X775 / X770 Disassemble Thermal Repaste

[niffcreature]

I've purchased the gtx 560m card you have in your laptop(s). It does not have an EEPROM, which means the vBIOS is embedded in your system BIOS. However, this doesn't mean you can't use other cards.

Glad to see toshiba using MXM! Why not try a 6970m?

If the vBIOS does not check then this would really help if ya got the bucks

Here's another for sale; FS: 1) Nvidia GeForce GTX 480M 2GB DDR5 MXM 3.0 type B

usnnavy's picture is a bit fuzzy but it looks like we have non standard MXM cards?

Here is another 560m card;

So my most recent project has been wrapped up (S&W M&P) and I'm honestly getting really tired of my screen. So currently I'm shopping for the perfect replacement to get the best bang out of our buck. Trying to get away from TN but my knowledge is so low, definitely a learning experience for me.

So, for example, can I change the 560m for a 670m or 7970m?

The only GPUs Qosmios will accept are those that are Toshiba made for that specific type of Qosmio.
For example: the x775 might be upgradable to the Toshiba GTX 670m from the Qosmio x870; however only the Toshiba version of the GTX 670m will work [can't use ASUS/Dell/MSI/etc..]

If the x870 doesn't come with a AMD 7970m, then you can't upgrade to it. Not to mention, Toshiba has NEVER used AMD as their GPU solution.


tl;dr, GTX 670m: maybe ; AMD 7970m: no

[rofay10]

So a 670m buyed in ebay or amazon won't work to?

Most likely no.

Roberts, I swapped my screen out with a Dell XPS 17.3" 1080p screen, that looks 10x better than the crap that came on the laptop. It's glossy, not matte, not sure what you're looking for but I can find the link to the one I bought if you're interested. It was around 80$ but this was almost a year ago.

As for the thermal repaste, im not noticing any better temps with arctic silver, it still gets almost to 90C when gaming, and the gpu gets into 80's. I'm gonna look for some of those heatsinks and try what you did.

Edit: I have an x775 Q7272

Oh, and where did you get those little copper plates you stuck on there?

Looking at that picture again and according to the people I've been speaking to, i.e. Toshiba Tech Specialists, I have been told that the X770/X775 model does in fact have have an MXM 3.0B slot.

I'd also like to state that it DOES recognize the 570M and 580M. However, due to the issue related to heat, the laptop doesn't react well if the 570M is paired up with anything greater than a "Sandy Bridge" Core i5 CPU.

These are the two i5 choices that are best suited for use with the 570M and will not bottleneck the graphics card:

The Core i5-2450M (2.5GHz Stock; 2.8GHz 2c/4t --- 3.1GHz 1c/2t |Max Turbo Values|)
The Core i5-2540M (2.6GHz Stock; 3.1GHz 2c/4t --- 3.3GHz 1c/2t |Max Turbo Values|)

These CPUs are 35w total combining a 25w CPU with a 10w iGPU, the HD3000. The i7s are 35w CPUs and run too hot, so nothing beyond the second listed CPU is advised. Even the dual core i7 models out there are known to run a bit warmer than the two Core i5 processors listed here.

The 570M is recognized by the BIOS, tested by one of the specialists whom I spoke with after he got off work. He says the 570M he used was a standard Clevo card from the Ebay user 'upgradeyourlaptop', I.E. Eurocom. He ran a few tests and found that the TIM used matters a lot in this case because your temperatures will be rather high. Any cooling mods like the ones listed here are advised if they'll work without much of an issue. I cannot post any pictures of this since I've only to take his word from it, however... it's definitely nice to know that there's someone who has attempted it and had some success.

As far as temperatures go, he used the Qosmio X775-Q7170 laptop model, as it's seen on Newegg, and reported these GPU and CPU temps from two simultaneous 3DMark Vantage runs:

Run #1
CPU: 94*C (hottest core)
GPU: 90*C

Run #2
CPU: 97*C (hottest core)
GPU: 95*C

(The GPU scored ~11,000 in performance mode, not sure if that's a bottleneck or temperature related but it looks right. )

He used Arctic Silver 5 and it hadn't cured yet, so that mattered a bit here I think, AND without any notebook cooler. ~Temperatures between a batch of cured and uncured Arctic Silver 5 can vary by as much as 3-5*C!~ This was also done with the 1.10v BIOS, that was recommended by me, to keep it from throttling. (He says "thank you" btw and, since I learned about it from here, I figured you all deserved that much credit. ^_^)

Again I hate not having any pictures to prove this, however he said it works fine, despite running really really hot even for just two Vantage runs, and I was on speakerphone with him while he did the tests and such if that matters.

I hope this gives you all a bit of insight in the end! If someone wants to test it, I'll help out with the cost of the 570M so they aren't entirely deadened by the horrid price. (They run around $350 + shipping. )



Thanks for reading!

Great info Glid !!!

Glad to hear I was wrong! I think GPU upgradability [even if unofficial] should be the norm for gaming laptops.
If the upgradability is dependent on heat, I wonder if the new 28nm GPUs will fare better... [supposedly they emit considerably less heat than current 40 nm GPUs - GTX 560m, 570m, 580m are 40 nm].
