how was the stability on last setup? any priming?
hey bud, u might have a cpu that requires a little extra juice kinda like mine. there are some folks here with very low voltages and i just cannot seem to match that either.
first of all i would suggest 200x20 vs 190x21. the first seems to work better for me.

Thanks for the quick replies
I tried the 1.4 qpi no turbo as suggested by technut36 and it's booted at 20x190.....will keep trying to see where I can get to. Hadn't done any priming - I'm new to all this - but it was stable transcoding video files and playing games
@SteveRo - wish I was brave enough to take my CPU voltage to 1.55![]()

First time poster, thanks for having me. Yes, I have been following all the posts for the past few months, and its great to see lots of smart folks in one place.
Anywho, I had my i920 on a UD5 overclocked to 3.8 for a number of months and was running that for normal 24x7 operations, until I did an absolutely boneheaded move of using @BIOS to update the BIOS back at v4.stupid me.
Now, unless I leave the BIOS at "Optimized Defaults" I simply cannot get an overclock on my rig without my machine entering a reboot loop and defaulting itself automatically back to stock settings. I have been waiting for the magic BIOS update to cure my troubles... and have been using QFlash for every flash since (I'm now at 6a), but still to no avail. My rig simply wont accept any even minor bump to any setting without entering a reboot loop and resetting to default settings.
I just reseated my chip on the weekend just in case as previous posters described bent pins (I didn't have any), but reseating it didn't make any difference. Does anyone have any ideas? (aside from ever using @BIOS ever again)?
I'm almost happy - back to 21x190 with F6a although at higher qpi/vtt and Vcore voltages than F5g. 20x200 booted but wasn't stable.
Now, the only thing I need to figure out is why my 3x2Gb OCZ Gold memory will not run at 8x190. 6x multiplier and auto sets the voltage at 1.5 and timings at 8,8,8,22. It's supposed to be 8,8,8,24 1.65V at 1600MHz. I tried to set the voltages and timings manually but it doesn't want to know the 8x multiplier.
Anyone got any ideas to help me please?

Can you list your other settings, as Steve said, hard to imagine @bios did anything especially if you reflashed afterwards.
For example are you turning turbo off, if you were using F3 bios before going to F4, F6a etc, as F3 will need less vcore at same mhz because turbo is treated differently. And if not turning turbo off, you should need more vcore in all bioses other than F3, since F3 turbo only supports light loads in turbo versus F4 etc is true 21 multi.
But my guess is you are doing something different, or you are using auto and auto value may be different.
Thanks for the quick reply, I really cant figure else what it could have been. The only other system change is that I dropped in another harddrive since then, but I have a 650watt PSU and am only running a single 8800gtx, so I cant imagine that im out of power head room to push an overclock.
I will try to set it to a 6x memory multiplier manually to see if that makes any difference when I try to start pushing the settings. Thanks for the idea. I will let you know how it goes.
Thanks RGE. OK, when I get home from work tonight I will try to post all my configuration settings for an attempted minimal overclock. As mentioned though, it seems like even the most minor change in bios causes an instability problem. But I will try to put something together.
My other thought is, if someone has the patience to help me out, perhaps someone wouldn't mind putting together a settings list for their successful overclock (even a very minimal increase that SHOULD work for everyone - not dependant on "premium silicon") using 6a BIOS for me to try out and report back on... just an idea.

technut36 I Tried X16 and X17 also timings a 8,8,8,24 and 9,9,9,27 - no combination workedAny other ideas? I know I shoul dbe happy with the overclock I have got but it annoys me that my memory is running under it's rated speed
Oh and I haven't been called 'young' for many years![]()

2gb modules have been a problem for some folks when ocing.
You may need gobs of v.
For example my pi 2k memory - when I turn on xmp - it sets the qpi v to 1.555v!!!
Barring adding lots of voltage, send a complete list of your settings, v's, multi's, bclock, ... and lets see if anything looks unusual.
SteveRo, you saved my bacon!
So I rearranged my PSU rails, breaking up my 3 harddrives onto two seperate rails (2x500g, 1TB) and I also took out 6gb RAM of my 9 (removed 2gb modules). My first boot I just bumped up the chip to 3Gz with everything on Auto, and it failed out. But then pushed the voltages a small amount manually and perfect boot on second attempt at 3gz. Phew. I am back in business and can start tweaking upwards again.
I know what everyone is thinking, that 9GB is a bit ridiculous, but I do video editing with 1080p AVCHD files on Adobe CS4 and the memory makes my work purrr along very nicely. Now I just have to strike a happy balance with CPU clock and how much memory I will be able to support with my 650Watt Enermax Infinity.
But anyways, thanks SteveRo... a lot.
EDIT: Back up to 9Gb RAM and at 3.33. The RAM will limit my top-end of course, but I think the main issue was actually adding that other HardDrive which overloaded that one rail.
EDIT: Jumped the gun on the last edit. Weird, but i was trying for 3.60 and couldn't push it. Now it refuses to overclock altogether again. I didn't perform stress testing at 3.33 w 9GB, but was able to boot to Vista and post on this forum. Now nothing again. Perhaps its RAM. Will try to pull out some DIMMS again and go from there.
