Hello.
So it can be confirmed that olding like G73jh can be upgraded to latest of nvidia gtx series. I must confess one thing though when thinking about this machine first thing that comes to mind is zombie
Becouse it involves merging 4mb bios file of g73jh with g73jw plus moding video bios to get standard mxm 3.0b gpu be recocgnised by system.
All this was neccessary becouse without bios mod there is not support for nvidia gpus in system bios but g73jw has neccessary callbacks and thus is involved in this mod. Even inside bios settings it is shown as g73jw now and all other programs like HWinfo shows it as that.
With original unmodded bios there is no backlight on internal lcd before windows log in screen is loaded and both fans are on full throttle constantly.
Under is some pictures and link to 3dmark11 score with standard clocks.

Hello. Thanks for showing interest in this mod. I must ask whatmachine eventualy you would install this 770m in?
Asking becouse you need modded system bios to for installing it in G73JH.

Then as it is now your machine would not show picture on internal lcd before windows login sreen and that only after video driver is installed first. Also both fans would be on full speed all the time. To get this card work correctly you would need to modify system bios on the motherboard to. I could assist in this but only if I would get really fair price for 770m and heatsink would be included.

I was just curious on the pricing of the 770m GPU as I could perform the rest of the modification myself... though it seems to only provide a minor performance gain for a high cost. For $400 I would prefer to just buy a new laptop... lol

Comparing to 5870m in g73jh it gives over 150% boost in gaming performance. And machines with 770m cost least 1500$
However you get updated chipset, new gen cpu, usb3,better keybord. All said I own g750jx with 770m and ssd but it is not worth it trust me. Screen bleeding is terrible and still I would never exchange it for my other g73sw with 680m and 2860qm cpu.

I bought an MSI GT70 and an ASUS G750JX last fall for school, but I ended up returning them both because I despise Windows 8 and just sticking with my nearly 4 year old G73JH. I'd like to do a couple of things to it to hopefully get a couple more years out of it, but if the cost to upgrade is going to be more than half what a new one would be, I'd just as sooner get the new one and reset the clock.

For 200-300$ you can get new 770m and thats all cost involved rest would be on your skill to modify gpu heatsink to fit on 770m and system bios modifying is actualy biggest obstacle as I had to desolder bios chip and program it directly with SPI programmer. But if you wouldnt mind fans noise and missing backlight on internal lcd before windows login screen then no need for bios mod.

Would this work on a g73jw?

jmhdj still waiting on that dope guide of yours to upgrade to 680m :P

I have a Asus ROG G72jh with a non Working HD5870 okay ..

to update this notebook ? :

So if I understand it correctly:

1. A GTX770M for example Aliexpress (does not matter what the) buy

2. the Bioschip against a swap from the G73JW (Original image not modified)

3. Install the GTX770M and adapt cooler

Do I need a different power supply in the connection?

I can solder, I have an esd compliant workplace and have often bioschips resoldered

even if the contribution is older I hope better I hope for a response.

I love my Asus notebook ;-)

Nice greetings from Germany
______________________________

also wenn ich das Richtig verstanden habe :

1. Eine GTX770M bei zb Aliexpress ( ist das egal welche ) kaufen

2. den Bioschip gegen einen vom G73JW tauschen ( Original image kein modifiziertes )

3. die GTX770M einbauen und den cooler anpassen

Brauche ich ein anderes Netzteil im anschluss ?

Ich kann löten ,ich habe eine esd konforme arbeitsplatz und habe schon öfters bioschips umgelötet

auch wenn der beitrag schon älter ist hoffe ich besser ich hoffe auf eine antwort .

ich liebe mein Asus notebook ;-)

Schöne Grüße aus Deutschland

Hello. I took my old asus rog G73jh laptop off the shelf and read this topic. I found a 770m video card from asus https://ru.aliexpress.com/item/GTX-770-3-N14E-GS-A1-VGA-Asus-ROG/32850818674.html?spm=a2g0v.search0104.3.85.64f0262 3vhiLAK&transAbTest=ae803_4&ws_ab_test=searchweb0_0%2Csearchweb201602_2_10065_ 10068_319_10059_10884_317_10887_10696_321_322_1008 4_453_10083_454_10103_10618_10307_10820_10303_537_ 536%2Csearchweb201603_80%2CppcSwitch_0&algo_pvid=80f0c47c-8903-457b-a572-2c3036a04804&algo_expid=80f0c47c-8903-457b-a572-2c3036a04804-13 (cheap). But I still did not understand until the end what work on the BIOS firmware was done. Can anyone understand this issue?
