setting fsb 100 to 133

[lamer_gamer]

Here's my deal: I want to OC my duron 700 fsb from 100 to 133 to run my pc-133 sdram at 133. So, if I've understood other posts correctly, can I set the fsb to 133, set the ratio to 1/4 to keep the pci bus at 33mhz, and then lower the multiplier to run about the same clock speed? I have a cheap ass hsf, so I really don't want to up my cpu temp (it sits right around 52-53C idle and even after playing 3d games for an hour or two), but I don't know if this would cause an increase in cpu temp or not. Also, would I need to worry about the cpu core voltage?

Why not get a not so cheap ass hsf and run it 133 * 5.5 = 731.5MHz.
I'm no expert on temps/oc but your temperature seems a little high anyway.

I've kinda thought my temp was a bit on the high side myself. I've been considering a Volcano II. I've never needed to change a hsf on a processor before, is it hard? I've put hsf's on, and obviously the thermal paste has, well, the consistancy of a paste! But when it dries does the thermal paste have any bonding qualities, or is it simply a medium through which heat is transmitted to the hsf? I'm just kinda chicken $hit to mess with a machine that isn't giving me grief 😱

Duh! Most important thing; Do I have the numbers and concept of OC'ing correct?

Best thing to do is to replace that hsf.
Once you have a good operating temp. then you can mess around.
I would try stepping up the FSB. I don't know what the steps are on your mobo, but for example 100, 105, 112, 133 etc.
Try the next one up and make sure the multiplyer is keeping your CPU at or below 700. Also try to keep the PCI factor below 40. I'm told its not too stable above this number. If you can keep it at 33 then fine. Like I said before, I'm no expert, so double check everything with someone else.
Oh! and remember the AGP speed. Some cards might not like too much o/cing.

Might be an idea to list your specs.

what mobo do you have? Most KT133 mobos don't do 133FSB (cannot get over 112-115 or so).

Unless you have a KT133A or better, you are not going to get all the way.

I have an A7A 266. It has the ALi M1535D+ northbridge which supports both 100 & 133 fsb. As far as keeping the PCI bus at 33, it is set to that either through the bios or dipswitches, depending on which you like to use. In the bios it's set by fsb/ram/pci (i.e.: 100/100/33, 133/100/33, 133/133/33). In any event I'll be upgrading my cpu soon, so I'm probably not going to stress out on it too much. Might experiment a little though since, after all, this one only cost me $40, and I'm not going to be trying to run it over 731 (5.5 multiplier x 133).

so you should be fine!
