Overclocking with poclbm/live-miner

Running this on a headless machine: http://live-miner.github.io/

The thing is ticking away fine at ~380mhash/s and feeding to my pool:

PhenomII 955 on an ASUS M478T-E motherboard with 4GB ram and a 6870


I was able to underclock the phenomII 955 to 1ghz in the bios... but I can't for the life of me get the GPU to overclock! In the live-miner.conf I set these arguments:

Code:

# poclbm arguments; overriden by 'live-miner.args' boot parameter
LIVE_MINER_ARGS='-v -f 0 --gpu-engine 1000 --gpu-memclock 300'

The memory downclocks to 300mhz, but then the core drops to 183mhz and the GPU voltage stays at 0.8V!

I tried removing the --gpu-engine 1000 argument thinking I'll run the stock clock and lower the memory clock to save on some heat, but I get the same 183mhz/300mhz 0.8V result... If I remove both args then it goes back to the stock clocks. What gives?!

Neat setup:). However, have you tried using cgminer, from what I've heard, cgminer is by far the best client to use when trying to GPU mine or overclock.

Is there some simple way to compile CG miner into this OS? (see first link in OP)

I'm horrible with linux...what I love about this is the thing runs off that USB drive, boots on LAN, and automatically goes away into mining. Don't need a HDD, nor do I need to run any kind of fancy pants OS. Plus, if the power goes out, it'll just fire right back up and get back to work without any intervention!

Or is there another headless USB-boot OS I can set up easily which will auto-mine on LAN boot?

No help?

bumping again, i know this card can do 420+mhash...

also turns out what I thought was a 6870 is actually a restickered 5870
