Hawaii XT A0 (ASIC Rev. C9x) MLU Bios for MBA C67101xx board designs

SMC Firmware Revision 15.18.00
Sequencer Firmware Revision 1.45 (ASIC dependant)
GDB 015.045.000.010 (UEFI)
CL 1032885
Hynix AFR 2Gb and Elpida BBBG 2Gb Only!!

Changes:

- Optimized VRM configuration (lower switching / conduction losses >> improved efficiency / thermals)
- Optimized memory timings for SKHynix 2Gb AFR and Elpida / Micron 2Gb BBBG
- Improved power and thermals at idle (non-gated) **
- Improved power figures in LP state (DPM1) through better balancing
- Automatic voltage offset options available -25mV, ±0mV, +25mV, +37.5mV, +50mV (build specific)
- Adjusted engine and memory frequency options available (1000e/1250m, 1000e/1375m, 1050e/1250m, 1050e/1375m, 1075e/1250m, 1075e/1375m)
- Maximum GPU VDD 1.36875V, VDDCI 1.14375V
- The fan curve is based on a look-up table instead of "Fuzzy Logic" algorithm. The curve has been optimized for the MBA cooling solution, so altering the curve might be necessary on other configurations.

** Results in slightly higher power-gated (deep sleep) power consumption.

Notes:

- TDP Limit 104-312W (208W ±50% through PowerTune, default)
- Reset AMD Overdrive settings and delete AfterBurner profiles prior installing any of these bioses

Important:

Memory straps are active only at the exact nominal frequency of the bios build. On builds defaulting to 1250MHz MEMCLK any other frequency than 1250MHz will init the strap change. At 1249MHz the MC uses strap intended for 1250MHz MEMCLK while at 1251MHz strap for 1375MHz MEMCLK will be used. This will increase the latency significantly. Bios builds defaulting to 1375MHz MEMCLK contain two identical straps which makes the memory latency perfectly linear (1250-1375MHz).

Hawaii MC strapping:

- 150-400MHz
- 401-800MHz
- 801-900MHz
- 901-1000MHz
- 1001-1125MHz
- 1126-1250MHz
- 1251-1375MHz
- 1376-1500MHz
- 1501-1625MHz
- 1626-1750MHz


Build Catalog: Warning: Spoiler! (Click to show)
** 1000e / 1250m **

25M.bin = -25mV offset, 1000MHz / 1250MHz (engine / memory)
0PM.bin = ±0mV offset, 1000MHz / 1250MHz (engine / memory)
25P.bin = +25mV offset, 1000MHz / 1250MHz (engine / memory)
375P.bin = +37.5mV offset, 1000MHz / 1250MHz (engine / memory)
50P.bin = +50mV offset, 1000MHz / 1250MHz (engine / memory)

** 1000e / 1375m **

M25M.bin = -25mV offset, 1000MHz / 1375MHz (engine / memory)
M0PM.bin = ±0mV offset, 1000MHz / 1375MHz (engine / memory)
M25P.bin = +25mV offset, 1000MHz / 1375MHz (engine / memory)
M375P.bin = +37.5mV offset, 1000MHz / 1375MHz (engine / memory)
M50P.bin = +50mV offset, 1000MHz / 1375MHz (engine / memory)

** 1050e / 1250m **

25P.bin = +25mV offset, 1050MHz / 1250MHz (engine / memory)
375P.bin = +37.5mV offset, 1050MHz / 1250MHz (engine / memory)

** 1050e / 1375m **

M0PM.bin = ±0mV offset, 1050MHz / 1375MHz (engine / memory)
M25P.bin = +25mV offset, 1050MHz / 1375MHz (engine / memory)
M375P.bin = +37.5mV offset, 1050MHz / 1375MHz (engine / memory)

** 1075e / 1250m **

25P.bin = +25mV offset, 1075MHz / 1250MHz (engine / memory)
375P.bin = +37.5mV offset, 1075MHz / 1250MHz (engine / memory)
50P.bin = +50mV offset, 1075MHz / 1250MHz (engine / memory)

** 1075e / 1375m **

M25P.bin = +25mV offset, 1075MHz / 1375MHz (engine / memory)
M375P.bin = +37.5mV offset, 1075MHz / 1375MHz (engine / memory)
M50P.bin = +50mV offset, 1075MHz / 1375MHz (engine / memory)

All of these builds have full ASIC configuration enabled (44 CUs, 4 RBs / 64 ROPs).
The memory timings are optimized slightly more towards gaming scenarios than before.
The overall latency is tighter, however this timing set wasn´t used for mining simply because there was no additional performance improvement.

ps. I won´t be making any additional builds (unless there are issues with these), so don´t even bother to ask.

I really couldn´t care less if these builds don´t work for you.
If you got issues with them, revert back to the original bios.

Compatible cards: Reference MBA cards, early TUL (PowerColor, Club3D, VTX3D, Diamond) cards and probably early Sapphire Trixx revisions based on MBA design.
Certainly not compatible: ASUS DC2 and MSI Lightning cards.

Use the included ATIFlash to update the bios (DOS).

This is pretty cool. I'm going to have to try these out. Wonder if my Sapphire BF4 editions will work (Epilda mem).

The cards based on the MBA (reference) desing can be identified based of the white silk screening on the PCI-E connector.
Unless there is a AMD logo and part number silk screened on board the card is not based on MBA design but on a ODM custom design instead.

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 85

All of the bioses contain support for Hynix and Elpida modules.

All 290X cards should have dual bios available, so trying them won´t basically cost you anything even if it doesn´t work for your card.

My custom loop would need to be drained to check the pci connector, but I'm pretty sure the 2 Bf4 editions are MBA thumb.gif

These flashed perfectly. Running 1075/1250 +.25v and everything is running smooth! Thank you Stilt!

I loaded this on my quadfire 290x, i am currently using the 1075/1375 +50mv version. while i havent noticed anything outside having higher clocks it seems to be nice and stable so far. i like having the extra boost without having to use 3rd party tools and get a slight bump over just running stock.




I will give these a good testing. thumb.gif

+rep for OP

Anyone able to post a GPU-Z screenshot?

Preferably one of the 1075/1375 builds.

Cheers
Mat
