I saw the reference to JXA, also, but it doesn't appear to be a different model, at least not one that's out now. On the ASUS web site, inputting "G750-JXA" as a model number for support got me an error message.

asus have not JXA model for G750, so where are you look for this model? others, i think you upgrade to 8.1 or change ssd then upgrade to 8.1, it is ok, you can use ASUS backtracker tool to change image to new SSD.

"JXA" is mentioned in this thread, among others.

See the screenshot for "G750JXA" BIOS.

I bought 750jx a few days ago and ran the OS on the 750gb HD, felt so extremely slow and bad. Took forever to do anything, login was so goddamn slow.


I Had never opened a laptop or changed/installed a new HDD before.
But it was pretty easy and straight-forward!





I plugged in my USB-HDD (had no other usb-pens =( ...) and ran asus backtracker
Turned off the computer
Removed the original HDD and placed the SSD where the original HD was installed.
plugged in the usb-hdd again (the one I installed the os image on with asus backtracker)

and it installed and booted up perfectly

turned off the computer again and installed the original HDD in the second slot

and formated the 750hdd


then I used windows update to install a few required updates so I could have access to the windows 8.1 upgrade

upgraded to windows 8.1 through store


Its easy and fast to do but the whole download process seem to take forever even with 100mbit



Also, I did not update my realtek audio drivers, for some reason I got very bad framerates in arma3 when installing any other realtek drivers. 😞

Thanks for the replies, anybody else want to chime in?

I removed pretty much all the bloatware from mine. I also updated my BIOS, gpu driver, audio driver, undervolted, optimized, cleaned up, etc all by myself! (Its my first time doing it and Im very proud of myself)

Proof that I feel I did it right - Crysis 3 on ultra runs at around 40-50 fps. Gaming for 8 hours straight gave me temps below 68 degrees ( cpu and gpu) No lag. Boots up in about 5 sec max. No issues with sound or graphics. Amazing performance. My advice is to everything by yourself, experience it and find out everything about your own laptop. I had 1 reboot when overclocking my graphics card so I found out my limits. I had a few graphics driver crashes when playing around more. Now I have arrived at a system thats perfect for me.

If you need any help uninstalling stuff, post the names of the app here and Ill tell you if I think its safe to uninstall. If you want driver advice, post here and Ill tell you which one Im using perfectly satisfactorily.

On a side note, I dont experience any of the problems posted here by most users. Speaking popping or distorting, graphic probs, etc nothing. Its perfect.
