MSI's HD4670 is running in my Acer 5920G

It's been a while, but sadly I wasn't able, nor would I be this week as well, sorry They are just siting on the desk and waiting their time to come. Also I changed my mind, I'll keep one for myself, assuming that both are running correctly.

 

Well, i will check this post every once in a while, to see if it is any progress I will probably buy the nvidia, since it has ddr3 memory + the price is very similar to the hd 4670. If i install it before you do, i will post a comment here.

keep up the good work!

 

Both are working fine, one is pending sale, the other one, as I said, is for me. If anything changes, I'll let you know

 

Hey triturbo,

my GeForce 8600M GT finally died the last day.
Is your 2nd GT 240M still for sale? I would be interested in buying it. How much will it cost?
Do you know if the GT 240Ms have the same heat problems than the 8XXXMs?

Thanks in advance!

 

Sorry, not for sale. The first is already on its way to the States, and I have another plans for the second. You can check in the Acer's MXM thread, on the last pages there's a link to a place from where you can get one, and it's reasonably priced as well. And no, GT 240M doesn't has the issues of 8xxxM.

 

Thank you triturbo.
Did you buy your two cards there:
For ASUS C90 C90S C90P GT 240M MXM VGA Video Card Well Tested | eBay

Do you think they are compatible with the 5920G?

Thanks again!

 

No, different source. There was a bit cheaper one, but not on eBay.

 

I assume you will not tell me your source, do you? ;-)
Seems as if there are 2 types of offers for this card. The hardware revision 2.0, which is stated to be compatible with the 5920G, and HW rev. 1.0 where there is no statement about compatibility.

Of which HW Rev are your cards?

Do they look like the first or the second offer:
Video Card Graphic card NVIDIA N10P GS A2 for ASUS C90 C90S C90P M90GN GT240M laptop notebook-in Graphics Cards from Computer & Networking on Aliexpress.com
Geforce GT 240M N10P GS A2 1GB DDR3 MXM II VGA Card Video card for ASUS C90P CS5110 C90 C90S C90S M90GN Acer Aspire 5520G 5920G-in Graphics Cards from Computer & Networking on Aliexpress.com

Many thanks!

 

What I know is that there are two revisions as you find out. The cheaper one probably features Samsung memory, while the expensive one probably features hynix memory. What this means is - both should work, expensive one should overclock higher.

 

Hey guys,

For those of you who are interested, I want to inform you, that also in my Acer Aspire 5920G a Nvidia GeForce GT 240M is working properly since yesterday.
Though, it gets very hot (>100°C) with the 5920G's standard cooling components when gaming, so I undervolted it to 800mV, 800mV and 850mV for respective P-States P12, P8 and P0 with standard clocks.

Cheers!

 

Do you have copper shim, instead of thermal pad on the core? If not, put one, it would bring a lot of improvement.

 

No, I currently use a 1mm thick fujipoly Sarcon 100 X-m heatpad on the die.
With a heat conductance of 17W/mK it's pretty good even compared to a arctic silver thermal paste.

Of course the thermal paste film is much thinner than the pad, but using a copper plate, there are additional two medium transitions (die -> paste -> copper plate -> paste -> cooling component vs. die -> pad -> cooling component).

Anyway thanks for your hint.
As I already have a copper plate available, if I find some time I may buy some good paste, compare the cooling performance to the single pad solution and post the results here.

 

I'm fairly sure even the with past>copper>past it's gonna do well. I just order fujipoly for mine as well but for the vram. I have contemplated soldering the copper shim to the heatsink. I sure hope itdoens't run that hot because i bought mainly because it's a 25watt GPU versus the 35watt hd4670.

what programs did you use to do that?

 

Hello

I bought an HD 4670 from msi ex623 but my laptop does not cooperate

My spec is 8920g with nvidia 9500m gs
charger 120 w
Need I flash BIOS ? Any idea ?
Could You help me ?

 

Are you sure it was OK in first place? The failure rate of those is quite high, due to the poor cooling design of EX625. Or you mean GX623, it has a bit better cooling, but still, are you sure that it was working?

