[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 1642

post #16411 of 38701
My 7950 is set to arrive today, look it up on the egg this morning and the blasted thing had dropped $20. Not that I expected them to do anything, but I opened a chat window with CS anyhow, and politely asked if there was anything I could do about the price drop, I do order quite a few things from them fairly often after all. (As most on OCN do I'm sure)

To my surprise she's sending me a $20 gift card to make up the difference, sure I have to spend it at the Egg, but it's a whole lot better then the nothing I deserved. I love NewEgg, and their customer service. Gestures like this are why I solely shop there, and recommend them as the only place to shop if you want a painless ordering process!

Not true. The GE BIOS raised my voltages, substantially so.

Stock BIOS, card #0: voltage under load 0.98V
GE BIOS, card #0: voltage under load 1.05V

Stock BIOS, card #1: voltage under load 1.05V
GE BIOS, card #1: voltage under load 1.11V

Besides, many reviewers got a nominal voltage of 1.218V-1.256V flashing their reference cards to the GE BIOS, up from 1.175V nominal. The boost voltage logic is in the BIOS, not in the hardware.

So I wonder if it would be worth it to flash my 7970's to the GE bios?

It's not going to make your card into a GE card ya know but how your card reacts to the voltage control will be interesting. Many people end up losing voltage. Check the GE bios thread.

It is a great tool for a simple OC setup. BIOS flash and CCC, no messing with 3rd party software for voltage control or removing clock limits. That's the way I like it.

Being that GE is a BIOS change and a different binning procedure, I'd say it pretty much does.

I ain't buying a single "GE BIOS lowered my voltage" post unless there's actual voltage readings.

Is there any good aftermarket cooler for 7950 ? I exclude the Accelero Extreme because of rubbish VRM cooling.
Anyone is using Alpenfohn Peter 79XX ?

I've not seen that cooler, but based on the design and specs, it probably looks like it would be very good for cooling a 7950/70. Only issue is the weight on the cooler would cause far more PCB flexing.

I would have to agree with that. Minor differences between the products.

First I'd like to express my extreme paranoia of anything code-named, or model named, Peter.

Otherwise it looks solid, I'm just curious how you go about sticking two 140mm fans to it. I guess they expect you to mod the existing shroud? Where's a picture of one of these in use?

Update: it wasn't my 7970 that suddenly got a defect in the DVI port... of all things it was my shmancy DL-DVI cord from Monoprice that went bad. The super thick kind. Thankfully I have a few, so I was able to replace it. All is well - false alarm!
