As far as I can tell, leaving your HT-link at or close to 1800MHz is probably your best idea, as changing it doesn't seem to affect OC's much. And I wouldn't worry about your NB clock too much at first, but we've seen performance gains from OCing your NB... I just wouldn't sacrifice CPU clock for NB clock. If it should help for stability to OC the NB, then by all means do it (has anyone had an OC on the NB make a CPU OC more stable???), but otherwise I would wait to do it until you've reached a max CPU OC.

i would suggest for you to keep them around 1800. and as the REF clock increases you may have to drop the NB and HT multipliers to keep them around 1800.

my ref clock is at 265 and im using a multi of 7 on my HT and NB. 7x265=1855
ummmm. stuff

From the chip that I have played with the higher the NB clock the harder it is to make stable at higher cpu clocks. Also the NB gives similiar if not better performance than a higher clocked cpu (within 100-200mhz or so).

Ok, much appreciated! I just made a "what we've learned" addition at the end of the 1st post, so I'll update that again with this info (from both of you above).

If anyone sees anything else I wrote in that new section that is not correct, or seems contrary to your OC experience with this chip, please let me know!

EDIT: just updated the NB clock section of that.

i just put a desk fan next to my tower with the side off and my Temps dropped ~5-8 degrees C. my crossfire setup is heating up my phenom aftermarket cooling here i come.
maybe i should just sell my 4850s and get a 4870X2. but i need a GFX card the exhausts the hot air outside of my case.
with the desk fan i idle @ 35-36C without it i idle from 40-42C

Stupid dang chip... I had it at 1.66V, load temp of 60C, and it still wouldn't boot into Windows at 270 x 14...



I may install 32-bit OCNix on a thumb drive just to do this...
