Question  i5-750? by Nick


Are these compatible with

#37674 i5-750
#37695 ASUS P7P55D EVO




Answer by stevenl on Friday, October 30, 2009
While I cannot guarantee compatibility, this ram should be fine with those two components.

Question  ram voltage by Chris

Is this RAM ok with #36083 I can'd find the voltage for this ram anwywhere but from what i can tell looking at the mobo recommended memory list it can supply around 2 volts i think, so I'm assuming with it being lower voltage DDR3 this should be ok?

Answer by stevenl on Thursday, October 29, 2009
While I cannot guarantee compatibility, this ram should be fine with the Asrock P45TS.

As for voltage, this ram uses a maximum of 1.65v.

Question  Compatability by Robbie

Will this memory work on the Abit Fatal1ty fp-in9 board?

Answer by daniele on Sunday, November 20, 2011
No, as your board requires "4 X 240-pin DIMM sockets support max. memory capacity 32GB Dual channel DDR2 800/667/533 Un-buffered Non-ECC memory" and not DDR3 memory. Try the memory here instead:

Question  work by Len

hi will these work ok with 4GB Corsair Memory XMS3 DDR3 1600 Mhz CAS 9 Triple Channel Desktop and ASRock 880GXH/USB3 AMD thanks

Answer by daniele on Thursday, September 15, 2011
Yes and no - they would work fine with your mobo and alongside 2 out of the 3 sticks of triple channel RAM but you only have 4 slots on your mobo

Question  is this good memory by matt mullen

hi there- i have a quad core q6600 cpu, on a Asus p5kc motherboard with corsair 2 GB of ddr 2 xms memory just wondered if i would see much better performance with this memory

Answer by daniele on Sunday, July 31, 2011
It really depends on what you are doing - if you are editing large files in Photoshop for example then an increase in memory is a great idea. If you are not currently maxing out your RAM though then an increase in performance would be barely noticable, if at all.
