Some sites will scan your pc and tell you what upgrades you can buy. if you're choosing to buy somewhere else, make sure upi take notes on what it says. What DDR is it? What speed and max upgrade?

If it says your machine only supports 2gig don't buy 4. seems obvious but...

also if running a 32 bit version then windows only recognises max 3.5 gig of ram. get aq 64 bit version if you want max.

which is better ddr or ddr-3

Generally speaking, motherboards are built to support only one type of memory. You cannot mix and match SDRAM, DDR, DDR2, or DDR3 memory on the same motherboard in any system. They will not function and will not even fit in the same sockets.

hey i want to make my own computer. Can anyone help me to get the information for the best performance and brands of computer parts?

i'm a net surfer and game player.

hello sir. I'm just wondering why my ddr ram 512 in ddr slot 1 don't work in ddr slot 2

Thanks to everyone.

 

answer: check with your motherboard.

Q1) How do I check if my computer has DDR or DDR2 without opening my computer's case? i mean from the windows - is there any way ? cause i lost my computer's manual :S

A1)Maybe you can try to check the control board of computer and then you will see all specifications of your computer.

To Anon783: Re: The difference between DDR2 and DDR1. DDR2 is updated products based on DDR1, and DDR2 is faster and saves more power. the thermal diffusivity of DDR2 is better than DDR1 because they use different package technology during production.

Very nicely explained the topic in all respects.

The difference between DDR and DDR2 is the amount of data in bytes that will be transferred per clock cycle of the CPU. Think of the clock cycle as a wave length. DDR sends 1 byte of data per pin which is normally 8 per rise of clock cycle and fall of clock cycle so 16 bytes per clock cycle. DDR2 doubles that and sends 2 bytes of data per pin per rise and fall of clock cycle.

A1) Go to "Run" and type 'dxdiag' it shows your computers specs.

Very well explained and presented. The Author of this article has thought about to put the information in a simple way yet covering the whole topic.

I would rate this an A+.

Hey,

My Toshiba has a Penti4,3.06GHz process,80GB HDD,512MB of DDR SDRAM.

Can someone tell me why the new Logitech web cam keeps freezing my computer?

dude its not that difficult to check whether ur ram is DDR or DDR2. sad news that there is no way to find out without opening ur cabinet through windows. just open ur cabinet screws and flip UP the ram socket's edge triggers. RAM automatically pops out doing so. it is always written on the ram itself about its configuration. Then with a little caution of placing notch of RAM on the slot (see thoroughly the slot for the place for notch). and fix RAM urself as u popped out. trust me its not that techie to do this

have nice computing

CPU-z will give a lot of information about your computers hardware including memory.

I've been using 512 mb for years - And i m a professional gamer, I havnt faced in Ram problem till now, and in fact i play heavy games like WoW and battle of middle earth with msn On and real player Songs on... So to conclude 512 is more than enough for me..|

it would be a great favor if u guys reply

At present my computer has a 128mb ddr ram...can it be replaced by a 1 gb ddr1/ddr2...or does it have to be 1gb ddr?

hi, 2gb enough ram to run all games out today and you would struggle to see the benefits of another 2gb of ram.

I'm gonna build a computer. How much RAM do you need? 2GB seems to be required but will 4GB make any big difference?

hi, well it depends on what you use your computer for, 512gb of ram is enough for quite a lot of games and browsing the internet but if you want to play more graphically demanding games i recommend getting another 512 stick of ram, you don't need 2gb, 1gb will do.

i am a new computer user i don't know how the ddr ram works. is it necessary to have a 2 gb ram? i have 512 mb ddr ram & 80 gb hard drive

hi, my motherboard is running at 140 fsb and my cpu multiplyer is 20 which makes my cpu run at 2.8ghz which im fine with however i have 2 sticks of 512mb pc3200 ram which should run at 400mhz however if my fsb is 140 my ram must only be running at 280mhz, how do i make my ram run at its correct speed as i cannot raise the motherboard fsb anymore as it becomes unstable as it overclocks my cpu to high. also cpu-z tells me that my ram is at 200 mhz so if that is doubled its 400mhz which is what i want but how is it possible if my motherboards fsb is 140 surly my fsb would need to be 200 in order to run my ram at 400mhz.

what is the difference between ddr2 & ddr1?
