It's a bit long to cut and past here, but re-reading it I am reminded that it has been discussed before on this forum - HERE and on SAH - HERE

Alex:
It does in fact seem to have been shared memory. I've yet to see a single error since changing the settings this morning.

Thanks for the quick reply with a pointer to the implementation instructions. Keep up the good work.

Thanks, K - I remember the discussion now. I haven't had that problem occur (yet), but I think I'll go ahead and change the shared memory settings anyway, as I often have a lot of apps running on here at the same time.

Here's a weird one for you. I ended up invalid on my PM G4 using your latest client, along with a couple of PCs, but a couple more PCs and a MBP running the default client, ended up valid.

Workunit

I can't find a copy of SETIgrabber, so I haven't been able to get a copy of the WU.

Happened to me as well.

Hi again, i just made CPU upgrade to mac pro. I change dual-core 2,66ghz to quad-core 2,33ghz (Xeon E5345)
Lets see what 8 core mac can do......

Sweet! Can you please provide details of the upgrade? Did you follow the process at AnandTech? Did everything just work after the chip swap? Or did you have to make any other modifications? How are the temps? Are they any higher after the upgrade?

[alexkan]

E.T, have you increased the amount of shared memory available on the machine? Considering how many problems the Quads (both PPC and Intel) have had, I can imagine that this beast needs the shared memory even more. Those initial errors seem a little worrisome.

Looking forward to seeing how it performs.

Also, you need DIMMs in sets of 4 to get the full memory bandwidth. Without at least 1 set of 4, performance will poor. Do you have at least 1 set of 4?

Yes i have 8 x 1gb FB dimms, something is broke again in boinc client.
I think no one has change source code -> total memory is hw.memsize: not hw.physmem

Which version are you using? I have been using 5.8.2 without any problems.

Also, have you tried this?

Configuring Shared Memory on Mac OS X

I have done this with all my macs.

I mean boinc just report wrong amount of memory, 2048mb is max.

I don't know how the AnandTech make those but...
1) Most difficult part is dissasemble the fan from tunnel.
Fan has clips on each side near of corners against tunnel. I use PCI back plane shield as a tool to dissassemble fan. Fan comes in to tunnel.
Of course screws against bottom of tunnel are glued tight, as an result i need to change screws (i need to use pliers to open ) I believe that this is made on purpose. After cooling tunnel is dissassembled rest is quite easy
2) Pull heatsink cover out
3) just screw out heatsinks and disconnect sensors from motherboard
4) open ZF processor socets and replace new processors
5) put some heat conducting agent top of processor / clean heatsink plate
6) There is sensors in heatsinks remember to connect them.
7) put heatsinks on place, tighten them carefully.
8) put all together. Check carefully that there isn't any extra objects inside and fire it up.
It takes about 15minutes.
That's it, nothing else.....

I didn't realize any difference in temperature, but i tell more when i have better knowledge

I think i screw up to join project, it start calculating with std cliend supplied by seti. Then i change client and as a result i need to reset whole project :-) Anyway i test first under 10.5 dev seed, doesn't work at all...
anyway i change my shmem:
kern.sysv.shmmax: 67108864
kern.sysv.shmmin: 1
kern.sysv.shmmni: 128
kern.sysv.shmseg: 32
kern.sysv.shmall: 4096

I tried that way first -> too much violence That's why i decided to remove fan and open screws from tunnel.
Then there is enough space. http://esa.tienhaara.net/seti/pics/05092006097.jpg

Just hit 2392, #74 on teh top computers list!

With the problems you will probably drop off a bit though.
