    Well I for sure don't know how to spoof a "Load Optimized Defaults" so no worry there :) I have had to re-do my RAID before and while it's not difficult to set up again, it's an un-necessary step that gets in the way of testing IMO.

    I'm not necessarily new or just starting to overclock but my experience is kind of limited. Before the quad I had a E6600 which I ran at 3.2GHz without much problem and before that, I ran the E6600 on a ASUS P5NSLI which allowed an almost pointless overclock and got hot enough to cook an egg so I never did much on it. This is my first REAL motherboard with all of these settings and now that I have a 45nm CPU, I can do quite a lot.

    Basically, here's what I want to do:
    3.2GHz or more on the CPU (more would be better for down the road but I used 3.37GHz for a while and didn't NEED it but on the same hand, I wouldn't turn down 3.8GHz).
    Probably no more than 1110MHz on the RAM as it threw a Memtest error at 1128MHz.
    Tight memory timings.
    Volts that won't risk longevity of the components, I don't know how long I'll keep them.
    For the FSB, I'm sure I don't need to tell you that more would be better :) I don't really want to go less than 450 since my first template was that and it seemingly ran fine.

    I'm not entirely sure how much of a difference the RAM and northbridge fans made but I remember one time feeling the heatspreaders of the RAM and they were pretty warm and I recently added the northbridge fan since I had a spare one and was in there cleaning and re-building it anyway. I think I saw the G.Skill one when I researched before making one but when I looked at them there was either reliablity issues or something and mine was cheap with spare ball bearing fans. Also, all 3 fans run off of the PSU dedicated fan line which runs them at around 7v and increases voltage as the PSU heats up. For the summer I may switch them over to 12v just for that extra bit of cooling.

    I did read the thread similar to mine:
    http://forums.tweaktown.com/f69/q955...e-my-oc-38965/
    I tried modifiying his recent template for a lower CPU speed in hopes of less volts but I failed

    Anyway, thanks for willing to work with me

    Well it's just two setting values that allow us to tell which you are using, and sometimes users find this by reading other posts and then just change those and say they loaded optimized. Then only tell us otherwise 2-3 pages later after almost giving up.

    You don't have to redo your RAID, you just have to set the settings again (2 of them) is all. Are you unsure about that or what did you mean? Flashing your BIOS or loading optimized wont mess up your array unless you forget to set RAID again the BIOS, which is simple so not sure what you meant by re-doing it.

    OK, well for now then lets do 3.6Ghz but you may need to have your memory at 900 this way, due to your memory may not work right at 450 FSB x B memory multi's for a higher value and 2.66D is too much. 8GB of memory is not going to be stable much over 1000Mhz anyway, if even that.

    If you want something else let me know and I will advise, there is just so many ways to go about things and I'm not there so it's hard to tell what will and will not work.

    Thanks :D I'll test that tomorrow since I don't want to be up too late tonight.

    I hate to ask since there is SO much controversy but what would your opinion be:
    900MHz with 5-4-4-12 or 1080 and 5-5-5-12?
    I mean, sure I could test using Everest and get exact MB/s readings but I would have to get everything stable and then do it. If it were you, which would you aim for? I read that Intel chipsets don't necessarily like a 1:1 ratio and prefer others. With that said, I'm pretty certain that when I had 1080 5-5-5-12 that it was stable.

    You would need to test and compare really. Depends on the tRD you end up getting to work and which multi/strap you use for each.

    Really though I doubt at either of those speeds tRCD and tRP are going to make that much of a difference. Now if you could get CAS 4 to work at 900 it would likely win, like maybe 445-12 or 455-12, but you never know without testing each way what would be best.

    In the real world you would not notice either way, only in benchmarks.

    Intel is fine with 1:1, actually it's the easiest to use. I'd probably go with 4GB of memory! HAHA, you asked! Then you could run 1100+ probably, but then you would still wonder if 1100+ would beat out 900 @ 444-12

    Ha :) I went with 8GB because there are times that my usage goes over 4GB and I bought it back when DDR2 prices were low, since then the RAM I bought has doubled in price. I did try 900MHz 4-4-4-12 once and the motherboard beeped up a storm and restarted a few times. I'm guessing it didn't like it 900MHz with 4-5-5-12 or so I didn't try so that might be interesting. I'm not benchmark crazy, just looking to squeeze the most out of it. Anyway, fun day of overclocking ahead tomorrow.

    Ahh well if you need it then, you need it.

    444-12 eh. Was it 23 multiple fast beeps? If so then you may be able to run that, just correct the cause. Many fast beeps (if that is what it was) is almost always tRD set to low by the user or Auto. Try it again but this time set your own tRD and pick a higher value at first to ensure you can boot.

    Well good luck with the testing! I am about to jet for the night. See ya tomorrow

    I knew I should have counted the beeps and remembered it to look up later. But, yea it was something like that. I thought the darn thing was going to explode or something it was definitely unlike a typical long beep followed by a couple short one. And yea, all other timings were on auto at the time. 8GB at 900MHz 4-4-4-12 is sounding mighty good right now, you're getting me all excited lol. Take it easy, I'm sure tomorrow I'll have many findings.

    Well there is only one beep like that, so no need to count the beeps

    If it was multiple short fast beeps then this was that was it. It is the only one that scares people, so has to be it

    Good luck with the testing, I'll see ya tonight

    Well 900MHz 4-4-4-12 w/ 8 tRRD and 2.1v POST'ed but I'm 9% through test #7 on Memtest and there's over 6500 errors Probably won't work too good. Unless you have some kind of voodoo, I'll probably shoot for 1080MHz.

    It passed test 7 of Memtest and passed the hour long test of OCCT Linpack and temps didn't go over 70c on any core or the northbridge with all fans on low. I'm bumping it up to 455MHz FSB with everything else the same and I'll see how that goes. Then maybe 460 and I think that will be the limit of my RAM. Any suggestions on voltages or timings tightening?
