overclocking 1.6a on bd7

I have an Abit bd7-raid with a p4 1.6a, 2 sticks of kingston ddr 333
I am stuck at the fsb of 140 it wont load windows anything higher than that
the ram is at 1:1, i am using 1.6v vcore. Why cant it go higher?
I have seen many 1.6a s go higher than that What is wrong with it. what is the bottleneck

This is my friends comp and he asked me to overclock it for him and I thought it could definately go higher than that
but mebbe im wrong
 
memory limiting you? what fsb:mem ratio are you using?

chip limiting you? have you oc'ed it before?

mobo limiting you? (most likely) different bios?

🙂
 
the mem ratio is 1:1
i doubt the cpu is the limitation.
I just updated the bios to the newest one the origonal could do same thing
i doubt its mobo as ive seen people get 192 fsb with that mobo and a 1.8c1 chip
also it has a swiftech mcx-???? heatsind and fan for p4 478

 
my first thought was that it was the ram. Couse if i go above 140fsb it has windows file corruption errors, which are most commonly caused by ram. But that ram is already above the motherboard specifications. it uses 200/266 im using 333 which is supported by the newer bios but is run as 266 or somethin like that so as i see it the ram shouldnt be limiting it but thats the only thing that looks like it might be
 
Try pulling one of your sticks. I doubt it's the cpu also. Try upping the v-core also. What memory timings are you running? 🙂
 
The agp/pci is locked??? Cause HDD errors due to too highof a pci speed can also cause this...
 
Like Duvie said:

go for 33MHz PCI and 66MHz AGP.

Anyway, I've a 1.6A at 133MHz, it worked fine up to around 150MHz, only problem was I couldn't set up AGP/PCI timings to my liking. So I stuck at 133 because I use onboard sound, USB and so on. My main issue is stability...
 
the agp/pci bus is locked. i have tried up to 1.7 vcore without any changes in results, I will try pulling one stick of ram the next time i am there
