Acer 8935g does not detect replacement ATI 6770M graphics card.

Hi,

I bought a ATI 6770M from ebay and installed myself to replace the working ATI 4670M to gain better performance. I installed it myself and when I booted it just gives me 3 beeps, 1 long and 2 short beeps. I don't know what I can do to fix it. It does not allow me to enter in BIOS or any screen. I tried to contact ebay seller from Hong-Kong and had no reply from them. Not sure what I can do. It might the Acer Bios does not detect the card. I have the latest official bios. Has anyone got a which will recognise the 6770M????

Now I am back with the ATI 4670M and I am stuck with 6770M and don't know what to do.

Anybody please suggest what I can do to fix the 6770M and up running.

Thanks in advance. Please reply soon.

 

Dude You have probably that same problem what "valuxin" from this thread: http://forum.notebookreview.com/acer/708527-amd-m5950-hp-acer-7738g.html. Those beeps means that bios is searching for option ROM, but can't find it.This option ROM is probably video bios. What kind of card exactly You have? Make a photo and show us.

 

Hi,
Did You solve Your problem?
I just bought ATI HD6770m on ebay for my Acer 7738g and it is the same story. When ATI is in.. 3 beeps. When I put back old GT240m - than all fine... does anyone have and idea... or suggestion.... (except giving up).
Thanks
Tomas

 

Which ATI HD6770m is it? Because there are few different ones. What color of pcb it has? Can You make a photo of it and post it here?!

 

got the same prob with an 7738g, pcb of card is blue, no vbios. any way to get this working?

 

Solder on a bios chip with the right file on it.

 

Blue PCB - only for MAC as with black PCB.

To author - probably you have ROMless version. There are two ways to solve the problem:
1. Solder BIOS chip on it and than use blin-flash method.
2. Integrate vBIOS of HD6770M in sBIOS of your notebook.

 

Does anyone have anyhting new on this subject? I have 2 6770m's now, trying to upgrade my aspire 8935g, and it was sooo close, i integrated the one available vbios into my sbios and when i inserted the first card, everything booted, i installed drivers, benchmarked it and played a game. Despite some spikes and graphics bugs i was happy... well, these bugs mean faulty ram (tested with vmt).... cant play fore more than an hour or so.

So i ordered a new card, this one doesnt work at all, black screen (not even light). Both are green, look the same, but one is very close to working, the other one does nothing.

Ideas anyone?

P.S.: The main problem with romless cards is, if you are not lucky enough to get the exactly right 6770m (the dell-Version) - for this card there is a bios available on techpowerup.com, integrating it into the system bios is quite easy - it simply wont work. Believe me, i put a lot of money and effort into this.
Final solition: buy on aliexpress.com for about 180 USD a card with rom (red pcb, the description lists only the 8735g, but 8935g definitly works). If anyone should ever be looking here

 

Hi Frxxl,

Could you please explain more on the card from aliexpress. del M17x M15X .ACER5935,5739,5940,8735,HP8540WP HD6770M 1GB DDR5 MXM3 graphics card-in Graphics Cards from Electronics on Aliexpress.com

Did you actually buy and installed it yourself?? Did you had to install bios rom or anything or did it come along with it installed so you could directly install in acer 8935g. Please reply with details so I can go ahead and buy one of these.

How is gaming improvement after with the new card.

Hear from you soon.

 

The card you linked already has a bios chip you need to just plug it and ready to go.
The romless cards are blue and green ones.

 

Success!!!!!!!!!!!

The card with red PCB worked perfectly and detected with no problems.

Any comments or help needed let me now.

 

Hi, sorry for not replying sooner, this forum should really have the option to send an email if anyone directly replies to a quote... Well, congrats to your new card and a faster notebook . I just finished my upgrade marathon with a T9900 which finally brought me to 10.008 points (i really wanted 5 digits in 3dmark06. Part of this run was a western digital black series 750gb, a panasonic 260 bluray writer, 8 gb ram and of course the card i wrote about. All combined really cheap for a stylish and fast 18-inch-full-hd-notebook.

