Retooling a Clevo W860CU chassis

Hello,

I'm trying to upgrade my laptop as best I can, though I'd be happy with just a better GPU. I have a GTX 285m. As far as I can tell, the best I can do is a 6970m, but that requires a load of sawing and drilling new holes and stuff which I'm not exactly confident about doing. If was to get a newer mobo, in order to upgrade to a better GPU, would I have a lot of trouble installing it? Is my chassis a standard size? Or am I opening a massive can of worms?

thanks

Jonathan

 

Much more massive can of worms than modifying the heatsink.

Why would you want to replace the motherboard? Its the heatsink thats the problem.

You could try to get a heatsink from a Clevo p150hm which supports the 6970m, but it will be expensive, and I really don't think it will fit.

Hmm... You might not have to do sawing and drilling. If I remember correctly, its the top part of the heatsink that is the problem, and luckily this part is made of much thinner copper.
You can probably cut it with a good pair of metal shears.

lol, I have to reiterate, since you actually said "retooling" the chassis... do you realize how much sawing and drilling that involves? I have modified a few acer chassis for use with motherboards that had a DVI and firewire port where the old one didn't, its really not easy.
Additionally these were multiple motherboard revisions of the same PCB shape, no your w860cu is NOT standardized, the entire motherboard is a 1 of a kind model, or maybe 2 with the USB 3.0 revision. No other clevo motherboard including the p150hm would have the slightest chance of being able to fit.

 

sorry to duplicate my other thread, but is there not anything else that will fit than my current 285m? i might just get another one of them...

 

The 5870m and 470m also fit your notebook (and heatsink) and will give you a nice performance boost.

The 5870m will be about 15-25% faster, while the 470m will be 30-50% faster. The 6970/6990m on the other hand will net you a performance increase around 100%, twice as fast as the 285m (which I originally had as well).

The 470m is a very capable overclocker, but I believe it is hard to find, and a 6970m might even be cheaper.

If you don't want to modify your heatsink I have a spare on which fits the 6970m/6990m. Send me a PM once your post count is over 10, if you're interested.

 

Thats not true, oan001, you need a different heatsink for the 285m, 5870m and 470m.

 

You can easily order the GTX 470M w/ W860CU heatsink, if you've given up on the 6970M.

 

Yes, I forgot to mention that. OP: You need to check which heatsink you have. There were basically two different heatsinks for the w860cu:
P/N: 6-31-w860n-023 - The first heatsink for 280m/285m
P/N: 6-31-w860n-061 - The second heatsink for 5870/460m/470m

So you would probably need a new heatsink (for the 5870/460/470) if you have the first revision.

EDIT:

I would not go with the 470m for that price, it's too much. You can probably get the 6970m with a modified heatsink from eurocom for cheaper.

 

I actually have 1 pair of 470Ms but I don't have the heatsink. They are just sealed on my desk. PM me if you want one for a reasonable price.

 

Cool, thanks for the help!
Patrck_744 do i have the capability/space to run both of those 470ms together?

 

The w860cu only supports one GPU.

I know for the 6970m to fit, the heatsink requires modification, but do I need a higher capacity psu to handle the 6970m + 820 processor?

Also, is anyone selling a modified heatsink?
