2100+ Aiuhb 0301 overlocking: FSB or Multiplier

[mattford11]

i havent had mucch luck with my palomino 1700+, ive been able to get it stable @2000+ but this new tbred is a whole different story.

i am goin to pop this chip in and what should i do... Fsb x 11 or 133 X X(Multipiler) or combination.

Im runnin KT400 chipset gigabyte mobo
512 DDR 333 (mushkin)
and a Zalman NPS6000CU - Noiseless Socket A/462 CPU Cooler (pure Copper)


Thanks for the advice on what to use or what u guys have had the best luck with as far as fsb/multiplier Combos!

Try to figure how far your cpu will do FSB wise by doing something like 12.5/13 x (X of MHZ). If it can hit like 2600/2700XP speeds, then back down on the multiplyer to 9-10 and work your FSB MHZ up to 200MHZ. THats if you have good ram that will handle 200mhz .

i was thinking that it should go 155 x 13 or 160 x 13 easy right since i got that mushkin
i was hoping to hit that 2.13 (2600+) which would be like 164 x 13 that would be awesome

more replys welcome!

update: i think that my ga-7vaxp mobo only hits 12.5 multiplier max!



time to rework the numbers..lol

I think (and I could be mistaken) that you'll want to end up with the highest FSB possible even if it means losing a couple of mhz from the benchmark along the way. I haven't done this in practice yet (I will be starting next weekend) but I assume that you'll want a higher fsb simply because it will give your system more bandwidth to work with which is a more powerful thing that a few mhz.

bump!

Your 5/1 divider kicks in at 166MHz fsb, so start there with the default multiplier (13). It should do it at stock voltage. If not, either lower the multi, or raise the voltage.
Your mb will offer multipliers based on the cpu you put in there, so you'll have the default 13.
I'm sure you'll be able to hit 166MHz fsb. After that if you want more, just watch the pci frequency. Try to keep it 40MHz or less. At 200MHz fsb you should have a 6/1 divider kicking in. Who knows if your memory can handle it?
You may or may not end up needing to hang a quiet fan in front of that Zalman.

Well.. i seem to have hit a wall @ 13 x 150

system wont even post above that...

im kinda concerned that the memory shows 366.7 mhz in CPU-Z, i thought that should stay @ 333mhz....

any suggestions welcome, thanks

Try to jump from 150mhz FSB to 166mhz FSB. That'll hit your 1/5 PCI divider, and your PCI/AGP slots won't be out of sync.

If needed, raise the voltage.

I'd say, the Maximum "safe" vCore for tbred-b's are about 1.8v. I would hesitate to go any higher. For memory, 2.8v is pretty high, but quality memory should be able to take it.

Goodluck, let us know on your results.

Sounds like your pci is going to high. Can you see what the pci is running at when you are in bios? Usually it will be listed as part of the fsb setting, like "133/33," or "145/38." Also, your memory is not running in sync with your fsb. Running it in sync will give you better performance. It says your memory is at 366MHz because it runs higher as you raise your fsb, and you set it at 166MHz.
I would set the memory in sync, and put the fsb at 166, thereby running your pci at 33MHz, which is what it likes. I bet it will work with the default multiplier. You may need a little more voltage.
