Intel Pentium 4 Hyper-Threading

by jamestony / March 18, 2005 3:13 PM PST

I just did some research on the Intel website regarding my Intel Pentium 4 Processor number 519 which comes with the Emachines T5026. It said that Hyper-Threading was turned off for this processor. Why? Does anyone know how I can turn the Hyper-Threading on or do I need a new motherboard? Thanks in advance.

Another probable solution??
by jamestony / March 18, 2005 7:53 PM PST

I have the Intel Desktop Board D915GVWB, would this board support a pentium 4 hyper-threading cpu or better yet maybe one of intels new 6xx cpu for 64bit compatibility. Maybe I should just swap out the motherboard for a aftermarket motherboard with a new cpu. What 3rd party motherboard would fit inside my emachines T5026 case? Thanks again for all the help.

Still need a new CPU.

The CPU you have is not the HT variety. shows this board to have the needed CPU support, but this move is going to be expensive as you'll need new RAM as well as the CPU.

I wouldn't do this with the 64-bit wave approaching.

There are some 533 MHz FSB with Hyper-Threading
by John Robie / March 19, 2005 2:36 AM PST

I can see where you may have thought your PC could have HT by looking at this link indicating HT tech suported the 533MHz system bus: 3.06MHz. However, scrolling down, your 915GV chipset is not listed as one of those with HT.

They list these Intel desktop chipsets with 533/400 MHz as having HT:

910GL, 865P, 850E, 845PE, 845GE, 845GV, 845E, 845G

I also note your Pent 4 processor number 519 is not listed with those that have HT support.

Special CPU
by jamestony / March 19, 2005 2:01 PM PST

It looks like to me either this CPU number 519 is no longer in production right now or is a special cpu made just for Emachines with a lower FSB. It seems as all the socket LGA775 are 800fsb when mine is only 533MHz. And the lowest CPU number I can see is 520. Looks like I'll need a new CPU,motherboard, and ram by 2006.

eMachine T5026

My brother has this computer, which basically makes it half-mine as its in my house. I plan to upgrade the motherboard, processor and ram when the dual-core Pentium D comes out.
