was one core maxxed though?
this is what an application that can max out a box should look like..
This machine is processing half a billion records per hour, problem is its load balanced across 6 identical spec machines all doing the same to the CPU
Using 2x Quad-Core Intel® Xeon® Processor E5440 (2.83 GHz, 1333 MHz, 80W)

We cant change the architecture, otherwise I suggest superdome running windows
It was running on one box before and the code has just been re-worked to support the load balancing - a ten hour processing job should now take less than 1hr..
Can easily add more nodes in to the cluster DL360 G5's and deliberatley installed them in an empty rack

The first time that ran 1:10 had about 80% on one core and the other was at about 20%.

you could play with affinity and setting the priority but I doubt it would gain much.. recoding superpi would produce better results..
Wonder if our cluster could be made to do that

Settled on 4.24GHz in which it is stable running maximum CPU usage for an hour and gaming. CPU temp <60 C. Overclocked the 8800GT as well by 50MHz on each. It is 11 seconds at this speed on SuperPi. At that speed I can also run all the fans nice and quiet.
Plays Crysis smoothly with everything on High at 1280*768 on my projector Although the projector is only standard def and scaling it, it looks better than it does at its native 848*480.
So, quite pleased with the new system - until it melts

Just air cooling - arctic freezer 7 pro... settled on 4GHz at 8x500FSB in the end - 11 sec Pi 1M, CPU temp 45-50C under load. I can run the fans really quiet too.
8800GT is o/c from 600/1800 to 640/2000.

John what mobo are you using?
I can get the CPU to go over 4GHz (got the e8400 as well) but the memory only limits to 1:1 on clock speed, so my DDR2-6400 lets me down - right now I am happily running the e8400 at 3.6GHz cos that's all the memory will let me.

Asus P5K-E. Crucial Ballistix DDR2-6400 - overclocks happily to 1000MHz at 5-5-5-15 timing, and the motherboard seems to laugh at 500MHz FSB also.
I found out that the motherboard bios reports the case rather than the core temp which is about 15C higher. I downloaded core temp and ran it on Orthos stability test.
Based on those results I am now on 445*9 (4005MHz) with the CPU core running 1.40V under load (set to 1.425 in the BIOS). CPU runs in the low 60s Celcius which I gather is sensible from my searches. It runs a little hotter running 500*8, although still stable. Extra gains from here on this cooling just result in a lot more temp for 5% performance gain - not worth it long term.
I have done more testing on the graphics card, 630 and 1960 MHz for the core and the memory. Any higher and it artifacts under load after a little whilst. The overclock of the graphics card added about 6% to the frame rate in Crysis.

I just bit the bullet and dumped my noisy Western Digital Caviar (christ, noisiest drive I've ever had - barring the Hitachi I have at work - but at least that is noisy because its fast). All in favour of two Samsung Spinpoints which are faster and will be running on a RAID0 array (with the WD drive as an archive drive for backup).
Is there any decent benchmarking to see how much of an improvement it is? (did a quick run with HDTune before I configured them for RAID but that doesn't really show much).
May start a seperate thread to see how fast people's hard disks are

The reason my laptop sometimes runs over a minute and other times at 38s is that it throttles back the processor to 800MHz even when on AC power unless it seems a large processor load. SuperPI seems not to be enough, so it runs at half speed! I have been searching and tried the always on power mode but it still runs slow. There is no option on the BIOS. I am just wondering if the thing would feel a bit snappier when on AC power if I found the right setting.

^ Downloaded notebook hardware control and that does the trick (except it makes the fans run a lot more of course).
Edit - it has a nice setting where you can get the CPU speed to increase at lower loads when on AC rather than battery. It runs 38s in SuperPi by quickly raising the clock speed but doesn't make a lot of noise and heat the rest of the time.

It can be controlled in Vista via advanced power options when you can set the minimum processor speed for both A/c and battery operation (althougth it was buggy in early versions - automatic updates quickly sorted that).

Thanks, I didn't think to boot into Vista, I installed it and hardly use it. Arguably that is because my CPU would feel like it was running at 800MHz even when it is running at 1600MHz
On my 1GB laptop I can boot into Windows and have 600MB+ RAM available, it doesn't bash the drive much at all. Vista really wants 2GB and I would need to throw the 512MB sticks away.
