ECS K7S5A pro problem

[Directive]

A friend of mine baught 2 MB, listed in title, and 2 Duran 1300 chips. Nether chips work in ether board. Power sends to devises, lights go on, but no signal to the monitor or beeps, no boot. We tried getting Duran 950 chips, same thing. No boot or signal. Just lights to hardware. We tried with DDR 266 and PC133 and PC100 SDram, not at the same time, and no go. What are we missing? :( :confused:

Set the CMOS Clear jumper to Normal? RAM seated correctly? Fan connected to CPU fan header?

Brains! :eek:

The cmos jumper is fine, fans and heat sink are fine. Ram is fine, but I just learned today the duran 950 works with a certain kind of pc133 ram only in slot 2 (dimms 2/3). Its 256 and wont work paired with anything, even one of it's kind, or if this chip is in slot 1 (dimm 0/1). This board is messed up, I told him he should go with an Asus or Aopen board. I have never had problems with them brands. Thanks for what you can offer Peter Missel. If you can think of anything else, I would be greatfull.
As for j.m@talk21.com, shouldn't you be in detention or something:rolleyes:

Why have I never had a problem with 14 or so K7S5A builds? :confused: I've used everything from 666 Durons to 1.7 T-breds.

Some rules:

1. Never power up the system when there's no heatsink in place. The K7S5A has no thermal protection and the CPU will fry in 5 seconds.

2. The power supply must be robust - not just adequate.

3. The memory must be top-quality.

4. The AGP card must be seated firmly.

5. The motherboard must not be tightened by a gorilla with a pneumatic screwdriver. :p

Remove the board from the case, place it on a soft, non-conductive surface near the case and plug in the ATX power. Place the vid card in and connect the monitor. Connect the power. Nothing else needs to be connected. Press down hard on the vid card and use your screwdriver to short the POWER BUTTON pins. See if it POSTs.

Already tried that. He got them at a computer show, same board and chip combo from 2 venders. Maybe its bad.

Computer show? Caveat emptor.

Upon close examination of "uncooperative" DIMMs like the one you described, I usually find they're just plain **** to begin with - remarked chips with dubious vendor names on them, questionable PCB design, bad chips that get sold as lower capacity gear to mask out the non-working areas, whatever ... you name it, I've seen it.

ok.
1. Make sure that everything is connected as it should be
2. move cmos jumper from clear to open
3. test the board by placing it on say a bed with just the power supply cpu+hs no case or ram and using a screwdriver to connet the power pins on the mobo as it may be the case switch thats broken
4. try diferent psu as that may be faulty


rik

I did that already, and a second time after I updated the bios.

[tricktx]

the only conclusion then is that the board must be duff. dont but from fairs

[Directive]

I told him that as well. I would NOT buy a MB from a fair or auction. NEVER.

[BipolarBill]

There are hundreds of thousands of K7S5As in circulation. The numbers would indicate that thousands of broken and defective ones are also "out there". Guess where they end up when the owner is less than honest? You guessed it. :(

[Peter M]

Hundreds of thousands? More like tens of millions.

[tricktx]

thats why there cheap. i as a consumer have the problem do i pay £45 for an ecs board which may be faulty but has a warrenty or a £100 board from a good manufactorer which i know will be bulletproof. and taking into account im 19 and self employed its always the k7s5a which i have bought 6 so far with only minor probems. But when the time comes and i have a fault a aint going to be mad about it.

[naf360]

a computer that does not post may have:

1. a toasted CPU (never forget to firmly secure heatsink before turning your computer on or else)
2. a loosely inserted RAM
3. a low psw
4. wrong cmos
5. incorrectly flashed bios
6. a loosely inserted GPU
7. a dead mobo

try checking them all out.
