Windows 7: Mixing RAM memory with different size and brand

Mixing RAM memory with different size and brand

Hi, I am willing to buy additional memory for my PC. The PC specs are below. Currently I have 3x2GB 1333 and my question is can I add an additional 4GB in the fourth slot so it goes like 2GB 2GB 2GB 4GB? All 4 modules have the same timings and frequency but different size and brand. Will that work in full capacity?

MB: Foxconn P67A-S
CPU: Intel i5 2500
RAM: 6GB 1333
HDD: Western Digital 1TB WD10EARS

Not in full capacity no, for starters your RAM won't be running in dual channel. It's always advisable to buy RAM in kits (2x2GB, 2x4GB, 4x4GB etc) as they're manufactured to work together perfectly. You can always try adding a 4GB stick but my advice would be just to buy a whole new kit, mismatched RAM can cuase issues.

I have a new M7 64 bit machine with 8GB of memory installed, specifically Samsung 4GB DDR3-1333 PC3-10600 memory (times 2) and I was wanting to add identical memory sold by Micro Center for half the price. Would this be problematic? Should I pay twice the price for Samsung memory?
