Is it possible to put an AMD K-6 Chip in my Socket 7 with an Intel chipset?

If not, what is the fastest Pentium ever created? Will it run on the chipset?

I believe the fastest S7 Pentium was the 233MMX...though I seem to recall a 266, but they may have been for laptops.

What chipset do you have? You should be able to run a K6-2 (I assume you mean the "2") on your S7 board provided you have the proper Intel chipset & provided you board supports the proper voltage setting. Earlier chipsets (i.e. 430FX) were single voltage & won't support dual voltage/MMX CPUs...they normally only clock up to 200mhz. The later chipsets (430HX, VX, or TX) support dual voltage/MMX & will generally clock up to 400mhz with a K6-2...some even higher. That's because the K6-2 interprets the 2.5x multiplier setting as 6.0x. All these chipsets support the 66mhz FSB...though some motherboard manufacturers boosted the available FSB settings to 75 & 83mhz...even though these speeds weren't "officially supported".

One of the probs with these chipsets, with the exception of the 430HX, is that they only cache 64mb of memory. Therefore if you install over that amount, you'll actually slow your system because of the way the memory is accessed. The 430HX caches up to 512mb of RAM & was considered the chipset to have during it's heyday. The FX was known as the Triton, the HX was the Triton 2, & the VX was the Triton 3.

I am having trouble finding the appropriate numbers on the chipsets. I have two chips that say Intel PCIset. There are number long 8 digit numbers, no 400s, but they do indeed end in VX...?

There are two coltage settings, one is like 3.3 which it is on now, and the other is like 3.5. And there are 4 multiplyers.

If I can in fact but a K6-2 chip on the S7, is 400mhz the max, or can the 533 K6-2 also function?

As for RAM, I am not sure what you mean, I have 64 in there right now, and they are 32MB modules. I once tested a 64MB module, and it didn't register, might be max, but it could have been PC100/133, not sure, it was a while ago.

Thanks!

The 3 numbers before the VX are what you should look for. Your chipset should have a number like SB82437VX...but the important thing is the VX.

Do you know the make/model of your motherboard & do you have a user's manual? If not, the model may be printed somewhere on the board. Once you know what you have, you can do a search online for the manual. That will have all the various jumper settings listed plus a description of BIOS settings.

I doubt that your board will recognize any SDRAM memory modules over 32mb...it may not recognize 128mb modules at all, or they may only be recognized as 32mb. Also, if your voltage settings are 3.3 & 3.5, you can't run a K6-2 or even a Pentium MMX...but I suspect you're looking at I/O voltage, not CPU voltage. Most Intel MMX CPUs run at 2.8v, while AMD K6-2's run at 2.2v. You really have to ID your board so that you can find out what it supports. If you remove the CPU, there may be some info printed on the board within the socket that will help you know what CPUs are supported. Sometimes this info is printed next to the socket...sometimes not at all. Look for P54C, P55C or both. P54C means single voltage, non-MMX CPUs, P55C means dual voltage, MMX CPUs.

I think that for know, you should concentrate on finding out exactly what board you have. Once you do that, you'll have a better idea of what you can do with it. Post what you find & I'll be happy to help you out...

It's a 438VX. There is a 166mhz MMX Pentium in there. And I checked the voltage settings again. It says "CPU Voltage Settings" 3.38V, and 3.58V.

Are you sure you have an MMX CPU? The Pentium Classics (non-MMX) CPUs ran on single voltage..that is, the CPU voltage (internal voltage) & the I/O voltage (external voltage) were the same...usually 3.3 or 3.5 volts. I believe the recommended voltage setting was between 3.1 & 3.6v.

MMX CPUs run on dual voltage...CPU voltage of 2.8 & I/O voltage of 3.3.

If you indeed have an MMX CPU running on a single voltage board, you are very lucky that it didn't burn out, for it was not designed to run as such.

The visual difference between the MMX & non-MMX CPU is obvious. The non-MMX is a flat brown ceramic chip...while the MMX is black with a raised "core" w/MMX printed on it. The non-MMX should have the speed printed on the top, & the MMX will have the speed printed on the underside...it's the last 3 digits of the number...either 166, 200 or 233.

It's an HP Pavilion. The jumpers may be user simplified, but the chip is descrived looks like identical to the non-MMX, I know cuz I have a 133mhz sitting around. The core is not razed but it cleary says Pentium with MMX technology labeled right on top of the flat b---tard. I have looked beyond the case sticker if that's what you want.

There are only two sets of jumpers as I recall. One for multiplyers, and one for voltage, I can do a double check right now.

Thanks

Aha! Way on the other end of the mobo I found a set of jumpers for P55C! The settings are roughly from memory, 2.54V, and 2.84V. It's appears to be dual voltage, but the CPU and I guess I/O (Not familiar with that term) are the opposite voltages of what you proposed, are we still good though?

