[REQUEST] Acer Aspire 5750(G,Z) & 5755(G) BIOS Unlock

[McBride]

I tried many ways, but for me it's impossible control fan speed...

[McBride]

This BIOS mod it's perfect! thank you!
But I have another question. I know the memory upgrade depend from CPU, Chipset... etc etc...

I want know if I can install with this bios version:

2 x 4Gb ddr3 1600/1866/2133

or

2 x 8Gb ddr3 1600/1866/2133

I read 4Gb 1600Mhz works fine, but 1866 or 2133?

So even after bios mod we cant control fan speed ?
This blows its not even hot here, would have been great if FAN speed could be controlled as when i start the laptop fan spins at full throttle.

So much for low end gaming laptops. Should have saved money and got a non G version and used that to pay for an XBOX or PS3 title.

Hi akbar!

Does the hackintosh version of your modded bios have the same tweaks as the first one? I have both win 7 and osx 10.8.2 installed, so which one would you suggest?

best regards,

honfbert

Sorry! I should think before I ask. I got OSX, therefore it makes sense to take the one with optimizations for OSX... *facepalm*

On my Aspire 5750G I bought and works fine:

8Gb DDR3 1600Mhz SAMSUNG kit 4Gbx2

[honfbert]

I tested both versions on my Packard Bell LS13HR. With the hackintosh version, when in Win 7 (I use both, Win 7 and OSX 10.8.2), the fan control doesn't seem to work. Fan is actually off. Changing fan values in bios didn't have any effect. Now using the first version and everything seems to be fine. Both OSes boot up and run smoothly with UEFI on. Didn't mess with the EFI stuff yet, though.