 

Hi Can I ask if this was a fairly simple process- apart from dismantling the laptop bit obviously!
how easy is it to combine the bios ?? that's the bit that sounds scary?
I've always had a graphics card problem with my 8935g - when on the HD 4670m it just randomly locks up with random colour screen crashes.
tried changing voltages and clock speeds trick but still crashing- just unsure if spending £100 will fix it and don't want to kill my laptop.
regards
Graham

 

Hello!

If you`ll buy 6770M with RED PCB than no BIOS integration will be needed. Just mount it in the laptop, install drivers and you are ready to go. If you`ll buy 6770M with GREEN PCB, only than you`ll need vBIOS integration in sBIOS. Thus, just buy 6770M with RED PCB.

 

Hi thanks for the reply
I just bought this one
ATI HD 6770M HD6770M Whistler-XT DDR5 1GB MXM A 3.0 Video VGA Card Module | eBay
seems right and its red!
hopefully when it arrives you'll see me back on here before I attempt dismantling - just to double check any other things I should prepare first.
Thanks
Graham

 

Okay! Feel free to ask for advise.

 

Please write if it works
I own a 8735 now running a ati 4650 (gt 240m previously)
Looking for a directx 11 card also intrested in the 6770m
Also record temp its working
For example my gt240m never recorded above 60C in full load and additional fan idling at 40c
I dont know about the ati it doesnt have a sensor on it (never stressed it that much)

 

Hello guys,

I'm happy to see more ppl trying to upgrade - havent been "screwing" around with my perfected 8935g for months now, it still works fine and fast and relatively cool (max. 70° C).

Except a slight glitch i wanted to inform you about: Sometimes after gaming, esspecially from steam-games, the whole desktop is moved about 10cm to the left and enters the screen on the right side again. Don't know what that is and since no1 else on google (=in the world seems to have that problem, I did not find a final solution to prevent it. But, in case some1 else has it (and if not here among the 8935g-upgraders, where else), fixing it is fairly simple: Press Windows+P (or do it via output-options as if you had an external screen or projector plugged in) - windows will search for other devices and re-initialise the main screen as well - and when it finds nothing, it goes back to the normal screen (maybe press win+p again), in my case always in the right "order".

About the (dis)assembly-questions: I found, via google, the official disassembly guide, a pdf of about 10mb (or more, not sure atm), with step-by-step descriptions and pictures for every step of the process. I didnt need it any more after 3 or 4 times and the next notebooks of friends leaning on my experience i opened without any guide... But to start with it helped me a lot. Of course you need a tablet or another pc to open the guide while you work ... or you can print those about 200 pages, but it think that would be a waste.
To answer the question directly: The process is, in my opinion, a simple one. I was scared to damage stuff at first, but all combined I took the notebook apart completely about 8-9 times, flashed the bios about 20 times, half of them blind because I had no screen signal from the installed card... Of course you have to work "carefully", but if you don't use brutal force (if you have to, u forgot a screw), that stuff is quite solid.
Oh, and another useful hint: When u plug the cables back in - leave out that stupid touchbar on the left. I was so annoyed about switching of my wifi accidently when gaming - not any more , and no, i had no problems at all without this thing.

Anyway, congrats to all red-buyers, esspecially now that i see the card costs only half of what I payed only a few months ago - have fun with you upgraded machines

 

Card is winging its way via drift wood from Hong Kong as I type ! lol
Already found the service manual and have it on pad ready fingers crossed it goes well.

 

It looks like you're well prepared , I wish you all the best, meaning everything works from the start which it should.

Still let me, if you care to, give you some "advice" to speed up your way to happiness - maybe you thought of some of this already:

1) Update your Bios to the latest version 3212 before you start anything else. There is an unlocked version available ( http://forum.notebookreview.com/acer/480992-acer-laptop-phoenix-bios-bios-mod-request-47.html ), I'm using it, works great - you dont have to, but 3212 from official acer it should be.
When your're there already: Really, when you open up your laptop, think about a new cpu. The T9900 works fine and if you have a core 2 duo atm, you can keep using your fan-module - for a quad-core which I am thinking about since i started reading here again today you will need another cooling-unit. Other cpu's are, esspecially in US an China, cheaply available thx to a weak us-dollar - really, think about it.

