6770M GPU Z by akbisw, on Flickr

 

so, the gddr5 you got o/c is running at 2000 effective at 4000 when its stock it would be 900 effective at 3600 now thats 400mhz extra on the card and the 75 mhz extra, so i image that you need the cooling not for the gpu but for the memory,

also other qestion is, does the card have a temp senor for the memory on it?

the reason i ask is because, it will help me out alot. i will able to figure something out.

i will be honest this is a mod i have never tired, so thats why i am making sure its right and will work. and be very good at what it does.

 

Speedfan doesnt recognize the sensor but every other software including GPUZ can read the sensor temp in the sensors tab

 

we'll i might have a mod that will work, but you need to use a solder iron, but this mod that i am using will be homemade lol, and i will try to be using it off of a go 7800 heatstink, from my old card. off a dell e1705

could you tell me the temp of the memory, i am just wondering, idea temps and maybe just a quick gaming temp, i am just trying to see how hot is runs, so i know how i can make this mod

also there is this awesome montioring program called HWinfo it comes in 32-bit or 64-bit its awesome, it will read every sensor you have.

 

take some pics if you have time. I wanna see.

 

i will be upfront honest, it wont look the best, i dont have study hands like i use to, but its just a test, i have these copper fins from other laptop i had, which dont work, and i took about 4, and i am going to solder them togather, and then the 7800 heatstink has a copper pipe line, i was gonna cut a pieace with tin snips and make a "L" and solder it to gather, and then make a piece and solder it to the cpu copper pipe line, but i got to find a few more pieace's i got the blue thermal pads off the 7800 which will fit the ram on the 6770m ram.

I might might the copper ram stinks bigger, or might go on ebay, is there any way, you could tell me the size of the Ram on the buttom they will all be the same size but you wont have to remove anything, i just need like the size of them, so i can them the pieaces the right size,

and yes i have been working on this all night, and i have not been to bed, i take modding as a hobby, lol

 

ok we'll here is a beta test, right now i am just trying it out, and seeing what other options i can come up with, this is homemade %100. i did not buy anything. they are double sized they are 3/4 x 3/4 or 0.75 by 0.75 inchs

this is the top side of heatstink now this is pure copper



this is the buttom which will be used for the ram since there is not solder really on that side,



sorry if they are crappy, i have not modded in a very long time, and my soldering skills are still kinda, but soldering to copper is not easy lol.

 

I got a test version of GPU-Z which shows the correct Rops (8).

 

Okay, I did read throgh all the posts here.. There is just a few things I want to add for both of you. Yes my GT 130M is ddr2, but it is till cooler then for exampel my 9800M GTX or 9600M or even my GT 310M. Also guys, you can't cut the heatsink/heatpipes there should be a kind of liquid in there, as far as I know. Also adding a second fan is kind of out of question since it is very tight in there.. What I can thing of my friends are some mods to improve the airflow.. The fan it self does it very very good.. I live in 2 diffrent places now I'm at home 2 where I have nothing but only my ACER and my HP at home 1 where I usually are I have everything, my tools, my CPUs, my thermal past and all the other tools I need to fıx a laptop so I must wait untill tomorrow to do anything untill I'm going to think about the theory part.

 

first time i hear anything like that. can't you bump it up using ati's control panel or something? also, when you switched to 6770, did you load a new vbios? how is it done, i forgot

 

You seem to be disabling powerplay by ocing otherwise it stays in low power mode. Have you tried setting battery and plugged in profiles to high performance?

 

I had powerplay disabled when i first saw it. That makes total sense now. I didnt read it through and disabled it out of a whim. So, sorry lol. Thanks again Meaker.

 

as far as the copper pipe line, there is no liquid inside of it, i have taken 2 apart and it's just like a copper pipe.

i am going to finish up the other 2 pieace's and then i have the copper pipe from the 7800 did not cut, i am going to get a blow torch and blend the copper and make it the size i need it to be.

now my qestion is, to you guys who have the 6770m about the power side of the board, how are you guys keeping that cool? or do you not even bother? because if i need to make a mod for that i will as we'll,

 

I don't know what "copper pipe line" are you talking about but if you're talking about a heat-pipe there is or rather was liquid inside it although it tends to evaporate (that's how this thing works in the first place).
I would strongly advise against using a heat-pipe that has been tampered with.

Here are some basics on how heat-pipe works.

 

it is off heat-pipe from 7800 go heatstink from e1705, (card bad) the whole heat-pipe is in contact,

after talking to a few of my buddies, who ones is a plumber other is my grandfather and knows alot about pipe work.

i am going to pick up a blow torch from my grandfathers and i am going to blend the pipe the way i want it to be.

 

It's not a pipe. I hope the plumber thing was a joke.

 

Dude, I did not understand your post. As far as I have read it should be some sort of liquid inside the heat-pipe, is this right or not?

