RAM

[MoogleViper]

Ok so the RAM I bought isn't compatible, so I need some new RAM.

 

I was thinking of either this:

Kingston 4GB (2x2GB) DDR3 1600MHz HyperX Memory Kit CL9 1.65V XMP ~£29

 

or

 

G-Skill 4GB (2x2GB) DDR3 2133Mhz RipjawsX Memory Kit CL9 (9-11-9-28-2N) 1.6V ~£44

 

Will I notice the difference in speeds? Is it worth the extra £15?

 

I have an i5 2500k processor and an ASUS P8P67-M mobo by the way.

I doubt you'd notice the extra speed. Both are good brands, but the biggest difference I see after speed is the G.skill has the same latency(at a higher speed, impressive), and a lower Voltage. If the voltage isn't a typo that is. Lower is better as it won't burn out as fast and gives overclocking headroom.

 

Unless you plan on some crazy overclocking get the Kingston. Even so the Kingston is still probably good for that.

I had that brand of Kingston and it was good.

Actually Intel recommends using 1333 MHz DDR3 RAM, see here.

 

I have CORSAIR DDRAM3 4GB CL9 TW3X4G1333C9A with my i5 2500 if this is any help.

That's the speed of memory it is currently clocked for. RAM and CPU go hand in hand when overclocking. However, dropping in a stick that is clocked higher won't really matter it will automatically be matched to the CPU's FSB, and downclock.

 

When I replaced RAM in my old laptop I got DDR2 800 even though the laptop itself would only run at 667, the RAM automatically went to 667 speeds.

Here's a nice article about Sandy Bridge and choosing DDR3 to go with it:

Their conclusion is that DDR3-1600 is probably enough, and faster RAM doesn't yield a decent performance increase in real world applications.
