Woe is me... AMD... A7V

[Dyflam]

I received my A7V and Duron 600... that's the good news. I soldered the L1 bridges to unlock, installed the generic heat sink and fan, video card (TNT2 ultra), 1 stick of PC100 Kingston value ram (128MB), set jumpers to default, and voila... no boot. Changed jumpers to 100MHz FSB X6, 1.75V core voltage, power on... repeating high tone, low tone post code. Book says bad or missing ram. Replaced ram w/generic PC100 stick... no change. Tried ram in all 3 slots, no worky... Suggestions please...

You soldered the bridges?... Did you make sure to keep the solder separated? Each individual bridge is supposed to be connected. If you connected them all to eachother, then you will want to take off all that solder and maybe just try a pencil to connect them. Make sure you only connect the L1 bridges. Besides that, try using the default settings for the cpu and ram and see if the chip will boot at those settings. Hopefully you didn't burn the chip. I have to admit though, you are one brave soul for soldering your duron.

Thanks for the feedback MOOT. The solder connections are good (no shorts between bridges)and my initial attempt at power up was using default settings.

How did you manage to solder to BRASS !!

I don't have your setup, but I would guess something went wrong with the solder job, maybe. Try a different processor.

 

[Dyflam]

DaddyG, I think those bridges might be gold. They seemed to accept solder ok.

Classy, I don't happen to have an extra processor but as a last resort I would probably purchase another one and in hindsight I should have tried it before I modified it.

Thanks for your help.

It might be the memory. The A7V may not have autodetected your memory and may have choosen incorrect settings. I've heard of this happening before to people who have tried using budget memory.

I'm using generic pc-100 memory. If you think memory errors are the problem, set the bus speed to 100/133mhz via the jumpers.

 

[Dyflam]

I appreciate the advice everyone. I'm still struggling but have a few more things to try before I give up. I'll let you know how it turns out.

Thanks again

All is OK. Duron 600 @ 800 running a little hot (65C) but no lock ups yet. What a serious pain in the butt to set up!!

65 c is way too hot.....you will want to try to keep the cpu temp below 50 c at all possible mean...
