MSI gx740 tuning/upgrade options

Recommended Posts

Hi,

 

I own gx740 with i5-430m, 4GB RAM, and I planned to do some upgrades.

 

Currently I did:

- upgrade SSD, move HDD to dvd drive space

- have some unlocked bios (but didn't found usage for it currently)

- have modified vbios but not sure if the values I've used are good

 

I was thinking about:

- upgrading CPU to i7-640M

- upgrading RAM (not sure which will fit)

 

 

I would like to also:

- fix broken/cracked frame around screen, but it wont be easy and cheap I guess?

- replace screen to something brighter (?) but this will probably not be worth the cost

 

1) What do you guys think about it? Is it even worth?

2) I've also see something like 'grain effect' moving grey stripes on same page elements (long time I remember it could be related to faulty bios/vbios)?

No idea for how much money you can get an i7 640m, but everything over 20€ would not be very sensible. Since you have an unlocked BIOS, have you tried to OC your CPU? You might get the same performance as the i7 640m with ~600 MHz OC on your current CPU. You also could buy an i7 720qm which would give you a better single and multicore performance, since it has 4C/8T and a 2.8 GHz boost clock. I can get one for around 20€ in my country.

Upgrading RAM is a good idea. You should check how many modules are present in your laptop, because your motherboard has only 2 slots. If it's a 2x 2GB configuration, you could buy a 4 GB module and try to sell the leftover 2 GB module. Check the RAM info in the BIOS or with CPU-Z (Memory-Tab), then you will know what fits.  I've a similar laptop with the same motherboard (Terra Mobile 1772) and I did the same thing. I put an SSD in it, upgraded the RAM (3GB to 6GB, for me it was a 4GB SO-DIMM DDR-3 CL7 module, 25€ new) and swapped out the i3 370m for an i5 520m (10€), which I plan to overclock a bit more when I get hands on an unlocked BIOS. 

 

Do you have any pictures of the cracked frame around the screen? Maybe you are able to fix it by yourself. My screen is also not the brightest, but my panel can be overclocked to 100hz which is nice. I think swaping out the screen is not worth the cost.

Even with the unlocked BIOS there seems no way to push up the voltage for any of the components. You could try "setfsb_2_2_134_98" with the "ICS9LPRS113AKLF" or "ICS9LPRS133BKLF" clock generator to increase the FSB. I was able to push it from 133 MHz to 143 MHz (stable) which results in a 200 MHz OC per Core but thats it. Maybe you have more luck.

Turned out that my 2 GB RAM module was causing the blue screens when I go higher than 145 MHz FSB. Im currently at 160 Mhz FSB which results in a 3.5 GHz single core turbo and 3.2 GHz multi core turbo. I am using an i5 520m which has a default speed of 2.4 GHz (2.9 GHz single turbo, 2.66 GHz multi turbo). I'll keep you posted.

      Hello guys,
      Thanks for this incredible forum, I hope I will learn a lot from the gurus ! 

      I am trying to make my eGpu MSI GT X970 work on my laptop   with K1100M integrated GPU. 
       
      This are my specs:
      CPU: 2.7GHz Intel Core i7-4800MQ (quad-core, 6MB cache, up to 3.7GHz with Turbo Boost) PSU : ??? Graphics: NVIDIA Quadro K1100M / Intel HD Graphics 4600 RAM: 32 GB Storage: 1TB

      I got a V8.0 EXP GDC Laptop External Independent Video Card Dock  with the express card version ( I am not really hw savy) and I am looking for a good psu to power my MSI GTX 970 4G  
      Could you kindly suggest a good PSU that i could use to power this GPU ? I am also willing to do as many experiments needed
       
      Thanks for reading my post

      Hi,
       
      I recently bought the new Toshiba RC100 m.2 2242 NVMe SSD for my Lenovo Y510p which has an m.2 port in it.
      After installation the SSD wasn't showing up in my BIOS and also not on my OS Win 10 disk management. So I did a bit of research and installed mod BIOS for my Y510p by following the steps in the link: ( https://www.techinferno.com/index.php?/forums/topic/3546-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod/ )
      There are a lot more options in the BIOS menu now.
      Even after doing the mod it's not showing up. The SSD works on my friend's "new 2017 dell gaming laptop" which has m.2 ssd support in it. I don't know what exactly to configure my BIOS to make it work. I've just done some hit-and-trial configs which have eventually failed.
      If someone can help solve it Pleasee!!
       
       
      P.S. : I can share all the available options available in the BIOS if required.

      Hi,
      In this thread you can post your requests for AMD-V unlock on ACER E5-553G and same laptops with AMD CPU's, for example Acer Aspire E15, E5-523G, Acer Aspire E1-522, Acer Aspire E1-420, etc.
       
      Now we can unlock  AMD-V function for virtualization support. In general, this method described in the article on this link: http://www.geektech.co.nz/how-to-unlock-...enovo-y700
      This way requires Windows as a system because  some tool works only in Windows.
       
      You will need this tool: https://drive.google.com/file/d/0B4NHIBM...RtQXM/view
      Extract the archive and go to the folder with the extracted files.
      Then, you need run the Command prompt as Administrator and navigate to that folder.
      Execute the command from step 1 of the linked guide in that Command prompt (H2OUVE.exe  -gv  vars.txt).
      After that, you'll have the file "vars.txt" in that folder.
      You need post here or upload to any fileserver your  file "vars.txt" and  send me the link, for modification.

      For reference, here's the EFI-table with available settings for this notebook: https://drive.google.com/open?id=0B4NHIB...WI4LW14bE0
      And here's the setting that needs to be changed:
      0x1C40B             Setting: SVM support, Variable: 0xEE {05 91 54 02 55 02 54 00 34 12 EE 00 00 10 00 01 00}
      0x1C41C                 Option: Disabled, Value: 0x0 (default) {09 07 27 00 10 00 00}
      0x1C423                 Option: Enabled, Value: 0x1 {09 07 28 00 00 00 01}

      As the title says; is it possible to upgrade the old MSI 16f2 with any pascal card?
       
      Or is the 980M the highest possible?
       
      Looking forward to your answers. Thanks
