 Posted: Thu Oct 09, 2014 3:40 pm Post subject: Unknown ID for Core 2 duo/quad |
 |
|
Hi,
I just recently inherited a EVGA 750i SLI Motherboard that did not boot. It was free so i didnt really care, and i pulled off the Intel Heatsink at saw this below
--see picture now--
It seems to be a 775 core 2 duo/quad, but i cannot tell because the top of the heat spreader has been ground down enough to show its copper base. the only ID it has is on the side with the code:
2L640526
A0173
Question 1:
Does anyone know what processor this could be? (i would have put it into another motherboard to test and check, but the other 775 board i have is a 945G chipset)
Question 2:
What is the point of grounding down less than a millimeter of aluminum or whatever metal covers the copper on the heat spreader? The heat conduction shouldn't noticeably change, so why?
Thanks

People sand the heatspreader flat (it's known as skimming) to provide a flatter surface and better contact with the cooler. It's usually only done by people who are overclocking and wanting the best performance they can get.

Ah OK, that makes sense, but is there anyway i could be able to check which CPU this is? What do the letters/numbers on the side correspond to? I have heard that it is possible to check which model the CPU is according to the heatsink that came with it. Is that true?

Arrangement of components on the other side can let you identify core count and cache size but not speed. You can find information about this at http://cpumuseum.jimdo.com/guides-tutorials/socket-775-identification/.
Then one good option is to try to find another motherboard and boot that CPU on it to both test and identify it. |

Ah thanks, The CPU seems to be a Conroe B2... If i am lucky, it might even be the X6800! (ha ha) I am going to ask my friend if i could borrow his 775 board to check. But i think his has a Nforce4 chipset. Will Conroe work with that?

An NForce4 based Intel board will only support Pentium 4 chips. google NForce4 for more info