2) When disassembling, have ready:
-Enough space to work and to store the components in some order. I used a large cotton-towel to cover the kitchen table to avoid scratches and stuff.
-3 Boxes to store the 3 different types of screws (all of the cross-screws?-something...what is it called?).
-New thermal paste ( I use arctic mx2, 4-5 euros @amazon) - and I found it useful to have some removing liquid as well. Again from arctic comes some really good stuff ( http://www.amazon.de/Arctic-Silver-...qid=1405449462&sr=8-1&keywords=arctic+remover ).... Anyway of course you need tissues and q-tips for the old paste.

3) You need "special" drivers - windows (8 in my case) provides some, but of course you would want something at least close to new... I got mine from here ( AMD Radeon HD 6770M: Aktuelle Grafiktreiber verwenden | MTRV )

Allright, so much I could think of spontaniously - I hope you get things done faster than I did

 

Thanks
Already updated Bios along time back to see if that fixed my MCSOD's (multi coloured!) What is different with the unlocked Bios?
I'm lucky enough CPU wise - I already have the core 2 quad Q9000 - pretty darn fast still I feel so extra cooling for me - looked at the next step up but to be fair I would rather spend the money on some extra ram?

Got my thermal paste ready MX-4 , was nothing between the prices really about £4 free postage! and my wifes nail polish remover- acetone its all about the cost for me lol
Its just the drivers that I'm wondering over - I run windows 7 so was just going to put my details into a(any) site and see which catalyst they recommend ?
gonna download 13.4 from your link just so I have a set ready to go - did wonder about the leshcat drivers - although they didn't work well with the current 4670m - didn't set the resolutions up and only gave 4:3 options not 16:9
Anyway -hopefully not to long to find out if I kill my laptop or not !!lol

 

For cleaning old thermal paste and pads, you should use alcohol instead of acetone. Acetone can destroy plastic components and some SMD parts.

 

Mmm not impressed, ordered a red card and they've sent a green one AAARRGGHH! 3 weeks wasted and probably have to return it before they send a replacement.... If they have one! Only problem is that I got to excited and dismantled before I realised

 

Sad to hear about that. =/ Before sending it back you should try to modify your BIOS by integration vBIOS in it. Ask valuxin for help.

 

Does anyone have a comparison of the different cards- apparently the v bios chip is missing on the green card- but I cant see a difference to my green one and the red card?
comparing it to the one on the aliexpress site (posted earlier here) it looks the same?? or is it just missing the codeing?
Im not sure I want to play with rewriting my bios! sounds complicated -I would rather plug and play- unless it really is a simple ... very simple fix! lol

 

If you want to try (u did have the 8935g just to be sure?) a modded bios before sending it back (I did that really often and do not recommend it, get the right card...) - if you want to try, I can give you the unlocked version 3212, vbios from techpowerup is built in already. But the chances are not good, I tried romless 3 cards (and there is no way to know if you got an hp card, from Dell or Apple or whatever) and only 1 worked with that bios... But the ram was faulty... Yes, it was a long journey ;-)...
Ok, back to the point, if you have the right notebook and want to try, I have the file you need ready. If you tell me how to get it to you, I will send it.

 

well ive just compared mine to a romless chip version and mine does indeed have a bios chip on it!
would it be worth trying or is it likely to have the wrong bios in it?
not sure if I can dismantle to just try it in case!
they state it is ATI,ACER ,DELL bios

and yes I do indeed have 8935g

 

Post an images of your card - front and rear sides. I don`t remember, but if I`m not mistaken, I so only once a GREEN 6770M with ROM chip. And if I`m not mistaken, that it appeared a 7770M, not 6770M. User, that bought his *6770M* thought that it was 6770M. After installation - the card was recognized as 7770M. But he had no problems with that - just plug-n-play. All 6770M with ROM chip have DELL or HP BIOSes, that are compatible with our laptops. GREEN and RED 6770M have different components - VRAM, condensers and so on. Maybe you`ve received not 6770M? If you post some images, I`ll be able to tell more about your card.

