Hello, I have 2 6850's mining at ~248 mh/s each.
I was curious if <2% stale/invalid shares is an acceptable number to have, if not how would I lower it.
I am using cgminer if it makes a difference.
Thanks,
Andrew

It mainly depends on your latency to the pool you are using.

You can lower it by using a pool with a lower ping/latency (IE a pool closer to your physical location)

If you're in Europe and mining on a US pool server, for example, you would have more stales than if you mined on a European pool server.

1.6% is a little bit high but still not that bad. I get about 0.7%. Anything less than 1% is acceptable for me personally.

If my post helped, I'll happily accept a few bitmills!   15rGg6A1JFZV3b7TTbtpAaiYGdUD1e1oAm

on maxbtc for current round:

62491 shares
52 stale

i use phoenix, it does getwork requests frequently

ed:

10707 shares
6 stales

since last reset and stopping a file transfer  Grin

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

With a good miner program and pool you should easily stay below 1% stale.
