Building a Sossaman rig?

He came down to $180. Seems like a good deal.

That's what he did for me too. I bought three - each a week apart. All running good and generating 6-8K WCG ppd. Great surfer too. He started with 36 a listing back - last I looked he was at 32 so he sold one other besides the ones I bought. He's a quick UPS shipper and very well packed in custom fitting foam. Only glitch I had was one of the ethernet ports on one machine wouldn't always hook up on boot - always would if I would then unplug it and stick it back in so I went to the second port and no problems, probably a flakey connector on the MB. Good luck, there's no CD drive, I used a netbootin Ubuntu stick, it sees it as a HD in BIOS and takes off. I turn off the network bootup options and pull the ROM expansion board out, two of the three had them in it, one did not. Good luck

Thanks w0en for the info. I'll hit you up on that ROM expansion board later for a pic...

It will boot with it in there after you reorder boot devices in the bios - I just took it out later as extra figuring it must use some power. I'm not an IT pro or familiar with servers and how they act, but it must have something to do with addressing, it has a number taped on the back. It's on a vertical riser card, hardest thing is how to get the plastic locking device in back loose so you can yank the riser card out. I don't think the machine will boot until you take out the network boot references, either reorder to the bottom in BIOS bootlist or disable them, sounds harder than it it. Others have referenced the Soussaboards long blank screen pause before bootup starts too, this is no different so wait a minute before you get nervous that it's TU. I think later there is a tweak that you can turn down a delay timer in the bios that will make it boot a little sooner. Escape gets you into BIOS there is some other GRUBlike software that comes up first and then complains and quits. Going into it offers no changable options, you need to get into the BIOS and make the USB stick/HDD the first boot device (there isn't a USB boot option)or install a CD and use it (which I haven't tried, YMMV).

I Googled the card after I got home tonight - it is a Cavium Networks Nitrox XL NHB Security Acceleration Module. I don't think we need it for crunching WCG....

Oh that helps accelerate the encryption and decryption of VPN tunnels.

general question that i was wondering is if im running QX6700@3.52 i get about 1800ppd. why does sossi get 7-8k @2ghz with 2 dual cores???

Comparing equal point types?

There are WCG points and BOINC points. 1 BOINC point is roughly equal to 7 WCG points.

[w0en]

Part of the WCG/BOINC credit confusion stems from the fact that we tend to refer to them all as "points", probably because everyone is so conditioned to sports teams comparisons. I believe credit in BOINC is more correctly measured in "Cobblestones"
Stolen from WIKIpedia:

Cobblestones
The basis for the BOINC credit system is the cobblestone named after Jeff Cobb of SETI@home. The basis of the system is the concept that 100 cobblestones would be claimed for one day of work on a computer with the following specifications:

1,000 double-precision MIPS based on the Whetstone benchmark.
1,000 VAX MIPS based on the Dhrystone benchmark.
The actual computational difficulty needed to run a given work unit is the basis for the number of credits that it should be granted. The BOINC system allows for work of any length to be processed and have a user claim identical amounts of credit.

To achieve this BOINC uses benchmarks to measure the speed of a system and in combination with the amount of time it required for a work unit to process can “guess” at the amount of credit it should receive. Since systems have many variables including the amount of RAM, the processor speed, and specific architectures of different motherboards and CPUs, there can be wide discrepancies in the number of credits that different computers believe that each work unit requires to process.

I'll make it easy..
Here on Xs we tend to talk WCG points soa Sammy gets 7500-8500 points a day at 2000mhz and app 6700PPD with the 1667's..
Easy..

[NKrader]

oh makes sense

and one more question heh

can sammy run off 1 stick of ram? what would be least amount of ram that you should put in it for dedicated cruncher.

[Sparky]

Not sure on the 1 stick part. But 1GB works.

[NKrader]

1GB (2X512MB) PC2-3200R DDR2 400MHz ECC Registered Memory Modules

correct Ram?

[Sparky]

Yep sounds like it to me

[NKrader]

Yep sounds like it to me

sweet now all i need is heatsinks and cpus

[Sparky]

Heatsinks:

[NKrader]

score just got 2 cpus for 68$ total.. what eva only 34$ per CPU.. after stupid shipping.


EDIT:
and heatsinks, now to sit and wait for it all to come in the post...............

also have to find a psu..

[stangracin3]

what is the exact model of the intel board?
in all of the pictures i cant see a name like on regular boards.

[hedge]

Intel SE7520BB2

trying to find a better price?

and its a busness board doesnt have some trendy name made by their marketing dept.. as companies dont care lol

[retro77]

As posted earlier by someone else:
Intel SE7520BB2 $9.99

thanks i had been googling different combinations of server 479 and intel dual socket for an hour lol

[retro77]

No prob. I started bookmarking these tidbits.

[stangracin3]

also how do you guys find such good prices on the cpus?
