My 4p system cannot boot into anything just show blinking cursor in left top screen.

Mainboard h8qgi-f with four 6180se and 16 memory stick.
Boot into ubuntu 12.04 show the ubuntu booting screen then after 5 second it show only blinking cursor.

Boot into ssd that already have ubuntu os after show ubuntu 5 lines menu, select top one it show only blinking cursor.

Help needed
 
Throw a Ubuntu 12.04 boot disk in the dvd player and see if you can boot from it.

This or, have you tried completely reformatting the HDD/USB Stick and then loading the [H] Ubuntu F@H Appliance?

Folding Appliance

I'd try that and see if it'll boot.


If that doesnt work or youd like more help, hop into our IRC channel.
 
I just use the boot disk(DVD) to install my 2p without problem, boot -> install -> remove boot disk ->restart -> all done. unplug the ssd from 4p put into 2p boot without problem.

i think maybe hardware problem.

will try @m33pm33p method, will update tonight.

If you are overclocking it, you may need to clear the CMOS and start over with the overclock. Look towards the bottom of the first post here for instructions:

Thats a good question. Have you tried any overclocking? You may have pushed it further than it can handle and now it wont boot.

If you were able to throw the SAME ssd/hdd into another computer and it booted without a problem then I doubt it's the OS isntall...
 
+1 to each of the suggestions

Booting Ubuntu installer is the quickest way to assess basic system health
regardless of HDD/SSD/USB state.

[H] Ubuntu doesn't hide kernel boot messages so any issues are readily visible.

OC could also affect ability to boot-up especially if you recently made either OC
or hardware adjustments.
 
spend 3 hour to swap my 4p, problem found to be memory related.
swapping procesor, ssd and memory. system boot into ssd after using my other 4p memory.

but now have another problem

when it start folding (each cpu get stress 100%) my monitor will losing connection and keyboard & mouse is not responding too, but system stay online (my radiator fan and northbridge fan is on).

i'm not using H bios right now so no overclocking is possible.
 
Sounds like overheating. Do you have an external system on your network set to read the log files? Are you able to access any shared folders when the monitor / keyboard / mouse stop functioning ?
 
If you haven't already done so, I'd recommend that you make 2 full passes of memtest86 and
ensure no errors are reported (so memory gets clean bill of health).

You def want to make sure you can narrow it down to the correct problem. It may very well be what you think it is or it may be something that is no longer showing itself and may begin again in a few days. Then you are back to square one..
 
I agree with you @tear, powering up 4p without point using 860 watt psu is wasting electric bill.
i will do memtest tonight.

update: finish all memtest without problem but still cannot fold even for 1 minute. anyone can help me rma the mainboard?

What do you mean when you say "it cannot fold" ? What are the exact symptoms?

Please provide relevant logs/screenshots/etc.

Did you follow our Ubuntu setup guide? Or are you using [H] Ubuntu appliance by any
chance? If so, we may have add'l troubleshooting options available at our disposal.

Have you checked idle and at-load CPU temps? (use: sudo tpc -temp)

I'll mention it again too. If you can, hop into IRC and we'll see if we cant help you. It's sometimes easier to troubleshoot when we can actually talk to you while you're doing it.
 
If it is not overclocked I would put money on memory or improper seating of chips. You have to be extra special to fubar a 4p g34 board w/o OC.


Already a lot of good information to try. If you've not tried any of it, shame on you.

Do post screenshots and/or logs.
 
I buy my first 4p from musky, second 4p from core32.

My second 4p have problem when i receive it, the cpu1 pin is bend on the mainboard, i got it fix in supermicro, then fold without problem about 28 days. Then problem coming, it just wont boot into os or ssd, then i swap first 4p procesor still have problem, then swap ram it finally boot into os. 5 modules of 16 modules ram is bad. My first 4p cannot boot after swaping ram.

Now i think i solve the problem, but everytime fah download wu then start to load balancing the board will just shutdown (ipmi led southbridge fan remain on, monitor going into stand by mode) and the water temperature drop from 40 celcius into 35 celcius meaning only 4 prosesor under stress.

Core32 told me before to post my problem here, but i feel little uncomfortable because english is not my native language. I only know windows, for ubuntu my level is beginner.

For second 4p i already buy 16 stick 4 gb ram and all finish memtest. And now first 4p fold using core32 cpu. I will join irc channel on monday and post screenshot.

Btw how to join irc channel using ubuntu?

Thank you all for your help here to respond to a newbie really appreciated.
 
Don't worry about your level of Linux proficiency; feel free to ask if anything isn't clear.
We'll then explain in more detail.

[I find it unusual for 5 DIMMs to fail... I'm not getting at anything -- just making an observation.]

But, that aside, if you haven't already done so, check your WC loop for any leaks; these
slow drips can be killers.

Immediate shutdown looks like some sort of overcurrent or overheat issue.

AMD CPUs have a mechanism that, with appropriate circuitry on board, makes the board
shut the system down in case of CPU reaching critical temperature.

That said, first, ensure that your water blocks still have a good contact with your CPUs.

Second, check your temps before you start folding -- run the following command:
Code: 
sudo tpc -temp
Copy and paste results here. You shouldn't "generally" see them above 40 deg.
They should also be fairly even [+/- 5 deg].

If you see a node above 50 deg with no folding -- that's a red flag.

Also, try monitoring temps (from second terminal) right after you start folding -- run "sudo tpc -mtemp"
-- this will refresh temps every one second. Monitoring will tell you how the temperatures
are rising and will also allow you to tell last recorded temperatures before shutdown.

PSU overcurrent protection is also a possibility but, given that power isn't completely
taken away from the board I would think it's not as likely.
Still, it does make sense to:
1. Inspect all power connectors for signs of overheating (melted and/or oxidized connectors)
2. Test the system as-is with another PSU (of appropriate power).

What power supply are you using?
 
Are the temps you posted Idle or folding temps, If they are folding temps how long were you folding before you took the picture.
 
Water temperature when all cpu idle
Click to expand...
36C is 40-50% higher than it should be at idle, assuming a moderate room ambient temperature. And that is based on air cooling experience, not even water.

Looks like tpc is not present, please install tpc per this post just so you get more compact output: http://hardforum.com/showthread.php?t=1669698 [Packages section]

Was "sensors" output captured with or without folding?
Click to expand...

yes it capture when folding, this screen shot is my first 4p.
my ambient temp 30-36 celcius, it need to turn AC on to reduce ambient temp to 24-26 celcius.

just remove my second 4p from watercooling, will test it with air cooling so i can watch closely.
 
last update : throw my mainboard and processor to supermicro and just got update mainboard will need repair due vrm issue in near cpu 3 socket.
So I need spare mainboard...
thank you all for your help.
 
That sucks.

Remember that, when watercooling, airflow over motherboard becomes very, very important.

Blowing air at unsinked VRMs is a minimum IMHO.
