I've always gone with the order found in GPUZ. Currently 5 for 5 smile.gif

How critical is it to flash a bios from your vender?
I'm using the Gigabyte windforce R9 270, which has a locked bios. I can't change the voltage at all, which is a shame.

The card does 1175/1550 on stock voltage and hits 60C under load. I'd like to go higher, as it is water cooled and I've got some fans on the way to keep the temps in check. Would it brick my card to turn it into an XFX 270X or something? Thank you in advance. For reference, this is the card I have: http://www.techpowerup.com/vgabios/150214/gigabyte-r9270-2048-131028.html

I've tried MSI afterburner with all the cfg tweaks to unlock it, Gigabyte OC guru, RadeonPro and good ol' CCC to try and get more than 1.207V into the GPU, no dice.

Different vendors use different settings within their vBIOS. Personally I wouldn't do it. Tried it before with a Sapphire HD6850 (tried a MSI BIOS) and while it did not brick the card, I sarted to experience hard system freezes even at stock speeds.

By the way, you say your BIOS is voltage locked? I was planning on getting a GB R9 270X, but if their vBIOS are locked then I may reconsider.

Edit: Have you tried VBE7 yet? It's for editing the vBIOS on HD7xxx cards, but the R9 270s may work too. Some people are able to modify voltages in their vBIOS even when they are software locked.

Yea, I believe the 270's are voltage locked. I'm not sure what to do with VBE7. It sees the BIOS (one of my backup images) and populates the fields. What should I modify to bring more power to the card?

EDIT: This is what I see. The highest clock, and the VDDC that corresponds to the fastest 100% load setting is labelled as "boot". I don't want to change a setting and then brick my GPU, and be unable to get into windows to fix it

The changes you want to make are under the PowerPlay tab. Find the "Performance" state and change clocks corresponding to you "3D" frequencies (or leave them alone for now). The value below the clocks is the core voltage. Change that. Save the BIOS and flash the card (make sure you have the original BIOS backed up on a USB key and have a spare card in case you brick your card). If all goes well, do a fresh install of the drivers and see if the new voltage value shows up.
Again, I don't know if it works for R7 270 cards.

Note: Use ATIFlash to backup your original BIOS and to flash the card, don't do it from Windows.

Worked like a charm.

I downloaded a bios from techpowerup which is the one for my card. I then backed up my default bios and started messing with the BIOS that was downloaded from techpower up.

I changed the VDDC from 1.21V to 1.31V.
I then flashed using ATi flash and rebooted. The Gigabyte tools still saw only 1.21V, but GPUz and MSI kromebuster (however it's spelled) both saw the voltage bump.

With a full 0.1V, I couldn't get the elusive 1.2Ghz. I tried unigine valley, and it locked up at 14 runs. (Which sucks, 0.1V should be enough for just a 25Mhz bump right?)

Anyhow, I made it through the benchmark at these settings:


It scored 1284 points on the ExtremeHD setting. Which isn't bad, I think I can do more tweaking. Temps haven't moved, it went from 61C to 62, occasionally 63C at most.

There must be something up, because a 0.1V increase on my CPU yields more like 10 more degrees, not 1

EDIT: I would love it if my $199 card could roughly equal the $299 GTX 760, that's my end game here

You can't compare a CPU core to a GPU core like that, temp wise at least.
I would do modifications on your original bios and not download it from tpu (unless you lost your bios and don't have another choice). Just keep one unaltered copy somewhere safe and a second copy to edit.
Try bumping the vcore a bit more.

Just remember to always do a clean driver install every time you flash. Sometimes the driver sees the "ghost" of the old bios and will not reflect changes.

Edit: A lot of GB boards tend to be **** for overclocking, so maybe you hit a wall.

what about the risks involved with flashing bios? what is the worst thing that can happen? can you revive the gpu if the worst happens?

You kill your card.

If you have a spare GPU, and at least 2 pcie slots, you might be able to put another card in there as your primary, then reflash the stock bios back onto your dead card. That should revive it, assuming you didn't blow the card (if you were overclocking)

what if the gpu has a bios switch? can that save the card?
