Folding on a X2 4400+ is it safe? Only goes 50%...

Im also worried about the heat of my CPU, it goes rather high. Why does it only go 50%

Im worried that this constant overwokring of this one cpu will mess up the other.

the X2 4400+ is a dual core cpu so don't you need two instances of folding at home to make it use 100%?

check here, you need to get the dual oneclick. If you installed the official stanford version you need to install a second client (rename it FAH2) and each instance will use each core.

file has virus just to let you guys now :mad:

[Rpkole]

are you using nortan then yes it might say the .bat is a virus but it is not

[godofgorks]

It thinks it's a virus because it connects to Stanford to download the FAH program. That way it stays within the policy Stanford has setup to only download from them.

You don't have to worry... it's not actually a virus :)

[the garynator]

nope, not a virus... norton = annoying

FYI... eTrust AV does the same thing. And it's hard as crap to disable it.

[Amoroso]

is it okay just to run 1 FAH? Id like to keep the other 50% open to do my other stuff like gaming and etc. Im asking if its just safe to have one core on full load constantly and the other core on idle most of the time?

Howdy Amoroso,

I've a AMD64x2 3800, and didn't really want f@home to run either core at 100%, so I changed it to use only 95%. You can choose it very easily, here's how:

Get f@home client up and running. Press Alt + Ctrl + Delete, all at the same time, to bring up the Windows Task Manager (if you need to choose that from a menued screen, then just double click on "Task Manager", from that window.

Now click on the tab at the top that says "Processes", and look down the list. You'll find the name of the f@h program executable, in my case, it's name is "Fahcore_78.exe", but I'm using the graphics console in error, so get Fah file that is showing a lot of activity for itself in the list, on your system. Put the mouse pointer right on it, and right-click. Now run the cursor bar down to "Set Priority", and select that heading on the left side of the selection window. Now you can set the priority for whatever you wish. I'm using about 95% right now, but in the Summer, in Phoenix, I'd sure want to lower than during the hot Phoenix Summer/Late Spring/Early Fall, OK, almost any day but the dead of Winter. ;)

Also, I'd check and be sure you have a program loaded (or BIOS), that will shut down the computer if the CPU get's too hot. About 10 degrees before your system or CPU get's to that upper heat limit, it would be nice if it would beep loud, etc., to warn you of the problem.

I don't have any info on whether it does or could damage the CPU to run unbalanced (one at full bore, the other basically doing nothing), but you might ask in the AMD forum, and see what they say. My instinct is to lower that priority to 90 - 95%, and spread it out across both processors. If generated heat is the problem, then lowering each core's priority down more, should do the trick.

Note: the priority I'm talking about is the MAX priority for the process, and has nothing to do with the priority the f@home program keeps for itself.

There aren't any moving parts in a cpu to wear out. I've got 60+ cpu's running @ 100% in all sorts of rigs and haven't lost a cpu yet. THe FAH client backs off rather quicky so setting priority is unnecessary for anything but laptops where heat might actually be an issue. Any OEM heatsink should handle the heat of 100% cpu utilization 100% of the time.
