Crucial DDR2 PC2-5300 (DDR2-667): Performance

Examining the specifications for Crucial Technology's Ballistix DDR2 PC2-5300 2GB memory pair, we see that the memory timings specify lower latency than the higher speed DDR2-800 parts. They are specified to operate at CL-TRCD-TRP-TRAS timings of 3-3-3-12 at 2.2 volts. Here is a screen capture of the timings from CPU-Z:

Stability testing was again accessed through the use of SuperPi as one tool. You'll note that at a front side bus speed of 320 MHz, these modules were able to maintain timings of 3-3-3-8 and complete a 32M run of SuperPi with no issues whatsoever.

By slightly relaxing the timings to 4-4-4-8, performance is shown below of buffered bandwidth from SiSoft Sandra 2005 Professional, of nearly 8Mb/s.

This memory and the PC2-6400 both exhibited very stable conditions under stress and at higher clock speeds.

    Not to take anything away from Crucial or OCZ but DDR2~800 @ 4-4-4-12 has been on the market since last year!!!
    Like the article said "Other competing manufacturers such as Corsair and OCZ Technology will be able to source the same IC's......". This isnt just Corsair and OCZ, there are others. Mind you these US memory companies get their work done a lot by Taiwan manufacturers. How about Geil and PQI?? PQI have TurboMemory DDR2~900 @ 4-4-4-12 and a DDR2-1000 @ 5-5-5-15 and both are 1Gb sticks.
    What makes these Crucial sticks special?? Nothing apparently according to the benchmarks. It is nothing more than a publicity advertisement for them......New DDR2 Standard?? I think not!!!!
    Unless you have a rare batch of TCCD equivalent in DDR2 form, the playing field seems pretty even between memory manufacturers to me at the moment.

    Ah winbond megachips, where have you gone to??

    slightly confused because i don't think i ever see the pc2-6400 running at 400mhz? just give me a chart with the max speed with varying timings and i'll be happy. if not, i'll get some myself and do it :p

    No, I'm with you Zebo. I can't wait for DDR2 on AMD's AM2. I'll be getting one of those 35w X2 3800+ CPUs and some phase change ;)
  • BrownTown - Tuesday, February 21, 2006 - link

    why the heck would anyone get phase change on a 35W CPU, thats complete freaking overkill. I hope its not because you intend to overclock it becasue then you will be sorely disapointed. How do you think AMD got it down to 35W? they replaced the current highspeed transistors with ones that sacrifice speed for power consumption. OF course with the FX-62 they have to go the other way and therefore get 125W, but great speed. Seeing as that only a 50% clock increase for more then 3x the power consumption. The new low power transistors will be low-voltage, low-power, and low-speed. Sorry, no free lunch, everything comes at a cost, and here its power for speed.

    Haha, lower speed transistors, you think they would honestly engineer two versons? I highly doubt it, I don't know a lot about CPU's but my guess is that these low power chips are got the same way the turions are they are tested and binned for speed and voltage. The ones that work at lower voltages at high speeds become these special low wattage CPUs and the others become regulars. I dont know about overclocking but I would guess they would overclock better too. Just a guess because no one knows yet though.

    its always interesting when people mock you and then follow it by saying "I don't know a lot about CPU's". But, you are right, they will do the same that they did with Turion. And what they did with Turion was to use differnet transistors than they did in the A64... Before making statements its best to confirm with Google, takes 10 seconds and make you not look like an idiot...
  • ozzimark - Tuesday, February 21, 2006 - link

    there are "fast" and "slow" transistors actually.. ;)
  • Zebo - Tuesday, February 21, 2006 - link

    Am I the only pne who can't wait for DDR2 to be supported by AMD on 6/6/6? Rumour has it unofficial DDR2-800 support - combined with A64 superior memcontroller 3-2-2 800 possible? I hope it's tested Wes.
  • Googer - Wednesday, February 22, 2006 - link

    Zebo, I think I am staying away form any RAM that has Satanic Memory Timings.

    As for the Socket AM2 Tomshardware has already benchmarked it.