 

Alright, that sounds strange, I never heard of a non-red card with a bios chip on it (I've seen blue, red and green - and heard that theres black as well).... But why shouldnt there be.

So, to make it quick, if the card has it's own vbios, you dont need to fiddle with your notebook-system-bios. It's just plug and play then. I find it very, very unlikely that the card has a wrong bios on it. You can of course flash the vbios on the card (tried that with the romless versions, that's how I found out there are romless versions ;-).... But since you have no way to know what card you have, you have a much better chance to brick it than anything else. So again: If the card has it's own bios, it does work instantly - or it wont at all.

If you have a romless one, it's more interesting (maybe you know some of the stuff following, but it wont hurt to repeat it). In that case u need to integrate the vbios as an option rom into you notebook's system bios. It's a lot simpler than it sounds, there is an editor available online. You take the original (or the modded) bios from acer, grab the vbios from techpowerup, use the editor to simply put it in (there is actually kind of a slot/folder for it - for many option roms, with those u can make some stuff in your notebook work, like onboard graphics, network etc.).... Compile it and ready.
The big BUT: There is only 1 Dell-Bios online at techpowerup (I extracted another from an hp-Bios i downloaded, if you want, you can try that as well) - but from my experience you just hit the right combination of card and vbios. It's also not possible to simply put in some vbioses - the system doesnt know the right one and will always use the forst vbios for the card currently plugged in - and if this bios isn't the right one, your screens stays black and you have to blind flash the bios in order to get visual again from the onboard-graphics (which actually is a nice fallback, otherwise you had almost no chance to get the screen back on without taking everything apart again and plugging in the old card).

Man, once into it I can's stop myself from typing, sorry it gets so much every time. I hope i can save you from wasting so much time as i did on trying to make romless cards work to save a few bucks. It's not dangerous in any way, you will always get back to a working system, bios modding and flashing really becomes childs play after the 10th time or so ... but it simply doesnt get you anywhere besides less sexual intercourse because your wife is annoyed by you working on this every evening.

Put in the card you have, if it doesnt work, order the red one, be happy .

sorry it wouldn't let me upload to the forum- ive added links to my dropbox if that's ok-
as you can see top pic -top right of card is tiny black chip then slightly down and left is bios chip!
also added a close up of the gpu so numbers can be seen

 

Interesting. The GPU chip is really for 6770M. And what`s not less interesting - it is not ROMless. Does the X-bracket was delivered with card and was it fitted by default? Hmmm, it is like HP version of 6770M due to X-bracket. If it is HP - it has to work. On your place I would send it back and ask for refund or 6770M with RED PCB.

Or, you can do a blind-flash of the card using BIOS from techpowerup. If this card is not dead, than after that it should work. If it is dead or, by some reasons, it is not 6770M - the card can be destroyed. And maybe not.

And yeah, it can be *M5950 FirePro*. Even if so - it has to work as it should. And even if it is M5950 and has BIOS from 6770M - it should work too. P.S. there is a trick, when people take professional cards, that are made on the basis of gaming cards, and flash them with BIOS from gaming version of the card to *unlock* gaming capabilities. But again, I`ve never seen M5950 with GREEN PCB - only blue and red.

Buy this one and forget about the problems.

 

I was thinking about giving it a try but have also just noticed that the gpu chip is set diamond on my original and square on the new green card - Just wondered if that's gonna be an issue with the cooling coz I'm sure the copper cooling plate on the fan is set diamond as well.

 

So OK I gave a try. getting al the way to fitting the board -fine.
but the heatsink will not fit back onto the card as it has a 4 legged support bracket on it with captive nuts and the thread is too small for the screws to pass through.
Warning for others to be aware of - unless you are brave enough to remove the bracket! but it seems to be bonded to the card.(or drill out the holes!!!)
All was looking good up till then

So ive contacted them for a return or replacement.
watch this space lol.... in a few weeks- please allow time for the pigeon to fly back to hongkong!

