Acer MXM BIOS Mods and discussion (was: x920G vs. 9600M GT)

[Kailoq]

Reading your original post, I suspect it's not a BIOS issue.

Can you read the serial number off of one of the card's RAM chips?

I reopened the laptop and the serial was [VG.9PG06.009] (= 1GB DDR2), instead of the [VG.9PG06.006] (512MB DDR3) I ordered. I contacted the seller and currently waiting for a reply.

I'm assuming the green lines indicate a faulty chip. Drivers didn't change the appearance at all. I didn't end up updating the BIOS, because I would think an old bios would either recognise the card or give a black screen. I don't want to try updating it and possible screw up my motherboard, when I'll need to try a new card regardless.

hi all sorry i wasn't around for a while
its summer so i was fixing my motorbike
@aikidokaboy
m8 there are 2 solutions to your problem...
no 1:
find a second hand 8600m gt with 512mb ddr2 or a 9500m gs with 512mb ddr2...
those 2 are the same card...you just need to flash the original 8600m gt vbios on the card in order to boot on the internal screen and thats all...
in this case you don't need the sbios mod.

no 2:
you can find a second hand 9600m gt with 512mb ddr3(my is revision A1-from msi)
put the damn card in the laptop and boot on a external display..
first you install the modified sbios from netroler.
next you flash the modified vbios that was confirmed working-find the one from my posts.
next you can boot normaly on the internal screen.
the picture is normal but the problem is that you can't install nvidia drivers...
now just follow my instructions for driver install and you should be fine
i am writing this reply happily form my modded 9920

@u6b36ef
for the cooling i solved it
anyway i solved it my way
i designed a small voltage regulator that i mounted on the side of the laptop...
with 2 settings-normal-load
when the switch is on normal the fan is turning on 60%,when i need xtra cooling i just flip the switch and it turns on 100%...
thats all there is to it...

Has anyone tried or found a way to mod the bios chip on one of these toshiba gpu's? Toshiba N11P 1GB DDR3 Laptop VGA Graphic Card LS-5005P K000092390 | eBay
i have heard these don't have a bios but there is a way to mod it. I've been searching and reading for days to figure this out. I was just about to buy M60J VGA_BD./AS WO/HY_SLI part number: 60-NTSVG1000-A11 When I found out it doesnt have the bios chip either... i am going to put it in my 5720g but i want to be sure its going to work before I waste money on my old laptop.

Please someone let me know if they are found a FAQ or something on modding those toshiba VBIOS on that first card link. or If i am wrong about that asus card and it will drop in without hassel. i want gt240m/gt330m performance. I have heard they are the same chip just higher clocks on the 330m. Please someone let me know!! Thanks very much!

Hi folks,

Been a long time since I last came here. I hope that everyone is well!

Some news about my 9920g : I'm currently really happy with my 9500m gs inside my 9920g, so I sold my 9600m gt to a friend who's currently trying to install it on its own 9920g (using Windows 7).

He followed all the stages that blackened gave in order to make the 9600m gt work on windows, but he is currently blocked at the "purple/double display screen" stage. More precisely, he managed to navigate through this crappy display to find the device manager, found the card on it, and then, he turned a bit lost, because he didn't know which .inf file to choose in the c:/nvidia/... folder.

Provided that he couldn't easily write in english, he asked me to pray for help, in order to achieve this last step before he can fully benefit from the 9600m gt power!

@blackened87 : So, my question-of-the-day is for you, you who masterizes the 9600m gt installation into the "beast" (héhé) bowels! Here it is : Could you give me precisely what is the file he has to choose on the c:/nvidia folder (he told me there are tenth of .inf files, and he doesn't know which one is the good one)? More in particular, would you be kind enough to name the entire exact file path?

It would be really appreciated, and I can already transmit all the thanks on behalf of my friend for all the great work you've already made for improving the 9920g experience (here, I am specially thinking about blackened87, and, of course the 9920g deity, netRolller 3D)!

Many thanks in advance,

Have a nice day, everyone!

Can you please tell me which one is recommended?
8600M GT or 9500M GS?
I mean in terms of overheating which one is better?
And can you also tell me what was the plaster mold made from and which metal compound you used for binding the two heat pipes together?
Thanks a lot mate!

[blackened87]

@hycks:
the path:
C:\NVIDIA\DisplayDriver\296.10\WinVista_Win7\International\Display.Driver
and choose the first inf file...i did not see the diference in them because i think that windows scans them all in the target directory...

@aikidokaboy
well the plaster mold was made out of plaster
and the compound i used was 2 component liquid metal from bison.
you have allot of diferent ones so when you go to buy pls read what are the temperature tolerances and so on...
if you dont have any xperience in this kind of fabrication i recomend that you simply dont do it or you can ruin your cooling system...

Hi blackened,

My thanks to have answered that fast! I will give your answer to my friend, and let's hope that he will finally make it!

One more thing : my friend told me yesterday, that he managed to sometimes obtain a perfect display (using other inf, I suppose), but after a few minuts the computer tends to freeze and reboots.. Is your own 9920g stable, or did it suffer sometimes to sudden freezes and reboots?

Thank you again for your answer, and nice day to everyone!

Damn I can't seem to find any 8600M GT or 9500M GS around.
All I found is a 9600M GS with DDR2...
I don't know what to do, I mean to buy or not to buy it...

[aikidokaboy]

I've decided I'm not buying the 9600M GS...

I reopened the laptop and the serial was [VG.9PG06.009] (= 1GB DDR2), instead of the [VG.9PG06.006] (512MB DDR3) I ordered. I contacted the seller and currently waiting for a reply.

I'm assuming the green lines indicate a faulty chip. Drivers didn't change the appearance at all. I didn't end up updating the BIOS, because I would think an old bios would either recognise the card or give a black screen. I don't want to try updating it and possible screw up my motherboard, when I'll need to try a new card regardless.

I sent the card back, asking for a [VG.9PG06.006].

What I received was a card without any VG-serial. The code on the chip itself was G96-600-C1, which seems to be a 9600M GT, but no one seems to know whether it's a DDR3 or DDR2.

Unfortunately, the card doesn't fit in my 7720G. The heat bracket on the card doesn't have containers/plugs for the heat sink's screws to fit in. It has one of these: , but my 9500M as well as the previous 9600 had little containers where the screws would fit in. This card seems to be designed for a motherboard/heatsink where the screws are inserted directly into the motherboard, instead of having plugs on the bracket/spreader/square thingie.

So I'm back to square 1. How can I figure out what model this laptop was made for? I need to know what to tell the seller so I can trade back this card for one that WILL fit. Or is there a way to attach this card to my heatsink?
