Much better AS SSD score after resume from sleep mode.

I was getting inconsistent results with AS SSD running my crucial M4. I finally realized the cause of the inconsistency was sleep mode. If I do a fresh boot, my ASS SSD score, particularly the sequential read and write, is significantly lower than it is after I resume from sleep. Once I resume from sleep, I can run the bench multiple times and get the same results.

I am using an X58A UD3R mobo, using the marvel sata 3 controller. I havn't had any problems with this controller (other than this), and I'm getting better overall performance than I would on the intel sata 2 with this SSD. I've done all the normal SSD tweaks such as deleting the Hibernate file with powercfg -h off, turning off system restore, customizing pagfile size to something not so huge, and turning off defrag.

Another thing my PC does that MIGHT be somehow related, is that after sleep mode, the cas timings on my ram goes from 8 to 7. Which is weird because if I changed it to 7 in bios without changing anything else, my PC won't even boot into windows.

  1. LOL You are the first one I have heard of that Sleep mode helped. Normally it just crashes the computer.

    When you are overclocking do you turn off turbo booost? You need to turn it off since you are looking for the most stable setting and turbo boost is just its own slight overclock.
  2. Since the big thing with ssd's is access times, I do not think it should be too bad unless you have real bad rates before sleep.

    I personally just used the Intel controller and it is still fast enough for day to day use without any issues.

    Yeah turbo boost is off, and I've had no other issues. I noticed the ram timing thing a long time ago, but it didn't seem to be a problem so I never bothered spending too much time on it. After sleep mode, I get just under 400MB/s (usually 395-398)sequential read, and 195MB/s write. (Which is pretty good for a crucial M4 on a marvel 9128 controller)If I do a fresh boot, it's like 355 and 155, but all the other numbers are about the same.
  4. Can you actually FEEL the difference? I ask this because lots of what users do is not sequential.

    Some users claim that the power saving options(c states ect) on motherboards hurts SSD performance, maybe try with them off.

    Yeah I already turned C-states off, it increased the 4k and 4k-64Thrd speeds in AS SSD. And no I can't exactly tell the difference, it's just something I would like to figure out.
  6. bios up to date?

    Yes, although the last bios update for my board was from Jan 2012.
