Have a 7900gtx flashed and moded the bios to reflect k-pops recommendations temps running 10F lower at idle and even at full load they have dropped about 10-20f. I was also able to bump up the memory to 738 and core to 560. Overall the temp for the entire laptop are lower due to this

Option is to use Mr K-pops rom and keep the Voltage low for 3D.

I agree with Mr K-pop. Lowering Voltage does Work

Currently running

VID 3 = 0.9 V
VID 7 = 1.0 V
VID 4 = 1.1 V

Well i have chosen 2D-->0.95V, 80/80Mhz
3Dlow--> 1V, 200/300Mhz
3Dhigh--> 1.05V, currently 525/650Mhz but still testing and a max temp. of 87°C

It works well and was imho nearly far too easy to be true. But why nvidia or Dell havent done this themselves to change the voltage in dependence of the clocks if it is so easy ?

It is very complicated for my to explain things in English because my language is the Spanish. Sorry..

Dell's graphical cards have 2 models of memory:

- K4J52324QC-BD14 (gtx), 700 Mhz maximum frequency (1400 Mhz effective)
- K4J55323QG-BD14 (gs) , 700 Mhz maximum frequency (1400 Mhz effective)

The only difference between they is the quantity of memory. There are many graphical cards for pc that have the same model of memory.

http://www.samsung.com/Products/Semi...ily_cd=GME1001



The dell bios of 7900 gs and gtx have in Timengset7 the ideal values but they are not loaded in the records of the gpu. If you want to verify this, do this with nibitor:

Tools -> Read BIOS -> Select Device -> OK
Tools -> Read BIOS -> Select Device -> Read into NiBiTor
Timings -> OK -> Test timings -> GetTimings

For example if you have 7900 gs (with original bios) you obtain this:



And if you have 7900 gs (with bios “memory optimized”) you obtain this:



The ideal values according to the manufacturer…

Advantages of having the ideal values:

- The graphic card allows major oc.
- The temperature in idle is minor.
- Longer useful life.

Another thing…

The two graphic cards are the same.. The two have the same bios, the same number of transistors...

7900Gs
7900Gtx

The only differences are:

- Gs has disabled 1 vertex and 4 pixel pipes.
- Gs has a aluminium heat sink instead of double copper heat sink.
- Quantity of memory 256 instead of 512.

It is important to know that the gtx and gs only have 2 voltages availables 1v and 1,24!!! Try this bios and comment..

Bios with very low voltage for 7900gs



Certainly, I am going to comment the problem that I have corrected in the third version of the iso…
In the mode “Maximum power savings” on battery you obtain with atitools over 40 fps with a gs (original bios), due to the bug, only it was obtaining over 4 fps. With the bug it is impossible to see a simple movie running with battery.
I expect to have clarified something. Bye..

You change the GS bios timmimgs with a GTX bios timmings, but still you dont get the same MAx memory clocks with a GS bios as with a GTX bios. There is a differnece between Theory and law, and that is the facts to support it. there is no MAX or AVg fps comparison, no stability test (the most important part i think) and ofcourse the fact that you wont overclock a much as with the gtx, why? i dont know...

My testing shows the same, but K-POP says different so i might be wrong... i am not sure its hard o test power cunsumption under nonbattery use.

So i got you worng, sorry. But then again, changing the vids makes the drivers use different voltages so a good combination (something lacking here) would allow the driver to select the right label and set it under battery use, with me, cuz of my drivers, thats not happening, and with some others is the same. So my general point is the bugs, i can correct them but what i cant do is apply the unlocking featurre to my videocard without having to use these roms. we are an open community so plz again, i ask you to post the unlocking information so we can create our own rooms and customize our videao cards without having to evade these bugs.... the work itself diserves a lot of recognition and i was just wondering if it was luck or not, sorry if that offened you, all i want to know is how to do unlock my card using my own bios... is that too much to ask?

I am not going to argue over the voltage issue really. Its really up to each individual person as to what they decide to do. Really though, considering I have a drop of 12C at a full load just by changing 1.24V down to 1.05V tells me I am right. Voltage = Heat in this equation. Also, When the core is set to 600Mhz on my card, and I change the voltage to 1V I cannot run ANY 3D applications. They just crash... but I suppose the voltage has nothing to do with that right? I guess the only other point to make would be... why on earth would there even be an option to edit the video cards voltage table in Nibitor, if it doesn't do anything? I guess somebody should go kick the creator in the gonads ...

Like I said. I won't argue it. I have seen other people try it and report similar results to mine. I have mentioned the voltage mod in every 'BIOS Hacking' post that has sprung up on here, so I know I got my word out. With that being said, I am not quite sure what 'bug' has been worked out of the new roms, but what I can tell you is that my 3D clockspeed REFUSES to step down when I unplug the computer or shut the lid. So I effectively get 600/800 clocks while on battery. In other words I get like 45 minutes of battery life lol... I won't say that it's the BIOS mod just yet because I am running Windows Vista Ultimate and so far I cannot get Rivatuner or ATITool to work properly, so I will have to wait to figure out what is really going on.

interesting discussions here

my 2 cents, powermizer works on his modded 7800gtx file (non memory "optomized/farked about with" depending upon your point of view) lol

I'll try and do some benchmarks at the weekend when I have more time

It sounds like a powermizer flaw that the card goes to max performance mode when you run on battery.

Does the card downclock normally from 3D to 2D when U are on power cord?

Disabeling powermizer (new controlpanel) will make the card run at 3D mode all the time.

Its currently stuck on 3D ALL the time... pretty sure its the driver though. I don't have many driver options yet, since I am on Vista.

