I'm doing this for fun.
Does anyone know the correct jumper settings for this processor on the Amptron DX-9700 m919v3 motherboard?

Its an Intel Pentium Overdrive Processor model BOXPODP5V3 aka P24T and is rated at 83MHz. I've tried looking for the jumper settings form here http://motherboards.mbarron.net/index.html but they just don't list it in the jumper manual.

Here are the motherboard specs

If he was tweaking an i7 you wouldn't have said that. :rolleyes:

The thing is, I know him in rl and he doesn't tweak his i7, or c2d, just his pentium pro, pentium 3, pentium 4. Its amazing.
 
Shouldn't it be the same settings as either a 33DX or 66DX2? I thought these overdrives were intended as drop in replacements.

First of all I sold my Core i7 975 Extreme and the motherboard. Second my Core 2 Duo doesn't need overclocked everthing runs fine even GTA IV. I also can't say I'm satisfied with the temperature that both Cores are running at. However I will have to do something about the air flow in the front of the case, so I am switching from the Cooler Master 1100W UCP to the Silent Pro. I don't tweak my other computers either I'm just going to finish building them. So far its been fun watching the Amptron DX-9700 count 256MB of RAM which is as far as I've got for now. When I get the hard drive I will configure the SCSI hard drives and install the OS. The Intel PR440FX with Dual Pentium II Overdrive Processors needs alot more. I will install Windows Server 2003 on that then maybe Linux. Then I have A the Super Micro PIIIDR3 serverboard that will have Dual Pentium III 1.0 Ghz and 2GB of RAMBUS ECC at 3.2 GB/s. None of this is really that advanced compared to my Asus Z8PE-D12X server motherboard, but it all in good fun and gives me the chance to experiment with different types of SCSI interfaces.

No they are not which I learned the hard way when I almost fried the mosfet on the motherboard when I accidentally set them for P24D instead of the P24T which is what I need to know the jumpers setting for.
 
I can remember dreaming of something like that system... the possibilities of a computer that fast... hmmmmm :)
 
HOLY SHIT 83 MEGAHERTZ

overclock it to 84mhz, and it will be a great success..

LOL However, this is not possible. The mulitplier is 2.5 and the FSB choices are 25MHz, 33MHz, 40MHz, and 50MHz. This means that the only Speeds that are supported are 62.5Mhz @ 25Mhz, 82.5Mhz @ 33Mhz, 100Mhz @ 40MHz, and 125Mhz @ 50MHz.
 
I can see some jumper setting tables silkscreened on the board, as was typical back then. Do these not contain the settings you need?

No Sorry to disappoint you, but the only table on the motherboard only shows the jumper settings for the FSB.
 
Geez this makes me feel young. My first PC was later-gen K7. XD

This is not one my first computers. I bought the parts for this one ebay several years ago and this motherboard in like 2008. My first computer had a 286 processor that I got from an uncle in like 1996 and not long after that my Dad bought our family an IBM Aptiva with an AMD K6 233MHz processor. The first computer I built had a Pentium III slot 1 Coppermine 533MHz with an Iwill VD133 motherboard that sucked ass because it didn't support ACPI for Windows 2000/XP, so I built a computer with the 1GHz socket 370 Pentium III Copermine that I used in a slot to socket adapter for the Iwill motherboard with the Abit ST6-Raid till about 2005 when I scratched a trace on it and rendered it unrepairable. I attempted to purchase a gigabyte 8KNXP Ultra off ebay around that time and ended up with a dead motherboard. After I RMA it they sent an 8IPE1000-Pro G which I used until I got the Supermicro P4SCT+II to use the P4 3.06GHz. Now I am currently using a Moblile Pentium 4 3.46GHz because of the higher multiplier which I intend to use to overclock and L2 cache since it has 1MB instead of 512KB. During Christmas break from college in 2008 I ordered the parts for my current system which used the Asus P5E WS Professional and the E8600 Core 2 Duo Wolfsdale at 3.33Ghz

How much a board like this priced new back then? I had a chance to see old AT boards in person a few times. I could not believe how simple they were design and manufactured. They could almost run forever.
 
Fucken wow some of you are young fuckers....... I remember when that was hawt shit in its day.
 
