ATI HD 7970M ON ASUS G73Jh

That looks pretty good I see you went with my idea of using the machine screws, did you find it easier? I think the machine screw idea should be added to the "how to" guide. As a matter of fact there isn't really any guides for the 7970m and the 6990m is somewhat outdated.

 

The screws that fit were 4x40 by 3/4 of an inch long. I couldn't find them at home depot, but found them at Lowe's

Don't remember which ones I bought I should still have the packaging somewhere. I just cut them down to size. I'm about to remove whats left of the thermal tapes and ad thermal adhesive. I'm also going to ad the fan tonight. I got an old chipset heatsink with long fins, I am thinking of cutting the fins and sticking them on to the copper heat pipe to add more cooling. I had my system BSOD again, GPU temps were 63''C in a game called league of legends. One of the IC chips must be overheating. Thermal adhesive plus fan should fix the issue. I'll take some pictures.

Does anyone know where I can buy a 1920x1080 screen here in the US of A AUO v5? I really need to replace my LCD.

 

Y I Wish I had £3000 spare I have been looking at a Asus g73 motherboard that I have just fixed looking at the way the lanes are ran though the board I bet I could solder on another pcie header so 2 graphic card slots ! Only thing is that u would have to rework the power circuitry massively so the output from the board was doubled to being 300w + the lanes though the motherboard are thick enough to handle the amps being pulled and I think you could get two gpus running ! @ 8x crossfire eney1 got a dead g73 motherboard so I can try and mod the 1 I've just got running lol. Really interested by this now god dam if I could get this thing running 2 of these hd7970s I'd be. A happy bunny. Already thought about the heatsink I have the vapor chambers from my gtx 580s...... stack the gpus facing each other vapor system on top of each gpu and heat pipes in the center would work very well ! Please please please let some1 have a dead g73 mobo I would love to just go n buy the parts to try this but sadly money's a pain at the mo

 

try screenintaipei on ebay, they apparently ship very fast from taiwan

 

My system never had a Bsod with this new card
I only had one problem after I overclock the CPU more than the normal
So my VRMs are cooled well
I think the fan is helping a lot and I using
Thermal pad under the coopers

I can't get the fan on there!! GRR been at this for a few hours now. I've trim down the the edge of the fan all the way down to the fins and the space between the video card and the wifi is too small even for the fins. How did you get them in there? Did you trim the fins?

 

I didn't cut it
Only the edges of the fan!
It was a lot of work to make this fan fit perfect on my g73!
You need to cut every piece that you can



Look what I did
It a a little difficult

And this fan is loud like a hell xD
But I like it
I can relax because I know that my card is cooled

I think the space between your video card and the wifi card is a tad bit bigger. I had it like yours and it still will not fit. I'm trimming down the fins. It's getting there.

I mutilated the fan, I just wasted 4 hours I'm so pist

 

Bigger? I don't think so
It's the same size!

I'll need to order a new fan and try again. This one is beyond use.

 

Better luck next time
You will have another problem
When you close the notebook
I used a small piece of eraser and glued it next to the fan aboove the wifi slot
To avoid contatac between the fan and the back cover
Keeping the hard work!

 

Hello friend ....
remember that you have only applied small copper heatsinks on Vrms ...
It certainly will overheat very .....
I applied the aluminum bracket with copper heatsinks, all this was not enough, the Vrms were very hot .....
I made ​​a small change in the aspiration of the air, I created a duct air sucked by the fan to cool only the copper heatsinks ... it is as if there was a fan ....
the system worked, the copper heatsinks are cold ...

Princeblack is right! The VRMs diet very hot!
I put a fan and force the air to pass through the coopers
So princeblack where is your vbios?

Sorry Claiton you're right .... Unfortunately I'm moving house so I have little time ....
I was just checking Dropbox ... I am creating a accaunt ...
soon I put it in the net: D ... I'm sorry: D ....
to Claiton but for the HDMI?
The monitor works .... no audio
It may be a driver issue? I use the Catalyst 12.10 .... or a problem of VBIOS?

