Reddit reviews EXACT B156HAN01.2 New Screen Replacement with Free Return & Same Day shipping, 2 Year Warranty. Matte IPS 1920x1080 Full HD Laptop LED LCD Display

I have a Lenovo Y50 and have overclocked the GPU for the last year. The Y50 in particular has pretty robust cooling and a modest video card, so you can get away with an overclock.

However, I wouldn't recommend overclocking much. I have +100mhz core and +300mhz memory, and that's one of the higher overclocks I've seen on a Lenovo Y50. It typically gets me +5 fps in games. Nothing miraculous, but certainly welcome. I have Samsung-manufactured VRAM in my Y50, which is the most stable apparently. You may not want to shoot for a 300mhz memory overclock, maybe 200mhz or 250mhz.

When you overclock, don't raise the voltage. That'll increase heat too much and risk damaging the GPU. Just do what you can on default voltage.

I've run my laptop this way in games for a year, and it's stable, and temps are safe.

However, I'll point out that the Lenovo Y50 has a godawful TN panel screen; one of the worst I've seen. If you can perfectly follow a Youtube tutorial, I think replacing your screen with an IPS panel will help your visuals a lot more than overclocking. I replaced my Lenovo Y50 screen with an LG IPS panel and it was an awesome decision.

Also worth noting, the Lenovo Y50's default RAM is in a 1x8GB single-channel configuration. Switching to 2x4GB or 2x8GB in dual channel by replacing your RAM would noticeably improve performance and system responsiveness. Even though RAM doesn't usually affect performance much provided it's dual-channel, single-channel laptop RAM is just too slow and actually does make a difference.

Edit: A great compatible Lenovo Y50 screen.

It's about $70-$100 depending on the panel you want. You simply pop off the surrounding lid from the corners and remove 4 screws and an adapter and pull the screen out, and replace it with the one you order. I ordered this off Amazon, I'll let you know if I end up liking it
