Hi All,

Since DDR3 prices have dropped I have been thinking of upgrading to 8GB from the 4GB I am currently using.
I have 2x2GB Corsair DDR3 1600MHz CL9 XMS (1.65v) installed.
Another pair of the same RAM chips will only cost 25.00 euro.
Otherwise, 2x4GB Corsair DDR3 1600MHz CL9 Vengeance (1.5v) for 50.00 euro.

Would it make a noticable difference to the speed I am currently getting out of my PC if I do upgrade?
If price was not an issue which option would I benefit more (if at all) from:
1. 4x2GB Corsair DDR3 1600MHz CL9 1.65v XMS
2. 2x4GB Corsair DDR3 1600MHz CL9 1.5v Vengeance

My Setup:
Gigabyte GA-H55M-UD2H
Intel Core i5 660@3.33GHz LGA1156
2x2GB Corsair DDR3 1600MHz CL9 1.65v
XFX Radeon HD4770
CoolerMaster Silent Pro 500W

Many Thanks

I assume you have the required 64 bit OS? Windows or Linux? If so, I would just get the 2x2gb as 8gb is ideal for Win 7 64 bit and it will be good for a while yet.

The only real reason to get the 2x4gb would be leaving slots open for another 2x4gb set.
 

Post link to the RAM. Anyway, I would take 2 sticks over 4, because the failure rate adds.

Corsair Includes XMP performance profile, is 1.5v ideal for i5, but is high profile.

Are u using any aftermarket coolers? If not than u are OK.

I finally went ahead and picked up the Corsair XMS3 2x2GB set for 25.00 euro.

They are a slightly newer version number than the set I already have installed, but the system isn't complaining :)
After 1st reboot I re-ran the windows performance test and my RAM score went from 5.9 to 7.2!
It seems to be running smoother than before without any problems.

Thanks for the input!
