Hello

I am hoping you guys can help me with my cgminer crashing. First off, here are my two PC specs:


Main PC (Gaming & Mining)

Intel i7 2600K @ 4.7GHz
Asus P8P67 Deluxe
8GB DDR3 1600Mhz RAM (2x 4GB)
2x Saphire 6950's flashed with 6970 BIOS + overclocked
1x XFX 5870
AX1200i PSU
Various Hard Drives (2x SSD's, 3x HDD's)
Windows 7 Pro x64 SP1, AMD 13.6 Beta Drivers, SDK included with 13.6
CPU and 3x GPU are all under water


2nd PC (Mining 100%):

Intel G550
Asus P8P67 Pro
4GB DDR3 1333 RAM (1x 4GB)
1x Powercolour 5870
1x Sapphire 5870
Corsair HX620 PSU
1x 120GB HDD
Windows 7 Pro x64 SP1, AMD 13.6 Beta Drivers, SDK included with 13.6
2x GPU Underwater

Now my problem. Whatever I try on my main PC to mine, cgminer will always crash. My 2nd machine is happily mining LTC using CG miner. When I was first setting that up, it would crash sometimes depending on settings. I believe this to be due to the TC setting but after some switching around, the 2x 5870's are mining fine.

On my main PC, everything I have tried doesn't work including:

• Lots of different settings in the cg miner config as well as trying to use GUI Miner. In GUI Miner it crashes just after it says "starting" on all 3 cards. I have tried varying versions of cgminer with no effect. I have tried mining BTC and LTC with no change.
• Using a java program to generate a batch file. No effect. I have also tried using batch files and the general config for CG Miner.
• Loading cgminer and entering the information manually in the command prompt. Its lets me enter all the information and will crash after entering the worker password.
• Different AMD driver versions, however with 13.1 and 13.4 (the only 2 I have tried really), my PC will blue screen either during installation of the driver or upon the restart. I have used the AMD cleanup tool as well as driver cleaner. No change. I believe the blue screen is caused by a corrupt dll for CCC. I was in the process of manually extracting and replacing that file, however I couldn't delete the original from within my own Windows installation. I will try to resolve that as soon as I can (see next point)
• I performed a clean install of Windows on a separate partition on my main SSD. I have a Windows install identical to my Mining RIG with 13.6 (as in not a copy, just installed the same software). No change. This was a very bare windows install with no overclocking on the GFX Cards. I don't think it is driver related as it works fine on my 2nd machine with 13.6 I believe.

Few things to note:

• MY PC is 100% stable with overclocked settings, will happily run prime 95 for 12hrs+ as well as graphics benchmarks with no issues.
• I originally had Kaspersky IS on this PC, it is currently disabled but the 2nd machine + clean install does not have any A/V installed.
• Nothing is overheating. I am running both machines on water. On my main PC with all 3 cards @ 100%, temps are normally 55-60, 53-58 and 45-50 across the cards. 2nd PC usually has temps between 45-50.
• Last August I managed to mine BTC with cgminer without any problems when I had 2x 6970's
• I am currently mining BTC on this PC with the bitminter java app. No problems with this, can happily run all 3 cards at the same time and I leave the PC mining this way during the day and overnight.
• I don't really want to use any earlier than 13.x drivers, due to the fact I game on this PC a lot. I am not worried about any drop in mining speed because of that.
• I have worked with computers for years. I work with PC's all day in my day job (work in a local PC Shop, fixing computers etc etc) so I am very familiar with troubleshooting / fault finding.

Does anyone have any suggestions on how to resolve my problem. Been spending ages trying to get it sorted.

I have no doubt left information out. It's quite hard to remember everything for one post

Thanks in advance for any help.

Guiminer is just a graphical interface that uses cgminer and other mining tools.

I already have one PC setup. I don't think its as simple as "watch youtube" seeing as just running cgminer --scrpyt it crashes.

Anyone?

Does your motherboard have an extra 4 Pin Molex or 6 Pin PCI E connector? Generally if you are running alot of cards at once, you want one with one of the connectors to supply more power, so you dont burn out your 24pin.

A small update.


I got it working on my 2nd mining machine ok (2x 5870's). I found with tc settings alot of the time it would just crash when trying to open. I guess thats just because of it not being shaders * a number? I got it running atleast and has been mining ltc for 2 days.

On my main machine (2x 6970's, 1x 5870) it just crashes when starting. If i run cgminer seperate (i decided to do that on my 2nd machine) the program crashes. If I run guiminer, cgminer crashes as soon as I start. I have tried fiddling with the settings and config files but nothing seems to work.

I did have a go at changing drivers (on 13.6, same as 2nd machine) but for some reason this pc never liked older 13.x versions. I use it for gaming as well so dont want to go with really old drivers but Im hoping that isnt whats wrong.

Any suggestions?

Hello

I am wanting to move to mining LTC with a gui based miner. I believe the above miner should work. I have tried to set it up however it is just stuck on "connecting".


I was planning to use wemineltc.om

I used the following settings taken from their website http://wemineltc.com/gettingstarted

host: stratum2.wemineltc.com
username: myusername.workername
password: my worker password

Left everything else as it started. Use Stratum is set to yes.

Can you help?

Thanks
