Lets see what this can do.. any advices on the settings for the BitMinter?
Lets see what this can do.. any advices on the settings for the BitMinter?Bitminter doesn't really have a lot of customization. It is a very good miner made by the pool author for "casual" miners. If you want max control you should look at cgminer. Try adjusting core clock and memclock. I find 800/300 a good place to start. I run most of my cards at 820/190 some slightly higher, some slightly lower. Each card is unique in what it can handle.
Once you get a miner stable for say a couple hours they may still go dead after days. Bring the clock down slightly. You will find the final clock which is stable 24/7 for weeks (sometimes months). I have one rig going on 48 days of uptime (I haven't even upgraded cgminer because I want to see how long it can go). Barring no power outages I think it could run until summer w/ no downtime.
I know a fair bit about overclocking, but im completly new to mining
Ive been trying to get guiminer and phoenix working properly, but guiminer is damn slow and phoenix gives me tons of disconnects.
