Cpu: i3-530 ( 1333 Mhz)
Mobo: Gigabyte H55m-USB3

Ram: G.skill F3-12800CL7D-4GBECO 4 Gb...1600 Mhz...7-8-7-24-2N... at 1.35 V

http://www.newegg.ca/Product/Product.aspx?Item=N82E16820231321&Tpk=F3-12800CL7D-4GBECO



I am currently using the hardwares listed above. However the memory says " Specifically deisnged for LGA 1156, core i5 and i7"

Mobo Defaulted the ram to 9-9-9-24 @ 1.50 V

I have manually set it to 7-8-7-24-2N @ 1.40 V....... It now displays at 1.44 volts (i think mobo automatically adjusted).....

currently

tCL = 7
tRCD = 8
tRP = 7
tRAS = 24

tRRD = 4 (do i need to change this?)
tWTP = 21 (do i need to change this?)
tRFC = 24 (do i need to change this?)

tCMD = 2 (manually set from 1)

(also other stuffs left as AUTO,

Under Channel A Advanced Timing Control

tRC, 33
tRRD, 4
tWTR, 5
tWR, 10
tWTP, 21
tWL, 7
tRFC, 74
tRTP, 5
tFAW 20

Channel A Misc Timing Control

Static rTD = - Auto)





I am wondering maybe I can get my ram to run at 7-7-7-21 @ 1333 Mhz @ 1.30 V (Current BIOS only allows me to change every 0.1 Volt on memory,....I can't seem to get to 1.35.... so now picking 1.4 instead)

Or it would be unnecessary to change from current state?

Thanks a lot

It seems fine if it's stable. 1.3V might be risky, generally you'll need more voltage to run it at lower latencies so I wouldn't bother.
