I have just purchased a Radeon 9700-have cracked the bios and O'Cd the Core up to 325(Its "correct" level"). My question is:- The memory on the 9700's is slower-(mine is infineon 3.3)-what would be a normal "safe O'c" for this?

I am a tad dissapointed as i got artifacts at 308(mem)-My old 9500 pro went up to 325\325(650) with no artifacts so........

I am currently running at 325\300-but want more, how much more is "safe". Currently getting 157003d marks though so im still "quite" pleased.

My calculator says the correct speed for 3.3ns ram is...303MHz! So, you get artifacts when overclocking to 308 because...it's overclocked past memory spec! Sorry.

Thanks for the info-what is the typical memory put on the Pros's?

I realize it runs at a standard 310-but i preusme it is generally memory capable of say 340-350?

9700 Pro BBA has 2.8ns memory, which should be stable at 357MHz according to my calculator.

I don't see why you would say that, the memory in the Pro is good for around 50MHz more than the non-pro, assuming the Pro uses the correct 2.8ns memory and the non-pro uses 3.3ns.

I was under the impression that the cards were exactly the same-except for the np being underclocked and a diff in memory speed(headroom) but not 50Mhz-I thought maybe 30Mhz.

Doh-thats what you get for not being thorough prior to purchase......

In retrospect i would have gone for the Pro.

Remember that most cards use underclocked memory for stability, and that card manufacturers sometimes reduce voltage to reduce heat, which can affect any overclock. In other words, we are discussing what clocks SHOULD be supported based on rated speed in nanoseconds, and REAL results can varry.

Like most of us i have managed to convince myself that 200 3dmarks will change my life,

Bearing in mind all considerations(i paidĀ£145 for the 9700np), im still well pleased.
