MSI Gaming 9 AC - XP941 HELP !!?

Question

Hi
I have bought the MSI Gaming 9 AC and the Samsung XP941, at first the bios couldn't recognise the XP941 then MSI´s support team sent me a beta bios and then I could see the XP941 so I installed Win 8.1 by usb key which Ramcity says is the only way to go, but after copying all the files and rebooting and starting Windows for the first time, it comes up with - No boot device found :-(
I tried to write the support again but there is Chinese holidays for a week now :-(
Please help me out... ??

vmanuel, I also have a 3000MHz RAM set. It just comes down to CPU and mobo quality. In my experience, 1 stick @ 3000MHz worked, as did 2 and 3. Once you try to operate all 4 sticks at 3000MHz though, its too hard for the part responsible to drive that speeds.
It's my understanding that a higher system agent voltage can help achieve higher RAM speeds, but without a system agent voltage sensor (I don't have one on my xpower x99 board. Likely the same on the gaming series), I have no baseline to bump up from, nor do I know if the voltage is actually applied.
It's the same for ring voltage, which would affect the uncore speed (or l3 cache. Also increases RAM write speeds significantly). Since there is no sensor for it, I have no idea what baseline voltage there is, or if voltage is actually applied, so I am unsure why the ring is maxxed @ 3.6GHz when other users are reporting being able to run higher speeds, sometimes 1:1 when in excess of 4GHz core speeds.
Sorry for the hijack, but found the RAM bit releveant to my experience.
Nice reply, I almost totally agree. I think the most of cpus can drive 3000 memory modules with 4 stick, but bioses have to improve.
I have tried Asus Rampage V, Giga X99 Gaming G1 and this MSI Gaming 9.
Asus RVE is able to drive 3000 (even now with strap 1, since last bioses), but performance is not according to speeds sometimes. You can monitor all voltages.
Giga G1 is not able to drive even 2666 stable. You can´t reach over +0.400 in system agent, while MSI can reach 0.99. In fact, in MSI board, if you let auto the system agent with 2666, readings are +0.500. For the cpu ring or cache, I have +0.175 working like a charm.
So the MSI is able to drive 2666, helped by memory tryit profiles (hynix 2666 CL14). I guess next bioses will have 3000 profile, and probably system agent will go up to 0.7 or so... Would be nice, MSI, to check exact voltages in system agent and ring or cache through bios or soft...

Great   
Regarding RAM: it is quite hard to get RAM up to 3000MHz even if it's rated as 3000MHz. The thing is: you should focus on CPU OC rather than RAM which overall doesn't give that much performance boost as OC'ed CPU  Also as far as I know, 2133MHz is the guaranteed max RAM speed by Intel (read spec of your CPU whatever it is)
Why you always so conservative??? You remind me Louis Van Gaal football trainer when he was at FC Barcelona... He once said to press: "you always negative, never positive..."
If I ask for bios flashing, reply will be "no flashing if not strictly needed"...
If I ask about problems with 3000 memory speed, reply will be "speeds over 2133 are not guaranteed; memory speed not important"...
So, in case of memory, now I have bought 3000, Should I run them at 2133, when G.skill has tested the modules in several mobos, reaching that speed???
PD: when talking about memory, there is no bricking danger, like bios flashing...