Figured it out:
"At the hot interface within a heat pipe, which is typically at a very low pressure, a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor condenses back into a liquid at the cold interface, releasing the latent heat. The liquid then returns to the hot interface through either capillary action or gravity action where it evaporates once more and repeats the cycle. In addition, the internal pressure of the heat pipe can be set or adjusted to facilitate the phase change depending on the demands of the working conditions of the thermally managed system."

this is going to take a little time to come up with a plan, but i have a pretty idea of how i am going to do it, its just cooling the ram on the back of the video card, but i wanna do it right,

and i need to come up way to cool the power resistor's,

the reason for the copper is because its easier to solder then any other kind of mental. and plus copper is a better cooler type of mental then say Aluminum

 

I can't come up with anything unless I'm getting my Quad to work. I'm however heading home tomorrow and hopefully I'll fix something.. I'll atleast take a closer look on how this works..

 

am not good with bios's, but hardware modding, give me some time, and the internet, and i will come up with something, i will be working on this while am at work tomorrow some,

because i wanna really get a mod for the 6770m so we all can enjoy it, and not worry about over heating on the ram, there is like 4-5 ways i am thinking about, but all ways have a benfits and non benfits and i want to make one that has all benfits

 

Well, I would be glad to hear about any ideas

Gulkor, take a look here. Don't mod your Heat Pipe

6770M is fine and is very cool never goes over 60C in mine.
Its the damn CPU that Im worrying about. That is one hot chip. When I get my new heatsink I will be able to tell you how that works out.

 

Do you have any backup plan if it does not work? I wonder if I should get the same CPU as you if the Quad does not work.. I actually wonder if T9900 is cooler. Maybe I just get the T9900 to see the diffrence

 

hey akbisw,

just a few quick qestions,

are you running the laptop's fan at full speed or letting the laptop control the fan?

when you ran the card at stock speeds clock/memory speeds did you need the extra fan? and also do you think if you ran the fan full speed in this laptop would you need that extra fan?

and if so,

what size is the ram? like X by X am just wondering because am thinking you could pick up some of these's at newegg

Newegg.com - Swiftech MC14 Copper Heatsinks only

and just cut them down a little, and that should cool the memory on the back,

if that dont work i will go back to the drawing board.

 

I havent cut the white wire yet So laptops controlling the fan. Its not at 100. The 6770M is totally fine by itself. Only you overclock it, the load temperature can reach 70s. Other than that it stick around 40-48 idle and 48-60 on load. But the real problem is the processor. When I replaced my broken fan I had to rip apart the heatsink of the cpu that was attached to the fan cover. So now the heatsink of the cpu and the heatsink of the Gpu has a little gap in between. Also I have numerous scratches on the heatsink surface. So with the new heatsink and the fan every issue Im having will be resolved. I made the cooler pad just to overcome this problem for the time being as the heatsink is coming from Singapore. Trust me the GPU is totally fine by itself. So i dont need the cooler for the gpu to be honest.
But I kind of modded the gpu heatsink a tiny bit. I actually raised the heatsink by half an inch or more so that the Gpu core is tightly pressed against the heatsink. That alone brought down the temp by 5-10C
To Tunay, I did undervolt the cpu from 1.225 to 1.125 so I dont think T9900 would be much different.

 

i was gonna buy a copper mod for gpu off ebay and use that, but since you told me it will be fine by it self, i am now going to buy the 6770m, the only qestion is, can this cooling handle a quad+6770m and be fine.

With the white wire on the fan, i did not cut, i just push it out of the white solid connecter, so i can push it back in, i just left it out because i get cooler temps,

unless my intel t6600 at 3.0ghz would be fine, i see not reason to get a T9600/T9900 when i get 3.0 with my T6600, so the only reason for me to get a quad would be the 2 extra cores

if i can do a Quad-core am going to get q Q9000 2.0/6mb/1066 or Q9100 2.26/12mb/1066

now that i know you dont got to mod the 6770m i can dig that, i want to put a quad in here,because a quad+6770m in this laptop would be awesome by far

because i got it for free from my buddy lol, so if i can put $350 for quad+6770m am all for it, no qestions asked

 

akbisw its likely the E8435 are the leakiest chips they made, so IMO a T9900 would run a little cooler.

 

For those who are intrested:

I'm going to try the Quad Again with Stock BIOS. Most likely it is not going to work, but worth a shot. I have also still not recived my Antennas or my keyboard..

Also V0.3309 is old BIOS while V0.3310 iş the newest, I'm going to try 3310.

 

going back to the vbios thing. that mxm thread is too lengthy
akbisw, what all did you have to do to make the 6670m work?

 

He had to plug it in and reseat the heatsink, along with direct downloading the ATI drivers (the auto downloader does not recognise it).

 

Okay I have one bad and one good news to you guys..

The bad news is, the Quad didn't work. Even with the BIOS akbisw uses. Well, it did not suprize me, but worth a shot.

The good news is, I took my ASUS apart and got my 8GB 1333Mhz Modules in my Acer and the P8400. And then....no just kidding here comes the best part, I was able to have it run at 1333Mhz!! IDLING AT 27C!!! (That is about 20C lower then T6500!) GT 130M idling at a only 37!

