I got my lenovo y570 in November last year. I've made a plethora of trips to the service center right from week1 of getting this laptop - the problem being, bluescreen on windows7.
So far, the service center people have tried the following in chronological order:
So, last week when I got my second RAM, replaced as well, I came back home and in 2 mins. I see the BSOD.
I've managed to work on this laptop and not leave this laptop at service centers because, it just works fine with 4GB ram in one slot. The moment you add another 4GB RAM and start using windows, it BSODS every 30mins.. and very randomly.
So, at this point the technicians are kind of clueless as well. I am beginning to think its either of the two issues:
1) Processor Issue? (which doesn't make sense to me)
2) BIOS version issue - My current version is 47CN34WW(v2.12), 6/21/2012. I am reading that 2.10 version sits well y570. So, I am guessing that when they sold this laptop to me (refurb), they upgraded to the wrong bios version?
I would like to try to downgrade the BIOS, if that is possible, and see if that helps solve this 8GB RAM issue.
What do you guys recommend? How do I downgrade it?

As for the BIOS, use version 2.10 which is the one I'm using for my Y470 since I've never had a problem with the NVIDIA graphics switching, BSODs, etc.
As for the BSODs, update ALL of the drivers and make sure Windows is up to date. On my 550m, I haven't updated my NVIDIA to the latest and still using 314.07 as I found it to be stable and never had BSODs.

Hi, thanks for your reply.
This laptop BSODS with a fresh copy of windows (one key recovered) and with no drivers installed. If you remove a 4GB RAM out of the two, then it starts working without issues. I do not think it has to do with drivers any more - it can't just fail with a brand new copy of windows and 8GB of RAM.

Have you tried with aftermarket (not a replacement) DDR3-1333 MHz 8 GB kit from Corsair, Crucial, Kingston etc.? It might be the problem lies on the brand of the RAM module (OEM RAM is incompatible?). But before you try another kit, you can test your RAM using Memtest. Run it for 7 passes for optimum diagnosis. If there are no errors, try the the aftermarket kit and see if the laptop can recognize the 8 GB on v. 2.12 or if BSODs happen with v. 2.10.

No, I haven't tried aftermarket. I did run memtest and prime95 on both RAMs individually and they showed no errors. When I test both RAMs (8GB at same time) prime95 gives me all sorts of errors! Right now OEM RAM that my laptop has is Samsung - I want to try aftermarket as last resort, because, I dont want to end up with 8GB of RAM that I cannot use anywhere else (This is the only laptop I have). Do you think I should just get one single 8GB RAM instead of 2 4GBs next time (if I ever get aftermarket)? Would it make any difference?

If you get a single 8 GB RAM module, it would be slower than 2 x 4 GB kit since the 8 GB will run in single channel mode as opposed to dual channel mode from the pair. I doubt you'll see a performance difference in real world usage if you're in single channel mode. I recommend though to try the 2 x 4 GB aftermarket one as a last resort as opposed to the single 8 GB RAM. If you like, you can even try 16 GB kit which I know that Y470/Y570 can handle.
If the aftermarket one is stable, you can sell your old RAM to ebay or something to get some value out of the it.
