Hi, I recently got my new rig, the problem is, as it turns out there's a problem with 1.65 voltage on IB, I got Kingston 1600MHz 4x2GB but I've been told it is a great risk (as Intel mentioned) to be @ 1.65, And now due to that statement I'm @ 1333MHz, I just wanted to ask, is there ANY way I could work @ 1600 with that CPU? I get 1.65 when enabling XMP profile and trying to go 1600, on every FREQUENCY below that I get 1.5 (which is perfectly fine) what do I do? ( I want to fully fulfill my RAM's potential and not to feel I actually overpaid , and working on 1333 instead of 1600 like it should be, WITHOUT DAMAGING THE CPU ofcourse)

You should surely get an SSD to improve your overall system performance. I recommend a Samsung 830 or Crucial M4 as I have has good luck with my 2 drives.

omg wtf does it have to do with what I wrote, and I already have a SSD.

Do you have a K series chip? If you do you can purchase the intel over-clocking warranty and run the memory at whatever voltage you want and hope it does not cook. If it does you can replace the chip free one time. The downside is you could almost replace your RAM with 1.5 sticks for not much more than the cost of the warranty.

+1 The Tuning Plan would be a good back up plan.

Here is another idea that may work out. The memory controller on our 2nd and 3rd generation Intel Core processors support DDR 3 at 1.5v ±5% (1.425v to 1.575v). So play with the voltage a little to see if you can get the memory to run at 1600 within those ranges.

Good to know! Thanks! I was always leery of steering away from 1.5V so i got a Dominator kit that is rated for 1600 @ 1.5V but maybe after a while I'll try and clock it up knowing there is some slight voltage headroom. I also purchased the tuning plan. Nice option for enthusiasts.

With this in mind, why do you many RAM manufacturers sell RAM rated at 1.65v? Where did 1.65v come from? It shouldn't be allowed or should be clearly marked that it is not within spec.

There is very little if any real world performance benefit of running 1600 vs 1333 with IB/SB ...

It's overclocked RAM that won't run at 1.5....

Yep, just RAM already running out of spec, both speed and voltage wise. I stick to 1.5v stock RAM, or 1.35v like my current Samsung RAM.
