ok, one thing to make sure is the fsb vtt voltage, make sure it stays at 1.5, anything lower causes instability.

What are your settings?
A simple overclock, still toying with everything. Check out the temps at idle in 25C ambient

Sent an email to EVGA so heres hoping they will have mercy and replace the mobo. I also mentioned the BSOD I was having:)
they are very good at rma, besides, this mobo has a lifetime warranty.
No reply as yet but I have also made a post on the EVGA forums highlighting this possible solution/answer. I have tried this quad in a 590 chipset and it dosn't have the FSB problem the 570 chipset does so it appears there maybe a link between the chipset revisions - anyone else managing decent FSB with the 570 chipset?
Some have the 570 some have the 590 - hence why some may be having problems and others not. Why a SB should affect the FSB I have no idea but I can't see any other reason as on dualcore I could exceed 500fsb easily and it was stable (500x8) - no such luck with this quad tho - its either stable or wont boot, no inbetween. Usually prime starts to get flaky once you are hitting the cpu limit but for it to go from stable to no boot with a 1mhz increase is bizarre.
My last 6 boards have been 570 (3 rma and 3 from the egg). Able to do 460+ fsb on quad G0's and 500 fsb on c2d. I've been wanting a 590 to play around with since i'm now so familiar with the 570. I think i remember my last 590 doin very well as far as fsb goes. Like i mentioned earlier though, 2 out of the 4 go's i had i couldn't even get stable at 3200 mhz, so don't always assume its the board, not all go's clock well.
590 SB here and I cant boot past 447 FSB on my board. No way, no how...
Here's what a G0 can do with an Ultima 90 and a new EVGA A1 680i, and I'm just getting started :D
I'm still working on pulling vcore out, my vdroop is .01v.
Please people, take notice of my voltages and stop trying to burn up your boards! Only thing I changed was Vcore and Mem. All other are on auto, which work all the way up to 1780FSB, so if you're under that, don't bother upping them.

Gawd I hate these boards. Upgrading my friend's A1 to a Q6600 was the worst PC experience of my life.
Weird, the board seems as stable and as hot at 400x8 as it does 400x9. I wonder if it has a NB cooling issue?
*shrug* i love these boards. I hate the p5n32-E SLI, but I sold it and went for the EVGA 680i. 4.0ghz benchable on my q6600, 3.8ghz daily use. shrug.
I'm having freezing problems which I cant seem to nail down, theyve been plaguing since I built this system a month ago..
watching xvid (7-29-07 ffdshow) while running prime95 was my stability test, prime can run forever, but for some reason Xvid decoding causes my system to freeze.. first the video, then the audio a second later, at seemingly random intervals (5-60min).. Its a really strange crash since there is no bsod or reboot, HDD light is lit which makes me suspect sata drivers are the cause.
Ive tried ultra loose memory timings, different voltages for everything (low-high) different fsb 380-450 with 7,8,9x from 3.2-3.7ghz.. they all have the same result.
never locked up in a game once... but xvid kills it.
Ultimately only stable below 3ghz, even though this cpu can prime fine up to 3.6 :/
can anyone help? :confused:
My 680i 3 first memroy slots are kabot so I'm on 1 gig in 4 slot & just started Orthos.:shocked:
Is that with the pencil mod for the vDroop ?
I may have figured out a workaround.. :)
installed ffdshow_beta1_20061211_clsid, when it asks what codecs to decode I unchecked Divx, Xvid and mp3.
http://sourceforge.net/project/showf...ease_id=469134
then installed http://www.divx.com/divx/windows/download/index.php for the Divx and Xvid decoding.
been testing stable over 4 hours, fingers crossed ;)
