Nope, I used a very similar ASrock board once and had Dominator RAM which was 1.65V while using Turbo50
 
The board is XMP compatible. It basically sets the ram to what the ram tells it to. Should be 1600MHz, 9-9-9-24, 2T, 1.5->1.65V.

This is pretty much my setup. I have HyperX 8GB, the XMS3 will be just the same. You should be able to decrease the voltage manually a little (1.55V, even 1.5V).

Same when you use the Turbo50 option to overclock (4.2, 4.4, 4.6GHz...). Decreasing Vcore a little, to lower temps and stress on CPU. You will need to run stability checks to see what lower voltage you can use, but I would expect around 1.28V or lower if you have a good chip. I would aim at 4.4GHz with that cooler and a long run of Prime95.

Thank you for the reply.
I have been panicking here because I ordered them ram sticks and then read the following underneath the 2500k on overclockers.

"Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU"

That got me worried so I went off reading and just confused myself even more.
Some people were saying that they will work at 1.5 but only if they are run at 1333.

I've been running the same i5 2500K (since May) at 4.8GHz or higher using 1.65v as thats what the RAM wants and never had an issue on two different boards and I know im not alone in using 1.65v RAM with a Sandybridge chip.

Just doing what I've been told to do, basically set the settings to whats on the RAM and it will be fine.

That's your choice but it's not a reason for the OP not to use a lower voltage if they can and follow what OcUK and Intel tell him to do:

- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU
- Aim to keep temperatures below 70c underload if at all possible
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

Told by people at Benchtec UK and reading from this Sandybridge overclocking guide;)

VDDQ: more commonly known as Vdimm or Vdram, this is the voltage for your memory. Formally known as I/O voltage for DDR3, Intel states maximum at 1.575. YOU should run this at whatever it says on your RAM. At the time I am writing this article, 1.575 is not the standard, but 1.5v has been stock voltage on many DDR3 RAM modules for a long time. While at 1.5v you can run at stock speed of 1333 MHz and SPD 9, 9,9,24 to run your RAM at a higher speed, such as 1600MHz, most RAM requires 1.65v. Do not be afraid, if it says 1.65v on your RAM stick, set it to 1.64 or 1.66v. For overclocking higher than what your RAM is rated for you can take this up, I have used up to 1.76v, but for my tests I used 1.72v to run my 1600mhz Ram at 1866mhz. I wouldn’t run this voltage over 1.8v unless you are going for some crazy high clocks.

So I think im safe thanks:D

And he told me that the guide applies for similar boards and Z68 versions, same principles apply.

Yep, BenchTec UK and Xtreme Systems know better than the people who manufacture the processors and the people who've sold an enormous amount of the processors and systems containing them :rolleyes:

You may be perfectly fine at 1.65V, others might not be so lucky.

You've been running the processor for ~9 months. You may be doing damage which will materialise in another 3, 6, 12 months. Or you may never have any problems.

There's absolutely no reason to run the RAM at 1.65V if it will run perfectly fine at ~1.5V.

There's nothing to gain and everything to lose.
 
They may know more about the RAM than people who make the CPU's?:rolleyes:

Also to much Vcore for too long is the main killer of these chips.

But it's the voltage that's being put through the memory controller on the CPU which is the issue not the amount of voltage the RAM needs.

You should listen to the people who know about the CPU's, like Intel ;)

You're just being stubbornly blind to the issue if you can't agree that it's better to use ~1.5v, if you can, rather than 1.65V.

That's a separate issue and not what we're discussing.

I'm not stubbornly blind to good advice which you do give, but I have been told by some serious peeps that just giving the RAM what they require (tested at and written on the label attached to the side of the sticks) at the speed and timings to suit is absolutely fine:)
