svl7 Posted May 21, 2012 Share Posted May 21, 2012 You mean even with the stock BIOS? Highly unlikely. While it is totally possible for the driver to override the vbios settings, I really doubt this is the case. It's rather getting read out in a wrong way. But the only easy way to find out what's going on is to overclock the card and see whether the upper limit of the core clock is way beyond the one it was with the previous driver.

Was not able to get any higher before without artifacting or crash. This is reported in evga precision as well as GPU observer as 0.93 even Quote Link to comment Share on other sites More sharing options...
svl7 Posted May 22, 2012 Share Posted May 22, 2012 Well, if you already used the modified BIOS then your voltage didn't increase, in the modified BIOS it's set to the max possible value, and that's hardwired, the driver can't override the limits of the hardware.If you can clock higher than previously then it's due to driver improvements, that's totally possible, though 40Mhz is a lot.Would be interesting to see whether other people can observe a similar behavior with these drivers.

Nvidia has access to, and can change any behavioral parameter inclu +-v tables if they so choose in design, perhaps a hidden" 0.9125 " table or say a 1.00V=0.00V_% option that can be driver accessed and set to say 0.93..... specifically for cuda programers ???? Remember....laptop chips are undervolted, under clocked desktop chips.......all out of same barrel, just put into one of the two form-factors and adjusted accordingly.

Using which vbios and which OC program? I'll give it a shot. I'm currently using a 0.92v vbios for my 580s. Quote Link to comment Share on other sites More sharing options...

You're missing a big point here. Even though some laptop cards use the same silicon as desktop cards, the whole circuitry of the mobile cards are different, they don't even come close to their desktop equivalents, especially the high-end mobile cards. There's simply no room for such fancy circuit designs. Unlike some desktop cards, mobile cards don't come with programmable voltage regulators, the voltages are hardwired and in most cases it can only be tweaked in a very limited range.A chip doesn't just come "undervolted", it gets limited by the controlling and voltage supply circuits on the PCB.Nvidia can't just do some magic tricks and increase the voltage of the card above it's hardware limit. And also Nvidia won't increase the voltage of a card per new driver release, in a lot of systems this would result in cards running above the thermal design points of the system.And if you read "0.93V" on your 555m in the M14x, then it's simply an inaccuracy of the monitoring software. The voltage doesn't get measured, the monitoring software only displays a value it reads out from the driver or a different interface.

mw86 Posted May 25, 2012 Share Posted May 25, 2012 hi, havnt tried gpuz yet, just evga precision and gpu observer, along with a marked improvement in overclock maybe as SVL7 mentioned... we could have a few other users report if they see the same improvement with the drivers... either way the improvement has occured and 40mhz is a nice jump. Would be nice to see more users report back. Quote Link to comment Share on other sites More sharing options...

svl7 Posted June 19, 2012 Share Posted June 19, 2012 Main post updated, added two new versions of A08 (standard and unlocked) which bring back the SATA performance of BIOS A05. This allows GF116 users to enjoy the benefits of A05 as well, and brings a new option to the GF106 users who chose to stay on A05 due to the SATA behavior of A07 and higher.Enjoy. 2 Quote Link to comment Share on other sites More sharing options...
Sean Declan Midwood Posted July 16, 2012 Share Posted July 16, 2012 Thanks for the continuous updates in spite of the fact that most people's efforts are going into improving the 600m series! I also wanted to add that; since the last few Nvidia driver updates have come out all programs are reading a voltage of 0.930 volts compared to the 0.912 volts when I first started using the A08 bios for the GF116. 1 Quote Link to comment Share on other sites More sharing options...
svl7 Posted July 16, 2012 Share Posted July 16, 2012 Thank you for the feedback! Regarding the voltage I stick with my theory, the vbios didn't change and thus the voltage table didn't change either. It seems that Nvidia changed something in it's API which causes it to return a different value. I can't say whether 0.93 or 0.912v is more accurate...

sxwy6zyq Posted July 26, 2012 Share Posted July 26, 2012 THX.but why i use theM14xR1_A08_[unlocked]_voltmod_incl_GF116_&_SATA_fix.zip .it doesn't apply the sata3?Intel stronge show 3GB/s Quote Link to comment Share on other sites More sharing options...

phantasm98 Posted August 8, 2012 Share Posted August 8, 2012 I have a MSI GT780DX with a 570m in it. I read that some of the shaders are locked and was curious if there are any methods of unlocking them? Quote Link to comment Share on other sites More sharing options...
svl7 Posted August 9, 2012 Share Posted August 9, 2012 Nope, no shaders to unlock, also way off topic. Quote Link to comment Share on other sites More sharing options...
Ahanix Posted August 15, 2012 Share Posted August 15, 2012 Great work, I really appreciate you doing what others are afraid of. I'll give the unlocked A08 a flash and get back to you on what I end up with as far as OC'ing goes after I repaste my heatsinks.Thanks again Quote Link to comment Share on other sites More sharing options...

dradz Posted August 30, 2012 Share Posted August 30, 2012 Thanks, i will try your last bios. but can i use it with CPU at 95 °C and GPU at 82 °C in game ? Quote Link to comment Share on other sites More sharing options...
svl7 Posted August 30, 2012 Share Posted August 30, 2012 Nope, you'll need to clean out your system and repaste first, else you'll run into issues. Quote Link to comment Share on other sites More sharing options...
dradz Posted August 30, 2012 Share Posted August 30, 2012 Ok ! And i have another question : what's the best bios after tests ? the last A08 or the A05 ? I bought an old M14xR1 with first 555M GT 3Gb and no SSD HD so i don't see why the A08 is good for me. Quote Link to comment Share on other sites More sharing options...
