Sounds pretty stupid to me now that i have a bunch of test miners with passwords i would like to change but cant.

I know this sounds pretty simple but how do you delete workers from BTC Guild? i can only rename or hide/unhide.

scratch that i think i found my issue

Sorry i did not explain more but my symptoms are freezing the computer in full. So i need to do a hard reboot of the system.

I am also having the same problem but with stock volts and core. All the cards under full load are not going above 60c. See specs below.

I am running guiminer 20110701 win 7 64
Stock volts, 800/500 core/mem poclbm -v -w128

SAPPHIRE 100297-2L x4
MSI 890FXA-GD70
COOLMAX RM-1000B 1000W ATX (motherboard and 3 5830s)
ANTEC Neo power 430W (For 8 80mm fans 2.5 HDD and on 5830)
AMD Phenom II X6 1100T
G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1066 (PC3 8500)

when i drop to 2 cards PCIE slots 3 and 4 it works fine.

Any suggestions would be great.

thanks,

I currently have 2.5ghash in one pool but would it make more sense to split it in half and go 50% slush 50% deepbit?

You may want to try turning off the W7 Aero themes. i have a quad 5830 miner with random freezing on stock speeds with my AC blowing right on the cards (gpu1 58c gpu2 60c gpu3 60c gpu4 48c). after turning off aero it became stable under full gpu load and i could over clock them to 1000mhz. just a thought.

That sounds about right. take a look - https://en.bitcoin.it/wiki/Mining_hardware_comparison Nvidia is just worth the the power used to mine at the current difficulty,
