Surely they will be using something better than DDR2. or have DDR2 with an obscenely high core speed.

I'm almost certain they either have built in hardware testers, or a 4*62,976 threaded memory tester application that will report the location of a faulty stick.

You mean just like they'll "surely use something better than athlon processors"? :rolleyes: Athlons have the memory controller built into the CPU die itself to reduce latency, so unless the machine was built with older S939 chips (in which case it's using DDR1) it'll be a DDR2 system.

Kind of like finding the handful of failing vacuum tubes in the original ENIAC. Multimeter anyone? -CB ;)

http://www.wired.com/science/discoveries/news/2007/06/sun_supercomputer[^] 62,976 CPU cores, 125 terabytes of memory, 1.7 terabytes of disk space, and 504 teraflops of performance. "In some ways it's like giving us a time machine to look forward five to ten years as to what general purpose machines will look like. The smart developers will take advantage of that (today)." Chris, when can we expect CP on this platform? That should help speed up the responses to all those very urgent, please help me quickly requests ;P
only two letters away from being an asset
I've filled out a Purchase Order, but I'm not getting my hopes up too high.

Yes i know that, it reduces the timing for the data throughput, but what I mean is surely such a large system wish such a price tag will use something similar to DDR3, which to my knowledge is similar to what the old DDR2 cards were, as in being to expensive to be used for system RAM in general consumer machines at present.

Unless they convinced AMD to sell them custom/6-12mo advanced prototype CPUs it can't be using DDR3. Current model athlon/operterons have an integrated DDR2 controller. IT can't talk to DDR1. It can't talk to DDR3. I suspect they're using highend gamer ram with godly clocks and timings but it's still DDR2. They have no choice on the matter since AMD made the ram decision when they manufactured the chips. In any event, current DDR3 isn't actually any faster than DDR2, the clock speed gain is just fast enough to balance the latency penalty, and the highest end DDR2 still has a tiny speed edge. This will change in time since DDR2 speeds have largely hit a wall and DDR3 is only currently available at the low end of the spec at present.
