Jordan / Turbo PLL.. some explanation?

[sysfailur]

Well a few questions...

- What exactly do they do?
- How do they work?
- What boards do they work on?
- Where can you aquire them?

I'm thinking if it's possible to get one for my Asus NF2. That would be very nice... I have no clue if it's doable though. That's why I'm making this thread! :P

A regualr PLL converts the crytal's clock (4.77khz usuall) to whatever freq is requested by different MB components i.e. 133mhz to the northbridge, 8?mhz to smBus, crap like that

- How do they work?
exapmle. The stock PLL may only have settings for up to 200 MHZ FSB, and a 1/6 divider. A turbo Pll can get around this by manually sending a higher clock to the FSB/Northbridge. It can also be used to lock the PCI/AGP by sending a constant 33/66mhz to them instead of relying off a divider of the FSB.

- What boards do they work on?
ANY

- Where can you aquire them?
I dont know of any for sale. AFAIK you have to make them. I dont know all about it. Google, but take a tranlator cuz most of the tutorials are in japanese

its a differnt board
but you should be able to figure out how to make a turbo pll with this

Thanks for the info. Still confused, but thanks! Anyone else have some info?

btw if anyone can find the jordan pll or others in europe/us please tell me and I will buy lots of them.

wow , but max fsb is still limited by the chipset right? 200fsb on the sis 735 sounds nice...what do you think kt333 kt400 or nf2 can go to if you use a turbo pll? 250? or even higher? very nice collection of links!

Well I doubt 250, unless you could get ram that'd do that. And even then, it'd be tricky.

pc-3500? and corsair xms runs 220 with tight settings, i bet itll do 250 with still good settings!

I read in some review that nF2 can support up to 333mhz fsb Of course the one that we mean. now ur max is limited to 211 but the chipset can go to 333 or somewhere in the 300's its crazy fast and ready for the future or crazy guys like us who think we are one step ahead. If u can manipulate the fsb outside the bios u will get more than u can ask for or handle with todays hardware.

the new bios allows the a7n8x to hit 250.

i was looking to do a turbo PLL project a few months ago but i could not find any information on turbo PLL's for newer motherboard

i think turbo PLL's are a thing of the past:(

[Pegelius]

As long as motherboard has a PLL-chip, TurboPLL is possible to implement on the board. Newest mobos might require that the Turbo-module is also from newer mobo, but since it's only used for replacing 14.3 (REF), 24 (floppy etc.) and 48 (usb) frequencies, there shouldn't be problems with modules made of bit older motherboards PLL's.

On the other hand, i've heard that nForce2 uses internal PLL, so it makes things harder. On nForce2, there are enough FSB's allready, maybe not for diehard liquid nirtogen oc'ers, but for daily use anyways.

I've had TurboPLL on thee mobos now: K7S5A ,MSI 745 Ultra and now on MSI 486 mobo :) (it does ~70 fsb, if cpu can take it :) ).

Hallo Pegelius, good to see you here! I remember all the posts about your excellent O/C of the K7S5A at OCW, and that link makes me want to take my old K7S5A out and "revisit" it. Welcome! :D
