    IBT and LinX are only good for a quick and dirty preliminary test to see if your system might be stable.
    I have seen many Prime95 stress tests fail within one to three hours when IBT or LinX had no errors.
    I only run a brief LinX test for 10 - 15 minutes using 3072 or 4096MB of memory.

    The following are my Prime95 guidelines:
    • A one hour test with no errors means that the system might be marginally stable.
    • A three hour test with no errors means that the system is possibly stable.
    • A six hour test with no errors means that the system is probably stable.
    • An eight hour or longer test with no errors means that the system is stable.

    The problem is that until you have run each of the three Prime95 tests (small FFT, large FFT and Blend) for at least eight hours with no errors, you don't know if your system is really stable.

    Years ago the consensus was that for a fully stable system, each of the Prime95 tests had to run for at least 24 hours with no errors.

    Thanks for the replay!
    What about this liquid cooling click here
    Is this compatible with 775 socket?
    In this post review, on the bottom of the page it says its compatible with old 775 sockets
    Also, this cooling is cheap, 57 dollars and on ebay is abit more expensive, and with blue leds like my case, it will fit perfect, except the socket...
    For memory timings i will try later and post what i did and if its stable.

    I checked out the DeepCool product catalogs for 2015 and 2016 and their water cooling setups say that they are compatible with Intel: LGA2011-v3/2011/1366/1156/1155/1150 motherboards and they don't include 775 motherboards. Quite a few of their air cooled cpu coolers are compatible with 775 motherboards.

    In general lower cost water cooling setups will offer cooling performance that is similar to higher end air cooled cpu coolers.

    If you go with a 240mm water cooling radiator make sure that it will not interfere with motherboard components. You probably will not be able to use a push/pull fan setup unless you have a large tower case. Most radiators are 25mm or 37mm thick and most fans are 25mm thick.

    The performance of my Cooler Master Seidon 120XL setup was similar to Corsair's H80 and H90 water cooling kits and the lower end Corsair H50 and H60 kits were not as good.


    With your memory changes you will probably need to make some additional memory voltage and/or timing tweaks.

    Lets leave the watercooling for later, and now focus on the clocks :P
    Here is screens:

    Changed the timings as u suggested, what should i use to test for stability and how much time i should run it?
    Can i get faster timings or this is the max?

    re: watercooling
    Contact tech support at DeepCool and see if they have any AIO water cooling kits that are compatible with LGA775 motherboards.


    re: memory
    Your different brands and models of memory modules seems to be doing well.

    I've tested several different 4 x 2GB ddr2-1066 memory kits with memory speeds up to 876MJHz with 4-4-4-10 or 4-4-4-12 primary timings.
    My 4 x 2GB OCZ Repaer ddr2-1066 memory kits were also stable with these settings up to 900MHz.

    All of my memory kits are rated for 1066MHz using 2 x 2GB of memory and I've had no stability issues with running 4 x 2GB of memory at speeds that range from 1066 to 1100MHz. My HyperX 4 x 2GB memory kit is stable up to 1092MHz but I'm running it at 1080MHz with my 3.825GHz (8.5 x 450) cpu settings. In x5450 on ep43-s3l overclock help, post #3 in your original thread I posted a detailed screen-shot of my 4.012GHz (8.5 x 472MHz) setup with 2 x 4GB of memory running at 944MHz with 5-5-4-12 memory timings. The overall performance with both of these setups is very close.

    Artificial memory benchmarks should always be higher with faster memory speeds, but there will be little or no difference with real world software when you are running running with cas4 memory timings in the sub 900MHz speed range compared with using cas5 timings in the mid 900MHz range up to 1100MHz. The only exception might be when doing extensive music or video encoding/rendering or doing intensive PhotoShop image manipulation with large RAW photographs.

    I recommend that your run each of the Prime95 tests for at least 3 -4 hours to see if your system is probably stable.
    The Large FFT test primarily works your memory subsystem, but the Blend test spends about half of its time stressing your memory.
    Keep in mind that any two of the three Prime95 may run for many hours with no worker errors, only to have the third test fail.
    There are no short cuts when it comes to stress testing your system.

