i get my 170 for sub RM500 and now the new 175 also for sub Rm600

4Ghz?

1.45V may yield you merely 2.8~ 2.9Ghz
if you lucky enuf, maybe 3Ghz but dunno about stability issue.
4Ghz for opty146 was insane, i think WR also below 4Ghz, maybe 3.5Ghz only.
anyway, try to oc, who knows how high you will get

Added on January 14, 2008, 1:48 amopty 170, what is the stepping for this opty that you have?

my last opty170 yield me 2.5Ghz@stock voltage running 24/7
max oc i attemp was at 2.8Ghz@1.45V , not trying higher cos
temp rise pretty high even when idle.

i must say this 10multi will do best at 2.5Ghz @stock Vcore.
you can try to let it run higher with better cooler

opty170 with 10X multi was the most easy opty to OC.

due to dual core architechtual, it was way too hot that u might try to cool it below 60C.
another thing is try to check your stepping for this opty170. some good stepping can go
3Ghz but mostly they will stop around 2.8Ghz, i had mine last time running the most at 2.9Ghz with air cooler.

TR 90C was a great choice, but try to use more powerfull fans, as it's full cooper, may need powerfull fan to
perform it's best.

another thing was ram divider. try to set as low as possible, while up the fsb of your system so that u can know
your opty's limit. then fro there you can start to compensate the best speed and timing.

happy oc.
