I have been digging through some old archives that I've only recently been able to access again.  First thing I went for is my old BTC & LTC wallets, as I know that they had some currency left in them when I was forced to abandon them.  Unfortunately, I don't have a clue what version of the software they were for; I only know that it's not anything within the last few years.  I believe that they were last used about 4 years ago, maybe 5.

Does anybody know of a method to determine what version of the bitcoin wallet this wallet.dat file is for?  I've tried perusing the file for strings, and nothing intelligible regarding a version, or even anything that looks like a version #, is appearing.  Any help would be greatly appreciated on this matter.  I'd be happy to toss some BTC to whoever can help me figure this out, though I can't promise it'll be a huge amount.

TIA!

I recently realized that, with the difficulty that bitcoin mining has reached, using my electricity-guzzling GPU to assist on mining when I have a small ASIC rig for bitcoins was foolish.  Previously I'd only been using CPUs for mining litecoins, but I disabled the GPU on the BTC mining process and started a new cgminer thread (on Debian Linux, cgminer-3.5.0) just for scrypt/LTC mining with the GPU, and the reported kilohash rate is blowing away anything I've ever made with my CPUs' processes.  This is with a standard long-polling of my pool at ltc.kattare.org, fwiw.  Now here are where things get odd...  I'm having enough rejects/stales so that it's bringing my hash rate reported @ kattare wayyyy down, like from the 150+ KHash/sec reported by the miner to somewhere between 20 & 30 KHash/sec reported at the pool, with a huge amount of round stales.  My CPUs don't have anything even close to the percentage of stales/rejects that my GPU is getting.

• I tried going for a stratum+tcp configuration, and when I do that, I can't break 30KHash/sec, with kattare or another pool that I tested on.
• I'm working with a Radeon 5xxx card, and the only other thing I can think of is maybe it has something to do with the difficulty of the shares I'm being given.  Other than that I don't have a clue.

Does anybody have any pointers to resources (I've been googling but haven't found anything yet that's helpful) that can help me get my KHash rate up to where it should be on the pool?  Or any direct experience?  Or maybe even input on if kattare is a poor choice in a pool or anything?  Anything you can offer is very much appreciate.

Thank you for your time!

Just got my 'entries' in as best I could.

• I did #1 with the comment.  My bitcoin payout address is 19rebibVoGekFTwJAwsPZFDodVX2sY1Vyw, and I've visited your site.
• Also shared most recent post on facebook.
• Finally I wrote about you right after sharing that post on my own facebook page (username khelair, real: Damon Getsman)

So I guess that'd make 1 + 2 + 5 + 15 for 23 entries to win that free BTC.    Thanks for the service, you guys!