    The attached photo shows my 878MHz, 4-4-4-10 stable memory settings with my P35-DS3L motherboard. The Performance Level = 7 will not be stable with P45 motherboards, but with 4-4-4-10 (or 12) settings, performance level = 8 should be stable.
    My P45 4.012GHz, 944MHz settings requires performance level = 10.
    My P45 3.825GHz, 1080MHz settings requires performance level = 8.

    You will probably need to use 2.00 - 2.10 volts for your memory voltage when using cas4 800MHz+ or cas5 900MHz+ settings.
    Hopefully the SPD settings from the G.Skill F28000CL5-2GBPQ, EPP#1 column will be stable with 1000MHz or higher memory speeds.
    For memory speeds higher than about 950MHz, tRFC will probably need to be in the 60 -72 range.

    If your DRAM Voltage was 2.00 volts you might need to increase it, possibly up to 2.10 volts.

    It's possible that using AUTO for some of the memory related settings might give you a stable but not quite optimized setup.
    With AUTO settings for the primary memory timings, I remember seeing some Gigabyte P35 and P45 motherboards give 5-6-6-17 primary memory timings when the memory speed was set to 1066MHz; the idea being that bios would err on the conservative side so that the system would boot and appear to be stable.

    Another option is to use the 2.40 memory multiplier with your 444 bus speed for 2.40 x 444MHz = 1066MHz with 5-5-5-15 memory timings and tRFC =64.
    Your G.Skill memory is rated for 1000MHz with 5-5-5-15 timings but I don't know if the A-Data memory will do 1000MHz or 1066MHz speeds.
    I know that you want to run your cpu at 4.0GHz but you might need to lower the 444MHz bus speed temporarily to find stable settings with a somewhat lower memory speed.

    It's best if you also post an updated bios template where you make it easy to see which settings were changed.

    Also double check what HWiNFO reports as the highest cpu core temperatures for each core and make sure that none of the cores were throttled down due to core temperatures that got too hot.

    This Temps are from whole day, running prime.
    Copy my template and mark the settings u think i should change to and witch value.
    Also take a look at my voltages, i wanna know if they are good, or i can put some of em lower.
    Gonna try to up my ram to 1000 or 1066 and do some testing with the same settings.



    EDIT:

    Running prime now, gonna post updates later.
    changed the timings 5-5-5-15, tRFC 65 cuz i had no 64 on the list and running on 1067Mhz ram, 444 FSB. All the rest settings are the same

    Your goal right now is to get your system stable, even if it means lowering memory performance a little.
    Final performance tweaking will be the last step after you have reached your overclocking goals.

    Try the following, but only change one or two at a time:
    • set the bus speed to 417MHz so that you can test your memory at 1000MHz speeds with 5-5-5-15 primary memory timings.
    • set Mem.OC Charger to Enabled which migh help enhance DRAM overclocking.
    • set Ai Clock Twister from AUTO to light or lighter to enhance DRAM compatibility.
    • set Common Performance Level from 11 to 15 which might help with memory compatibility.
    • raising FSB Termination Voltage in small steps often helps with delaying or eliminating Prime95 worker errors.


    There is very little information on adjusting CPU Clock Skew and NB Clock Skew settings. With my EP45-UD3P motherboard I found that increasing the NB Clock Skew setting two clicks helped solve my system's stability issues with my 3.80GHz - 4.00GHz settings. YMMV.

    Changing multiple bios settings at one time can cause additional problems or it might help with stability. The problem is with multiple changes at one time makes it impossible to determine which specific changes hurt or helped. I usually only change one or two settings at the same time and then test my new settings.

    This is the most stable i found, and i will keep my config like this, tweaking ram a little wont change much, thanks for your help profJim, i finally found a stable setup for my xeon 5450 with P45 on Asus P5Q-E.
    I'm gonna lower voltages to see if i can get a little less core temps!
    Thanks again profJim!
