Did I buy a Core 2 Duo?

[davethe11]

hi there

I bought an E2200 from ocuk (link)

The page says its an Intel Core 2 Duo E2200, I bought it because I heard that the Core2's overclock very well. Looking at the packaging of the E2200 it doesnt say core2 anywhere, only "Pentium Dual-core Processor". I've looked at pictures of more expensive Core 2's on ocuk and they clearly have "Core 2 Duo" on their box. Am I missing something here?

[edit] also, cpuz and all other applications that report cpu spec only state Pentium Dual Core, never Core2?
[edit2] my laptop has a core 2 and cpuz correctly reports this
[edit3] actually, the box in the picture in the link says "core 2 duo", the box that my cpu came in doesnt!

thanks guys, info much appreciated. Regarding overclocking this cpu, I currently have it at 266 x 10 (this allows me to set my crucial ballistix tracer to 1033MHz), I thought that increasing the multi to 11 (giving me 3GHz) would be ok but the system became unstable and restarted after post. Are there cpu options in the bios I should disable in order to achieve the higher speed? Friend of mine has a core 2 1.8GHz overclocked to 3.2GHz on stock vcore and on air with good temps, I was keen to keep the vcore down for cooling reasons but when I found that the cpu was labelled as a Pentium this made me think that it wasnt a Core 2 thus the problems overclocking. Any help would be much appreciated.

that would be fantastic, thanks mattyrigby00

i have mine running at 266 X 11 and its rock solid, ill take a pic of what my bios settings are and post it here. it can run higher but i prefer just 266x11 for normal use because of the volts needed to run higher

thanks for that matty, much appreciated. Unfortunatly I'm on an American Megatrends bios so its different settings for me, but will set my vcore as you have and give that a go.

thanks for all your replies, when I purchased it I was aware of the 1MB level 2 cache, and the clock speed. If this is the only difference between the E2200 and a 2.2GHz core 2 duo, then I've got what I expected to get so no problems there. The main problem is that I can't overclock this chip, I've got it Orthos stable at 10x266 (2.66GHz) but have tried 11x266, 10x270, 6x500 etc and no joy. I'm using crucial ballistix 1033MHz which I underclock to get the cpu stable, but I'm not getting anything. I've set the vcore up to 1.3V and no joy. Like I said earlier in this thread, my friend has a core 2 duo 1.8 overclocked to 3.2 on stock volts and cooling with good temps, I expected my overclock to be a bit easier. I've disabled spread spectrum for both the cpu and the pcie bus, but left most other settings on default. I've manually set the FSB NB strap to different values and no joy. Can anyone suggest what else I can try?
