[Skyout]

Hi, I bought myself the trouble motherboard Asus srosshair v formula-z connected only power the motherboard and CPU power as soon encounter the error FF and spu_led lit by pressing the go_button starts flashing Vga, please tell me what troublea.read forums that may be the mother not compatible with the processor via bios or something like that.
And sorry for my Google transliteration)))

Welcome to the Asus ROG Forum,

First because this is a new motherboard you should benchtest your motherboard and all components outside the case.

Follow the checklist below:
1) verify that you are starting off with the stock CPU cooling system; make sure the CPU fan harness is plugged into the CPU Fan Header/Connector
2) verify that both the 4-Pin and 8-Pin Aux. CPU Power Connectors are populated
3) install your video card only; remove all other expansion card and storage devices
4) install only one memory module in the motherboard
5) make sure no USB devices are connected to the system

NOTE: You do need a video card in order for this system to POST; also a FF error may be cause by incorrect heat-sink installation (the mounting screws may be too tight or you are using a water-cooling system which I would NOT install until you are able to get the motherboard to POST).

Hope the translator is able to convert all of this so that is makes sense 🙂

Keep us posted on your progress.

PS: Make sure you have all PCIe connectors populated on the graphic card...also I don't think your Power Supply has BOTH the 4-Pin and 8-Pin AUX CPU Power Connectors...you should consider a PSU which has both.

And so by doing the points of action, the same result as well so I think Cpu_led flashes on the power supply in my Corsair VS 650
I think replace http://market.yandex.ru/search.xml?cvredirect=2&clid=505&text=Thermaltake+Litepower+750W+(LT-750PCNE...
Approach?)
Again Google transliteration)):)

The power supply you specified only has a 4+4 CPU Power Connector which may work depending on the current draw of your CPU; you need two CPU Power Connectors if you intend to do ANY overclocking (one 4-Pin AND one 8-Pin).

Well, if I'm not going to overclock?

[Skyout]

And I saw people used simple 4+4 without additional power supply +4
And I'm not going to take the crazy acceleration(so far=))

Hello Skyout,

i had the same problem. Turnes out my motherboard screws where too thightend to my case. i unscrewed it a little bit and problem was solved.

@Skyout: it seems that some users are able to "get away" with just using the 8-Pin CPU connector where other users have needed to use both the 4-Pin and 8-Pin CPU connectors just in order for the system to POST running a non-overclocked profile....it simply depends on the current draw of the CPU (which varies; that is why some users are "lucky" when they only need to use the 8-Pin CPU connector).

Also when trouble-shooting a FF-Code the first step is to populate both the 4 and 8-Pin connectors (if possible) and if you are going to purchase a new PSU it is always a good idea to plan for the future 🙂
