  1. iirc, Virtual counts all memory used by all processes all up, but applications using shareable addresses are not discounted so the virtual count will appear to be larger than the swap.

    the Swap space is the total available / in use memory from Physical + Page

    The page file is infact not doing anything on that drive and the access patterns for the page file aren't damaging to an SSD in any case.

    basically, its there if its needed and sometimes, it really is needed

  2. It is true that the single core turbo multiplier requires C state tech, but in my case, its not related

    When a user sets a multiplier under the stock multiplier, the cpu will always run at that multiplier. I found my asus bios tended to jump to 22x single core turbo at times even when i had turbo boost off and the cpu set to 20x, and 4Ghz was needing to much voltage.

    in my case, my clock rate is attained from 200x19x. 20x is the normal multiplier for this processor, with turbo being 21x(all cores) and 22x(single core). My CPU is always at 3800mhz regardless of c-state tech (with high performance profile set) so the turbo ratio is not applicable here

    I have heard another theory about this which sounds more likely.

    Nahalem was designed with a quad channel partition in mind, but the consumer level parts are Tri channel only. When the cpu is completely awake, 2 of the cores fight over dram latching and result in a slightly reduced throughput.

    When the cores are able to enter the c state, only the currently active cores attempt to latch and higher throughput is obtained.

    This doesn't explain why SBE throughput is not improved with C State tech however.

  3. That's a great catch! We're already doing test runs with Shared Memory enabled to see if we could reproduce the issue on our test systems. Meanwhile, can you please check what happens if you enable Shared Memory, but only have the CPU temperature enabled from the list of Ext.Applications items -- and no other items enabled.

    Second test run: have every items enabled there, disable Shared Memory, but enable Registry exporting.

    Those test runs may confirm whether one of the items cause a memory or handle leak, or whether the Shared Memory feature is generally at fault.

    I believe its a handle leak, memory use doesn't suddenly balloon and GDI count isn't excessive either.

  4. use HKLM just affects where the settings are written to, if the shared memory or gadget stuff was at fault it wouldn't affect it.

    try running without shared memory and without the desktop gadget.

    actually, i have a feeling its specifically Shared Memory causing the problem due to a mismanaged constants buffer

  5. the only likely explanation i can come up with is that when run in SLI, the 460 would only mirror the contents of the adapter output on each card and only display one instance of each port.

    Though i have 2 displays connected to my 275, so the appearance of 4 adapters on 600 series cards may be specific to kepler.
