Q6600 running at 3.2GHz and RAM at 400MHz - tools for testing

Could someone please let me know what the equivalent speed / performance of the Q6600 at 3.2GHz would be compared to the newer CPUs?

Secondly, I have seen people running burn in tests to check how stable their OC is, something about "prime" (I suspect it calculates prime numbers), could someone please point me to it?

Prime is good program but also use OCCT test too sometimes prime will pass and occt won't and vice versa. I would suggest running OCCT for an hour then let prime 95 go overnight. As far as your q6600 standing up to newer CPUS it dosent it is a 65nm CPU which was good when it came out but like all CPUS that dont last long compared to an I5 the I5 will smash it.

For the OC Q600 at 3.2GHz, what is a good temperature to reach when running constantly at 100% all CPUs, eg OCCT ?

How do you get it to "stress" the CPU? I suspect simply repeating a tight loop of instructions is not enough and something more sophisticated is needed to heat up or utilise various areas of the chip?

Run Prime95 Small FFT test or use OCCT as listed in the above posts, you should try and keep it below 65° C.

Please read the Overclocking guide, it will answer your questions.

I have read the guide. I have successfully overcloked the Q6600 by increasing the bus frequency to 400MHz so the chip runs at 3.2GHz. RAM runs at 800MHz. I did not modify any voltages except the RAM which I put up to 2.1V. I am not sure what the CPU and other voltages are, perhaps the motherboard does it automatically, perhaps they are running at stock values. Chip runs cool at about 35C with no load and 50C with full load. I ran Prime95 for a couple of hours and it was fine.

I have also overclocked the i5 750, I raised the BCLK to 160MHz from 133MHz, running the RAM at 1600MHz (10:1) and using the RAM's own SPD profile, I believe voltage was raised a notch, but all automatically. CPU multiplier set to 21, so I am getting 3.35GHz clock on the CPU. Chip runs at about 30C with no load and 50C with full load, again I did not go anywhere near any voltages.

Is there a well known benchmarking tool that I can use to compare the performance of my two systems against tom's published results? It seems that PC Mark that tom uses only runs on Vista.

There are a number of tools to test your system the main ones will be PCmark 06, PCMark vantage 3Dmark, Some use Passmark too my favorite is PCmark.

All on Windows 7 / Vista, nothing for Windows XP. Why such a dependency on the OS ?
