ram speed determination

[tech_lover]

Friends,

Please help me determine my exisitng RAM speed and whether DDR 333MHz will work on my moboard or I have to get DDR266

General Information :
DIMM 1 (RAS 0, RAS 1) : 256 (Single Bank) - DIMM, SDRAM
DIMM 2 : Empty

Memory Controller Information :
Memory Controller : ECC, DIMM, SDRAM
Max. Module Size : 1024 MB
Max. Memory Size : 2048 MB
Supported Speed : 70ns, 60ns, 50ns

Chipset Information :
Type : DDR-SDRAM PC2200
Frequency : 135 MHz
FSB/RAM Multiplier : 3/4x
Channels : Single
Shared Memory (video) : Yes

Information SPD EEPROM (DIMM 1) :
Type : DDR-SDRAM PC2700 (166 MHz)
Size : 256 MB (1 rows, 4 banks)
Width : 64-bit

Supported Frequencies : 133 MHz, 166 MHz

CAS Latency (tCL) : 2 clocks @133 MHz, 2.5 clocks @166 MHz
RAS to CAS (tRCD) : 3 clocks @133 MHz, 3 clocks @166 MHz
RAS Precharge (tRP) : 3 clocks @133 MHz, 3 clocks @166 MHz
Cycle Time (tRAS) : 6 clocks @133 MHz, 7 clocks @166 MHz

the motherbo manual just says pc2100/1600 non ecc ddr sdram.

Thanks

PS how do i give points to accepted answers?

no dear 333 mhz will not work on ur mobo until ur mobo supports it if u have more tan 1 stick it should be of same speed unless u will get into some parity errors u can check on ur manual that what is the spped suportd by ur mobo on manufacturesrs website by selecting ur model no

dont think u can use DDR 333mhz !!!

Friends,

Chipset Information :

FSB/RAM Multiplier : 3/4x

The current RAM chip u r using is DDR333 but ur board supports only DDR266 so it is being used at an underclocked speed.

@dIgItaL_BrAt buddy its written Supported Frequencies : 133 MHz, 166 MHz that means his mobo do support 333MHz ram.

 

[dIgItaL_BrAt]

DDR means Double data Rate so the effective frequencies that the RAm can run at are 133x2=266 Mhz and 166x2=333 Mhz.

If u cannect a higher frequency RAM chip to a board supporting a lower frequency,the chip will run,but at the lower frequency.

thanks friends, problem solved

 

[dIgItaL_BrAt]

no problem,dude!

How do I determine existing RAM speed

Hi,

I have an assembled computer (so I literally know nothing about its innards apart from the fatc that it has a 845 mobo and a P4 1.7 Ghz proc). It has 2X256 MB of RAM. I was thinking of upgrading to a new mobo and processor and would probably like to put in more RAM if possible.

1. How do I determine the speed of my existing RAM to ensure compatibility with the new modules?
2. Can I actually put in 1024 as 2X256 and 1X512?

Thanks for the help.

hi use a utility called cpu Z...it'll give u details of ur RAM so tht u can beware of compatibility issues when u upgrade

secondly, if u hv three DIMM slots, nothing's gonna stop u from putting in 1 gb as 2 x 256 and 1 x 512.....but some mobo's hv only two dimm slots.


cheers

thanks a ton for the help
