View 7 Replies View RelatedUpgrade From Dual Core To Quad Core?
Nov 9, 2010QX9650, 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.

Nov 20, 2012I am building a new computer and I want to go with a dual screen setup. I was wondering if I should go with a GTX 670 2GB GPU or two Sapphire Radeon 7870s. If not specifically these cards, let me know what you think. Is it better to have a single GPU with dual DVI output or two slightly cheaper GPUs using crossfire?
View 5 Replies View RelatedDual Core But Windows 7 Only See 1 Core
Jul 8, 2011I 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.
AMD Dual Core Processor Driver
Mar 3, 2009I 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?

Jan 18, 2011I 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.

Feb 19, 2012I've made a clean install of Windows 7 Ultimate a few days ago and I started to encounter the following problem after 30-60 minutes. It usually happens when I'm running a computer game (any game), I experience a sudden fps drop, even though before that, on maximum quality the game was running perfectly, becomes unenjoyable, quit the game. The CPU meter gadget shows 100%, and even after I close everything, browser, windows explorer, the best I get at idle is 70-80% and if I try to open anything at all, it becomes stuck at 100% again.
So I open task manager and go processes, put them in a descending order of processor usage, and see that they nowhere near add up to 100%, even though at the bottom the task manager says CPU usage is at 100%. Physical memory is usually around 20-60%, no problems with that. If I go to Performance tab, and click on resource monitor, I experience the same thing: the actual usage is nowhere near 100%, I can't see any processes that would explain for the performance drop, in fact the highest demanding process is the resource monitor itself. The problem persists until I restart the computer, shutting down takes much longer now.
It's a HP Compaq 8510w laptop with Windows 7 Ultimate x64 Build 7600
Intel Core 2 Duo T7500 (2.2 GHZ)
Hewlett-Packard 30C5 (Intel PM965 (Cresline-PM) + ICH8M-E)
4GB memory
nVidia Quadro FX 570M [HP]
Intel 82801HB ICH8 - High Definition Audio [B1]
I've tried several suggestions:
Disabling HDAC in Device Manager (High Definition Audio Controller)
Disabling Audio Enhancements in Sound>Speaker Properties
Installing the very newest drivers, including chipset drivers
Running programs in XP compatibility mode
Disabling the gadgets
I've no reason to think I've been infected by malicious software, I can't find any suspicious processes running.
