Which pool do you suggest as a backup? As I have only about 500 MHash/s I want pool with small minimum payout.

If the price you paid is unknown or unreasonably low, the customs can calculate the "market value" and use that for VAT. And the chips are worth more than nothing, but who know how much...
I think it depends on what value will Avalon declare. It should be less than what we paid, but not too low for customs to be suspicious (although the majority of standard SMT chips and components are less than $1).
Also the customs sometimes tend to "guess" the price from the size of the package, so small box full of expensive chips declared as $10 won't be suspicious, but big big box with something really cheap would be

They did just notify Sebastian that he should send their chips to burnin once they will arrive. But they will also have to arrange the order with burnin when he launches his website.

Yes, it is estimated to be 19.3M and will rise after 110 blocks are solved from now.

Block when difficulty will rise: http://blockexplorer.com/q/nextretarget

Or you can see it in graphs at my webpage: http://btc.marki-online.net/

Burnin, do you think 12v 15A power supply will be fine for 3 boards?
Your specs say each board with 20 chips will draw approx. 40W, that is 3.33A @ 12v, so for 3 boards it would be exactly 10A, so 15A power supply should handle it fine... I was thinking about something like this: http://www.ebay.co.uk/itm/DC-12V-15A-180W-Switch-Power-Supply-Driver-For-LED-Strip-Light-Display-220V-4-/200725152098?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item2ebc26c162

Sebastian, how were the sample chips marked on the envelope? What price (and description) did Avalon declare?
I'm wondering in how big (and heavy) package will those 10.000 chips arrive

Anyone using pool.itzod.ru? It doesn't have any fees...

I am using bitcoin.cz at the moment, but as it has exponencial payout based on the last submitted shares, I'm not sure if I won't earn more in different type of pool (for example PPS - pay per share).

Hi all,
What is the best BTC pool and payment type (PPS/PPLNS/...) for low hashrate of 400 MH/s?

Don't forget that burnin will get sample chips also from other group buys, so he should have enough for one XX miner.

Good idea Although when batch 5 sample chips will arrive, we should hopefully already have batch 1 fully shipped, so they won't be useful for development - only as few free pieces for those who ordered many chips.

I'm not sure if I understand what Moneypak is... is that some kind of printed code which you can buy at local store and then use it on their website? Is it available also for non-US people? Will you be able to send the money to my Paypal account? Or does MP do some kind of verification of target paypal accounts? And finally, what is the minimum amount of USD? Thanks

I have one 5770 card (default 850/1200 clocks) on which I was trying to mine litecoin in my home computer and then moved it to a HP server in datacenter, however there I can only reach about 60% of performance, but don't know why.

At home, I had Windows 7 64bit, 4 GB RAM, cgminer 3.1.0, latest AMD driver and SDK and card in x16 PCIe 2.0 slot. With TC 3968 (more TC was not working) and intensity 18, I was getting about 200 kHash/s which is good for this card.

On server, I have 64bit debian linux 6.0 (squeeze), but only 3 GB RAM and the PCIe slot is only version 1.0 (x8 using a riser). Cgminer is also 3.1.0, driver 12.10, SDK 2.8 (I followed this guide http://www.scribd.com/doc/132505278/Debian-GPU-Litecoin-cgminer-install-guide ).

I was trying various TC and other options, intensities 12-20, but can't get more than 117 kHash/s. What was different is that I was able to compile bin with more TC (even more than 5000), but it had no effect on performance. Even OC didn't have any effect. Bin files for Windows had "l4" on end, those on linux have "l8". From documentation it is "size of long". Does it matter in something? Can for example linux cgminer use bin file prepared on windows version or is it incompatible?

What could be causing this?
1) Maybe is the PCIe 1.0 the bottleneck? How does scrypt mining work? Does cgminer transfer huge amounts of data to GPU memory? Or mainly the GPU itself does majority of GPU memory accesses?
2) Or only 3 GB of system RAM? But cgminer is using only 300 MB of RAM, which should be OK for just 200 KHash/s... I have read that scrypt mining needs a lot of system RAM. How does it use it? For some pre-computations or does it transfer the data to GPU memory?
3) Or is it just bad combination of driver/SDK versions?
BTW bitcoin performance is OK on the linux server (about 195 MHash/s), only scrypt is affected.

Hi burnin,
what about the pre-calculation mentioned in the ASIC datasheet (section 4.2)? Isn't their FPGA doing that? Or cgminer does that automatically? I'm not sure how difficult is to compute that for each ASIC when it is doing 300 Mhash. I don't see the nonce mentioned there, so probably only one pre-calc is needed for each chain of 10-20 ASICs?

Nobody?

Which of the thin wallet clients (those which don't need to download whole 7+ GB blockchain) do support message signing? I have tried Multibit so far and it doesn't...

Too bad I didn't know about those 4 hours before registering... I was reading the forum for 2 days as a guest
