    Default Help with Gigabyte EP45-UD3R setup

    I registered here at these forums due to the level of support other people here have received. I purchased a Gigabyte EP45-UD3R 2 months ago and so far, the experience has been pretty good. Here is my setup:

    E8400 stock clocks
    Gigabyte EP45-UD3R
    G.SKILL F2-8000CL5D-4gbpi 2x2GB 2.1v DDR2-1000 kit
    PowerColor HD4830
    Western Digital Caviar se16 320GB
    Antec Signature 650w
    Antec P182

    There are a lot of settings in the BIOS that I am unsure of. I don't plan on oc'ing right now, what would be the best settings for the most stable system operation? And settings that would serve to get a fast bootup. Also, since I was running the memory at DDR2-800 (5-5-5-15 and AUTO subtiming), I tried to undervolt the memory, but any setting lower than 2.1v (even 2.0v) results in crashes. At 2.1v, they are gone however, is this normal?

    Default Re: Help with Gigabyte EP45-UD3R setup

    If it was me ,id try and get your memory running at its max rated speed first.
    Gskill mem is good for me.
    Use cpu-z and see if there is a performance profile for 400mhz(800mhz ddr2)and what voltage it specifies.
    The 2.1 v u have entered is probably only giving 2.07-2.08 when the pc is running,which is fine as long as it works.
    If the memory says 2.1 v for 1000mhz you might have to enter 2.12 or so.
    Have u tried a 3:00 multiplier?
    Once you get the memory at its rated speed you could move on to the cpu, with a lower memory multiplier as you build up.
    Auto settings could well be fine until u get to more extreme overclocks on the cpu,just have lots of testing utilities and monitoring utilities for temps etc..
    But getting the memory up to speed initially shouldnt really be an overclock.
    You might have to let the tRFC go on auto tho it should come out about 64 on auto at about 1000mhz,can allways lower it again if things stay stable.
    Do save your "good" bios tho with the F12 key on main bios screen so you can go back to it if needed.
    I think the 3:00 multiplier is the A one. if you want to try and hit 1000 with a B multiplier while keeping the cpu at around 3.0 G you will have to play around with the fsb and the cpu multiplier.
    nb setting the MCH frequency latch to auto will enable you to try the other multipliers.

    Thanks for the reply, kick. Yeah, 3.00 mem multiplier is available with the 400mhz strap and not the 333mhz one (B). I used CPU-Z and they have profile for 400mhz ddr2, it calls for 5-5-5-15 timings, tRC of 24, and voltage of 1.8v. However, when I tried 1.9v at 5-5-5-15 ddr2-800, I got crashes (2.1v at the same setting, very stable, passed memtest for 3hrs). It seems a little weird, but maybe this ram is only designed to work at a specific voltage, if there's not an incompatiblity.

    One thing in CPU-Z raises some concern for me. The "Core Voltage" reading seems to waver between 1.104v and 1.248v, is this normal?

    Default Re: Help with Gigabyte EP45-UD3R setup

    Your voltages are related to the following settings:

    CPU Enhanced Halt (C1E)................: [Enabled]
    CPU EIST Function.........................: [Enabled]

    Disable both for more stable voltages and stability, unless you want the system to automatically underclock your system from time to time. I would also manually set the CPU Vcore to the value shown in the MIT bios section.

    When you boot into the bios, the PC HEALTH section will show the actual voltages for CPU and MEMORY. When you're in windows, the cpu voltage will be a bit lower and this value will change somewhat depending on system load.

    Don't worry about not being able to undervolt your memory voltage.

    You are not limited to using the 333 MHz B-strap. Change this to 3.0A and your memory should run fine at its rated speed. With the 3.2B setting and some minor tweaking, your memory might run at 1066 MHz.

    After disabling both C1E and EIST, and CPU-Z now reads a solid 1.248v! At idle, that is.





    @kick and profJim: I was under the impression that the mch latch frequency can't be higher than the actual fsb, but it can be lower than the fsb without causing instablity, is this true? 3.00A is a 266MHz latch and should be fine, given that my fsb is 333MHz? Are there any drawbacks for using a lower latch , such as lower memory performance?

    Thanks for all the input so far, I appreciate the help.

    Each MCH strap has its own internal memory timings. There isn't an absolute best MCH strap. Using a memory multiplier of x.xx isn't always best with a higher or lower strap setting.

