Re:NVIDIA BIOS Editor (NiBiTor) v4.5b software and give feedback? - 2008/09/19 15:58Hi, is it possible to add support for the GeForce 9600M GT in the NiBiTor because the latest version doesn't recognize it. Just for reference it is clocked at 500/1600MHz with the shader at 1250MHz and comes with 512MB of GDDR3 memory. I have attached my BIOS file for your help. Thanks. Acer GeForce 9600M GT 512MB GDDR3 Edition - Memory : 512MB - Bus Type : PCI Express

Re:NVIDIA BIOS Editor (NiBiTor) v4.5b software and give feedback? - 2008/09/21 06:34I successfully edited my BIOS with the latest NiBiTor release and flashed my BIOS, but I got a black screen even after I uninstalled, swept and reinstalled the latest NVIDIA drivers. Is it common for this to happen when you attempt to add a fourth profile? I'm going to try with just the three profiles, but just so you know, the fan speed IC settings are available for the GeForce 9500M GS, but the basic temperature settings are still grayed out in your latest version, so please take these two tidbits into consideration for the upcoming releases. Keep up the good work!

Re:NVIDIA BIOS Editor (NiBiTor) v4.5b software and give feedback? - 2008/09/22 19:31Hello, first of all, it would be my pleasure to personally thank NiBiTor creators .Thank you very much for your work. I was using this wonderful utility for a long time, but now faced a problem. I bought new notebook, an HP Pavilion dv5z with GeForce 9600M GT having 512MB DDR2 memory inside and latest NiBiTor v4.5b doesn't support BIOS.
I am not alone in this problem, about 4-5 guys I know have the exact problem. Actually, as far as I know, no utility can edit or dump BIOS of this card. Standard clocks are 500/800MHz with shader running at 1250MHz. I hope that you will kindly add support of this card in next release. Waiting for anwser.

If you can't backup the BIOS there is not much we can do, an dyou shoudl be able to backup the BIOS with NiBiTor even if the card is not yet supported, though try as well via GPU-Z and via a bootable DOS media using nvFlash. And yeah, all cards actually are supported to backup the BIOS as that is just reading out the BIOS, unless it is integrated in the system BIOS which can be for some laptops. Once we have the BIOS we can actually add the needed support to interprete it so it can be tweaked.

The HP BIOS for notebook is actually updating BIOS of GPU, its 100% sure. As the update from their website lists it in the system BIOS release that also the GeForce 9600M GT BIOS will be updated with it. What are my chances in this case?

Re:NVIDIA BIOS Editor (NiBiTor) v4.5b software and give feedback? - 2008/09/23 03:42I have spent some hard time with fan controling on my GeForce 8800 GT, and here are my results. The ADT7473 does not work as described, the THyst value does not really act as an hysteresis during normal fan control. It does not interfere during automatic speed mode, and is an early threshold for TOperating when using dynamic speed.
It is an hysteresis only in these cases, once the temp exceeds TCrit, fan will remain 100% until temp is less or equal TCrit minus THyst. If fan is allowed to switch off, it will do so when the temp is less or equal TMin minus THyst. The fan will reset at min duty cycle after Tmin. Allowing fan to switch off is controled through enhanced acoustics register 1. By the way, my original BIOS won't allow that.
About dynamic speed, I had to study datasheet, as anyone on forums seems to have an idea on how it really work, particularly with TLow and THigh. Even datasheet reveals some inconsistencies. As long as the temp initially remains under TOperating minus THyst, fan is operating like in automatic speed, with the current initial values for TMin, TRange and min duty cycle.
If the temp is between TOperating minus THyst and TOperating and growing fastly enough, TMin will decrease, increasing fan speed versus temp relationship. Other way, fan will not accelerate if the temp does not quickly increase in this range. If the temp is above TOperating, TMin will decrease.
All these decrease in TMin will be permanent if we do not increase it when colder. That the point of TLow, when the temp is less or equal TLow, TMin is increased, decreasing fan speed versus temp. A good value is between original TMin and TOperating minus THyst. I set mine to TOperating minus THyst. The THigh kicks in here too, to prevent TMin from growing too much, TMin is not allowed to go bigger than THigh. A good logical value for THigh is initial TMin for example.
Comparisons between the temp and TLow and THigh are generating interrupts, but they apparently are not managed by GPU, threshold in main temperatures tab are there for throttling. I hope I am clear enough, English is not my native language...

Thanks for the details, though I don't see how this is feedback on NiBiTor as we just allow you to change the values if the operation is not working as you or other think that is something we can't do anything about and only NVIDIA will. Secondly the BIOS is not the only controlling factor, but just the base one. But again I don't get the means behind rather than you sharing your findings on how the fan speed control worked for you and there is nothing we can do about, we just give you the means to change these.

Re:NVIDIA BIOS Editor (NiBiTor) v4.5b software and give feedback? - 2008/09/23 10:25As you said, I was sharing the fan speed control mechanics, firstly configured by BIOS. My aim is to increase quality of comments prompted by NiBiTor, which are imprecise, for example.
Current Comments on Fan Speed... The fan will start at 30%. If the temperature exceeds 68°C it will increase with the temperature and reach 100% at 101,6°C. After the temperature drops below 64°C, it will run at 30% again. If the temperature exceeds 108°C, the fan will run at 100% until it drops below 104°C
Updated Comments on Fan Speed... The fan will run at 30% again when temperature is less or equal 68°C, not 64°C. And you may also add the description for TLow and THigh effects as it's all ready done for other values. Cheers.

Okay thanks, and we will see what can be done but this would be really low priority as there is more important things to be added. But it is good to know and we will see when we can do something better for the comments.
