Re: ANTMINER S3 Discussion and Support Thread.

I see my coupons now .075btc x 3

when do they expire? expiration date is useful to know since it will give an indication when they will be available again for batch 4.

I predict there will be a big drop in price for batch 5, the reason is simple for batch 4 there are a lot of coupons for the people that did not want the refund which reduces the need for price reduction beyond the 7.7% for drop hash rate, and another 9% for difficulty increase, but as expected they will sell out quickly, for batch 5 all the coupons will be gone, and further increases in difficulty will force them to drop the price further, and by then mostly everyone that wanted one will have at least one, once they start selling from stock is when prices will be the lowest, just like it happened with the S1, history repeats. currently the s3 is the best deal for the money that I am aware of.

for me, validity time:

What do you recommend me guys then if i plan to run 2 S3 at 212,50 Frequency(~424,81 GH/s? - 362W / each, 724 W total). Use 1 corsair CX750W for 2 S3 with that frequency(212,50 - 362 W), or 1 corsair for each S3, and buy i dont know a 1000W new PSU for 2 more S3.

thanks

I recommend the antec hcp1300 platinum it is very good and has 16ga cables, a total of 10 pci-e connectors.
I have used it with 3 s1, and now using it with 2 s3, it can easily handle 3 s3.

But you can use it with 3 S3 as long as you dont overclock them, right? because with OC = 4x3 = 12 PCIE and you say it has 10 PCIE. I dont want to OC, i will just run it at stock frequency i suppose. Anyways, small changes in frequency requiere also 4 PCIE?? i mean whats stock frequency? 225??if i change to 237,5 i need 4 PCIE? thanks

well for overclocking all 3, you would need 12 pci-e connectors, so it would not be possible to overclock all 3 unless if buying the cables from some other source. but you could overclock 2 of the 3, and I am sure a moderate overclock in a cool environment will not be a problem with a single pci-e connector instead of the 2.
so it is possible to overclock 2, and 1 at stock speed.
