Pictures of disassembled Y500 Ultrabay GPU

Recommended Posts

For educational purposes only. The Y500 Ultrabay GPU will not fit in the Y400 and vice-versa because the cases are different dimensions.

Very interesting, thanks for posting this. Have you tried one of @svl7 modded vbios for overclocking? I think he might have a GT 650M one.

Yeah he's got one for the most recent BIOS revision on the Lenovo IdeaPad Y500. We're still trying to figure out how to get the vBIOS on the second GPU to flash so that overclocking in SLI works. That was the reason I took apart my GPU and shot these photos in the first place.

Nice work! Cool to see this thing+ :D

Seems like my assumption was correct, I guess the part I marked holds the vbios, can you tell me the number just to be sure?

EDIT: Nevermind, just saw your PM.

I am curious if they can offer upgraded graphics cards for the ultrabay in the future and use that card as the primary and disable the internal 650m. I'd love to drop a GTX 680M in mine.

Not a chance. Do you see the size and shape of the PCB on that thing? And it's not even using MXM. It's impossible to disable the internal GPU as well.

Can you please also try to disassemble the HDD module ? It would be great!

Don't have it.

It *might* be possible to use a 750M provided they don't make major changes to the body design of the Ultrabay in the latest Y500. It is possible to use one GPU from the Nvidia Control panel (i.e. install a theoretical 750M then switch to it as the primary GPU for games) that being said, a 750M may not have the performance of a SLI 650M set-up. It will most likely be around a 660M's performance.

Damn small card... Hmm i have a problem with my y500 that rly dosent bother me that mutch but it may lower the second hand value! My ultrabay is stuck i have followed all the instructions on how to remove it but still its not moving. Someone have experienced the same issue ?

I think Lenovo has already replaced 650m with 750m in newer y500 models. A single 750M scores p2600 on 3dmark11.

No there is no any design changes of new ultrabay..and definitely dont have the speeds of 650m sli...and Do you think gt660m is faster than gt750m

No its not..gt 750m is revised and tweaked version of gt660 so u can expect more power than gt660 in some sites people states that gt750m with faster gddr5 memory is on par with gt 670m..

Y500 GT750m SLI is now available on the Lenovo site. And here I sit having just opened my new Y500...oh well.

Nice maybe we can do some soldering in the end :)

Lol, that's sounds adventurous...

I was talking to a freind so this may not be reliable but he said that SATA and pcie were pretty close to the samething he said that it would not take very much to change the two.

And to William, have you seen the price of the 650M ultra bay I bought mine with 2 but looked at getting one there like $300+ so I could only guess at what a 680M would cost.

Picture of the 750m ultra bay redid the thermal paste..

Did the repaste help? What is your max Ultrabay temperature now?

Would it be possible to mod a consumer GT750m card to be able to connect in the Ultrabay slot? Not even necessarily fit into it, but just so the connection is there?

There is a tiny little lock tab under the battery bay that you have to unlock before you use the little slider and pull it out....took me a minute to find it as well.
