[size=24][b]We need more people folding!!!![/b][/size]
I strongly urge you take another day to check things out properly before firing up the Folding. (Will also give me a chance to get some clear water between us! )Zhentar wrote:My comp is back up after no less than 4 days of downtime trying to get the new hard drive set up
Yeah - last week we were going over 3000 points/day, now we are dropping back towards 2500Wrah wrote:The Knights are now going to overtake us already in August..

Question, I am on the east coast, NY and NJ, and we have a lot of brief power outages. You know like for less than a second, just enough to have to reset the clock on the VCR and the microwave. How do you deal with that, or don't you deal with it at all?
Also are you connected to the internet the whole time you're folding? Or just at the beginning and at the end of a work unit?
Yes I will go over there and look.

You get brownouts? I'm on LI, we're pretty stable unless its thunderstorming out. I guess those are pretty frequent in the summer months ... onto your other question. I'm connected 24/7, its serious Matrix at my house, but folding only requires net access to download a WU and upload the results (15-30secs / WU).
Sounds to me like you need to connect all your electronic devices up to a UPS. Most of them can supply power for at least 30 minutes, so a couple of seconds would be a piece of cake.

Ya' gotta' have a "UPS"
Hello:
If you run a computer for even just part of the day and you do anything that you don't want to lose, I highly recommend using a uninterruptable power supply (aka UPS)! It also can protect your equipment like modems and anything else that can be blown by a power surge or brown/blackout, as well as your data, and even the inexpensive ones often have a USB connection to safely shut down your machine if you are away during a power outage. I only paid $45 for a 500va (300watt) model from APC at BJ's Wholesale Club. Win2K and WinXP have built in power management that allow you to go into hibernation at a certain battery level. So, you can work through any momentary blips or blackouts up to about 10-15 minutes long, depending on the draw of your system (LCD monitors help a lot here).

Quote from the folding website instructions:
http://folding.stanford.edu/download.html I should pic the first one, right? It says all versions, but the 2000 symbol is not there.
OK, but The only Window's 2000 option is the screensaver. See?Note: Windows 2000/NT/XP users should use a separate screensaver-only version of Folding@home (see below) if they require screensaver functionality. If you do not require the screensaver functionality, just install the client and start folding!

you can still see other pages, its like a forum at the bottom right
Turns out my laptops been trying to send a WU since yesterday morning! I lost the WU, but at least it works now. Man, I'm losing places fast....
And dukla- the difficulty was figuring out how to clone things I wanted to and having difficulty with the packaged maxtor utility.
I've got a perfectly working clone of my old windows now

OK so I downloaded the CLI version and it went out and got the exe and apparently it went out and got a work unit as well. I didn't change any settings. So now I just d-click the exe and go?
Besides that I just finished some major hardware changes, which includes a new processor, SLK-800 with a slow fan, and no intake fan. I've run Prime95 for about 3 hours, cpu temps stayed glued at 47C. I want to run it longer first before I try a work unit.
Can I stop in the middle of a work unit?
Getting more memory this w/e as well, so Monday's a good time to start folding.

I got a PIII and I'm stuck on frame 14.....wha?.... wait a minute......for some reason 6 frames just got marked completed all at once. OK so that's 20 frames in 2 hours 30 minutes. No I'm not in your league. Oh well.
My temps just sit there. 41C cpu and 30C board, 36C hard drive, after 2.5 hours of this. Things could be worse.

oops, my bad, I calculated 2.5 hours into 90 minutes (1.5 hours) and I thought I went to college ...
I recently dropped my ram to 2, kicked about 10-20 seconds per frame ... extrapolated, 10 sec * 100 frames (gromacs) = 1000 / 60 = 16.7 minutes speed up. Or 20 secs -> ~30 minutes speed up. I hope my math is right for that one, otherwise its time to study for the GREs ...

RAM latency
Hello:
As I understand it, since today's CPU's run at such high multiples of the FSB, that RAM latency is very important. Running CAS2 instead of CAS2.5 can be like a couple of hundred mHz. And DDR RAM supports only CAS2.5 and CAS2 -- CAS3 and CAS1.5 are not "real" latencies. If you're interested, there is a new RAM review over at Lost Circuits: http://www.lostcircuits.com/memory/ddr400/ that gets into latencies, and also into SPD. The bottom line is, you need to set the latency manually in order to know that you are running at CAS2, since the SPD is often wrong or it is interpreted incorrectly by the motherboard.
My APacer PC2100 CAS2 RAM is still running at CAS2 "Turbo" at 308mHz (DDR) which is a 15% overclock. Not bad for $29 sticks of 256MB RAM! It does not make it much higher at minimum latency, and as the Lost Circuits article mentions, it is better to run CAS2 at a lower frequency, than it is to run CAS2.5 at a higher frequency. Unless you just want bragging rights for running a higher number...

Well, I was just curious as to how much particulary the fahcore benefits from faster ram. It could be that it's leaning mostly on the cpu cache.
Right now all my pc's run on standard cas3 sdr. If fah likes faster ram a lot, I'll be the at the shop the next day buying a nforce2 mobo with dual DDR channels.
And the thought of building a farm (one step at a time) is still running around in my mind. (as I'm typing this I'm taking my first steps into linux which I'll need for diskless boot). The ECS mAtx board I have in mind for it accepts both SDR and DDR. I got some SDR lying around, can buy cheap slow DDR or more expensive fast DDR. I'm not sure what's the best buy. 30 mins speedup is nice though.

I'm not sure whether it is cache or latency or bandwidth...
Hello:
If F@H likes cache, then a Barton XP 2500+ should beat a Throughbred XP 2600+. Does anybody have these 2 and can compare them? If it's latency dependent, then CAS2 beats CAS2.5 by a big margin -- I might be able to test this. But not for too long...
I tend to think that it is not bandwidth dependent, but this would be tougher to test, since PC2700 is also lower latency than PC2100 -- because it runs at a faster clockspeed. Maybe the only way to try out for bandwidth is to run a single channel vs dual channels on an nForce or nForce2 motherboard. Another way would be to use an AGP video card on an nForce board with integrated video. I would do this, except there is a bug when I use an ATi Radeon on my nForce mobo: the FSB clock drops to 100mHz no matter what I set it at!
I will say that on my two nearly identical machines, the one with the least stuff running in the system tray, runs F@H about 2-4% faster! No Zone Alarm Pro, no Electron Microscope, no scanner software, no MailWasher...both do run antivirus, keyboard drivers, and I'm sure several other things. I'm running Win2K, BTW.
