Too many processors

[Guest AnytimeAnywhere]

I have a Dell PowerEdge 6300 with 2 dual core Xeon processors. According to

the Device Manager, I have 8 processors. I can just remove 6 of them or is

there a better way to get Windows to detect the correct number of

processors?

 

Thanks,

Re: Too many processors

 

It's not wrong - it believe Windows will show 8 because you have 2 dual-core

processors, most likely "4-way", which will come up as 8 in device manager.

I can't say I know exactly how to explain it though because I don't know

the ins and outs of processor technology. I have an HP Proliant DL580, with

2 dual-core processors, and it comes up as 8 as well because it's "4-way".

 

I would not remove the processors if I were you. I'm sure someone else can

better explain it...

Thanks for the explanation.

 

I'll leave it alone.

Re: Too many processors

 

Just wanted to add: I suppose it could be wrong, but the fact is I purchased

3 identical servers with 2 physical processors installed (dual-core Xeon)

and each server comes up with having 8 processors in device manager. So

however Windows is coming with 8 I'm not sure, but I guess I just wouldn't

go about deleting the processors from device manager. Windows is obviously

picking up more than the actual physical # of processors installed per socket

and incorporating the dual technology, etc, and finding there is more than

2. I don't really know what 4-way means other than it was listed as a spec

next to "Server Scalability" for my server. My server can have up to 4 physical

processors installed, and then I bet Windows will then see 16 processors

in device manager if i were t install 4 dual processors total. I also have

a couple of other servers that show more than the actual physical #, but

those are also dual-core processors, etc.

 

If you are concerned about licensing, such as for SQL, it does go by the

number of sockets. So, in my case, even though it shows 8 processors, I

only have 2 sockets with 2 processors installed (1proc/socket), so I would

only need 2 SQL processor licenses. I have a good article on that somewhere...

Re: Too many processors

 

Just a thought: I believe device manager indicates twice the number due to

the hyper-threading of the processor. Which enables simultaneous

multi-threading of the computations. I have noticed the similar indications

of XP machines.

Dual Core processors come in two types, with and without hyper

threading, so each CPU has two cores, and each core could also be hyper

threading - so, a single Dual Core CPU could show as 4 CPU.

 

There are also Quad Core CPU's and they show as 4 CPU's. In my

experience I've not personally seen any Quad Core CPU's that also are

hyper threaded.

 

When you have 8 CPU's you really need to pay attention to SQL Queries

because of parallelism and blocking.

Re: Too many processors

 

2 hyperthreaders per core (?)

2 cores per processor

2 processors on mobo

 

2 x 2 x 2 = 8
