Okay so why don't I share idle Gpu-z screenshots for both stock and your 0mv?

Thing is performance with your bios is awesome. I do want to stick with and further optimize it :-)

The RAM timings which the Stilt's ROM has you can mod to your original ROM, should equal same performance and if you can clock higher on original you may see a performance boost over Stilt's ROM.

On a Tri-X 290 ref PCB I saw no loss or gain in OC headroom using his ROMs, I preferred his ROM to stock factory and just couldn't be bothered to mod the original one when his was there to mod clocks, etc how I wanted.

So here's 2 shots of GPU-z. both are in idle-state.


The stock VDDC is .40mV higher. You think that's making a difference? I'

Hello.

I was Googling around for a bios update for my Sapphire Tri-X R9 290 OC Then i stumbled over this post.
I notised that one of the cards is using a older bios 015.042.000.000.000000 The other card is using 015.044.000.011.000000
So i was wondering about Flashing the "older" bios to the new bios on the other card.
Then i find this page and you made som other bios to this cards What will this bios do ?
My Rig is water cooled so my cards have ok Temprature. (Ek-Costume Loop)
I used Gpu-Z to see information on my cards.

My system is
32 GB Mem.
I7 Extreme
2 * Sapphire Tri-X R9 290 OC In corssfire.

Mean is the any point of the upgrade ? i just Ask. wink.gif
Will the fixes be better for mye Crossfire solution ?
What are the Fixes ?

Kind Regards Håkon

Generally the bios version doesn't matter much, it can be downgraded without any issues. Before flashing you should check that your card has AMD logo (in white silk screening) on the PCI-E connector / finger. If there is no AMD logo on the card it means that it is not fully based on the reference design, and these bioses should not be used. Your current bios version sounds too new for a reference card, so better double check.

I tried the 0PM for 1000/1250 and it wouldn't boot. I have a reference gigabyte 290 and it does have the AMD branding on the PCIe. I'm not sure what the issue would be, though. Trying to find a bios good for low leakage, I have a 69.2% asic.

Okay, so apparently it does boot, it just complains because of the UEFI while the card isn't UEFI compatible itself..

Is there any way to get the VRM and memory tweaks on an otherwise stock bios? Stock fan control and clocks and such.

Hello
And thank you for your reply.

I havent checked the card yet. im in the process of changing my loop. redface.gif
I will take som pictures to see soon.

Thank you

Thanks for ur work.

Works great on 290X TRI-X - 1075/1375(+25).

I stumbled on this thread while researching VRM temperature problems. I am happy to report these BIOS work great on my XFX R9 290 DD with Elpida RAM. I am using the M0PM.bin = ±0mV offset, 1050MHz / 1375MHz version. They have lowered the idle GPU temps and VRM temps by a couple of degrees. Also, they allowed my card to run with a significant memory overclock for the first time, although I have never tried pushing memory clocks very far. My 3DMark scores would plummet with even a 15 Mhz increase and the consensus seems to be memory overclocks are not worth much. However, in Firestrike I scored 200 more points at 1050 MHz with this BIOS than 1060 MHz did on the stock BIOS.

Curiously, I thought I read at some point in that the XFX DD's are reference PCB cards, however the PCB does not have an AMD logo on it. I probably should have verified that, but it seems to have worked out in any case. I would like to thank The Stilt for his work on these BIOS.

One question I have, and feel free to chime in, when using a BIOS with increased voltage, would Afterburner reflect the increased voltage on the sliders or would it start at zero? For instance, if one were using a BIOS with +25mV, and set Afterburner to +25mV, would the total additional voltage be +50 mV?

Afterburner will show the offset present in the bios, so what is shown in Afterburner is the total effective offset (e.g. 25mV).
