Hey guys..
I got one of the first batches of these cards in my D900f, so i probably have an outdated bios (62.92.83.00.0e). Its not that anything is wrong with it - i can overclock it way higher than the 285m clocks and temps are amazing (42C surfing the web and never over 58C playing any game - always overclocked), but i was wondering if any of you has a newer bios if its perhaps better in some way, and what program could i use to change my bios to have it run the clocks of 285m without the software overclocking with nvidia performance? Or perhaps even if someone has time to compare the 280m and 285m bioses to see if everything else except the clocks is the same - than perhaps i could just flash over the 285m bios?

Hey,
So youre saying everything except the clocks and timings is the same?
So the 285m bios would work on this card - if yes can you upload the 285m bios with the original 285m clocks and the timings of 280m?
And which software do you use to modify and flash the bios onto the card? -

There are a few other minor differences, but yes, other than the clocks, the timings, and the manufacturing quality of the card, the GTX 280M and the GTX 285M are identical. However, I cannot guarantee that the GTX 285M BIOS will work on the GTX 280M. There are a few details that I am investigating that is allowing me to state this.
I am unwilling to upload my copy of my GTX 285M BIOS, sorry. You will need to ask another GTX 285M user to upload it for you.
Use GPU-Z to extrapolate the GPU BIOS, NiBiTor to modify it, and nvFlash to overwrite your existing BIOS. -
Allright, thanks for the info, ill probably just flash the clocks to the stock 285m values, and one last question..
is there any reason why they dont round up the clock values (for instance instead of 585/1463/950 - 590/1460/950)? -

Nvidia always keeps the core/shader clocks linked. For the G92, it's a 1/2.5 ratio, which ideally grants the most stability.

i could provide you with a newer GTX280M bios
i have two versions at hand:
62.92.91.00.01 dated 05/18/09 and
62.92.91.00.02 dated 05/27/09
with the only difference being that the .02 has the 2D-Voltage lowered to 0.85V (.01 has 0.9V)
i could also integrate overclock or voltmod if you wish -
Ya still with my 583/1450 they misscalculated
Thanks ill keep that in mind when setting the clocks.. probably round them up to exactly 1x/2,5x. -
If you could send me the modded first one to have these clocks: 600/1500/1000
that would be really nice
-
Soviet Sunrise Notebook Prophet
The clocks are close enough to each other. It really not going to matter much if the deviation out of reference ratio is by a few Hz.
-
I though so ya.. i just like nice round numbers though
How far would you push the memory though? I tested 950,1000 and 1050 and saw almost no difference in crysis and 3dmark.. -
there you go

Nvidia's reference clocks for the GTX 285M are 576/1500/1020. Clevo has modified them to 600/1500/1000. With that said, even though the GTX 285M and the GTX 280M have identical memory chips, and are almost identical overall, you should slowly overclock as manufacturing quality is still a present factor. Start at 640/1600/960 and work your way up from there. I'm pretty sure at those clocks you're going to need to raise the voltage.
I would not push the memory past 1020MHz. Anybody who exceeds the factory rating for these chips are just asking for hardware failure down the road. The rule of thumb that I follow is never to exceed 102% of the rated maximum, in which is conveniently the reference clock speed for this card, so we're good. But even then, the memory still needs exceptional cooling, meaning that the thermal pads transfering heat from them to the cold plate needs to be of top quality and in top condition. -
Thanks FENNEK
Ive been running my card at 600/1500/1025 since i got the laptop.. about a hundred 3dmarks and hundreds of hours of gaming.. never had any alarming temperature or anything wrong with it so im pretty confident i can do at least 600/1500/1000... if it dies ill have a reason to buy the actual 285m and overclock that sucker
-
Fail temperature on this thing is set at 108C
-
The problem is you won't know what the temperature of the GPU RAM is because they don't have any sensors. You could overclock your GPU and be at good temps overall but your RAM might not be. I tend to leave the RAM levels alone if I plan to OC.
-
But ive been running the same overclock for months and so has anothergeek and no problems.. the ram chips are still under the same heatsink so if they heated so much i should also see an increase in overall temp right? If the core is just under 60C it cant be so bad or am i wrong? I mean its just a 50mhz overclock on the memory..

My philosophy has changed a bit since the time of my previous post, but the focus is still the same. Most non-volatile memory chips produced today are rated with a temperature tolerance of around 80-90*C depending on the manufacturer. System RAM and GPU RAM are typically rated for 85-90*C. Notebook system memory doesn't need cooling as they will never reach that temperature during operation. The hottest they are going to get, if ever, is around 70*C when stressed hard in an enclosed space. GPU memory will reach around it's max rated limit because all GPU cores nowadays share a heatsink with the GPU memory, and the GPU core is the primary producer of heat for the whole GPU component. -

108*C is the failsafe temperature. 116*C is the actual fail temperature. At 108*C, the GPU will severely downclock itself or shut itself down to prevent damage. On my card, I lowered the value from 108*C to 90*C. -

