Re: [XPM] Primecoin Built-in Miner Sieve Performance Issue

Here's another binary I've made which targets simply x86-64 processors. This SHOULD work over a wider range of processors than my earlier releases. It may not work on 32-bit OSes (not sure).

Try using -debug and -printtarget and post the ERROR messages about block #3 being rejected again

This gave me a little hint. FYI sunny, the code this was built from is here, it is slightly modified from your latest commit to include some additional suggested optimizations from Mike270. https://github.com/Zalfrin/primecoin

There may be a bug in the way the "phash" variable is replacing "pblock->GetHeaderHash();". Maybe phash needs to be updated within the loop starting on line 4640 of main.cpp
