i have a 2GB 677mhz DDR2 stick of ram in my laptop

but it is only running at 533mhz

cpu-z says its running at a fsb x 2 ratio so 133 x 2 = 266mhz

so double data rate ram, 266 x 2 = 533mhz

how can i get my laptop to work at the full speed its capable of?

by the way i have a intel celeron 530 processor if that helps.

Thanks.

P.S - My laptop bios doesn't support any ram timing/cpu/fsb speed changing unfortunately :(

The CPU is on a quad pumped 133MHz FSB (ie 533MHz). As the RAM connects via this to the CPU there's no point running the RAM at anything faster than 533MHz.
 
I been having a look around and can't find much info, it may be the case the board can not run any higher speed memory.

hmm i thought that, but this is what the official laptop manual says ...

Supports dual-channel memory,
Supports up to 4 GB of system RAM,
PC2-5300, 667-MHz, DDR2.

the key phrase here is "supports upto" it's not only referring to the amount of RAM but always the type/speed.

If the CPU is locked at 533 then the RAM will be too, if you want to run the RAM faster change CPU (and MBD).
 
i've decided to revive this thread, my other laptop has a core duo t2250 with a FSB of 533mhz and its ram is running at 333.5mhz x 2 = 677mhz!

so whats wrong, its not my mbrd either ... it must be a setting, ive even tried resetting bios to defaults and still nothing :(
 
Now matter what you think, want or do, chances are your bios does not have the option available to adjust the ram manually, very few laptops do, their BIOS tends to be locked down more than a desktop BIOS, so I would stop worrying about it and just use the darn thing :)

also, your other laptop will have a different motherboard and BIOS so you can't compare the two.
 
you could try a motherboard update. new firmware might fix the problem. It all depends on whether or not the memory is recognized as capable of 667.
You cant change it manually.
