I have an i7-960 right now I have it @ 3.6ghz at 1.25v I can get it to oc to 4ghz at 1.38ish volts max temps is about 65c ish at full system load how safe is this voltage also what is the highest safe voltage I don't mind if I go a little higher then the safe voltage, but I don't want to kill the chip any time with in the next your or two

I can get it to oc to 4ghz at 1.385ish volts max temps is about 65c ish at full system load
how safe is this voltage
also what is the highest safe voltage
I don't mind if I go a little higher then the safe voltage, but I don't want to kill the chip any time with in the next your or two
1.45V is max. Some say 1.4V though. But I have mine at 1.43 24/7. I would say you're pretty safe if under 4.5GHz OC, and 1.45v Just check your temps of course.

so 1.385 is 100% ok sounds good also what about running my ram higher then 1.65v I hear theta bad for the cpu, is this so?

Yeah, you're safe man. Of course someone who has a OC'd CPU @4.5GHz might last two years, while the guy who has a 3.5GHz OC might fail in a month. It's no guarantee but yeah your OC is safe. My i7-960 is OC'd at 4.22GHz. 1.432V, and runs 24/7. Also, I honestly I don't know about that. I never go over 1.65v on RAM. I can't help you with that. I just always set my RAM what the box recommends and never OC my RAM anyways.

http://www.mushkin.com/Me.ry/Blackline/996782.aspx I know duel channel in 1366 system, I did not have the money to by a triple channel at the time it runs stable at 1750mhz ish with 7-8-7-24 timing @ 1.65volts EDIT: also can I just by two more of that kit and use it as triple channel I don't see why not but I don't know, I;m know to 1366 systems

are you having trouble with the ram with your current system setup that require you to overvolt your memory?
not at all it just takes about 1.68~1.7v to get 1.8ghz with 7-8-7-24 timings wdflyer
EDIT: And adding more sticks won't make it operate as triple channel ram
why not ? what's the difference ? I'm reading that there is no difference in triple and duel channel kits other then the 3'd stick

Do you change any other voltage to run your memory that high?, or just the VDIMM?
just VDIMM wdflyer
DIMMS are engineered to operate at certain speeds in support of either dual or triple (or whatever) channel designs, it is a matter of the actual design of the DIMM, not a function of the number of DIMMS.
Your memory speed is DDR3 1600, but it is a dual channel designed kit. So where as it will work in your board, but it will only be utilized as dual channel.
so it only works backwards and not forward

The real thing about dimm voltage is keeping dimm and VTT with in .5v volts or less. Example dimm v=1.65 vtt should be between 1.15 to 2.15. No one is going to go 2.15 with vtt. Butt if you ran your dimm at say 2.00v then your VTT would have to a min of 1.5v. My guess would be something would fry.
At least that is the way I understood it back when socket 1366 came out.
Saying what voltage is "safe" for v-core is like saying how many miles you can drive before the brakes of your car will need to be serviced. Lots of variables. Up to a point temperature is more important than the voltage.
I would think your voltages are perfectly fine.

Not sure what you mean,
dual channel ram can be ran as single channel ram that's what I meant

Of course, just like triple channel can be used as dual.

The thing is simply that the sticks are put together to work together.
Tested to work together. Doesn't mean you couldn't add a third stick of same ram and it wouldn't work, it might but no guarantee.

 Yeah man, sorry for the confusion, I am no ram expert either, just trying to help, but I was 180 out. DDR3 Kits are marketed as matched pairs or as sets of three based soley on motherboard requirement/support for dual or triple channel. DDR3 is DDR3, if you have DDR3 DIMMS sold as a pair in a dual channel kit they will operate as dual channel, but if you add one DIMM to the pair, then the 3 DIMMS combined will be utilized as triple channel as long as the board is designed as a triple channel board. Sorry for the chaff, I was checking in the GSkill forum and found the hard answer there. But as awalleyeguy said, matching DIMMS are also a good bet.

There is no such thing as a safe voltage for overclocking, otherwise Intel would have sold it faster and with a heavy premium. Intel spec only refers to stock operation because variations in batch quality mean that a stock part requiring too much voltage or too little won't last the warranty period. For those of us that overclock, we find the best batches (while under warranty can last the longest) end up overclocking the highest with the least voltage adjustment as a by-product. These parts have stock voltages literally in the middle of the VID range on Intel's spec sheets. But the limits of these voltages do not apply to overclocking because frequency change isn't just a number, we're forcing more cyclical loading on internal circuitry and fatiguing the processor. This is why we can't expect "safe" ranges with overclocking, there is just "good enough for short term", so to speak.  Whatever your batch, strive for the lowest stable voltages, don't compare with other batches. For example, my batch was bad, 3836A with a stock Vcore of 1.3125v, I had no hope in reaching 20x180 stable for longer than 3 months even at 1.38. You batch will be on your box if you still have it, do a google search (there may be other Core i7 parts in the same batch, just watch what Bclk and VTT they achieved).

well if you go to high it will kill the chip instantly but I just needed to know some good max volts to run it at and max temps too I'm no ocing n00b just an 1366 n00b  1366 is comply different then any other system I had, it's a lot easier to oc  I don't like that awalleyeguy

thats what I was thinking P.S. here is my cpu-z http://valid.canardpc.com/show_oc.php?id=2032358 it's 99% stable I folded to two days straight, it was fine and all till I whent to reboot into windows, the system froze up for some resin might have just been a programing fault seeing as I made my own Linux os but then again I thought I found all the bugs
