q6600 showing only 2 cores in CPU-Z

[Koolaidman23]

I just installed this processor as an upgrade to a e2180. Here is an excerpt from CPU-Z:

Processor 1 (ID = 0)
Number of cores 2 (max 4)
Number of threads 2 (max 4)
Name Intel Core 2 Quad Q6600
Codename Kentsfield
Specification Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
Package Socket 775 LGA (platform ID = 4h)
CPUID 6.F.B
Extended CPUID 6.F
Core Stepping G0
Technology 65 nm
Core Speed 1600.0 MHz (6.0 x 266.7 MHz)
Rated Bus speed 1066.6 MHz
Stock frequency 2400 MHz
Instructions sets MMX, SSE, SSE2, SSE3, SSSE3, EM64T
L1 Data cache 2 x 32 KBytes, 8-way set associative, 64-byte line size
L1 Instruction cache 2 x 32 KBytes, 8-way set associative, 64-byte line size
L2 cache 4096 KBytes, 16-way set associative, 64-byte line size
FID/VID Control yes
FID range 6.0x - 9.0x
max VID 1.325 V
Features XD, VT

Notice that it only shows 4 MB of L2 cache. What am I missing here??

GA-P35-DS3L
Q6600 stock (for now)
4 GB A-DATA DDR2 800
Earthwatts 500-D

btw, I did uninstall each core and re-install in vista. Device Manager is now showing all 4 cores, but CPU-Z and RealTemp only show 2. Everest shows one core. Also, I did reset the CMOS before installing the processor.

It could be an old bios that doesn't support newer cpus. Look up the bios information in Gigabyte's site, and update if needed.

I have the newest bios... I was going to buy a q9550 so I flashed it a couple weeks ago.

Check to see if you have something like 'Core multi-Processing' option (*edit* - in the bios), which could be disabled, and why perhaps CPU-Z sees only 2 of the 4.

Are you running on XP SP2 or later? Early OS don't recognize quad.

I am using Vista 64.

I also bought a seagate 640 gb 32 mb cache HD. I just reinstalled windows onto it, and all is well. Realtemp shows 4 cores, and so CPU-Z shows 4 cores and 4 mb x2 of cache. Temps are low with my arctic cooler 7... all four cores are between 29 C to 34 C.

Now to overclock!
