Z87-G55 confirmed to work with 7x R9 290 (using modded driver from https://litecointalk.org/index.php?topic=11761.0) with Windows 8.1:
What kind of risers you used? This mobo can't work with x1 risers in the x16 slots. Doesn't it?

...

The only way is use the x16-x16 risers?

Using all x1-x16 except main GPU (first x16 slot).

Getting some blackscreens sometimes though, either when shutting down, booting up or closing the miner. Can't figure out why yet.

z87 g45 confirmed working with 7 R9 280x cards. z87 g55 and z87 mpower should work fine too.

Rig config :

- windows 8.1
- lbr modified 3.12 amd drivers
- All cards on 1x 16x usb risers.

z87 g45 don't have 7 pci e

btw what is the best card with 6 pci e slot? i don't need the risers, i'm planning to do a different kinda of mining

Pretty sure it does have 7 PCI-E, both the MSI official page as well as the pictures of it confirm it:

Currently each card seems to pull a max of 25-30W per PCIe out of the board + 240-250W out of the 6/8 pin power connectors, measured at the wall. Temps are 75-85 while mining at about 810 kh/s (underclocked core clock to 900/1250).

Currently doing 3 Sapphire R9 290 Tri-X on all 16x slots due to lack of risers with no problem. Hope to get some within a week.

Actually in the case of the MSI Z77A-G45 it's a hardware limitation, confirmed by MSI (check details in the link posted next to the board's name).

I'm looking to build a 7 cards rig and I'm quite conflicted about what mainboard to get. There's scarce information about this as people usually try to limit their rigs to a maximum 6, so I've decided to make a short list of what I found on the interwebs during my research:

Working:

MSI Z77A-GD65 - link: https://bitcointalk.org/index.php?topic=186877.msg2206520#msg2206520

ASRock Fatal1ty Z87 Killer - link: https://bitcointalk.org/index.php?topic=36061.msg4369450#msg4369450


Not Working:

MSI Z77A-G45 - link: https://bitcointalk.org/index.php?topic=97154.msg1069726#msg1069726


Unknown:

MSI Z77A-GD55 (probably not working, configuration similar to the Z77A-G45)
MSI Z87 Series (GD65, MPOWER) (probably working, configuration similar to the Z87-G45 Gaming / Z87-G55)
MSI Big Bang XPower II (X79)
ASRock X79 Extreme11
Gigabyte Z77X-UP7
Asus Z9PE-D8 WS


If you have any information on any of these boards or any other 7 PCIe boards, please let me know.

Hope this has been helpful for people looking for the same thing as I am.

Seems running scrypt-jane on Windows performs worse than on Linux. I'm getting max ~1.8Kh/s in Windows as opposed to ~2.3Kh/s in Linux with same hardware. Is this to be expected?

Can't seem to compile latest git clone. I run ./autogen.sh (which doesn't output anything), ./configure then make, and I get the following errors:

Code:
nvcc -g -O2 -Xptxas "-abi=no -v" -arch=compute_10 --maxrregcount=64 --ptxas-options=-v -I./compat/jansson -o salsa_kernel.o -c salsa_kernel.cu

salsa_kernel.cu(742): error: more than one instance of overloaded function "cuda_scrypt_core" has "C" linkage

3 errors detected in the compilation of "/tmp/tmpxft_00004701_00000000-6_salsa_kernel.cpp1.ii".

Any ideas on fix?

Re: Gridcoin (GRC) - first coin utilizing BOINC - Official Thread

Hey!

Been playing around with Gridcoin, my first attempt at mining cryptocurrency, and I found a bug with the cgminer instance config generation. I described it over here and will try to summarize it:

Here's how the configuration panel looks in gridcoin-qt:

http://i.imgur.com/3IjiHHP.png

After creating the cgminer instance, cgminer wouldn't start. Here's some info:

Code:
cgminer.exe -c cgm0 -T

 [2013-12-29 23:33:23] No known USB devices

After doing some research, I fixed the problem by manually changing the "gpu-platform" setting in cgm0 from 0 to 1.

Hope this helps anyone else having this problem and that there will be a fix in the config generation in an upcoming version of Gridcoin (recreating the instance sets the setting back to 0).

Oh and happy new year!

[SOLVED] First-time miner, can't get Gridcoin mining to work
by

on 29/12/2013, 20:27:24 UTC
Ohai!

Post title pretty much sums it up. Read up some stuff on bitcoins and altcoins, and decided to give it a try with Gridcoin.

Got BOINC installed, got the latest gridcoin-qt.msi, installed it, then tried to configure it to the best of my ability.

Problem is the miner won't start. I've added the gridcoin.conf file, server settings, used the 7870-Pitcairn profile, then created the CG Miner instance. I try (re)starting the miner from the Gridcoin module, however I only get a quick flash of a cmd window opening then closing again within a second.

Here's my gridcoin.conf:

Code:
server=1
rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcport=9332
server=1
poolmining=false
gen=0
dev0_gpu_thread_concurrency=8192
dev0_worksize=256
dev0_intensity=13
dev0_lookup_gap=2
dev0_enabled=True
dev0_name=0 - Pitcairn - Advanced Micro Devices, Inc.
dev0_gpu_thread_concurrency=8192

And here's my cgm0:

Code:
{
  "pools" : [
      {
          "url" : "http://127.0.0.1:9332/",
          "user" : "username",
          "pass" : "password"
   }
],
"api-listen" : true,
"api-port" : "4000",
"api-allow" : "W:127.0.0.1",
"intensity" : "13",
"vectors" : "1",
"worksize" : "256",
"scantime" : "7",
"kernel" : "scrypt",
"scrypt" : true,
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"gpu-engine" : "0",
"temp-cutoff" : "80",
"temp-overheat" : "70",
"temp-target" : "60",
"gpu-threads" : "1",
"temp-hysteresis" : "3",
"gpu-platform" : "0",
"device" : "0"
}

Any idea how to proceed? Cheesy

Such cheers, very holidays, wow! (during my research I stumbled over dogecoin, and thus the doge meme)

EDIT: Solved by changing the gpu-platform setting in cgm0 from 0 to 1.
