Hello everyone,

I'am pretty sure i have a 4-core computer, but when i open task manager it shows only 2 graphs...

Processor: AMD Athlon(tm) II X4 620 Processor 2.61GHz

And i thought i read somewhere that the X4 stands for 4-cores.

Picture from my task manager

Am i wrong? or am i overlooking something?

Gratz: FreeFury

Addional information: i use Windows 7 64 bit, and i need more CPu >:) (for PS2, which needs more CPU)

I think its not true quad-core only 2physical and 2logical.

i googled, and it should be a quadcore

Thats the problem. Those companies for cheap models says its quadcore but there are only 2real cores and 2logical

i look on multiple site's and not just their site and most say 4-cores

Actually that's what hyperthreading does.. it's mostly intel tech.

this is what it looks with me... 4 cores.
WHat Windows are you using?

To put it in a nutshell, it creates 2 logical cores, that optimize the time that your processer is actually processing data.

It must be disabled in the BIOS then.

in some cases, the bios disables some cores. mostly to save power,
sometimes that setting screws up and the automation of the powermanagement doesn't work properly anymore.
from my experience that happens a lot with laptops.

you should check your settings, mostly, try disabling energy saving stuff.

There is usually an option like : "No of active cores/threads". There should be something similar in your BIOS settings.

did you activate all your cores?

Go to bios and check if all cores are enabled
to go to bios - > restart your computer and press del ( or something else depends on your motherboard - it shows on bottom of the screen which key you need to hit to enter setup)

i tried the BIOS thing, i pressed F8 (that was the button for me) but i just quitted, i saw a few options on a blue screen and i don't want to just start messing around :s

Perhaps it is possible to unlock it to quad core using bios? Some CPUs come as dual and then unlock further for people who need the extra power.

Can you post a screenshot of CpuZ like this?
If you post also a txt report we can help you more :)

What's your motherboard?
Edit: start > run > msconfig > boot > advanced option. Then check it looks like this and if you could set number of processors = 4.

Go to BIOS and open all the CPU Cores. I had the same issue with my 8 core proccesor, I got to use only two before doing so.

Well I know from my old Asus p5k board that if I dicked around and turned either or memory mapping off or EHCI off the bios load screen would only show 2 cores, though windows would still use and show 4...

Alt you could have your boot settings changed.
run->Msconfig->boot->advanced options-> check if "number of processors" is ticked...

number of processors is ticked and locked to 2 or 1 :s

If i had 2 cores with 3ghz would that make the overall speed 6ghz?

No, it does not add up. Just think of it as 2 cars going at 30mph carrying luggage instead of 1 car.

Yeah. Marketing men love to pull this one, as it makes even the most mediocre of processors sound like an absolute monster.

The number of times I've read adverts in our local newspaper offering me a desktop computer with a "12Ghz Intel chip"...

What? If I buy on of these for my grandma, will I be getting phone calls every evening to remind her how to work the liquid nitrogen cooling, because her PC won't boot up?

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40 GHz, 2403 Mhz, 4 Core(s), 4 Logical Processor(s).
True quad core? Should I be happy with 4 graphs when other people have 8? lol....

Yes, it's a "true" quad core...we could also debate this since Q6600 is made of two E6600 dual cores which are "glued" together. That's also the reason why programs run faster, if they use just core 0 and 2 or 1 and 3 (cores are counted as 0, 1, 2, 3).

lol this thread have so much fails...i would reply each one, but i'm too tired for that. First of all, just Intel CPU's have logical cores; his Athlon is a real 4-core. Second - Athlon II X4 is the model name, the X4 is a part of the CPU name and if windows shows it, it doesn't mean the number of cores (so having an AMD A10 would mean you have 10 cores lol?).

For OP: Post a screen from CPU-Z Mainboard tab, so i can tell you what exactly you need to do in your bios to activate them all.

In this particular line of AMDs CPUs the nomenclature "X4" does refer to the CPU having 4 cores. Same as how X2 for certain AMD's dual cores, X3 for tri-cores. But ofcourse an A10 wouldn't have 10 cores as those are just their APUs, but I guess if someone came along with an untrained eye and made that assumption, they could end up making a bad purchase.
