    Sounds like a good idea. If the same thing happens, ie instability within the sama timeframe, it's not RAM speed (probably).

    Maybe I was fortunate, but based on my experience, I have been able to rock 4ghz with 1.20v mch core and 4.25ghz with 1.22v mch core, both cases with 4 sticks of 2gb ram, which probably needs more mch core than just two sticks. I think I just happen to find a right combination of other critical settings for them to work. I always have been stingy with voltage because going green (well, at least to some extend), is always on the back of my mind so I always bias my settings accordingly. And with less voltage, there is less heat, so then I can use quieter fans. It all works out. Finding the sweet spot with the mch ref, cpu ref, and vtt relative to cpu vcore settings can not be over emphasized, and yeah, it can take time.

    I think I am with Grish on this one about the 2.00D strap. All other things being even, 2.00D is probably more doable than 2.40B strap.

    Well put.

    I've been giving power consumption more consideration than usual at the moment. Due to my financial circumstances I have had to move back in with my parents for the time being. Not an ideal situation, but my folks rock, and are very easy to get along with.

    As I'm a paying guest, I feel it's only right I cost them as little money as possible. Things like enabling SpeedStep amd even turning the PC off at the wall socket can all mount up when you're trying to minimise so called "vampire current" IE power used for no reason, sinisterly drained by greedy appliances. The sale of a few bits and bobs on eBay, and I'm now the proud owner of a cracking PSU. It's been awarded an 80 Plus Gold rating for the UK and a Silver for the US. Due to the higher supply voltage here in currently sunny England (230V), it pips the US 120V figures to the post by 1% or so. Only time will tell if it makes a difference, but either way, at least it's cutting carbon emissions if it's not saving a tangible amount of cash.

    Yeah, I hear ya, Psycho. My current financial situation is sucking right now. I used to be a high flyer with no financial qualms to worry about, but now, I have to be mindful of everything. I have had my eye on those new HX line from Corsair as well, particularly the 750 and the 850 version. They do look tasty, but I have to restrain myself.

    Morph, here is the template that I had used for the second box. It was just a setting that I slapped together, and probably isn't the most ideal, but it did 24 hr prime stable. Psycho had eluded in another thread that I probably could have lowered my mch ref lower, and he is right (as usual :0), but at that time it was just a combination I just slapped together before moving on to a higher oc target.

    Ok, first things first, thanks for trying to help.
    Psycho, what did you mean by increasing CPU multi? I'm doing 445x9, there's no higher multi for me.
    I'm absolutelly sure it's not my RAM, as i failed prime with both 2.00B and 2.00D anr/or 6-6-6-24.
    My last run last night resulted in a restart after about one hour of prime.

    LE: Ok, just to make sure it's not my RAM, I let orthos blend to run with my stable 3.6GHz/1066MHz RAM with 2.66C strap and tRead 7. Timings are way tighter than what i tryed for 4GHz, and voltages are pretty low. I was also watching a BR movie and using torrent at the same time.
    Here's a screen:

    Well, I've stopped Orthos after almost 8 hours with no errors. Didn't feel the need to go any further, as I've already done 24 hours no errors some time ago. I just needed to make sure again. So, it's not my RAM's fault. Guess I'm back to scratch.

    That shows your memory runs fine at memory frequency of 1066mhz on this board when using 400fsb, 400 strap and 3:4 divider or 1.333 system memory multi. Then when you went to 445 fsb, and used a 2.40B system memory multi, that is a different matter. Your bios may be handing out brain fart sandwiches with 2.40B SMM and it's associated strap. Hence you shouldn't discount using a different SMM even though it would mean a lower memory frequency when experimenting with other critical bios parameters like mch and cpu ref, vtt, vcore, and mch core, as a way of further eliminating the memory settings as the bottleneck. That is all I am saying. You may even want to manually set the DRAM Termination, Channel A&B Ref, and MCH/DRAM Ref to 50% of DRAM Voltage. You may have already found a sweet spot with those mch and cpu ref, etc, critical bios settings and may not even have know it, because the SMM was borked to begin with because it was full with all those tasty sandwiches that the bios was handing out.

    I will take it even further since you are wiling to start from scratch. While setting the cpu ref to auto, may work for a lot of people, it may not work for some. Clearly something is not working out on your system, so try manually setting your cpu ref. Sure, the cpu ref is supposed to be set correct when on auto, but maybe the bios is handing out second helpings of those wonderful sandwich on your system when set on auto. Personally, I would prefer to manual set the cpu ref -3 to +1 notches from what it scales to when your vtt is changed from 1.20v. Then try the range of mch ref settings (-3 to +2 notches from what it is scaled to when your vtt is changed from 1.20v) for each of those cpu ref settings. Of course you have to try all these combinations for each of the vtt options you try for each of the vcore settings. As you can see, the possibility of combinations increase like crazy and that is where the spreadsheet helps to narrow the multitudes of options. Leave vcore at it's current 1.375v, and mch core at 1.26v, and pll at 1.57v for now since you said that you seem to have made some strides at those settings for now.

    Once you find the sweet spot for mch and cpu ref and vtt combo, you can try reducing your vcore as I don't think all that heat is helping as it is spoiling those god forsaken sandwiches the bios has been handing out so plentifully. Then later you can try playing with mch core.

    Yeah, clear as mud.
    Good luck and All The Best.

    The test posted above was done with 400 MHZ FSB and a 2.66C multi and tRead of 7.These I found to be the most performant and most agressive settings.

    All of my OC attempts were done using either the 2.0D, 2.0B or 2.40B multi, as these are the only ones left that will take my RAM closest to 1066 which I know for a fact is stable. Also, tRead was set to 9, 10, and 12, with driving strength from 800 to OC-1200.

    Also, I have tryed manually setting MCH Reference and CPU Reference from 0.64 to 0.81, one at a time, with VTT set from 1.1V to 1.34V.

    MCH core was also set between 1.1V and 1.32V

    CPU PLL was also set between 1.5V and 1.61V.

    Each setting was done only one at a time.

    I did mean it when I said I'm trying this for about one and a half week, every day, almost all day long. I wouldn't have posted if I didn't run out of other ideas.

    Your RAM is indeed stable, however, as boombastic sloth said, one of the straps that gets your RAM to 1066 may not be stable. This isn't the RAM's fault it's the strap/multi. Think of it this way: your PC is a car, and the RAM is the engine. The strap is the gear box. Your engine could be more than capable of 250BHP and 150 MPH on a certain gearing ratio. You then strip the box and change some cogs to alter that ratio. Unbeknownst to you, a cog is defective and slips on its mounting, and it happens to be first gear too. Your powerful engine won't be able to put the power down, as the gear keeps slipping.

    Your approach so far sounds good. Methodical is the key. Don't forget however that settings effect each other, so for example changing MCH ref on its own and CPU ref on its own may not yield any results. Changing them both at the same time to different values may synergisticaly help things along.
