    Ok, but maybe 20 % is still ok. 30%=2500rpm...default is 40%, won't go under that. An aftermarket fan would cost me about 25(second hand, very rare)-50% of the price of the card. If I can't make it quieter, I would rather put another 25% of the price and get a 560GTX, not a quieter 465gtx. Thank you. Didn't have instant notification enabled , sorry for not answering

    Any news On If anyone found the Inno3d GTX 470 bios? Can't we just find someone who bought one and have them upload their dump .bin for us?

    I'm interested in it since I believe it has a revised fan profile on top of the (OBVIOUS) differences in it's non-reference Cooler and all.

    By Stock the Fan Profile will let the GPU EAT WAY UP INTO THE HIGH 90s! :3eyes:

    Thanks

    Just use Afterburner and create your own profile with the heat/noise balance that suits you.

    Yeah I just wish I could make my own profile. Since the stock built in profile is terrible.

    I tend to not like the noise above 75% so I leave it at 75% at 75C and it doesn't seem to go past 80C at 810Mhz Core 1620Mhz Shader from 607Mhz... :)

    If someone finds the Inno3d GTX470 bios .bin or .rom (Ultimate PWM Fan Profile) please let me know! :)

    You can make a custom fan profile in settings in afterburner....click settings and then click the fan tab and make a custom profile....as the guy above me said...I think your misunderstanding what we are telling you to do.

    I know exactly what your talking about.

    What I think is you don't know what I'm talking about. I thought I was clear enough, I suppose not.

    Anyway have you ever modded the VGA BIOS of a GTX 200 series on Nibitor? If so you would know that within Nibitor you can setup a COMPLETELY custom FANSPEED IC profile for the video card written directly into it's VGA BIOS. From there I can set a nice profile that has tmin of 40C and a tmax of 68C and a maintain parameter of 65C. At that point the video card wouldn't kick the fan on until it hit 40C and from there as the temps rise to 65C it will use the required fan rpm to maintain 65C without going Wide Open Throttle. Then once it exceeds 65 and approaches or exceeds 68C the fan will go to 100% until the temps dial back to below 68C.

    I want to do the exact same thing to a FERMI, however I don't think it's possible. But I did noticed Inno3d GTX470 does in fact have a custom made profile to maintain lower temps which they built from an unknown application.

    Thanks cya

    I appreciate that but I already looked there and the GTX470 is missing.

    Thanks

    Hi

    I have SLi EVGA 470 FTW H20. Can I mod the bios so I can up the voltage past 1087 in Afterburner? There is a slight difference in the bios verisions of the different cards. One was returned to EVGA under RMA and they sent a replacement....

    The bios are

    http://www.mediafire.com/download/hoclwo1s7953bgc/GF100_FTW2.rom

    http://www.mediafire.com/download/bp1oci8d83x94df/GF100-FTW1.rom

    I've always thought the voltage lock is what holds the cards back from a bit more umph!

    Any help would be greatly appreciated.

    Simon.

    I'm thinking under water I could up the clocks from the 829, 1998, 1646 I've got them at now.

    Any help would be greatly appreciated!

    Create yourself a windows 98 boot USB Flash drive. Put nvflash on there. Then boot to the flash drive and copy ur modded 2 bios.rom files to the usb flash drive root. nvflash.exe needs to be in there too.

    Here is Fermibioseditor, nvflash, usb win98 boot tool, nibitor, etc
    http://www.mediafire.com/?h12jicl2j3c2udn

    Here's your MODDED bios and stock in there too...

    http://www.mediafire.com/?wwupo2d52zy69dx

    You can flash both gpu's in one go before reboot on win98 nvflash.

    rename ur modded bios.rom's to 470bios1.rom and 470bios2.rom

    type nvflash 470bios1.rom -5 -6 "PRESS ENTER"

    confirm id's match etc then press "y" wait say 30 seconds and it'll say completed.

    type nvflash 470bios2.rom -5 -6 "PRESS ENTER"

    confirm id's match etc then press "y" wait say 30 seconds and it'll say completed.

    Remove flash drive and reboot to windows. Done!

    bios.rom is the filename your flashing so u can rename the modded bios.rom to 470bios1.rom and 470bios2.rom

    nvflash will flash the gpu's according to gpu id so it'll flash the correct gpu with the bios specified.

