    Default My XFAST RAM is slower than my HDD

    Hello, how do I speed up my RAM disk just a lil bit, my HDD is twice as fast.
    Pictures are my disks and memory benchmarks (Aida64).
    The OS is XP SP3 32bit.

    Thanks

    That seems strange, but maybe not. I'm wondering if Windows is causing the RAM drive to be using the pagefile, which is on the HDD. Since the RAM Disk's size is less than 1GB, the size of the Aida test data file might be causing the use of the page file. Notice the RAM Disk's access time in Aida, at 1.38ms it is incredibly slower than the RAM memory itself. That is shown in the memory benchmark to be 85ns, where 1 million ns = 1ms.

    Questions:

    Was the RAM drive empty when it was tested?

    Any idea how much data Aida used for the disk test?

    Have you tried another benchmarking program like Crystal Disk Mark, that allows you to adjust the size of the data used in the test? You can select 500MB, 100MB, or 50MB data file sizes, and it has a 32bit version you could use.

    My ram disk is 8gb and as-ssd is showing around 5000mps! Unfortunately my os started to act up when my ASRock utility crashed? I think it was caused by updating my bios?

    Yes.

    No idea.

    Yes. The results were similar to Aida (I'll quote the essential from CDM report):
    Code:

            Random Write 512KB :    86.033 MB/s
    Then I decided to stop/uninstall XFast Ram and use another RAM disk software.
    I installed imdisk and got the numbers I wanted from XFast RAM:

    I guess XFASTRAM is to blame given the fact that other RAM disk program is doing a good job with the same hardware and chipset drivers.

    I still hope XFast RAM can be fixed (Or my configuration can be fixed if it is broken from ASRock's point of view).

    Thanks,
    Mike

    P.S. The last test in Crystal Disk Mark, the "4kb QD=32" hangs the machine with XFast RAM. Always.
    With imdisk, no problem. There are two problems however with imdisk: it does not have autostart with Windows (cured by a bat file in autostart folder) and Aida can not test it as a disk.

    My results with a XFast RAM disk:

    My XFAST RAM is slower than my HDD-crystal-ram-disk1-png

    So XFast RAM does not seem to have issues on all systems, and yours and mine are quite different.

    Thay are not different because both motherboards are on the Motherboard Support and Download List for the XFast RAM utility. My OS and my RAM module are approved by ASRock for my motherboard.

    They are different because my motherboard with CPU, video and HDD cost as much as your RAM module alone. I doubt that could make any difference for XFast RAM.

    I fail to see any indication that XFast RAM should not work for RAM disk within the first 4 gigs.

    I meant what you said, that our systems are quite different. I agree that XFast RAM should use the unused memory in a 32bit OS, as it states just that in ASRock's information. But something is not right, and I don't know what it is.

    The problem is gone after BIOS upgrade, from factory's 1.40 to the latest 1.80.
