    Default EP45-DS3R + 8GB RAM + Q6600 stability

    Hi, I have an EP45-DS3R with a: Q6600 G0 SLACR w/ VID 1.325 (high!), and 4x2GB of Patriot Viper PC6400 ram Newegg.com - Patriot Viper 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory . http://hardwarelogic.com/news/134/AR...008-01-23.html

    I am having trouble achieving a stable overclock. Memtest on the ram shows that it is fine after 5 passes. I get crashes running prime95 and games, however. Ive upped vcore as high as 1.6 before, but i still get crashes. I'm not sure what the problem is. Right now i am running at optimized defaults for stability.

    Here were my settings:

    I just tried HCI memtest that runs under windows. It detected some errors... which memtest should i trust?

    also lower this to 9 .. don't need 12 ... Static tRead Value

    (G)MCH Frequency Latch .. try set to 333 .. because that is what you running anyway.. auto some time does weird thing

    i sugest up your MCH little .. maybe to 1.26 .. and you probably can lower your vcore

    good luck

    Be sure you are using the latest Memtest86+ >>>
    Memtest86+ - Advanced Memory Diagnostic Tool

    Beta (Which will correctly pickup your timings and DDR type >>
    Index of /download/beta/211b6

    OK i cannot for the life of me overclock at all. I have lowered down to 333x9 but still nothing. Nothing I try will boot to windows except for loading back to optimized defaults + changing DRAM voltage to 2.1v. Everything else is auto right now. At these defaults and with most things on auto except for dram voltage, memtest86 goes through 5 passes fine and also prime95 shows the system is stable as well. Where should I start to see what the problem is?

    Please post for me the exact overclock full settings you are trying that fail and I will advise you some looser/better things to set to get going. Most of the time that is the problem, just getting it going then all can be lowered once you get going

    Usually i just get a reboot loop that reverts me to default settings. M.I.T. tells me that system has failed due to overclocking blah blah blah. thanks!

    Default Re: EP45-DS3R + 8GB RAM + Q6600 stability

    still does not boot... Reboot loop... i have even tried a 2x1GB set of ballistix. Using Easytune to overclock works, oddly.
