Ok so it seems they are saying 1.65v ram is fine on ivybridge. I thought it would be with the amount of "ivybridge memory" that is 1.65v

In fact they even recommend 1.5v ram for use with an i7 920, even though I am pretty sure 1.5v ram was not around when it was released. I think we'd only just gone down from 1.8v ram to 1.65v!

See below for the chat I had with them.
Jenny: Hello. Thank you for using the Intel Customer Support chat service. We are glad to be of service. How can I help you today?
: Hi, I just wondered if the i5 3570k supports 1.65v DDR3 voltage?
Jenny: The recommended memory voltage for Intel Core Processors is 1.5V.
Jenny: We do not recommend going higher than the recommended voltage as it may shorten the life span of the processor.
: Ok, so for example if I was using a Core i7 920, would 1.65v DDR3 voltage be ok?
Jenny: Intel® recommends using memory that adheres to the Jedec memory specification for DDR3 memory which is 1.5 volts, plus or minus 5%.
Jenny: Anything more than this voltage can damage the processor or significantly reduce the processor life span.
Jenny: That is 1.5V +-5% or 1.575V.
: when the i7 920 was released the lowest available voltage DDR3 was 1.65v though?
Jenny: We normally get reports from customers using the recommended memory voltage which is 1.5V.
Jenny: Anyway, memory modules rated at 1.65V normally operate on just 1.5V.
: true, but some of the higher end stuff will not run at 1.5v
Jenny: You can double-check this in BIOS to ensure that the processor will not get damaged.
: ok so if I run 1.65v ram on an i7 920 will my warranty be void?
Jenny: No, if 1.65V of memory is used, we can still provide warranty replacement for the processor.
Jenny: That is still acceptable.
: ok, is that the same for the i5 2500k and the new i5 3570k?
Jenny: However, if there will be any visible burnt mark due to high memory voltage, that's the time warranty will be void.
Jenny: Yes.
: ok thank you
Jenny: You're welcome.
Jenny: Nice chatting with you.
: thats all thanks
Jenny: Thank you for visiting the Intel Customer Support chat service. I look forward to chatting with you again. Have a nice day!

I do think they are just quoting the JEDEC specification all of the time to be honest.

I wonder what they'd say if I asked them what voltage DDR3 ram I can use with a core 2 series CPU, 1.5v ram was not out then!!

Not exactly a ringing endorsement to Sandy Bridge and Ivy Bridge users.

"You can use 1.65V but if we can tell it damaged your processor don't come crying to us".

It's almost like they expect it to.

Their quote was "visible burn mark", which I have never seen myself on any recent CPU, have you?

A quick google search of i5 2500k burn mark brings up nothing!

Just out of interest, what is the issue with running +1.5v and how does it shorten the life of the CPU? Thanks.

I and many others do not think there is a problem with running 1.65v

There's a thread here where it looks like the CPU socket pins have been burnt to the processor.

Pretty sure its impossible for a CPU socket pin to melt to a CPU.

The pins are made of a copper alloy with gold plating and a nickel underplate, not likely to melt afaik!

I am not saying it could not happen but I highly doubt it, if your pc is getting that hot to melt the socket then I think you'll have more to worry about... like a fire.. lol
 
Surveyor said:
I'm not saying it melted but they appear to have become fused together.

Which would mean that one of the metals would have to melt slightly surely?

It would also be almost impossible to do as for it to get that hot and cause no damage to the pins around it would be unbelievable.

I'd guess it was more like the original owner damaged a pin so it was upright and then tried to install a CPU in the socket.

Anyway this isn't really the point, point is I've not heard/seen anybody with a burnt CPU. Even the guy on here who decided to put 1.8v core voltage through his sandybridge which killed it :o
