Why do some S3's overclock and some dont?

[gt_addict]

Hi guys,

Just a curiousity question really. I have an S3 and an S3+ and the S3+ is overclocked to 250freq and has been since I got it. Runs fine only gets the occasional error on one chip every two weeks which a reboot sorts out. The S3 on the other hand wont take even the next freq up without throwing chips left right a centre or not powering a whole board.

Now to my question, why are they behaving differently? I know they are made at different times, and are technically different models, but has anyone tracked down or does anyone know why they behave so differently to overclocking?

Thanks.

the +  are better.

batch 1 and batch 2 were bad models they ran at freq 218 and freq 212. the did not do well

Not all S3+ are better. I have one that I use in my rig in my shed in the backyard, and it overclocks worse than my s3 that easily does 520gh/s with no x's. I used a 5000rpm pwm as well, so temps aren't that bad.
Some batches are just bad and you'll need to try to avoid them if you're buying old miners.

Batch 1 was bad enough everyone got partial refund.  Some ran up to spec but a lot did not.  To avoid this phil is right buy a + model and you should not have to worry about the really bad ones.

But S3's had a personality it seemed to me.  I always had some better then others and fined tuned each one.  But get a + if at alll an option over normal.

I had 40-50 s-3's pass through my hands   the majority were s+  and most did freq 237 easy  some did freq 243 and some did freq 250.

Some of the best mining gear ever made. 

although  avalon 4's were the best.   for my setup then s-3+'s

now I like avalon6 more then s-7

Thanks for the replies guys. I'm not looking to buy anymore but if I were I'd keep a look out for a + model and swap out my old normal one with wifi instead.

I'm along the same thinking about the personality side of things. Each one is different. But it still doesn't explain why though? Was it down to components used? Programming?

Cheers.

components and component quality


in mining with gpu's

in intel cpus


some clock great some don't

when chips are made they are not equal.

sometimes in gaming gpus you will read that the chips where binned.

Simply put tested and sorted by quality.

I think the s-3+ varied due to chip quality.

There are rare s-3++ machines that where most likely made with binned high quality asics.  These were sold mostly in asia.

That's fair enough. I was thinking if it was some kind of programming that it could be altered. Never mind. Thanks for the replies
