    So what are you using now? If stock, please post for me your fulll settings, and a image os Memset from windows and I will advise you. You said Auto or stock works but manually does not right? Just want to see memset so I can see what Auto is giving you

    RMA'd the board today, Gigabyte told me I have a bad board. Went with the refund from NewEgg so now I'm in the market again. Looking to overclock E8400 to 4.0 with 4GB OCZ Reaper ram (PC8500) and GTX 260. First time builder so all of this is new to me. Are there any other boards that would fit my bill. Looking to spend under $200.

    Thanks

    I would get a GA-P45-DS4/DS4P if it was me, this is what I am using now (Thanks Gigabyte and Mr.Tweak >>>
    Newegg.com - GIGABYTE GA-EP45-DS4P LGA 775 Intel P45 ATX Intel Motherboard - Intel Motherboards

    If you did not like all the BIOS options of the P45, maybe you should get a P35 then. They are great overclockers with much less BIOS settings and will save you some cash as well. If you would like me to find you a EP35-DS4 or DQ6 at a respectable US place let me know, as newegg is out of stock

    Might not RMA the board anymore because I have it working and stable at 3.8, basically by only setting the CPU Frequency to 423 bumping the RAM voltage to 2.2V, MCH to 400, and setting driving strength to 1066. Everything ran stable then I decided to add the below vales that you gave me as well: timings, voltages, ect. Below is what I am currently running at and it's running stable as well. It seems that the only difference was giving the ram 2.2v (never even had to add voltage to MCH core w/ 4Gb).

    Don't think there's a need to RMA the board anymore, but my concern is my current values running at 3.8GHz are not pulling any better 3DMark06 scores than my 3.6 non-stable settings. 15700 w/ GTX 260 and 4Gb's w/ cores running at 53/54* C. Ram timings?

    Thanks for the help.

    Timings are now 5 5 5 15 and picked up 90 pts. in 3DMark06 compared to the 5 5 5 18.

    How can I tell if the GPU is running at the right settings? Easy Tune 6 says my GTX 260 is running at a Core Clock of 300 and Memory Clock of 100 which doesn't seem right. This could be the reason for my low 3DMark06 scores.

    Settings for the card should be Core 640, Mem Bus 448, and Mem Speed 2300. If this is indeed a problem, what is a good program to use to overclock the GPU back to factory settings? RivaTurner? Nvidia's tuning software only gives me blue screens.

    Thanks

    First I would add some MCH voltage and back that Ram voltage down to 2.1, 2.2 is VERY hot on your ram and is not needed likely. But I guess it may be with that high ram speed, I would personally add more MCH and see if you can bring down ram Voltage though.

    As for your speed not being noticed from 3.6 and 3.8, you have some very loose ram timings once you tighten those up you may have much better results

    Check with GPU-z to be sure you are running at x16 instead of x4 or x8 or x1! >>>
    GPU-Z Video card GPU Information Utility

    And I am not sure about Nvidia cards, but I think they do clock down unless you are gaming or running GFX benchmark. Run these tests below and see if those clocks change as the tests start to run

    FurMark (Dont make the window too big, this WILL make your card HOT) >>>
    FurMark v1.4.0 download from Guru3D.com

    LightSmark >>>
    LIGHTSMARK - next generation lighting benchmark

    See if you can get these changes to work >>>

    Robust Graphics Booster ...............: Fast or Turbo

    (G)MCH Frequency Latch...............: 400 << Try 333, Only change this and try it first.
    System Memory Multiplier ..............: 2.66 << if you use 333 above you will have to use a different ram multi though (2.0, 2.4, 3.2, or 4.0) 333 will perform better I think for your ram speed if you can get it to boot thru.
    Memory Frequency (Mhz) ..............: 1125Mhz
    DRAM Timing Selectable ................: [Manual]

    Standard Timing Control
    CAS Latency Time........................ 5
    tRCD ......................................... 5
    tRP'........................................... 5
    tRAS.......................................... 18

    Advanced Timing Control
    tRRD...........................................4 << Maybe 3
    tWTR..........................................12 << For sure can come down. Likely 3-5
    tWR............................................14 << For sure can come down. Likely 5-8
    tRFC...........................................54 << maybe 50-52, maybe not at that speed though
    tRTP...........................................4 << 2-3
    Command Rate (CMD) ....................:2

    Set Driving Strength Profile to 1066 for both channels << Set to 1200

    Channel A & B
    Static tRead Value.........................:8 (if you get 333 MCH to work, you can use 7)

    MCH is set @ 333 w/ Multiplier @ 2.4 for Mem Freq @ 1050Mhz
    Graphic Booster = Turbo
    Could not set the tRead Values to 7, kept at 8
    Could not set the Driving Strength to 1200, kept at 1066
    Able to lower RAM voltage to 2.1V & MCH voltage up to 1.24V with computer restarting properly now (interesting as this seemed to be the previous problem)

    CPU-Z confirms 16X2.0 PCI with correct clocks as well. You were correct in that it was clocking down when not needing the power.

    3DMark06: 15720 with cores running at 53/54*C (no change)

    FurMark: 3585 @ 1280X1024
    3375 @ 1680X1050

    LightSmark: 670FPS @ 1280X1024
    558FPS @ 1680X1050

    GPU never broke 53*C in the above tests (Full Screen), actually only one of the three GPU temps reached 53*, the other two were low 40/high 30* C. Fan speed never moved from 40% ~ 1450 RPM either which seems interesting to me.

    CPU cores during all tests never broke 56*C

    In regards to RAM runnig at 2.2V, the sticks (at least heat pipes, OCZ Reapers) remained cool to the touch even under heavy load. Website claims 2.1V, sticker on sticks say 2.2V

    Looks good. I thought maybe it was being clocked down. You can disable that I think, but not sure how as I do not use Nvidia anymore. At least I think you can with some cards, It may be in RivaTuner or your Nvidia CP.

    Well the thing is about voltages for RAM, what you see on the sticks or the site is the warrantied amount, not what it will need. Most 2.2 or 2.1 will do fine at 2.0 or less, not at the speeds you are running though, but at stock most will do stock speeds undervolted

    As for your fan speeds, you can set defined Speed intervals based on temps if you like with AtiTool if you think it should run faster then it is now. It may be set to only do 40% up till a certain Temp

    So are my scores above good? From what I have been reading, people scoring high on the 3DMark06 are using overclocked quads. I don't know how my FurMark/LightSmark compare. What's a good program to use to see FPS in games?

    Also, my memory with the 2.4 multiplier is currently low compared to the 1150 people are running. What would it take to run 4-4.2 CPU and have memory around 1150? Just bump up speed and voltage?

    Thinking of keeping the board now (:
