    I did not think anything about you being a idiot! At All, simply asked to be sure if maybe you had switched ram or was borrowing some to test with.

    I did not think anything like that, just wanted to be sure as it kinda confused me how you said both

    I have not tested any Corsair in P45, but have not seen so many issues with it as in P35. So you may be fine

    Try this for 3Ghz to see if a overclock is any better since you did plan to do so >>>>

    Success! We have post without errors with the following settings...

    Now, whether these setting prove to be stable, is not yet determined. I'm running memtest86+ now to make sure I don't get any errors I only have the stock cooler on the CPU so I'll keep and eye on temps there.

    What settings do you recommend I alter if I run into stability problems? Back down the CPU frequency a bit?

    Well, if memetest has errors you would need to adjust some ram settings. If orthos or prime fails you would need to adjust CPU voltages a bit.

    So, you need to see if you do have errors, and which before I could advise.

    Nice to see you got going, I thought a overclock would be helpful. Not sure why but lately I have seen alot of "Stock" issues for sure

    How is load temps (Core temps) at that freq with the stock cooler

    Hey guys, here's my 3 cents. I have the same mobo and exact ram, but i have 4 megs so 4 dimms to swap around. I too questioned the ram when i got the board initially because of the adde3d complexity in tyhe bios pertaining to the memory timings. this board defininately allows much much more freedom to adjust every aspect of how the northbridge interfaces with the ram chips than any I( have had in recent days. I just switched from an Abit ip35pro which was easy as hell to overclock but had only about 25% of the available settings.
    BTW I have an e6420 that is a 1066 fsb chip runningm at 2.13 stock (8x266) 6, 7, 8 avail multipliers. Prior to the dominator ram i had some 4GB's of OCZ Reaper 8500 ram and ran it on 2 different Asus P5ks (both were wasted within 3 weeks of pickup) then I got the Abit as a replacement. The reapers would push over 1250 at 2.3v no problem, but I went through 3 sets of it in 4 months so i demanded my retailer exchange it for the corsair. In my opinion the corsair is solid ram. but the posted specs of 1066 at 2.2 5-5-5-15 c1 or c2 (luck) is about where they are going to perform. They are rock solid at the recomended settings but don't have much headroom i9n the frequency department to move up. Corsair did a 'good job' of speed binning the micron d9 chips and found the limits of the individual modules without much headroom.
    I recomend you get the newest EVEREST v4.60 which covers p45 and will diosplay EVERY possible setting for ram the is on the chipset tab. Stuff that even the f10 bios does not yet allow tinkering with.
    SO I HAVE A POINT HERE afterall. To get to it the reason you were having the failures was specifically because of the a,b,c,d strap settings the board uses when setting up the memory speeds. Instead of giving us a list of ratios like almost all other boards we choose a base frequency (which is the strap and is designated by the letter following the multiplier a=266,b=333,c=200,d=400) This is further confused by the 1066 you see on the left while selecting the bios settings. thats the number that the system is CURRENTLY running at, aka the speed its working at while youre in the bios and working. It will change after a save and reboot, but once the overclock fails it reverts to 1066 since this is the speed programmed into the modules. So it seems every time you are in the bios that the ram speed is going to be 1066 even after you have changed the base strap and then the multiplier, and finally reflects whatever alterations to the fsb you have made to jack up the processor.
    Alll in all it makes for things to get confusing and unless you have some good software to show the REAL settings once you've got windows up you'll never know because the gigabyte tuner does not really show much info at all.

