Corsair to Continue Receiving Samsung TCCD Memory 56

Posted by CowboyNeal from the not-done-yet dept.
Doggie Fizzle writes "Bigbruin.com has a review of some Corsair XMS TWINX1024-4400C25PT DDR, but info on the future of TCCD may be the most interesting part. TCCD chips are well known for their proven overclocking, but the buzz is that Samsung has stopped making TCCD chips, and that we will no longer see them on the market once the current supply runs out. Not true according to Corsair. According to a source quoted in the review, Corsair will soon be the only source of TCCD chips."

    Personally I don't much like the XMSTWINX1024-4400C25PT. I think it's a jerky name. Still, it could be worse. I once knew an memory stick whose middle name was 2Q4B. Poor sucker!
  • I can't tell the difference between a machine running with this XMS memory and one with normal DDR SDRAM. Sure, I can see the difference in the benchmarks, but real-life speed isn't really a problem. For all intents and purposes, it's the same.

    In addition, it's the limited bus speed of the x86 architecture that is the primary bottleneck these days. Running at only a fraction of the processor speed, memory accesses are slow because the bus can't keep up with the CPU and everything in turn waits for the b
    • Actually, the memory is kinda the bottleneck. Becuase current RAM technologies has a speed which matches the bus, increasing the bus higher it great except for the fact that RAM can't stand going that high. Most new Athlon64 boards with Hypertransport can hit 1.25Ghz bus speed (if you take into account the HT multipliers) but RAM speed dividers have to be used to keep the memory from dying, which as any overclocker knows is more often than not the problem with any overclock.

        Kind of the bottleneck? There is not "kind of" about it. It is one of the bottlenecks. Otherwise, why do we have caches?

        And what does HT link speed have anything to do with memory on Athlon 64? Unless you're running multi-processor Opteron, CPU's memory accesses don't travel through the HT link. Internal path between CPU core(s) and DRAM inside K8 is way faster than any current DRAM technology can use. Not only that, it scales with K8's frequency, unlike HT or DRAM.

        And what does that "hit 1.25GHz" tell you anyway? First of all, HT links are double-pumped, so 1.25GHz at 8-bit link is 2.5GB/s (minus overhead). Same at 16-bit link is 5.0GB/s (minus overhead). Frequency alone doesn't tell you anything. I fear the original poster may have been thinking that since it's 1.25GHz (>>400MHz of DDR400), it's plenty. Yeah right. Dual-channel DDR400 has 128-bit bus width (6.4GB/s), not that this has anything to do with memory bottleneck since CPU/DRAM traffic does not travel on the HT links.

        Who's modding these "Insightful?"
      • Aren't the memory controllers on new AMD processors on-die now anyway? That'd make the bus speed irrelevant to memory performance (according to the hype, anyway).
    • Bus speed is not the limiting factor, especially not with AMD's x86 implementations. Memory *latency* is the biggest problem with high speed memory, and TCCD's are known to clock fairly high while maintaining low latencies.

      I can't tell the difference between a machine running with this XMS memory and one with normal DDR SDRAM.

      And there was me still having difficulty telling the difference between EMS and XMS memory - does anyone else feel that computer technology is leaving them behind?

      I built myself a new PC earlier this year. Half the acronyms had changed since I'd built my previous one... ;-)
    • "Sure, I can see the difference in the benchmarks, but real-life..."

      Real life?
      For many on this site, benchmarks are "real life"
  • How much demand is there actually for these chips? Obviously it's not *that* high as there would be no point in discontinuing them otherwise. Corsair has built themselves a strong reputation for the niche market of overclockers and this will strengthen their position.
    • This just in, spending 200$ per MB for memory to get a 0.01% speed boost has been determined to be not worth it.

      It is cool to have low latency high freq memory but honestly... In the grand scheme of things it doesn't really matter unless you're much faster or much slower.

      A CL from 2.5 to 2 is faster ... but you're not going to really notice it.

      Now say double the bus width or frequency with a CL of 2 ... that would be a nice increase in speed.

      The other problem is these DDR/QDR schemes... if you want say
    • There is actually quite a large demand for these chips among PC builders who know what they can do. The average Joe who walks in and says "I want more memory" isn't going to have a clue, or a care, about these chips. But they do make a distinct difference.

      I recently built myself an Athlon64 (3200+) system and put in a 1GB (2x512MB) set of Corsair "value brand DDR memory (recommended by the motherboard manufacturer, DFI). I had stability problems at stock speeds all around and RMA'd the first pair. When
