LED had positive and negative pole. only light when voltage is applied in the positive pole....so if reverse then no light because it is actually a diode...where current flow on single way only.......

power and reset sw are just basically contacts only....when depress the contact are just close to send a trigger signal only....

i had always use a screwdriver just to on the com. this way....

as for the led, just had to know which is positive or negative will do or just flip around when it doesn't

Thanks for the information AMDnewbie. Can you click on the links to the pictures that I have provided and tell me if I should flip the front connectors around for the HDD and SYSTEM LED? It's kinda weird to have connectors facing two different connectors. One's facing up and the others down. I'm scared to try it because I'm afraid it'll damage the connectors or the motherboard. If enough people can verify it, I will do it. Thanks.

On page 59 of the users manual, it shows a chart of the connections. The power LED + voltages are on pins 2 or 4 of the header connector The HDD LED + voltage is on pin 3. Normally the colored wire in the connector is + and the all white wire is ground. You need to match the colored wire to the plus pin for each connector. The pins are numbered from right to left with the odd numbers at the top and the even numbers at the bottom.

Since the switches do not have a plus or minus side you can leave them as it is or flip them around also if having writing on one side bothers you.

**Sgt_Strider** · 02-05-2005, 11:35 PM

Are you sure it's page 59? I don't have a p.59 in my manual...

**STEvil** · 02-05-2005, 11:43 PM

Look at the index of your manual and go to the page that is listed as having the info on the power/reset switches and hdd/system power LED's etc.

It's on p.17 of my manual and I did looked at it before I inserted the front connectors. So are all of you guys telling me that I gotta put the 2 LED connectors facing up in order to get the LED's to light up?

**AMDnewbie** · 02-06-2005, 12:01 AM

it can't be spoilt....because it is a diode by itself...it glows if current is pass thru from the definite pole n not reverse....if u reverse it then no current can flow thru so the led won't work....

just flip around from ur pic n it will do....

Wow, you're right it worked! I kinda hesitated earlier because of my paranoia, but yea I'm happy now!

lol u noob, take a chance

btw. guys u can unplug drives and fans with the comp on even, i always do. if you memtest overnight you can even unplug your hd after memtest loads, just pull it out fast so it wont short
on my dfi, there was a sticker on the dimm slots telling about you have to turn off to change dimms.

LOL after buying a crappy Asus A8N-SLI Deluxe and selling it at a loss, I wasn't in the mood to buy a new motherboard. I'm pretty happy right now except with the BIOS. I hope DFI address the issues that were mentioned by me and the others and release a good new BIOS!

here is another thing you guys need to be aware of:

If you will use vdimm above 3.2v by switching the jp17 to 2-3,
you do NOT want to use "ZIPPY 700w(6701-p)" PSU. Otherwise, it won't boot at all.
Talked with Oskar already, this is not the problem cause by DFI, it's PSU 5v stand by problem.

OPB

DO NOT DISCONNECT DRIVES WHILE THE BOARD IS POWERED ON!!!!

This will fry your hdd controllers.

Would the PCP&C 510SLI work?

Yes, works fine, OCZ 600w as well

Great! Thanks friend!

you're crazy ? why pull it out ?

anyway i all my hdds in removable lian li rh53 aluminum drive caddies, so can remove them when needed much safer

So which other PSUs have this problem. I wanted to get the Zippy

Yes this info is mission critical...
I have an enermax noistaker 470w ATX v2.0 with no -5 volt rail, will I have the same problem as the zippy?

**HARDCORECLOCKER** · 02-06-2005, 04:59 AM

So I think using a 24 pin PSU, plugging the RAM into orange slots and doing a CMOS clear first will avoid 99% of all problems here........

err why not just have the hds unplugged when its off? If memtest is on a cd or floppy theres no need to even have the hd's plugged in.

The Zippy does have a -5 though, see here:

i think i found that out, saw smoke coming off a hd today. pretty bad day for me, killed a hd, bent a few pins on fx55 (got them straightened out ok) and dfi board won't work with zippy. anway, is there a way i can recover the data on that hd, i mean the platters should be ok right???

**SVTSnake** · 02-06-2005, 07:09 AM

My OCZ PowerStream 520w is working fine (for the moment I guess, there have been a few threads that the 520w has KIA'ed again like with the Neo2).
