I have a notebook with Clevo W251EFQ/W270EFQ with single channel 4GB 1333MHz RAM and i7 2630QM 2GHZ cpu and Intel HD Graphics 3000 plus Geforce GT635M 1GB with 270, 540, 405 MHz clocks.

I want to add ram and according to crucial.com I can't upgrade my gpu. I don't do gaming much but really enjoy when I do. I usually use 2-3 browsers with many tabs and that often slows and rarely even freeezes it and browsers crash.

I don't want to spend excess for something that won't benefit much, so I looked at gamedebate and 8 GB RAM and my cpu both scores 9/10 so I now think adding one fast 4GB RAM is my best bet. It seems the mobo supports 1.35V RAMs because all rams listed for the laptop in crucial.com is 1.35V. Also RAMs up to 1866 MT/s speeds are listed at crucial.com

Can you suggest the best 4GB 1.35V RAM for this ?

For example I've found Kingston HyperX Black 4GB DDR3L 1600MHz CL9 Notebook Ram HX316LS9IB-4 is cheap enough but it says "HyperX Impact memory boasts the world's fastest SO-DIMM frequency - 2666MHz - to keep you ahead of the curve and level up your game." and I'm not sure my mobo supports that. I'm not sure I get it right, the site lists best KVR16S11S8/4
4GB 1Rx8 512M x 64-Bit PC3-12800 CL11 204-Pin SODIMM for Clevo 251EFQ:

I also couldn't find one 1866 MHz 4GB RAM listing yet. I also can find 4GB 1.35V 1600MHz Hynix RAM without package but unused at half the price of Kingston HyperX Black. Does RAM without package but unused sound good enough to you ? And would HyperX Black be seriously better ?

Please help, one small answer may be enough, thanks in advance
 
Your CPU has a memory controller with DDR3-1066/1333. Anything more than 1333 won´t improve anything.
Look at the timings too. CL9 is much better than CL11


Because your Laptop has freezing issues, clean it. Most likely it´s an overheating problem, which will persist if you just upgrade one component.
