SST chips no good or is it just me
 

I've been trying to use the SST 27SF512 chips from Xenocron and three out of three are giving me errors... are these simply bad chips or what? ::) I'm using willem btw.
Am now on the lookout for some AT29C256 chips...

Re: SST chips no good or is it just me
 

Is your offset set correctly?

Re: SST chips no good or is it just me
 

yeah you' re just doing it wrong.

i had two bad chips from xenocron not long ago as well, bought two from moates and problem solved... maybe he has a bad batch or there getting damaged during shipping somehow

now even with the new chips it doesnt matter what changes i make to any map, idle is uber rich, and above about 3000 its lean as hell

Re: SST chips no good or is it just me
 

strange, ive purchased a good 4 sleeves of SST chips and haven't had a single bad one yet.

Re: SST chips no good or is it just me
 

yes, 8000

I was able to program one, but after a couple of times it crapped out. I'm thinking the AT29c256 are more solid/reliable

Re: SST chips no good or is it just me
 

they're also more discontinued.

personally ive burned and re-burned more SST chips than i can count, without ever having a problem. I don't for one second doubt their capability or reliability

oh, and im also burning with a willem.

my barrowed willems doesnt like sst's at all, i use 29's and its fiine

Re: SST chips no good or is it just me
 

I use both on a regular basis without problem. the offset should be 080000. But you had burned one in the past, so that probably isn't it.

Re: SST chips no good or is it just me
 

are you changing the yellow jumper and erasing them properly before each burn? and watching the erase process to make sure the progress bar doesnt start over at all?