And indeed, a last check, I don't know why i didn't check before. I took teh CPU out, and the bottom reads, 2.8 Operating Voltage. The people printing the labels on the Mobo PCB are either morons, or I don't know what I am talking about.

I mean it says "CPU VOLTAGE" 3.5V, or 3.8V. I dunno. I guess it is wrong.

Well, just because I've never seen a flat MMX chip doesn't mean that they don't exist...LOL! I just dug up a couple of my old MMX CPUs to have a look. They are indeed black, with a raised metallic core saying "intel pentium w/ MMX tech" on it. On the underside, it says the same thing & printed directly under that is a 10-digit number. The last 3 digits are the processor speed...the particular one I have is a 200. Beneath that is another number along with the CPU voltage...MMX chips run at 2.8 volts.

What you (we) have to do is find out what motherboard you have...then we can get the manual & find out exactly what jumpers settings are available to you. You're gonna have to scour the board for a model number. Any info on the HP model number may be of help too. But you have to look over the board for it's model number as well. You might also be able to ID it from the BIOS string that pops up along the bottom of the screen when you bootup. Just hit the Pause/Break key during bootup to stop the process...then you can write the number down & enter it into a search.

Let me know how you make out...

Well for preliminary checks on the board model, I recall it being a P600, or P6000. The model of the Pavilion is 3100. The instructions for setting the jumpers is printed on the board. There are little table diagrams which show which jumpers to be set for the according voltage. I just don't know which voltages to use with a K6-2.

I want the 533mhz k62, but 400 i think you said is fine.

Anyway, I look the board over again, just wanted to give you what I knew right now.

Thanks again,

OK...take a look at this & tell me if it's what you have:

http://www.hp.com/cgi-bin/cposupport/get_doc.pl?SNI=pv3100&LC=personal_computing&Tfile=bph03721#P4_388

That's the one!

cept i just noticed, that there are two voltages on my board for p55c. 2.5 and 2.8 something.

small thing also...the order of floppy and ide connectors is backwards...either way thats all that seems different. but definately a pavilion 3100. and my board does say p2000, not p6000 as mentioned earlier.

OK...finally...lol! Are there any other P55C voltage settings? I just checked a K6-2/350 that I have & it runs at 2.2v core/3.3v I/O. So if you can get that P55C setting down to 2.2v, you're OK...but the best you're gonna get is 400mhz. That would be with your Host Clock set at 66mhz & your speed multiplier at x 2.0. Remember, the K6-2 will recognize the x 2 multiplier as x 6.0, so 66mhz x 6.0 = 396mhz (aka 400mhz). If you have a 533 already, you can use it, but it will only run at 400mhz.

If you can't get the voltage down that low, the best you're gonna get is 233mhz with a Pentium 233MMX CPU. The MMX CPUs recognize the x 1.5 multiplier as x 3.5, so 66mhz x 3.5 = 231mhz (aka 233mhz). You might be able to overclock your 166 to 200 by changing your multiplier to x 3.0...you might even get it to run a 233 if you're daring. Make sure you have a heatsink w/fan if you attempt to overclock. I've run several 166s at 233 without any problems...but I know nothing of this flat chip that you have...lol!

All other settings should be set at "default" from what I can tell. I think that's really all there is to it.

man, thats a bummer, i am not seeing anything lower than 2.54V... and i dont have enough multiplyers to overclock a 233, to like 300.

uhm, i dunno. i have a sentimental attachment to my 166 (being my first computer, lol) but i mean ebay sells 233 pentiums for like 5 dollars. jees, thats just too bad, i really wanted to make that thing pumped up enough to run a game of quake 3 on lowest settings (was gonna by like a pci video card), i just dont think a 233 will cut it! :(

any other suggstions before i consider buying a 233?

i just found this on amd.com

http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/21850.pdf

it shows voltage diagrams in the section "electrical data".

it took me about 2 minutes to load on cable...but when it did, it shows something like a maxium of 2.3v, and 2.5v cpu, and 3.6v i/o. the are typical and minmum settins too, that match what you said. I don't know what there are two maximums in the table...if u can check it'd be cool...

Well, you can try overclocking your 166 & see what happens. Other than that, look on Ebay for a 233 like you said. Unless you wanna shop for a better motherboard w/ CPU & memory...but I'm not sure what will fit in your case.

Anyhow, here's what I found doing a quick search for Quake 3 hardware requirements:

"For what it's worth, id claims the minimum hardware is a Pentium 233 with an 8MB graphics card, or either a Pentium II 266 or AMD K6-2 350 with a 4MB graphics card. That's probably pushing it a bit, with that kind of system power, don't expect to be playing much at anything put the lowest resolutions."

I believe the required memory is 64mb but it wasn't stated at this site...

u posted after me, look above your post just incase you dont know why the posts number is higer, i did say something :)

also after you read it, i can do a print screen image if need be. not sure where to post that, but u know.

thanks
