Unmarked intel i7 CPU?

Recommended Posts

Posted · Original PosterOP

My brother gave me his old PC a while back which he bought from another guy online. The CPU is an intel i7 with I think 4 cores, although on CPU-z and system properties there is no model number, it just says Intel i7 @2.67ghz. I removed the cooler and there is no model number or at least not anymore, copper is exposed. How do I work out what CPU this is? Very faintly at the bottom of the chip I see a number: e44476 61 101. This is all that I can go off considering this was from my old PC which is now broken although the CPU is still in shape. Note that this CPU is not compatible with my new PC (msi gaming 970). Any ideas what CPU this is/was? Is there such thing as a unmarked i7?

If its 2.67 its an i7-920


Thats that. If you need to get in touch chances are you can find someone that knows me that can get in touch.

Can't tell if it's a es midel or the top part is just grinded off, but Intel does have rare CPU s where the makings are stamped on twice or none at all.

Looks like the IHS has been lapped.

Looks too good to be lapped. The shape is too symmetrical. Must be a copper pad or Intel made it like that on purpose.

If you lap it right you can achieve an almost perfect surface.

It is probably an i7 920. Perhaps an ES version if CPU-Z isn't playing ball with it.

Not talking about the surface, just look at the outline  where the copper is exposed, on the left edge and the right edge. I doubt a human hand can achieve that level of precision, while using a grinder.

I don't know anyone who uses a grinder to lap, most people use progressively higher grains of sandpaper, attach them to a sheet of glass, and then use that. If there were variation on the height of the IHS in that pattern, then it would look like this. This definitely looks like lapping.

Regardless, as far as I know the first gen i7's specifically the 920 is the only i7 I can think of that came at 2.67GHz, from the factory.

Umm. there is no pic.

So using sandpaper can achieve this type of precision?

For speed, yeah i7 920 default clock was 2.66GHz.

technically sandpaper isn't lapping. lapping is when you put like a grit paste between two surfaces so they are matched perfectly.

If the height variations in the IHS were in that pattern, and they just didn't take the time lap it completely smooth, that is exactly what it would look like.
