Intel 440LX vs VIA Apollo Pro

Postby appiah4 » 2017-11-10 @ 09:19

I'm considering building a Celeron Socket 370 system, and I have two boards I can use for this. One is a 440LX (ZIDA Tomato LX98-CT) and the other is a Via Apollo Pro (ASKA SST-5830). There are many comparisons of the 440BX vs Apollo Pro 133, but I can't find much comparing the LX vs Pro. Is either of these chipsets better than the other by a good margin?

Tomato board. The horror.

LX is a very good and stable chipset limited by a slow 66Mhz FSB.

Apollo has support for 133FSB and some other nice stuff, but from what Ive read there are issues with the AGP bus in certain motherboards.

Only Apollo Pro 133A has official support for 133MHz FSB. Apollo Pro only supports 100MHz, but still beats LX's 66MHz.

The Apollo pro supports faster CPUs, so if you're going for performance it's the obvious choice. Zida 440LX/440BX boards are a bit of a mess, I'd stay away from those.

Nope. All Apollo Pro 133 chipsets have 133MHz FSB support. OP's board is a regular VT82C691, so it's the non-133 version. The regular Apollo pro 133 is VT82C693A, and the 133A version is VT82C694X - the difference between the two is AGP 4X support, witch the 133A has and the 133 non A does not. The 133A also supports up to 2GB of ram as opposed to 1.5GB for the non-A version. The VT82C694T has official tualatin support (Pro 133T).

There are Apollo PRO VT82C691 boards that can handle FSB 133, and have options in BIOS for it - including a divider to run PCI at 33MHz and AGP at 66MHz.

You are mixing up VIA chipsets. its the Socket A KT133 that only supports 100Mhz FSB with the KT133A being required for 133Mhz FSB.

some KT133 non-a boards like low end stuff made by Acorp and Jetway do "support" FSB133 via BIOS update. It also has a FSB 133 jumper on the motherboard. With the bios update, the board supports all FSB 133 (266) cpus - w/o it, it refuses to post @ 133MHz fsb with anything other then a Duron CPU (overclocked of course).

Considering the KT133 is officially only specified for 100Mhz FSB, any 133Mhz "support" is overclocking the chipset. In my experience Kt133 stability gets REALLY iffy once you go past 115Mhz, if it even gets that high. But when has questionable stability and compatibility ever stopped any budget board maker?

Precisely :) I do have a KT133 acorp board witch can do 133MHz right. You jumper it for 133 (it has a JP19 - open = 100MHz closed = 133MHz), and it will post at 133MHz with PCI Clock = 1:1/4 and AGP clock = 1:1/2 witch I find a bit wierd for something designed with 100MHz fsb in mind. The earliest KT133 board I have has jumpers for AGP and PCI clocks like a super socket 7 board. Weird.

It's a shame on me... I had owned a pro133 board around year 2000.

That's a long time ago. I forgot most of this stuff myself - thank good for datasheets.

Well, this discussion appears to have veered into mostly Apollo Pro 133, but I believe the board I have does not have a Pro 133, just a regular CT82C691Apollo Pro?
