CPU downclocked in BIOS

[GLOBALruler]

Hey there,

I recently changed the motherboard in my system to Intel DG965RY from DG33BU.

Now I experience significant shutter in my games or even in windows. I checked CoreTemp, and noticed that the CPU was down clocked to 1.6Ghz. My processor is an Intel Q6600 2.4Ghz. Temps are ok, 50-60 idle, 70-75 under load. Also checked in BIOS, processor speed is listed as 1.6Ghz. I tried resetting CMOS, turning off Enhanced Intel SpeedStep but no luck. Is something wrong with this board or something else is wrong? The reason I changed this mb was because of my GPU (R7 360) which didnt work in the previous one.

Thanks.

It's simple really : That MB doesn't support Quad Core's.
Here's compatibility list : LINK.

Not supporting dosent necessarily means it would down clock the CPU. Could you explain this a bit more please?

If the motherboard doesn't support the quad-core, it may not set the proper parameters for it. You could check and see if there's a BIOS update for it, or you could try to manually set the clock speed in the BIOS.

It dosent allow me to manually set the speed. BIOS is updated to the latest version for this board.
