the massive overclocks achievable with the 1.6A and 1.8A are just getting back the performance you should have had in the first place
Lol ... good one. And pretty accurate

So it's up to you, but before you thrash the price you saw for the RAM, please do a quote online on RB Comp, as it could be your last resort. And also, you're saying you're not buying an AXP so you are staying therefore with your Tbird if you chose to buy the AMD Iwill package? If so you will save money fer sure, but I would recommend going to newer heights, or even waiting for a Tbred and see how it OCs or simply how high it can go.
What is a multi-rate per clock fad?AMD started the multi-rate per clock FAD with the original K7 Athlon!
The type of memory used on your motherboard really has nothing to do with your processor. Your processor has a set amount of bandwidth available for input from memory and caches. This input is transferred over the FSB (Front-Side Bus.) Whether you use SDRAM, DDR-SDRAM, or RDRAM does not matter. All that matters is that data is being fed to the processor's FSB. Thusfar, the only processor with an FSB not equal to the external clock (that is set on the motherboard) is the Pentium 4, which has a quad-pumped FSB.Athlons have always been DDR!
Usually this access is simply to the L1 cache. Occasionally it is to the L2 cache. Rarely, main memory must be accessed. We should note that the L1 cache on the Pentium 4 includes new technology. The instruction opcodes remain in a type of compiled state. This makes the effort of retrieving new instructions during a branch misprediction much more quick. You can in effect skip a few stages of the pipeline this way. I expect all processors to use such technology in the future.The P4's super deep pipeline has to recompute much more frequently than an Athlon due to branch mis-predictions and therefore needs to access main memory more often.
While it does have a shorter pipeline, it also has less cache now. The Northwood Pentium 4 includes 512KB of L2 cache, surpassing that of the Athlon.The Athlon has a shorter pipeline - less recomputes - and deeper cache reserves
This is true of any processor. Increase the clockspeed on a processor by X% and you will increase the amount of memory bandwidth it desires by X%. Note that the percentages do not change.... as the GHz rises, so does the reliance on memory bandwidth.
This is also true of any processor. It is why the Pentium 4 platform does not perform as well with DDR-SDRAM as it does with RDRAM. An RDRAM memory subsystem will deliver up to 100% more memory bandwidth to the processor.If you asynchronously underclock the memory, you are strangling the blood to the brain.

Sorry, I just do not see it. The current form of Athlon is not a better value than the current Pentium 4. Things may change when the 0.13 micron Athlons come out. But until then, this simply is not the case.if you look at benchs, you'd still find it that the AthlonXP would do better in value
Do not go with DDR-SDRAM for a Pentium 4 unless you want to starve it for data. Quality DDR-SDRAM costs more than RDRAM these days, and you get less performance for that higher price.if you have read my link and know that you should go DDR in both systems for a cost-effective P4(SiS645)

So the Athlon's FSB is 64-bits wide and runs dual-pumped off the external clock? That is news to me. Why is it that everyone refers to its FSB as 133MHz then? At any rate, if this is the case then I do apologize.That is misinformation ray, tread lightly.

Performance suffers when using DDR-SDRAM because you begin to starve the processor for data. Whether that data is for an application or for instructions that the processor requires, it is going to stall the processor and hurt performance.If this were true, then the p4 would not lose as much as it does when doing onto a ddr system
Why would the Pentium 4 perform better with DDR SDRAM if instructions were usually found in the L1 and L2 cache? Memory would have no affect on this, except during the rare fetch from main memory. Because these fetches are indeed rare compared to the cache hits, one gains only marginal performance benefits from DDR-SDRAM's latency. More often than not during the execution of an application, the processor is stalled waiting for application data. If your memory bandwidth is being saturated by application data fetches, then any instruction fetch will be delayed further. Ensuring adequate bandwidth to avoid saturation becomes extremely important in maintaining low latency for fetches at these times.the gain from the lower latency of the ddr system(as opposed to the high latency of pc800) would mean that the p4 would perform better with ddram, which is obviously not the case.

Q: Is the AMD Athlon processor compatible with Intel´s Pentium® III motherboards?
A: No. The AMD Athlon processor uses AMD´s Slot A module design, which is mechanically compatible with Slot 1 motherboards but uses a different electrical interface. Because Slot A and Slot 1 infrastructures are not electrically compatible, the AMD Athlon processor cannot work with Slot 1 motherboards. Slot A is designed to connect electrically to a 200MHz system bus based on the Alpha EV6 bus protocol, thus delivering a significant performance advantage over Slot 1 infrastructure.

I will have to disagree here. The best quality RDRAM available right now is Samsung. A 256MB module of Samsung RDRAM will cost you $71 (PriceWatch). A quality piece of PC2100 DDR-SDRAM will cost more than this, and is usually best not bought off PriceWatch.However, quality ddr ram is still less expensive than rdram
I already conceded this one... 😉The athlon cpu communicates with the northbridge...

As far as comparing PC2700 modules, he indicated he wanted to overclock. Eden told him to get a DDR-SDRAM platform. This would require memory that is faster than PC2100. If he wanted to reach the speeds most are getting he will need PC2700 memory. There is no other way to do it.

This is not really very valid. The best RDRAM is not necessarily manufactured by the same company as the best DDR-SDRAM. There are a great many more things to consider other than the core DRAM off which all current memory is based. So far I have not seen anyone recommend Samsung DDR-SDRAM for high quality (CAS 2) operation.Secondly, The only way to negate various factors is to compare from the same brand, that I have done.
Please look up the word 'concede'.What are you saying, the evidence is clear ray.
