Little help pushing my Thuban

post #1 of 23
Thread Starter 
so i have been running at just over 4Ghz stable for a while now but i have been having a ton of problems getting a stable OC past that. Im wanting 4.2-4.5 range but i just cant seem to get a stable clock at that speed. here is a screenshot of my cpu-z. any suggestions and i dont want to drop my FSB any lower as to retain my 2133Mhz (native) speed for my ram. Also, power and heat arent a problem. thanks for any help:thumb:thumb.gif

Power and heat very well might become a problem with the voltages you'll probably need to get higher. 1.5v is the "max" voltage, but with enough cooling, you can get a bit higher. (I would not advise this on only a 120mm AIO rad)

And for the record, Ph IIs like lower timings more than higher speeds. If you could get it to like 1600 7-7-7 with the NB at 3Ghz, your Thuban would be a very happy chip.

have you used this guide?

http://www.overclock.net/t/777378/official-gappos-little-deneb-thuban-overclocking-guide-with-too-many-smileys

the amount of ram you have may be limiting your oc. what are the settings of your cpu/nb (freq and vcore)?

Reeeally...

But ya, dump all the volt/multi stuff on us, it'll help.

I upgraded from 16GB about a week ago from the same clock, and I'm not going to pump 1.6v down it with just an H100. tongue.gif

Plus mine is a 24/7 clock, not a suicide. wink.gif

EDIT: Oh hey, look at that.

man, that 970 is impressive. you are right that was a suicide run. the chip is only prime stable at 4.4GHz. i think the board is limiting it but not worth going am3+. besides, it is an office rig. btw, that run was on air.

4.2-4.5 seems a little ambitious.
Mine won't even prime stable at 4.1 with 1.55v, for reference.

Thanks. biggrin.gif

I can't quite hold 4.4 sadly. Not without another voltage bump and 1.55 is pushing it as it is.

And the H100 is just a NH-D14 in a different format. tongue.gif
