I only got VDDC Offset = 37mv and VDDCI 1031 MV

This app is used only for oc.
GPU-Z shows the actual voltage, check the red indication on this picture.

Applied mods:
-Added BBBG elpida rams info table + stilt values. Correct info is showed now on gpu-z too.
-Corrected vram size and density.
-OC'ed to 1100/1300Mhz with fixed DPM values which set VDDC ~1.2V stable under load. +38mV on VDDC and +31mV on VDDCI are applied. These values are restored to 0 if you reset any settings applied by using any overclocking tool (msi ab, trixx, iturbo etc) but it will immediate lead to driver crash. Restore clocks manually and leave VDDC and VDDCI values to as written above. Expect around 13.2k graphics score on firestrike 1.1.
-Device ID and sub-vendor should be displayed correctly now on Asus r9-290dcii and Asus r9-290x dcii gpus. 1002-67B1/0 for asus r9290/x dcii respectively.
-Would be cautious if i was using it with the stock cooler.


Why to use this bios? Does not produce memory errors (as other bios do) and according to my gpu perfromance runs better with less heat on higher core clocks without artifacts/glitches.
As usual, do not blame me if this bios burn/destroy your gpu, test it on your own responsibility.
Credits should go to the starters of these mods, not to me. Click for ASUS R9-290 DCII (Click to show)

Click for ASUS R9-290X DCII (Click to show) The base file used: ASUS_R9390X. Just for reference purposes do not flash it to your r9-290(x) gpu (Click to show)


could you post a benchmark @ 1150/1450 mhz to compare with my bios?

Thanks, so how do get my voltage unlocked for more juice? i mean 100mv+ or 200mv+ is not enough for me to get stable core at 1100 example, flickering, funny colors.

@melodystyle2003 I have Amd r9 290 original PCB, my stock bios is Stockelpidabios.zip 43k .zip file

Here you go: LINK
Mind that mine is a r9 290 gpu (not x) and it runs on PCIe 2.0 x16 (not a GEN3 capable board), which reduces by ~1% the overall performance compared to 3.0 (same as yours), plus i am running the latest 16.7.2 drivers.

Something sounds not good here, have you tried with your stock bios to see how further you can push the core clock beyond stock frequencies?

Let me check it and will get back to you soon.

Nope, but I will try tomorrow wink.gif

This BIOS improves my performance by ~10% in certain benchmarks, however I'm pretty sure I have a non-reference 290x, this is it: http://www.gigabyte.com/products/product-page.aspx?pid=4885

So, as long as this BIOS works, is it safe to use it? Or would I be better off modifying my stock BIOS? And in that case, what makes this BIOS perform so well, is it just the memory timings?

Its interesting what you say, i would like to see some comparisons and also how it performs from overclocking perspective?
I attach the original bios you mentioned and the corresponding vram_info for elpida ram chips, which settings are equal to both silent and performance F2 vbios. Warning: Spoiler! (Click to show)

There is more done to the BIOS because upon flashing it mentions Grenada instead of Hawaii. And the temperatures are lower too.

Stock bios:
1125 / 1500 +25mV http://www.3dmark.com/3dm/13396932 - 4353 graphics score
1100 / 1375 +0mV http://www.3dmark.com/3dm/13397148 - 4234 graphics score. Core clock says 600mhz, dunno why
1070 / 1250 +0mV http://www.3dmark.com/3dm/13236373 - 3985 GPU score

I can also run 1150 core at +100mV but the temperature is unacceptable.

290x-elpida-mod bios:
1140 / 1450 +100mV http://www.3dmark.com/3dm/13415309 - 4524 graphics score
1125 / 1450 +100mV http://www.3dmark.com/3dm/13415445 - 4460 graphics score
1100 / 1375 +38mV ("default") http://www.3dmark.com/3dm/13373639 - 4387 graphics score.
This is only +3,6% better than stock BIOS at same settings. I saw a bigger delta before, I must have messed up the clocks.

Observations:
Mod BIOS runs cooler.
Mod BIOS has default +38mV core voltage in afterburner, why?
Mod BIOS will not do more than 1450-1475 mem. Stock will do 1550 ish. Expected due to tighter timings.
Mod BIOS will not do more than 1100 core. Increasing voltage does not seem to help at all.
Not true. It will do 1140. Reported core voltage (HWInfo) is a bit lower in this BIOS compared to stock, guessing that's why it won't do 1150.

I will experiment some more with the modded BIOS, probably post later today. updated post
