Upgrade From Dual Core To Quad Core?
Nov 9, 2010
QX9650, quad core, task manager, cpu-z, cpu-id, shows showing only 2 two cores.I recently upgraded an Intel E8500 to a QX9650 and had the problem of Windows 7 only showing 2 of the 4 cores.It took a few frustrating hours to find the solution, but I got there in the end without the need for a Windows re-install.
1st: You must have Windows 7 Professional. Home Premium does not support more than 2 cores. Upgrade to Pro.
2nd: If Task manager and CPU-Z are only showing 2 cores, you'll be feeling pretty confused, right?
Go to Start-->Run, type MSCONFIG.Under the BOOT tab, click 'Advanced Options'.In the top left corner it says "Number of Processors" (you'll have been here already and it says '2').Uncheck this and do a reboot.This solved my hours of confusion. Now I have 4 cores in Task Manager, CPU-Z and all is well.If all this fails, then get yourself set up for an OS reinstall; that should get you where you want to be.

I'm having an issue with my CPU. It seems that it is only using one of its cores. This issue first became apparent to me when I was trying to run Blacklight Retribution. It popped up a warning message saying that my computer does not meet the minimum requirements of have at least a dual core. And indeed the game was unplayable, with single digit fps constantly. However when i go to the performance tab of my task manager it shows 4 graphs, meaning that 4 cores must be running. Then I go the boot tab of my systems configuration, click on advanced options and underneath the "Number of Processors:" check box (which is unchecked), it shows 1 as the number of processors. My processor is an Intel(R) Xeon(TM) CPU 3.60GHz (4 CPUs), ~3.6GHz.

I'm not overly familiar with low-end hardware (look at my specs ). What was the difference between Intel's Core 2 Duo and their Pentium Dual core? They seemed like identical CPUs to me.

I have a pc that came with XP but is now running windows 7 Home Premium 32 Bit. (SP1 with all updates)
Ever since i upgraded windows has only seen one core even though its a dual core system. The processor is a AMD Athlon 64 Processor 3500+ 2.20Ghz.
I have checked the BIOS and cant find any related settings and when i go to msconfig in the boot menu (advance) Number of processors is unchecked by default and if i check it the drop down only shows one core. The device manager is not showing any driver issues.

Basically, I do a lot of video converting since I'm always sending movies/tv shows to devices like PS3, Playbook, Xbox and some other stuff. Most of the converters I've found support only single core CPU's and take an hour or so to convert, I was wondering if there are any conversion tools that support more than one core and would be much faster than standard converters?

I just received my copy of windows 7 upgrade. I took the advisory test and passed it. I am just wondering if you would recommend me doing any pre upgrade changes before doing the upgrade I am currently running
AMD Athlon 64 X2 Dual Core 3800+
2.00ghz
3.00 Gb Ram
6200 Nvidia Gefource
Windows XP Home Edition
Version 2002 service pack 3
Other than that nothing much to state everything else will be migrated over.

I read the instructions and will attach my dump files and report as a zip file. I build my system myself, but the last few weeks I keep getting BSOD.
AMD quad core
Asus motherboard
8 gb Geil memory
Asus GPU
The dump file shows ntoskrnl is the driver causing the BSOD. Another dump file says ElRawDSK causes BSOD. Both offcourse are drivers.

I recently updated my mobo's bios and with the update I now see this "press F4 to use ACC". I have an AMD Phenom II X4 940 BE CPU. Is there any benefit to using this new function that ASUS is offering with my quad core.

I'm having is that I recently installed Windows 7 Ultimate (from XP Ultimate) and the computer was working really slowly.
First I opened task manager and found only one CPU was being monitored, there was only one window for one CPU, not two windows with only one firing!
This I found strange, checked the WEI and my processor got a 2.3 rating (its a Core 2 Duo @ 1,83Mhz, a T5600), I then downloaded a tone of widgets to check if they could "see" the other core, nothing. I went into msconfig, the no. of processors box is unchecked, if I check it, the drop down menu only gives me the option of picking 1 CPU.
using Vista, but I can't seem to be able to use his fix: [URL] (bottom of page, can't find the HAL detection checkbox)
I am running Windows 7 Ultimate on an HP nx9420 laptop with 3GB of RAM, a new HDD (250GB), the old one just stopped working really, and the Core 2 Duo T5600 @ 1,83Mhz that is running only one core.

So I'm on my computer playing a game and I have a CPU usage gadget by Keat and the gadget is telling me, my Core 2 is at 82% while Core one is at 25%.
aren't they supposed to carry the load equally, Or is that normal? When I have something else up besides the game I'm playing (MineCraft online) it evens out more.
My system specs are Windows vista (but updated to Windows 7 Home premium and completely updated) Pentium dual core cpu t4200 4.00 gb Ram. 64 bit

I just bought a: AMD Athlon X2 2.2 GHz 4200+ Socket 939 89W Dual-Core Processor
and I have spent many hours trying to get 7 to detect that there is two cores in this thing and that it needs to utilize them both. But I'm not really sure if there is a driver out there that I can use... The setup I found would say its not compatible with this OS when I ran it.
Is anyone else having issues with 7 detecting their AMD dual core processors correctly? Are there some compatible drivers that I've missed?

I picked up a couple Dell Optiplex 745's that are almost identical. A friend of mine has the same machine that runs Windows 7 flawlessly. I, however, can only install it and run the OS when disabling one core of my Pentium D 2.8GHz (Presler) CPU. When I go into the BIOS and re-enable the 2nd core the system becomes completely unstable.
Some basics:
x86 (32-bit)- Windows Home Premium retail (Came from Dell with XP)
System close to four years old, with format and clean install of Windows 7. Machine does run OK on Windows XP with both cores enabled. Both machines seem to perform exactly the same so bad CPU or memory seems to be a longshot.

I upgraded from vista to windows 7. Its worked like a charm, but there are one problem.
I have a q6600 cpu(4 cores), and after the upgrade windows see just one core.
(In task manager(One Graph per cpu checked)/Resource Monitor)
In the Device Manager under Processors are listed 4 "Intel(R) Core(TM)2 Quad CPU @ 2.40GHz" device.
I reinstalled the old drivers, removed them but no luck.
Any advice?

my laptop spec are:
Core 2 duo T5800 2GHz
3GB DDR2 RAM 667
ATI HD 3470
Can this handle 64bit? I see some people here have good experiences with 4GB ram, but some recommended 8GB.

My wife is looking to buy A Windows 7 system and she is looking at the above. I can't remember whether regular 32 bit programs will work on a 64 bit cpu. I assume Windows 7 will be 64 bit though.
