MXM Standard 3.1 is the new one (Up from 3.0)

...so we heard the birds singing.

Resellers, be honest what`s going on?

 

Thanks for the thread =) (He Made this so I could post the whole story)

Ok so MXM 3.1 has been released as of last night, so now that its a published standard we can post about it.


MXM 3.1 adds the following things:

- Support for PCI Express 3.0
- Extra Debugging (Mostly to support 3.0)

Here's also what we know, that mostly this is a validation standard change, there are a few NEW pins used on the connector (They were previously "Reserved") so there is not a physical connector change. 3.0 Cards WILL work in 3.1 slots, and 3.1 Cards WILL work in 3.0 slots. The only change is that if its a 3.1 card it won't work at PCI Express 3.0 speeds (Only 2.0 or 1.0)

Now the real question.. Are the P270, and the EM series 3.0 or 3.1 Slots? We don't know yet, as we don't have any 3.1 cards to test them with, and Clevo has been tight lipped about it. I can tell you that the standard has been privatly released for less than 30 days. So the chances of them doing a whole new motherboard spin to support 3.1 (As there is some addition stuff on the motherboard that has to be added to support PCIe 3.0 speeds) are pretty low at the moment. But we'll see once we get new generation cards (Hi AMD) that support PCIe 3.0

We will be happy to answer any other questions in this thread as best as we can.

 

So long upgrade to my P150HM

 

You can still upgrade, this MXM change is BACKWARD and FORWARD compatible. So lets say the AMD 7000 series (Not saying it is) is 3.1, it'll work just fine in your machine, it just won't work at PCIe 3.0 speeds, which isn't a huge deal.

 

phsew, what a relief! i was at first shocked to see this thread pop up but all is good now, especially since there are no real perf advantages yet by using PCIExpress 3.0 as opposed to 2.0 P150HM GPU update still up!

cheers

 

Intel doesn't even have PCIe 3.0 mobile mobo for this year yet

 

How much watt will this standard support?

7970 is barely having any performance issues with PCI-e 2.0 x32 in high resolutions, there is no way any of the highest mobile GPUs will cross that boundry

 

YAYY!! pure music to my ears!! THANKS!! 680m here we come!!

 

Phew, thanks for clarification! Now to see what 7970/7990 has to offer.

 

agree, pcie 2.0 already very enough for hd6990/gtx590 oc.......so for a laptop vga to catch up hd6990/gtx590 oc, few years after

 

Great news to hear,
so we could survive more years. I dont think there will be a big diffrence between pcie-2 and pcie-3 .

 

the only problem will be the bios support for the cards.

 

cant we flash bios with an modified bios to work with that cards?

 

oh im sure some tecchy-freak member of this, our beloved forum will figure something out in case theres no official BIOS support for the new cards

 

nice) glad to hear it has full compatiility! anyways, it'll take a few more years to take a full advantage of pci-e 3.0 GPU's...

 

This is not the first time when we needed modified BIOS for our laptops. So far no one has shown interest to engage in such a project and I've been around here for some time.

Bottom line, don't count on it.

 

not cool, destroying my illusions like that haha
but oh well, lets wait, see and hope for the best then @BIOS support from Clevo

cheers

 

We are actualy succesfully using newer cards on older bioses which had no official support yet. There is a MXM module in the bios which takes care of stuff, will take a closer look at it when i find time...

 

Seeing that Clevo/Sager tested the 7970Ms with the HM series, I would like to believe that they will be awesome next year and do the same for the HD 8000M and EM series.

 

Hello

in hm77 Mobile Intel® HM77 Express Chipset

why there is PCI Express 3.0 Graphics ?

and why in ( notebookcheck.net )

im' seeing in front of Bus Interface PCI-E 3.0 x16 @ x16 3.0 ?

We can't utilize PCI-E 3.0 in p150em ?

how much performance will increase with pci-e 3.0 ?

Thank you

 

Shows PCI-E 3.0 x16 @ x16 3.0 on mine with GTX680M, it's already in the EMs. But idk about performance increase.

 

perf increase is pretty much none when comparing 2.0x16 with 3.0x16 on a desktop highend card ull get like 2% boost, if at all

 

There is no official support or Bios for the 680M in my P170HM but it still works, other than needing a modified inf for Drivers. Of course official support would be great but either way, there is always a chance it may still work.
