I would also like to hear from anybody a bit more reputable who has experience with this company, though the fact that they put everything behind a registration wall seems pretty scammy.

If you are going to stick them all in a standard case and you are worried about size you may want to consider the 750Ti's simply for the heat factor. Also 1500w is way, way overkill for a 3 card rig regardless of which you go with. You could get away with a 600w with the 750s and 850w with the 270s.

I love the site and have been using it for 6 weeks or so, unfortunately I have been running into a debilitating error the last couple of days. Most of the time I click the calculate button it loads a server error page that reads: "We're sorry, but something went wrong. If you are the application owner check the logs for more information."

Awesome, keep the updates coming. I noticed that you can include the CPU in the list of devices to be used with your miner, is this efficient?

It seems to be all over the place but I saw as high as 29000kh/s but consistently around 15900kh/s till it starts going down. Granted, that is for two 290s.

Any idea why the miner seems to just stop finding shares after a while? I noticed the kh/s going down over time but it was still finding shares pretty quickly, but this morning it was reporting 0 kh/s and not finding shares. Win 7, R9 290 if that helps.

Here is the virustotal link for the dropbox: https://www.virustotal.com/en/file/af246e2ec5d054ac8d8892170ac5ec8cdcdc4b6b6949986f446ad24379c87cb0/analysis/1391476523/

Looks to be clean, so I'll check it out.

I'm interested. This is certainly different.

I'm currently running one of these at 1030 core/1500 mem using sgminer and getting 920kh/s. It hovers around 70C at 70% fan speed. You could probably lower fan speed and let it go up to the 80s but like it to stay cooler and use the MSI Afterburner custom fan curve. I should be receiving my second one in a few days.

Thanks!

I may just take you up on that. Now xiv.coinworld.us is saying they are shutting down.

Just a heads up for those mining at http://xiv.coinworld.us/ Check your donation percentage. In the middle of the night it "suddenly" went to 2% on its own. You don't get to charge a fee and the force users to "donate". Otherwise I've had no trouble there, but I won't be mining there anymore.

Axio, my bad, I appreciate the response but I totally noobed out on that one. Apparently the payout was set to 500 coins and almost every transaction to my confirmed pool was that much or more so it was going straight to my wallet instead of confirmed. It just looked liked coins were disappearing from my unconfirmed meter... as soon as I opened my wallet the coins came pouring in.

If you've recieved payouts from xiv.coinworld.us, can you explain to me why after 150+ confirms it seems like blocks are disappearing and so are my coins? What are the minimum confirms for Xivra to make sure the block is yours? As I assume (though maybe incorrectly) that the 600 confirms is just for maturity.

@OP I'm running the non FTW version of the EVGA 670 and if I overclock my card or use the new autotune suggested kernel I get a crazy amount of rejects.

Currently running the k14x16 based on the old autotune suggestion with stock clocks and getting 215ish kh/s, trying to figure out how to push it more without upping the rejects, any ideas from you tweaking your cards?
