Guys, Help me out!!
I am in a confusion here. Lack decision making.
I am buying a memory for my computer, and I gotta decide with in an hour, should i Stick to 512mb SdRam or go for DDR512meg333mhz(pc2700??).
I don't have much time. I have to get it in one hour.
Processor: P4 2.4Ghz
I know I should go for DDR, but some told me SDR is better with 2.4 Ghz... enlighten me in an hour... !!!
Thanks..

DDR is also a type of SDRAM, also knows as SDRAM ll. It is originally designed for laptops coz it consumes much less power. And at the same time, it doubles the memory's data throughput. So if you are using a laptop, you should go for SDRAM ll (DDR-SDRAM), if not, go for whatever the heck is cheaper. I doubt if you can get DIMM(memory slot) type SDRAM ll for your desktop. But I'm lagging behind time you see. I'm sure things have changed.

PP, you mentioned that you are buying memory for your computer. Am I correct in assuming you already have the computer?
If so, the choice is determined by what the motherboard is designed to suppport. DDR or SDRAM ? Check the motherboard documentation for this.
Also, if its DDR, what speed ? PC 2100 or PC 2700. If SDRAM, its PC-133.
Depending on the size of the memory module already onboard, start populating the memory slots from slot 1 using the largest module, then use slot 2 and so on.
Make sure you are properly grounded and are using an anti-static wrist strap. If not, touch the metal of the power supply before touching the components. Also,once grounded this way, dont walk around as static charges build up again if you do.
Good luck.

Anti static wrist strap? haha ..people actually use them? Thought those things are jokes. Good advice Czar...me impressed.

Vivid,
Several years ago I was attending a training program for field servicing of Cisco routers. We were advised to bring along our toolkits as we would need them for the classes. Once all the techies were done with breakfast at the hotel, the lead instructor for the course asked to check every one's toolkits.
Those that had magnetic tools and/or didn't possess a wrist strap were quietly taken aside and asked to leave. They were shocked, but they were firmly sent away. Some had travelled quite a far piece to get there, but no arguments were entertained.
At the end of the day, the man told us why. When any one of us is working on a high end router, we absolutely could not afford to take any chances. Ten thousand volts of static or a carelessly placed magnetic tool can knock out sensitive electronic componets. Kablam, down goes the router.
Now imagine if that is an enterprise class device (and we were workign with such). One might suddenly idle serveral thousand people. Can you calculate the financial cost of that? An who wants to be that feller ?
I might have a million dollar insurance policy against workplace damage that has been caused by me. That bloke had us sweating in the middle of a mighty cold winter.

Hey Czar,
Nice story, thanks for sharing. Now I can see clearly why you would advise one to use anti static band. It is just one of those things everybody knows you should use it, but no one really cares to ever use it. My experience is just the opposite of yours. Years ago, on the first day of my internship with the support team, I had to crack open a box while my mentors monitored me. Before I touched anything in the open box, I paused to look for a wrist strap, like I was trained, while everyone wondered what the heck I was looking for. When I finally found the strap and told them that I was worried about the static, to my dismay, everybody laughed their ass off. I swear, that was the last time I heard of anti static wrist strap.
I agree, there is nothing worse than destroying a chip with static. But still, I refrain from using those damn things, just incase if l become a laughing stock.
Later!

Okay, how about motherboard now!!!
if i have to choose between
1. ECS and supports 533fsb and has 2 PCI slots and 1 AGP slot
or
2. ASUS, and has 3 PCI and 1 agp slot and supports 400Fsb
for 512meg DDR 333 mhz (PC2100).
Too much confusion yaar.
Czar, Actually I am customizing the computer, but I have my limited buget. So the one who is installing it for me, and one of my friends don't agree with each other. I am in the middle yaar. My friend doesn't understand my budget -- and he is pissed coz he thinks I should have bought the parts all by myeslf and build it. The guy who is installing for me is stuck to "my budget". I am here in the middle....!!! Didn't want any hazzels, now I am in the middle of one! :)
Now finally, we have an agreement upon PC2001, and I have to choose the motherboard, and my friend is nowhere in sight. He doesn't pick up the phone, Damn, dude is dead or what!!! Must be busy at work...
So just give me some ideas. Its getting difficult for me, coz I didn't start building it by myself. Had I done that, the situation would be somethign else. Just messed up yaar. Idea dibakshiyos hazur.
Thanks for your response.
PP

If the first motherboard has on board sound and Network interface, 2 pci might be ok if you do not need much scalability. If the motherboard does not have onboard sound and nic, you will need one pci slot for each of the following: modem, Soundcard, network card, scsi card, extra serial/parallel/usb ports, etc etc. More pci slots = more pci cards. Again, it all depends on what you wanna put on your new pc.

jack,
then i should go for 2nd one??

PP, lets have the precise model numbers of both motherboards, if you have it. Then I can study the specs and give you my thoughts on them.
Meanwhile, as Jack said above, the greater number of PCI slots allows upgrading or addition of peripherals, should you so require, in future. In the choices you posted, the downside is the reduced Front Side Bus (FSB) speed. That immediately impacts how much time the CPU spends idling waiting for data.
Despite the super pipelining, out of order execution, speculative branch prediction an all that jazz of CPU design, at some point the slower 400 MHz bus will come into play. Especially if you are doing large database stuff. Hence, if your budget can fit in a m'board that has :
- 533 MHz FSB
- UDMA 133 MHz IDE interface
- Optional : serial ATA interface (for future, not now, as those storage devices must have a premium price on them at this time)
- dont use onboard video, not if you can help it. They often use some crappy SiS or Opti rubbish. Again, budget dependant hai.
When selecting a HD, go for 7200 rpm and UDMA 133 MHz if your budget can bear it. Again, depends on your application. If its large databases you plan to fiddle with, the higher spindle rotation means data gets loaded faster into RAM. Then, due faster FSB, the CPU gets the data quicker and hence optimal performance for a given P4.
Coming back to memory modules, I hope you haven't bought the memory module already and now shopping for the motherboard to stick it into ? That would be putting the cart before the horse. I am sure you ain't done something like now, have you PP ?
Casing is gonna be fire-engine lover-boy red ?? :)
