Official Asus Rampage IV Extreme Thread

You get CPU fan error when you've not connected a fan to the CPU 3/4 pin on the board. I get it because i use water cooling, just ignore and disabled it in the BIOS.

No, had no issues at all with this board, been solid since day one.
Is it only since you flashed to 1101?

I had it when my corsair H100 broke on me. No lights. Fan not spinning. So, I took off the fan from the fan connector and connected it directly to the CPU fan header.

I had 2 corsair fan connected with a splitter directly to the CPU header.

well tried all 3 bios including the beta bios none of those made any diffrence and motheorad was showing that all dimms were connected but only 24gb of ram.

tried reducing the voltage to 1.5v and set the timing to match the ram still didnt make any diffrence.

i noticted that in the motherboard infomation disc supplied with the board that it was stating that no memory was installed in channel D1 and D2

so tried it with 4 sticks in insted with 1 stick being in D1 and system was posting 12 gigs of ram.

so removed one stick of ram from channel C1 and then was only posting 8gig and not 12 gig.

so removed stick from D1 and system was picking up the 8 gig of ram installed.

so set it to two channel with one stick being in D1 this time only 4Gig of ram.

finally tried it with just one stick in D1 and system would post at all so looks like channel D1 and D2 on the board are faulty.

YAY im not the only one, I have the exact same problem, did you figure it out or just return the mobo?
 
Solved

Guys

Has anyone of you having problem with "CPU Fan error" on this board?
Click to expand...

SOLVED. :D

When I put the bios fan control into "Silent" mode, the mobo seems to fail picking up the fan pulse as the fan only spins at 200-240 rpm. Set the CPU fan control back to disable and everything's back to normal.

What I don't understand is why it's not picking up the fans rpm when in silent mode when the lowest rpm you can set the fans in the bios is 200?:rolleyes:
 
What are the temps of the board? Awaiting for the board and 3820. CPU will be custom water cooled - my old 1366 setup. But I've read somewhere that Rampage IV can get really hot. So now I'm thinking, maybe I should add board to the loop.
 
The board does not get really hot its the VRM area that does if you push the voltages and add levels of LLC above medium. It can cause CPU throttling but then again all X79 boards are the same. I do water cool the board with EK block but I do use high voltages especially for benching. The 3820 from reports draws less current and hence creates less heat than the 6 Core variants so you may not need to water cool your VRM area.

Its a really great board hope you enjoy it.
 
Thanks for your reply. I'll give a go without putting board in the loop and see how it behaves. Hopefully it will be all right. I couldn't justify spending that much on CPU. And to be fair, I don't really need 6 cores, so 3820 should be fine.
 
Two bios released today, 2002 and 2003. I don't know why they've released two.

2002:

Release Notes:

Rampage IV Extreme BIOS 2002

Improve system stability.

*If the BIOS version is 1404 or older, please install the converter first before you update the BIOS.(contains the converter&the manual)

I'll be going with 2003.

The unzipped files are:

CAP Converter User Guide 1052 KB
Rampage-IV-Extreme-ASUS-2003.CAP (BIOS lile) 8194 KB
Rampage-IV-Extreme-CAP-Converter.ROM 8192 KB​

The BIOS Converter allows you to convert the BIOS structure from .ROM to .CAP for Windows 8 full-functionality.

So who wants to go first? :D

All done!

I went the EZ Flash way with Rampage-IV-Extreme-CAP-Converter.ROM. Both files have to be on the usb stick.

Record your system settings as you will lose them.

Copied current bios to bios 2 then ran EZ Flash (on current bios).

On the first reboot you get a few flashing ROG bios main screens then a screen telling you not to do anything and it gives you a %complete on the bios and iROG update.

Then you get a reboot and wait of around two minutes and the system comes back with the new CAP bios system and update in place.

At this stage you do lose all your settings and have to re-input. RAID gets set back to AHCI so all you need to do is set it back at this stage.

Now on 2003 CAP.

Hi,

You need to disable 'Fan Speed Low limit' within the BIOS, simply put the fan is spinning so slow the motherboard views it as not working. So if you disable this monitor then you can put the Q-Fan settings back to "Quiet" and enjoy a quieter system :)