 

I tried it and no sound!
This is a problem with the clevo cards
The clevos 69xx don't have audio through hdmi too
With the dell vbios
Only the dell 69xx have no issues with hdmi, sound+video
So I think its happen with the 7970
Also my temps are a bit higher because my VRMs are getting hot the air that go into the notebook
In BF 3 I get 75C
And before was 72~73

Do not worry about the temperature is not very high ..
the important thing is that your fan is not at the maximum rotation ....
I am firm on 3600 RPM 72 ° C

here put my VBIOS with 900MHz GPU and 1250MHz RAM

https://www.dropbox.com/s/96xyvw87fs6muo0/7970M Clevo 900-1250.rom?m

 

how'd you get 900/1250 vbios? were you able to mod the stock one or something?

 

DO YOU WANNA OC? OK LETS DO IT

Enable Higher Clock Limits With -xcl + .dlls (not Unofficial Method) - Guru3D.com Forums

 

I can oc my card but now it is hotter than before in stock
but when you do de oc the temps are +1 or +2 C
My BF3 now is 80 in stock and 81 at 930/1400

 

I carnt overclock with software at all I have even tried rebooting my g73 to see if it was a software conflict but issue still remains
But I can say that the vbios @900mhz/1250mhz posted by blackprince works 100% but the memory dose not downclock when it isn't loaded it stays at 1250mhz also the issue with the gpu usage isn't as bad with is bios.

You would think that the GPU usage would be lower due to the higher clocks and the GPU having more graphical horse power !

@blackprice where did u get the bios did u edit it ? I would like 1 with 900/1300 and 1s going up in intervals of 25mhz on GPU and memory this would be useful

 

I my first time it didnt work to but after downloaded the newest version of afterburner I could overclock my card
now i am with 930/1400 stable
with 940 i hardly ever have issues
About my temps was hot because the room temp
So i live in brasil and here is verrrry Hot
I tested it in a room with AR
and now i in a normal room

 

Boys the new Sager is here. I'm in love..... but I'll never forget you....

:-D

 

U better not forget us eneyway I got 6789 3dmark 11 score !!! I have been tinkering I think I could brake that magic 7000 boys

just need black prince to tell me where he got that bios n if he modded it ?

If so how please respond I wana brake 7000 alienware heads ant even broke it with a single card yet would be nice if a nice OLD G73 did first. That would be funny

CUBAN what's the 3dmark11 score on that thing ?

 

Amazing score Rob
My best is 5620
My 720qm isnt enough for the 7970
But next year I will buy one 920xm
If anyone knows a person who is interested to sell it
I'll appreciate it

 

there is a few on ebay intel 920xm in CPUs, Processors | eBay

 

I have some good news for u I know some 1 that has a Sony viao that's got a smashed screen n it has a i7 940xm in it ! I was going to buy the laptop n fix it as I can get a screen for £79.99 and I have got an i7 720qm in a box that I could put in it and. I could sell the i7 940xm. He wants 300 for the laptop if I can get the laptop I will sell uthe CPU for £150 it's oem I can then put the 720qm in my Sony viao and sell it for 500 as its like New no scratches

 

That is great!!
Could you send it wordwide? I live in brasil !!
And it is a good price!
Did you put another clevo vbios on your card to overclock it?

Edit
Is it about 235 dollars?

 

mmm 940xm sounds tasty, im dirt poor though.

 

What's the difference between the 920 and 940?
What the maximum clock that I can run one 920xm?

 

I believe they they are virtually the same. the 940 is only slightly faster running at stock. if your able to overclock than a 920 would be the cheaper better choice.
it was one of the those things where 1 super fast chip was say.. 500 brand new. and the next model was 1000 with little difference.

 

That's not 100% correct lol the 940xm has a slightly higher voltage so it allows for better overclocking lol well mine has lol

 

but with the price difference/performance i dont think its worth it for a chip thats 3 years old

 

Lmao u carnt even get an 920xm es for that price thy still retail at 200+ GBP and take it from me there ant much performance difference between the new processor and the 940xm it will be good for gaming for about another 5+ years yet

 

im deciding what my next upgrade for my laptop should be... screen, memory, or cpu.... anyone know if there's a way to tweak memory timings or memory voltage on our g73s?

 

mems are subjective of use, if gaming... 8gb is still giving me no worries ( unless you want to render while gaming )
screens, matte full hd would be fine i guess, but still my old and original g73 glossy screen shows no signs of damages

cpu.. a good oc on a 920/940 would make you match or even surpass a 2630qm

throttlestop + the xm's will make the g73's run like beasts

 

Thaiphoon burner should be able to modify your ram timings, but it will be permanently so be very careful.

