU blocks.

Hello great community of overclocker,

I am getting the Gigabyte 7950 windforce this week. smile.gif
So, do I have to update the bios on the card with the new one?

From what I understand I can overclock it and get the same result, is that right.
I am just asking this, so I don't have to go over the hassle of changing it.
( note, it is my first GPU).

Thank in advance.
