Thread: GA-EP45T-DS3R DDR3-1600 So far so good

    That certainly is amazing settings for DDR3's and decent memory performance. Is this better than what you can achieve at higher DRAM frequencies?

    1121mhz is the highest I can go right now. The next RAM strap on the 333mhz latch will OC my RAM over 1400mhz, which I can't get stable.

    Also, if you have a better DDR3 board, you can use a 525-533 FSB with 2.40b strap, which should give MUCH better read/write/copy than what my board can do.

    On this EP45T-DS3R board, when u get around 500fsb, the whole board switches to a looser frequency latch, and it slows the RAM down a lot. Which is why I'm doing 467x9 instead of 500x8.5

    I have been reading some articles about running the memory frequency slower (which is obviously the work-around for DDR3 and the P45 chipset) and it seems there is an advantage to be had with tighter ram timings (at lower frequency) and higher FSB frequency.

    Looks like Creamsoda has it dialed in perfectly.

    I got my CPU Stable @3.66GHZ @1.3V and was testing my RAM stable so far @1334 7 7 7 20 (FSB 420) and was getting 9107 MB/s read and about the same writing.

    I like Creamsoda's set up and will play around with some timings at lower frequencies.

    Excellent info Creamsoda - thanks so much for your input!

    No problem.

    But to be honest, I don't think the DS3R board is a good board to showcase RAM speed lol, mainly because of the board switching to a slower NB frequency latch at around 500fsb.

    But either way, your Corsair XMS3 is still faster than my RAM. I'm sure you'll get better bandwidth once you manage to get a better OC.

    Yeah,
    The DS3R is a decent board - I was never really looking for major overclocking - just some medium-level OC with stability. With high ambient summer temps I am reluctant to push the NB too far - but your ram timings were a major find - tight timings, lower frequency and lower voltage with equal or greater throughput than higher frequencies - what's not to like.

    Next year will be a i7 with some solid state drives. Mmmmmm solid state drives.

    Edit to add: I will try some memory testing the next day or so and post a stable set up for ProfJim et al.

    On my DDR2 board, 2.66D seem to work better than 2.4B at 467FSB. I get a higher memory clock along with a notch lower PL (Static tRead). Not sure if it will work the same way for DDR3 boards, but I thought it is worth mentioning.

    Worth mentioning indeed!

    I just tried using 2.66D strap like you said, and it does give better scores in Everest o_o

    I'll take screenshots in a bit

    You guys have no idea how much time you have saved me.
    Most excellent!

    Just a quick and dirty run through,
    static tRead is good at 7 though.....so far.......