Testing diffrent stability tests now...

--

Ignore that above, not stable at all.

 

You could use memset and try slacking off the timings a little.

 

Hahah lol. You sounded so happy and then it wasnt stable. That happened to me quite a bit with 6770M when I was overclocking it.
My card is not stable at Meakers configuration. I will try to push it again when my heatsink arrives.

 

Okay, I got my CPU Stable, I mean the P8400 at around 3Ghz, 1333Mhz, but that is only with one core. When I enabe both cores it is not stable anymore, that means, I have to increase the voltage.. I'm also trying my diffrent RAM sticks.. For now, it looks like I can only boot up with 1 stick, again, I'm out of power.... But I don't get it, my system is overall so much cooler and not warm at all...

UPDATE:
When my G.SKILL 1333Mhz sticks are installed I'm not able to set FSB to 1333Mhz. But I'm able with the stock RAM sticks... Still only 1 core. I'll update as I'm still doing some diffrent tests..

 

hmmm interesting, i wonder if we could use a asus bios to support the quad in this notebook, there has got to be a way to unlock the quad-core feature in the bios,

but the overall good news for me is i can just pick up a 6770m and be ready to rock with my t6600 @ 3.0ghz

but bad news for i cant use a quad so there is not ponit for me to upgrade to any other cpu but a quad at this ponit

 

Okay, I'm not able to overvolt by software and I'm not going to do a hardware mod. This means I'm not able to set my FSB to 1333Mhz with my both cores. Okay, at this point. I wonder if I should test my T9600 in this laptop. It means, I can be able to run at 3.33 Ghz (3.30Ghz). BUT, if I get the T9900 I'll be able to overclock to 3.83 Ghz. I hope, but most likely not is not going to allow me 1333 FSB..

There is also isin't a CPU voltage option in BIOS..

UPDATE:
Okay, I'm just levin this here. I'm not going to try overclock anymore, just going to work on the BIOS so I can get the Quad Core to work. If I can't do this, then I'll just sell my CPU (I got it very cheap so can sell it easily) and get a T9900..

 

Love my quad support, but FSB overclocking in bios would be really nice.

 

I wonder what will happend if I try to install your BIOS on my laptop

But really, I think this laptop can handle Quad. But as far as I have understood, the 'modified BIOS' only gives the extra options, which is OK but I'm now looking for one who can check microcodes or something. Because akbisw got his 45W CPU working, so hardware-related, it should be no problem to upgrade to a Quad Core CPU. But that BIOS thing is starting to me off...

 

Im happy with the performance so far. I can Game at Max setting on my native resolution (1366X768), and 30frames on my hd tv which is what I wanted

 

Which games do you play?

 

Mainly Battlefield Heroes(Get like 100+ without trying). Which doesnt really need a GPU AT ALL LOL.
I also play
Battlefield Bad Company 2, on tv, Maxed(except shadow on medium, NO AA, 1xAF) at 1080p I get 28-38 frames, at 720p close to 60 frames Maxed.
Mafia II I get 30+ frames No lag at 1080p Maxed 2XAF NO AA
I also need to benchmark with Assassins Creed 2
Getting Black Ops tomorrow, so will let you know How that works

 

IIRC you have an insyde bios and I have a pheonix bios, so flashing is likely a bad idea.

As for the CPU thing remember the dual core CPU is "45W" and mine is also "45W", mine has the potential to go MUCH higher when ocing, it is twice the silicon after all. I have 3 full power phases going to the CPU alone.

EDIT: BTW please note with my 6770 that more core voltage is higher than stock (1.1v vs 1.05v) so thats why my clocks are so much higher.

 

the acer 5739g have a pheonix bios, because when i thought the bios was corrupt i did looking up on google and there is big long theard on it about corrupt bios and acer laptops and the 5739g is in fact a pheonix bios, i will have to find the thread, it will take me a day or 2 day to find it.

 

Lol just boot the system up and go into the bios. Or even look at the first screen.

 

I would stay away Black OPS..AWAY.

Guys, it is Pheonix..

 

tunay cleared it up real quick , i was just looking on google for it to, there has got to be a code in the bios to unlock the quad,

is the acer 7738g have 2 fans or 1? i am just wondering

 

Well, to mod that BIOS isin't easy, and it is easier for them all for me to just get a new CPU.. But there is still something in BIOS, I belive

7738g also only have 1..

 

It is a 0.5A 2.5W fan though lol.

 

That can be true I don't know I only looked for how many fan it had

Also, Meaker, do you think it is a good idea to 'upgrade' to 7738G fan? Maybe that can bring the tempratures even lower..

Also, for you who is intrested, there is something wrong with ACER's designers, I took the backdoor off and I have 10C lower on CPU. And I noticed that there is NO intake hole for the fan.. Poor thing.

 

Make sure your fan is removable, if it is then I think it would fit.
