Identifying a CPU type

[TheLemming]

Hi guys,

Small appeal for some advice if anyone is able to help me out?

I'm having a bit of a disagreement about the CPU fitted to my machine, with the systems builder claiming its a dual core while I'm swearing blind its not. He's a friend so I really dont want to have a big arguement, just clear it up as quickly as possible while trying not to have a falling out...

Control Panel reports an Athlon 64 3800+, CPU Z reports an Orleans core socket AM2 3800+. AFAIK and AFAICS these are single core chips.

Beyond the lack of multitasking performance and inability to set a core affinity in task manager, is there a definitive method of establishing EXACTLY which CPU is running (beyond removing the HSF and looking at the serial numbers etc?)

CPU-Z is usually on the ball when it comes to recognising processors, so I'd be inclined to believe what it's saying. Though as a second-opinion, what does the BIOS think?

[V8 Animal]

I reckon it's a single core.
As twister says look on the boot screen it will tell you there look for 3800 it will have X2 after it if it is but i doubt it.

[TheLemming]

Defnitely no use of "X2" anywhere I've been able to look, including the BIOS.

I'd believe CPU-Z, but maybe try Everest and a few others to back up what you think...
Didn't realise there was such a thing as a <4000+ dual.

I'd look on the boot screen and see what it says, as has been suggested.
CPUID should do the trick as well.
Device manager should also report what it thinks the cpu is.
Task manager should show two processor utilisation graphs; this is the quickest way!

Might be two 'virtual' cores like the Pentium 4 D IIRC? Once you know the model number, you can google it. Not so hot on the AMD side. Intel FTW1

Not if Windows has been installed using the uniprocessor HAL (perhaps by restoring a system drive image that'd been built on a single-core PC), or if Task Manager has been configured to show a single graph for all cores...

Unlikely, but possible

Orleans is definately a single core chip

Read the first para headed "technology."

I've got an AM2 dual core AMD Athlon 3800+ and cpuz reports that as a ADM Athlon(tm) 64 X2 Dual Core Processor 3800+ Code name Windsor.
HTH.

Yep, Windsor is a dual core 3800+ x2 whereas the Orleans is a 3800+ single-core.

Bingo - the smoking gun

Thanks very much for the help guys.
