Can someone please answer this question for me ,does memory DDR3 that requires higher voltages e.g 1.65 over .1.5 lead to higher processor temps when over clocking ,or is the memory voltage arbitrary when it comes to cpu temps . I am asking this in regards a i7 2600k ,thanks ;)
 
You shouldn't be using RAM which requires more than around 1.5V for Sandybridge.

Quote from OcUK "Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher could limit lifespan of the CPU".

May I ask why you have 6GB of RAM? Sandybridge is dual channel so you would normally have 2,4,8 or 16GB. 6GB may be OK if it's 2x1GB+2x2GB but if it's 3x2GB it will be running in single channel mode.
 
"OC UK have run ram that is 1.65v in Sandy Brigde and they have had no ill effects at all "please read up on this?
6 gb or 8 gb what does it matter,as long as it runs in dual mode and memtest said it did , does memory voltage effect cpu temps ?

Feeling a bit tetchy tonight?

OcUK have tested RAM at 1.65V for a relatively short period of time. It is not recommended to use more than 1.5V long term.

OcUK just put that recommendation on for laughs :rolleyes:

Hey, if you want to risk frying your processor be my guest.

Here's a quote for you:

HI there

Right memory at 1.65v seems absolutely fine, still not a single issue with our rig, still going strong in prime.

I think the issue is coming from anyone trying a combination of the following:-

1. High Vcore
2. High frequency memory
3. High Vdimm

I think when your trying to push its just too much for the CPU to deal with voltage wise.

These chips to get the best results shoud ideally be set at:-

1. 1.35-1.40v Vcore for maximum overclock and ideally 1.30v for 24/7 running.
2. Keep memory frequency ideally around 1600MHz and tighten the timings up.
3. Keep memory voltage sub 1.55v
4. Keep chipset/pll at default and BCLK at 100MHz.

I think the above setting will yield 4.6GHz-4.8Ghz happily but with complete stability and a system that run around the 75c mark.

Now why don't you go and read up on this.
 
Feeling a bit tetchy tonight?, it wasn't just last night ,it's been one of those "weeks".I've been in pain all week following a sports injury .:mad:
