Fastest Acer notebooks in the world - 6770M owners club.

It's time for MXM machines to take back the crown.

The 6770M is specced as follows:

480 shaders
8 ROPS
128bit GDDR5

The MXM-A modules come clocked at 725/900.

The core voltage is adjustable via a bios edit (using RBE) and flash to 1.1v, this seems to affect memory speed more than core speed.

There are special rules in the bios to select memory speeds and voltage, they are only reduced on battery power (to prevent flickering) and the voltage is linked to memory speed (since the voltage has more of an affect.

I've settled for 850/1150 for 24/7 clocks myself

 

Hi guy, I have the same computer (7738G) your configuration look likes in your signature :

Acer 7738g | Q9200 @ 2.8GHz 1.075V | (2x4) 8 Gigs DDR3 @ 1066 6-6-5-15 | HD6770 1GB GDDR5 @ (850/1100) 1.07V
Intel 6300 ultimate-N + Bluetooth | Crucial M4 64GB + 500GB Western Digital black 7200rpm + Blueray Drive | 120W PSU | 1920x1080 LED Display

What kind of modification does you made on this laptop to accept a C2 Quad and an 6770M GPU (just a powerfull power supply) ? I have to change something on the original cooling ? which brand and model for your LCD display ? etc... I'm very interesting to know

...and congratulation for your work

Tia and sorry for my English.

 

Very nicely done.

Bronsky

 

The mods are quite simple to accept the config in my system...

If you had a Q9000 model you need to do... nothing.

PSU is powerful enough and you just need to buy everything, it should all be plug and play.

I suspect any standard 17.3" LCD should work but mine is an LG, I would recommend trying the hannstar 1080p panel as IMO the LG is actually a bit weak.

If you had a dual core model you just need a couple of components. You need to get the 120W brick that came standard with the quad core version and you also will need the quad core heatsink (P/N: 60.PFU01.001).

All the motherboards are the same in terms of power delivery.

Also if you want to get tri-antennae wireless then its a good upgrade to do at the same time as the LCD.

 

"It's time for MXM machines to take back the crown"

I agree I look forward to our little match up;

mxm 2.1 4850 vs mxm 3.0 6770! Should be very fun

Btw how far can you push your Q9200? Would be interesting if you can push it to at least 3.16ghz so we can bench at similar levels

 

It gets too hot with a card like the 6770 in my machine.

However I think I've done some damage to my heatsink from bending it (to fit the MXM-B cards that sit at an angle) so I have a shiny new one on the way.

I'm also upgrading the touchpad to a synaptics one as I have a spare top plate to fit it to

I'll loose the finerprint reader... Something I never install or use anyway.

Should get the heatsink in a week or two.

 

Nice I think mine is synaptics too although I never use the software for it.

Btw just a quick question are the mounting holes for mxm 3.0 the same space (46mm) apart as mxm 2.1 III?

I need to swap the mounting plate over to one that will fit the 4850 and having trouble finding a nice all copper one with a flat top so I can mount the heatpipe on it nice and easy

 

AFAIK they are different.

I know the backplate for the MXM II cards dont fit MXM-A.

 

Thanks for your advice Meaker, I have a dual core version upgraded to a T9600 wich means my Power supply is 90w model...

and btw does the GPU cooling sufficiant for the 6770 or 4670 (I have GT240M for now) ?

 

GPU/CPU cooler is one module so I would get the quad core model cooler, its not too expensive.

 

Yeah So I had to reinstall Windows 7 due to some driver issues, and came across the same "Micro-lag" issue again and I dont remember what I did last time. Which is great because it sucks.
Micro lag = Stuttering in games every couple seconds or so despite the average fps being over 50. It causes the CPU to overload and drop frames close to zero for a micro second hence the name "Micro Lag"
It is a typical issue with AMD drivers.

 

Not something I have ever run into im afraid.

 

Hi Meaker may I have your LCD reference or part number please ?

