Re: New y510p sli card not detected

I would reccomend this, yes; send the laptop with the card in, I've seen reports of people having sent only one and having the same issue after.

There are potentially at least 2 issues here.  John1107 probably has an issue attributed to the Windows 8.1 update which could apply to multiple models with second video card options.  Here is a link to the official article on the Lenovo support site.

 

The second issue was that some GT750M5P graphic cards sold as options were not the same version as those shipped with the system when the system was ordered with a second adapter from the factory.

 

If you purchased the second card as an option from Lenovo and it did not work, and you still have a non-working system, please contact service.  Service may be able to address this problem several ways, one way being to exchange the card under warranty.  There is a tip for service on this to help them with version and part numbers.

 

The BIOS also needs to be updated to version 3.05 or later.  This is available on the web.

 

Best regards,

 

Mark

I've been having a problem with my card not working for some time now, and was waiting for a solution to be posted.  However, My laptop is now out of warranty and I'm going to have to pay to replace faulty parts through no wrong doing of my own, is there anything else I can do?

If it is a new card and it never worked then you can probably ship everything back and get it fixed. If it came with the laptop and it stopped working after you upgraded to Win 8.1 then there is a simple video card bios flash that will fix it. If neither of these match your problem them you might be out of luck and have to pay for the repair.

Hey all, I too have this problem. I was hoping for a fix at home like bios upgrade, but unfortunately that doesn't seem to be the case. I bought the laptop without an original sli configuration and later bought an sli graphics card. I bought the GT755m5. Tried installing it and now it doesn't work. (Has an error saying the slave is not compatible from the start".Tech support has been a nightmare because the cards I have don't match. Tech support says if the cards match then it will work. However, after reading on these forums I know that not to be the case. The "beauty" of it all is I can no longer purchase the card that came with my laptop the GT750m5 because after having to call sales they don't have it. So tech support says that I have the wrong card and will not continue with me until I have the cards that match. I have been on the phone for multiple hours with no solution and it's terrible. This turns me off to Lenovo as a company. It seems like at one point they were trying to help the customer with this problem and now they will just keep transferring you to every possible department. I have now spoken to tech support, sales, post sales, warranty, and was even referred to CDW to see if they had the "correct" graphics card. I have a case number, but it looks like I'm up the creek and will not be able to get my graphics card working because they have moved on from this problem. Sorry if this post is long, but I am frustrated and realize that I'm probably just venting at this point. My advice to others is if you have this problem don't continue to wait because a self solution will not be available and it seems like tech support will now just give you the run around because they have moved on to newer laptops.

Um no, you need matching cards (2x750 or 2x 755) for SLI to work. Where did you read they would work together? The only way to get non-matching cards to work is either by physically modifiying the ultrabay card or using a hacked bios and hacked drivers (which may or may not work). Either way that has nothing to do with this thread and support can't help you. This thread is for people with matching cards and the second card doesn't even show up (no error messages, nothing).

You should try to return your wrong card to whoever you bought it from and get the "GT750m5" card on ebay. There are more than one, some cheaper than others. That's the only way.

After you get the right card, call Lenovo again to have them service your laptop so that the card can become usable.

Re: New y510p sli card not detected

When I purchased the card I chatted with one of the sales reps online and was assured that it was the right one for my laptop. I mentioned the card difference and was told both would work. I even saved the chat conversations. So, I bought the gt755m from the lenovo website. When I called to exchange it, they implied I could return the card, but there is no gt750m to buy from them. I can only imagine the conversations with tech support if I try a card not from them. Also, I thought it fit the description of the thread because I had a new card labeled for the y510p that didn't work. Although, I guess it was technically detected. So my apologies there.

I also bought a wrong card from Lenovo but immediately returned it to them. Then I bought the right card on ebay. The right card itself failed to get recognized by the laptop, so I reported to Lenovo technical support and had my laptop serviced. Problem solved. If you hold on to your wrong card, you will get nothing. The technical support actually doesn't care where you buy your card. As long as it is the right card, they have to honor it (because it is their product carrying a warranty on it!!!) and have things fixed. If you get the wrong card from Lenovo but refuse to return it and buy the right one available elsewhere, no one on earth can help you.

Sorry to hear about that but unfortunately you were miss-informed (you aren't the frist one either). Techsupport knows NOTHING about SLI and ultrabay accessories and they cannot be trusted for information. They use to tell people that when running SLI there was no way of knowing you have a second card installed without going into DX and looking at your total graphics ram (which isn't true) and the second card would not show up in your device manager (Again, not true) and the Nivida control panel has nothing do with SLI (again, not true). They also denied that there was a problem with dual 750 cards for over 6 months.

 

Unfortunately there is no way you can get those two cards to work together in any way without resorting to physical modification or using a hacked bios/drivers which is flakey at best.