 

Checking back in boys. I'm loving the new Sager except when u composite it in weight to the Asus. I'm in the Dallas airport now and this thing I'm a slappa Jedi mind trick is heavy!

Not much activity since I've been gone, took a trip to Texas for 7 days

Anyways quicky update, added more thermal adhesive, anywhere you see copper there is thermal adhesive. I also added copper to other areas that did not have cooling. Since I've done this, the system has not blued screen in League Of Legends (not a very graphically intensive game).

The area I marked are areas that does not yet have thermal adhesive. I may give up on the fan idea if this fixes my issue. Also, I thought about expanding the cooling by adding aluminum wings to the heat pipe and also on the copper that I added to improve cooling. Thought of using a northbridge heatsink fins for this.



Anyone know why my screens shakes up and down when I overclock it? Did the same thing when I would OC my 5870m

 

The price you pay for proper modularity and cooling the new beastly cards unfortunately.

 

Oh it's worth it, believe me!

 

Oh a properly tweaked 7970M or 680M with an I7 can produce some very nice results.

 

My system with a fan is working very great! Ive never had a BSOD even with overclock to 930/1400
In my picture that I posted
All my VRMs are covered
I used super glue to put all five coopers together
And used Thermal pad between the VRMs and the coopers
So the heat is shared with the all coopers and a fan blowing air through them
The area nexto de card, where is the rams, are a hotter than before because the hot air is coming from the coopers but it nothing to worry about!


About the overclock I had it once with my 5870 too
But after change something
I dont remember now
If was the driver or the vbios
It disappeared

So good luck

Interesting choice of super glue, a thermal adhesive might give better thermal transfer to even the heat dissipation across the copper heatsinks.

 

I personally would not have used super glue. Correct me if I am but logic would say the super glue would brittle and fall apart over time.

My problem with overclocking is that the screen stutters/moves up and down every few seconds. Won't do it while gaming though.

My main issue right now is that the system completely locks up when playing a highly graphical game for more then a few minutes into the game, system hard freezes with buzzing. Takes about 15 minutes to crash with Unigine and about 8 minutes for Battlefield 3.

I'm going to ad fins to the heatpipe, might help draw some heat away.

I'm tempted to just buy a laptop cooler.

I would replace the fan with this

http://www.newegg.com/Product/Product.aspx?Item=N82E16835345039

145cfm vs stock 115cfm

You think the USB will be able to power this fan?

I may also end up making extra holes underneath the laptop to provide better air from into the laptop itself.

I could try to put the little fan back in but quite honestly I spemt hours last time and I am tired of tinkering with this laptop.
We'll see...

 

Screen "tearing" in 2d is usually caused by a mismatch in memory clocks, you likely need to change the 2d memory clock to the overclocked setting.

You can either use MSI afterburner to unlock overdrive and create a profile to edit the 2d clocks or you can modify the bios.

 

I probably use Afterburner to fix it, I will look for the 2d settings.

So I finish adding the rest of the copper heatsinks with thermal adhesive but unfortunately the results are still the same to say the least. System hard freezes when I have a intensive 3d app running, Unigine crashes within 25 minutes. Temps on the system at full load is about 76''C. So it has to be the ic chips heating up.

Here is a picture of the finished work. I thought about glueing (with thermal adhesive) some more copper heatsinks on the side of some of the heatsinks to try and bring down the temps. But ultimately if I want to use this laptop for gaming (assuming I do not find a passive cooling solution) I need a laptop cooler, thought about a Antec 200 gaming laptop cooler. I'll just drill some holes to provide additional vents for air to get in.

 

i strongly suggest what princeblack has done. a big chunk of conductive metal above all vrms and putting individual heatsinks above it. better heat dissipation due to larger surface area + better looking

 

I think you need to put the fan!
My temps now, in a very hot room xD, are 82
And the laptop never shut down by his self
The problem with the fan is the hard work to put it and the noise
You can put a switch to turn of it when you aren't playing games
I made I big hole in the back cover because my coopers are higher than the space inside the g73
And the coopers that I used have better cooling than yours
They are bigger
Try to change it
And see how it will work!
Good luck!

Yes using a contact plate and then sticking heatsinks on that may introduce another thermal layer, but it helps dissipate the heat across a wider area and in the end tends to work better.

It's the same thing desktop users ran up against when cooling VRMs on GPU only water blocks.
