How do timings translate to real world performance?

I have a basic understanding of what CAS, tRCD, tRP, and tRAS stand for but I don't understand how they translate to real world performance.

For instance, I'm looking at three types of DDR2 800 ram (1GB x2) from OCZ: Gold, another Gold, and Platinum.


Comparison chart for all three:

Lets say I'm playing... FEAR on fairly high settings @ 1024x786 on my hypothetical system (3200+ AM2, 7900GT, ??? memory). How much of an improvement (percent, FPS, adjective description, whatever you want to measure it has) would I see if I used Gold1 vs Gold2 vs Platinum?

And same specs, different purposes: how much of a difference would I notice for video encoding or Photoshopping?

Also, which one of those three would be most overclock friendly?

I'm not looking for real numbers, I just want to know if paying $40 more (after rebates) for Platinum is worth it or if that money would serve me better elsewhere.

  1. Depending on the platforme and wether its AMD/Core 2 your looking art, the numbers will vary.

    If you dont OC, I dont think the slight timming difference will account for much more than 1% in most non-synthetic benchmark. The platinum will certainly bring some more overclocking headroom as you can raise the timmings a little (back to the gold's) and probably reach higher speeds.

    If I were you I'd wait for core 2 duo to come out. this way even if you're going with AMD, you'll likely see better prices. Furthermore, while OCZ is a good brand, you might look into other manufacturers. I find the best way is too wait for comprehensive benchmark testing many diffrent memory.

    Finally if you want to buy it now, I say go witht he cheapest of the three, all good product that will be within 1-2% of each other
  2. All of the benchmarks I've seen have shown ~0-3% differences between even very high and very low latencies.

    On my latest computer, I bumped the timings on my RAM (2gigs Corsair Value Select DDR2) from the stock 4-4-4-12 to 3-3-3-6, and I can't tell the difference in anything (though admittedly the only thing I do which puts major stress on my system is gaming and number crunching, so your mileage may vary). If I up the voltage, I can lower the latencies a lot more, but putting additional stress on the RAM for no noticeable benefit doesn't sound like that great of an idea to me.

    Though for overclocking, yeah, get the low latency stuff.
  3. hey i didnt want to make a new thread just to ask this question so here it is:

    According to the newegg reviewers OCZ Gold2 doesnt work with the ASUS M2N-SLI Deluxe, but the Gold1 does.
    How about the platinum, will it work??
