Avec c'est bios possibilité de ~1300MHz et + en Water

Shamino a écrit:: This BIOS let you use up to 2.0v via GPUTweak. I don't recommend over 1.55v though with a good watercooling system. And only for short period such as benchmark runs. LN2 cooling can take more than 1.6v for sure.

Pt1: Has Voltage drop, meaning that if you set the voltage at 1.4v, under load it will drop to around 1.36v

Pt3: No Vdrop, so at 1.4v, it might give you 1.42v under load.

The Stilt de Overclock.net (MLU bios builds for 290X) a écrit:: 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

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).

R9 290X Power Consumption Estimates:

- These values represent scenes of maximum load & power draw (ex: 3DMark, Farcry 3, Furmark)
- The fan uses between 2-20W depending on speed.
- All other instances including typical gaming power usage is always less, these are only maximums.
- Default: 8pin = 150W, 6pin = 75W, PCIE = 75W. Overvolted: (up to) 8pin = 400W, 6pin = 250W, PCIE = 125W
- Maximums, not averages.
- Wattage is affected (in order from most to least) by Voltage, Temperature & Mhz
- Wattage can always momentarily spike 25% higher than what you see here.
- Safe limit = 525W and/or 1.45V

PT3
Vdroop - it's ~.02-.075v depending on load & voltage. It's a percentage of VDDC.
PT3 on has 1 predefined LLC setting for OCbios (maximum)
1.225v set + LLC, Vdroop = .025v, actual = 1.25v.
1.3v set + LLC, Vdroop = ~.033v, actual = ~1.33v
1.45v set + LLC, Vdroop = .070v, actual = ~1.52v.
1.5v probably spikes up to 1.6v
1.6v+ set = blow your card up territory

ASUS
Asus.rom Vdroop averages (this depends on silicon lottery, temps, ASIC qual, scene rendering difficulty, board quality, chip leakage, etc)
1.2v set = 1.175v
1.3v set = 1.27v
1.35v set = 1.28-1.29v
1.412v set = 1.299v (spikes anywhere up to ~1.35v)
1.5v set (if possible) = 1.299v - 1.35v
Since Asus bios has TDP throttling, depending on factors mentioned above voltage is equalized around 1.299v after Droop

PT1
PT1 would equal Vdroop to Asus.rom since LLC is not modded, but unlimited TDP & voltage setting so max limit is higher. EX:
1.2v set = 1.175v
1.3v set = 1.27v
1.35v set = 1.28-1.29v
1.412v set = 1.36v
1.5v set = 1.42v
1.6v set = 1.5v
1.7v set = 1.55v OCP mods & Hard mods are needed for more headroom at this point
voltage can always equal what you set, so for PT1 setting 1.5v in GPUTweak would result in voltage oscillation in a range of 1.42v-1.5v

290x ref pcb nphase vrm is overloaded at 559.5 watts according to specifications, while the Asus bios stop at 468 watts. Uber & silent throttle you before 350w TDP threshold is reached, so if you go somewhere between 350w-468w, it's only due to power surging or tinkering voltage on ASUS bios. 1320mhz/1390mv 45/60c is probably somewhere between 400 to 500w. (Low temps = less power) ~580 watts & beyond is torture to the system - way out of spec. PT3 in theory would let you overload the card from 559.5w to ~725w or beyond. But it'll likely fry somewhere around there anyway. The stock blower cooler stops you at 265w-300w, AMD silent & uber stop you at ~300w & ~350w respectively, ASUS bios at 468w, the buck controller stops you at 559.5w, the pcb stops you at ~580w, PT3.rom (PT1 also) stops you at ~725-800w. I suppose beyond 1.45v is diminishing returns on overclock without LN2 cold temperatures.

By comparison the highest clocked GTX 780 reference card on full cover block I can find (OCN member KarateF22 1520mhz/1550mv) shows that NV OCP & OVP is active & hardware monitored up to ~572-580w. There are claims of Titan/780 ref >600w bioses, but that would only be possible with OCP mod. Remember that using PT3.rom isn't going to stop a R9 290x at ~580w like hardware OCP stops Skynet's vbios on 780 @ 572w. Therefore, PT3.rom is much more dangerous than most 780/Titan vbios @ OCN in regards to permanently damaging your video card since protections are bypassed..

VRM temperatures are an important limiting factor in overclocking and may very well be accurate, but it must first be validated using an Infra red thermometer gun pointed at the back side of the PCB. Then you must read GPUz's VRM temperature and check that it matches #s seen on your IR gun (give or take 2 or 3 degrees). Theres always the good old fashioned way of touching it and feeling the burn. tongue.gif GPUz has two VRM temperature readings, one of them is the memory voltage nphase's mosfet, the other is the core voltage nphase's mosfets. Once you start overclocking, the hotter of the two is usually from the mosfets regulating core voltage. Particularly true in the 290X's case since at this moment we aren't messing with memory overvoltage.

Concerning 3D clockstates:
When you punch numbers into GPUTweak voltage slider it represents a target voltage that you wish to have. Depending on which of the 3 bioses you're using, the actual voltage as measured by a digital multimeter will read 3 different values compared to what you've set in GPUTweak. JJJC_93 has shown this for us since he has already done Vcore & Vmem measure on DMM with PT3 bios - i linked both of these in the OP. Let's say for example you set 1.412v in GPUTweak as your core voltage. Using ASUS.rom bios (GPUTweak at 1.412v) your actual core voltage is somewhere around 1.299v (as shown by both Paulenski & overclockfrance) and using PT1 bios your actual voltage is ~1.350v; finally using PT3 bios your actual voltage is close to 1.49v (shown in multiple posts at hwbot.org). However, in each scenario GPUTweak setting is still 1.412v, and I'm unsure of what its graph would read. GPUZ will have 'more realistic' measure of the voltage that would match the actual vcore. GPUZ with PT1 may read either 1.412, 1.36v or between & PT3 may read 1.412, 1.49v, or between. In the case of ASUS.rom bios, while GPUTweak reads 1.412v, Gpuz would show ~1.299v (and perhaps it would spike to 1.35v) I don't have a 290x to test - you will have to test it for yourself as Paulenski has and take screenshots to help prove or disprove it. Since GPUZ can show 'max', that 'max' value can misleadingly represent a spike that only occurred momentarily over an extended period of high load. You will need to view 'average' or carefully look at the graph while mousing over points in time coverage to see what your average or constant voltage readouts were. Or you will need a digital multimeter & Vcore measure point to verify that GPUTweak, GPUZ & your actual voltage shown on the meter measure up concurrently or as you've said, provide 'accurate readout'.

Afterburner is coming in a couple days or less. Unwinder says maybe after the weekend. All the normal bioses that come with 290x cards out of the box will throttle at total board power consumption under 460 watts because all bioses except PT1/PT3 limit power. IMO, judging by OC results thus far, AB + stock bios + 1.3-1.4v will make for overclocks of ~1225-1295mhz. It also depends somewhat on what MSI AB allows for maximum voltage. It will be interesting to see if Afterburner cooperates with PT1 & PT3 bioses, and what actual voltages end up being when changed. GPUTweak does suck.. Regardless of which software you prefer to use for overvolting (I prefer AB over GPUtweak), I think 290X will require a bios granting unlimited TDP for clocks of 1275-1350mhz. If you're really lucky on the lottery & have super cool temps, maybe >1350mhz.
