Yeah, you nailed it - I just couldn't see it until the numbers hit me in the face. Thanks!

Mining & Pools / Re: Intensity change on one card affects both cards' hashrates dramatically
« on: December 26, 2013, 07:06:12 PM »
Resolution!!!
Thank you for the suggestions which led me down the path to discovery. Turns out the guides are incomplete (imagine that!) Here are some findings:
1. Just because a rig will run and cgminer shows both cards as being used, it may be a lie (like cake).
2. If you have two cards (possibly more, someone else will have to verify this) which seem to balance the expected max hashrate for one, and their hash rates flip flop when Intensity is adjusted, it probably means only one card is being used, but the stats are for both. This is a tip-off that something is astray.
3. If one card has high temp like 70C while the other is low like 38C, that's another tip-off that one card is not being used.
4. If you plug a monitor into both cards and then fire up cgminer, both cards get recognized and used, my current numbers with the settings as above without any tweaking are now 544 kh/s for GP0 and 570 kh/s for GPU1. Point here though, is once cgminer is cranking along, you can remove the monitor cables from the rig and both cards still get used as they should. I will get dummy plugs, but for now the cards only need to be plugged in to start cgminer, so it's not really a big deal.
I hope this helps someone else down the road and thanks again for the help from the GoldCoin community!

Ok,
Mixing and matching, all results after letting hash rates settle for a couple minutes, here goes my journey of discovery:
Yanked one card and running only one (in slot 3) gave these results:
GPU 0: 66.0C 2978RPM | 576.9K/582.3Kh/s | A:3516 R:0 HW:2 WU: 537.7/m I:19
So, lets call it G1 is 576 by itself..
Other card (G2) by itself, slot 3:
GPU 0: 66.0C 2812RPM | 579.3K/579.9Kh/s | A:1174 R:0 HW:1 WU:509.1/m I:19
So they both can do ~575 kh/s each by themselves......
I plug the other card in, this time in slot 2 (to avoid slot 1) so both cards are in and in different slots than before, and results are the same:
GPU 0: 67.0C 2784RPM | 303.6K/295.0Kh/s | A:772 R:0 HW:0 WU: 286.6/m I:19
GPU 1: 29.0C 9999RPM | 288.1K/295.0Kh/s | A:794 R:0 HW:1 WU: 286.6/m I:19
So, what, I need a Mobo/memory/chip for each card? That is ridiculous, something isn't right.
Any ideas?

I swapped card slots and the numbers are still the same:
GPU 0: 69.0C 3320RPM | 309.3K/300.2Kh/s | A:1092 R:0 HW:0 WU: 289.1/m I:19
GPU 1: 30.0C 9999RPM | 291.7K/297.8Kh/s | A: 862 R:0 HW:0 WU: 254.8/m I:19
Maybe it's a bad card slot or mobo issue. Going to try just one card in each (of 3) slots and see what that provides.
--paaco1981 - your response just popped up while writing this - no real change, I'm going to try one card at a time in all 3 slots (sounds dirtier than it sadly is.......)

Oh, and both cards are getting accepted shares at about the same rate, so it's not like that low temp card isn't working.

tadspoles ~ I used your settings and allowed it to settle - numbers were lower. Increased intensity slowly and maxed out at pretty much the same numbers I posted.
paaco1981 ~ Yes, the temps are curious, but they are both on the motherboard and the higher temp one has fans feeding off the back of the other card. I will swap them and test that, then add the risers to each which I have but had not installed. I'll post numbers in a little bit.
Thanks for your help and suggestions!

