HI, everyone

if your mainboard supports ht then u can plug the cpu and see if it works.

The Pentium 4 3.06GHz 533MHz FSB Northwood (non-mobile version) does support Hyperthreading. Whether or not you can put it in a desktop motherboard depends on whether or not it's a full P4 or a P4-M (mobile version).

The P4-M did go to 3.06GHz so you need to verify whether or not the CPU you have is a P4 or a P4-M. If it's a P4-M then it depends on which version you have as to whether or not it supports Hyperthreading.

Also, if it's a P4-M and even though it's a 478-pin package, I don't believe it's pin compatible with desktop Socket 478 motherboards.

ok, i've tried it in a motherboard and it worked well except that its not reading at 3.06GHZ its reading 2.6ghz i think

It's probably a P4-M. Does it have a heatspreader (metal cover) or can you see the core? If it has a heatspreader it's a P4. If you can see the core it's a P4-M.

Since it's running at 2.6GHz I have a feeling it's a P4-M. They have features that slow down the CPU to save power. The BIOS of a desktop motherboard probably doesn't have the features necessary to run it at full speed (although you'd think it would by default rather than running at the slower speed).

well u can always check the taskmanager under performance tab. then under cpu usage history, the graph for it. if the graph is split into 2 then is HT, if its just 1 big graph then it is no HT.

[nmX.Memnoch]

That only works if Hyperthreading is enabled in the BIOS and the correct HAL is installed in Windows.

@ideas: What information is printed in the CPU itself? There should be just a bunch of numbers.

the exact details on the CPU


Intel M © '02
Pentium ® 4
3.06GHZ/512/533

SL77P MALAY
L412A948


M413C746
1009

After doing a little searching I found that the SL77P is part number RK80532HE083512. According to this page, it does support Hyperthreading.

It is a Mobile Intel Pentium 4 so your mileage may vary getting the CPU to work properly in a desktop board.