TIA

 

Here is a list of compatable screens (and where I got mine).

UK Screen Specialists items - Get great deals on items on eBay.co.uk Shops!

Like I say, get the hannstar one, I have the LG one.

Unless you want a cut price panel and live in the UK, I would not mind selling mine so I could get a hannstar one lol.

 

@akbisw - Have you fixed the problem? It could be a power draw issue - your power brick is choking with that beast inside

C'mon people, this thread is worthless without pics/benches

@Meaker - I don't remember if I said it in the MXM topic, but anyway - great scores

 

The thing is before the new windows 7 install I was able to get it to work. I was able to fix and and even posted on the MXM thread in Acer forums. Meaker even told me to put down the solution, but i forgot and I consequently forgot the solution as well. So, I will try everything I find on the internet, my school's over tomorrow so I got ALL SUMMER for this.

 

Yes I did tell you lol.

 

Okay, disabling vertical refresh ELIMINATED all the MICROLAGS for me. Also, on another note, Im having trouble with getting HDMI audio to work on my TV. It says it is detecting a HDMI to DVI connection and I need a audio cable.

How does 560m compare with 6770M from a gaming standpoint?

 

560M is going to be a bit faster. Similar mem bandwidth but more shader grunt.

Do you have the ATI HDMI audio drivers intsalled?

 

DO I have to download it separately? I mean When I installed the driver I checked everything and HDMI audio was one of those things.

 

Check its in your sound options.

 

Whoo, got the new heatsink.

Can now run it at 875/1125 1.1v and have it stable even during some harsh gaming sessions.



1920x1080 no AA/AF at High settings (except post processing at medium).



FFXIV bench at 1920x1080.

 

New heatsink + new drivers = 3.06ghz CPU and some score increases:

Almost 1850 in 3dmark 11:

Over P8000 in vantage:

My gpu clocks are 900/1150 in both.

 

Meaker, you have a really tough Q9200.

 

I know, if it was a more power hungry one I would have been so screwed.

Only needs 1.1375v for prime95 stability at 3.06ghz

 

Numbers... makes me jelous to oc mine as high as yours. after this week i will have some time to make a kickass machine.

 

Hehehe, I'll be waiting.

 

Excellent stuff Meaker now if and when I can eventually get my hands on a 4850 lol we can bench very fairly

If it ever happens you can bump it up to 3ghz from 2.93ghz and I will knock my multi down to 9x and remove my OC then we can bench to high heaven..

oh what joy haha

 

Hmm
I was thinking of getting a 6950m for an acer.

I was quoted 125$ + shipping on some 5735g motherboards, which I believe could fit MXM 3.0 B with only 1 ram module.

BTW I'm about to PM you KingOfInterns.

 

Really?
I look forward to your PM. Thanks Niff.

 

Hey, Meaker can you help me flash the BIOS of 6770M with rbe

AS you can see my 6770M is clocked at 300mhz for some reason??

 

Thats the low power state clocks. These are entered into when the system is in battery mode or forced to low power in the CCC.

They also stick there if you try and set the voltage above 1.1v in RBE.

The slightly bad thing is that this clock mode is hidden from RBE so you can't force it.

One thing is that 68C idle in that mode is quite a high temp.

 

Meaker, how do I get it up though? It the clocks dont increase while in a game. Thus harming my performances badly.

I just checked in GPU z that the clocks do indeed go up when I open a game. lol.

Well, I still do get microlags on MAFIA II and lags in others games as well. Im starting to think my cpu is getting old. T6500.

or the heat, I noticed the temp goes up to 90s.

 

You could undervolt it down to 1v from 1.05v. When editing the bios make sure clocks 00 and 02 have the same memory speed and voltage (the core speed should be different).

You could also grab a p8700 or something for cheap, are you undervolting your CPU too?

