Anyone using Samsung low voltage ram? If so, what kind of freq and timings can you get? Not sure what kind of values I should be using pushing past 2133.
Are you overclocking? The BIOS puts a decent load on the CPU and memory and GPU so it could be related to that or just you need to reflash the BIOS. I was able to easily boot at 2666mhz, no issues, stability prob 2400 maybe 2600, you can prob get away with auto timings.

That is better than before. I saw some retails doing only 4.2. Over the weekend i was at the GBT OC lab and some guys went out and bought some CPUs, some couldn't even validate 5ghz some could do 5.3ghz, it is really crazy luck with these CPUs it seems
Maybe Intel needs to update their microcode better.

Obviously, you wouldn't try to test stability with it since it would push voltages to like 1.4+ but if you find a good OC @ 1.2 volts, wouldn't it be smart to leave it at auto so that you can idle at less than 1 volt? I'm assuming that the FIVR and digital power delivery means the auto voltage is much smarter than the Z77 generation.
You can also use offset OC vcore voltage.

I tried offset and the voltage was what I expected under normal loads (1.33V) but as soon as I ran IBT the voltage jumped to 1.43V. So offset doesn't sound like a great idea until we know exactly when it is going to kick up like that.
The read point you used was labeled what? VIN or VCOre? VIN works off SVID so it will change if you leave it on auto.

Even the Samsung utility would not secure erase them as they are "frozen", what ever that means. Of my 3 SSD's I have two back working now but it will probably take loading Parted Magic again and wiping the third one again before it's usable.
I went through this same crap with some Corsair SSD's last year.
Go to install Windows and it says it can't install to the disk.
Drop back and use DISKPART to clean and make a new partition.
Try to install Windows. Starts unpacking files and gets to reboot stage.
Reboots to the install disk instead of into Windows.
and on and on and on and on and on.
Several times throughout the process I used Parted Magic to wipe the disks. Finally when Windows does install you have no idea why or what was different that time around. Weird!
Also it seems the Z87 is doing the same thing as my Z77, that is when you attach up 6 or 7 drives it seems to confuse either the bios or Windows and sometimes makes booting a chore, with me loading optimized defaults often. Brand new SATA data cables, brand new (made by me) SATA power cables. What's up with this? Could be I'm to blame but I had the same thing going on with Z77 from time to time.
No overclocking yet, still working on the rig. Sorry I wrote a book here......
Yea Z87 still is pretty new I am sure Intel will improve their RAID and stuff, but they are also trying a lot of new power saving stuff which might hurt it, for instance the PCH only is 4.1W TDP while on Z77 it was 6.7W, how do you triple SATA6G ports, add 2 more USb 3.0, keep the same number of PCI-E(disable 2 when using max SATA and USB3) and increase support for most everything, yet cut down your TDP? lol.

Edit- turns out I have BIOS F3 newest Is F5, well see if this fixes
In the mean time what driver do I need for "PCI Simple Communications Controller"?
F3 BIOSes came out a long time ago, F5s about a week or two before launch, F6s should be out soon. PCI Simple Communications Controller I believe you need to Install Intel ME(management engine). Time to put the UD4H back on the test bed again.
