Memory upgrade - Help required

[jedynew]

Hi All,

I own gigabyte ga-ma785gmt-ud2h mobo / AMD Athlon II X4 620 processor 2.60 GHz with Transcend 2GB DDR3 1333 DIMM CL9 memory stick.

Now i would like to upgrade it to 10GB to run vmware images.

I am planning to purchase it from Flipkart. Please suggest what are the key things i need to consider while upgrading.

should i go for corsair or transcend ?
should i buy 1*8GB or go for pairs 2*4GB ? (4 slots available)
will my existing single 2GB effective after upgrade when it goes to 10GB ?
If i go for corsair with my existing Transcend, will it create issue ?

shall i consider the below models :

Corsair Vengeance DDR3 4 GB: Rs.2200

Best to get all the DRAM you want/need in a single package, no guarantees when mixing. 1333 in 2x4GB would be good with your rig

Thanks Tradesman1. I will go for 2X4GB either in Transcend or Corsair. Even looking at Gskill.

Sounds good! GSkill is my fav
