    Thumbs up Re: System Freezing Constantly GA-EP45-DS3L

    Yeah, 3.20 was a TERRIBLE idea. Instead I went backwards to 2.00B. Now my FSB and DRAM are 1 to one and two hours of running test three shows 0 errors. Having the multiplyer at 2.00 won't decrease my computer's performance, right? All other timings are set to auto. Memset shows tRFC at 36 instead of 42, but the system ran memtest fine and I'm experiencing no instability so far, but then again the computer has only been running for about an hour so far.

    You'll be running your memory at just 667Mhz now with a 2.00x memory multiplier.
    You need to try all the different 2.40 Multipliers, ie 2.40A, 2.40B and so on, if you have them available, so you can get your memory to its default of 800Mhz.

    What concerns me though is your tRFC Value. It sounds like you are not setting this manually in the bios and Auto (from SPD) is taking over and setting an unsuitable too low value.
    You should be able to disable Auto on the global advance memory options and set Auto for each value BAR tRFC, which you need to set to 56. Your Setup will hate anything less than that with 4GB of memory at 800Mhz (Your memorys nominal frequency).
    Now you are running your memory far less than it's rating and you can naturally get away with much tighter values. However they will not make up on raw speed throughput, you do need a higher frequency for that, ie 800Mhz (not 667Mhz).

    Before I start changing values again, can I flash my BIOS to F10 (latest) with the 1-stick settings I had with 1 stick in RAM? I'm running F6 and F7 says it has "memory improvements" or something to that effect. I'm assuming F10 has all those improvements and more. Can I flash from the stable settings I have to F10 and THEN load optimized defaults? Or must I have optimized defaults on befor I flash as well? I'm going to be flashing using FLASHSPI and a USB disk as my hdd is ntfs and I have no floppy drive.

    Also, how exactly do I boot from a USB flashdrive? There were several USB options when listing what device to boot from.

    If your system is stable now and check with MemTest with one pass that the memory is ok, yes you could flash it up to the latest bios.

    You don't need a bootable floppy or USB stick (although its an option). All you need to do is:-

    1) Download latest bios from GB site. Check you have the right page for your board and revision.
    2) Download and install Winrar (if you haven't got it).
    3) Test the archive is OK within Winrar
    4) Run Scandisk/Checkdisk on your USB stick - just to make sure its ok.
    5) Extract Just the Bios Image (Not flash SPI) to your USB stick.
    6) Plug in stick to your PC
    7) Enter Q-Flash as you either Boot from Cold or Restart your PC by hitting the "End" key. Check the guide here http://forums.tweaktown.com/f69/bios...h-guide-27576/
    8) Also in addition to the guide Disable "Keep DMI pool" on the menu.
    9) Browse to new bios image and select. Let the process run.
    10) You may get a screen that says Checksum = 1234 etc and do you want to continue.
    11) Continue and let the whole process complete without interuption.
    12) Once the process has full completed, escape out.
    13) Upon reboot enter the bios and enter up the Load Optimised Defaults heading on the bios MAIN menu page. (note if you are on a specific page your only load defaults for that page - you basically want to Globally load up the defaults)
    14) Save and exit.
    15) Pc will reboot and you can enter the bios again to setup your specifics.

    Successfully flashed to F10 bios. Using anything other than 2.00B or 2.40B seems to throw the rig into infinite reboot cycles. I'm back to the 667MHz setup for now. I've also set the timing tRFC to 56, though my sticks do advertise running at 42. Having 56 does not rid of the 40404040 mistake, however. I'll run this problem by the ram people, as well. If you have specific timings to try out, I'll give them a shot, too. I'll try Lsdmeasap's timings in that first post when I find the time (probably Thursday). In the meantime, I'm not putting my system in danger by running at 667MHz, am I?

    Here are some memset screenshots. Apparently auto has also reduced my tRAS from 18 to 15.

    Your system will be absolutely fine running the Ram at 667Mhz. Hopefully it's just a setting that's stopping you from running your Ram at 800Mhz, although it could be faulty Ram.
    I'm one of these people who thinks far too much is RMA'ed as an easy option. Obviously there are times when things are faulty and do need to be returned.

    Lsdme, will be able to give you some relaxed settings for your P45 to see if the ram will work at 800Mhz.
    I assume too, you have set "Performance Enhance" to Standard?

    You assume correctly. This is my friend's ram and he tested it on his system before he gave it to me. He was running it on SPD settings. I also apparently made a mistake when I said I set the tRFC to 56... Set it to 42 instead, because it was like 36 before.

    You should try tRFC at 56

    Also you could manually adjust in the bios your main timings to 5-5-5-18.

    What voltage are you operating the Ram at and what is Corsair's maximum voltage rating for this product?

    Did you check to see if you have more than one 2.40 multiplier? ie with a different suffix?

    Ram is running at 1.8 Volts. I tried running it up to 2.0V before, but still got the 40404040 error. I did not check for other 2.40's specifically, as when I changed to 3.00A which was supposed to give me 800MHz, my system did not boot and went into a reboot cycle.

    Nope.....

    I thought I read that you have a E8400, which is a 1333/333 CPU. Which means your Cpu Host Frequency (if it's at stock) will be 333Mhz.

    Then you take your 333.xxMhz** and multiply that will the Memory Multiplier.

    So 333 x 2.40A/B/C/D = 800Mhz ie PC6400 RAM

    the 3.00A multiplier would have run your Ram at 333 x 3.00 = 1000Mhz

    ** Note that most of the CPU host frequencies have a decimal point, so for instance 333.33 is stated as 333 for simplicity.

    I did not check for other 2.40's specifically
    Why? The suffixes indicate that the memory multiplier is "strapped" to a different clock reference. Although the multiplier remains the same and so the resultant speed, the way it's derived can make all the difference to stability.
    However not all variations are available in your list, but now you've flashed the bios you should have a look to see what is available to you.