 

I dont even know how to manipulate my CPU. It would be great If I did. CPU never goes pass 50c even on load.
I used Saphire Trixx, and while I had the gpu on 1.1v the idle clock went to 100mhz instead of 300mhz on .9v. Also on 1.1v the software didnt let me change the core clocks or the memory clocks. I could change the clocks on .9v though and that seemed to solve the problems I had in games.

 

You will need throttlestop to undervolt the CPU and GPU-Z to extract, then RBE to edit the bios of the GPU and finally ATIFLASH on a bootable USB stick to apply it.

If you are unsure about ANY point of the GPU bios mod, say because it can brick your card.

If you don't feel comfortable let me know what settings you want and I can edit the bios for you. But once you know what you are doing it's very easy to apply to any card.

My setup is tuned for performance because my cooler can handle it.

I think with yours the best thing to do is leave the frequencies at stock (6770m frequencies are pretty high anyway) and see how low we can get the voltage. Since it's 3d voltage we are changing it should be pretty safe, might even be worth trying 0.95v and getting your CPU down to as low as possible.

 

Meaker what temp does your 6770M idles at? what about on load?

Mine Idles at 58C, about 68C on load on average. Goes as high as 72C

 

At 300/300 I hover around the high 40s, 53 at 300/1125, and 58 at 850/1125.

 

After modding the gpu heatsink a little(duct tapes lol) I managed to get very similar results like yours

 

Nice Did you sort your 3dmark scores?

 

Yes link is in your pm

 

Well everything looks fine, I think it's time to start sharing

 

Hey Meaker,
First, I'm very sorry to intrude on the topic, but I think you Meaker are the only one with the expertise to help me overclock my 6770M successfully.
I can overclock my card very easily but I need to flash it to the BIOS to save my clocks. Ofcourse to do that I have to get my original card's BIOS to alter it, and here comes the problem. My BIOS version is not being detected by any OC programs I know of. I tried GPU-z, Sapphire Trixx, ATIFlash, ATIWinFlash and ATITool with no success. All the programs issued errors about my BIOS not being supported/detected.

The only solution I can think of is for you, being a 6770M owner, to give me the original BIOS file of your card so I can use it to flash my card. I don't know if this would work or not so I'm asking you being the expert.
Note: I have Intel HD switchable graphics

Here are my card's info in the System Information:

..And here's what GPU-z and Sapphire Trixx show:

 

How come GPU Z is not identifying the BIOS version?? U sure U installed the right drivers?

 

Hey there, your GPU is soldered onto the motherboard, it's not on an MXM card like mine and therefore it's bios is integrated into your system bios.

In order to permanently flash the gfx bios you will need to extract it from your system bios, edit it, re-integrate it into the bios and reflash your system bios.

As for doing that, it's not something I have had to do and it is a bit risky but there are those that have done it.

 

Ok, do you have any idea as to how it's done? A link or anything useful to start with. I really want to do this safely and perfectly :/
And is it more risky than flashing just the video card's bios? Probably, due to the possibilty of ruining the computer, in which case and external BIOS programming would be required, right?

EDIT: I just did some researching and found absolutely nothing useful.. I don't want to do anything with the hardware/soldering/disassembling. And in case I can't do what it take to flash my system BIOS, is it safe enough for my laptop to have the video card overclocked everytime I want to use it?
Thanks in advance, +Rep for helping Meaker

 

The easiest method is just to have trix boot up and run with the system (its in the options) its a perfectly valid and safer way of doing things.

 

I read on some forums that making an OC software run on Windows startup and overclock your GPU might reduce it's lifespan. What do you think of that

I don't increase the clocks that much and the temps are almost always ~70 and less than 75 under load (gaming)

 

Technically it will but that's true if you mod the bios or not, you are running it at a higher frequency, that will increase wear, but if you keep the temperatures sensible then it wont make much difference.

 

Ok, thanks for the help. I increase the clocks to about 850/905 1.055V so I don't think that's much of a difference from the stock 725/800 1.05V
