Now to get Sammy1 re-installed with Linux and BOINC. Just had to sort out a little mishap with the remote management cards fighting over IPs on the router, but that's fixed now. :)
I also got a little sidetracked fiddling with the alsa usb sound driver, I've been trying to get 5.1 analog out of this usb card and it took writing my own patch to the driver to get it working... gotta love Linux!

The 64 bit requirement for folding is only if you are running SMP on the CPU under Linux. If it is SMP under Windows, 32 bit is fine. GPU only needs Windows (though some have gotten it working under Linux). So with running WCG on the CPU, bits are a moot point :)

either that or f@h needs to get serious about a linux gpu client, they've been talking about it for a while now it seems.

Yes, unfortunately that is exactly the type of load you see..:shrug:

nvidia or ATI card?

nvidia should take only a couple percent at the most. ATI does take a whole core by default unfortunately, but if you tinker enough (and pull a few hairs) you can get it to drop down decently enough. Not as low as nvidia but usually pretty close.

MM: which mounting holes does this mobo have again? s604 or s771?

s604 IIRC, but the height is different so s604 heatsinks won't fit.

s423, s603, s604 and lga771 have basicly the same mouting holes :)

i decided to mod the pci-express x8 slot to fit my 9600gso. Took me a while with my knife and stove, but it wroth it. :D

Did you avoid chopping the trace like I did :rofl:

Right here. Instead of taping the card, i tape the screw with electrical tape.

I find myself wondering if a better solution would be one of those pci(e) risers that adapt 4-8-16 slots (example): http://linitx.com/viewproduct.php?prodid=11681

i have an issue where every once in a while usb1 and my 9800gtx both grab irq 16, and sometimes that results in stuttering on my usb devices.
i had to add 'noirqdebug' to my grub init line to resolve that (not really a resolution, just prevents the kernel from trying to jump in to 'fix' things by disabling the irq and making it even WORSE).

i also noticed that the EDAC module goes completely CRAZY posting errors to dmesg every 100ms when the video card is doing 'work' (also known as playing X-Wing Alliance...) or anything that requires 3d acceleration.
looks like it doesn't appreciate being on a gen1 pcie 8x bus and would rather have room to stretch its legs...
i fixed that one by just disabling the EDAC module altogether!

anyway, just wanted to share that i didn't have any of these problems with the quadro nvs 290 or the geforce 8600gt because they're not quite as hungry for bandwidth. with the geforce 9800gtx, i can really see that it's starving for a wider bus.

So far, i have not experienced any problems yet.

you have a case that allows your to mount your card horizontally? if so, go for it. if not, then you have to find one that rises up vertically.

Edit: here is one:

Oh yeah, the motherboard has pci-express x8 slot not x4.

Just got a weird error on sammy 2. It gives a "processor missing microcode" error, listing it 4 times (for all 4 cores I presume). What's up with that? The BIOS seems to be reading the chips OK, and it is booting off the windows disc fine :shrug:

check bios version and make sure your on the newest..
could be a newer cpu and older bios.

Ah OK... going to update it now. Safe to do with these chips that it is apparently a little unsure of?

Update the bios then is fine, but i did not bother to update it because it is too much work.

BIOS update fixed it :D

Did you use floppy or usb method?

ooh how it sucks to have no money.. I just stumbled across a deal that might interest sammy owners.. Kingston, 4x 2GB DDR2-400 ECC/REG DIMMs (8GB total) for USD$60 (2nd hand of course)... anyone want? :D I will post link.. later.. :p:

to compare newegg sells Kingston 2x1GB of the same spec stuff for USD$40..

Intel Board

Ok my Sammy(s) build has been forever in the waiting-life has its bumps sometimes. anyways I am setting up the board, drive and PSU on a nice clean shelf so I am going caseless. After doing some reading which metal prongs at the bottom of the board i am supposed to touch together with say, a screwdriver, to jumpstart the board? I tried last night a few times had the lights on the board once I had it plugged in; but the lights seemed to flicker on and off. Now I figure i am doing this all wrong:(. Also I am going to setup another board and all the components just to make sure it is not any of the parts.
Just to double check I have a bunch of 2gb and 1gb for all my boards-if for now I am only placing 2 of each( of course just the same number;)) which slots would they go in?
Thanks guys
