Yeah, yours is version/2, same with mine. It has "version/2" on the board. Since you are using AMD card, why not use modified 2.07? FYI: To convert version/2 to version/3(ish) is pretty simple. Simply removing that 1k resistor will do the work.

Quick update: I have a version/2 adapter. I removed that resistor and tested a GTX 1070 and a GTX 970, both successful. GTX 970 is pretty straight forward, install the card, boot into system, install the latest driver, disable GT 750M, bingo. GTX 1070 requires a little more effort as stated in this post before. My experience is to: 1. Remove all Nvidia drivers using DDU 2. Install the older driver (something like 36x.xx) 3. Install the latest driver but don't choose clean install. Hope it helps! And I want to say thanks to @High_Voltageand all the other guys to make this possible, great work!

Thank you for the explanation! Will try it soon.

Thank you very much man! I'm reading through that long long post. I think mine is version2. So the only difference between version2 and version3 is that resistor from 1k->10k? And by removing the resistor or changing the resistor with higher value, the purpose is to cut that signal?

Hi @High_Voltage, first thank you guys for the amazing work!!! I got an adapter long time ago from gerald, but as I see in this post, there exists different versions of adapter? Does this BIOS works with all versions? Much thanks!

@TeslaI'm still confused about PCIe3.0. I'm using Y500 with GT750M, I7-3630QM,chipset HM76. I found that HM76 supports PCIe2.0 only(https://www-ssl.intel.com/content/www/us/en/intelligent-systems/chief-river/core-hm76-ibd.html?wapkw=hm76) but my cpu supports PCIe3.0(http://ark.intel.com/products/71459/Intel-Core-i7-3630QM-Processor-6M-Cache-up-to-3_40-GHz) Then I checked my GT750m: If graphics go directly to cpu then why 750m works in PCIe2.0x8? (According to NVIDIA, GT750M does support PCIe3.0)

I'm wondering whether this adapter can be used on Y500?

@gerald How can i buy the adapter? the ebay link seems not working

Hi Tesla ! Here's from China. I've uploaded this bios file to dropbox https://www.dropbox.com/s/a0b5g5p5b0b5fh4/y510p1.05.rar?dl=0 (i've bind 4 part file into one) Hope this helps u test the device. I'm a Y500 user and some Chinese Y500 users are keeping a close watch on this post. Good Luck! Amazing!!!!! Any possibility if I can buy this in China? Hoping more information! PS: My English is poor, hope clear
