Rivatuner and Gefoce 7800 GO

[Seppi2k]

I've recently bought a Dell Inspiron 9400 with a Gefoce 7800 Go.

after installing rivatuner i have this shown in rivatuner:

That seems to me that there are 2 pixel and 2 vertex units deactivated.

Is there any way to activate them?

PS: Here are some other informations about my GPU:

Mmmm, so the go 7800 vinilla is 16 pipes/6vert shaders.. The go 7800 gtx is 24 pipes/8vert shaders. Mmm, if you could try and unlock some of those, but i'm not an expert on this kinda thing :)

[Guest p.schanz@comcast.net]

:)

I really wish someone with the goods on this post would respond,

I just got a e1705 with the nvidia go 7800 and feel like this puppy should be moving a little faster ?

I didn't keep the rivatuner installed cause I didn't see/know what I could really do with it to rev this rig up ?

I just went with the 83.20v2 and coolbits to bump the clock but I know someone wiser then me could make more of this set-up....

anyone who knows there stuff please contribute...

I cant really contribute much as i am a noob...but I would love two learn more here so I will be hanging around and listening -

$0100000001 Hardwired ID : 0090 (ROM strapped to 0098)

a desktop 7800 GTX bootstrapped to Go 7800. DDR3 wohoo!

PowerMizer will then offer 2 states:

$1100010001 Performance level 1 : 100MHz/329MHz/1.10V/100%

$1100010002 Performance level 2 : 250MHz/329MHz/1.10V/100%

I quote Miki for the suggested procedure:

RivaTuner reports that there are no masked pixel/vertex shader units on my NV41 Go 6800. So it comes down to this:

1) mobile NV41 (and possibly NV42) chips do not have unlockable units

2) locked pixel and vertex units are hardware masked which means unlocking them will require flashing a GeForce with a BIOS from a mobile 16-pipe GF6800 chip (which does not exist at the moment)

Unlocking a mobile chip is not possible atm but I would like someone to prove me wrong...

Means (in this case the otherway around) someone who dares to flash a Desktop VBIOS to a mobile one (and considers to flash the GPU worthless :) ) could have success. PowerMizer features will probably be gone, but that's probably OK for the one who needs the thrill :)

[Miki]

Yes , that is correct for NV41 / NV42 chips but his NV47 has software masked units which means they can be seen and hopefully unlocked with RivaTuner. You can see the RivaTuner screenshot from my 6800go in attachment - there is nothing to unlock :) .

nvaio.cmd

Seppi2k you should be able to unlock disabled pixel/vertex units by putting a checkmark next to them and restarting the computer when RivaTuner asks you to. But BE CAREFUL !!! Theoreticaly you can damage the card by doing so but chances for that are minimal. You should unlock the units one at the time, reboot, test them in your favorite benchmark/game for a solid hour to make sure they are not corrupted. If you see errors in rendering like random noise or badly drawn polygons disable that unit and try the other ones. Remember that you are doing this on your own responsibility...but you can speed your games 50% if you succeed :)

[Guest Guest]

So has anyone tried checkig these disabled pixel/vertex units ?

I will wet myself if I can actually get away with opening up more pipes.

That's what i tried to describe :)

Hopefully it will work. For the brave one :)

So last night I tried to unlock both the pixel pipes that were dissabled and the vertex ones.

After I did this ones at a time both made my benchmarks go way down ?

It seemed like unlocking them became liking towing a trailer ?

So I locked them back up and im back to where I was

Of note was when I unlocked them and ran under coolbits utility overclocking it suggested my core go to 390 and my memory to 990....got really excited there but like I said when I got to benchmarking it tanked....and thus I locked them back up.

If I did something wrong ? I don't know, but I think I don't know enough to comfortably paly with this ?

I can't afford to fry this card the first week I have it ?

Maybe your 7800 is doing the thermal throttling because you overclocked too far.

In control panel check 'No overclocking' in Clock frequency settings panel.

Did you reboot after unlocking the pipes ?

Try to unlock one pixel quad , reboot and start RivaTuner again. You should see something like 'NV47 (A1 20x1,6vp) with 256mb ddr'. Run 3DMark and see if there is any difference. If there is... :)

I've already tried these steps but the units aren't unlocked after a restart... :P

Any other idea?

I don't know enough about this to offer any good suggestions, but since i have an e1705 on order with the go 7800 i am just letting you know there is plenty of support for this concept if you can get it to work. I am sure there will be lots of people ordering these and realizing the huge difference between the go and gtx. On the same note it would also be useful if someone could verify if it is or isnt possible to somehow get a gtx card installed on a 9400/e1705. I would imagine it may disable the dual core if it is possible since the xps doesnt have dual core and you would need to flash with its bios. I dont known if the card slot is identical or not. Also I noticed you need an xps power supply to get the 7800 gtx installed on the 9300, I didn't get my e1705 yet, but is it possible that your opening up those pipes is taking too much power away from the rest of the computer to allow for good benchmarks?

As far as iam concerned go7800 in dell 9400 has lower voltage than go gtx etc.

that's the only reason why it cannot work on the same freq..

so even if u could unlock the pipes u'd need more power .. so overcklocking possibilities

would fall down and u'd end up with unlocked pipes and similiar 3d power as now with overcklocked without that pipes..

but i may be wrong:P

anyway i have 3380 on 3dmark 06 which is ok for me (370/943) temps still ok

cheers

[Guest stenneth]

Anyone seen this thread?

http://www.notebookforums.com/showthread.php?t=136668

- looks like the voltage CAN be increased on the 7800go. Maybe doing this would allow the extra pipes to be unlocked successfully...

[Guest Guest]

didnt anybody notice that after u unlock thoes pipes and reboot, it still says dissabled when u go back and look..............

am about to up the voltage soon :) put the complete cover to work :)

[Guest Guest]

i would be really interested in anyone that has been successful in overclocking the 7800 Go. There is hardly any talk of this on the internet. If it's the same chip then maybe you can load it with the 7800 gtx bios?

[sniperfox]

I'm sorry to bring this old topic out into the light, but i kinda wanna add/ help out.

To the last poster, i've been overclocking my 7800 go almost ever since i got it. up to about 375-380. temperature is still pretty nice too, usually only going up to about 45 when playing games (i do have a cooling pad on the way, too)

The main reason i have posted, is (believe it or not), i believe i have managed to unlock the pipes (the ones previously shown at the beginning of the topic). I bad thing is, i simply used rivatuner, which most of you have, however it worked for me. so what we gotta do is simply find out why its working for me, and not others.

btw, roughly, my specs are:

i9400

core duo 1.86 ghz

geforce 7800 go

Now, what i've done is basically used rivatuner, put a checkmark next to the 4 pipes that were disabled, clicked apply, clicked ok, then i was prompted to restart my laptop. When it booted back up, i turned back on rivatuner to see if it had dissapeared (i had expected it to, due to the previous posts). and to my surprise it had not.. the pipes were all enabled.

So, i decided to test this sucker out :) i loaded up S.T.A.L.K.E.R, and Battlefield 2, and noticed signifficant improvements

as in.. i can run battlefield on the absolute highest graphical settings (full resolution, full AA/draw distance) with near perfect framerate (perfect being in the 30's, as im told that the human eye cant see any higher).

Please, i wanna help. so if there's anything i can do to.. prove, or show how i did it, i'd be glad to help. Maybe it would be a good idea to overclock your gpu at the same time? i use rivatuner to bring that up to about 375
