533 or 400?

[abhi_10_20]

i hav a hp pavilion m7260in pc....
it says it has a 533MHz FSB....bu i hav a 400Mhz(Edited) 256mb ddr2 ram....

can i use a 533Mhz 1gb ram module on my pc?

if ur PC is this
*h10025.www1.hp.com/ewfrf/wc/generi...9246&cc=in&dlc=en&lc=en&jumpid=reg_R1002_INEN

than u can

 

[abhi_10_20]

thanks...
but it says "speed supported is PC2-3200 MB/sec"....
if it is pc2-3200, the it is 400MHz....

so is it speed of FSB wich matters for the type of ram(400/533)?

u cannot use 533Mhz RAM coz its DDR2 and your system has DDR1 slot

 

[abhi_10_20]

hey, i hav 400Mhz DDR2 RAM........

 

[kooabs03]

which mobo do you have? i mean chipset. also 400MHz is a DDR1 RAM. its a 184 pin RAM. DDR2 is 240 pin RAM.

hey, i hav 400Mhz DDR2 RAM........

DDR2 speeds start from 533Mhz... Yours is surely a DDR variety...

DDR2 speeds start from 533Mhz... Yours is surely a DDR variety...

There is 400 MHz and 433 MHz varient of DDR-II refer here *en.wikipedia.org/wiki/DDR2_SDRAM

also refer to the product link *h10025.www1.hp.com/ewfrf/wc/generi...9246&cc=in&dlc=en&lc=en&jumpid=reg_R1002_INEN says, 240 pin DDR-II Connecter with 915P chipset, so should support 533 MHz 1GB DDR-II

thanks....
see my specs:

Memory Installed 256 MB (1 x 256)
Maximum allowed 4 GB* (4 x 1 GB) requires the replacement of installed 256 MB DIMM

Speed supported PC2-3200 MB/sec
Type 240 pin, DDR2 SDRAM
DIMM slots Four
Open DIMM slots Three

whats FSB got to do with RAM speed support?


Intel® 915P Chipset Features
Dual-channel DDR2 or DDR
Flexible memory support, for dual-channel DDR2 533/DDR2 400 or DDR400/DDR333 memory, in configurations of up to 4 GB RAM.

make sure your m/b has DDR2 support.

download CPU-Z & check.

thanks s18 ....

but FSB does matter.....
if u r havin a 400MHz FSB and if u run a 533 mhz ram module, i think it wont work.... 'front side bus' ....this is used for all kinds of data transfers on ur comp...be it with cpu,memory,hard disk,etc.....

There is a cacth here, see if you buy a 800 MHz RAM module, that will be able to oparate uder 533 MHz or 667 MHz...

but the problem is none of the present DDR-II Supports that 400 MHz RAM...

very very few modules of 400 MHz was even pruduced, better option is just by one Higher 533/667 MHz RAM module...

it does work, it wont work on its max. speed, but it'll work, coz i'm running DDR2 800MHZ RAM @ 533MHz with P4 3.06GHz (533MHz FSB, same as urs).

i cant run it above this speed (533), i'll be getting C2D soon, so then only i'll be be able to run the modules at 800MHz & OC them

Hey u missed my post

2days DDR-II supports 533 / 667 / 800, but problem is they are not designed to go bellow it, and if even u force them to go bellow that, and run at 400 MHz stability issue will come up....

 

[s18000rpm]

no i didnt miss your post

it seems his m/b supports 533MHz speed (read my post #11).

abhi, read the PC manual or d/l "Lavalys EVEREST" & confirm whether your m/b supports 533Mhz (probably it shud).

 

[Choto Cheeta]

^^^

It does support 533 MHz but point I am concern is as he wants to run the default suplied 400 MHz RAM along side of the 533 MHz ram !!!

 

[abhi_10_20]

no no no......
i wanna remove the 400 mhz one completely.....

see, if i get another 400 mhz 1 gb ram , it wd cost me more...
as the vendor said the 400 mhz one is out of date and hasnt gud supply....

hence i thought to get a cheaper 533mhz one and use it only..

 

[Choto Cheeta]

^^^^

As per as ur PC product url posted above... u can use DDR-II 533 MHz RAM for sure with out any problem

thanks....
