    Seems that memory performance are tthe issue here.
    Try to lower Static tRead Value as much as possible.

    changed mem from slots 2 and 4 to 1and 3. put tread static at 6 and 7, anything lower wouldnt post, and the bench scores and memory read/write values were pretty much the same.

    thx for trying though.

    It looks like something is wrong with the mem controler on the mobo? Not an expert in this area myself.

    Don't know really as the cache speed is low too, I get about dounle at 3GHz.

    Can you test with a different set of memory?
    Are you using memory slots #1 and #3?
    It looks like you are running with "mismatched" memory, from your report:
    DIMM # 1
    SMBus address 0x51
    Memory type DDR2
    Module format Regular UDIMM
    Manufacturer (ID) Kingmax Semiconductor (7F7F7F2500000000)
    Size 1024 MBytes
    Max bandwidth PC2-6400 (400 MHz)
    Part number KLDD48F-B8MN5
    Number of banks 1
    Data width 64 bits
    Correction None
    Nominal Voltage 1.80 Volts
    EPP no
    XMP no

    DIMM # 2
    SMBus address 0x53
    Memory type DDR2
    Module format Regular UDIMM
    Manufacturer (ID) Nanya Technology (7F7F7F0B00000000)
    Size 1024 MBytes
    Max bandwidth PC2-6400 (400 MHz)
    Part number M2Y1G64TU88G7B-AC
    Serial number 09A60853

    Number of banks 1
    Data width 64 bits
    Correction None
    Nominal Voltage 1.80 Volts
    EPP no
    XMP no

    2GB of memory with vista or win7 is probably hurting your performance.
    My results are using 8GB of 1066 rated memory running at 874MHz with 4-4-4-10 timings.
    My cpu speed is 3.496GHz using 437 x 8.0 settings with win7 SP1.

    I've tried both mem slots 1&3 and 2&4 same results. I guess the ram sticks are just from a different factory, but they both came sealed in the same kingmax packaging , were bought the same day and have the same stickers on them.

    I did just try out with different ram. I took 2x2gb sticks from my own p45 rig(had same sticks in a p35 ds3l as well). same brand ddr2 800. Bench scores were the same again.

    So it's definitely not a RAM stick issue I guess?

    In post #2, I asked you to add a detailed hardware list to your forum signature and some screen-shots (steps 1,2, and 4).
    We can best help you if you provide this information.
    Which operating system are you running?
    Are you sure that Optimized Bios Settings were loaded before you make any bios changes?

    With my P35-DS3L system, I was able to use a 100% overclock with my E2140 (1.6GHz) using 8 x 400MHz. For 24/7 operation, I ran the cpu at 3.0GHz. Overall performance was about 15% less than my E6550 running similar speeds. I don't know how high your P31 can overclock and still be stable.

    I didn't add it to my signature because its not my PC. im trying to fix my brothers PC. The overclock is stable(intel burn test can run for hours), and even at stock speed and stock voltage the problem is the same. The issue is not overclocking, but the significantly underperforming CPU at any clocks. And yes, I have tried optimized bios settings, reboot, and only then would i change stuff in the bios.

    GA-p31-ds3l revision 2, bios f8 (tried also f1, f6,f7,f9,f10a)
    2gb ram kingmax ddrII 800mhz
    5-5-5-15/18
    e6600 2.4ghz (9x266)/3ghz (9x333), same issue
    stock cooler (fan replaced with a 80mm PANAFLO) temps idle 30 C/intel burn test 60 C
    corsair 550vx
    8800gtx
    win7 64bit sp1
    Seagate Barracuda ST3160815AS 160GB
    19inch ASUS LCD monitor





    If I have missed something please let me know, and thx for helping posting pics you asked for in one second.

    also, added pics and system info to first post for easier viewing.

    Quick update: It seems i did not properly load optimized defaults I apologize for missing that important step. Its been a frustrating experience dealing with this, so again sorry.

    I have just done the optimized defaults thing.

    I booted up, cpu is now at 1.6Ghz(6x266). At this speed when i run nuclearus bench, i get a better score then at 3.ghz with setting described in BIOS template. 4994. mem read/write is now 5500/2153, instead of 2000/1000 and cache speeds are 91000/18000 instead of 78000/15000

    Then i rebooted again, and manually input all the settings for 3.0ghz, and the problem was back again., same low speeds for cache and memory write/read. So obviously a certain thing from the BIOS template I posted is the culprit.

    Should I now repost all the memset, cpuz and coretemp pics with optimized defaults in place?


    EDIT: tested games at optimized defaults, and even at 1.6ghz they are not slugish anymore, so we are definitely onto something :) Now just to figure out how to make it work at 2.4ghz or 3.ghz without the issue coming back :)

    What is the brand/model# of the power supply?
    I did some checking and the P31-DS3L is actually quite a good overclocking board.
    I would expect your posted benchmark score to be about 15% lower than my results.
    You could try running with some borrowed higher quality memory to make sure that there isn't some incompatibility with the current memory. Performance Level (aka Static tRead Value) = 8 is hurting performance, but this alone wouldn't account for a 50% lower score.

    The only thing that I can think of is that there is a very heavy load on your system from background tasks. This can be easily checked by viewing the average cpu usage is in Task Manager when your system is idle at the desktop.

    From the link to your memory, it can use 2.1 volts maximum and is rated for cas6 at 1066 speeds. Running at high memory speeds helps memory benchmark scores, but does next to nothing for gaming or program performance.

    I was surprised that running win7 x64 with 4GB of memory didn't help performance.
    You could overclock your system to 3.20GHz (8 x 400MHz) but I doubt that this would improve performance very much.

    Running IBT (IntelBurnTest) for hours at a time is next to worthless. IBT is good as a preliminary stress test when run for 5 - 10 loops. Many have found that their systems weren't stable when IBT was error free. Running the Prime95 tests often generates errors, sometimes after 4 - 8 hours or more. When IBT is running, Task Manager should show 100% cpu usage for both cores.

    The E6600 C2D is similar to my E6550 in performance at stock settings and when overclocked. Testing with a higher quality psu might help, but this is probably a long shot. Faulty motherboard? Maybe. Memory incompatibility? Another maybe.

    Nicely done with your posted screen-shots
