Reboot problem

Whenever I make a change in my BIOS, save and exit, my pc restarts normally(though it seems like the Mach II kicks off a little roughly). When it starts back up again, the green light goes out, the two yellows come on, and the red one is flashing on the Mach II. According to the Prometeia manual, it say a problem with a sensor or connection to the chip controller. The unit is only a little over a month old and has always had this problem.

According to Everest, the unit is still cooling my CPU. It's just that the wrong lights are on. And every so often, it will blow the 6.5A fuse.

When I exit BIOS by "discard changes and exit", everything operates normally.

This only happens when I make a change in the BIOS. It's getting to be a pain in the butt trying to OC my PC since it takes 5 minutes in between changing a BIOS setting.

CPU is X6800, mobo is ASUS P5W DH, and Windows Pro x64. Because Prometeia does not support 64 bit Windows, I am unable to install the software.

Anyone have any idea what is wrong?
 
There are other guys with more experience than me here in the working and control of machs.

I can tell you that ASUS have put an annoying cold boot feature into their recent BIOS's (which essentially is an auto switch off/switch on system that confuses the mach forcing it to shut down and restart too many times) - to overcome this I used a spearate PSU for the mach and that work really well coz I can switch the pc on/off as many times as is needed without worrying about the mach. The way it works is that you fire up the mach by bridging hte blue/white wire (I touch the case with the two prongs a few times) so that teh mach starts up, when the mach reaches say -40, turn on the PC and the 2nd PSU and you are away ;)

One word of warning though - when switching off make sure (if you employ this method) that you switch everything off (including the mach) I accidentally switched the PC off and left the mach on overnight - I woke up to a blown board :(

I trust you will be entering your scores into our 3d team?? :)

Yes the asus mobo does have this very bad problem the way some of us get around it is by running a seperate psu to power the mach, but what that also means is you need to use a power switch on the mother board to switch it off and on.

You also need to run the mach up to boot temp then plug the mach into your seperate psu

WARNING DO NOT LET YOUR MACH STOP AND START WITHIN SECONDS OF ONE ANOTHER THIS WILL DAMAGE YOUR MACH!!!

Thanks for the advice Mav. If I ever get this machine working and oc'd correctly, I'll get some smokin' scores for you.:D

I'll try your route using another PSU. If you wouldn't mind, could you give me directions as if I was a complete nOOb.:$ I'm a little confused about the wiring.

Thanks again.
 
To jump a psu,simply connect the only green wire in the main atx plug to any black wire in the plug,using a short length of suitable wire.

Why wasn't this mentioned?

Does it fix the problem?

I can't try it since I'm using Windows Pro x64 and the Mach's software doesn't support x64 OS's.

your link doesn't work. should be http://www.extremecoolingtechnologies.com/news/more.php?ID=30

Can anyone confirm if this or the new p5b bios fixes this problem?

Will the firmware work on a regassed mach 2?

looking for a new board and the only thing stopping me going for the p5b-deluxe is this isssue
 
I was told by CrazyPC last week that Prometeia is working on x64 software for the Mach II, which will allow me to update the firmware to fix the reboot problem. Let's hope the hurry up.

I might be in a position to test the new BIOS tonight if no-one else beats me to it.

The firmware isnt affected by the gas inside the unit ;)

That would be great if you could check it.

Regarding firmware, are you saying that GT firmware is ok on a mach2 (regassed so what is essentially a mach2 GT)? It doesn't run the compressor in a different way or require the fans to be set higher?
 
OH! Sorry I thought you mean like R507 in a GT or similar.

The differences between the standard and GT are (IIRC) the LCD and the gas, but as long as the conrtol board is the same, it`ll be fine.

I`ll try and test that BIOS today, i`m waiting for a F@H unit to finish, then I`m reinstalling windows
 
BIOS 0711 does NOT solve the start-up pulse.

-> What I have noticed though, is that its an overclocking thing. If everything is at stock, it doesnt happen.
 
I partly take that back....Its not as bad. Still does it after big BIOS changes and from cold, but a normal restart is ok
 
If ya have a good memory, ya could not connect the switch-> Prom and Prom-> mobo cables, and start everything manually...as long as ya dont forget!
 
Ok in the other post about this issue I have my pc set for 24/7 use x6800 420 x 10 using firmware 937 and have no issues, I have also gone into the bios and changed the fsb after a restart and still no double boot problem so maybe the firmware will work unless you are doing huge overclocking changes in the bios

firmware here http://www.extremecoolingtechnologies.com/support/downloads/FIRMWARE937GT.ZIP I have also just spent a few mins in the bios changing vcore and some mem timmings with no double boot issue
