Which is better: 112 fsb x 9 or 133 fsb x 7.5 ? I'm confused...

New member here. Like this forum because you guys seem to know what's up and there's a good vibe.

I've unlocked my Duron 750 (AKCA-Z) on an Abit KT7a mobo, but don't know what settings will bring about the greatest performance boost. I've been reading a lot of articles/tips/reviews/posts from ALL over and am getting conflicting advice:

1) Set the FSB to 133 and the multiplier to 7.5. The extra bandwidth on the fsb lets you make full use of PC133 memory on a via kt133a board which supports true 133 fsb speeds. I've read that benchmarks show that a 133 fsb is the best way to go.

ON THE OTHER HAND

2) Set the FSB to 112 and multiplier to 9. This way pci runs at 37 and agp/ide runs at 75. Memory can be set at HClk+PCICLK which would equal 149 mhz. The thinking behind this oc setting is that more is gained here by the fact that everything is sped up, not just internal CPU speed.

So... I'd like to hear your thoughts and advice on the two different settings and what might work best for me.

Thank you for any help (or slaps upside the head).

Here's my rig:

Duron 750 (AKCA-Z)
Abit KT7a
256 Mushkin cas-2 PC133
Diamond Stealth III 32mb PCI video
Soundblaster Live Value
Supramax 56k internal PCI modem
Maxtor 60G 7200 ata/100
52x cd-rom
TEAC 4-4-6 USB cdrw

as the common rule, a higher FSB is = to higher visible performance gains.
however, if your overclock is successfull in both forms, why not just run a benchmark and see what YOU prefer?

personally, i'd go for the highest FSB... sometimes you can get a better O/C with the multiplier, so it really comes down to personal luck of the draw.
based on the ability of the other components tolerance to O/C'ing is where the FSB lies... i'd try this with as few cards installed as possible.
the multiplier is my resort after i can't get higher. because you may reach.. let's say.. 860 with FSB O/C but 933 utilizing the multiplier.

then, consider if the 860 actually "runs" better/faster than the 933 with some bench tests... i've heard strange things here LOL
i guess in gaming FPS is the important factor, thus FSB is the key..
whereas biz apps would probably benefit from higher clk multiplier.

hope it helps bro!

Yes a higher FSB is bett to a degree-as long as it is stable. Id fo for just FSB, not +clck because with your RAM and that board you can get alot higher than 133FSBfor sure, as long as ther is good cooling. try 7x145 or something like that, that is 1015 mhz-not bad for an 800

Hm. Remember that higher FSB is over specs. shorter the life of the cache will be!

P.S.
But at other points,I fully agree
