I am trying to do the "Ultimate" G73jh upgrade and I have power related issues.


So I have the most "basic" G73jh, with i5-430m and 5870m.

This version is the one with the brown MB, with only 2 memory slots.


What I did:

- Opening the whole laptop

- Swapping 5970m to 7970m

- Blind-Flashing 7970m vBios

- It boot ! But GPU/RAM frequency stay at 450/300 maximum, because of my 120W PSU I think (throttle), So I ordered a 240W One

- Swapping i5-430m to i7-920XM

- It boot but I almost didnt use it because I was affraid of my weak PSU (dont want to burn it !)


Then I received my new PSU, from ebay  ( http://www.ebay.fr/itm/201638674476).


And... Nothing change !! My 7970m is stil throttling. And I cant OC the 920XM, if I go over 70W TDP, the G73 instent shutdown :-/.


I need your help to be sure Its a PSU related issue, and not something else, like my mobo etc. I dont want to buy a 100+€ PSU if this is not the problem.


As my G73 is still out of his case, I manage to solder the PSU wire directly on the MB, and then I measured voltage during full load (prime95).

IDLE 19,4-19,5V     LOADED: 19,3-19,4V

Not that bad !


I am very confused because the PSU seams to work. I have no oscilloscope to watch the signal in real-time...

For sure it is not a real DELL but if voltage is not droping, whats wrong ?


Its very frustrating to know that everything work but can't be "feeded" with Amps !


Any ideas ?


EDIT: All temps are OK ! Furmark : 58° GPU... (because of the low Freq :-/ )

EDIT2: new info: I tried on battery, It is the same, is it a common behavioor ? (My battery is almost dead, only 30% capacity)

EDIT3: Do you know if the "metalic" part of the case (under the keyboard) have somthing to do with the power delivery in the mobo ?

EDIT4: I reassemble the laptop, so no, the metal plane have nothing to do with ground...

Some News !


I received the DELL 330W power adapter and I manage to "convert" it to G73jh jack.

It work well but didnt solve anything...


BUT ! I flash another vBIOS, a Clevo one (enduro disabled) and now the GPU run at max frequency !

So for the GPU part, its all working well..


Still have problem with CPU, my PC still instant shut down if I go after 70W tdp (while executing prime95)


So I did a lot of test with ThrottleStop, HW64 and Prim95.

What I see is that, when I raise TDP, CPU Frequency raise (wich is the desired behavior) BUT the BCLK become crazy and dont stay at 133MHZ !

It Jump to 150, even 170 wich mean my DDR3 SIMMs are way beyond the stock 666Mhz .

I tryed to disable Turbo Boost in bios but by doing this I cant use throttlestop anymore :-/.

I also tryed differents bios (211,213, modded 213 V5), nothing chage.


If anyone have a G73jh with a 920XM/940XM can do the test... just run P95 and watch frequencies in HW64 and see if mem clock become crazy.

In my setup the computer fail at 750Mhz (wich is high compared to stock 666...)

I think HW64 is wrong, its not able to read the CPU multiplier in real time, against it compute a fake BCLK value...

I think that because CPU-z's frequencies are all OK.


So... My 920XM do not want to eat that much power ! Or maybe may MB do not want to feed it.. That would be strange since the 7970m work just fine. I am even able to overclock it (975/1400 from 850/1200, stable 1H FurMark (95° top temp)).


I'll measure the Vcore to see if there is "glitch" or something like that.

Hi, I did same upgrade as you with similar problems :-). TnF had on forum attach file named as clevo.zip (pack of clevo 7970m VGA bios). I was able using this VGA modified bios to1.10V overclock my gpu max on 1095/1560.

Re-Hi jurom !


As I tell you in the other thread, my main problem now is the MB.

Mine is too weak to power the 920XM at full speed.


And you are right, I did the same mistake with the vbios...

Now I have flashed the right vbios and it work great !


But at 850Mhz it is very close to the tdp limit...

In some games its Ok, but in others I have to underclock (mainly in the last tomb raider).

(Even with the undervolted vbios)


I am thinking about adding a secondary heat-pipe/fan in the dvd trapdoor :).


Thank you anyway.


Edit: with the vbios i use, I have not sound over HDMI and VGA isnt working too. Is it the same for you ?

Edit: At stock clock (850/1200), undervolted vcore (0.975v), I get constant 92° in FurMark after 20 minutes.

      Hello everyone! First of all sorry if this isn't the correct forum to post this.
      I bought a laptop few days ago. The laptop is Sager P150EM.
      Cpu:i7 3610qm 
      Gpu: amd hd 7970m
      Ram: 8gb
      Os: windows 8.1 pro
      So my problem is that everytime i install the amd driver after the intel driver my laptop freezes or gets a bsod or something that stops it from working. Any help would be appreciated. I saw somewhere something about vbios does this matter anywhere?

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Hello all! I have been researching upgrade paths for my M17x R4 and I have decided on the GTX 1060. Now, I was given this laptop with a dead GPU, and I had an M17x R3 already. So I moved the GTX 560m into the R4 which has worked fine. Now as I understand it a few things are needed for this upgrade including the 120hz panel and the ability to disable the legacy ROM for a pure UEFI boot. I have the 120hz screen, but the 560m uses the GF116 architecture which does not have a vBIOS which supports GOP. So I am thinking the only solution is to buy a cheaper "in-between" card which supports both boot modes, which will allow me to disable the legacy option in setup. Does anyone have any suggestions as to what cheap card to buy as a transitional part? I have been considering a 765m but I am also wondering if there are any other good choices.

      hello everyone, I have a MSI GT683R with a dying (pretty much dead actually) GTX560M in it.
      I am looking to upgrade it to a new GPU, I have found a AMD Firepro M6100. (I first wanted to upgrade to a GTX970M, but that's too expensive for now... and corona is also making things difficult) I have already ordered a second heatsink to modify because I didn't want to modify the original heatsink it came with.
      But, my question is. Does it even work in this system? I have heard of people getting it to work in the barebone variant of this system. But I am not sure if it would work in the 'fully loaded' variant.
      Also, my games are mostly RAM/CPU dependent and I am looking for a little extra power in this system. I have found a I7-2860qm and I want to upgrade to 32GB of RAM, is it possible on this system? the sticker says 'max. 16GB of RAM' But I have feeling it says that due to the limitation of the cpu that's already on this system (I7-2630QM, 16GB RAM max.)

      Hello everyone,
      some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that).
      Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom.
      I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W 
      Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output)
      If anybody tried something like that on any laptop model, or knows the matter, I'd like to know
