    The copy of the bios that you save to a disk or usb is meant to be reloaded if needed, such as if your saved bios profiles get corrupted or you accidentally overwrite a saved bios.

    You can reuse any of the eight saved bios slots any time you press F11 by going down to a particular saved bios slot. I always change the saved bios name before I overwrite the previous bios settings saved in any slot. When I save a profile that might or might not be stable, I put a question mark after the profile name, and once it is fully stable, I remove the question mark from the end of the name.

    I fill out and print a hard copy of each bios profile and add notes on each page that describes what worked and what failed. This is an excellent tool that helps you see at a glance what seemed to help and/or what made things worse.

    I figured it out, read my last post. Now im at stable 421 FSB at 3.70Ghz (412x9) PCI-E 101 and Vcore 1.25626V, all rest settings are the same exept the tRD (Static tRead Value at 10 as u said on both A and D channels).
    This FSB and vcore are stable from the beginning, and the pci-e was on 100 before, i will get it back to 100 after i finish with this post, the system is stable with those settings, all i want is to hit higher, like 4.00Ghz if possible. I raise the vcore before to higher voltage and the fsb too, but no luck, i think there is something that is missing, like ram timings, ram voltage, and other voltages. But u know the best, waiting for your answer :D

    I don't know what you mean by a stable setup.
    How many different Prime95 tests did you run?
    How long did you run each test?

    I can't advise you unless you post a detailed screenshot and include an updated bios settings template.
    It doesn't help if you say "I only changed the following settings".
    Without visual proof, it's too easy to make mistakes if you only post an updated bios template.

    In Lukes Xeon O/C thread, he switched to an EP45-UD3P motherboard with his X5460 cpu starting with post #383.

    There is a lot of good information in Luke's thread, check it out.

    For cpu speeds at or near 4.00GHz you will probably need to set CPU Vcore close to 1.40 volts .
    I've found that when stress testing, HWiNFO will show Vcore close to 1.296 volts or possibly a bit higher while the tests are running.
    Unless you have an excellent, higher end cpu cooler, cpu temperatures will be too high.

    I just noticed that you are using two different memory modules:
    • DIMM1: Patriot Memory PSD22G80026 2 GB DDR2-800 DDR2 SDRAM (6-6-6-18 @ 400 MHz)
    • DIMM3: A-Data ELQVE1B1615ZG 2 GB DDR2-800 DDR2 SDRAM (5-5-5-18 @ 400 MHz)

    Using mixed brands or models of memory often leads to stability problems, but sometimes a mismatched memory setup can be stable.


    Dram Voltage = 2.00 might help

    Higher CPU Termination (aka VTT) might help, but it's best to set VTT at least 0.05 volts lower than CPU Vcore.

    MCH Clock Skew = 50 or 100 might help with higher FSB settings.


    This is a list of the available memory straps and the memory multipliers that can be used with each memory strap.
    With FSB at 400MHz or higher, you should use the B or D memory straps.
    Memory performance will be slightly better with the B memory strap, but some users found it easier to use the D memory strap above 400MHz.

    This is the bios setttings i have right now, and the Computer is stable, no boot bios loops restarts, i've used it whole day, surfing the internet, listening to music and playing League of Legends on max quality in the Video menu. Im using Air cooling on my PC, i have CM Hyper 212 Plus with dual fans on my CPU, using 120mm fan at front of my PC to get air into the case, using 90mm fan at the back to get the hot air from the PC out, using another 90mm fan from the side to get a fresh air inside (this fan is more for the GPU, to bring a fresh air to the GPU also for the whole PC, the gpu has x2 fans (idk if you need this info) and the PSU has one 120mm fan to get the hot air from the psu out also from the PC (the fan its faced down to the CPU and gettin the hot air out). Here are screenshots from a Standard and High IBT test and hwinfo temps (max temps).

    Standard





    High





    CPU-Z:



    ET6:



    Memset:



    Fans in my pc:



    Also forgot to mention, both of the tests, hits the max temp value and never goes that high again, its like 2-4 temp lower then the max temps showed on the picture.

    About the RAM, tell me which ram should i keep and which ram should i change, i can trade it with someone 2gb ddr2 800 for 2gb ddr2 800 but the timings to be the same on my pc.

    Now lets start from the beginning, with this info i told ya just now tell me what to do in the bios and tell me about the RAM modules, which should i change and which should i keep.
    I plan to buy 1066Mhz DDR2 Ram, but not sure when i will get them, with those i will be able to clock more i guess, and if im lucky to find a cheap p45 chipset mb i will buy that too, but my country is limited with items, no p45 mb's atm and ram on 1066 mhz, all i can think of its ebay.
    I think i provided enough information, if u need more info about my computer specs, click under my forum name, i got them all there. I guess this info will be enough to start overclocking my machine and trying to get the highest clock with this specs. ( till i get my ram modules or if i get them at all ).
    Thanks Jim you are the best!

    Default Re: x5450 on ep43-s3l overclock help

    Okay, i found a ddr2 800 2gb module, put it on 2nd slot and now i have 6gb of ram, the 1st and 2nd slot ram modules are the same, same timings and the rest, and the 3rd slot ram module is different, should i put the 2nd slot ram module to the 3rd one so they work better in dual channel and change the 3rd slot module to the 2nd slot and run the PC with 6GB of ram or should i just get the 3rd ram module with the different timings out of the pc and dont use it? Here is a cpu-z:



    Here is passmark test on the memory.

