What CPU is this?

[idata]

I have a Dell PowerEdge 1850 with a Xeon 3.0Ghz/2MB Cache/800Mhz FSB CPU/MPGA604 socket. The system has an E7520 chipset. I'm trying to figure out what model the CPU is so I can buy a faster version of it, but I'm hitting a wall.

From what my OS tells me, this is an EM64T processor (because it's booting an AMD64 kernel), and it supports what I believe is Hyperthreading (as opposed to dual cores). I believe it supports Hyperthreading because it shows up on my FreeBSD system as 1 physical processor, with one core, but two logical processors on the one core:

CPU: Intel(R) Xeon(TM) CPU 3.00GHz (2992.71-MHz K8-class CPU)

Origin = "GenuineIntel" Id = 0xf43 Stepping = 3

Features=0xbfebfbff

MOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>

Features2=0x641d>

AMD Features=0x20100800

Logical CPUs per core: 2

real memory = 1073479680 (1023 MB)

avail memory = 1024192512 (976 MB)

FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs

cpu0 (BSP): APIC ID: 0

cpu1 (AP): APIC ID: 1

I've checked http://ark.intel.com/ProductCollection.aspx?familyID=594 http://ark.intel.com/ProductCollection.aspx?familyID=594 but I end up confused: The only CPU I see that matches the speed, cache and fsb is http://ark.intel.com/Product.aspx?id=27094&processor=&spec-codes=SL7ZF,SL8P6,SL8ZQ,SL944 http://ark.intel.com/Product.aspx?id=27094&processor=&spec-codes=SL7ZF,SL8P6,SL8ZQ,SL944 but there are a couple of problems with this find:

1) It says this processor is a 64-bit processor (Intel 64) and not EM64T like the one actually installed in my server,

2) It says this processor doesn't support Hyperthreading, but the server is doing hyperthreading.

Can anyone help me identify my processor?

BTW: I can't use any of the downloadable tools to identify the processor because the box does not run Windows and it's a production server, so I can't easily shut it down and boot to a Windows LiveCD or something capable of running a CPU ID util.

Thanks in advance.

Have you even looked at the inside of your Dell?

http://dcse.dell.com/ifr/PowerEdge/PE1850/systemboard.asp http://dcse.dell.com/ifr/PowerEdge/PE1850/systemboard.asp

You have Dual mPGA604 (604-pin) sockets unless one is not in use and you only want to upgrade one?

What does CPU-Z say?

Yes, I know it had dual mPGA604 sockets, but that in and of itself doesn't help figure out what processor I actually have. Lots of different processors use that socket.

I know the specs. I posted them in the original post, but I don't know what the model code or part number for the processor is, so I can go order another one (or a faster one) until I do.

Like I said in my original post, I'm having trouble using Intel's product documentation because their documentation is inconsistent with what is actually installed (Intel 64 vs. EM64T, HT vs HT not being supported, etc). I don't know if I'm looking at older documentation or what, but all I know is that I have no idea how go to my online distributers and order another one.

EM64T is Intel 64

You don't have HT you have 2 CPUs with one core each.Going by this:

http://www.dell.com/downloads/global/products/pedge/en/1850_specs.pdf http://www.dell.com/downloads/global/products/pedge/en/1850_specs.pdf

Up to two single-core 64-bit Intel® Xeon™ processors at up to 3.8GHz

or up to two dual-core 64-bit Intel Xeon processors at 2.8GHz

Thanks for the clarification on Intel64 vs EM64T.

I don't have 2 physical CPUs installed in the system, I have only one. I cracked open the case yesterday in order to determine the socket type and paid special attention to the well engineered plastic insert they put into the empty CPU socket.

So now you see my confusion. It can't be dual core because it's 3.0Ghz. Intel's documentation says the closest CPU match to mine, based on specs does not support HT, but my system shows two CPUs...

[idata]

No the system you are using thinks its got 2 CPU's...this is what you get for not running Windows.

Can you even see two CPU/cores in like a task manager?

I came across a similar problem and concluded it is:

Single core, two threads (HT).
