Windows 7: Non-existant i5-760S CPU ?!?!?

I can remember that there are definitely the numbers "760" on the chip itself - I can't remember if there is an S or not. But I'm not about to remove the heatsink to find out.

Here is the BIOS screen describing the CPU - it calls it an "S 760". Note the turbo frequency is the same as the normal frequency. On other machines I see these two numbers being very different. I've not overclocked anything, and I've turned on all CPU features.

And here is a snapshot of CPU-Z, showing it running at 2.53GHz, when all cores are fully utilized.

Go to Advanced CPU Core Features and set everything to AUTO, if not set already.

Already set to auto.

And my idea of upgrading the bios from 3rd latest version to latest version didn't help either.

I guess this board just doesn't support this CPU fully. Ah well, it is a budget machine.

Have you tried loading the defaults in the BIOS?

Yes.

I noticed that if I go into the overclocking options, that I can only set the CPU clock multiplier at up to 19. Before, when I've looked in a BIOS, the multiplier can be set at at least up to the multiplier required to get the turbo on. Could this board not support multipliers over 19?

Gigabyte's CPU support list for the board:

GIGABYTE TECHNOLOGY Socket 1156 - Intel H55 - GA-P55-US3L (rev. 2.3)

The 760S isn't listed, which seems odd.

I have it fully loaded on 4 cores using BOINC.
Turbo will only boost one processor if the others are basically idle. It can't boost if all 4 are loaded or the processor would get too hot. T test if it is working you have to run a single processor and load only one processor.

That's because there is no such thing as a 760S according to Intel! I have a phantom CPU! Maybe this was a small batch made and they discontinued it?!?
