I am a PC repair tech and I have this customer of mine who has an older board with an Intel 200Mhz (not sure if its the MMX version or not but could almost swear it is), with 32MB of EDO 72-pin SIMMs, in an older mobo. He wants to upgrade to Windows XP, so I went inside the PC to get the specs on the board and see if it will take a faster CPU. Well I couldnt find a model number, all I found was this this series of numbers which I think has something to do with the chipset: PIIX4 82371AB, anyways, I looked at his bus frequency and it goes upto 83Mhz, and his multiplier goes upto 5.5, so I assumed from that without looking at the specs of the board (because I cant find them if I dont know what it is) that it will take a 450Mhz CPU (83 x 5.5 = 456.5), I also looked at the voltage and it takes all the common socket 7 voltages 2.2/2.3/2.8/2.9/ect..., and since AMDs chips are 2.2 volts I am was assuming this board will take an AMD K62-450MHz CPU, right? I did look some of them up but could only find 100Mhz bus, does this matter? Will this CPU run fine @ 83Mhz? Also, he needs to upgrade his RAM obviously, his board does take DIMMs, im guessing PC66 DIMMs, but how do I know what the max it will take is? I was thinking of purchasing 2 sticks of 64MB to give him a total of 128MB, which sould be plenty for WinXP.
Your a PC repair tech? holly crap, I'd never trust you under the hood of my pc.
Anyways your gona need pc100 memory if your fsb is going to be higher than 66mhz. Yup that cpu will work with that mobo but amd k6-2 are not all 2.2V.
As far as your memory i dont now how much it can take because PIIX4 82371AB is not your chipset. To determan your chipset bownload a freeware program like WCPUID.

I agree with Derk...I wouldn't want you working on my machine...LOL!
First of all, you have to find out what chipset you have. Many older socket 7 chipsets would only cache 64mb of RAM. If you install more than that, you'll slow your performance...but being a PC tech, I'm sure you know that.
Also, many boards, even though they have the 83mhz FSB option, will not run at 83mhz...that's because the PCI bus runs at 1/2 FSB speed. 41.5mhz is just too high for the majority of PCI cards. It will work though, if there's a setting to clock the PCI to 33mhz, regardless of the FSB setting. 75mhz FSB would probably be the better choice...EDO SIMMs will run at 75mhz without a prob & if you set your multiplier to 2.0, the K6-2 will recognize it as 6.0...so you'll be running at 450mhz (6 x 75). Most PCI cards will run at 37.5mhz without a prob.
The only other issue is voltage. Some K6-2's are 2.2v...others are 2.4v. If your board supports the proper voltage, the K6-2 should work, provided you clock it correctly.
One other option would be 66mhz FSB. Set the multiplier to 2.0, & you'll be running at 400mhz (6 x 66) & your EDO RAM will be running at it's designed speed...& so will your PCI cards.

Well excuse me, im not familiar with all the older generic boards & their chipsets. I saw the PIIX4 and assumed it was the model and thought I could go from there, but couldnt find anything but a datasheet from Intel for manufacturers telling them what bugs are in whatever it is. And as for the voltage comment, I did NOT say ALL AMDs run at 2.2, only that I know AMDs run at 2.2 volts, meaning I know that there are chips out there that will run at 2.2. And since Intel's socket 7s only go upto 200Mhz, and Cyrix chips suck, that AMD is the only alternative. I did not know about the socket 7 boards not being able cache the RAM
above 64MB though, never heard that before. Thanks for repling, thought the answers didnt have to include the fact you think im ignorant. And may I ask exactly, what makes me such a bad tech?

Perhaps the fact that your an idiot? i'm sorry...but most technicians are supposed to be dealing with older machines...whilst newer machines may come your way, older machines are still more common place then you think..and don't question me till you've writtin 15 exams...2 to become a repair tech, the rest on system administration...i agree with the other guys though...i would never bring my PC to you...and FYI, all mobo's have an identifier on them..ALL of them, its a requirment...so you ain't lookin hard enough buddy..

So, lemme get this right. Just because I was unsure if a 100Mhz bus CPU would work stably in a 83Mhz board, im an idiot? That just makes no sense. Like none of you never need a little help once and a while, I though this board was for just that, because we all need some kind of help once and a while! But now I realize that its not for that, its to show others how smart you are and make fun of people who ask a simple question. If I'm all that dumb exam guy, send me an exam! Test me! Post a few questions! I assure you I an not dumb! And I am fully capable of the job that I do! I was simply unsure of something, I would rather post and take crude uncalled for comments all because of doubt than to pay for the parts and have them not work correctly and have to pay a restocking fee!

