SDRAM and DDRAM

Sephi · July 7th, 2003, 19:31

i know DDRAM is twice as fast as sdram

but what would be better ?

512 sdram or 256 ddram ?

Unicron · July 7th, 2003, 19:49

256 ddr

Edit: Err, IMHO it may depend on what your doing...if you are doing LARGE image and 3d work you may need quantity vs. quality but if your just playing games 'n stuff ddr would be better

Depends on your memory usage but I would go with the 512 MB SDRAM. Playing the latest games tends to strain your memory resources quite a bit so you need every megabyte you can get. DDR SDRAM is about 15-25% faster than SDRAM but with the amount of thrashing that would occur when running multiple programs or big games it isn't worth it in my opinion.

From the speed and RAM amount, DDR surely better. I, however will choose 256MB DDR than 512MB if I use Win98, if you're using XP that need more RAM amount than speed, 512MB SDRAM would be your match.

ha so my 768 sdram is way better than 256 ddram

bahamut_2006 · July 7th, 2003, 20:34

mainly depends on your processor. if you have a p4, go for the ddr, as it can hog up all that sdram easily, if you have an amd proc, it'll handle sdram far better and go for it instead.

**fivefeet8** · July 7th, 2003, 20:53

Well, either of those decisions would bottleneck you in some way or another. Having 512 megs of sdr ram will allow you to run more programs at the same time, but they will load and run slower. Plus the limited bandwidth of sdr ram will bottleneck your FSB if you have an Athlon or P4.

Having 256 megs of DDR is a better choice IMO. You won't be able to run a lot of programs at once, but it won't bottleneck your FSB if your DDR is running syncronously with your FSB. Of course you'll want more DDr ram if your going to run memory intensive games. But if you ran those games on 512 megs of SDR, they'd still be slow because of the slow sdr ram.

I think it's better to get ddr ram now rather then later. Your gonna upgrade memory again.

Well, bandwidth is important, but games also need room to stretch. A game like UT 2003 will take up over 100 MB of RAM off the bat and can nearly reach 200 MB on a large map with lots of players. Upcoming games like Doom 3 and Half-Life 2 will also be equally, if not more demanding. A lot of people also use P2P software like Kazaa and eDonkey as well as ICQ, MSN, anti-virus programs (among others) in the background, which also take up a significant amount of RAM and of coruse we shouldn't forget the OS itself (Windows XP will take up around 100 MB). If there's not enough physical RAM Windows will depend on virtual RAM (page file), at which point thrashing can occur, which can have a huge impact on game performance. It'll also increase loading time significantly and will make it difficult to switch tasks. IMO having more memory would be better. In my estimation 512 MB should be the minimum for any PC power user, especially a hardcore gamer. For large image editing and 3D apps I would recommend 1 Ghz or more.

But if you ran those games on 512 megs of SDR, they'd still be slow because of the slow sdr ram.

SDRAM isn't as slow as you think. ChrisRay reported only about a 20% improvement when he went from SDR to DDR. Benchmarks with an Athlon XP with SDR and DDR also show this. Of coruse with a P4 the difference is quite big, but 256 MB would still be a major bottleneck for most people.

hmm i got P4 but my pc can onyl use sdram or else i would of bought 512 ddram instead of sdram

**n_w95482** · July 7th, 2003, 22:16

I was wondering should I get 1 gb of ram or 512 mb ram for my next comp? I currently have it priced for 1 gb but I'm not sure if i should have/need that much.

what are you going to do with it? Whats the price difference in this case between the 512 and 1g?

20 % is quite a noticeable difference. But when it's concerning load times in games and especial arcade emus, DDR ram makes a lot more of a difference. Loading a 80 mbyte rom in mame takes quite a bit longer with my old Sdr PC150 ram than it does now with my PC3200 DDr ram. Well Over a 50% improvement I'd say. So it basically depends on what your gonna use it for. I'm the type of person that likes my system running at optimal with every application. So I turn off almost everything that's not needed when I run games. With 512 megs of sdr ram, your stuck with a 20% deficit and practically no way around it.

RDRAM ? We're talking about SDR and DDR here. RDRAM, It's fast on the FSB, but its 16bit surely bottleneck.

Well, I've see ppl in this forum [including me] wanted that hard to get 1GB or even 1.5-3GB of RAM for image editing. Working on hugh resolution grater than 1200x1200px will make me painfully to death without that RAM.

IIRC RDRam has a lightning fastfrequency, but has and extremely high CAS latency next to SDRam

go for ddr, sdram are old. In with the new out with the old, you'll have to go drr soon anyway so why not invest in a better hardware (ddr are cheaper than sdram)

**Dark Watcher** · July 8th, 2003, 02:02

erm...we are somewhat confused...
As the hardware gurus mentioned..the processor is the determining factor. Generally motherboards that utilized higher speed processors will also require faster memory...Unless we are wrong (gurus?)...If you have a motherboard that originally used SDRam, you cannot use a higher end memory type because the design of the board is not capable of using it. ..If your mobo is newer with newer processors it will generally require higher end memory (DDR / RDR)..and would be incompatible with slower legacy PC100 / 133 memory types (obviously because of bottleneck)

Isn't DDR RAM cheaper than SDRAM now? For what I see that's what it is.
