My 1st pc is Pentium D 820 which is Dual Core . It has 512 KB DDR Ram (PC3200) & speed of CPU is 200Mhz x 14= 2.8 GHz . When I ran Everest Ultimate Edition on my P.C. , it gives the following information : CPU Physical Info : Package Type = 775 Contact LGA Process Technology = 7M , 90 nm , CMOS , Cu , Low-K Inter-Layer , High-K Gate ,Strained Si Core Voltage = 1.3 V I/O Voltage = 1.3 V Typical Power = 95 W @ 2.8 GHz Maximum Power = 130 W @ 2.8 GHz MotherBoard Info : MotherBoard Name = MSI865GVM3-V ((MS-7101) FSB Properties: Bus Width = 64 bits Real Clock = 200 Mhz (QDR) Effective Clock = 800 Megahertz Bandwidth = 6400 MB/s Memory Bus Properties : Bus Width = 64 bits DRam:FSB Ratio = 1 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 The 2nd P.C. is an AMD Athlon 64 X2 5200+ (Dual Core) . It has 2 GB of DDR2 Memory (PC26400) & speed of CPU is 200Mhz x 13.5 = 2.7 GHz . For the Second P.C. ,Details are as following : CPU PhysicalInfo : Package Type = 940 Pin uOPGA Process Technology = 10Mi , 65 nm CMOS , Cu , DSL SOI Core Voltage = 1.1 - 1.35 V I/O Voltage = 1.2 V - 2.5 V maximum Power = 65 - 76 Watts MotherBoardName = Asus M2N68-AM SE2 FSB Properties: Bus Type = AMD Hammer Real Clock = 200 Mhz Effective Clock = 200 Megahertz HyperTransport Clock = [Trial Version ] Memory Bus Properties : Bus Type = DDR2 SDRam Bus Width = 64 bits DRam:FSB Ratio = CPU/7 Real Clock = 387 Mhz (DDR) Effective Clock = 775 Megahertz Bandwidth = [Trial Version ] MotherBoard Physical Info : CPU Sockets/slots = 1 Socket AM2+ Expansion Slots = [Trial Version ] RAM Slots = 2 DDR2 RAM Integrated Devices = Audio , Video , Lan Form Factor = Micro ATX MotherBoard Chipset = nForce7025-630a MotherBoard Manufacturer = ASUSTek Computer Inc. 1) Are there any Bottlenecks (for speed , performance , etc ) on any of these P.C.s ? If there is any more info you need , I'd be happy to give . 2) What is the maximum physical memory that can be put on each of these p.c.s ? 3) Also , since both CPUs are x86-64 machines but since my windows is 32 bit (Windows XP Professional SP2) , aren't these machines being under-utilized ? (Although I can understand , 64-bit windows isn't very popular since getting drivers for programs can become a problem ) . 4) Upon running CPU-Z , Core Voltage shown on the Intel P.C. is 1.33 Volts as against 1.39 volts for the AMD machine . However RAM Voltage is 2.5 for Intel vs 1.8 for the AMD machine . Which machine must be consuming more power ? 5) Nero System Info says there is AWRDACPI on the machines . If ACPI is installed , why am I not given any option by Windows whereby I can make settings for Windows to automatically shut down the Printer if the Printer or Scanner is idle for say n number of minutes ?
pc 1: no bottleneck 800mhz system bus frequency (6400MB/s) and memory bus frequency 400mhz x2 (if dual channel config) which will be 800mhz so memory bus and system bus are both spot on. pc2: 1000mhz on the system bus and memory bus frequency 800mhz x2 which is 1600mhz (12.8GB/s) so your system bus is the bottleneck. as for maximum memory capacity per dimm on each motherboard is: pc1: 2GB max support ram and 1GB per dimm. non-ecc unbuffered dimms. pc2: 4GB max support and 2GB per dimm. non-ecc unbuffered dimms. 64bit and 32bit OS's pc1: x86 cpu instruction set pc2: x64 cpu instruction set, I would recommened installing 64bit OS on this machine overall better performance, drivers won't be an issue for this motherboard as windows will install generic drivers for cpu, ram, most chipset controllers, opticle drives, hard drives, some onboard nic's and audio and a few intel onboard raid controllers. As for programs you have x86 program files folder and x64 programs folder so you've got the best of both world. As for ACPI is this enabled in the bios? have you checked? also your hardware/devices must be APCI compliant in order to have the option to power off devices.
