Difference between VIA chipset for AMD and Intel.. and some question on BP6

[Swakoo]

Whats the diff between Apollo Pro 133/133A and KT133/KT133a?

Also.. I am looking to start playing with dual mobo, and for starters thought I might get a 2nd hand BP6. But I am rather discourage by its lack of upgradability, though even it is only for starters.. (aiming to go dual power when AMD come up with their solution for the market, so meanwhile...)

I am from Singapore, and have problem locating the board at a proper price and a CPU to go with it as I only got one piece of 300a...

or should I get a slot1 instead? even if it means more $ just for starting sake?

 

[Swakoo]

anyone...?

If you do get a used BP6, make sure it's not one of the plentiful defective boards. The good ones are quite excellent. For info, refer to BP6 forum at http://www.bp6.com/Forum/

How do I tell if it is defective? is there a series of them that are so?

Have 2 offer.. one is refurbished by abit, the other is just a used board + 2 C333.. so guess its kinda proven

The Via Apollo Pro 133A supports AGP4X,the Apollo Pro133 does not,both are for Intel proccessors,the KT133A supports the new 266FSB(it can still run at 200FSB as well) speed so you can run the FSB at 133mhz externally if you use PC133 ram,the KT133 is 200mhz FSB, that runs at 100mhz fsb externally,the KT boards are for SocketA AMD processors.

Oh and one more thing, VP6 and some others socket dual can't run PPGA celerons.. but is it true that the MSI 694 can? would it be a better option then?

 

[Swakoo]

For BX boards.. the newer ones.. at 133fsb, AGP runs at 1/2 and PCI at 1/3 right?
But for the BP6 is that the case?

Cos my AopenAX6BC is so.. or so I was told...

Mem: What you mean by "...133fsb externally"?

 

[Swakoo]

Adding on to my question on defective BP6s... is there a range which is defective...

Would like to know if the highpoint on it is buggy or something like that in any way>?

 

[Mem]

Athlon boards run 200mhz or 266mhz internally but externally half this speed which is 100mhz or 133mhz that`s why you use PC100 or PC133 ram.

I love my BP6. It runs great. It is missing in upgradability, unless you are handy with a soldering iron......

 

[Swakoo]

so does anyone know abut the agp/pci divider @ 133fsb? since my aopen one is so.. was thinking if the bp6 is so too...

is BX a good chip for SMP?

 

[BigLance]

BX is a good Chipset for SMP, it is also one of the best for Memory performace.

 

[nweaver]

I don't know about at 133, I don't run my cellys over 100. At 100 it is 1/3 and 2/3....What are you going to run @133 FSB on a BP6?

 

[Swakoo]

I know... just wanna know the divider for PCI and AGP at 133 FSB for BX

 

[Swakoo]

so the only diff for Pro 133/133a is the AGP 4x..

and the onlt diff for KT133/133a is the support for 133FSB (effectively 266)??

Yes. The A means very different things in the two cases.

The Intel 440BX chipset does not support a 1/2 agp divider. Period. If you run at 133Mhz FSB your AGP will be at 89Mhz (2/3s) you can't get around that with any BX based board. This may not be a problem though, many new GFX cards can handle 89Mhz AGP. If your current board has 1/2 AGP, then it's not BX.

The newer BX boards can support 1/4 PCI though, so at 133Mhz the PCI can be in spec at 33Mhz. But the AGP won't be.

Defective BP6 boards have a capacitor and voltage regulator that don't have the capacity to properly support vtt voltage (memory bus termination, as I understand it) under intense memory access. The threads on the BP6 forum discuss this at length. There is a simple test, using Adobe Photoshop, that can identify the bad boards, as well as visual inspection of the capacitors and voltage regulators on the board itself.

Oh... if so then how...?
