DDR Ram is real low in price. Got to...

[Vortex]

Thinking about it. $60 bux for 128 stick.
And thats PC2100. What are the bus speeds tho? I know the P4 has a bus of 400 so I don't need some thing that is a buss of 300.

Any one have it? My next system is going to be killer.

Just wanted to talk-_-

Well I am sooo sorry none of you want to talk :(

The new ASUS boards for the AMD processors run a 266 mhz FSB, and support DDR ram. I was thinking about snaggin one of those boards, 256 mgs of DDR, and a 1.3 ghz tibrd. BEAUTIFUL!

Yep. I heat that Kermit. Getting a T-Bird with DDR mobo and RAM is quite beautiful and won't give you as many issues as a P4 with RAMBUS either. There's my observation. Out!

I have a P4, what are the "ISSUES" you are talking about. ´Cause it hasn´t given me ANY issues. And I dont mean to start a flame war, but I would really like to know the issues that you are referring to.

I have the feeling you have NO-CLUE what you are talking about.

What is the issue with Rambus, it IS faster than DDR memory. Is it about price? Then that´s not an ongoing issue with the P4. However in your thread you post ISSUES, (plural) and I have no idea what other ones you are referring to.

RDRAM has significantly higher latency than DDR-SDRAM, is plagued with heat issues, and substantially raises motherboard production costs.

It is expensive and designed by a company with ethics that would make Satan himself blush. Indeed, the rest of the corporate world, including Intel, have all condemend Rambus' strategies, marketting, and general lies.

Facts are that because of latency issues and the serial design of Rambus, the more RDRAM you add to a system, the more latency, hence the slower it goes. Latency is extremely important to benchmarks. I have posted several documents, studies, and benchmarks making my point in older threads.

As new P4 chipsets will be entering the market RSN which support DDR-SDRAM, and the fact that AMD is supporting DDR-SDRAM, and the fact that video card manufacturers favor DDR-SDRAM, RDRAM will have only a slight market share in the coming years.

That said the P4 is a good chip, but I have issues purchasing a motherboard CPU combo that requires me to purchase a new case w/ power supply, that will only be around for a short period of time(P4 redesign), and that only supports an expensive form of RAM, plaugued with issues.

When a DDR-SDRAM P4 comes out, with some upgradability life in it, I might purchase it. Until then, I'm steering clear.

Not really. It gets better overall throughput due to the dual channel architecture of the i850 chipset. The latency still sucks, and that is a bigger issue than raw bandwidth in most apps. So, b/c of high latency, one could just as easily say rambus is slower than DDR.

One quick question...I am real sorry to brake up your way OT story that you people have going in a TOPIC that was about DDR.

What is the buss on DDR PC2100? If I have a p4 400fsb I want DDR to be close to that. Is it above 300? I heard it is only 266fsb or something like that.

Thanks

Last week Intel struck the Brookdale chipset for the P4 which will support sdram

Vortex..ddr 2100 is designed for 266 fsb..use this link and email the folks at the bottom of the page and they can answer more precise memory questions

PC2100 is 133 mhz DDR, or effectively 266 mhz... (well it'd be more accurate to call it 133 mhz with a 128 bit data bus, but that's more or less semantics) and the memory bus on the P4 is not 400 mhz (nor is it 800 mhz... it has a lot of ppl confused b/c they call it PC800... the 800 refers to 800 megabits/sec, not 800 mhz). The FSB speed (NOT the same thing as the memory bus... this is the bus between the CPU and the mobo chipset.. the memory bus is between the mobo chipset and the ram). The FSB on the P4's is 100 mhz, QDR... so effectively 400 mhz.

In the end, don't pay attention to all the various numbers intel and AMD throw around.... pay attention to real-world performance in applications you care about, and base your purchase decisions off of that.

i wish i had a mobo which supports ddr.

i guess gaming would be 10% faster.
