it has been more than 6 months since the sandy bridge (i5-2500k, i7-2600k) has been released

and still i cant get an clear, certified and trusted awnser to wether setting the ram voltage to "1.65v" is safe for 24/7 or not

some ppl say its safe :ange: 
some ppl say it is not :non: 

who shall i believe?

can some body end this debate plz?
aint there a review or a test conducted by a proffisional website i mean something like tomshardware.co.uk and have evidence that wether it is safe for 24/7 or not?

More about : body end thing

You'll be disappointed to find out that there is no final answer to that question. Some can run certain RAM rated for 1.65v on certain LGA 1155 motherbards with certain processors, others cannot. If you're in the market, then just buy RAM rated for 1.5v and run it at 1.5v. If you're not in the market, there's no way anyone will be able to tell you how stable your 1.65v DDR3 will be at a given voltage, even if they have the exact same CPU/motherboard/RAM setup as you.

well as i am away from intel CPUs, but it's okay for me to run the G.Skill RAM i have @ 1.65 24/7 on the AMD chipset
and if you have doubts which i can't understand you can buy DDR3 1600 @ 1.5 heard and there are G.Skill model (sniper) that operates @ 1.35 for LGA 1156 chipsets

It's safe, but still not recommended to go over 1.6v.

If it's 1600mhz memory, you can run it at 1333/1.5v and tighten the timings, it'll be just as fast.

So if you memory is 1600/1.65v/9-9-9-24 just set it to 1333/1.5v/8-8-8-20.

Nearly Every 1.65v rated RAM can be set at 1.5v(OR EVEN LOWER) on stock timing and stock speed... My RAM can go to 1.5v(Minimum) and at 1866MHz at 9-9-9-24 which is great because it was rated to be at 1.7-19v(Im not sure as it shows on RAM Stick)

Intel spec sheet for SB CPUs stat max voltage for Ram is 1.575.
For what it's worth I'm running 1.60.

Buy 1.25v RAM at 1333MHz(Maybe it's 1000MHz) lol...

@ Cuecuemore i already have kingston hyperx 2000 1.65 ram thats y im asking

@ ilysaml there is a big difference between amd and intel, specially those sandy-bridge cpu's as the memory controller is part of the cpu not in the mb anymore


anyway i will keep searching until i find a clear answer or else i will keep trying until i get it my self, i just hope i dont fry my new cpu

We just gave you a clear answer. Intel suggests nothing over 1.6v.

AMD and Intel processors both have integrated memory controllers.

Neither recommend using ram over 1600mhz.

Take your 2000mhz/1.65v ram and lower it to 1600/1.5v and lower the timings.

that's what i am aiming at, AMD phenom II series have IMC I contacted AMD to know whether i should operate my RAM @ 1600 or 1333 and they said they don't recommend operating any RAM above 1333 according to phenom ii specs, after a hard research i figured out that higher frequency could damage the IMC on the AMD phenom on-die chip over time.
i have G.Skill 1600 CL7 now i operate it @ 1333 CL6 voltage 1.5, even with 1600 MHz i can operate it @ 1.58 without any problem even though it's rated @ 1.6 V

Yeah I have 1600/1.65v/9-9-9-24 and currently running it at 1333/1.5v/8-8-8-20

@soudi

First off you are asking a question there is no solid answer for, simply because the platform has not been out long enough to know whether running 1.65v DDR3 memory modules is going to have an adverse effect on the CPUs on die memory controller.

Since 1.5v is the recommended memory voltage it would be in your best interests to run your memory at those voltage levels for longevity, since no one actually knows how long longevity actually is.

We could help you with arriving at the timings, speed, of your Kingston 2000mhz memory running it at 1.5v, if you would provide some actual specifications to exactly what you have in your possession like the Kingston Model #s, would be a great help!

The only 2000mhz Kingston DDR3 module sets I could find not discontinued are the 3gb kits, so what memory do you actually have?