That has to be beacause of your vista drivers because mine is currently running in 2D-Mode and it switches quite normal.
Currently I´m stucked at 565/750 due to limitations of the Rivatuner.

Quite sad that for me in Germany it is even harder to get my fingers on a dual-heatpipe than you who have Dell spare parts, but they won`t sell to oversea people.

"...You must note that the voltage label is not responsible for the output voltage, it is only used by the driver to select correct VID..." (the creator) See here If you do not see the truth, it is because you do not want..

Which is then yolda, you are from A or from B? If this bios works well in my notebook. Try it and later to comment on myself if it works or not. It is simple. Another thing The first iso had a bug thanks to me, in the second version it has been corrected, that is all. For example if you use the bios 790GSUNN.ROM of the first version you obtain: Original 7900Gs bios + Frequencies unlocked + Side effects runing in battery (thanks to me). If you use the bios 790GSUNN.ROM of the second version or above you obtain: Original 7900Gs bios + Frequencies unlocked. I have not modified anything that it has to see with the performance of the graphic card in battery!!!! Only the unlocked.. If you use the 790GSUNN.ROM (second version or above) bios you obtain the same result that with the original bios.. Yolda if you want to know is how to do unlock your card using your own bios compares the 790GSNNN.ROM (or your original bios) with the 790GSUNN.ROM bios and you can find the unique difference that exists between them. Or uses the 790GSUNN.ROM bios and modifies this one to your taste. More information that does not seem to be clear.. Phrases like.. "my 3D clockspeed refuses to step down with the original bios..." are not completely correct. VID0, VID1, VID2, VID3 = 1V VID4, VID5, VID6, VID7 = 1,24V This is for 7900gs and 7900gtx. The 7950gtx has a new regulator of voltage with three voltages available. Why? 3 2 1 (bit) -------- 0 0 0 -> VID0 0 0 1 -> VID1 0 1 0 -> VID2 0 1 1 -> VID3 1 0 0 -> VID4 1 0 1 -> VID5 1 1 0 -> VID6 1 1 1 -> VID7 X The third bit (X) is the one that changes the voltage of the regulator of voltage. The second bit and the first one do not do anything. With the original bios and changing the vid of 3D clockspeed I obtain: (cube of atitools) -Vid0 ->74º -Vid1 ->74º -Vid2 ->74º -Vid3 ->74º -Vid4 ->80º -Vid5 ->80º -Vid6 ->80º -Vid7 ->80º Rivatuner shows the following thing in a Gs or Gtx: CLOSE LID MASK = 011 OPEN LID MASK = 111 Closed lid: [CLOSE LID MASK] AND [0, bit1 2D VID, bit0 2D VID] = [VID that show Rivatuner]. 011 -> CLOSE LID MASK 011 -> 2D VID (Vid3 In our case) ----- 011 -> Vid3 (gs and gtx) Opened lid + idle: [OPEN LID MASK] AND [1, bit1 2D VID, bit0 2D VID] = [VID that show Rivatuner]. 111 -> OPEN LID MASK 111 -> 2D VID (Vid3 In our case) ----- 111 -> Vid7 (gs and gtx) Opened lid + load: [OPEN LID MASK] AND [1, bit1 3D VID, bit0 3D VID] = [VID that show Rivatuner]. 111 -> OPEN LID MASK 111 -> 3D VID (Vid3 In our case) ----- 111 -> Vid7 (gs) 111 -> Voltaje alto 111 -> 3D VID (Vid7 In our case) ----- 111 -> Vid7 (gtx) For this motive there are people who thinks that the graphics card always is in 3D but is not true. If you want to verify it, try this bios in your gs. The unique difference with the original are the chosen vids. 2D and THRTL --> VID1 (1v) 3D ----------------> VID7 (1,24v) Rivatuner shows: Closed lid 011 001 ----- 001 -> Vid1 Opened lid + idle 111 101 ----- 101 -> Vid 5 Opened lid + load 111 111 ----- 111 -> Vid 7 I demonstrate the things with facts. Others only with words...

Powermizer work like always but now you can select the mode "Maximum performance" runing on battery.

If you want to preserve the card of high temperatures, you should use the 790GSUON.ROM. Then fits the frequency of the core and the memory from atitools or coolbits. Max. frec. are 450/800 (1600 effectives) approx. with this bios.

The only thing you have to do is use the hacked BIOS of your choice off of Juan's ISO, and follow the below image to make the changes I have made. You can feel free to try any voltages you desire, but these are the ones I am comfortable with. Once you do the above, you can save the file to your computer, then add it to Juan's ISO and reburn it. If you are going to be flashing a 7900GS with the GTX BIOS you will need the -4 -5 -6 flags added to the NVFlash command. Example would be NVFlash.exe -4 -5 -6 xxxxxx.rom
OK... with all this craziness being flung about, I tried to make the most sense of it, and went ahead with this: I used the 790GTX.rom bios provided by Juan, opened it in NBitor, and then changed the voltage tables to what Krazy has in the above post/image. So far so good You guys are great! I am idling at around 59C and everything seems stable. I let the NVidia Control Panel find the Optimal setting, and it has landed on 550 Core/700 Memory, which is where I will keep it until I wanna play Oblivion or something ha. Before I altered the voltages, I had clocked the card to 600 Core / 800 Memory, and it ran without artifacting in ATi Tool. I was running a little hot, at about 91C, but that is to be expected? Are Krayziepop's settings ok to use in the 790GTX.rom??? Also, the slider in the NVIdia control panel stops at 800 Memory. Is this normal? Edit: In addition, before these new "unlocked" BIOS were released, I was getting artifacts at 600/800, but now I am running perfectly stable. Whats the difference between the old one from Yolda's roms and the new one provided by Juan?
