100 FSB or 133 FSB? 100 but higher speed

[Liquidsky]

I got two processors. They are both Durons. Now what would be better my 750@1000 (133mhz fsb) or my 900@1100 (100mhz)?? My mainboard's a MSI K7T Turbo. Can't make up my mind.

I would imagine that the 750@1000(133) would be a little faster than the 900@1100(100). That's because even though your cpu is running 10% slower, the rest of the system (ram, pci, agp...) are running 33% faster.

I'd suggest running Sandra and comparing the two results on all the tests. Then decide what is more important to you, the cpu only, or the whole syste.

If you run a lot of math intensive applications, then a faster cpu would be good, but if you wanna play games and such, I'd imagine you'd want an all around faster components.

I may be wrong here because things are so close between these two settings. Run Sandra and see.

I agree with the above. However, I would do some benchmarks, and compare the results. Let us know the answer, I am curious about this...

133mhz FSB would definatley be faster...because of the memory bandwidth. That is what gives the system more speed...I would DEFINATLEY choose the 133 FSB...

And why not OC the 750 a little more, to get it more close to the 900. A little push on the FSB and multi and you have it (if the CPU will go stable to that point tho !)

I'd lower the multiplier on your 900 and run it at 8.5x133 FSB (1133 MHz) if you can. Otherwise, run an 8 multiplier and up your FSB by 1 MHz increments as far as you can.... you should, at an 8 multiplier, be able to reach at least 8x138 FSB (1104 MHz). 5 extra MHz on the FSB is hardly anything. Just remember, you're not locked to either 100 or 133 on the FSB. You do have some choice.

Well see i would clock my duron 750 higher but right now i'm stuck at 966 (7X138) using a 1.85 vcore. I know that it works at a maximum of 1050 Mhz but I just can't get that 7.5 multiplier to work properly. whenever i use 7X133 my PC won't boot up. My K7T Turbo just beeps like hell. there's like totally something wrong. Got any ideas to fix this problem.

On the other hand my Duron 900 works fine at 1100Mhz but i can't lower the multiplier cause when do that and up the FSB my PC won't boot. It has something to do with the motherboards that aren't 100% jumperless. It uses the 900's 9X multiplier to boot up before it uses the one set in the bios. It was a totally a bad idea to think that MSI could make good boards.

What should I do. that's the question. can't make up my mind. if only i could get that 7.5x multiplier to work.

[deez]

can you run the 900 at 9x multiplier and 133FSB. I had my 900 at work running at 133FSB with retail HSF and .05 increase in vcore. mobo was epox 8kta3 and stepping was ANCA temps maxxed about 47C

using a non oc athlon now

If you can run at 1100 then I imagine you can run at 1200 with a little extra cooling
