    Default Memory bench results PC8500

    Was toying around with Everest. Just curious if I'm where I should be in regards to my memory.

    Read : 8759 MB/s
    Write : 9462 MB/s
    Copy : 9302 MB/s

    Latency : 60 ns

    5-5-5-15 CR2
    2.4B strap effective speed 1068 Mhz

    The rest is in my sig. Thanks

    Looks good, can you run 2.66D? Or how does 2.00D score?

    What tRD are you using?

    2.66D strap would be too much. I'm trying to avoid going too much over its rated speed. My tRFC is 60, my tRD is 4. EDIT: I had previously confused the two on paper ;)

    Also, is it normal for my READ to be slower then my write / copy? You'd think Read would be quickest..

    Ahh well I didn't know your FSB, I see it now though :) so I thought maybe you could try 2.66D

    tRD 4 is likely not very stable, so if you run into stability issues you may need to use 5-7

    That just depends on the memory, about Read, but in general yes read is normally faster. Try 2.00D with tRD 8-9 and see how it scores

    Changed my tRD to 5 and my tRFC to 58.

    Numbers didn't change too much:

    Read: 8781 MB/s
    Write: 9458 MB/s
    Copy: 9412 MB/s
    Latency: 60 ns

    If I leave the tRD at "5" instead of "4" will I get a better stability long term? If so I will leave it at that.

    I tried the 2.0D strap but I got basically the same numbers above "minus" 100 - 200 MB/s here and there.

    lemme know, thanks :)


    p.s. I went to 4.25Ghz last night out of curiosity. But I had to bump my load voltage from 1.328 to 1.35v. I didnt see much gain at all, considering I was now running almost 10C hotter on load. So I went back to 4.0Ghz.

    Ya tRD 5 may be stable longer, but if you are stable with 4 you are fine to use it.

    Well like you say, if "5" is supposed to be more stable, and it doesn't take away from my performance, Id much rather keep it :)

    Any idea as to why my read is 500 MB/s below my copy / write? Is it something I should address?

    Just looking to solidify this build at 4.0Ghz

    Thanks for any input :)

    Leaving it at this :



    Adv. Timings

    tRRD : 5
    WRD : 4
    Write Precharge : 8
    tRFC : 52
    Read Precharge: 4

    2.4B strap : 1068Mhz

    Read: 8800 MB/s
    Write: 9500 MB/s
    Copy: 9400 MB/s
    Latency: 59ns

    ^ Thats about the best I can pull off stable. Just ran Prime95 blends for 4 hours with no errors.

    Temps didn't break 59C. Im content

    Wel tRD 4 IS better for performance, but it may be unstable at the FSB you are using, actually I am surprised you can boot with 4 or 5 at that FSB.

    I'd assume your write/copy are higher than your reads because of your super low tRD, normal tRD for P45 and 400+ FSB would be 6-8 on the B strap and 8-9 on the D strap
