Happens sometimes, check the log file for any reasons.
Try quitting and restarting.. check your firewall is not blocking..
Did it download new work?

I turned it off and turned it on again. Log file ends with multiple attemts to contact work server. I've made no changes to firewall settings and the exemptions permitting the core process still appear to apply. And no, I haven't downloaded a new work unit as upload and download connection via HTTP return 'couldn't connect to the work server' in the log file. I'll give it to 8pm tonight Eastern Standard Time tonight and then think about dumping the work data. Can you manually up- and download wudata files?

Bookmarky. Is the F@H related to FoldIt? My daughter, Phaedra (high school) has been working through FoldIt and is frustrated that she doesn't have university level chemistry skills yet. (I'm estimating a couple of more months for that, you should see her school assignment on DNA replication and gene regulation!)

Looks like sig images are down today. Or is that just for me?

Seems to be me too...

Just pulled the trigger on a I7 2600 (non-K) running @ 3.4 ghz and motherboard. I'll be interested to see how much I can generate from a ppd perspective. Should be installed by end of next week.

A very powerful cpu, I think you can still overclock these ones even without the multiplier being unlocked depending on your board.
Enable HT and let it fly

If I overclock my netbook will it increase my post count too?

Your post count? Ha just posting that in this thread will increase your post count.
We are talking PPD (points per day) and yes if you could ( ) force the multiplier on your net book you could increase yours.. Or melt it.. but really you are unlikely to melt anything with an overclock, usual result is BSOD and when I overclock I go for BSOD and wind back from their until I get it to post.
Extremely difficult and anyway not recommended to OC netbooks, but tell us how it goes

The CPU is going to be in a HTPC, so I bought a non-overclocking motherboard - worried about too much heat generation in the cabinet it is stored in. I may get a couple of USB cabinet fans of Amazon also.

I know the processor is way overdone for HTPC duties, but I've future proofed myself for a while and I get the folding benefit.

And hey, they are not so expensive and seem to be an excellent reliable model that just happens to kick arse folding SMPs.. and whatever other multithreading things that need to be done.

So - just received and built the HTPC with the I7-2600 on a mini-ITX. With the 8 cores, it seems I may be getting some pretty large units, since I am getting some lag on windows media center (which is how we primarily watch TV in the house). I've set the SMP client to "small" units, but if none are available - I guess I can end up with some pretty large ones. I'm trying to think about ways to reduce the folding overhead - either turn off hyperthreading or possibly restrict the SMP to a fewer number of cores (6 or something similar). Right now I am running project 7142. Any thoughts would be appreciated.

Just because everyone is on the edge of their seat, I turned off hyperthreading and deleted the current work unit and now WMC is much more responsive. I think I will play a bit with adding hyperthreading back in and limiting the SMP to a subset of the total of 8 cores (and see which configuration gets me faster throughput). Is there some line that FAH draws where if you have 7 cores you get normal units and 8 will get you huge ones?

If I am asking questions that are easily answered on some other FAQ, please let me know.

No you just get normal SMPs unless you request otherwise, it used to be that you could is super overclocked have attempted Big Advanced ones but that option nolonger open for quadcores on HT.
The bigger normal SMPs will have longer deadlines, you should try on 6 or just stick with 4, people have reported problems with trying with 7. I understand that running 8 was causing some problems as you were really maxing out your 4 cores there.

I have decided that there is another issue here, the amount of lag even running on only a couple of cores is way to much - especially considering I have two other lower spec systems that run the smp client with out a hint of delay.

So, either my power supply is undersized at 400W or there is an issue with the heatsink on the CPU. During the install a couple of the pins that attach the sink to the chip were broken. The sink sits there pretty well, but I'll pick up a new sink/paste/power supply this evening and see if one of these two issues resolves the problem. Troubleshooting is fun!

So got realtemp and found out that I was hitting the TJMAX temp on the proc due to an improperly seated cpu cooler. Purchased a thermaltake (a little loud), but now my temps are good, I'm ticking off a percent of the WU every 45 seconds, and there is no lag. Thanks for the sounding board!

Good you found the problem, the PSU is a tad small depending on the rating and what else you are running.
The old thermal issues with the cpu problem eh, used to be it would bsod if got too hot but these modern board just slow stuff down. I still think running all 4 cores on HT on an SMP is really maxing the system if you are using for other multithreaded stuff nd that 6 could actually be quicker. But no doubt you'll let us know.

I certainly will! I did a check on the PSU and I should be good. The only other power draw is the worlds smallest graphics card and a 3 TB hd. I don't use the dvd drive (physical media is dead).

One question. Should my user name and passkey return bonus on this machine immediately, or do I need to complete 10 units on this machine also?

I will . 6 cores is almost a linear 25% increase in time between percentage ticks, while 7 cores results in only a 7-8 second slow down between percentages. So I am running the 7 cores now.

You need quantumthreading there DK - I know this bloke who can get some good Russian stuff for you, only a couple of hundred bucks, PM me your bank details..... Shh. Mum's the word right....
