You build the open air case there?
The risk to Ltc is the flood of coins being mined and sold to pay back the equipment of new miners. Will probably drop ltc value like a rock. Difficulty should spike also. If you are starting now, I'd say use what you have.
Or value will keep rising, who knows with this stuff!!!
Here's my take, and this is as someone who is mining LTC.
IMO it's honestly a big bubble, LOL @ anyone who says differently. It will burst and my guess is that there will be another bubble within 6 mos - 1 year, here's why:
- Litecoin halving should be in 2015, relevant for below part.
- LiteCoin ASICS *are* coming: http://www.coindesk.com/asic-miners-litecoin-soon/ ASICs cost big bucks. They will take over the LTC network just like they did the BTC network. These "investors" will want to "make" their money back, couple this with the fact that ASICs for LTC will be out before the halving (unlike BTC) means that ASIC owners will be in control of a larger percentage of LTC than they are with BTC. They will artificially constrict supply to drive up prices.
- Also, MT.Gox is (slowly) working on adding LTC as the second currency to their exchange. Even if it sound ridiculous, in the crypto-currency world, that's like being listed on the NY Stock Exchange. It will give LTC "cred", deserved or not.
Personally, I just cashed out some crypto, and bought a few more cards and enough funding to power them for 10-12 months. Even if I'm wrong I'm "up" the hardware and even on the power... but if I'm right... it will be a good day (for both me and Uncle Sam).
----------------------
Currently mining with:
1 x 280x
1 x 6950 (unlocked)
2 x 5830
3 x 5770 (adding 1 more)
I've been having good luck running most of the cards heavily undervolted at close to stock clocks. Keeping temperatures / power draw in check. On the 69xx/58xx servies I see to get the best results with a .85 core/memory ratio. On the 57xx I get the best khash at 0.75 ratio. I actually get lower k/hash by increasing one or the other and losing the ratio, more so with the 5000 series cards though.
280x I'm still experimenting with (arrived today) - getting ~600k/hash now.
6950U - 765Core/900 memory @ 1.049V - 395 k/hash (~140w power draw 2.82w k/hash)
5830s - 780Core/920 memory @ 1.070V - 280 k/hash (~115w power draw each - 2.43w k/hash)
5770s - 880Core/1180 memory @ 1.000V - 208 k/hash -(~80w power draw each - 2.6w k/hash)
Power draws are estimates from a kill-a-watt, Total full system power draws (without the 280x) was 740Watts. I haven't measured with the 280X yet since I don't have it tuned yet but I'd guess it would add another 300 watts total draw (it's in it's own box), the other cards are split into two systems. Older 5000 series cards are a greate way to go for mining still. The cost per k/hash is low (about half of a 79xx series card) and undervolted they are still fairly power efficient.
I think LTC bubble should pop relatively soon. I actually cashed in some coins also and have 2 more r280x cards coming to add to my venerable 5870 & 5830. I'll test some .85 ratios thanks! I get 280kh on my 5830, but at 850/1000 which is quite a bit higher. The 5870 at 407kh is still in a league of it's own (can reach +/-440 with a bit of juice). Hopefully can squeeze a bit more than 600kh per 280x, I'm aiming for at least 725 per card. If the scrypt ASICs get closer to release I'll probably grab a couple, but so far they are still promises & vaporware a la "Butterfly Labs". Depending on difficulty scaling maybe I'll build another mining setup, need time...
So my question... I only have a 650w power supply... do you guys think that would be even remotely close to enough power to leave the 6950 in with my 290? If I underclocked the 6950? I assume it would be worth keeping them both in if I can make it work.
Is that how efficiency works ? I thought it met that to if its efficiency is 80% then if the computer needs 80 watts, the psu needs 100 from the wall

The last time I checked, a good psu is approx 90% efficient.
However, psus are rated by their output ratings. Thus, they will draw more from the wall than what they show.
I'm running four 950w PCP&C psus that show I'm pulling about 1030-1050w from the wall using a low quality kill-a-watt meter. They've been running stable like that for 7 months.
Most PCP&C units, because the design is a lot older (2006 ish I think), are a bit less efficient, around low 80s % at high load like that, especially on US voltage. At 1050W AC from the wall, you're probably pulling 850-900W out of the unit at best. They're pretty well made though (again, the original ones, can't speak for the newest ones with OCZ influence) so they should cope fine.
Network difficulty has increased from 1500s to 1900+ in the span of five days
Anyone else notice nearly all the 7950, 7970, 280X, 290 and 290x are sold out on newegg.

This is making me happy, since people are now tossing their "outdated" NVidia cards..
Has anyone tried middlecoin? I'm not sure if it is really worth it. I made about .899 LTC in ~1.5 days or so, and only got .019 BTC after about 32 hours or so. I guess it's a bit easier since I won't have to convert in BTC-E to BTC and then transfer back to coinbase, but still. I guess I'll give it 7 days and if I don't like it, back to LTC mining.
I've been using it for the past 2 months. I've had low days of .002 to high days of .021 on a single 7950 on middlecoin. All depends on how much they exchange for BTC on any given day.
Oh alright, that's kind of what I thought. Is the hash rate on there correct? cgminer tells me 1.145 mh/s, but I constantly get less on the website.
I can't wait to see AMD's 4th quarter reports after this, out of stock everywhere
We should start an [H] pooling for litecoins.
