Processor fsb
Last response: in Systems
hi..
my pc specs is this..
Intel® Desktop Board D945GCCR supports a single Intel processor in an LGA775 socket.
Intel® Celeron® Dual-Core Processor E1200 1.60 GHz 512 KB 800fsb is my processor
System Memory Features
The board has two DIMM sockets and support the following memory features:
1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
2 GB maximum total system memory
Minimum total system memory: 128 MB
Non-ECC DIMMs
Serial Presence Detect
DDR2 533 or DDR2 400 MHz SDRAM DIMMs
my question is.. is't ok if i use ddr2 1gig 667mhz on my system since the supported only is 533mhz and 400mhz... but my processor fsb is 800mhz?

Definition time:
E1200 frontside bus frequency is 200 MHz.
Using DDR2 RAM, you need a memory clock frequency of only 400 MHz. (FSB X 2 - DDR2 , remember?). That means that if you do not overclock, you only need DDR2-400 RAM to keep the memory in step with the CPU.
The FSB clock is 800 MHz (200 MHz FSB freq X 4). The bus transfers 4 chunks of data (it's called "quad pumped") each bus cycle.
I would put in DDR2-800 memory. It would give you some overclock headroom. It would also give the opportunity to upgrade to a faster chip without the memory limiting performance.

hi...
can i mix single sided ram and double sided ram? they are same in. voltage, size, brand, timing... running in 533mhz
