Thanks for the reply.... I figure there was some vdroop to a certain degree. I got a q9550 sent to me in canada im trying to push the extra mile.. my M2F will post only up to 485 then after that I have to mess with GTL's and Shew and still 500fsb is very unstable for a prime run. thinking about getting one of these to too up my overclock.Quote:

But if its not orthos stable isnt it then, by definition, liable to cause errors at any time? i.e unstable and imho not reliably capable of performing daily functions such as loading tf2 maps? I would just stick with highest stable settings so i could enjoy my pc error free.Quote:

Hey guys - trying to gain that last little bit of stability on my setup....the settings i have now can intel burn test, and ran prime blend for almost 10hrs before i got an error. So i am close but not 100% yet. Any suggestions would be really helpful!!

Try more CPU term.
Thats what i dont understand - ive read the gtl ref stuff and I am still confused on how to set it up properly. If i up my cpu term then my cpu ref and mch ref should be changed as well...?

Here is a cheat sheet thanks to radaja, that helped me when I was first really messing with my setup.

but how can ... ?? you say? What can be ... Now I put everything to default and see if I have the same problems ... acnhe may be a software problem??
thanks
Sounds like you have not stressed long enough. Run small ftt's for 12 hours, if it fails, it's most likely vcore or Term. Run blend for 12 hours, if it fails, it's most likely MCH or ram.Quote:

So you want to start in the middle at the .836 and see if it's stable or not. If it isn't then hit the value to the left or right of that one and see if it's stable and so on.. There is no given value that we can tell you that your, motherboard will be happy with you have to feel out those values and see which one your, motherboard likes..
I would say what ever your CPU is happy with , go with as long as it isn't above say 1.35.. you can go higher but people get scared after a certain amount so I would think 1.35 should be safe.. Mine is set to 1.40 or .42 and it's fine and has been for awhile....
Mine won't run the speeds I'm at now without that voltage on the vtt, every CPU and chipset and any chip made is different a little..
Depends on what revision you have. I have 1.1 and I liked the F9 alot, but I'm using F10e right now.Quote:

I tell you I am using the new F10 officer and seems fine ... it locks;Quote:

are at 471 x 9 ... I can not set the strap to 266 ... is my problem? capiita or to everyone? I raise quaclhe voltage?
thanks
F10 does not lock in, just F10e.Quote:

I've currently got a dfi lt x48 board that is dieing and looking for something new. I was able to get the chip to 3.6 easy on that board with only bumping up the fsb to 400 and vcore slightly to 1.26. Getting much further on that board was about impossible and I ended up settling for 3.6 for stability. After reading the reviews for the ep45-ud3p, I am seriously considerring this board as a replacement. My goal, for now, would be to run the chip at 4.0 (400x10) on air for 24/7 use (eventually more when I get closer to upgrade time). Is this an easily accomplished goal for this mb and cpu combo? I also have 8gb of ddr2 at 1066 (5,5,5,15) running smooth on my current setup (long story short, ended up with an extra 4gb, so threw them in way after I was working on the OC for this setup). Is this board picky about memory type? Any help or thoughts appreciated. Thanks.
The QX9650 doesn't clock as well as the Q9650. and i cant imagine that the dfi doesn't do 400FSB (as you say you want to run 400x10). nearly every bord including the G31 and G33 will clock to 400FSB....Quote:

...scratching my teeth on P45 DK T2RS+ lol (maybe you could help me MrDucky?) I think you missed something in the bios Deviant1 ;)
What I think about the UD3 : the best board to go both 24/7 or benching rig
...easiest clocker I had with great reactions ...always reboot after fail !! no need to reset bios or even cut off the PSU.
Deviders work fine on DDR2 ones to push ram frequencies :)
But a bit dissapointed about how the FSB scales : stuck @580 (stable) --> 610 max with lot of pain xD
Euh! mine is dead now 'cus of bad insulation under SS -_-
You have to change more than just vcore when raising FSB. That's why you only got 3.6.Quote:

sorry guys, i was probably trying to keep my post above a bit short while getting in the details. As for the DFI, I had it at 400 fsb. I was running 400x9 at 1.26 (stock setting was 1.24) for over a year. I definitely tried leaving it at 400 and change the multiplier to 10 while raising the vcore, nb and slight bump in sb. When the board was new, I was able to get it to boot into windows and run at 400x10, but couldnt keep it stable on prime (also tried many other combinations to get speed up, unsuccessfully). I definitely read up on and changed many of the settings on the board, I just didnt go into depth explaining that on the first post. The board has been constantly deteorating and I can only keep it, currently, at 333x9 (stock) to keep it running. I have tried a thousand variations in the last month trying to get this thing stable at other settings. I dropped the fsb and multiplier to a basic setting and worked my way up. anything over 333 and it becomes a wreck. So anyway, this board was one of three refurbs that DFI has supplied me with and I'm tired of it. I would really like a decent board that I can use my qx9650 to some of its potential since i have it. Nothing too wrong with 3.6, but would enjoy playing with it at 4.0 and then wreaking havoc on the chip before I upgrade in a few years. I was just checking to see if 4.0 is pretty easy to obtain and run 24/7 with this board (and then to have some fun with in a year or two). Although I'm not looking to bench, i use the crap out of it for gaming, a couple of the games more cpu intensive than gpu. Running a gtx 280 currently and plan on getting the 5970 in a few months (provided my cpu isn't the bottleneck, then might get 5870). Thanks again for any advice.
:confused: it might need more vcore but mine did 500FSB pretty easy on air... and 4Ghz at 1.21coreQuote:
