    Well those are loose timings, but I am sure you know that right?

    Be sure your kits match if you want to go 8GB. What do you want me to advise on, your current settings above for 4GB or 8GB? For either you will need to set your ram voltage higher, and set your own MCH 1.2-1.24 for 4GB and maybe 1.26-1.3 for 8GB. Vtt may also need increased and manually set

    Please be gentle with me. My last bios tweaks were on an AT-286 in 1988. I have just today installed EasyTune for the first time ever. By loose timings you mean tRFC could be lower?

    I will follow the kind advise around here and match my RAM pairs. I have located a additional set of 4GB F2-8800 which should arrive in the next few days.

    What are the necessary settings to run 8GB successfully?
    Are below voltages safe to run 24/7?

    My current settings (stable in a 11 hours Prime95 run):

    No worries, I was just letting you know the timings were loose is all. I meant several of them actually, not just tRFC. Performance Level (tRD Static tRead Value in the BIOS) is very loose, you can start with lowering that one to 8-9 for now. Then I will help you with the rest once you get your second kit of ram.

    You likely will not be able to run 1066Mhz with 8GB, just letting you know now before you get it installed, or purchase it if that was your hopes.

    I will help you with 8GB though once you get it, if you do. When you do, if so, I will need your full settings in a template that you try and fail with before I can advise on how to proceed. Normally you need more Vdimm, MCH, and looser timings for 8GB

    Your PLL is way to high, try 1.54-1.58, MCH Core is also to high for 4GB 1.2-1.24 should be plenty for now

    Ok, it has been a while, but now the second RAM set is in. 4GB G.Skill PC2-8800. Same as the first set. The new kit at first seemed not as capable as the old one. I tested both kits separately and initially wasn't able to get the speced 1100MHz out of the new one even when installed singular.

    But after 12 hours break-in (is there such a thing in RAM chips?) things started to improve. I applied some aggressive(?) voltage settings and got them going.

    My current settings have been stable under IBT and Prime95 for 2 hours so far.
    I would be more than happy to leave them this way. The only question is: are these voltages safe for 24/7 usage? Max temp CPU is 64C.

    CPU w/ 4GB posts up to 4GHz, boots Windows up to 3.84. Somehow I thing the board gets unstable at FSB > 460? I run the ICH10R in RAID config.

    Dropped back a shade to FSB 440 and got 24 hours P95 stable.
    Memory relaxed slightly to 1100@5-5-5-15-72 (auto)
    Removed EasyTune and Memset which gave me some headache at Win boot.
    Finally I got a stable and fast VMWare base.

    Hello,

    I have this motherboard, the GA-EP45-DS4P and I'm having issues with it (well technically I'm having the same issues with it as I did the GA-P35-DQ6)

    Here's the story so far, and apologies in advance for bumping this thread.

    I decided to get to the bottom of this crashing problem. Typically the the computer would either last a few days, or it would last maybe an hour. I've chalked this up to the bios sometimes using the 5-5-5-15 settings to crash and the 5-7-7-21 settings that don't crash as often.

    So I started by changing the thermal paste, believing it to be the CPU overheating. That lead me into replacing the motherboard, power supply and finally the stock cooler with something much larger. 300$ later, still no closer.

    So this leaves me with the CPU or the RAM
    The CPU is an Intel Xeon X3220 B3 stepping
    The RAM is Patriot PDC22G8500ELK 4 x 1GB modules

    The RAM has these settings:

    The motherboard right now, I've run through so many settings that it's getting silly. What are the correct settings to run this at?
    All voltages are running at stock (The RAM however runs at 2.2V despite what the SPD says according to EastTune6.)

    I'm not sure how, or if there is a way to force the memory to work properly. If only one module is installed, it will normally just work, as it's not running in dual channel mode. The second a second module is installed, problems start happening, but it isn't till the 4th module is installed that the mean tim ebetween crashes is reduced to less than an hour.

    My intention is not to overclock the thing, but it seems to me that the RAM is really Overclocked to begin with. Is there a way to force it to run at the PC6400 settings, even to test?

    Memtest86+ at 5-5-5-15 will always error out on test #5
    at 5-7-7-21 it may complete it, but eventually it will fail after like an hour (all modules installed)

    I tried emailing the manufacturer of the RAM and they first suggested the motherboard slot might be bad, which seems impossible considering it's new.
    I then wrote back and asked about other settings and they suggested trfc to 72 or higher, trrd to 6, or running 5-6-6-18 at 1020Mhz (how?)

    So basically I'd like to know what settings I should be running this at to make it stable with all 4GB of memory. If I have to impair the performance a bit,that's fine.

    You might want to post your full EasyTune Frequency and Voltage screens here for the knowledgeable people around to help. From my limited experience I would definitely think it is the RAM settings. 4 modules will require more voltage and/or relaxed settings than 2.
    I would start with setting DRAM voltage to 2.3v as this seems to be the recommended setting for your RAM type: AnandTech: Patriot Introduces DDR2-1066. MCH Core to 1.4v and MCH Ref to 0.8v made my RAM rock stable.

    Thank you for your response,

    Voltages


    Frequencies (currently trying to underclock it):


    Again, I'm not able to get to boot at 800Mhz, only 1066. This is the first time I had it boot up at less than 1066. Otherwise everything on those two panels is the same as when it powers on at 1066.

    Are you trying to adjust your bios settings via EasyTune? I would advise not to do so. In fact, I did this while having the issues with my setup and found that it only adds more headaches at win boot up. Do your whole setup only via bios.
    Try this:
    - uninstall EasyTune
    - Upgrade to the latest bios version
    - reset to "optimized settings" in bios
    If system is unstable, do in this order:
    - MCH Core to 1.3v
    - DRAM voltage to 2.3v
    If still no luck, switch to manual settings for DRAM in bios and go down in steps of 10-20 until stable.
