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.

BIOS

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

CPU-Z

This is from the advert where I purchased the CPU:

Status Launched
Launch Date Q1'10
Processor Number i5-760S
# of Cores 4
# of Threads 4
Clock Speed 2.53 GHz
Max Turbo Frequency 3.33 GHz
Intel® Smart Cache 8 MB
Bus/Core Ratio 19
DMI 2.5 GT/s
Instruction Set 64-bit
Instruction Set Extensions SSE4.2
Embedded Options Available No
Lithography 45 nm
Max TDP 82 W
VID Voltage Range 0.6500V-1.4000V
Recommended Channel Price $279.00

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.

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.

Turbo is only used with high CPU load.

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?!?
