Specs: Windows XP, phenom II X6/4GB DDR2
Hello,

I recently bought the AMD Phenom II X6 1055t CPU. I installed it in my ASUS M3A78-EM motherboard. I have 4GB DDR2 ram at 335mhz frequency. My motherboard should be compatible as it this CPU is in the support list and I downloaded the right BIOS version (2401).
I run windows xp (32-bit) home edition. FSB:DRAM is 3:5.

When I ran CPU-Z, I noticed that only 1 core was active. My computer didnt get any faster too, I still cant play black ops for example although I easily meet the system requirements.

How can this happen? Is my computer power supply too low?

that because of turbo core technology. When the system is idle 5 cores are disabled and 1 core remain active. Why are u still using xp 32bit? Win xp doesn't take advantage of multi-core cpu, u should be using windows 7 64bit.
nowdays amd doesn't use fsb in their cpu's, they use hypertransport. Do u have a v-card? If yes name it.

Thanks :)

But will windows xp use the multi cores when I play a game that supports those cores?

And I thought CPU-Z would show all cores, even when not active...?

The ratio is meaningless. AMD systems haven't had a FSB in over 5 yrs. You should be running the RAM as fast as possible. It looks like you only have DDR2-667?

I only have DDR2 333... Does this make me unable to use all 6 cores?

Can and should I make it run faster?

EDIT:

According to the ASUS website my motherboard doesnt support DDR2 333. But I have been using this memory for over 2 years now.

Can you please use HWINFO32 and see what that lists for CPU Cores ?

iam sorry, i didn't saw the link. Hd 3800 series(3850, 3870 or 3870 x2)? Use gpu-z.
U should be running atleast ddr2 1066. Can u see six graphs in task manager? Is that a latest version of cpuz? Try to convert a video or a movie and open cpuz to check how many cores are active.

I see only one graph in task manager, but when I open device manager I can find 6 listings of my 1055t. I will try converting a video/movie.

Im using an HD3850 series

EDIT:

I used sony vegas pro 9.0 to render a video, but according to cpuz I still only used 1 core and my CPU usage % in task manager was 99.

I used HWINFO32 and took this screenshot:

It says 6 cores.

If it ain't broke then nothing to fix, you have six cores...

everything is ok. Do u get low fps when playing cod black ops? If yes which resolution? Are u using eye candy? Hd 3850 isn't good for modern games.

It's not broke, the problem is that when I use programs that require a lot of CPU speed, my cpu won't use 6 cores, it will only use 1.

I can't even play black ops, my CPU usage hits 99% and the game crashes on startup. I just want to be able to use all of my six cores

Going to sleep now; Looking forward to more replies :)!

Just because you have a 6 core CPU doesn't mean your system will run faster than if you had a dual core CPU. Your system's not going to make use of all 6 cores until programs are optimized for using that many. Currenty there's very few programs that can make use 4 cores, let alone 6.

Which CPU did you upgrade from? According to Tom's Hardware Hierarchy chart, all of the following CPUs have similar performance:

Phenom II X6 1055T
Phenom II X4 945, 940, 920, 910, 910e, 810
Phenom II X3 720 Black Edition
Athlon II X4 645, 640, 635, 630
Athlon II X3 450, 445, 440, 435

Also, the 1055T is a 125W CPU, so that means it needs a good power supply & has the potential to run hot. Have you checked your CPU temp? If your press Ctrl+Alt+Del, then click on the Performance tab, how many cores are shown? Do you have Asus PC probe installed?

Temperature is OK. The key part is that my computer doesnt use all cores.

For example, when I open msconfig, go to boot -> advanced options, I can only select 1 processor. But I have the Phenom X6.. How on earth is this possible?

When I open task manager, only 1 CPU is shown.

I upgraded from an AMD Athlon 64 X2 5600+

"Temperature is OK"

I guess it was too much trouble to list the temp? Let me try on mine - click Asus Probe icon, wait a few seconds, CPU temp = 35C. Yep, difficult.

Try this: http://incore.net/winxp-multicpu/

How is it possible that your CPU is only 19C? Unless you have some sort of extreme cooling setup or your average room temp is something like 10C (50F), there's no way those numbers are correct. Try a different hardware monitoring program or check the temp reading in the BIOS.

I checked the BIOS, and there it says the CPU temperature is 36C.

Dear Rieno,

I have the same problem after upgraded my CPU from X2 cores to X6 core.

The solution is listed below:

Step 1: goto msconfig (Run >>> msconfig)
Step 2: Boot >>> Advanced Options
Step 3: Unclick Number of processors
Step 4: Reboot

The solution was posted a few comments back. You have to upgrade to either XP 64 bit or windows 7 64bit to take advantage of the 6 cores. However as stated by others that does not mean that Black Ops will run faster with 6 cores recoginized. First off your memory is slower than recommended by Asus and you don't mention as to how much memory you have but you should run at least 4 gig which again would only be recoginized by a 64bit version of windows otherwise it will only recoginize 3 gig. I had your motherboard with 4 gig of memory, and a quad core 2.8 AMD and 2- amd 4870 video cards in crossfire. Black ops lagged most of the time and I was very unhappy even though all other games worked great. I then upgraded to a 6 core 1055T, 8 gigs of ram, same video cards and a new M4289gtd pro/usb3 and Black Ops fly's. Even though I upgrade 3 components I believe the mother board you have was the botttleneck. However before you go out and purchase a new motherboard, I would change from 32 bit to 64 and upgrade you memory. Hope this helps.
