Need help Guys !

Okay while oc my dell xps m1710 I noticed after installing a new temp monitoring application called "Core Temp" my Core 2 Duo T7600 G is being read as a "Mobile Intel Core 2 Extreme X7900 (Merom)

Is my core 2 duo t7600g magically upgraded itself Or has intel secretly sold me a core 2 extreme rebranded as a core 2 duo Sure runs like a Black Edition Processor !

Any advice guys ?


Attachment of readings above

 

it looks like the x7900 was just an OCed t7600. see here. core temp is just reading it as the later chip for whatever reason.

 

download HWinfo64 from my sig below and this will tell you exactly what is loaded.

 

T7600G is socket M

X7900 is socket P.

They are not interchangeable under any circumstances.

The socket type used on your machine will determine the answer very quickly.

 

Yeah as ajkula66 has stated, Socket M is completely different than 1st generation Socket P. Plus X7900 is 800 FSB, wouldn't be compatible with 667 FSB Core 2 Duo chipsets.

 

According to this review:

Dell XPS M1710 Review (pics, specs) | NotebookReview.com

these machines were shipped (amongst other options I guess) with a T2600 which is a Socket M, Core Duo (Yonah) CPU.

There is no way of getting a socket P CPU to work in one of them, regardless of "Merom" designation for both T7600G and X7900, they are very different animals altogether.

FWIW, I've thrown a X7900 into a ThinkPad T61 which sports a socket P motherboard, and 800MHz FSB. Matched up with nVidia NVS140M. I could've used the heatsink to fry eggs on it...

 

take it easy, you two. if you actually check out the ark comparison i linked, the T7600 also used the same socket as the X7900. there were apparently three versions of the T7600 and a quick google search shows the XPS M1710 could have been originally configured with a T7600, not the the T7600G--which might be relevant if this M1710 was configured with the version of the T7600 that used the same socket as the X7900. the only weird thing is that wikipedia lists the non-socket M version as having used socket FCBGA6, which is the "BGA version" of socket P...? see here. or something. it goes a little beyond my understanding of sockets and pins and balls, etc.

so again, OP, it looks like the X7900 was just an OCed/rebadged version of the T7600. core temp is reading it as the later chip for whatever reason.

 

Which is what I said to begin with...

It's a different chip altogether. The only thing that T7600/G and X7900 actually share is the Merom designation.

 

you caught me pre-edit. should have read: "if you actually check out the ark comparison i linked, the T7600 also used the same socket as the X7900"--which isn't socket M. i confused myself, sorry.

 

Happens to the best of us, myself included...

I'm certain that OP now clearly understands where he stands with the help from all of us, which is the only important thing...

 

i don't understand though. i see that the T7600G uses socket M. i also see that the T7600 uses the same socket as the X7900. so far OP's actual question hasn't been answered. he was under the impression that he had a T7600G, but a monitoring utility is reporting a X7900. why? i don't think the OP has received any truly accurate information yet...

 

Wherever you've seen this info, it's incorrect.

T7600 - as well as T7600G - is socket M.

X7900 is socket P.

Period.

I've seen various software report all types of nonsense over the past 15 years. The *real* answer will be found in BIOS.

In OP's case, it will be T7600G since his machine would not boot with a X7900, no ifs ands or buts.

 

so which version of the T7600 used the same socket as the X7900? supported socket PPGA478, see here.

agreed. there may still be an explanation for the nonsense however.

 

None.

You can't go by that on laptops, not all the time anyway.

While a socket M CPU will physically fit in a socket P housing and vice versa - hence the PPGA478 designation - they are not compatible or interchangeable.

If you take a look here, PM780 (SL7VB) used in an ancient T43p that I'm typing on right now shares the same PPGA478:

ARK | Intel® Pentium® M Processor 780 (2M Cache, 2.26 GHz, 533 MHz FSB)

As does the vintage P4M (SL6VC) found in one of my A31p units:

ARK | Mobile Intel® Pentium® 4 Processor - M 2.40 GHz, 512K Cache, 400 MHz FSB

I'm certain that both yourself and the OP understand the difference now...

 

yea, i suppose. happy to parse that out with you.
