It is the Intel i7 3770K Ivy Bridge and can handle that frequency. I looked into that already and others have had 2666MHz with that CPU. I just looked it up and my ram isn't compatible with my motherboard apparently so I will have to order new ram.

Well, not all compatible RAM is on the RAM compatibility list (not all is tested); I am running Patriot G2, which I don't think is on the list.

That's true, I thought about that too. Unfortunately I can't find anyone running the ram I have with my motherboard.

I looked on Intel's site for the compatible XMP setups and my combo wasn't on there, which I know they aren't all tested, but when I go onto Corsair's website my ram doesn't pop up as being compatible with my motherboard. This is what I have- CMD8GX3M2A2666C11 (Corsair Dominator Platinum 2x4GB 2666MHz) but it says CMD16GX3M4A2666C10 (Corsair Dominator Platinum 4x4GB 2666MHz) is compatible with my motherboard. Is there any reason these kits would run differently on my board? All I can see different is the latency.

Recent BETA releases for UD boards mention "Enhanced memory capability," so maybe you want to wait a BIOS update for G1 Sniper 3.

Also, yes CPU has a lot to due with RAM these days. Not every 3770K can handle 2666 Mhz. For this reason Intel guarantees 1600Mhz with Ivy Bridge and 1333Mhz with Sandy Bridge. Not every 3770K has IMC that can handle those frequencies.

Did you try to set values manually, and increase voltage on VTT/IMC yet?

I never thought about ram and the processor. I know I've seen others run 2666mhz with my processor just a diff mobo. I couldn't get profile 2 up in xmp or properly OC it without it restarting on me. Not sure what to do from here. I might email corsair and ask about this ram in my mobo.

I've been playing around with the numbers but not sure what they should all be at. Just plugging them in and hoping they work. I changed my voltage to 1.65V because these cards are 1.65V and the slot on the mobo is 1.5. But I haven't changed the VTT or IMC. what do you recommend?

Recently had the 2700k i7 and just put the 3770k i7 in today hoping it would fix the issue. But I'm afraid it might be the ram and mobo conflicting. Usually I'm better at fixing these problems but this is a real stumper.

It's the silicon lottery; any clock speed above the manufacturer spec is not guaranteed.

hey man whats up. I have that memory but the 16gb version.

Here are a few things you can do:
first of all profile 2 is for 2400mhz, its for sandy or other platforms, profile 1 is what you need. If it isn't stable then do this.

Download the latest BIOS, go down the to bottom of advanced memory settings. Change to quick adjustment, not expert(you have to do this to change the setting), find Data Read(and write) Slew Rate, change both to 2 if that doesn't work set 3.

Okay then if that doesn't work your CPU will need to increase VTT voltage or IMC voltage, so try set VTT to 1.15 and IMC to 1.145. If that doesn't work then try 1.200 on VTT and 1.195 on IMC. Don't set 1.4v or 1.9, be carefule. You want to be 5mv lower than VTT on the IMC voltage for the voltage to stick.

now if that doesn't work then it might be an issue with XMP, try these settings:
http://www.overclock.net/t/1339714/z77x-up7-performance-review-and-cpu-memory-overclocking-guide#post_18914847

you can try those timings, also make sure your memory is in the green slots.

if you set 1.65v it should do 1.65v if vdram isn't working then flash your BIOS again, then power down(unplug the PSU from the board) and then clear the CMOS and remove the battery. On the new BIOSes a full power down is required to avoid all issues with stuff like voltage not working.2666 dominator plat c10 are samsung, they can take upto 1.85v on air or even higher like 1.9v, but they don't scale much over 1.8v. For 24.7 stay under 1.75, they don't get very hot either

Thanks man finally my search is over...I've been wondering where the profile 2 was for the last 2 days, wasn't sure if profile 2 wasn't showing up because of my ram or something.. I'll try that when I get home in a couple hours. Hope it works. What mobo are you running?

I was thinking about buying the 16GB instead and returning the 8GB.

Right I had my Intel i7 2700K overclocking at about 5.2 with my previous mobo and ram. gonna get this one going soon and see what i can take it too.

I just stumbled upon this:




Its for the UP7. Does anyone know if it fits the sniper3? Just by looking at the heatsinks, they seem similar. Anyone have any thoughts???