I wouldn't have the memory set as high as 1050MHz, but if your GPU core temp is staying as low as you say it is, then it's safe. -
I wont set it to 1050.. i meant its a 50mhz difference between stock (950) and what ill use (1000).
I know what the failsafe is misstyped i guess.. didnt know it dies at 116C though - thought it could die at over 100 already thats why 108 seemed high to me.. i intend to set that around 95 prolly.. -
Soviet Sunrise Notebook Prophet
At 116*C, the card dies, but on the way from 109*C to 115*C is where it begins to die. However, this doesn't happen instantaneously; only over medium to long periods of repeated abuse will this happen. The soldering on the card will become very brittle and weak if it is operating in that temperature range.
-
Thats useful to know.. so they really dont play it all that safe setting it at 108C..
-
Soviet Sunrise Notebook Prophet
I find Nvidia's downclock threshold to be really high. It would have been more reasonable to set it to 105*C or 102*C. Nonetheless, the only real failsafe mechanism is the user himself.
-
After 20 minutes (depends on ambient temps, my room is really warm) of OCCTP I manage to hit 101-102C. That's the max my card has ever reached and I have never seen it go beyond that even after 25minutes of OCCTP and I am not going to try going further as ... I really like my 280M. However, I have noticed that once it passes 98C the fps in OCCTP starts to fluctuate and I assume the card becomes unstable. For this reason I have set my downclock temps for my card to 98C.
-
Thanks for the input Blacky.
Would you maby be willing to save your oced bios file with cpu-z and upload it? Id like to check if i have everything right this time..
And did anyone try to change the OEM and adv. signon text in nibitor or could that mess something up (id like to put my own thext there just for the fun of it)? -
I would, but my 280M is MXM 2.1 which means my BIOS won't help you much. If you want, you can send me your modified vBIOS and I will double check you didn't miss something. Also if you can, provide me with your subsystem ID, you will find it under Hardware ids in your device manager for your video card.
-
Do check than please.. i think its appropriate to assume i also need 1.03v for stability or would 1v be enough (ive ran 1v till now on these clocks but if my temps never go over 60C its better to make it 1.03v right)?
280m -> 285m Bios MoD
Hardware IDs from device manager:
PCI\VEN_10DE&DEV_060A&SUBSYS_09031558&REV_A2
PCI\VEN_10DE&DEV_060A&SUBSYS_09031558
PCI\VEN_10DE&DEV_060A&CC_030000
PCI\VEN_10DE&DEV_060A&CC_0300 -
Actually you can keep the voltages to 1 as long as you don't go above 600/1500, but I haven't noticed any major difference in terms of temperature when using the higher voltage. So if you want to make sure the card is stable, I suggest you use 1.03. It depends on you.
Change the subsystem id in the BIOS to 0903.
You can put the critical temp a bit higher ... 96-97C.
Overall it looks alright.
Edit: You may also want to save the BIOS in .rom format and not .bin. I think nvflash only likes .rom files but I might be wrong on this one. -
Id rather have the card throttle down or shut down at 95C to be sure i dont get near the damage zone.. i dont expect it to even get near that temperature anyway..
And why do i need to change the subsystem id
?
And is the board id fine the way it is?
And have you ever tried to change the adv. signon text or do you think it could mess it up (experimental)? -
The board ID looks fine, it's the subsystem id which is different. It's not a major problem but when you will try to flash it will give you a subsystem missmatch error and you will have to use the force flash command in order to get things done. It's just to save you some hassle.
I have tried once to change the signon text but it doesn;t make any difference, I would leave it alone. -
Ah ok, ill change the subsystem than..
Btw.. is there any chance to change the card id to flash it to displaying gtx 285m or do i have to get my hands on a real 285m bios and flash that one on it?
If it worked to flash 8800gtx -> 9800gt it should work for this since its the same card right? -
Im sorry for posting such a retard question but can someone tell me how to flash/update the GTX 280m Bios'? Ive never done it before. Thanks much
-
Might work, you would have to change the device ID from 060A to 060F.
-
The latest D900F (1.05) bios should support it right?
-
Im still running BIOS v1.03 on my 900F. Any noted changes/improvements on this new version compared to my older BIOS? Where can I download the latest 1.05 version? Thanks much!
-
in theory, yes
Well, as a matter of fact, even if you screw up you will still be able to blind flash your card back to life.
I had to do it once... actually it was one of the first things I had to do when I got this laptop (second day after arrival)
.

Hello @ all
and @ Blacky, can you please upload your OC VGA Bios?
I have the same System, Clevo M570TU with GTX 280M GPU.
Do you think it will work with my System? -
I will PM it to you later. Yes, it should work fine. But be advised that I have also undervolted my clocks at lower clocks to save battery life. The BIOS that I have works best on my system, I cannot guarantee it will work on other systems.
-
Ok thanks I'll try it.
-
@Blacky
can you send me the BIOS to my email: [email protected].
My PM don't work...I don't now why...
thanks -
You need at least 5 posts to use the PM system.
-
ok, thanks. Good to now
-
I've mailed it to you.
-
thanks Blacky, the Bios works greate for me
-
it is possible to reduce the voltage in 2D mode (and 3d) to below 0.8?
I can only hit 0.8 and higer Voltages -
hi,
Could I also get the Bios for 280m GTX mxm 3.0
OC by Blacky??
[email protected]
Edit: Clevo W860Cu -
I only have the BIOS of the 280M and the 285M from the D900F (MXM 3.0). I am pretty sure that the vBIOS will work with a card from a W860CU but it's your call.
GTX 280m Bios (MXM 3.0b)
