533 or 400?

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

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

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

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

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

my miskate... Thanks for the info mate...

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?

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.....

@s18000rpm
@abhi_10_20

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....

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).

^^^

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 !!!

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..

^^^^

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

thanks....

intel 915 chipset supporting DDR1 RAM . but it sure supports DDR2

^^^^

What are u talking ??

May be u missed this, *www.thinkdigit.com/forum/showthread.php?t=60930

oops.. my bad! put the DDRs ohter way. but does the board support both DDR1 and DDR2? i had a mercury board which supported both SDRAM and DDR. dunno about this.

There are boards which support both DDR and DDR-II but none of the Intel Original 915 based boards had that option !!!

y dont u guys just read the mobo manual

it clearly says which ram speeds it can support

^^^^

Some time Manual which comes with Branded PC is not quite good to provide such information rather gives graphical images of how to install Drivers and stuff like that

Hi all....

neither 400 nor 533......i got a 667 MHz one....
i am running both the earlier 400MHz one along with the 667MHz one....
everything seems to be fine....

wouldnt there be any problem with wat i am using now???

hello....

hey !!!

u should not run a 533 / 667 MHz ram with another 400 MHz RAM.... they are not (533 or present available 667 MHz 240pin DDR-II) designed to go that low...

run only that 667 MHz RAM...

u may end up with a burned ram module

!!!!

but everything is working fine....
even the vendor told it wouldnt give a problem.....

................
i think the 400Mz one is running in its own clock speed and the other one in its own..... isnt that possible?

No, the 667 MHz is running at Under clocked speed of 400 MHz...

anyway i just suggested you what migh happen, so, its not certain that it will happen, when ur vendor says it will run, then let it be there... run togather.... but if some thing happens, do post back here

thanks......

think its better to remove off the earlier one.... then this one wud run at 533MHz(am i right?) as FSB is 533MHz.....

but its a hard trade off ...i cant see the earlier one simply sitting idle....