 

It was from ex623 and working in msi laptop and i in my laptop at the beginning

I installed the card in place of my 9500. I used the standard cooling of Acer . Laptop has launched and detected the card. In Windows7 temperatures were about 55 degrees. CPU 30 -40
In 3dmark laptop turned itself off after about minutes. In cod4 same situation .
I tried Ubuntu also enable the USB drive and the computer still off after 1 minute
When I switch on and stay in BIOS menu my laptop still offfed after 40 second ( ! ) -

It changed my card back in 9500 and works perfectly in win 7 and ubuntu. CPU has a low temperature of 30 -40 degrees

what should I do ?
Regards
sorry for my english

 

I guess the heatsink doesn't sit flush on the core. Remove the whole assembly and take a look how it fits and if there is a notable gap. You may need to do a copper mod.

 

Is the 4670 so hot card ? From start to shut down is just 1 minute or less
.I am not sure is enough time to warm up the card. Sometimes i changed somethings in BIOS and stay in bios menu - it is maximum idle for components but always laptop off
Do You think it is only temperature problem ?

 

Actually when in BIOS it is under heavy load, since Windows doesn't regulate the clocks of both the CPU and GPU and they are to the max. And yes, the HD4670 is the hottest MXM-II GPU out there. I was in mid 80s with copper mod and HD3650, putting HD4670 in there skyrocketed the temps to 105ºC.

 

Thanks Triturbo What cooling system have you?
I have not idea how may i better cooled card.
Maybe problem is more than temperatures
What do you think about the HD 4850 from MSI GT725 ? . Is not expansive and still mxm2. I have the opportunity to buy 4850. I am not sure how will it work with 8920 (especially temperatures)
Is 4850 hotter than 4670?
Is 4850 a good choice?

 

You must definitely, read it DEFINITELY, make a new cooling for HD4850. Let's just say that there are tons of stuff that mater, and I don't have the time to explain it all. As for HD4670, place a 0,5mm thick copper shim between the core and the heatsink and it should probably fix your problem. As I said before, you have to check it yourself, since I'm just guessing here, there might be parts of the heatsink that interfere with the GPU and so on. The fact that it was made for nVIDIA GPU speaks enough for itself.

 

Ok, i will try a copper shim

Is really 4850 so problematic card ? Is more problems than profits ?
Seller offer me a card and heat sink from msi. Maybe is worth to fight for performance
I am confused.

 

The heatsink wont work for you, it has different shape than what you have. Maybe you could use some part of it, but then it involves oven, desoldering, cutting new pieces, gluing them together and so on.

 

HD 4850 is MXM 2.1 but not form factor II. It is form factor III. Simply put it won't physically fit in the 5920G.

And yes the 4850 is hotter I have owned and ran both cards in the past

How is it going Triturbo? I remember running the 4670M OCed heavily at 55C in Crysis 2 lol. Then again C90P cooling.... actually for old time's sake I installed Crysis 2 on the M15x this week. The 7970M laughs at it a 1080p and max settings all at stock clocks lol. If only the 4670M had more memory bandwidth it could really have smashed the 3870M!

 

Doh, 55ºC, are you sure? If it's true, it definitely wasn't pleasing for the ears As I said before, I'm doing something relatively radical, but time, oh time. All I can say is, watch this space and it will be my very last cooling upgrade, so yeah, it would be massive Stage III - Super Cooling

 

I remember i read ur thread like 4 years ago when u first made it

Is this STILL ur main gaming rig? How does it handle new games?

If it is thats awesome, i used my x9000 and 8800 GTX until late 2011 or early 2012

 

So, so, but I don't have much time to game lately I love this thing, that's for sure

 

Hello
Still I can not work my 8920g with 4670 correctly.
It was from msi ex623 .
When I started laptop always offed after 40sec -60 sec . Can not checked gpu temps in win 7
Today I tried start the laptop with no cover and I am shocked because teperature on heatsink near core is very hot. It almost burn my finger
Any idea ?
Acer 8920g , 120 w charger

 

What you have used to replace the thermal paste/pad?

