    Yeah a big THANKS to all here in the forums for helping me get this rig a rockin.Seems like the bios options multiply on each new gen of board lol.
    Iv'e been building/tweaking my own rigs for 10 years and the Forums are the first place I go to get the inside info.Thanks again.

    Update: I was trying to see if I could hit 4ghz with all 8gb of DDR2 800 in.

    Wasn't going to well so I relaxed the timings to 6-6-6-18 which is the SPD for those sticks.

    Went back to 2x2gb but left the timings and resulted in reboots etc.
    Went back to 5-5-5-15 and no probs.475x8.5

    Too bad you can't get the 8GB to work. It would probably take some ungodly high MCH voltage which would require active or water cooling. Plus more reference voltage fooling around. How does Vista 64 perform with 4GB?

    Vista runs fine with 4gb. I can get 8gigs up to DDR900 but not much more.
    Idid get this rig up to 3.8ghz with all 8gigs. So for me the choice(at least for now) is running 4.0+ with 4gb of ram or 3.6-3.8ghz with 8gigs.
    I really can't complain either way as these sticks do run beyond their rated speed and at 1.8v too. Iv'e always had good luck with OCZ memory.
    I guess the thing to do is get 2 sets of DDR1066 and go from there.

    So close yet far away with running 8gb at 475mhz.Iv'e taken vMCH to 1.34 Not sure what the safe limit would be with the stock heatpipe cooler.
    I think I read somewhere that 1.4 is about tops. I think that vMCH is going to be the main issue.

    If you can somehow rig a fan blowing on the northbridge it would help. I have seen the Antec spotcool mentioned, or just rigging something with cable ties. Also, some are removing the Gigabyte nameplate on the top of the heatsink because it restricts airflow to the fins.

    Hi gang, this is my first post. I have been trying to get something to work on my ud3p. I was able to get my q9550 up to 3.6 on all stock voltages set manually. 3.7 starts beeping at me running linpack. I have tried messing with the voltages but to no success. I am going to try one of the first templates and go from there. I would like to be able to hit 4ghz and run it 24/7 for folding.

    I love this combo on my new rig.

    I have to say though I think you guys could push the performance envelope a bit further. I know the myth about VTT voltages being to high and possibly frying the CPU, but honestly it's been debunked..

    If you want more proof please read this post http://www.overclock.net/intel-cpus/...-stable-7.html from this forum, ( I suggest reading from the 1st page to the end, but this page towards the bottom is pretty much all you need under 45nm max safe voltage)and do your homework there are PLENTY more.

    Everyone has their own idea of what's safe, and to each his own.

    I just want to let you all know these CPU's can EASILY hit 500 FSB with correct voltage inputs, and NOt just the E0 version I have a C1..

    Anyone interested in the settings required let me know...

    CPU actual voltages according to ET6 which we all should know by now the board undervolts quite a bit.. Temps are at IDLE pictured the temp at full load never gets above 55c...