Mining & Pools / Intensity change on one card affects both cards' hashrates dramatically
« on: December 26, 2013, 12:24:57 PM »
Hi all,
I have 2 Gigabyte R9 280x (GV-R928XOC-3GD REV2 R9 280X) cards which should each be pulling ~ 700 kh/s but their combined hash rate shown by cgminer is ~602 kh/s. For best results, both are currently set at Intensity 20 and they run fine at about 300 kh/s each . If I change the intensity of GPU0 down to I19, the card with I20 races up towards 400 while the one at I19 drops toward 200 -- effectively keeping the combined hash rate at 600ish. If I swap intensities, the same thing happens with the numbers reversed. Any idea what is keeping the combined hash rate around 600? How can I get them to each to run at 600+ kh/s each?
Setup:
Motherboard -- ASRock 970 Extreme4
Processor -- AMD Sempron 145
Memory -- 4GB G.SKILL DDR3 SDRAM (2 x 2GB)
Power Supply -- Seasonic 1000w Platinum PSU
GPUs -- 2 @ Gigabyte R9 280x (GV-R928XOC-3GD REV2 R9 280X)
OS -- Xubuntu -- uname -a says: Linux box1 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Screenscrapes:
As for the number of HW errors in the scrapes below, note that this is after it's been running for 48+ hours -- don't think that's a high number, but chime in if you think it is. Also, notice that GPU 0 is at about a third of max RPM while GPU 1 is always at 9999. Not sure if that makes a difference.
Running with both GPUs at the same I20 Intensity level:
--------------------------------------------------------------------------------
GPU 0: 72.0C 2755RPM | 334.4K/300.0Kh/s | A:681268 R:3472 HW:17 WU:275.7/m I:20
GPU 1: 42.0C 9999RPM | 285.3K/301.0Kh/s | A:675573 R:2393 HW:23 WU:282.4/m I:20
--------------------------------------------------------------------------------
If I change GPU Intensity: GPU0 @ 19 and GPU1 @ 20 and let run for 5 minutes:
GPU 0: 72.0C 2854RPM | 204.2K/299.6Kh/s | A:683744 R:3472 HW:17 WU:275.3/m I:19
GPU 1: 43.0C 9999RPM | 404.1K/301.3Kh/s | A:678255 R:2393 HW:24 WU:281.9/m I:20
Switch Intensity so: GPU0 @ 20 and GPU1 @ 19 and let run for 5 minutes:
GPU 0: 72.0C 2657RPM | 397.1K/299.8Kh/s | A:686014 R:3472 HW:17 WU:275.4/m I:20
GPU 1: 42.0C 9999RPM | 201.3K/301.2Kh/s | A:679700 R:2393 HW:24 WU:281.7/m I:19
Command line:
./cgminer --scrypt -I 20 --shaders 2048 --thread-concurrency 21712 --auto-fan --no-submit-stale -o stratum+tcp://xxxxxx:3333 -u xxx.1 -p x
I have tried numerous things from several online guides to overclock, over mem, etc, but everything I tried lowered the hash rate from what you see as the first screen scrape. Something is clearly not right but I cannot figure it out. Any help greatly appreciated.
Thanks!

Service Discussion / Cryptsy having issues with deposits again?
« on: December 12, 2013, 06:29:56 PM »
I've bought bitcoin at Coinbase several times and transferred to Cryptsy to purchase GLD. Today Coinbase says the transaction is now complete and confirmed (was pending for well over an hour -- another GLD selling point, the speed). Over half an hour after that there is still no recognition of the transaction on Cryptsy. Is there a deposit issue there again? I know there was one a few days ago but thought that was resolved.

Newbie Central / GoldCoin Paper Wallet (how does that work?)
« on: December 12, 2013, 05:40:09 PM »
I've gone the site http://goldcoinwallet.com/ which allows users to generate new GLD wallets and print both the wallet address and the private key for the new wallet. There are no instructions on the site as to what to do with said printouts. I can see that technically I can edit the config file of my GoldCoin client to set the wallet values to what is on the paper, but that seems too tech-rogue to be viable to the masses. So how do I get the QR codes or the straight-up address/private key pairs into a wallet (new or existing)?
Let's break it down: My kid downloads the GoldCoin client and he installs it correctly on his computer. I create one of these paper wallets (I have no idea what the "brain wallet" option does), and send 100 coins to the address on the paper. How does he associate the paper wallet with his client/wallet and get those coins into his wallet?
Any assistance appreciated.
