as long as you keep vdram voltage bellow 1.7v, and vtt(vccio) bellow 1.24, you are fine smile.gif

but for 24/7 1.65-1.66 max is ideal

No, just don't exceed 1.65v for your memory.
Honestly you wont see, or notice any difference.

If I were you, I'd keep it at 1.5v and at 1600MHz!

Wrong, if you take it that high, your taking a chance of hurting your cpu!

sorry man, i know a bunch of people that run >1.65v 24/7 on OCN and xtreme system. I've been running my chips at 1.66v since release date and nothing has happened.

I also know quite a few people running 1.68-1.7v 24/7 perfectly fine.

Sin0822 has benched around 1.76v

I didnt see any difference in performance either. I stuck with 1.5v @ 1600. With my mobo in my sig, I am trying to figure out if putting another 2 4gb sticks in is worth it. I think it will change it so that all 4 sticks will run in single channel which I am not sure is going to help as much as running 2 8gb sticks.

I really don't care what you and your friends do, your giving out bad advice, and should be aware of that. Telling new people that 1.7v for there ram is fine, is irresponsible!

Intel has guidelines, and it's obvious that you don't know any of them!

Max safe on VCCIO is 1.20v. As such, you can get away with up to 1.70v safely on VDIMM, as that's 0.5v above VCCIO.

As such, 1.65v VDIMM is perfectly acceptable, as long as you raise VCCIO to match it. Which is what I said earlier.

So are you saying that Asus and GSkill are liars? The 16GB RAM that I just bought is rated for 1.65v, and is P67 certified, and its on my QVL from Asus.

That's like saying the maximum vcore on a 45nm C2Q is 1.36v because that's what Intel says. But yet almost everyone racked it up to 1.45v.



quote is from a thread on the same page as this... I can find tons more, the people that have fried their chip due to vdim, was actually not because of the vdim being >1.65, but it was because they increased the memory controller voltage along with it, which directly impacts a component on the chip significantly.

*snip snip





Voltages:Now let’s move to voltages, this is very important and I think anyone looking to overclock should have a thorough introduction to the variety of voltages that the user is able to control.
Make sure to pay attention to my tid-bits on Vcore(VCC) and VTT(VCCIO), these are most important for overclocking, other voltages can help too.
Here is a table I put together from Intel’s product data sheet; it defines the processors maximum voltages and maximum amperage- These are OFFICIAL Min and Max Values:
**snip snip

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.

**snip snip

I've personally had multiple 2600ks all of which have ran vdim >1.5v fresh from the box and all of them are still kicking.
In the end it's up to you whether you beleive me or not, but imho... i was NOT being IRRESPONSIBLE when i suggested him the voltages that i knew from my own experience as being safe

Not all memory scales with more voltages... especially centain corsair dims which seem to be really tightly binned so they don't have much headroom going up... however if you buy dims which have different ICs or have not been binned, (mushkin, gskill, or any most IC from PSC, elpida, newer samsungs) you will see huge increases in what clocks you can stably achieve the higher you increase vdim.

Example: Kingston lovo dims which are rated for 1.35v at 1800MHz will scale up to around 1.55v and reach clocks around 2133 with cas 6 or 7, but not scale any farther with higher volts... it's dependent on your ram, IMC, and motherboard

EDIT:btw i am well aware of intel's recommended specs (i can give you their data sheet if you want)

If you had read the first, OP's post, you'd notice he was/is completely new to PC building, and settings, giving advice, such as you did, to a new member, who doesn't know there way around there own bios, is in fact Irresponsible, when your suggesting to them to over volt anything.

And it's not just this thread, I've noticed you giving poor advice in many other posts as well.

You need to take into consideration who it is your giving advice to! Can they navigate in there own bios?
Are there intentions to overclock there PC, or are they just trying to get it running right?
Do they have proper cooling???

So no, I don't agree with the way you give advice, because you tend to jump, instead of taking into consideration, what level the OP is at, and what they want to accomplish.

fair enough, but he did say 1800+ which is overclocking so one would assume he would like directions on what is the best way to do so... so i guess i just should of told him to keep his stock 1.5v on a native 1600MHz kit and up the multiplier.

that would be a success wouldn't it?
