[QUOTE=petrw1;384700]I hope not. It is a brand new PC at a friends work place.

I am prone to believe it is just a very poor setup.
That is, akin to a Lamborghini CPU Chip with Ford Fiesta RAM.[/QUOTE]

A Ford Fiesta ST is a nice car :)

[QUOTE]Would you be kind to post some pictures of your BIOS settings? [/QUOTE]

I wonder if this is possible on a remote system. Can a EUFI system make BIOS settings accessible to the Borgmeister?

I didn't know it was a remote machine. Just ask your friend to take some pictures with a digital camera. Also take a snap of windows manager, we want to see which services are on and off. On my laptop cruncher only 40 services on, the rest is off including windows updates, windows searcher, NET [I]Framework, [/I]etc...off the ones which consume a little of cpu. (list services that are automatic on startup)

Does NOT NOT NOT look good.

Actually, looking at the numbers, there might be a way to greatly boost your throughput. Try running 1 LL test using 4 threads (or even 3 threads). That might actually give you more throughput than running 2 LLs x 1 thread each (hopefully, closer to 3 LLs).

1 LL 2 threads gives a throughput of 1000/15.3 = 65.3 iter/sec, which is only marginally better than 2 LL x 1 thread (62.4 iter/sec). Nonetheless, that is probably the way to go. While 3 threads have better "best-case", it's average case is really bad.

These three lines effectively demolish any temp throttling hypotheses. When the entire FFT fits within the cache (or nearly so), you get a thruput of more than twice that of the 4 test case.

Or sadly is the best overall gimps benefit to run 1 LL at 20ms for 3548fft and tf or ecm on the other 3 cores. Currently testing with # LL and 2 ECM

It's either temps or memory by now...

Oops should say 2 LL and 2 ECM (Small).
I already know that adding 2 TF does NOT impact the LL time by more than a percent or two. I was doing 50xxx TF to 61,62 bits on 2 cores when this PC first turned up. These assignments were giving me 7 GhzDays / Day / Core.

I find that TF assignments for bit levels below 65 are quite generous. So I know that if I let it do the current TF assignments that PrimeNet would hand out (66 - 72 bits) it would not be quite that productive. But it will be a LOT more than 2 ... see next point.

I have noted so far that it completes 2 ECM (one each from core #1 and #3) in 4:30. That works out to 2 GhzDays / Day / Core. I have 800MB RAM of the 4000MB total allocated. I think this should be enough for ECM Small even if both are in Stage 2.

I need a day or two to determine if this slows down the LL workers.

If it does cause a LL slowdown I'll try 1 TF and 1 ECM.

Have you checked the temperatures yet? :smile:
