Guys,

I have updated windows miner. Now it detects (does its best to) AMD OpenCL platform and uses it, and has some memory config detection improvements. Please redownload from the same place and report any further problems you may encounter.

Hi,

Firsty, great work reorder! Excellent miner.

Do you know what is the windows 7 x64 default GPU_MAX_HEAP_SIZE, becouse i entered 95 like I sow in this thread and lost about 2 HPM-s on both 280x and 290 cards. Both were running at 20 hpm and now 18.

I cant find the old heap size, tried everything, please help.

Thanks

This must be statistical fluctuations, as I have hardcoded setting GPU_MAX_HEAP_SIZE to 95 (100 in the upcoming version) in the miner and global envvars have no effect on it.

a gpu miner for nvidia? for CUDA?

Not yet, maybe in 2-3 weeks.

Reorder - My AMD card is on platform 1, I have a nVidia on platform 0.  How do I get the miner to recognize the card on platform 1?

Thanks.

Too bad, I have it still hardcoded to search platform 0 only. Will fix that tomorrow (I am in European timezone), sorry for the inconvenience.

Any news on this update?
I have 200 GPU's ready to go but they are all on platform 1.
I don't feel like setting up all rigs from scratch to get them to platform 0 so I'm desperately waiting for this update

I am working on this atm, I figure the fix will be ready in ah hour or so, stay tuned!

Guys, please provide your input in performance topic: https://bitsharestalk.org/index.php?topic=1803.0

We need your data to work on further miner and pool improvements!

I downloaded the GPU client for windows. Seems to be clear: http://virusscan.jotti.org/en/scanresult/b9b350315051de4c55abb4ca5bda03170613b91d/44c2893c0e9eb888b5a5dc062582202460a31a82

My hashes are:

sha256: a5ba37d01f2170824a8be52fbf7589a76c4ef00fd282b04557f7bd389ca5742f

md5: a26cb33038b04c344011bd08e7f7246e

are they correct?

@1gh: Please provide hashes for all downloads!

I will ask 1gh to add them indeed, but only after I am done with bug fixing. So far it is a moving target, do not rely on these hashes. Hashes also make only so much sense as you are downloading from our own site and not from some filestorage that could be compromised.

hey reorder,

anything I can do with the high rejected/timeout rate?

http://gyazo.com/b9e4154cbcaf62f6502345eaf9e394cb

Rejects must be hardware errors on your card (the pool does not find block as often as to cause many stales), maybe it is due to overclocking?

I have checked, and there is no reason for timeouts too, the pool is not currently overloaded or under ddos. Does you hashrate displayed on the site match your hashrate in the miner? If yes, then timeouts are false negatives, nothing to worry about.

I'm using laptop and haven't OC'ed. Yesterday my hpm (shown in the miner) was over 3.5 and now it's under 2.5. I'll also noticed my fan isn't spinning as fast as usually. I guess I'll try reboot if that fixes the problem.

hpm on the site goes from 1.5 to 5.5, should I call that a match?

Well, 2.5 falls in the range

I am trying to run the miner on linux but I am getting the error below:

Tue Dec 31 10:44:50 2013 Miner Starts - mmcpool.1gh.com:8080
MC2Hasher:0 initialized on device: Tahiti type: 4, vendor: Advanced Micro Devices, Inc., mem: 2147483648 with 1-pass algo

LogicError: create_buffer failed: invalid buffer size

I don't quite understand what is wrong. Any suggestions?

Looks like a bug in Linux miner (it should have chosen 2-pass algo with this card), will fix it.
