Abit IP35E question (OC)

[chiew]

hi all, just a few quick questions.

i have an abit ip35-e mobo, and when it's paired with my e4300, i'm pretty sure its my cpu that is the limiting factor in OCing. i was just wondering what kind of upper FSB limit i should see with another cpu. the highest my cpu allows is 9x350=3.15ghz, so 350x4=1400mhz fsb. i was wondering a couple things:

if ip35-e can take fsb of 1600mhz or higher (assuming it is paired with a different chip than the e4300)
and if it can take 45nm chips

thx in advance

IP35-E should be able to do 500fsb if everything else is also upto it.
& yes, there are BIOS with 45nm support.

You are setting your memory to 1:1, right? One of two things may be happening.

1) You may be hitting the limits of your CPU.

2) You may be hitting a FSB strap issue, or memory limitation or something else.

For 1) there's nothing that can be done. All CPUs clock differently. I had three E2140 chips and there was about a 300MHz range for maximum overclocks. I also had three Opteron 144 chips BITD and the range was closer to 900MHz. :Q

For 2) you can test by lowering the multiplier and seeing how high a FSB you can go stably.

thanks for the replies

@zap, yes i am running memory 1:1
i think i must be running into the limit of the cpu, if heidifirst is right...no matter, will likely be upgrading to a q6600 when i start video editing...or might just hold off until nehalem gets more mainstream

I'd be very careful over FSB 333 to keep your PWM and northbridge chip / heatsink temperatures in check.
The cooling and PWM power systems on this board aren't quite as powerful as some of the higher end OC boards,
obviously, and I'd think they'd start to get warm at lower clock rates / power consumptions than other
enthusiast type P35 boards would.

With proper cooling (fans and possibly better TIM / heatsinks), though, I'd certainly think you might be able to
get into 400-450 territory as long as the power consumption of the CPU is within reasonable limits.