    4GB(same timings on slot 1 and slot 3) page1



    4GB(same timings on slot 1 and slot 3) page2



    Now i put the 3rd ram module i have but that one is a bit different from the two at slot 1 and 3. So i put this module at slot 2 and here are the passmark test on 6gb memory.

    6gb memory test page 1



    6gb memory test page 2



    Seems like with 4gb x2 ram modules on slot 1 and 2 is faster then 6gb ram. Im gonna leave the 2nd slot opened till i get x2 2GB ram modules with same timings as the once on slot 1 and slot 3.
    So now i need to start overclocking and see what happends with the 4gb i have with same timings.
    If @profJim can help it will be good :)
    Thanks!

    Common sense would suggest that using 2 different memory module brands or models with identical SPD settings might or should provide better stability than using two modules with different SPD settings. Maybe it will, but the only way to know is to test for stability with your current settings. I suggest that you run the Prime95 Large FFT test for at least 3 - 6 hours to see if there are any worker errors. If even one worker thread has an error, this indicates that your system is not stable and the Prime95 test should be stopped. Letting this test run overnight for 8 hours or longer is an even better test.

    When you use two different memory modules with different programmed SPD settings the best chance for stability is to use the slower memory's SPD settings. With your original Patriot and A-Data modules, this means that the slower Patriot module's 6-6-6-18 SPD settings should be used because the Patriot memory has higher latency with it's 6-6-6-18 timings compared to the A-Data's lower latency 5-5-5-18 timings. It is possible that the slower Patriot module will be stable with 5-5-5-18 timings but they haven't tested the Patriot module at these tighter (faster) settings at or near 800MHz (2 x 400MHz) speeds.

    HWiNFO Version

    Upgrade to the latest version, so that there will be a new Page File Usage sensor reading near the top of the sensor list. If you are able to eventually run with 8GB of ram this should reduce swap file reads and writes to the page file and improve overall system performance a bit.

    Additional Overclocking

    I recommend that you increase FSB in 54MHz steps and run stability tests at each step. With your 9.0 X cpu multiplier, increasing CPU Host Frequency by 6MHz will increase the cpu speed by 54MHz (9.0 x 6) and memory speed by 12MHz (6 x 2.0) where 2.0 is the System Memory Multiplier that you are currently using.

    As you overclock higher into the mid- or high-end region, each step should require increasing CPU Vcore where each new step will require a greater core voltage increase than the previous step's core voltage increase. Each increase of one core voltage step in the bios should be 0.00625 volts higher (or lower), where 0.00625 is equal to 1/160th of a volt.

    Normally the best memory performance is using dimm slots 1 & 3 with identical memory modules. Running with 3 identical memory modules can be stable but this is not optimal. Check out Single- and Multichannel Memory Modes (Intel) and read the first half of the webpage that deals with Single Channel and Dual Channel setups.

    Any questions?

    Right now I'm ignoring memory benchmarks because the best memory performance will probably be with the highest cpu speeds. Tweaking memory performance is best done after you have reached the highest stable cpu speed.

    In the following two tests keep in mind that I'm using 8GB of high end DDR2 memory that has optimal memory settings and that the 3.502GHz and 3.825GHz configurations have passed extended stability tests. You don't need a high end memory kit to have good performance, but using higher end memory kits will provide you with additional overall performance.

    LGA 775 Cas4 800MHz vs Cas5 1066MHz DDR2 memory timings


    DDR2-800 memory is the same as PC2-6400 memory and higher end DDR2-1066 memory is the same as PC2-8500 memory. My higher end PC2-8500 memory is classified as PC2-6400 memory, for example in CPU-z, but the higher end kits have been binned and tested by the manufacturer to run at 800MHz with Cas4 timings and also at 1066MHz with Cas5 timings. With the vast majority of software applications and games there is little or no difference in real world performance between Cas4 800MHz and Cas5 1066MHz setups.

    There can be noticeable performance differences with some demanding applications such as music or video encoding applications or high end image editing programs.

    My Passmark memory Performance test results:

    Okay, first i did some overclocking and i have some information to provide. I increased CPU Host Frequency to 418 and vcore to 1.262 and windows booted up and i did some stability tests and they are positive. Then i increased CPU Host Frequency to 424 and leave vcore unchanged. It didn't boot and then i increased vcore once, and no success, i was increasing vcore till i hit 1.400V, and no luck. Then i decreased CPU Host Frequency to 423 and leave vcore 1.400V but no luck again, then kept decreasing the CPU Host Frequency till i hit a windows boot, when i got to 419 i saw the windows logo, then i quickly restarted the PC and got the vcore down to 1.262, and saved the settings and windows booted with a success, after that i did some tests and it was stable. I restarted the pc again and kept trying to get 420 FSB but no luck, and then i changed PCI Express Frequency from 100 to 101 and windows booted successfully, i did some tests and they were good, until i restarted my computer, bios boot loops 2 times or 3 not sure and OC reset and back to stock clock. What should i increase to get no boot loops after i restart my pc? Is there something i'm missing, and why 420 FSB wont work until i change pci-e freq to 101 and is this increase good or bad?

    Tried on higher FSB and higher voltage on vcore,termination,pll, and mch and no luck still getting boot bios loops.
