Thought I'd try my hand at overclocking my setup (in sig) as I haven't had the time since building it a couple of months ago. Anyway, I tried to enable the XMP 3200MHz profile for starters as I've done with other builds, but cold boots seem to fail every time. Applying XMP + warm start seems to work fine.

I've seen this issue a lot on various forums with no real definitive answer. Is it as simple as my motherboard and memory don't get on? Stock settings work perfectly.

I've tried bumping the SA offset and VCCIO just to help the memory controller out a tad, but still no dice.
 
Try the lastest biosfor the motherboard as this is most important on x99 if you aren't already on it. I did find with my 5960x it needed a fair chunk of sa voltage to get ram to run at any kind of high speed. You could also try doing the memory timings manually set to xmp speed with 1.4v memory voltage.
 
My x99 Sabertooth would regularly fail cold boots. I realised I was a fool and had used a split powerlead for my GPU. Once I used two seperate leads my PC stopped doing it.

I dunno if this helps you in anyway but make sure your GPU is on two seperate leads.
 
5820K supports up to 2133mhz memory officially so anything higher is overclocking and there's no guarantee you'll be able to get anywhere close to 3200mhz. Your best bet is to just overclock manually and find the limit of your CPU's memory controller that way.
 
Most if not all HWE CPU should be able to manage 3200Mhz, depending on the board (and memory kit)

The issue with memory overclocking on HWE is that most of the ratios are borked, it's only within the last year that Intel has managed to update the microcode to make things more level across the frequency range in order for kits to work off the bat without deeper adjustments.

That said, 3200 is still the strongest ratio for HWE above 2400. The main culprit is VCCSA voltage can require some adjustments, not necessarily more being better. (Normally between 0.900v and 1.15v) This should aid your cold BOOT issue with passing memory training.

What this means is you'll need to find a voltage for that ratio that works best for your CPU. Also check to see if your memory kit is validated for your board.

Already on latest F22 BIOS so I think I can rule that out. I bumped my SA offset up to +0.300v, which I believe is a decent bump? I tried setting manual timings and memory multiplier with 1.375v, but it still didn't like it. However, with all the xmp boot failures I was having, my system started doing one reboot cycle after each cold start, only after a cmos reset and a couple of boots later did it settle down and start cold booting normally. It's put me off tinkering a bit.

Cheers, but my GPU is powered on separate cables :)

True, but plenty of people do. Not sure if it's a limitation of the board/cpu or the compatibility with the RAM I'm using?

How does that VCCSA voltage translate to Gigabyte's SA offset format and what voltage should I be aiming for? I believe the safe-ish value is around the +0.300v mark?

Got a pic of the voltages I'm seeing:

I had a look at the validated memory kits prior to buying, but the list is very short for Haswell cpus and 3200MHz RAM with only 6 kits shown as supported. I didn't think I'd have too much of an issue as I've seen a fair amount of Haswell builds with high clocked memory and I doubted all their kits would be on the list. Guess it's just luck of the draw outside the validated list...

By the way, the RAM kit I'm using is CMK32GX4M4B3200C14R.
 
Validated kit lists are rarely updated regularly, but the memory vendors specify at the very least the platform the kit was qualified for.

That's a 100 series chipset kit, what this means is it's not likely Corsair binned this on X99 at all, or even in quad channel. That isn't saying it flat out won't work at those speeds, but it means you may have to look a little deeper, relaxing some of the secondary timings would probably be the first.

My advice to you would be to return it, and purchase a kit qualified for the platform you are using.

It was the RAM compatibility Silent_Scone. Got some X99 approved RAM from corsair, applied the XMP profile, 5820k at 4.2GHz (1.18v) - no problems.
