Title: "A miner that can work with memory underclocked to 300MHz and scans whole 32bit" Post by: Killdozer on August 29, 2011, 12:59:18 AM "A miner that can work with memory underclocked to 300MHz and scans whole 32bit nonce space."
This is a quote from the wiki page about the Phoenix miner. (https://en.bitcoin.it/wiki/Phoenix_miner) But there is no more explanation about this, can someone elaborate? Should I underclock my memory and use some extra options with it if I underclock? How much faster will the card peform? Seems strange that underclocking anything can improve performance... Can't find any info about this.

AFAIK the memory isn't used by the mining code and under-clocking it is simply to reduce power usage since it isn't used.
The Phoenix docs make no reference to options for under-clocked memory. I don't think it even uses the memory, or not in anyway that affects performance.

For some reason reducing memory actually does in fact also increase the hashrate by a little bit. somewhere in the clocktweak thread there is a quote with a chart. |