    On my rig, using the 2.0B memory multiplier yields better performance in the low to mid 400 MHz CPU FREQUENCY range. This is because I can use lower (i.e. tighter) memory timings for tRFC and tRD (Static tRead Value or Performance Level). At about 480 MHz or higher, the 2.0D strap lets me lower the tRD setting from 10 to 9. Above 510 MHz, the tRD value has to be increase by +1 with both of the straps. I've gone as high as 526 MHz in my testing, but stability testing with Prime95 fails almost immediately, even though I can run all the SuperPI benchmarks.

    I'm pretty sure that you could use the D-strap without any problem, especially if there was a reason why you wanted to use the 2.00D, 2.66D, or 3.33D multipliers to run your memory at a specific speed.

    I've used the 2.50A settings for a couple of test setups, but it didn't help with my cpu/memory goals. I'm severely limited by my 7X cpu multiplier.

    I've read a bit about memory straps, memory sub-timings, and bios voltage settings, usually resulting in a headache and a foggy mind.

    Default Re: Help with Gigabyte EP45-UD3R setup

    I changed the memory to 3.00A, which made it 1000MHz, and had 5-5-5-15, tRFC of 64 and auto subtiming. I benched both 2.40B (5-5-5-15, tRFC of 51, and auto subtiming) and 3.00A with Everest. I have the trial version so I only got read and latency numbers heh.












    Well, I changed back to 2.40B since it seemed to be faster. I might try 3.2B, but I might need to loosen some timings, cuz I tried it at 5-5-5-15 AUTO 2.24v and it crashed in game. It's fine though, because once I decide to OC to 3.6GHz with 400fsb bus, I'll be able to get 960MHz with 2.4B. I haven't decided to OC yet because the proc has proven to be plenty fast, and I like quiet (I've got a quiet case w/the fans on low).

    grats.
    Yeh I was just suggesting you get the memory running at 1000.Hey did you try it on turbo setting instead of standard just for testing?
    I run my mem on turbo.. I could just tighten the timings up manually but turbo is convenient.
    And yeh my memory will run 5-5-4-15 at 1000(big swingin mickey!) I just leave it on 5-5-5-15
    If you could get the mem at 1000 on 500fsb,youd notice an increase then.. course would have to clock the cpu up also

    Default Re: Help with Gigabyte EP45-UD3R setup

    Some of the memory settings on AUTO are killing you, especially:
    Static tRead Value (tRD) and tRFC. It might be the 3.0A strap requires tRD to be 11 instead of 8 (on the 2.40B strap). Quality DDR2-1000 memory can often run at 1066 MHz, so you can try the 3.20B strap, using your current 5-5-5-15 settings. Keep in mind that AUTO memory timings are usually on the conservative side.

    tRFC set at 48 - 52 will further improve memory performance, if your system remains stable.

    Performance Enhance = STANDARD is the best way to go while your tweaking. Once you have a stable system, try it on TURBO and verify that your system is still stable.

    If you run Everest -> Reports -> Benchmarks
    you'll get the full performance specs, and you you can save the report for comparison with other bios settings. I use the MHT file type for my saved reports.

    Synthetic benchmarks are useful for objective comparison, but don't always correlate with real world performance. One test you can run is to do a full anti-virus scan on your boot drive and see if there's any difference.

    I've wondered what Turbo mode does. I'm guessing it just tightens timings? I tried setting it on 2.4B (DDR2-800 5-5-5-15)and it made a marginal change in read performance (6912mb/sec to 6939mb/sec).

    When I dropped the tRFC to 52 on 3.00A (DDR2-1000 5-5-5-15) and static tRead of 11 on both channels, the everest read rose to 6772mb/sec (still lower than 2.4B with auto subtiming). When static tRead was set to 8 on both channels, the everest read rose again to around 7250mb/sec, a nice result! I'll have to memtest it to ensure stability first. 500fsb will surely increase it by a ton, but I'm scared the NB will get too hot/fry from the voltage.


    Thanks for all the help so far. It is really appreciated. I still have another question for you all. How do I set BIOS values for best performance with a single sata hard drive (the one mentioned in first post)? In particular, how do I enable NCQ with my HDD? I've already installed Windows (XP SP3) with the following settings, do I need to reinstall it?
