SDRAM or DDR Ram ? Dose It Really Make A Differents???

[cnn7]

Hey Guys & Gals i have 600+ Sdram in my system. 1.8GHZ P4 400 fsb. would putting DDR in really make a differents in my system ?

I went around and around on a video card. I had a gf2 mx 64mb and picked up a gf4 ti 128MB ddr. in wolfenstein enemy terriorty I didn't really notice a change or big change. had a little sharper picture.

So now i'm at the ram upgrade point, will it or will it not be worth the 100+ $$$ to change over to the DDR ram

With a Pentium-4, the difference is massive. The P4 isn't very good at masking the speed of the RAM array through the use of its own buffers and caches - much in contrast to the Athlon.

So yes, if your board can do DDR as well, you'll see quite a performance jump.

What Peter said, P4's are memory bandwith hungry as it is, and most CPU's above 1.5Ghz will experience a bottleneck from SDRAM as it is, so yup, its worth it

P4 needs the fastest mem it can get to make up for certain CPU inefficiency's. Been like that since day one. Thats why they went rdram before sdr. SDR was only introduced due to public demand. Intel never aimed P4 for low speed mem. It wasn't designed around that. It was designed for rdram. Since rdram got dropped AGAIN ddr is your best option. Both price and speed wise. DCDDR pc3200 (if mobo supports DC) is better than the older pc800. Has lower cas higher bandwidth and costs less. All around better. It will literally make your cpu faster. Which cant be said for XP's. Cause they don't need that much mem bandwidth. Again-all has to do with how the CPU was designed to run. So yep-what peter said.

My 1.5gig P4 was on pc800 rdram and asus P4T-E mobo. It out benched the P4 1.8gig on sdr. CPU benches I mean. Not just mem. So it occurs sooner than that. Its the design-it shows more in higher mhz for sure. But remember even the 1.2gig (first P4 I believe) was aimed for high bandwidth. Its just that dang long pipeline and its problem with being kept full of data. Hence why they increased the L2 cache with the Northy and it made a big difference. Hence why the extra L2 cache on XP dont. I see a pattern. That is with system mem and L cache I mean.

DDR it is. Now back to Ebay for the shop till I'm broke. Or wifes catches me thanks People again you've shown me the way------>

Good choice on the DDR. I still haven't convinced myself to buy computer components on Ebay. I buy lots of other things there, even sold my old laptop, but lots of scams

I'm very picky on who i buy from. Feedback can have Negs, but I search each neg to see why. If the auction I win has slow shipping I put it down, if i get the item and it's as described. I leave poss. shipping cost are always high trying to get more past Ebay without fees.
Each seller says what ever it takes to get you to buy there items. you have to know what your looking for and go for it only. Don't settle for anything else. Thats why I come here to find info out on items and computer issues. + everything else. even pet stains. OOps time for bowling soon better go have more stuff to check.

bicarbonate of soda powder is excellent for pet stains, especially the smell.

Hope you enjoy your DDR and you shouldda got a Ti4200 and then you would have noticed the diff.

I wouldn't buy ram on Ebay, period. I say that from experience.
Get your ddr from Crucial and get the warranty. After you pay for the ram and shipping on ebay and get- God knows what- you would have spent as much as buying from the manufacturer. I've got close to 512mb faulty ddr from Ebay sitting in the desk here.
Any buyers? No really, not looking to sell it but forewarned is forearmed. Do yourself a favor.

Remember, the only reason P4 systems ever shipped with SDR was because Intel had a contract with RAMBUS that required that they not use any competing high performance memory implementation. So until that ran out at the end of 2001 Intel was limited to RAMBUS or SDRAM only.

That's one reason they pushed the VIA licensing issue so hard in the courts, otherwise VIA would have flooded the market with cheap DDR boards and taken a huge share of the market.