 

I used a noctua thermal paste and I placed past correct. still i am not sure that a card is working
My previous card 9500gs had normal accepptable temps with conventional heating system
I am used yet any pad. In my opinion it is a cosmetic and . Before i must know that card is correct
I can not belive that working card have from 0 to 70 degrees in 10 second.

 

Believe me it could do much faster than this. You have to disassemble it and check if the core makes good contact with the heat-sink. HD4670 is the hottest MXM-II GPU, so don't be surprised that your cooling is struggling. BTW Do you have any picture?

 

What picture ? A card photo ?
can not make any printscreen - is no left time to make this

 

I mean does it display anything on the screen?

 

Everything is in ok the screen
The system starts about a minute. Safety switches off after about 90 seconds
I thought the most difficult is to loading system and after will be ok

My previous card was nvidia. Now I have ATI and I have not uploaded the drivers for ATI. Is this a problem?
What is a most efective way to colled this card ? heatsink, copper , thermal paste ?

 

Since it's booting fine, and you had nVIDIA, have you cleaned your drivers? Download DriverSweeper, enter in Safe Mode, clean the nVIDIA drivers, than reboot, install ATi drivers, reboot again and it should be fine. As for the thermal interface material, as I said, I don't know what is the spacing between the GPU's core and the heat-sink. That's why I suggested to take a look if it made a good print on the heat-sink. I'm assuming that it's better than mine, and you only need thermal paste. I recommend MX-4 as it is easy for application, among the best performers and cheap. Just a rice sized blob in the center of the core should be enough.

 

has this thread been hijacked or not yet? 24 pages seems oversized for what the title implies.

 

You just did it.

 

Is not enough time for change a drivers. As for the space between heatsink and the core is probably ok because there are traces of paste on the heatsink. ( I have got a somethings like springs - I marked this in photo . I have no idea how cool the core. Same paste is not enough. I changed the Noctua paste and gained 30 seconds of extra work laptop. If the card is not damaged it's probably my standard cooling system is too weak.
I still can not believe the card is ok (after 30 seconds, the temperature of the core is as great as if it was a short circuit, and burns my fingers.)

 

They get really hot, really fast. It's not the best cooling, neither is mine, but it should be able to boot just fine. You'll probably have issues with games, but it should boot, so it's not the cooling. What do you mean a trace? It has to have a full print of the core on the heat-sink, otherwise something is not right. It should not, but check if the heat-sink and the GPU fit perfectly, since it is made for different GPU, and if this is the problem for both to not contact well. If there was something on the way of the heat-sink and you've tighten it all the way down, the chances are that this component would need to be replaced. Have you changed the CPU paste as well, as it seems that they share the same heat-sink?

 

Yeah it was 55C! Shame it died. Never had the chance to voltmod it lol

and yes all 4 fans spinning at 11,000 rpm. I upgraded the the stock 9,500 rpm ones. They weren't fast enough

 

Old thread but looks like it's still active. Question, does your VGA / DVI / HDMI / Display Port (whichever your laptop has) work with the 4670 card?

 

Everything works just fine

 

Hello
My 4670 probably died. I forgot remove battery when i inserted the card. I saw little sparks on joint mxm. When i turned on the laptop does not show the picture. Black screen.
It is a totally dead ?

 

Seems to be yeah ._.

 

Probably the MoBo's power regulating chip. But yeah the chances are that you've fried the 4670 as well

 

Does it boots without the GPU, or with different GPU?

 

Of course laptop boot with another card.
I hope rescue my 4670.
Is baking a good option to temporary rescue this card after fried ?

 

Baking wont fix a fried component, that's only for stress induced damage to solder.

 

Any chance for fixing "fried" card (except baking ) .? Maybe resistors or capacitors changing ...anything
Msi 4670 is hard to find on ebay that i try check every possibility

 

Repair shop Otherwise you pretty much lost it, and you can't find it anywhere.
