Theres a vendor site in U.K. showing various ASUS C2 mobo as available 10-2-13.

As I see it, retail sales of non essential consumer items is very depressed right now, perhaps causing the natural depletion of C1 inventory to be slowed, repeatedly forcing the C2 intro date into the future. Also I have read that the more popular models will be avail in C2 first with the slower moving ($300) mobo only becoming avail even later yet.

You are absolutely right, unfortunately... :(

1. Getting a pic/info for you: I'ts an alu heatsink that has an anodized coating in the water channel from what I just got told.

2. Should be C2 as far as I am aware (will get confirmation). Impact is C2, so I would have thought this will be as well. EDIT: Formula will be C1 for a while. Impact will be all C2.

Amazon sent me a c1 Maximus VI Hero. I assumed after being out of stock for over a month the next batch would be c2. Going to return it (didn't open it) and rebuy it in a few weeks I guess.

2) Don't use XMP profiles. Will result in all kinds of flakiness and instability, from corrupted audio to random restarts and bluescreens (blaming Nvidia drivers, no less). This was actually pretty crippling until I figured it out.

I'm going to guess that this applies to other manufacturer's Haswell boards as well? Does not using an XMP profile keep the memory speed down to DDR3-1600? Or is it possible to take advantage of DDR3-2400 without that?

XMP (xtreme mem profile) timing paramaters are programmed into that little 1/4" square black (SPD) chip on memory pcb. Its there just so you dont have to manually set all the timings by yourself, since most endusers dont understand them anyways. But you can set them to anything you want in bios and see if they will fly..

I have found Crucial Ballistix Sport (comes as low profile) to be the most compatible Z77 Z87 RAM (they only use their own manufacture dram chips - Micron - of same density) and thats what I would buy. Since the memory controller is now on the CPU die, theres no more bottleneck and DDR3 1600 is just fine. You will never see or feel any difference in daily use. Of course mem BENCHMARKS will be quite different. But who cares. (And DDR3 1600 should show as one XMP profile choice).

One special warning:
Do not insert or remove ram with PSU plugged in and any lights still on. The ram slots only have a lock on the upper side, so to insert or remove you must ROTATE the right side of RAM to manipulate stick out of the lower non releasing locking tab. This can cause arcing if PSU is plugged in (+5VSB current flow). One half of RAM is out of slot and other half is in at various contact tab depths.

I have no issues using XMP with the setup in my sig (both sets - have a duplicate setup)

The new Asus boards seem to have the term "XMP" overloaded -- it isn't just a memory timing choice but also a setting for the "AI Overclock tuner".

I selected DDR3-2400 from the memory speed menu without selecting XMP, and it automatically picked up the correct 11-13-13-31 timings for my memory. It has been running for 28 hours now (knock wood), we'll see if it can stay that way.

This is the C2 stepping intro thread -
Haswell Ram issues is getting way OT, and so just FYI heres a lttle vid on that subject:

http://www.youtube.com/watch?v=ub6WnHmiIOs

Kinda drags on, but explains a lot of the new overclocking variables with the Haswell that you must know about, like the relationship between super fast Ram and the resulting CPU overclocking restraints.

ASUS C2 all over Germany now

Edit:
Found this on a Gigabyte related PC Forum
Have no idea if its true or not

Are the part numbers different from the C1? Also, did microcenter have any C2s for the Extreme3 or Extreme4 line?
Click to expand...

I am not sure for ASROCK if the part numbers are different or not, but I am sure they did not have any other C2 stepping boards except for that 1 single motherboard.

My best guess is that for USA we may need to wait until the end of October or early November.

A vendor on Amazon (ALB-System) is advertising 7 or 8 ASUS C2 boards but they note delivery 1-3 weeks, which I assume means they are preselling boards based on what they were told about delivery. Note that they are showing no boxes - I assume because they dont have any. Also their customer approval is a bit mixed I would say.

http://www.amazon.com/Asus-90MB0DT0-...ywords=ASUS+C2

http://www.amazon.com/Asus-90MB0EH0-...words=ASUS+z87

http://www.amazon.com/Asus-90MB0EF0-...words=ASUS+z87

http://www.amazon.com/Asus-90MB0ED0-...words=ASUS+z87

Looks like ASUS C2 will be first out (in US) with ASR being second and MSI and Gigabyte straggling in last.

OOOPS!
Just noticed ALB ships from Germany, so that explains that

Just got back from Microcenter. I bought a 4770k and Asus Maximus VI Hero. It has the old part number: 90MB0FU0-M0AAY0 but it is C2 stepping.

So It's good news, it seems that the 90MB0FU0-M0EAY5 isn't a requirement to get the C2 stepping boards. :thumbsup:

Thnx m8te
Interesting - VI Hero ROG mobo does indeed appear to now have SB C2
Last time I looked (Aug 8) it was C1

all current retail ASUS Z87 are C1

The $64,000 question is whether the mobo makers will eventually offer an exchange for C1 mobo, or perhaps a resolder of SB, or will they just leave everything as is. I guess I will have to call Intel one of these days to find out. No one else seems to know.

@bankster55

I am wondering what program was that? I know that CPU-Z could read, but I am wondering if there is any other program could do that same. Or is that part of the BIOS information?

I'm picking up a Hero from my MC tomorrow. I'll let you all know what it is.
I also ordered a Gene from Amazon - I really hope both are C2. I'll be returning them if they aren't. Has anybody heard if the Gene's are C2?

Can you also check if they have any asrock boards that are C2 other than the mini-ITX version? Maybe one of their extreme lines. Last time I went, they didn't have much C2s.

If you could please also check the Part Number on the outside of the box. This would help to identity whether C2 could be told from the box, as user report that c2 board still has the old part number.
