I checked with the people on ebay I usually do business with but they didn't have any of those. One place had several but they were the 1800+ 's and up. Sorry, I'll keep an eye out while browsing though.

Thanks Jim. I don't think that very many were made, so they aren't that common.

Just got 608.89 credits from QMC on my PII running Linux. This is my record for any project. Downloaded 4.16 beta app from Einstein and running SETI.

QMC now has workunits that

QMC now has workunits that take far longer than even the longest monster units of S5R2. I saw one report of a 2090 credits super-monster. Apparently two teams ("SETI@USA" and "Planet3DNow") have chosen QMC as a battle ground for a race-like competition and kind of drained the project so that they had to generate new workunits that happen to be extra long.

I suppose the organisers of QMC would have to be ready for increasing workload. Otherwise the reason of such kind projects is drained to zero.
The main purpose of software-distributed projects AFAIK is to solve the complex task with huge computation time in shorter terms and with maximum productivity.
Otherwise this task may be solved in many years of idle time of any university's machine and this solvation would be very cheap.
All the participans are getting this with the main aim - to solve the task as fast as possible. And the productivity of the server side is not my headache, but of the project organisers.
And we all here (participans) do our best (buy cheap, but enough productive computers) to solve this task ourselves. So, the problem is only on the server side, I guess...

Hey, my extra 1GB memory

Hey, my extra 1GB memory finally arrived and now my two dual PIII-S boxes have 1 GB each. I took the opportunity to measure the power consumption, and it's around 135 W (for one server Dual PIII-S 1.4 GHz, 1GB RAM, 1x 36 GB HD, onboard graphics) .

They yield about 420 credits / day, or 17.5 credits /h , so they need about 7.34 watthour per credit. I think that's not tooo bad in the server/desktop league.

My Mac Mini needs about 1.2 Watthour/credit, but it's build from notebook components so it's playing in a different league.

Wanted to see wether my old

Wanted to see wether my old iBook still works - the first one ever built in 1999, G3 300 mhz.
Just for fun I let it crunch an Workunit, after 332,998.84 seconds it finally finished.
It's fun too see such an old machine, that shared so many memories with me, solving
tasks successfully, but since it hardly is power efficient (45W Power Supply) I put it
gently back in it's place until the next time I want to see wether it's still working.

RE: I've been paying about

I've been paying about $20 a GB for PC1600r in 512MB modules and $25 for a GB of PC133r in 512's. Picked up 2GB, 4 512's, of PC133r for $22 tonight. It should be here by the first part of next week.

It just seems strange that the 133r would still be higher than either the 1600r or 2100r. It's still cheap compared to what memory used to be. Remember those 1MB modules when they sold for $40-45+ each?

Okay, I'm going to show my age here, but that's okay.

My first computer was an 8 megahertz 8088 machine. When I bought an expansion card so that I could make use of expanded memory, I paid about $300 for one megabyte worth of DRAM chips.

Times have certainly changed.

@Bikeman - out of interest, what sort of price do you expect to have to pay for your RAM in Germany? I was interested to see Jim's $25/GB figure for USA. In Australia, on ebay, people seem to be asking around $60-$80/GB but I suspect that actual sales might be lower than that - maybe around $40-$50/GB. It would also depend on the size of each stick with a premium for larger capacity sticks.

Hi!

I got mine the traditional way at ebay, which is the least time consuming for me. So I will get a single 1GB module for 21 EUR by tomorrow. I think this was a bit on the cheap side, usually they sell for around 35 EUR over here, but the seller tried to dump 16 1GB modules in a single multi-auction and there just wasn't enough demand at that particular time to drive the price up. :-)

I've had good luck buying computers from e-Bay, but have had a few bad experiences buying memory. One time, I needed registered ECC memory for one of my servers. I bought from a guy who advertised that that's what he had. When I received it, it was neither registered nor ECC, and he just threw it into a regular bubble-pack envelope for shipping. No anti-static bag, just that regular bubble-pack. So, in addition to it not being what I wanted, it was also fried.

From now on, I'll stick to buying new memory from regular retail outlets.

Memory was delivered today

Memory was delivered today for the 440, works great, no fault lights or errors, to bad the OS hangs. :( Tried with HT on and with it off, same thing both ways. Wondering if it makes a difference that only the one SMP module was enabled when the OS was originally installed? Think I'll run it dry and try a re-install on the OS in a couple of days. It's either that or find one of the 12.7mm slim DVD drives and load Server 2008.

I was looking forward to running all 8 cpu's with HT on, just to see how it would do! :(
