Hey all, i'm gonna upgrade my ram from 8GB to a 16GB quad Channel but i was reading some forums with people saying some or there ram doesnt work if its 1.65v, So is the G Skill Ripjaws F3 which is 1.65v and 2400Mhz compatiable with my P8Z77-M-PRO MoBo? Or should i just get the G skill sniper which is 1.5v? Thanks

Here are the links for the two memory options

Intel recommends 1.5 for 1600 sticks which it also recommends and says is max - the K chips are made to OC and while Intel doesn't officially support it, it does certify DRAM for it's CPUs up through 3000 - most all of the DRAM from 2133 on up is 1.6-1.65 - as far as the 3570K I've been running 32GB of 2133 or 2400 since the CPUs made available (got an early ES in Jan of 2012), and have about 60 IB builds on K model CPUs (appr 40+ %) with 2133 and Up DRAM, all 1.6 or 1.65 and not a single problem yet

Thanks for your help, nice to see an expert on the topic,
Just one last question, what exactly is the difference between 1600MHz vs 2400Mhz performance wise. Obviously its faster but is this extra speed noticeable?

In simple gaming, up to 3 or so FPS, fast DRAM shines in multi-tasking, video work, imaging, VMs, CAD, anything that uses DRAM as more than a simple conduit for data as in gaming...I often let clients test their systems 'blind' for a while running one or the other then again with the other set, with them not knowing which was which about 85-90% pick the set up with the faster DRAM as the better set up
