cegras Posted January 26, 2008 Posted January 26, 2008 With dividers on the RAM (and loose timings), the board hiccups above 275. (275 was OCCT stable) I will change the 'fsb' to just a bit over (say 277), and the board hangs just before it does the whole 'verifying DMI pool data' thing ('backing up CMOS' is what comes after), and then reboots. Why does it hang here, and are there any suggestions? Upping voltage didn't help it past this little hurdle. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted January 27, 2008 Posted January 27, 2008 So you're currently running your X2 3800 at 2.65ghz? That's not too shabby Anyway, if you want to post up all of your BIOS settings using the Socket939 OCDB template we can take a look at them and see if there is any other minor tweaking that can be done. Template is attached. Just replace the values already there, with the actual values from your BIOS. Share this post Link to post Share on other sites More sharing options...

As for other settings, if you really need em I'll reboot and copy them down, but I think I've got all the 'major' settings in there. I was just wondering why the computer would freeze on the 'verifying DMI pool data' or the step just before it? My max was 2.75 with ram on dividers, this mushkin kit tops out a 222. : ( Share this post Link to post Share on other sites More sharing options...

cegras Posted January 27, 2008 Posted January 27, 2008 wevsspot, thanks for the advice. Tested ON 275 is stable, however. I'm trying to keep OC'ing on CnQ because I like it idling at lower temps and using less power when I'm just browsing the net. I know it's stubborn and boorish, but could you bear with me on that ^^; from 110% - 113% doesn't help me past that step in the bios 'boot up' Share this post Link to post Share on other sites More sharing options...

red930 Posted January 27, 2008 Posted January 27, 2008 Maybe some mod should change the topic to AMD Athlon 3800+ X2 since it sounds like the post is about the upcoming Dual GPU from ATI or something. Maybe it's just me i don't know..... Share this post Link to post Share on other sites More sharing options...
wevsspot Posted January 28, 2008 Posted January 28, 2008 that may be something that make your OC crap out CnQ have to be disable if you overclock otherwise system hang can appear and limit your OC QFT It was always recommended to completely disable CnQ on the NF4 boards when overclocking. AMD and nVidia just never got it quite right on that chipset when users started manually messing around with voltages, multipliers, fsb etc. Share this post Link to post Share on other sites More sharing options...
cegras Posted January 28, 2008 Posted January 28, 2008 wevsspot; I've been running my settings with CnQ enabled, so I'm not sure what would make it unstable though. I'll try doing a suicide run with dividers, 280 FSB with CnQ off and the voltage settings recommended. Can you explain a little what those new ram tweakings will do? I have read through the memory part of the OC'ing guide and it says 4 Drive Strength is good for non-TCCD memory. Share this post Link to post Share on other sites More sharing options...
red930 Posted January 28, 2008 Posted January 28, 2008 Cool n Quiet is only good for people that are trying to consume power, not for overclockers. You don't want your cpu voltage to fluctuate period. Especially when you have it over the stock voltage. Not a good idea, listen to some of the members here.

I always had the best luck with a setting of 4 on Drive Strength too, but since you are wanting to squeeze every last bit OC out of your rig, it's time to start "playing with the values" one point here one point there kind of thing to see if we can get the absolute fine tuning right on the money. Thats another reason I recommended leaving some of the settings on auto. From there we will have to take it one setting at a time.
