Thought you meant mine as in yours. Didn't pay attention to the subforum. Mining isn't really worth it anymore.

I should be studying.

Very slowly. SO slow you will lose money because of your electricity bill going through the roof.

It's ASIC or bust now. Why do you think the prices of R9's went back to normal a while ago

For a slightly more useful answer than "don't bother mining" take a look at these.

 

Scrypt:

SHA-256:

https://en.bitcoin.it/wiki/Mining_hardware_comparison

 

I wouldn't recommed mining Bitcoin or even Litecoin at this point. If you want to mine another Scrypt or SHA-256 coin these could be handy, but I don't know of any reliable places to find out hash power for other hashes (such as X11).

600-750KH/s for Scrypt mining. Too slow for SHA-256 mining.

More like 800-900 KH/s a piece  :P

<Has Crossfire 290Xs.

It entirely depends on the actual specific 290/290X. That information is "optimal" imo. My 290X, with SGMiner (and CGMiner) would only do 700-750KH/s at most. There's not much of a different between the two (290 vs 290X) in regards to mining. In fact, I've noticed that most 290s do better than 290Xs at mining for some silly reason. 

Still, I would bet on the low end.

Seriously? I topped 900+ with my R9 290. And averaged around 875.

I thing it has something to do with the quality of VRAM. i.e. Hynix vs Elips-something or other.

If you attached them to a stick I'm sure they would not be durable enough to get you very far. Better off just buying a pickaxe.

Yes I made this pic just for this pun. I know I should be ashamed. 

muh specs 

Gaming and HTPC (reparations)- ASUS 1080, MSI X99A SLI Plus, 5820k- 4.5GHz @ 1.25v, asetek based 360mm AIO, RM 1000x, 16GB memory, 750D with front USB 2.0 replaced with 3.0  ports, 2 250GB 850 EVOs in Raid 0 (why not, only has games on it), some hard drives

Screens- Acer preditor XB241H (1080p, 144Hz Gsync), LG 1080p ultrawide, (all mounted) directly wired to TV in other room

Stuff- k70 with reds, steel series rival, g13, full desk covering mouse mat

All parts black

Workstation(desk)- 3770k, 970 reference, 16GB of some crucial memory, a motherboard of some kind I don't remember, Micomsoft SC-512N1-L/DVI, CM Storm Trooper (It's got a handle, can you handle that?), 240mm Asetek based AIO, Crucial M550 256GB (upgrade soon), some hard drives, disc drives, and hot swap bays

Screens- 3  ASUS VN248H-P IPS 1080p screens mounted on a stand, some old tv on the wall above it. 

Stuff- Epicgear defiant (solderless swappable switches), g600, moutned mic and other stuff. 

Laptop docking area- 2 1440p korean monitors mounted, one AHVA matte, one samsung PLS gloss (very annoying, yes). Trashy Razer blackwidow chroma...I mean like the J key doesn't click anymore. I got a model M i use on it to, but its time for a new keyboard. Some edgy Utechsmart mouse similar to g600. Hooked to laptop dock for both of my dell precision laptops. (not only docking area)

Shelf- i7-2600 non-k (has vt-d), 380t, some ASUS sandy itx board, intel quad nic. Currently hosts shared files, setting up as pfsense box in VM. Also acts as spare gaming PC with a 580 or whatever someone brings. Hooked into laptop dock area via usb switch

Trust me, i dont have an 290 but i know for a fact that those cards can mine 800-900 KH/s. If yours are slower you're doing something wrong, and you do NOT use Crossfire for mining, each card is separate.

Herp derp derp. 

I know I'm not doing something wrong. I literally tried every combination of settings in cgminer (then sgminer) trying to get more hash rate that I could. Obviously. I said I have Crossfired 290Xs. Then I said,

My 290X, with SGMiner (and CGMiner) would only do 700-750KH/s at most.

Which is obviously talking about a single 290X. 

You can trust me. I did everything I could to get hash out of my GPU. I went to IR chats, read documentation on cgminer, and cloned other successful 290X miners who got 850-900KH/s. 785KH/s was my max sustained average. 

From the time I spent on the IR chats helping people successfully start mining (quite a lot of time, particularly during the sudden rush of new miners after BTC dropped back down to $200-$300 range from $1,000), I found that 290/290X's were a mixed bag. Either you were like me (585-775 average), or you weren't (775-900 average), but it was pretty random (not 50/50, but close).

I spent about 10-12 hours a day in IR chats for 3 months straight. I helped people all day, just like you. and i never heard of a 290 doing less than 750 KH/s wihout the miner owner doing something wrong.

Cool. Maybe it was my lack of experience, but I had a unique experience relative to all 290/290Xs mining. To get mine beyond 585KH/s, I had to set -g to 1. Others had the opposite happen, where using -g 1 limited them to sub-600 KH/s numbers. Others could use --thread-concurrency 32765 while I was limited to 8192 for a long time then after not touching other settings, I could use ~25,000 but anything over didn't affect KH/s. 

Things weren't consistent basically.

*shrugs* I don't know. I've always been weird.

That's a weird case haha, never heard of that before.  I kinda miss spending time in that chat now i think of it :( It's been a while.

at current rates youll make like $10/month with your 2 290's (at most)
