Overclocking the D805..

[allstars]

Hi forum..

System is.. D805, Abit mobo, ddr2-667.

Currently clocked at 3400 mhz (fsb at 170) very stabile and at 30 degrees.

I´ve raised fsb slowly over some steps ending at 180 (3600 mhz) but then fighting my FSB:MEM ratio.. At 3400 mhz its perfect at 1:1, but anything above it changes to like
30:16 and 26:14. Why ??

If i can get it cpu running 3600 i´d prefer that.

Somehow the system stop raising my memory above the 170 FSB..

Btw.. at 3600 mhz temp is around 34 degrees.. Dont think there is any heat trouble at all.

Any chance its due to lack of power ? Nothing been changed in Vcore, nor Mem voltage..

Hit me with some suggestions..


Ty in advance.

When overclocking, you can't leave all of your settings on auto. Motherboard BIOS's aren't very good at overclocking. Reset your cpu to 3.4 Ghz (or even 2.66 Ghz), and write down all of your settings for everything, with everything set to Auto, except vcore. Then, go back and change everything to manual, with those same settings. That includes memory timings, PCI clock (speed), PCI-E clock, everything.

Then, when raising your overclock doesn't work, you'll be able to figure out what is keeping you from raising your OC. Of course, you really need to do a bit of reading/researching into what all overclocking entails.
