Most cards are limited by the Power Limit than Voltage.

My TXM does 1550@1.200V
980TI HOF folds 1525@1.175V

Voltage does not cure anything past that. redface.gif

My TPD is 88% @ 1660mhz / 8900mhz ram @ 1.280 voltage and thats a 400watt total bios i cant get past 88% to 90% and agree for me i get 1600mhz @ 1.200 volt for 1660mhz my card want atleast 1.275 volt so it get pretty hungry. Temps has more to say on maxwell. After 30 degress i Loss MHz i had my card going 1690mhz last Night for the first time but crashed as soon i hit 32 degress

the very very top (66000mw and 75000mw) is the pci-e slot; the next set of 3 (12000, 162000, 175000) are the two 8 pin power connections; the last 3 are the combined max power limits 150000, 275000 [changed 300000], 300000 [changed 350000]) so yeah, your "old" 109% is now the "new" 100%. MSI already had the power connections configured to provide that.

here:
GM200PL.zip 152k .zip file

there is/was some stuff in the voltage table that caught my attention:
Warning: Spoiler! (Click to show)
it's like they don't want you to hit CLK69 or higher in the boost table so i adjusted it. your card may boost differently now. as a matter of fact i ought to mention once the bios starts getting modded, it will start behaving differently. until you see how/what changes/is affected - treat every reflash as a new card.

and sorry to get picky but just post a screen shot of GPU-Z render test running like so:



don't use afterburner or PX - just run GPU-Z. i'm finding it . . .or i say it's surprising the card is boosting so low. i would think a 76% ASIC card would hit ~1410+ ~1.8-1.9 volts. and 60c for water seems a little warm, you have high ambient? keeping below ~54c gets better stability esp for benching.

thanks for the reply and the work youve done bro!
now stats....

BEFORE BIOS MOD :
+87Volt (1280mV on load max)
109 power limit
core +120
mem + 500
full load temp max 60c

AFTER BIOS MOD :
+87volt(1220mV on load max)
+116 power limit
core +140
mem + 500
full load temp max 75c

and it seems that im not going above 100% power usage either before or now...
i had all pictures in photoshop of how you asked with gpu z but photoshop crashed and gone frown.gif
my temps basically increased like hell but performance wise nothing realy, maybe 5fps boost...
also how come AB reports 4000mhz memory and gpu-z reports 2000mhz memory? always double difference.

basically i gained +20 core clock and no memory clock gain , but still crashing with 3dMARK ...

modded bios running gpu z render : Warning: Spoiler! (Click to show)

i'm surprised the operating voltage changed; the part i modded was for boost table entries so i expected just the clock speed to possibly change. on a side note; those temps are a little high for water cooling. 60c to 75c is more like air cooling. are you using an AIO or loop? i have a uniblock on my loop w/cpu and 280mm rad can run 3Dmark all day long and not go far north of 50c depending on ambient temps and stressing full system/aida64. so maybe give that a peek since cards can start voltage throttling as low as ~64c to ~72c. (this has nothing to do with temp throttling which throttles the speed but not voltage. but the voltage goes down with the clock speed blinksmiley.gif ).

before i go too far off, i'd suggest you get maxwell bios tweaker if you don't have it already and take a look at what i had used as my bios modding bible (in german so may need to translate):
https://www.computerbase.de/forum/showthread.php?t=1445972

i suggest you look around at it and glean some and familiarize with the tables for boost, voltage along with power.

but getting back . . . i should have asked for a before/after flashing GPU-Z sensors. really everything should have stayed the same but possibly increasing the boost clock by lowering the min voltage needed to go farther up the boost table. that link to computerbase will show how the voltage table CLK entries are tied to the boost table CLK entries.

that image showing 1532 @ 1.243v is not having used AB to change anything?

right now knowing default, untouched speeds/voltage helps to know what to change to OC better.

so i rebooted my PC about 5 times trying and trying to OC from zero to hero biggrin.gif ...

finally got temps to go to 60c max again . yes i have EKWB waterblock , my loop includes gpu and cpu , 2 x360rads, 1xres. loop is good.

also everything else has settled better now, including clocks.

im at 1519 core without drops
4082 memory without drops
TDP is between 100% and 109% though smile.gif but i think its ok.
voltage is sitting at 1224 v . maybe il try push core clock more later and see what happens. but is it possible to allow for more volt overclocking? maybe up to 1.3000 safe? or 1.2800? i think that would give a big boost on OC, but im not sure if that is safe for gpu or not.

just keep in mind that 109% (300 watts) is now the 100%.

two things to also be mindful at times:

boost bins are in 13mhz increments. you can see in the boost table, though a few are 12.5Mhz: Warning: Spoiler! (Click to show)
and voltage increases in ~6mv increments, though depending on the ASIC it may need 12mv to 18mv to increase a boost bin (of 13mhz). the lower the ASIC% the higher voltage it needs. ie my ~66.9% ASIC needs 18mv-24mv.

with that said, yeah you can get some more out of the card BUT a higher ASIC% card will see some diminishing returns sooner when jacking up the voltage too much unless keeping the chip under 36c; even on water myself that means a cold ambient temp day! the max supposedly set in that bios is ~1.25 (it may read 1.248 in AB) so you may be able to increase that w/voltage slider in AB, no?

when it comes down to it, 1513@1.224 is really pretty good completely game stable. its really just benchmarking that increasing more would help but nothing wrong with that.

so since my asic is 81.4% i'm actually hampering my possible overclocks by using bios settings with higher voltages? especially since i'm on stock air cooling? i did recently reseat and reapply thermal paste, i gushed a big nice glomp of Kryonaut on dat sucker
post #15190 of 15373
around 6 months* after the 980ti was release there was a few quotes floating around from k|ngp|n that 1.23 - 1.25 was about the max voltage on air/water for GM200 when scaling get's more horrid. some of lower ASIC cards i found can use a bit more, ~1.28 but yeah, if you're starting out by jacking up the voltage before increasing clock speed; you're probably doing it wrong.

* make that 2 months. i remember i had my classy then.
