i7 2600k and 1.65v ram? - Page 2

post #11 of 21
Not to say that it's definatly ok, I've been running at 1.65 without issue. Long term that may not be the case, but I'm determined to find out. Same P8P67 basic board, Corsair Dominator 1600 c8 @ 1.65v.

No reason to lower voltage imo. Intel says 1.65v is fine along with all the mobo manufacturers. Just make sure your actual DRAM Voltage isn't going over 1.65. You can probably do 1.6v at your stock settings if your really worried.

I do not understand why would 1.65v hurt the cpu? What does the v going in the ram have to do with the cpu?

I've got a friend running 1.8v in his ram and his 950 was never hurt in anyway. But yeah new platform new bull****

And to who said where we found the info it's on ocuk site look: http://www.overclockers.co.uk/showproduct.php?prodid=CP-358-IN&groupid=701&catid=6&subcat=

I'm no expert on how the inner workings of CPU's but it all depends on where the voltage is coming from. If the voltage has to go through the CPU via the QPI then it could damage the IMC (although this doesn't make much sense since the QPI voltage is lower then the DRAM voltage, just a thought). I really think that it is fed the voltage directly to the ram though which won't hurt the CPU at all at which I agree 100% with you. Maybe if someone could shed light on to where the ram is receiving its power we could put a close on this discussion.

Yeah, but for i7 9xx intels says that absolute maximum voltage should be 1.875V. For i5 7xx and i7 8xx datasheet says that absolute maximum should be 1.8V. And for sandy bridge, there's only mention of ddr3 i/o voltage of 1.5V.

I'm not really sure about all this stuff, but I'll just buy a dual channel kit that works at 1.5V, and not worry about it. smile.gif)

how about 1.65v RAM on a H55 board which officially only supports 1.5v? Will I be able to run it at 1600?
post #17 of 21
H55 is for first gen i7's, not the new ones. What cpu/mobo/ram are you looking at using?
post #18 of 21
I have my 1600mhz 1.65v 9-9-9-24 @ 1600MHz 8-8-8-24 1.56v(not 1.65v) with no problems.

I went with a 1.5v kit to be safe, but afaik no one has actually damaged anything (yet) by running their memory at 1.65.

Still, the specification comes from Intel themselves so I don't know that I'd completely ignore it.
post #20 of 21
On my i3/i5 setups I went all the way upto 2v and was running 1.8-1.9v mostly
On my SB Setup I am running 1.65v No problem