    You have to figure the clock generator multiplier for the fermi 470s. It goes like this say you want the clock u set it bios to actually run at that speed in windows. Sure GPU-Z will see whatever u set in the bios but it won't actually run that speed because it's up to the clock generator to do that.

    So basically the clocks you can get go like this u can get 810Mhz, 835mhz, or 851mhz. You can get 851 on 1.112v on air but the voltage regulators run over 100C. They run close to 100C stock anyway. It's the paint on the metal heatsink that contacts then which actually insulates its own temperature therefore restricting heat exchange from the regulators/ memory to transfer heat to it. You can get 835Mhz on air no issue at all at 1.062v.

    I'd recommend stock memory clocks since unless u hard volt mod the board anything above stock usually isn't 24/7 unelss were talking about 25Mhz.

    I also reduced the 2d voltage from 0.875v to 0.862v which may yield a solid decrease in idle temps and power consumption.

    3d voltage is at 1.112v and max table voltage is at 1.112v. Maybe I should have increased it but I have found anything above 810mhz via evga produces instability. Only modded the bios directly allowed for stability at 835mhz and 851mhz on air of all things too. I hit 86C on War Thunder and I bet the vregs were above 100C. On all other fps I hit 81C at 1.112v 851Mhz.

    I could provide more info later if u wish.

    I modded my cooler got as much paint as I could off. I need to find a shop locally that has a glass blaster to get it off. I used a high speed electrical wire wheel brush to get this much done. It reduced my memory/ voltage regulator temps by about 25-40C depending on the load! There's a gasket around the GPU Core Contact which I removed. It allowed for about 5lb more torque on the core which yielded about 10C drops as well on the core! The paint needs to be removed if u want SUPERIOR temps and STABILITY out of the FERMI GTX gpu's...

    clocks on both cards are what I have found to be 100% stable as long as your cooling your voltage regulators and memory to the max. I left memory at stock since I want u to have 100% 24/7 stability at 851Mhz 1702Mhz shader. This is the clock the fermi clock generator is happy with and all apps like Evga Precision and AIDA64 will report it exactly as it was set. Since it abides by the fermi clock generator multiplier. I can explain the mathematics.

    I have just been testing out some overclocks and 835mhz is stable at 1.062V with no droops. The FERMI multiplier is at .1875 so I could only adjust from 835mhz to 851mhz because it has to be a multiple of .1875. Basically 835 is 16 x 52.1875 so I could only jump to 851 which is 16 x 53.1875. So if you wanna figure possible clocks you do 16 x 54.1875 = 867Mhz, 1734Mhz shader. Say you want more than 867Mhz you do 16 x 55.1875 = 883Mhz Core, 1766Mhz Shader. Or if your nuts and you want more than 883Mhz, then you do 16 x 56.1875 = 899Mhz Core, 1798Mhz Shader . Maybe your completely nuts and you want more than 899Mhz core clock. Then you do 16 x 57.1875 = 915Mhz Core, 1830Mhz Shader. :wanker:

    THIS IS MY GTX470's and they run at the same speed. Anything beyond 851Mhz is possible. Just going to need huge jumps in voltage. Since jumping from 835Mhz to 851mhz required a voltage increase from 1.062v to 1.112v.

    Hy there,

    sorry for my late response...
    I changed teh voltage Limit on your 2 Bios files..its now 1.212 v. MAX.
    Why teh 2 Bios´s have different size i cant tell u, maybe they changed something.Indeed, by looking at the bios again, u can also see on the pics, that the one card has an different (newer) Bios on it, thats why the size is different. i think u should check if theres an bios update for the other Card u have, so they are identical.

    Please be carefull with it..dont use more then u need for stable clocks, and dont let it get to hot ;)

    The 465 is basically a slower cooler version of the 470. You can only mod the fan profile in evga precision x or another like it. Set 1000ms interval update, 0 hyst. force update, 0 degrees Celsius at 0% fan and 75 Celsius at 100% fan speed. Or 85 degrees Celsius at 100% fan speed. Make sure the curve is perfectly linear for ideal noise/ temps ratio. You can set 40% up to 50 degrees Celsius, then abde by a linear progression to 100% at between 75 and 85 Celsius. Your golden.

    Is here a way to change fan speed in bios file?
    I want it to be changed when after turning on.
