G73SW-BST6 Repaste with pics of GPU

So I re-pasted with as5 and temps dropped slightly as one would assume. The g73sw runs so cool to begin with I didn't really need to re-paste it, but 1. I'm a geek 2. I have thermal paste laying around and 3. I was bored. So I re-pasted it anyway.

One of the questions I wanted answered more than doing the re-paste was "What are the physical differences between the 460m 1gig and 460m 1.5 gig" I found some interesting things out like the unsoldered chips and the heat-sink looks to be fitted for the 460m 1.5gig. Seeing that the heat-sink is probably the same answered my question as to whether I would need to order a heat-sink and gpu if I ever upgraded to the 1.5 version. So here's the pics...

The cpu and cpu heat-sink(not a terrible job on asus part)



Next is the gpu.


Ive circled where the missing memory would be located, its pretty obvious. I didn't pull the card completely out, so I could not verify the memory layout on the bottom


Finally the heatsink. Notice the circled area. If I'm not mistaken this is where the additional chips from the 460m 1.5 would be cooled. So I'm pretty sure the heatsink is the same for both and there are no physical changes in dimensions form the 460m 1gig and the 460m 1.5gig. Upgrading to one should work easily.

 

my G73SW is G73SW-BT. and by accident they give me 1GB gtx 460m. i complain to ASUS, and they change it to 1,5 GB

 

Very interesting pictures!

So the 1gb version of the 460M GTX is literally just a modified 192bit version.

This just does not make sense how that is saving BB money?!!

 

i agree with that. two chips can't hardly make that much of a difference in the margins.

 

i own gtx 460m1gb, and now mine is gtx460m 1,5gb(replace by ASUS). 2chips missing will blew 600-700 points in 3dmark 06.Lol
but what is really interesting is, i remember when i play with gtx 460m 1GB overclock i can not do Extreme in all settings. and with 1,5gb gtx 460m overclocked. i can play in everything in Extreme with smooth gameplay. hmmmm seems like syntethic benchmark is not too promising.

 

The biggest difference is bandwidth (20gb/s) more in the 192bit version so when running benchmarks at 720p etc they will not utilise as much bandwidth but crysis 2 which is very heavy on the GPU will happily consume as much as is available at 900p/1080p.

 

Yea thats what I first thought. The only thing I could think of is that Asus, for some reason, made a few thousand 460m with only 1 gig.

 

You want my theory?

Its pretty obvious how BestBuy have made their money. Asus would easily have had a ton of Reverse MXM GPU's which cannot be resold.

My bet is they where bound to have rejects with bad VRAM modules.

How easy would it be to modify the Bus and remove VRAM modules? The faulty ones I would bet, then put them through the Binning process.

Sell them to BB for cheap.

Its pretty simple really.

 

Nice pics!

Can't find my pics of the back of the JW 460m (1.5GB), but as far as I remember it has 8 vram modules on the back too, so there must be two modules less on the back of the 1GB version too.

The card and the heatsink are identical as far as I can tell. When I took a closer look at the fit of the heatsink on the GPU in the JW, I realized that the heatsink didn't fit perfectly, the coils were to high for the heatsink which resulted in a quite big gap between the upper vram modules and the heatsink. After some modding the fit was perfect, and the temp dropped some more degrees, since it also reduced the gap between die and heatsink.

Would be interesting if this applies to every 460m heatsink or if this simply was a bit an unlucky fit in the system I worked with.

 

My GTX 460m 1 gig overclocks like a champ im currently at 800,1600,1500 and GPU-Z claims 48 Gb/s. thats much better than the 40 i had to start with. when i maxed out the clocks on everything it went up to 53 Gb/s i think but wouldnt run benchmarks lol. at least im getting half decent performance now. and it runs very cool never gets above 60-65 C usually.

 

Yea, I noticed the same thing about mine. Part of the heatsink didn't sit flesh on the memory modules, if I recall is was to the upper left, opposite of the spring loaded screw corner.

 

sorry for my stupid question but how do to overclock graphics card?

 

You can use Nvidia Inspector, MSI Afterburner, or EVGA Precision to OC the gpu. So far my favorite, is MSI Afterburner, was having a few lockup problems with Inspector after installing the latest driver. But, all 3 should get the job done well.

 

after overclocking I will be able to run games in higher fps ?

 

You can achieve higher FPS by overclocking the core/shader and more bandwidth overclocking the memory. Overclocking each part will provide different benefits however by overclocking both together you will get a performance boost.

Dont expect miracles and every chip is different so what you achieve before crashing/artifacting/locking up might be different to what someone else can achieve.

Overclocking although is only a minor risk to damage does raise the temperature of the GPU so if you are already pushing higher temps (80's,90's) keep an eye on the increase. Its not common that a GPU fries from overclocking on a notebook because of the limits but its not unheard of when the VRAM or Chip is not pasted correctly or has poor conductivity to the heatsink.

 

That's interesting. In this case it's a poor design by Asus... but it doesn't really matter since the card runs cool enough.
But you can easily mod the heatsink with a metal file and make it fit perfectly.

 

i try MSI Afterburner and i don't see any difference when playing games
I just reset and delete from my laptop

 

You have to run FRAPS while playing your games. Every time you OC see how much fps is added.

If you play the Witcher 2, here you will see how the 192-bit 460M struggles on stock clock on pure Medium setting. You'll need to OC to atleast 800+..

Old games (2008-2009) won't require too much OC'ing of the 460M. This November, Elder scrolls Skyrim will come out, this will require OC'ing of the 192-bit 460M most likely /for sure ..

Nvidia Inspector and Afterburner are good tools, I use both..

I'm playing Dragon Age Origins again right now in 1920x1080p (old game but the best game EVER!) and I have it set to the highest graphic setting with 4X / 8X anti-aliasing and I have the GPU OC'ed to 750 / 775 Mhz for 35, 40-60 fps).

After experiencing the 1920 x 1080 resolution for almost 3 months now, I can never go back to anything lower. This resolution is amazing, but requires more from the GPU. I also really like how the glossy screen makes the game look more awesome, only glossy screen for games for me from now on..

 

what are these ''white stuff'' on the memories, are they thermal pastes ? should i paste it if i wanted to repaste my gtx460m ? please answer as i am repasting the gpu now and i left it because i dont know what to do with it. ...

 

They are thermal pads and no I would not recommend replacing them with thermal compound because the clearance to the heatsink might require the extra thickness of the pad.

If they are not damaged or stretched you can just reuse them and they will continue to work fine I have reused mine several times but most tech's will recommend you replace them.

 

what should i do now then ? i am looking on it at this exact moment, and i really need to go to sleep and finish everything, i already done with the cpu, but the gpu.....

btw there still the thin on the memory and the heatsink, should i just leave both ?

i saw some pictures for the new asus laptops, and somone was applying thermal compund on it, btw i am using arctic silver 5

please answer fast , thanks

 

I explained why not to on the other page if you have a Vram module not conducting with the heatsink you could have problems and they normally do not get hot enough to require thermal compound so the pads are fine.

As long as the pads have not been moved leave them covering the VRAM and any other sections they may be applied to. Repaste the chip only IMO and then reseat the heatsink and screw it back on 1-2-3-4.

I just noticed your original post was not answered my apologies I missed this or I would have, Arctic silver is fine to use and yes go with the pea method a 3mm blob amount is fine.