 

Pay 10 - 15 bucks extra and get it faster, worked for me, from China to Germany and into my hands in 4 days. Ask the seller if he can do that

 

I`ve told many times about this X-bracket in 5739G and 8940G threads. It is glued on the PCB. You can heat it with heat gun and than carefully remove it. When my M4000 arrived, it had X-bracket too. It was removed by heating and one of wife`s kitchen knifes .

 

So do you think its worth while trying this card if I remove the x bracket?
im getting quite good at the taking apart bit now! maybe 3rd time lucky
otherwise its gonna cost me £8.99 to send it back to hong kong , looks like the seller wont pay for the return postage even though they sent the wrong card

 

Remember - if you remove X-bracket, than the warranty on the card will be cancelled. So think twice - or you continue to dance with that card and try to -remove x-bracket-install-mod-flash-boot it, or you send it back, ask for money return or for RED 6770M.

 

would it definitely need flashing to work- would not have a clue how to do that
I was hoping that it would be plug and play-looking closer, the x bracket is really not stuck on well at all! it will fall off if im not careful

 

Your laptop can boot even if cards screws are not screwed in, if the card is just plugged in the MXM slot. If your laptop turns on after power button hit and you see a black screen without windows sound starting, than the card probably need to be flashed via blind-flash method using USB-drive. If the laptop will boot and you`ll see post on the screen and windows is booted - than you can remove X-bracket, install the card as intended and start to use it.

 

Well I'll have to give that a go then, they did ask me if I'd tried it, so even if it doesn't power up then I can still return it.

 

Yep, that`s right.

 

Major update now then!
After a week or so of messages backwards and forwards from the seller - we come to a partial refund agreement-
I intended to test the card anyway so that just set it in stone - I could take a £40 loss if it didn't work
so with a little pressure from a finger nail the x bracket popped right off! lol
card went in ( 3rd dismantle lucky!) and hit the power button.....
WINDOWS! picked up the card right away and started installing drivers for it.
I had pre downloaded a catalyst package anyway so - I was going to install it but when windows found the card it came up with a different model - so I download the auto device detect from amd site.
that found an m6000 card a HD 6740m to be precise and downloaded the catalyst 14.4 package - which turns out picked up a firepro card!
now everything is working graphic wise-
question though would this be the correct driver for this or should I be forcing it to see a different card ?
its picking it up as an A series APU- this has sort of thrown me -as reading about it -its a workstation card?
the only issue I have found todate is over HDMI I get no sound when plugged into my TV?? it worked before- any suggestions?
lastly I have GPU TEMP running when I have been playing some games and so far its maxed out at 66 degrees!
all in all im pretty happy -so green card with chip works as well

 

I'm not sure that it's what you need, but I remember a part (detailed installation, you could uncheck it) of the catalyst driver was about some hdmi support... Try looking into it, it is most likely a driver issue, the hardware most certainly can do it

 

I have the hdmi driver installed when I did a custom install and that hasn't worked

 

6740M - I have never seen this card as standalone module. Only integrated in motherboard. There is 6740G2 version - but this is integrated too. M6000 - this is FirePro professional card for workstation, and it has MXM III type- B form factor. Your card is MXM III type- A as you know. Try to use GPU-Z and paste results here. I don`t think, that this is M6000 or 6740M. I think you`v bought M5950 or something like that. In addition you can paste here vendor and device ID`s. It`s interesting for me to check these codes in google.

About temps - your temps are very good. In addition you can stress your card in Furmark for 10-15 minutes. Than you`ll see real maximum temps.

 

well here you go- still saying that's its 6700m- device no.6740!
whats amusing is it says ACER is subvendor?? lol -although ive no idea what that means!!

 

Those values strongly remind me of my 6770m... I don't think device ID has anything to do with the model number, on my desktop pc it also only says radeon r9 series. If you want to be sure, open the bios (I think gpu z can do that and if it's a rare one, upload it) and look for the model there - you usually find it far up left, above all the cryptic code

 

Vendor and Device ID`s you can check in device manager, opening Display`s Adapter properties. For me this card reminds 6770M too.

 

so if it is a 6770m and not firepro -which driver should I install- just the straight 6xxx from amd site?

 

Yep, just install 6xxx drivers. And of course you can try to install M5950 drivers too. That`s up to you.
