[Help] MSI GX640 issue

I have an issue with my GX640, I bought mxm 3.0b 4870 video card from one user of this forum, it works perfect when i connect the HDMI port, I play Crysis 2 on max. But the notebook screen give me bad colors, and it was ok with previous ati 5850, the colors were ok. There is 2 pictures that explain better my problem.


This is how it looks in my notebook:


This is how it looks in LCD 32' (HDMI port)


I can play, and do everything now, but that is the issue i have.

Please somebody help

 

somebody help? :S

 

Have you tried uninstalling the monitor driver? Removed all ATI drivers? Driver sweeper and reinstall?

 

Hi matizin,

I had a similar problem when I tried flashing a vbios to my 6970m that was not compatible with my laptop. I had the same screen artifacts as you - and windows wasn'y very stable. The display was fine on an external monitor.

I would try the following:

-Reseat the card.
-Reseat the screen cable.
-Boot into safe mode and get rid of everything ATI with driver sweeper.
-Reinstall the ATi drivers. Try official MSI drivers and AMD official drivers.
-Flash the card to a different vbios.

-My guess is that the vbios is not completely compatible with your laptop. I haven't had much experience flashing 4870m's to other 4870m's - I've had a lot of experience with the 6990's and 6970's so I'm assuming they'd work the same.

I don't know if you would run into a problem with the fact that as far as I know all other 4870's made for laptops were MXM 2.1b and not MXM 3.0. I don't know if that will affect the vbios at all.

You can try flashing the 4870m's to the vbios used in the Asus W90, I think Clevo made a few 4870m's, and possibly MSI made some. Track down those vbios's and flash them using atiflash. It's risky so try and see if anyone else has done it first before you.

I'm nearly certain a different vbios would correct the problem.

I'm also curious, why did you swap a 5850m for the 4870?

 

the 5850 was in bad condition, give me black screens, BSOD, didn't install drivers, I never play before because of the 5850, but it let surf webpages and do everything except playing. I've already tryed replacing the card again and didn't give me any solution, I don't know how to flash video cards, so if you can give me any tutorial, I'll be very glad .Also I don't know which is the screen cable :/. How can I reinstall monitor driver? I've never do that before.

 

i dont know how good u are with tech - but i would try linux live cd - to rule out all the software problems...

Ive been using this : Download - SystemRescueCd

Has a graphical ui too - I test things out on live CD so if some problem happens on both windows and linux i can assume thats not a driver issue

 

I ran Backtrack 5 (linux) and happens the same problem, so i think that descart a driver issue?

 

Can it be a bios issue?

 

Probably it is not campatible vga bios with ms-1656. All you can do it is sell vga card and use r5850 or 5870. Also there is a hope with flashing r4850 with msi bios . I should have some bios for 4850 i will try to find, but it is bios for mxmII so no hope .Thirst thing you need to do is uninstal catalyst software suite and install new one (5 min and it will be all clear).

 

i don't think is compatibility issue, this guy make it work a 4870m perfect on MSI GX640:

So try new drivers, but like I said there are several vendors of r4870. MSI didn`t make any r4870 for mxmIII. All you need is take vbios from other vendor if reinstalling drivers fail. It could be also problem with vbios from other vendor - maybe different memory chips . Generally I have been testing on gx640 oryginal msi r5870m vga card and also there were problems with display and I had to flash bios from r5850. After flashing problem dissapeared. But I don`t understend why you bought r4870 instead of r5870m better and faster.

 

What kind of 4870m is he using? Is it a dell card? Is it some other brand? What video bios is he using?

Flashing the card to a MSI 4850m might work since someone said the GX640 supports the 4850m - then just overclock the card back up to 4870m clocks.

You're going to have to hunt down video bios's to try. Unfortunately I don't have any vbios's for the 4870m aside from the original Dell vbios and a pair of vbios's I modded.

I don't know if you will run into a problem flashing a vbios from a MXM 2.1 card to a 3.0 card. You may or may not. If you do run into a problem, you'll probably brick the card though - and your only hope would be a blind flash in the secondary slot of a M17x, M18x, X7200, or X8100.

It is well known that the 4870m can be flashed to the 4850m and vice versa with no problems. Since someone said the 4850m is OEM supported in the GX640, I would try going through that method. Search the internet for a MXM 3.0 4850 MSI vbios.

You can flash it using atiflash.

You'll need to make a bootable USB stick and put atiflash and the vbios in the root.

Boot into the usb from the bios, and run the following command.

"atiflash -f -p 0 insert4850biosnamehere.rom"

That will flash the card to the new vbios. Keep in mind you will run a chance of bricking it, but if you are using a 4850vbios intended for a 4850m that is MXM 3.0b compatible then you shouldn't have a problem.

Using a MXM 2.1b vbios I think is more risky - probably by quite a bit - try and see if anyone else has done it. Contact that guy on youtube and see what he did.

It's possible he had a 4850m in his MSI and flashed it to a 4870m - in which case he isn't technically using a 4870m.

 

As far as I know there is no msi mxm III 4850 vga card . MSI made only 4850 for mxm II.

 

4850 was originally used in the GT725/GT729. But those are different type. MSI newer used the 4870 in any format. So there must be some bios issues with it.

 

I've replaced my 5850m back, and laptop screen was ok again, so it's not screen cable issue,

I've not try any vbios or bios update because it's risky, and i don't want to have my system irreparable , and I've been looking for 4870 vbios and i've found nothing. I don't know what can i do now =/. If someone have any vbios for this card, please upload it, maybe I'll try it.

 

I did notice something good, on this video:

Msi gx640 in hd4870m - YouTube

on minute 0:36 he shows vbios date: 12/17/08

and when i run everest show me that my vbios is 12/18/09:




so i need this vbios and I think everything will be solved, please somebody help me find it

 

Yeah I think you should try to get a variety of Dell vBIOS and flash them all.

 

yes, but i don't know where can i get that =/
