QX6700 and XP Home - Will it recognize all 4 cores?

[Hulk]

If I remember correctly I think as long as there is one physical processor socket XP Home will fully utilize whatever is sitting in it right?

 

[Stumps]

Umm I'm not sure, I wouldn't think so but then again I could be wrong, it might support multiple cores on a single CPU.

My QX was booting up with all 4 cores reconized b4 the PSU blew. Dont worry unless your BOARD cant support a kentsfield it will pick it up in XP.

Correct.

As a matter of fact, I installed XP home on a dual slot1 P3 1ghz Compaq server, and it saw both cpus Was hell getting the raid going, but it worked out ok. Finally got my s2k3 license, so it's proper now.

As to Core2Quad, no prob w/Home

XP Home runs on one or two processors, core it just treats as sub-units kind of like HT on the xeon or pentium 4s in task manager.

actually i saw 4 logic cores on the windows task manager uner performance and cpu history. There was 4 boxes. CPU-Z reconized it as a kentsfield and coretemp showed temps on all 4 cores. :\

I cant tell you anymore more then that. Other then having prime95 run 4 times is a PITA because u need 4 different sub foldiers, and i think my orthos is messed up because its only picking up 2 out of the 4 cores, but it picks up both cores on my opty. Blah ... maybe something is wrong with the settings.

Anyhow i wish my QX was up so i could just take a SS for ya. Im still in debate on if i should go OP1000 from silverstone or PCnC 1Kw. There both great PSU's for quad core. Blah also i took the thing down because i reciently found out that an APOGEE will pwn a STORM rev.2 on a Quad core by almost 3-4C even with high flow :\

Couldn't you just run a stress program and open up task manager and check for 4 logic boxes all with varying degrees of spiking activity? If you see activity in all 4 boxes then the OS is utilizing all 4 cores. If you only see two logic boxes then you know that XP home is limited to utilizng only two of the cores...

Okay cool thanks for the replies.

I meant two physically seperate processors. It'll have no problem addressing additional cores within each processor. I can't remember where it tops off but it is not limited to two cores, just two socketed processors.

This isn't new - P4D xtreme's had 4 logical cores so XP's had to do this for a while.

 

[Roguestar]

Yes, but they had just two cores and were hyperthreaded so appeared to do the same work as four cores (but actually weren't nearly as good).

I wonder if quad core is hyperthreaded, wouldnt that allow 8 "cores"?

 

[Roguestar]

I don't think they've used hyperthreading since the Pentium 4, so if it's not in this generation of the Core microarchitecture it'd be another while yet before we see it. Besides, I daresay there isn't /much/ need for that much threading going on in the /average/ person's PC (even the average gamer).

Yes, it would produce 8 logical cores. Future quad-core Xeons may demonstrate this.

The Pentium Extreme Edition chips (which are based on the Pentium D) support Hyper-Threading. Nearly all modern (post-Foster) Xeons do, with the notable exceptions of Sossaman and Woodcrest.

I'm not aware of any current non-Netburst products that support Hyper-Threading, though.