Sorry to disappoint you but this does not show the jumper settings for the P24T.

Then it's most likely that all the information on the board was out and finalized long before there was a P24T, not to mention that this is also a PCchips group board. Not the most reputable company out there.


EDIT: Since the the chips you're wanting to use is supposed to be a drop-in replacement for a 486 DX, have you tried using those jumper settings rather than the P24D settings?

I had one of those and from what I can remember it smoked the early Pentiums that my friends had. :D
 
Is the P24T derived from the P5 or the P54C? The reason I ask is that if it is P5 derived, it likely has the FDIV bug. I remember that they were out at about the same time, but I never actually HAD a P24T of my own to know for sure.

I was an AMD guy at that point between the Intel 386 day and the Pentium MMX days.

I believe it was P54C. The P24T was released long after the FDIV embarassment.
 
Gawd.......I remember the day when I would've killed to get my hands on that

/up hill, barefoot, thru the snow
 
Otherwise, it is an upgrade processor designed for a drop in replacement for a DX2/66. Pin the board out for a DX2/66, and you should be good to go.

+1! :p I remember being SO jealous of my friend's bleeding edge 133mhz Pentium system. It was even in a tower case. Man, that little fucker's parents spent like $2000 on it.
 
I couldn't believe it the day my parents bought a Pentium 200 MMX. It blew my mind and everything it put into it. I wish I still had it.

Many people are suggesting that since this is intended as a drop in replacement, that you simply try dropping it in. Are you sure it won't work? It may be that this board revision does not support it. Why is there a Canadian flag on the motherboard?

My first actually owned by me PC was a P133 with 24MB of EDO RAM, Packard Bell. Boy that PC was a freaking awesome PC for it's time. Even had a blazing fast 33.3 kpbs modem.

Before that, I used my Commodore 64C PC for everything.

This board is based of the UMC chipset not PC Chips like the m915 I had before which had the jumper setting for the P24T but lacked one jumper to make the processor work and after many failed attempts I was unable to get the board to work with anything. This is also version 3 of this board and version 1 supports this processor, but none of the manual show the jumper settings for the P24T. The problem is that no one has the original manual for these boards which shows the correct jumper settings. All I can find are text decuments and websites, but not the original manual. This is not just a drop in replacement because as I mentioned I almost fried the mosfet by using the P24D settings and this includes the 486 settings because I thought the AMD 5x86 was a 486 when went to put it back in after attempting the Pentium aka P24T.

I'm saying the manufacturer of the board is PC Chips, or more properly Hsing tech. they used aliases such as Amptron to get around their shoddy reputation. I've run across several posts mention that the manual is only four pages long, and given the age of this board, and the reputation of the manuafacturer, it's believable

P24D is a later revision of the 486DX/2 What I'm saying is to use the setting for the plain old 486DX (aka P4). If you've done this already, and I'm misunderstanding you... I apologize. If that's the case, then it may just be a bad processor, or the board is simply incompatible, despite listing as so. Intel did change the specs for the 486 POD line after many board manufacturers had already produced boards in compliance with the originally publish requirments, which caused a lot of headaches when they finally did release the final product.

As for your mosfet's getting hot.. that's probably because the Pentium Overdrive consumes up to 15w where the 486DX/2-66 only used up to 6w . So you have have nearly 3 times the current going through cheap components. What do you have your voltage, FSB, and multiplier jompers set for? Should be 33MHz, 2x, and 5v.

Since we're all going down memory lane, I guess I'l jump in. My first computer was an IBM-PCjr my parents bought me for christmas in 1988. It had a an 8088 that blazed along at 4.77MHz, a whopping 256k of ram (128k internal, 128k sidecard), and an enormous 360k 5.25" floppy drive. Around 1994, The first computer I built was in 1995, it had an Am486 DX/2-80, 8MB RAM (8 30-pin SIMMS), a 1.2GB hard drive. I REALLY wanted a Pentium... but they were still too expensive.

I could be wrong, but aren't older systems horrible with power consumption, heat, and PSU efficiency? It wasn't really a priority back in the day so I don't have numbers. I can understand the desire to tinker, but you might be better off tinkering with something more modern and cheap.
