    No you didn't confuse me - that's good info. The only reason I ran Prime for 10 minutes is to see if any glaring setup errors showed up and if temps were ok.
    So, I ran memtest -5 passes last night - no errors.
    I ran LinX this morning - @2048 - 5 runs and had no errors.

    EP45-UD3R - random bsod's  with 8 gb Patriot DDR2 - bios settings?-linx-png

    My core 2 temps (Real Temp): @ idle 31 & 40
    During test - they maxed @ 55 & 55

    Now, on to 12 hrs of Prime

    Question: If this passes - what next?
    My goal is to run as close to stock as possible: lowest MCH Core settings & lowest DRAM voltage @ 5-5-5-12. So, which should I start lowering first (or which is more important to run as low as possible)?

    I don't game, fold or run intensive graphics.

    Glad things are moving on.
    The ssd bit .,I had mine in the UD3 originally,and it worked ok,under vista I think, but its so long ago now,I cant comment much on it ,I may have added some posts to pj's threads,dunno.

    The memory: some rough pointers.
    Assumptions..allways a bad idea, but your vipers might be very similar to the gskill black PI.
    Test your memory as far as it will go..without any primes/burns,as far as it will go to boot into windows.
    Probably best to have the cpu on a lowish multiplier so you dont have to worry about upping the voltage to that too

    roughly..on 2.00D I think it was tho I probably tried 2.00B as well.
    800mhz 4-4-4-12 2x2 gb slots 1 and 3. 1.85v> 840mhz (420 fsb/cpu host frequency). 1.9-1.95v 840mhz-880mhz approx, 2.0v for 900mhz (450 fsb) That was/is the memorys cut off point for 4-4-4-12 timings and I mean a really sharp cut off point.
    Yes I got it to boot at quite a high mch v and with 2.3v running thru at 905 or 910 but it felt to me it was mainly a memory stick limit.
    Of course dropping to 5-5-5-15 it was all happy clocking again for awhile in the 450-490 fsb range.

    Static read value makes a big diff on bandwith and what you can achieve also ,depending on the memory latch letterA,B ,C<d.

    Then test the other set and see what it will do..on its own.

    I didnt run with 4 sticks of 2gb very long I preffered the high clock to the extra memory but my 2 sets were a lot different.

    What I ended up stable with was lower than the "crap" sets best 2 stick speed and a lot lower than "good" sets 2 stick results.
    But it was ok..no I cant remember now :)

    Other points..
    The board and memory was/is generally accepted to run best on a 1 to 1 or basis or using a 2.00 multiplier or for 800mhz speed having a fsb of 400.
    I think PJ already alluded to this above.

    The board is designed for 400mhz fsb as standard.(The 800mhz bus and 1333mhz memory thats stamoed on the box and all those big stickers!) The theory at the time was about 10% more capacity was built in.

    Getting above 430with a high clock cpu and hi speed memory was a wall for some ,with then another wall around 500fsb and nobody(with sane voltages) running above 500fsb.

    400mhz fsb is all your looking for tho I think to use a 9 or 9,5 multiplier.? and as PJ was saying. That is an ideal multiplier speed for your 800mhz memory.(the timings you get it to run at is another q.

    The 2.00B or 2.00D latch multiplier I think lsd did a test on those a long time ago and came up with a result something like the B was the best for 400fsb and a bit over.. I found the D better for holding a better tatic read,but in the end for me it came down to not trying anything that would go beyond the chipsets bandwidth in terms of memory.

    I found/find maxxmem2 usefull in that regard.If you can boot into windows,chances are it will run.It ony takes about 10 secs.
    If your results show copy,write or read showing over 10gb/s on our chipset/board the chances are you will need ahigh voltage to hold the clock.
    High voltage on what?
    Heh that depends if its just 400mhz fsb and your cpu is at max multiplier its probably too much performance being asked from the memory.. so more volts for memory control hub,more volts for memory or looser memory timings.

    Another thing to do..actually while you still have a relatively auto set bios.
    Increasing the mch..try putting in the number beside the mch ref box,instead of leaving it at auto.then increase the MCH v from standard.
    It should maintain the scaling.</d.

    edit:
    sorry hadnt seen the above post before I posted.
    Im sure PJ will get back to you but if youre happy as it is now, the voltages are so low ,hardly seems worth the effort of reducing them more.

    Thanks for the insight, kick - it's funny you mentioned lsd and the 2.00B latch multiplier - before I got started adding the additional 4gb, I pulled out some of my old papers I'd saved on OC'ing this board. His was the main one I'd saved with all the settings to reach 400 and beyond on this board and the E8400. that was what about 4-5 years ago? Anyway, this gives me a better understanding and should help (especially if I decide to push this beast around a little).

