Highest safe fsb for my board

post #1 of 7
Thread Starter 
I have a asus m4a78t-e and currently have my 965be OC to 4.2ghz with a 16.5 mult and 255 fsb (stable)... For some reason this chip really likes being at 16.5... Any time I change the mult and lower the fsb I crash a few min into p95... I wanted to see if I can get to 4.3ghz but if only changing the fsb can make this possible, is 261-265 to high?

The settings I have now's temps are all fine with some room to spare.

as long as your voltages are with in safe limits, and your board is stable @ 261 - 265

Then it should be good to go

Very nice overlock you got their! Lookin good!

What vcore you pushing through your chip for 4.2?

The question is not how 'safe' an FSB is, but how high a value your motherboard can cope with until it becomes inevitably unstable. You may be hitting your 'FSB wall'.

When you lower the FSB and you say it crashes, this could be due to your RAM speed changing and becoming unstable. Check those over.

Ram speed is at 1700 and has 8-9-8-24 timings and checked out as stable on my mem tests
