    I don't have a TrUE, so I can't comment on how 2 fans would improve cooling.

    My own opinion on push/pull setups is that it's not worth it for me. You basically double the amount of noise for maybe 2-3c gain at best.

    You could always get two fans now, and if the difference isn't worth it for you for whatever reason, you can use it as a case fan.

    Actually, I am running 445 at 1.25625v, and 24 hr blend, prime stable. I just bumped the fsb to 450 just to show you 450+ should not be a problem. 1.2625v was a typo on my part. It primed at 450, blend test at 1.25625v for about 3 hrs but I needed my computer for something else, so I stopped it. Also, my goal is different from yours. I am trying to achieve 4ghz with the lowest voltage settings across the board. I will be lowering voltages for my MCH ICH and lastly Dram, as I think I have room to move for those parameters. I had a feeling you wouldn't be able to prime stable at 1.25625v with your setup based on what I had read on this thread prior to posting my template. My contention was to impress upon the need to loosen some of your advanced memory timings. My template was just to show you that 450+ should not exhibit boot up problems with your setup. It looks like the next step for you is to increasing the vcore. As I don't know what your temps are like, I can't tell you how much to increase your voltage settings for your cpu. Certainly Psycho101 has some good advice for you. As he pointed out, MCH/DRAM on auto might be a good idea as I noticed you have your setting at 0.87v which might be a bit low. Also, there is nothing wrong with auto settings for your A&B refs. As there are many ways of reaching one's oc'ing goals, I would probably bump vcore to 1.30v, 1.325, 1.35v. If successful, then ratchet down, to tweak final vcore. As others have mentioned, you just have to be methodical and systematic in your approach when trying to reach your targeted goal. The only reason, I am suggesting lower initial vcore increase than Psycho101 is suggesting is that I don't think your hsf is helping you as much as you wanted and that you have some high temps, so going easy on the vcore increase might be the approach for now before your new hsf arrives. Again, it is just my opinion and certainly may not be a superior approach to what Psycho is suggesting.

    All the best.

    Exactly, as I feel the same way. Most people probably have a rear case fan anyways, and if they have a top mount psu with a fan on its belly already, or a top case blowhole, why bother with the 2nd pull fan for such little gain, if any, at the cost of more noise and electricity.

    I say Fugetabadit.

    I agree about being cautious with vCore, especially until you get your TrUE.

    As I have always had my cooling in place before starting to over clock, I usually go for the slightly "brute force" method of setting maximum recommended vCore initially (1.3625v), then working my way downward when I've reached my goal. Currently, you may want to lower CPU multiplier a notch instead of raising vcore and increase FSB to see if you get stability. That does a nice job of taking CPU issues out of the equation. When you are stable, moving the CPU multi back up, plus a possible increase in vCore should get you stable at the higher speed.

    Bear in mind that it's common on many CPU's for there to be a point where all of a sudden, you need what seems a huge voltage increase to be able to procede. My Q8200 will do 3.22GHz on 1.2750v LLC disabled, but at my current 3.4GHz It needs 1.3500 with LLC on.

    This was however mostly with 65nm CPUs, and I have never seen so many high clocks on low voltages. It really is a testament to Intel's quality fabrication process. My 45nm Q8200 can do its stock 2.33GHz on just over 1v.

    BoombasticSloth raises a very good point. Monitor temperatures carefully, and be cautious with your voltages. When you have temps sorted, you can afford to be braver, but still careful.

    I used to do this method as well, but my girlfriends made me change my ways and I am a much better man for it .

    All excellent advice, cheers!

    The TrUE Black 120 will hopefully be installed at the weekend, until then I just use my 3.0GHz profile in the BIOS for most things.

    All installed!

    Just ran a quick IBT (5 passes, max stress) and the highest temperature it got to was 67deg C using 450x9 / 4.05GHz. With a lower speed than this last week using the old cooler I got to 85deg C on the same test.

    For some really strange reason a profile I had saved and working with the old cooler doesn't want to boot into windows but a faster profile with looser timings still boots ok, could this really be temperature related?

    Excellent results! Glad you'r happy with it!

    As for the strange profile thing, that seems wierd. You could try and eliminate any variables by maybe loading Optimised Defaults, then save and exit BIOS before re-entering to apply the misbehaving profile.

    I wouldn't say that reducing heat would cause instability, more the oposite.

    My one thought though: what cooler were you using before? Was it the Intel one? If so, as you know it's a top-down cooler, and will be blowing some air over your RAM, Motherboard voltage regulators and maybe northbridge to some extent. Installing the TrUE will stop this happening and may cause things to misbehave, especially if say Northbridge volts were a little high and it was getting too warm. Any change in weather can effect this too, strange as it sounds. Ambient temperature of the atmosphere can effect air cooling significantly.

    I think I sorted it, somehow my memory in that profile got changed to 4-4-4-12 from 5-4-4-12.
    Is 67deg C pretty good with IBT running and that amount of overclock? I was concerned about having the TrUE seated correctly...