    The other program to use is MEMSET.EXE find version 3.5. It will let you see all the data preprogrammed into the modules (there are 3 sets of settings 270,400,533mhz) first2 are jedec and 3rd is epp which is what the system board will default to. Then memset will allow you to change most of the timings settings while you are up and running, even some not in the bios. And you can even have different values for channel a vs b if all 4 sticks are not identical. great program. You'll have to rely on the gigabyte soft to do the frequency changes though and it's flakey in my opinion. I sort of think that the bios release (f10) is a bit unstable on top of that too so try and upgrade when you get the chance. back to the point.
    you were having no boot conditions because of 2 things (no offense to the other fella that was helping out) but the 4.0 multipliers are just not going to work unless you drop the strap to 200mhz or 266mhz and leave the stock multiplier and fsb settings for the cpu. picking 333 or 400 i have found won't boot regardless of the ram multiplier. don't forget that i have a 1066 fsb cpu though. if yours is 1333 then you might have luck with the 333 strap with3.00x I know that using 266x4 for 1066 was half of one of his suggestions. To his credit you will find a major difference in the driving strength profile setting he mentioned. This setting adjusts a number of unseen timings that have a huge impact on performance level. The lower the # here the tighter and thus much faster the system runs. I find that if I leave voltage atstock values (auto) and select 800 instead of 1066 driving profile I drop latency 75.x to 63.x while my bandwidth increases about 12-15%. This is with a stock cpu setting using the ram at 1066 5-5-5-15 and setting the rest manually to the settings you can read out of the ram sticks with memset or everest (4,4,8,56,4, cr2) (this is the order top down on the adv timings page) to be thorough (tRRD,tWTR,tWR,tRFC,tRTP,CRate)
    After those you have the channel A and B sub menus for timing and driving charachteristics. The static read is 6 running at 1066 from the SPD chip. leave the phase adjustments all 4 to auto for now and then input 8,8,7,9 for tRTR, tRTW, tWTR, tWTW. These are the programmed values but you can only see half the same /different rank #'s (if you dont know, these settings are the delays between switching operations from wr2rd rd2wr etc... These numbers are for when the mem controller needs to change operations within the current (i.e. already activated) Row (or Bank or Rank if you prefer. synonymous. not to be confused with cell or column as in CAS latency)[SAME] But there are different numbers if the change will make the new operation begin in a different Row/Bank because the new one needs to first be activated(e.g. the next sequential, or just some other random place the needed data is) [DIFFERENT] duh...
    Thus the same/different designations. The ones you input are the longer DIFFERENT values, and you will find that the same values are half+/-1 the different values. The exception being the read to write tRTW which has just one value since it already incorporates an additional step due to the command structure of the MCH/chip interface. 8 in this case.
    Point being the Driving Strength Profile make a big difference. you Will have to increase it to get any stability once you start cranking up the fsb. Start at 1066 and then move to 1200 once you hit a wall.

    And the single biggest setting that impacts performance is not available in the bios. its the "performance level" setting that came in with the 3 series chipsets i think. (965maybe) memset will give you access to this super critical adjustment. I'm not 100% on everything that it alters so I won't fill your brain up with only half an answer. Asus boards have access in the bios. I believe on our boards that it is altered with a number of other settings in the drive Str Pro. lower number are more performance less stability.
    MEMSET IS HERE Memset v3.5 Final & 3.5.9 Beta - tweaking Intel chipset memory timings
    EVEREST 4.60 Lavalys - Comprehensive IT Security and Management
    I recomend registering or whatever so you can access all the info. The bechmarks are quick and test mem latency and read write copy speeds as well as some for the cpu. for over clocking it provides near instant answers about what your alterations are doing. better than just running super pi to see if its faster cuz it gives you a big group of similar machines to compare your results to. Also has a solid Stability program that taxes your system and monitors the voltages and tems etc... and gives a stat rundown if you want it. Great for identifying where you need to edge up the voltage because of droop which is sort of prominent with this board, but it appears to be constant.i.e. it's always.0x below the set # instead of changing under load. for those interested i have an ocz 600, 8800gtx, x-fi plat music,2 raptor 74gb raid 0 OS and 2 WD500aakks non raid for storage. ASUS DRW-1814BLT dvdrw 4gb dominator 8500c5 core2 duo 6420 that I run at 2.8 most of the time, but I fidgit with it a bit. Custom watercooler sys DD8800 waterblock ddnorth bridge block thermaltake sb block and a cust machined cpu block that is very similar to oczs but I cut a diamond pattern rather than one of triangle as they did. oh yeah and a real floppy drive (I'm old school)
    hope any of this is helpful.

    Performance Level in Memset is Static tRead Value (tRD) in P35 and P45 BIOS's, just so you know.

    Long list of good info you posted for sure!
