Match RAM or buy 2x8gb?

Hi all,

Apologies if this has been asked before but the search functionality always returns zero results for anything I search for.

I've just bought an E6520 and it came with 1x4gb Hynix DDR3-1333 (667mhz). Will I be OK to match the ram with another 4gb DDR3-1333 of whichever brand, or should I go for something like a matched pair of Corsair Vengeance Performance Corsair Memory 8GB Vengeance Performance DDR3 SO-DIMM 1600 MHz 9 Dual Channel Laptop - CMSX8GX3M2A1600C9 - Scan.co.uk or similar?

I want to get the best performance out of the machine, but I don't want to pay the extra if I am not going to see a difference between 1333 and 1600.

I will be going down the eGPU route with either a GTX 460 or 560 Ti, if that changes things at all.

Thanks,

 

The difference between non-matched pair and matched pair, is even less than the difference between 1333 and 1600.

 

Typo in thread title, should have been 2x4gb

OK thanks,

In that case, I'm just going to grab this:

Hynix 4GB DDR3 SO-DIMM PC3-10600 (1333) Single Channel Laptop Memory - HMT351S6BFR8C-H9N0 - Scan.co.uk
