URGENT!! Will a socket 5 , 7 motherboard support a Pentium 133?

[KennyH]

Kind of confused here. I have a socket 7 Pentium 133 and I want to know if it will work in a board that was made for socket 5 and 7? The motherboard is an ASUS P/I-P55TP4(XE). Please help me out here guys and gals. Thanks.

yes a P133 should work on a Socket 5 mobo.. in fact if I remember correctly the Socket 5 mobos support all the Pentiums that aren't MMX..

 

[oldfart]

That mobo is a socket 7. It will support up to a 233 MMX. I have that mobo with a K6-3+ 450 on it. That mobo is a very nice unit. It was the original overclockers mobo and still has quite a following. HERE is a web page with a ton of info on that board.

Thanks old fart and soccerman for the link and info!

It'll work. I have the same MB.. and it'll work with any P54C CPUs. (5V I/O).. but it will not work with any MMX though because it can not supply the 3.3V I/O needed for the processor

Not even with a powerleap adapter?

MadRat: it's not worth it.. it's a FX board, has slower memory then all the new chipsets. might as well get a new MB if I want to run with newer processors.

oldfart: the page you linked is T2P4, not TP4XE. T2P4 uses HX chipset, and is much better then the FX chipset...

 

[MadRat]

Don't P54c's go up to P200 non-MMX?

You may look for a Cyrix mII-266 (200's jumper settings - 266mHz is its PR rating), if you want excellent office performance. Seems like the mII was still single voltage, too. Their FPU sucks, but so does every cpu at that speed. hehe

esung, what are u talking about? oldfart has that same motherboard running a K6-3+.. also, notice in the name of the mobo (ASUS P/I-P55TP4(XE)) that it has the word P55 in it?

Soccerman:
The Link oldfart point to is the ASUS P/I-P55T2P4, NOT P/I-P55TP4XE that bp6 is talking about. T2P4 is HX chipset, which can support P55C (MMX) cpus, but TP4XE is using FX chipset, and it can only support P54C CPUs

Asus name all the MB in that period of time(Pentium) P55xxxx or AP55xxxx, it didn't necessary means it takes P55 CPUs. check ASUS's P/I-P55TP4XE specs to see the official spec. I still own a T4PXE and a TP4N, so I know what I'm talking about.

Question:
What is the difference on ASUS P55TP4XE, P55TP4XEG and P55TP4XEU?

Answer:
They are all the same specifications, just only differ in on-board super I/O Chip manufacturer and Infrared function.
P55TP4XE: SMC 37C665IR; Super I/O Chip with Infrared function.
P55TP4XEG: SMC 37C665GT; Super I/O Chip without Infrared function.
P55TP4XEU: UMC UM8669F; Super I/O Chip with Infrared function.

So basically when they say Socket-5/7 then it means it can handle both I assume. If thats the case then can you tell if you have jumpers that run up to 3X? If thats the case then I think you can probably throw a K6-233 or mII-300 on there. I've seen people dump then for as low as $10 on the For Sale/Trade forum.

esung-

Wasn't the VX and TX chipsets the only Intel chipsets that supported MMX?

 

[bernse]

HX did too. I had one of those mobos for years and worked like a champ on my 200MMX. If memory serves, you needed higher than a Rev 3.0 board for it though. Actually, now that I think about it, I don't think the VX supported MMX though... can anyone remember or bother to lift a finger to look?

 

[esung]

FX is the only board that I know it didn't support P55C CPU(the voltage is different, FX only supports 5V), the early VX didn't, but later on most VX boards adds support for it.

VX chipset supports SDRAM, HX didn't, but HX is a much better design then VX. later on Intel came out the TX chipset and replace HX and VX all together..

most of the CPU that came out after MMX is on 3.3v, which can not be put into the P/I-P55TP4(XE(G/U)/(N)... except the RISE MP6s and some Centaur CPUs that was design to take 5V and 3.3V.

 

[MadRat]

I've used the mII's in Socket-5 boards, though, so that doesn't fit your scenario. The FX should support most of the 3v single-voltage cpu's. They didn't support the split voltage, true, because the split core ran at 2.5v if I remember correctly.

 

[oldfart]

There are also undocumented voltage settings. I have that board set @ 2.0 V to run the K6-3+ 450 CPU.

 

[MadRat]

So how'd it turn out?
