Identifying any Bottlenecks in my P.C

February 11, 2010 at 05:09:10
Specs: Windows XP Professional SP2
My pc is Pentium D 820 which is Dual Core . It has 512 MB DDR Ram (PC3200) & speed of CPU is 200x14= 2.8 GHz . When I ran Everest Ultimate Edition on my P.C. , it gives the following information :

FSB Properties:
Bus Width = 64 bits
DRam:FSB Ratio = 1
Real Clock = 200 Mhz (QDR)
Effective Clock = 800 Megahertz
Bandwidth = 6400 MB/s

Memory Bus Properties :
Bus Width = 64 bits
Real Clock = 200 Mhz (DDR)
Effective Clock = 400 Megahertz
Bandwidth = 3200 MB/s

Chipset Bus Properties :
Bus Width = 8 bits
Real Clock = 67 Mhz (QDR)
Effective Clock = 267 Megahertz
Bandwidth = 267 MB/s

Question 1 :
Are there any Bottlenecks on my P.C. ?

Question 2 :
Also , since my P.C. is a x86-64 machine but since my windows is 32 bit , isn't my machine being under-utilized ?( Although I can understand , 64-bit windows isn't very popular since getting drivers for programs can become a problem ).

It would help to know the make/model of the motherboard or at least the chipset the board is based on & also which video card you have. Based on the CPU & RAM, your system is already bottlenecked.

For one thing, the Pentium D is a poorly designed CPU & is already crippled by it's netburst architecture. To help overcome the inefficiency of the CPU, the RAM's "real clock" speed should be be higher than the CPU's "real clock" speed. Right now, both are running at 200MHz, so it's a 1:1 ratio. For optimal performance, the ratio should be 3:4 with the CPU at 200MHz & RAM at 266MHz. It's not gonna happen with that setup though.

You also don't have enough RAM. 512MB isn't enough these days. You should have at least twice that much...more would be even better. And you should have a discrete video card, not onboard graphics that rely on the system RAM.

As for 32-bit vs 64-bit...XP x64 didn't have the driver support & Vista was never widely accepted in either the 32-bit or 64-bit form. Windows 7 64-bit is very popular though.

Sorry , jam , I think made slight mistake in writing the specifications . Have corrected them in my original post . Can you please just go through it again (Mainly , I had written the chipset entries wrong ) & tell me would you still stick by the same advise .

The motherboard is MSI 865GVM3-V (MS-7101) from Micro Star International .
Chipset Details are as follows :

North Bridge Properties
North Bridge - Intel Morgan Hill i 865GV
Supported FSB Speeds - FSB 400 , FSB 533 , FSB 800
Supported Memory Types - DDR266 , DDR333 , DDR 400
Maximum Memory Amount - 4 GB
Revision Stepping - 02/A2
Package type - 932 pin FC - BGA
Package Size - 3.75 x 3.75
Core Voltage - 1.5 V
In Order Queue Depth - 12

Memory Controller -
Type - Dual Channel (128 Bit)
Active Mode - Single Channel (64 Bit)
PAT - Disabled

Is this the additional detail you required ? What does all this mean ? I have not installed any video card .
