I hesitate to say yes. Not because I don't think it'd be great, but because I would hate for you to spend a lot of time on something that might not be rewarding.

I personally am looking at setting up some boxes at a new location with 7xxx series, not supported by bamt, and a quicky mine based linux would certainly be great, but if things fall through, with either the location or mining in its current form, I'd certainly be abandoning in a hurry.

So put me in for +1/2, as I'd like it, but I don't want you to knock yourself out over it

Especially if auction price starts > 2x the original price.

We've already passed the BTC price of the second auction 
Well, I'm still interested but it looks like prices are going to stupid places again.

Sounds good, have a pic of your unit? Hashing away would be nice too.

I heard that place is a madhouse on those sale days. Like black friday. Not worth the savings if you die.

 

Wonder where people get this soapbox. If it were always better, why would anyone mine?

I can't speak for others, but I started mining because it seemed "fun", not because it seemed like some sort of painful scheme that would make me rich. So I learned on the go, reading the forums, playing with hardware first hand, reading tons of stuff with lots of time. You can shortcut but it will ultimately hurt you.

There are rare occasions where blocks are "orphaned", in that someone finds a solution and broadcasts it, while someone else working on it finds a later solution before being "informed" of the existing solution, tries to broadcast their solution, but is rejected by the "real" blockchain, and loses credit. It's fairly rare though. Usually you'll receive an update from the network to switch to the new block.

Seems a lot of consensus on that point. Something worth trying. 7970s seem to be picky cards, tons of weird problems with them that vary from person to person. This might be one of them.

From what it looks like, and I'm not software expert, this is simply allowing pooled memory space, which I don't believe would have any impact on mining. Maybe it'll make scrypt a little easier to handle? Not sure, since you're still not hitting the CPU very much when your GPU is hashing away.

Card is likely defective, hence the PC shutdown. So yeah, RMA might be in order.

Just as an aside, maybe take the old manual peek to make sure the fans are actually running as they should be, and nothing is blocking them. You'd be surprised what the eyeball can do for you in terms of diagnostic troubleshooting.

Raidmax is utter garbage, and you don't need 730W for that rig anyway, so why not put the money towards a decent PSU of smaller size?

Silverstone 80Plus 500W is a good psu iirc, for like $55.

8GB of RAM is overkill for 7750s, and the sniper series is somewhat overpriced. Any old hum-de-dum ram is probably fine, maybe like 4gb of adata for $30?

That motherboard is really good, probably too good for a 2 gpu setup. Same with the processor. Now remember you're asking as regards a mining rig, if you plan to actually use this thing, then that's a different story.

As for the cards, they kind of suck for mining, you'll get maybe 120KH? I've heard the 7790 gets about 220KH, and costs only a lil bit more, so that might be something to look at.

Breakeven? no one knows, when BTC skyrockets, it might crash LTC. Currently 200Khash will get you like $50 - $70 / mo, so... assuming nothing changes (and it will) you'd maybe breakeven in 11months? Assuming 24/7 mining, and no elec costs.

Might be interested, would need some assurances of quality (super important component) by someone more qualified than myself (amateur PSU enthusiast) though.

Prices and specs also welcome.

I'm honestly a little confuzzled by all this ram and scrypt stuff.

I have 4GB on a machine, and running 3x7970s with CGMiner, they absolutely refuse to run with a thread concurrency above 18k. I looked back over the posts and ck says that he thinks it's a ram issue, and no other solutions have been offered. The cards run at lower concurrency, but at much lower hashes than I would like (something like 575KH/sec for a 7970 is poor) because of the subpar settings they are running under. They didn't have this issue when there was only 1 7970.

So be aware that more cards may yield more problems.

2 cards on power should be alright. Might be some funky-times with your dual PSU setup. If you have a kilawatts, check the wall-draw from the second PSU, I remember one fellow who had a dual set up similar to yours would find that all current was flowing through one PSU, and none through the other, even though he swore the cards were split between the PSU.

Lucky for those that have a 30A 240W line in their home. Unfortunately not so for this fellow.

I did find what seems to be a pretty good deal, looking at the fellows quote above. 2 Full Cabinets, wired with 15A of 240V (208V obv usable) each, unlimited 100mbps internet, 24x7 hands on tech, for $1100/mo, with no setup fee. Looking like datacenter is back on the table wewt. Now I just have to figure out how I would remote admin all that nonsense.

I saw it, it doesn't really help me however, as I mentioned power is my big downfall. That thing would just trip all my breakers and probably burn my house down. Not entirely sure who could run that thing at full capacity either.

ty for the info, always good to have comparisons. I suppose though that pricing is dependent upon usage? I found some pretty good rates, however the big killer seems to be that for colocation people expect you to be there for a while (else a large set up fee), which makes no sense if I'm just looking for a quick flash in the pan. C'est la vie.

Is there a way to try to pester the admin other than the forums which he doesn't seem to read?

Sorry but there is just no way to get a reasonable estimate.

Avalon has delivered 1 batch, batch 2 is nowhere in sight, no one knows what the status is. Batch 3 will be affected by batch 2, etc. In fact, that's part of what made me reconsider an ASIC chip purchase from avalon. Either way is kind of not good, if their batch 2 is delayed, and their chips ship on time, that's pretty shady for batch buyers, if batch 2 is delayed, and chips are delayed, then everyone loses.

ASICMiner is a big question mark. They've sold off about 60 * 10GH/sec miners (600GH) for a ton of money, whether that prompts them to reinvest into making tons of miners, selling more, or keeping supply low while demand is high, is anyones guess.

BFL is the biggest question mark of all, no one knows how many orders they have, how many refunds are waiting, what their production capability will be (currently they don't even have cases for their products, let alone boards).

We could roll around into August and see a tiny nudge in difficulty (if batch 2 is on the streets, it'd be about 25mil, if batch 2 + 50TH appears from ASICminer maybe 50mil), or if everyone unleashes the kraken, we could see potentially 150 + 100 + 200 + 250 TH added on to the network, which would be about 100mil. The only way we see 500mil is if some magical pixie dust super energizes every ASIC maker, BFL included, all the "up and coming" asic makers turn out to be able to produce and ship a product in 2 months, and new asics are priced at $1 / GH, shipping that day delivered overnight shipping. (500mil is roughly 50x current difficulty, or 3,500TH/sec, almost impossible by August, requires about 2000 BFL minirigs to be delivered).

Seems to be an old unresolved issue from earlier, with some machines with less ram apparently. Guess no scrypt for me, thanks anyway though.
