why leave it on XMP

and then change the turbo multi

if you wanna oc the ram then yup need to set everything manual.

i have absolutely no need to overclock my RAM...i was mentioning it because the OP's RAM was performing under spec, much like mine was, before setting it to XMP. Video rendering does very little with overclocked RAM when RAM is rated at 1600mhz. That's the sweet spot right now.

Update:
I set it to XMP as you suggested EPC; evidently there was a profile that was available.
It helped a little bit; a video that was estimated to take an hour and 10 minutes (70 minutes) to render before the XMP status, was knocked down to an estimated 55 minutes after the XMP was enabled.
A 15 minute drop-back; not bad. But not super-great either.

It also made my temps shoot back up to 75-80C while rendering. Idle temps are now around 52C; very uncomfortable. =[

The DRAM frequency is still only at 800Mhz. (+150Mhz from what it was before)
The CPU, on the other hand, the core voltage went from 0.984V, to 1.304V; and the Core speed went from 3511.6 Mhz, to 3799.9 Mhz.
(I'm assuming that right there is the cause for the rise in temperature; it auto-overclocked it when I set it to XMP.)
You're able to manually set the Overclock speed in the XMP; right? If so I'll have to go back in and re-set it to stock speeds.

Corsair XMS3 1600mhz 1.5v 4x2GB is what i use, XMP profile has performed flawlessly for me.

1.5v is the key. SB memory controller likes 1.5v for some reason. Low voltage=nice. Not sure why Corsair makes it so hard to find these, and on top of that, doesn't make it obvious that they run default at 1333...trust me, there's nothing in the documentation that says that they have XMP, even though the product says 1600mhz on it...it'll run at 1333 until you find out.

actually...here's a link...i wish they made 4x4Gb kits.

800mhz is normal...that's Dual Channel...800x2=1600. you're good. it's not overclocked...your RAM is finally running at its rated speed whew.

now your CPU....core speed is perfect for stock. if you don't like the temperatures, then it's time for a better option for cooling.

It looks like my RAM is actually running at 1.5V as well.
My CPU was the voltage I posted in my last post.

So; this whole XMP thing sorta-helped, and I'm sure it will help a lot more once I overclock my CPU.
But I'm still a little confused/disappointed as to why the 2600k isn't performing better than the 2500k right out of the gate.

I guess the only thing left to do is overclock. But that raises a whole 'nother problem. To read about that dilemma, I have another post already:
http://www.overclock.net/air-cooling...ggestions.html

Long story short, I only want after-market fans that have the exact same installation method as the stock coolers.

I found one specific fan that looks like it can do the job (and I can mount two fans on top of one another), and it also matches my installation needs, but the people in that post said it's not going to do the job I want. (Which is keeping 4.3-4.5ghz OC below 65C)

All corsair ram has XMP profiles and I have yet to run across a stick that doesn't have a XMP profile. Anyways, back to this high ass idle temp christ! I would recommend taking off the cooler and cleaning it with the cpu and reapplying thermal compound. You have an air bubble or it is not making enough contact causing the high temps.

Try this.

Enable Real-Time Changes in OS
Set Multiplier to 45
Manually set vcore to 1.325 / 1.335

Then try rendering a video.

Also, you may want to try a re-seat if your temps are that high. Even with the stock cooler you shouldn't be seeing those kind of temperatures with stock clocks like that.

Edit - You may need a tad more voltage than that depending on your chip. However, you really shouldn't need to go above and beyond 1.4 unless you are trying to get past 4.5Ghz. Or unless your chip is just a voltage hungry monster.