Oh as for the identifier, im sure it does have one, the problem is that I though it was the PIIX4 82371AB, then when I couldnt find a mobo with that model, I figured maybe it has to with the chipset (didnt say it was simply said it has something to do with, which it does, still dunoo what but it does). I couldnt find any other identifier and was not going to pull the whole board out when I thought I found the model number.
0
Also, the fact the guy is 40miles away, otherwise I would just go back and see if I could find another number on the board. And thats another thing, if Im such an idiot, why do people from all around my area upto an hour away from my city (which isnt big nor small many other techs in my area) call ME to come fix their PCs???? Most of the time its to fix some other morons messup!

The old Intel socket 7 chipsets (430FX, 430TX, 430VX) only cached 64mb of memory. The 430HX cached 64mb as well, but if a specific Tag RAM is installed on the board, it will cache 512mb. Go to the following site & scroll down to the chipset/cache table & you can check it out for yourself:
http://www.makeitsimple.com/articles/ramguide/ramguidep6.htm
I was just informing you that there are both 2.2v & 2.4v versions of the K6-2...there are also mobile CPUs that run at 2.0v. I'm running a 2.0v K6-2/475 mobile CPU on my backup machine.
As for your question about being a bad tech...Tyson kinda answered that in his reply. I would think as a tech, you'd be familiar ALL kinds of different mobos, chipsets, CPUs, etc...including 486s & socket 7 equipment...not just Athlons & Pentium 2, 3, 4. A lot of people are still getting by with their socket 7 systems & I would think that you'd have seen your fair share of them.

I have seen a fair share of them. I was simply unsure if a 100Mhz CPU would work in a an older board that doesnt have a setting for 100Mhz, why cant you people understand that simple concept???? And just because I was unsure dosnt make me an idiot! And thats my point! I thought the CPU would work and was about 95% sure, but was that worth spending my own money and my customer's money on a guess??? I just wanted to see what you all thought and hoped someone would help with backup my decision! I can understand if I came here asking how to install Windows or something simple and stated I was a tech, then yea im in some trouble, that would make me a idiot! But I still fail to see how my question makes me an idiot. I never was good in school, I even dropped out, but dammit all I have is computers and with out that im nothing! And when someone insults that I get a little pissed off, im sorry if I took it the wrong way, maybe you were joking, but I took it personally!

Ha finally found something on it! Here is a link to what the PIIX4 is/does exactly, the guy is taking about it for a Linux system but you get the idea: http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/busses/i2c-piix4, that was really bothering me that I didnt know WTF it was...

By announcing yourself as a PC tech & then asking a question that a PC tech should know, you set yourself up for abuse. Had you left that little bit of info out of you original question, you probably wouldn't have gotten the responses that you got.
I think this PIIX4 82371AB chipset that you're speaking of is the southbridge chipset...normally boards are referred to by the northbridge chipset. At the risk of pissing you off again, a PC tech should know that there are usually 2 chipsets (north & south) & know which is which...this is common with almost all boards, not just the old Intel socket 7. If you can take another look, find the other chipset that ends in something like 437TX, 438FX, 439VX, etc...that is the one you need to know. The 430 number will vary, but it's usually 437, 438, or 439. Actually, all you really need to know is the last 2 leters (i.e. TX, VX, HX, FX, etc).
If you still don't know the model number of the board, try going to motherboards.org & using their motherboard ID tool.
Here's some more info on chipsets:

Intel makes a 300mhz pentium mmx
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL34N&ProcFam=51&PkgType=ALL&SysBusSpd=5098&CorSpd=5023Mr.pc tech fool, You said they only made a 266MMX
0
Derk -
I gotta admit that I didn't know about that one myself. I knew there was a mobile 266MMX socket 7 CPU, but didn't know about the 300. When it comes to socket 7 Intel desktop CPUs though, I believe the Pentium 233MMX is as high as it gets.
0
No, Mr. Dick, uh hum, excuse me Derk, what I said was that Intel's socket 7 CPUs only go upto 266Mhz MMX, look at the page you sent, this is a mobile processor, I have this CPU in my Toshiba Satellite 2535CDS, its not a socket 7 processor, in fact its built onto the board and cannot be removed.

Mr. dumb tech dud the only P266MMX is mobile.
http://processorfinder.intel.com/scripts/list.asp?ProcFam=51&CorSpd=5020&SysBusSpd=5098&PkgType=ALL

Yes, the 266Mhz is mobile CPU, but as I said the 266Mhz MMX is the LAST SOCKET 7 processor. The 300Mhz MMX you were reffering too IS NOT A SOCKET 7 PROCESSOR! So get the facts straight before you call someone dumb...

Well, hey, you started the name calling when you called me a "Mr.pc tech fool". And I'm not yelling cuz you called me dumb, I'm yelling cuz you can't read correctly, yet you try to call me dumb. Anyway, I'm through with this post, I already ordered a CPU and RAM, if it works it works, if not I'll upgrade the board for free, I have a few laying around that will work. Anyway, It was nice arguing with you Derk, thanks for the tips Jam, and Tyson, well what can I say? Except that its shame I didn't get to prove how competent I am with one of your exams...