    So, I was running Prime since this morning and continued to use the pc. I was doing a number of different things (temps never got above 55) when all of a sudden it blue screened at about 8-9 hrs. I checked the minidump and it's got a bccode 3b - which points to the graphics card. So now I don't know if the memory settings failed or just the card ATI 4650. I was using the latest driver from HIS (the manufacturer) ver. 8.801 with a date of 11/25/10. There was an optional Windows update for the ATI display so I installed it - it's dated 4/19/11 ver 8.850. Now I'm going to run prime again. I think I'll take your advice though and first set the mch reference box to the number instead of auto and then Prime away. I'll let you know the results in the morning.
    by the way, here's the maxxmem2 screenshot.

    OK guys - ran for 12 hrs Prime95 - no problems, temps were all low. 2 questions
    1. As soon as I stopped Prime it BSOD. Is this normal? (same x03 code as before)
    2. Should I try lowering mch - or is it worth it?

    A BSOD at anytime is not normal.
    You haven't posted a screen-shot that shows memory settings or voltages.
    Without knowing your current MCH Core setting, we can't make any suggestions.

    The BSOD might be related to using the 2.00D memory multiplier when the CPU Host Frequency is less than 400MHz.
    2.00B or 2.00D can be used above 400MHz.
    Using the B memory strap usually allows Static tRead Value (aka tRD) to be 1 setting lower than using the D memory strap from 400 to about 475MHz.
    I've had no problems using the B strap above 400MHz, but some had stability problems and found the D strap to be more stable.
    The B memory multiplier should be used with your hardware when the CPU Host Frequency is between 300 - 399MHz.

    again and Pj

    A guess on your settings being the same as on the previous page..ie at 333mhz and using a slightly higher mch v?

    Anyway as PJ says shouldnt be any bsod at all.

    If you take the view that everything is sorted..ssd etc and gx too and its only a problem with 4 sticks of memory.

    I as you may have gathered from the old settings I posted am a big advocate of pedal to the metal,Imean I dont shy away from going to the max voltage quoted for components as long as things dont overheat in readings.Like 1.4v+ thru the mch,(and its still alive) :0

    ie I(when I post), PJ, Wazza.. and others still suggest maybe a v small increase in the voltage to the on chip memory controller even on sandy and ivy cpu's if there is a problem with unmatched memory sticks.

    Story: which you may even have seen,back in the day.

    Poster couldnt get his 4 sticks of memory to work reliably. I think they were matched pairs but not matched 4 sticks of the same model number.

    Lsdme suggested ,as you do, perhaps a slight mch v increase to help( I had to use very big ones at the upper end), ( the memory may have been of a type with its best profile stated as 2.1 or 2.2v so not much room for adjustment there).

    To cut it short, the poster tried mch v increases and didnt get anywhere.

    Next thing the original poster came back with a "nyah nyah.. you suck Lsdme,..look what I did..I dropped the mch v,(I forget to what like 1.06 or something) and fixed it myself!
    I dont know if he won the Nobel prize that year!! and the only reason I remember it, is we were saying/thinking, "wot a tool"

    Maybe it locked up the next day!,however you certainly wont burn anything out by trying..

    Its no harm as in PJ's sig to load and save optimised defaults once in awhile if you have been changing things off standard and then start again,some values for me used to stay changed especially with post failures,even if the red warning label didnt show when entering mit.

    If it was me Id still goand see what each pair of memory would do at 398/400/402 at what voltage and timings then go for something about 10% less than the worst that one pair gives for 4 sticks together,if you follow..like turn cpu down to 7 or 8 or whatever while your doing it.
    It isnt just because its fairly easy to doon simple multiples for the memory, but you would also find that because the fsb is at 400,the pc will perform better,even if the cpu speed is the same or the memory speed is the same as at 333 (with the same memory timings that is).

    Something along the lines of the 486 dx50 I suppose which had an actual 50 mhz board as opposed to the 25 and 33 mhz ones and for under $5k!

    Most of the 8GB DDR2 memory setups required MCH Core to be in the 1.24 - 1.30 range and sometimes higher. In many/most cases, G.Skill memory kits usually required MCH Core to be set to 1.05 or 0.95. Very few other memory kits required MCH Core to be lower than 1.20 with 8GB. Most of these systems were running with or near 1066MHz speeds with 5-5-5-15 timings with high quality memory, that is with ratings that were 4-4-4-12 at 800MHz and 5-5-5-15 at 1066MHz. Dram Voltage was usually set at or near the maximum voltage on the memory's sticker.

    If you don't want to overclock your cpu, your overall performance will be noticeably better with the following settings:
    cpu 425 x 7.0 = 2975MHz
    memory 425 x 2.00 = 850MHz with 5-5-5-12 timings
    Cpu Vcore and Dram Voltage might need a slight increase.
    Naturally you need to stress test each time you change bios settings.

    kick isn't always wrong, but he's never right (or something like that)
