Merlyn and fullerine, I've seen you haven't turned in any results yet.

Is it a connection problem?

Go to the advanced statistics page provided by Team MacNN.

Hmm, something doesn't work so well there. Most of the members have "Insufficient Data", at least atm.

It usually works well. Try again later.

16th Place in the All Time stats!  Man, we are good!

It's especially amazing considering we have only been doing it a few weeks, where other teams have been registered for over two years.

Just dumped 309 candidates from my 3 Borg'ed computers to add to my normal ~150 per day. Kept us within 400 of the Yogurt team which has really been crunching a lot recently.

Anyone know how to re-use a Node Id. My notebook hard drive decided to go with the click of death (It's a travelstar). And nope, I didn't back up D2OL's directory :(

Otherwise I'll end up with more nodes than real active nodes....

Not possible if you didn't do this:

Nice code, looks much more efficient than the stuff I copied and pasted :)

Losing time does suck. Watch out people, Im catchin up ;)

Just wanted to bump this thread and encourage everyone to join the team. The bottom 13 are inactive and have been for some time. We need to maintain our momentum! Currently we are 16th overall after just 37 days of crunching! I just brought on another p4 2.66 to make up for the blistering p3 500's running day and night. Hopefully our inactive members have been working offline all this time.... ;)

Anyway, JOIN!

Looks like we will be able to break into the top 10 fairly quickly....

The tough part will be then taking on the teams that produce a lot, and have been doing so for a long time.

Just keep on crunching!!!

Athlon XP 2200, 256MB DDR266 RAM

I would be running this XP 2600 I have sitting in my desk, but my current motherboard doesn't support it. I will be soon upgrading motherboard + getting 1GB RAM; I'm looking at the NForce2 400 series boards right now as I am seriously unimpressed with VIA's track record re: chipsets. Any recommendations?

Been lurking and running the D2OL client for Team StorageReview for a while now, just got to reading this whole thread and thought I'd post my specs for comparison and whatnot.

Well it depends on what you need in a motherboard, but satart a new thread with what you want ;)

qwerty3678, what hw are you using? My Node is an Athlon 2400+ (15x133) on Nforce2 400 with 512MB DDR266.

I've been quietly crunching on a P4-2.8C @ 3.3GHz, basically 24x7. Your Athlon seems seems much more efficient at doing this though... your average candidate time is even lower than mine!

I've got about 1000 units just waiting to be uploaded....should I wait and build up more or upload them now? :unsure: Heh heh!!
