Before purchasing my brand new Intel i5-2500K LGA 1155 just delivered, and currently running OCZ HPC Reaper DDR2 8500 1066MHz memory in my present rig which has served me well, last year I purchased some more OCZ memory before they decided to finally pull out of the memory business.So, I purchased 8Gb OCZ HPC Reaper DDR3 12800 1600MHz RAM rated at 1.65v. However,as I want to marry this RAM with an Asus P8PB67 motherboard, I'm a bit concerned with what I have read elsewhere that maybe that 1.65v would be a tad too much for the i5-2500K as I could possibly fry it, which I clearly do not want to do.Any advice or reassurances will be greatly appreciated.

1.65V is the max. I wouldn't reccommend exceeding 1.65. 1.65 will not fry a 2500K.

Thanks for that prompt reply, Ben,and reassurance. No, I was not thinking of overclocking that RAM, only the CPU. I quite fancy the Corsair H100 Liquid cooler but am not sure if I can fit such a radiator in my present Antec 900-2 case even though Antec's manual states that it can be used for water cooling and there are 3 star-split grommeted ports at the rear. I know the Corsair Carbide is designed for the radiator to be fitted in the roof.

One thought, though...just because you set 1.65 in the BIOS doesn't mean that's exactly what you get in operation. You might want to monitor the RAM voltage with things loaded up. I had a mobo that would routinely overshoot the set voltage by .05v. You also might try setting the voltage to 1.60v and the running memtest for a few hours to see if it works OK at the lower voltage. My 1600MHz Mushkin Redline RAM does just fine at 1600 and its rated CAS 6 timings at 1.60v.

I don't think that it matters what the default voltage is set in the BIOS. Most RAM speed incl voltage is tied to the FSB and in the 2500K you can't alter the FSB only the cpu multiplier. So the speed of the RAM is not as important as it was in the i7 9xx series. I've read that 1300 (good CAS latency) is as good as higher speed RAM although I run 1600 myself. I would have thought that when the OP inserts that RAM the voltage should be automatically set by the default FSB/BIOS settings?RegardsPeterH

Thanks for those inputs,Bob and Peter. Worth bearing in mind.Just as an aside,Peter, no idea what part of Oz you are in, but what an Australian Open final that began yesterday and ended today.
