Hyperthreading technology question

totokan · Post by **totokan** » Sun Oct 30, 2005 6:56 am

Well, once again I was talking to tech support about my mobo. He asked me about the processor, a 2.66ghz p4. It has a 1mb l2 cache, and is lga 775 (and 533Mhz fsb). He told me that if it has a 1mb l2 cache, it is a hyperthreading processor. It says nothing like this on the box, so I was wondering if anybody knows if this is true. (Since tech support always has varied opinions on what's wrong)

I dont think your CPU supports HT. The system bus speed and processor speed sound like their about 3 years old (like my Gateway). HT didnt come out til maybe 2 years ago. And if you have a P4 sticker on the case and it lacks the "HT" in the lower right corner then it doesnt support it.

If your still unsure about it, you can check Intel's site and see if there is a way to verify if your CPU has that feature. I'd suggest using Windows but I dont know if Microsoft released a package for windows that supports that technology.

He said LGA 775, though.

LGA 775, a.k.a. Socket T, is a pin package that is newer than 2 years. The processor is new enough to have been built with the technology. Also, the boxes, when it comes to HT, CAN be ambiguous. When looking for HT, look for two diagonal orange marks on the box corner, and it MAY also have the phrase "Supporting Hyper-Threading Technology" on it.

The website I use for looking up processsor specs (Which is VERY comprehensive, covering from the 486 up to the most modern processors), says that these support HT.

Pentium 4 505 - 2.66GHz (133x20) - 1.4v - 1MB L2 (Prescott - Socket T)
Pentium 4 505J - 2.66GHz (133x20) - 1.4v - 1MB L2 (Prescott w/ NX bit - Socket T)

"The Socket T Prescotts with 5xx designation are desktop varieties and support Jackson Hyperthreading."

look for the two logos on the mobo box and the cpu box if you have this one:
or somthing like it

you don't have hyper threading, but if you have this one:

or somthing like it, you have hyper threading

Sounds like yet another attack-of-the-retarded-tech-support-people incident.

The three CPU's operating at 2.66GHz and using an LGA775 socket are: Pentium 4 505, P4 506, and P4 505J. All three have 1MB L2 Cache, and 533MHz front-side-bus. All three do Not support hyper-threading.

It is true that the Prescott core was designed with Hyper-Threading capabilities, but, as with almost any tech industry item, Intel went and "turned it off" in order to sell a "budget" processor. Silly Intel.

thanks. By the way, to everyone saying look on the case, I bought it 2 months ago on newegg (and still have yet to boot into windows/linux).
