I'm having a major issue right now when I go to start my computer after leaving it shut off for a while it will go to power up and just sit there no post beep at all, just sits there powering up my computer. However when I shut off my power supply for a few seconds and turn it back on and start my computer it will power up just fine. Anyone have any clue what could be causing this? It's almost like something isn't initially getting power from the power supply but when I shutoff/turn on the PS gives something on my mobo the necessary power. Any ideas?
>should leave enabled or if I should disable them?
I don't think it matters either way. Personally, I overclock E6600 from 2.4 to 3.2 GHz, I turn Vanderpool off because I rarely need to use the Vetzfeebler, and I leave the Execute Bit checking on to protect against viruses and Windows bugs.
What do you mean you did your first OC successfully? Your pc didnt start properly, thats not successful. It probably reset the settings to default (assuming that mobo does that, I dont know) so thats why you could boot after shutting off the power.
hmm, well before I even attempted a overclock and built the computer initially I had a bad stick of ram and with both sticks in it would do the same exact thing, power up but not boot. I replaced the ram which did start up fine and then after my overclock (and ALMOST) everytime I start up my computer it won't start up after being shut off for a while. Any one know why?
I wonder if your RAM is truly defective, or if it just needs more voltage than the 1.8V specified by DDR2. Most high-quality RAM demands more voltage than the DDR2 spec nowadays, e.g. mine is 1.9-2.1. To boot up, either the RAM chip has to specify relaxed timings in its SPD, or the BIOS needs to override the SPD with its own settings. For example, my OCZ RAM chips are rated as 4-4-4-15 (and I even get them down to 4-4-4-12 with only 2.0V) but the SPD actually says to use 5-5-5-15. This is to help boot up at 1.8V I think.
I would try using the latest BIOS from ASUS. On their website, they have the AFUDOS tool for flashing the BIOS. That might help.
Sometimes another option is to boot up with some crappy RAM chip, then change settings, shutdown, and insert your real RAM.
I have updated to the latest bios before I started ovrclocking. Today though I messed with some of my bios settings left the memory voltage at 2.0v and tested it multiple times on a complete shut down and restart and I must have tweaked something right because it boots up normally again and is overclocked at 3.2ghz under full load both cpus never get above 54 degrees C at 1.288v and 1.322v idel. So I think i'm good now.
In some ways its bad that you just "tweaked something right" coz if the problem returns after you reset CMOS, you wont be able to fix it as easily as if you knew what to do. Maybe a bit of experimentation to find the problem, but for the moment have fun OCing.
