i haven't seen any issues with that while being in game, max clockes all the time.

Yeah, I was asking because that's what was reference in the OP. That Max Performance should be enabled as opposed to Adaptive.

Random question to do with the power management having to be set to High Performance with these custom bios, what happens if I don't? Will it just behave as a normal GTX970 when boosting etc.. and just not hit quite the Overclocks or will it be broken as all hell or something?

Reason I ask is that I want to put a custom bios on it however I don't want to break my card if I ever decide I want to not have it on high performance (or forget to).

In reality, there is no real benefit form making the card run at max clocks 24/7.

If you fiddle with the voltage/boost tables and power limits you can set the card to run at max boost any time the card is under load without fail.

Since it doesn't appear that "jonny30bass" is posting in this thread anymore, I want to ask for opinions on this BIOS Mod ROM for an MSI GTX 970 Gaming 4G.

 

The only changes to the stock ROM are:

 

   a) Temp Target = Max Temp Target (91)

 

   b) Changed Voltage per jonny30bass' OP to 1.2831V (my voltage). I read in a post his voltage was over 1.30V, but the max voltage in the stock ROM was already at 1.2831V in the upper 70's of the Voltage Table.

 

   c) Changed values in Power Table tables 1, 3, 4, 5 and 6 to match jonny30bass' settings.

 

GPU-Z had reported Perfcap Reason = "VRel.VOp" when running Heaven 4.0 using the stock ROM.

 

The goal is to remove the power limitations and determine the optimal overclock settings with MSI Afterburner afterwards.

 

The Nvidia driver Power Management Mode is set to Adaptive.

 

The video card is also connected with (1) 8-pin and (1) 6-pin PSU cables.

 

Before flashing this modified ROM, does anyone see any problems with the settings above ?

Yeah, your voltage table is horrible. Voltage range from 1.281 to 1.281 from CLK 36 on up? Need to smooth that out a bit....there's no reason for that.

288 watt power limit may not be enough for 1.281v....if you want to run that kind of voltage, you'll likely need to raise it more.

Are you on air or water? If you're on air, the increased heat from 1.281v may cause a net negative in overall overclocking headroom because of the core temp increase from the voltage increase.

This is a copy of the bios I made for my 970 FTWs. I would model this long before I used what you have there.....

And I certainly wouldn't suggest over 1.275v for air cooling....you won't be doing yourself any favors there.

Vellinious,

 

   I noticed the error on the Voltage Table late last night.

 

   So from 35 to 74, the minimum voltages will be the stock values and the maximums will be 1.2831V.

 

   As for cooling:

 

      1) The stock cooling system was removed.

 

      2) The thermal paste was replaced with Gelid GC-Extreme Thermal Compound.

 

      3) The VRMs have Enzotech MOS-C1 heatsinks.

 

      4) The memory modules have Enzotech BCC9 heatsinks on the front and BMR-C1 heatsinks on the back.

 

      5) An NZXT Kraken G10 was modified to use only the ring that goes around the water pump.

 

      6) The pump is from an NZXT X41 AIO in a push / pull configuration.

 

      7) The radiator has (1) Phobya 20mm Radiator Shroud on each side of the radiator.

 

      8) The fans were replaced with Akasa Apache 140mm fans.

 

      9) The copper plate on the water pump was sanded down flat.

 

      10) Cool air is pulled in from the outside and is pushed down the length of the VGA out the back of the case with (2) adjacent PCI slot blanks removed.

 

      11) The front panel was cut out and the center was replaced with modder's mesh to increase airflow.

 

      12) The radiator fans are GPU temperature controlled with a Corsair Link Commander Mini for PWM fan control.

 

   I had started to build a custom exhaust blower that would have been positioned next to the PCI slot adjacent to the VRMs. However, since the GPU generally peaks around 41C, even under GPU stress tests, it hasn't been installed.

 

   For 1.2831V, how do you calculate the appropriate power limit ?

 

   As for choosing the optimal voltage, I'm using the maximum values that were shown in stock 74. If the extra voltage doesn't provide a tangible benefit, it'll be dropped to 1.275V or lower.

 

   Attached is the updated ROM with corrected Voltage Table, Temperature Target and Power Table.

   For 35-74 on the Voltage Table, should the minimum to maximum range be narrowed on the low end and widened on the high end ?

 

   And did you mean to attach a ROM file ?

Yeah, sorry. Thought I did.

The voltage range on the high end should narrow.
post #678 of 706

Vellinious,

 

   The minimum voltage column is now narrowed back to stock values.

 

   How did you calculate your Power Table to be 379 Watts for 1.275 V on a GTX 970 ?

I didn't. I tested, over and over and over again, until I came up with values that would allow me to run my highest clocks without hitting a power limit perf cap...added 10% to that, and used that for my top value in the final file. I knew exactly where my cards would hit the PWR perf cap, and could recreate it at will....to illustrate what a power limit throttle is, for those that didn't know. I think I went through 80 or so variations before I had my cards operating optimally. But, in the end, they gave me some of the highest scores that came out of the 970s.

When I told you I thought your values were a bit low for the voltage you were going to run, it was just from experience in dealing with my cards, and others that I've helped with their bios files.

Hey guys,

 

So I am in the process of optimizing the PCIE-PEG power Tables ( Table 4 and 5 In Maxwell Bios Tweaker) for my Titan X and I am wondering what suitable values would be. Mine are currently set as the below image.

 

 

 

Any ideas ?
