fsb/htt problem

[KillerMCB]

Hi! This is my first post here, and I just wanna have some answers to some questions.

 

Right now, I am running my system at 290fsb/htt. It is very stable at that state.

My problem is, I can't reach 300. My previous board was an AsRock 939-dual sata2, and it flawlessly runs at 300fsb/htt.

 

My problem now with my nf4 ultra infinity, is that whenever I set my fsb/htt to 300, the nvidia raid screen appears at startup, even if raid is disabled, and I don't have a raid setup.

Did you raise voltage on chipset and LDT? Might help you out on that one.

 

I can't get my board to work "correctly" above 310MHz, which normally shouldn't be too much for these kinds of boards (I've seen scores of 350MHz+ more than once).

For me loosening max async latency and read preamble did help a lot to gain stability over 300 HTT.

unfortunately, this board has no LDT voltage setting. I increased the chipset voltage too, but still no go. What puzzles me is why does the raid screen show up.

[KillerMCB]

still no go.

I finally got it!!!

 

The problem was weird though. Whenever the ram divider is set to 133, it happens. I tried using the 133 divider, because I just wanted my ram to run at approx 200mhz. I just stuck to the 150 divider instead just to reach 300fsb/htt.
