Hi ;-)

I can get an acer 5739G-664G32MN (T6600 / 240m gt / 320gb HDD etc) for 200€ should I buy it? It is second hand but its looks decent.

Depends on what you need it for. Seems like not much of an upgrade compared to your acer 5520g.


@Avora

sorry, i cannot help you with your problem, but i got a question regarding your gpu: Did you just have to change graphic cards or did you change heatsink/fan as well? I´ve ordered a 6770m, too, but still don´t know how to change my gpu

Acer aspire 5253-bz877. Everything was startin to get slow so i went ahead and reinstalled windows (now i'm wishing i hadn't. I installed the wrong os and the drivers and support tools are all gone. i downloaded and installed a knock off version of windows home premium, but still nothing. I cant go on the internet and the wireless network adapters are gone -God knows what else is missing. what should i do? lookin at the install now the display seems a little stretched.

Did you just have to change graphic cards or did you change heatsink/fan as well?

MXM is a standard, so positions of memory and gpu-die are the same

@Avora

did the problem occur after installing the GPU or the CPU?
maybe try to flash your BIOS again...
What is your VCore?
Unfortunately, there is no way to control fan speed via any software.

Hi guys. I just got a 5739g, installed a P8700 and a HD6770m. Everything went well, Arctic Silver 5 was applied and all appeared well.

Since putting Windows 7 on it, I soon discovered the fan will not respond properly, it works fine until I load the CPU up with Prime95 for example. Then the fan mysteriously stops. HWmonitor also shows that the Motherboard temp drops from 40-50 degrees c to anywhere from 0-20 degrees.

The fan will then do a super fast on and off, as in revving up and shutting off again for a couple seconds. This means the temps go through the roof and I shut prime down near 80 degrees.

I thought I would force the fan on with the GPU BIOS but seems that it wasn't wanting to flash correctly, so bottled it. I have also tried SpeedFan, but nothing appears to force the fan on when I want. Would prefer not to pull a cable to force it on, but if thats what it takes, I'd consider it.

Just to be clear the GPU is fine, and Furmark will push it to an expected 80 degrees, on standard settings. The CPU will sit average at 35-40 degrees. But as I want to play a few games with this I want to know that the fan will work properly. Apologies for the long post. Want to give as much info as I can.

One option of solving this problem - cutting a white wire, that is connected to a fan and motherboard. It make rotate fan on the maximum speed for all time - but it will be loud.

Another option - it can be broken connection of this white wire.

In addition you can re-flash your BIOS with standard 3310 version.

I haven't actually had windows installed with any of the other components. I ran a live boot of Xubuntu to check the existing hardware. And the fan was just the same then.

I'm also having a right nightmare with the 6770m drivers. ATI thinks there's no "Proper Hardware connected" or something similar. Found an old driver with CCC 11.2 which installed fine.

Installing the graphics card is simple. 4 screws and the card pops up. Remove any old paste and apply some new, push the new card in and screw it back. The processor was more awkward, but I managed.

I have just noticed now actually, after the CPU gets hot, the fan does actually come on properly when the temps come back down. But wouldn't want that in a gaming situation. May have to cut the wire. Don't worry, I know how to use a soldering Iron, if I need to reconnect it.

I have also put the latest standard BIOS on to the machine. No difference also. Think that the motherboard temp sensor is to blame here actually. But never mind. I haven't changed my Voltages anywhere as yet. I wanted to see how the P8700 managed first.

EDIT: I have done some more. Ran up in Ubuntu and it seemed to work fine. Although it overheated and shut down. So I have cut the cable. Fan runs flat out as expected. Just want to know now if I could run the fan on reduced voltage fine? Would be interested in installing a Potentiometer which could be placed on the bottom cover so I can choose my fan speed. Will explore some more options like simulating the PWM from the motherboard, as thats definitely to blame. Temporarily just very loud now.

Hello, after some time, even I'm back on this forum . also I am interested to radeon hd6770 (the 240m gt sucks) .... For anyone who owns it, I would like to do some questions: First of all, How work the hd6770?, are there any real differences from the 240? And in games, how it go? Temperatures are higher than the 240?Coupled with the C2D x9100, do you believe that could give some kind of problem?
Thanks in advance

[Avora]

Ok, new issue. I'm seeing the Bios flashing problem, GPU-z sees the file size as 128Kb, but all ones available on TechPowerUp are 64Kb. Even the original Dell Bios which this card is. Possible that the seller from China put the wrong size Bios file on my card? Would it still even work ? Would explain the stupid driver problems I have been having. Will try to flash from a DOS usb later on. But this is becoming a pain.
If anyone with a 6770m could get a copy of their bios from GPU-z and tell me the size that would be great.

EDIT Correction, don't try to flash a smaller BIOS, had to reflash the original BIOS blind. Phewww. Still confused why its being odd with me though. I shall continue to modify this existing BIOS. By the way, anyone who is interested in this card. The temps are fine, never goes above 80 even in Furmark. Just standard settings mind.

As I understand from peoples posts - powerfull CPU plus 6770 - overheating. You ought to have very good thermalpaste (Arctic silver 5 for example) and do undervolt to your CPU. For example, I have the same CPu as you and it works very good on 1.0875V. With overclocked gt240m my notebook don`t overheat.

Maximum temperature of my videocard is 72 C, as I know in our notebooks 6770 heats to 75-85 C.

If you are interested - search couple of pages. I`ve posted the design of copper radiator, that cooles my CPU to 79-81 C at maximum load.

[Nik 7]

Ok, I am interested in your project of the radiator, but to tell the truth I don't understand where to go positioned , I suppose on the cpu? In any case, could you post some pictures of your work?
Thanks in advance.
