KT7A-RAID wont boot. Need to pencil L7 bridges for voltage?

[vagabum]

It's getting late and I'm too tired to mess with it any longer but I suspect I screwed up by penciling in the L7 bridges, think I did 2 and 4. Do these need to be penciled in to take the voltage to 1.85v and beyond? or does the bios already do this. System boots up, no image and gives me 3 beeps if that helps.

System is as follows

300w PS
Duron 700/Super Orb
256 Micron Cas3
KT7A-RAID
Matrox G400
SB Live
Accton 10/100 LAN
Intel DSL modem internal
CD drive
CD burner

Do you have your CPU Fan plugged into CPU fan Header 1? If you are looking at the two fan headers together at the top of the board, CPU fan 1 is the second one to the right, not the first one on the left. You must have a fan plugged into it in order for the system to boot. If you do have a Taisol fan plugged into the correct header, a forum member the other day found that it would not work. He plugged in a 3 pin higher RPM RPM monitoring fan, and the system booted. The fan must be a 3 pin/3 wire fan with RPM monitoring.

EDIT: there really should be no reason to pencil your L7's at all. If you want the chip unlocked, you pencil (or better yet use Loctite conductive paint) the L1's

EDIT: I see that you have a Super Orb, and not a Taisol. Do they have 2 separate fan plugs, and are they 3 wire/3 pin plugs? Maybe just one of the fans plugged into CPU fan header 1 is not giving enough RPMs for the system to boot,

No need to do the L7 anymore, Bios handles it. beyond 1.85 requires voltage mod last time I checked.

Yeah, like cpars said. If you're not posting, erase the pencil lines on your L7 bridges and let your BIOS take care of the voltage settings. Much easier/safer that way.

Three Beeps with my Intel board was the memory was not in good..
Wrong fan header wad one long beep I think.. I just did this a few days ago boots for 30 secs then shuts down fan header 1 is the one on the left of 2 and not closest to the processor...

Got up this morning and remembered 3 beeps meant video card in the KT7 FAQ, I still thought I'd screwed up by doing the L7 but there's no harm in trying the video card before pulling it all apart again right? went to pull out my g400 and replace it with an older card and... hang on, hey, it goes down some more!

Yep it was the video card, have to push the card harder down on this one than the old BH6. Multiplier can now be changed and the voltage can also be pushed past 1.85v. Does anyone know if the KT7A does this on its own? or if it was my penciling of the L7 bridges that did it.

Technonut - yes, there are two seperate fan wires, both 3 wire. I'd plugged them into the right fan plugs. Both fans do 5000, and 5500 RPM's respectively so regardless the board will boot up anyway

System is now running okay. No o/c-ing yet. Messing around with the Bios and IRQ's. Thanks everyone!

Just got the same board on Tuesday and on Wednesday (on my lunch hour) I was trying to goose a few extra MHz out of this puppy (T-bird 1GHz) and go for 9@133, rather than the 8@133 I was doing. It refused to post and so I thought I'd just reset the BIOS and try again. My other board is a Soyo 6BA+IV, and has a soft reset from the keyboard by holding down the left shift key.

DO NOT TRY THIS AT HOME!

Turns out this not only clears out the settings, it CLEARS THE WHOLE BIOS!

To top it off, Abit's ftp site wouldn't respond, and then the BIOS I snagged from athlonmb.com gave me a checksum error!

So, with visions of "Oh my God, I've trashed my brand-new board, I'm such a moron!" I tried downloading the newest version of awdflash.exe, rather than the one that came on the mb's CD.

Turns out (there's alot of these huh?) that the version on the cd is 18 MONTHS OLD and incompatible with newer BIOS's.

SO, everything's okay now, just need a better HSF!
