I am about to build the following:- Asus P7P55D-E with i5 750. Could anyone tell me which RAM is preferable.
Corsair CMX4GX3M2A1600C7 7-8-7-20 1.65V or Corsair Dominator TW3X4G1600C9D G 9-9-9-24 1.8v
Prices in UK very similar.
Thanks in anticipation.
 


Yes but he said UK pricing so Newegg is not an option !!

OP - of the 2 you listed the Corsair CMX4GX3M2A1600C7 7-8-7-20 1.65V is much better -- tighter timings (7's vs. 9's) and lower voltage (1.65V vs. 1.8V) so would be the better choice.
 


From the OP

Prices in UK very similar

I know that newegg don't ship outside of the US, but he can look for the same RAM in his country since he says that the prices are very similar
 
Another reason that nobody mentioned is that 1.8v RAM isn't supported by current Intel chips. The maximum RAM voltage supported by LGA 1156 and LGA 1366 chips is 1.65v. Anything over that will damage the on-board RAM controller. Just thought I'd mention that in case somebody else checks this thread.
