Warp drive thrusters... Engaged!!

Great news, keep up the awesome work!!

I'm doing a little accumulating myself... I feel the news is coming, and the current prices @ under 60K is great

I believe the next rise will come when the actually release the wallet for us to use locally, and/or when mindfox releases his code. The wallet looks awesome and performs great!

Free coin pending... Who's gonna catch it first?!

I have a feeling we're gonna get some news soon... 20K CRYPT whale dumping on cryptsy trying to push prices down

CRYPT is still on coinmarketcap: http://coinmarketcap.com/crypt_7.html

I didn't open a github issue... but did put one out on the forum: http://coinmyne.proboards.com/thread/204/multi-algorithm-switching-sgminer

I've noticed now that not all of mine like the 1200/1200 clocks from that previous post... If one of my machines hangs with the settings below I've switched them to 1130/1400 clocks which all of them seem to be ok with. I don't feel like wasting the time to set the GPUs individually, lol. I've also changed thread & intensity settings since the new version with support for higher intensity was compiled. I now run:

rawintensity is the most basic of the intensity settings, it is just as is sounds "raw" and the very number used for intensity
intensity is the power of 2 to use... ie intensity: "15" is of 2^15 == 32768 rawintensity
xintensity is a multiple of the number of shaders for the specific GPU... ie xintensity: "512" is 1280 * 512 === 655360 rawintensity (for a r9 270 w/ 1280 shaders)


Many people (myself included) believe setting intensity as a multiple of shaders makes for better hashing

I previously posted these settings (https://bitcointalk.org/index.php?topic=623409.msg6951903#msg6951903) on my 270 x & non-x... getting 2.2MH/s each. From tweaking settings 128 gives better hash than 256... Although my w/u is only 0.03, YMMV. Also make sure to use the updated miner for intensities over 15 from page 13

I don't have a 280X... but I would say: drop worksize to 128, and gpu-memclock to 1500. I get HW errs on my 270's with really high clocks and have to reboot. If nothing else at least try dropping worksize to 128. Also I see you have shaders "0", I would either remove that or set it to the correct number of shaders

Love the new updated windows binaries from Elun! Getting 2.2MH/s (up from 1.95) now with my 270's (x & non-x) with the following settings:

Temps 60*C & lower (although I do have a 20" box fan under them)...

I'm rocking various (Sapphire, XFX, Gigabyte) 270 & 270X and am getting 2.05+MH/s!  Settings:


With previous software I was using 2 threads with other settings than above, but with the optimized x11mod  and after a LOT of testing the past couple days that's the "best" I have so far. I can push it faster but that seems to be pretty stable across all 5 of my machines (27 GPUs, > 50MH/s). If anyone has any better settings for 270's please pass along

I'm actually overvolting to maintain stability, but only +31mV per card... With my clocks/intensity like I have it, it's just low enough that it doesn't crash the system while mining. If I happen to lose internet connection the PC will generally lock up due to instability. I've never actually tried undervolting though so I might, it could just be unstable clock settings and not much to do with my voltage settings

Yea the reject rate is high I agree, but I think that is somewhat due to middlecoin, and yea probably somewhat due to my overclocking.  

Just double checked my wattage (at the wall with a Belkin Conserve Insight), at idle it pulls around 100W, after ~15 minutes of mining it was pulling ~1170W. So it's not quite as high as I previously stated, but still a lot higher than yours @ 1070/3 which is 358W. That's on a 1200W gold rated PSU (http://www.coolermaster.com/powersupply/silent-pro-gold/silent-pro-gold-1200w/), which states a maximum of 90% efficiency, but that's 90% efficiency at 50% load...lol. So lets say it's at 87% efficiency (but realistically probably less) since it's > 90% load, which would estimate that each GPU actually using ~311W

With all that being said, in GPU-Z sensors section it states the 290 cards are only using 245W each, so basically in line with what you're saying


I do have my target temp set at 85*C, from the factory the cards are designed to run at up to 95*C so I figured 10*C under that should be plenty safe... And allows more power that would be going to the fans to keep it under 80*C to go to keeping the clocks from throttling and/or more stable at higher frequencies... At least that's my thoughts on it


I actually used to use the eu server myself even though I'm in the US because I got lower reject rates. Only recently switched back to the main server b/c it was stated on twitter that: "All pool servers are out of beta. http://Middlecoin.com  now points to your closest server." I just switched back to the eu server to see if it's still better

Power consumption ~2400-2500W (2 PCs') at the wall including CPU & other mobo accessories (not including monitor). I'm really not too concerned with power consumption, I'm "banking" on the coin increasing in value making money over fretting over 10-20W of power savings because electricity is cheap IMO to the potential gains. For January my electricity "only" went up ~$160, I say only because it was dwarfed by the almost 2K worth of coin I mined

I'm mining mostly on middlecoin, so I think the reject rate is high(er) than "normal" due to that... But I haven't mined just LTC in so long there's no telling, lol. I do know when I started doing multi-coin pools the reject rate went up without changing a single setting.

This is showing the additional 2 XFX R9 270's mining, the power for those is not included in the above wattage, just the 6 R9 290's. It shows as only running for 15 hours due to an internet outage last night, with these settings and no outage it's ran for over 3 days straight without issue

Sure thing, here it is in all it's "glory" lol:




Thanks, I figured heat rises naturally so why not let it plus help it out a little bit more with a 20" fan! I'm building another 3 of these rigs this week (2 mobo's per rig, 5 GPU each), gonna change it up a little bit but same basic idea

I don't have 290X Tri-X... just Sapphire R9 290 reference. But here's some good settings, and perhaps a good pattern for them that could give good results for the 290X Tri-X

https://bitcointalk.org/index.php?topic=460181

I have 6x Sapphire R9 290 reference design using kalroth 3.7.2 with xintensity... I run all but 2 of them at 1050/1500 clocks, those 2 can only run engine up to ~1025 with good stability (and they get ~915+Kh/s), a few could actually run up to 1070 (which gets ~950Kh/s) engine clocks. Anyway with 1050/1500 clocks, xintensity 500, tc 20478 I'm getting 930+Kh/s 

Now some detail on where I came up with my settings:

I use "xintensity" 500 because it's just slightly higher than "intensity" 20, which I can explain:

• The raw value of "intensity" is 2 to the power of "intensity", so "intensity" 20 (which I previously ran) is a raw intensity of 1048576.
• "xintensity" is computed as a multiple of the number of shaders (2560 for my r9 290). So my "xintensity" 500 is raw intensity of 1280000.

Intensity explanation from the dev who wrote it if you'd like to know: https://bitcointalk.org/index.php?topic=87022.msg956792#msg956792

For thread concurrency I use 20478... I came up with this value by 2560 (# of my shaders) times 8 which equal 20480, minus 2. I'm not sure why the minus 2 seems to be the good spot, but if I use exactly tc:20480 it produces less hash rate. I tried multiples all the way up to 13 (tc: 33278) but anything over 20478 didn't seem to drastically help, so I just use 2 under the lowest multiple (8 in my case) of shaders that produced a good hash rate.

For my temps I set the target at 85, I have these 2 rigs (3 cards/machine) running in a spare bedroom (with a small fan blowing out of the room) and the temp in the room is usually 80*F due to the miners running but I do have a 20" box fan blowing directly on them. Needless to say the card's fans are usually at 85%+ due to the high ambient heat, I probably need to move them out to the garage to have more space to dissipate the heat generated.

If any of this helps anyone, any donations are greatly appreciated

Couple shots of my rig, I'm actually up to 9 GPU's in this frame now instead of the 6 shown... Sorry they're blurry, got bad lighting in the room
