Specs: Windows XP, Intel P4 1.9
good evening. here's the thing people. I got my very first help here on an older machine, older than the old ones i usually work on lol :)

recapping : it's a p5mvp3 mobo, with a lucky tech bios chip. i had made this pc (using a amd k6-2 350AFR about a month and some ago) for the coolest little 7yr old boy on my block. he's always looking out for my 5 yr old and .. he's just the kind of kid that people like.

his dad called me today all happy, telling me he has a much faster cpu and that he'd want me to do the swap. i agreed, and i've been messing with this thing for three hours. it's a AMD K6-2+/500 ACZ, and i thought i'd just pop it in instead of the old one and i'd be done. not the case.

-boots fine, but shows me the craziest values on post, for the mhz. anywhere from 40mhz to 60mhz :)) what the hell ? am i missing the best multiplier/fsb setting? i've raised the voltage to 2.2, afraid to go any higher just yet, and don't see a reason to. these run on 2V. is this a bios issue ?

this is from the manual : "Specification
 VIA Apllo VP3/MVP3 dual Design AGP/PCIset chipset
 Intel Pentium Processor , Pentium Processor with MMX
technology , AMD K5/K6 , Cyrix 6x86L/6x86MX & idt C6
operating at 120~500MHZ with 321 ZIF socket 7 provides
scalability to accept faster Processors in the future .
"

help, i'm attaching the manual again :)

I always say it's best to doublecheck.

A K6-2+/500 should run at a default 100Mhz x 5.0 multiplier.

Some motherboards required bios updates to run this chip.

Another way out might be to try the 350 @ 100x4.5 or 100x5.0.

If you've got the jumpers set right then it's probably the bios, as already mentioned, or the cpu is bad. I found a bios file here:

http://members.driverguide.com/driv...

It may be older, newer or the same as you've already got. You'd need to get an Award flasher to install it. Unless you're familiar with bios flashing it may be best to just use the 350 mhz, as flashes often go wrong.

In the scheme of things you probably are not going to notice much difference even if you could get it working.

As I recall the voltages required are different. Some chips even had dual voltages. The motherboard has to support those features. All the settings were done with jumpers too. Setting the voltage wrong can result in instantly frying the chip.

Just above this response is a box with links to Related Posts. You probably could get more info by following those links.

"it's a p5mvp3 mobo, with a lucky tech bios chip"

No, it's a LuckyTech P5MVP3 with an AWARD BIOS.

http://www.elhvb.com/mboards/luckyt...

As you said, the K6-2+/500 ACZ runs at 2.0v. Notice the "+" in the model number? That means it's a laptop CPU. There is absolutely no need to overvolt it. If you still have it at 2.2v, set it back to 2.0v.

http://cpu-museum.de/?m=AMD&f=K6-2

"i'm attaching the manual again"

You can't attach files to posts. If you want us to look at something in the manual, post the link to the download page.

Make sure you properly configure the jumpers. Obviously you should have 5 x 100MHz @ 2.0v. And make sure to lock the AGP at 66MHz.

"does it look like a bios update is in order"

Probably not but I guess it wouldn't hurt (as long as you do it correctly)

"if so, what flash utility would i have to use"

The BIOS file & Flash Utility are on the page you linked to above.

"and how"

Here's how I would do it:

1. download the BIOS file (MVP3_D.BIN) & flash utility (AWD763.EXE) & copy them to a formatted floppy
2. boot the system using a WinME boot floppy & select Option 4, minimal boot. If you don't have a WinME boot floppy, download the file to create one here: http://www.bootdisk.com/bootdisk.htm
3. when it stops at the A:\> prompt, remove the WinME boot floppy & insert the floppy created in step 1
4. type AWD763 & press ENTER...this will start the flash utility
5. from there, all you need to do is follow the instructions. Enter the name of the new BIOS file (MVP3_D.BIN) & when asked if you want to backup the old, select yes...name it OLDBIOS.BIN. When asked "OK to Program?", select yes then wait for the process to complete.

jam.. people.. before upgrading the bios i decided to put the 350 cpu back in. i put the jumpers back on 3.5x 2.2v and 95 or 100fsb, then booted once for test. after the initial post display, where it shows :
detecting primary master..none
detecting primary slave..none
detecting secondary master.. none
detecting secondary slave..none

follows a second screen, the one usually showing a chart on thop with the cpu, basemem, extended mem, etc. well on that second page, it's a bunch of jumbled up stuff now. by the cpu it says amd Jk6 instead of amd k6. that's one example. by the memory, it's all blank. and the cursor blinks inside one of the tables. i think this was supposed to say updating escd...success at some point. doesn't get there, it just hangs. ctrl+alt+del causes no reboot. hung. i reset by reset switch like 10 times, same thing happens. does not boot to floppy. what the hell did i do wrong here?

Reset the cmos clear jumper (J14).

Unplug the machine.
Set J14 from 1-2 to 2-3.
Press the power button/switch.
Reset J14 back to 1-2.
Plug it in and boot.


Let us know if it worked.

skip, i did that, and then the system would just stay on the first post phase, not getting on to the second one i described above, the one with the jumbled stuff. after 2 hrs of jumper play, guess what made the difference ?

jumper 3, moved to 1-2. (interleave burst). what is that?

it boots right into windows now so i'm going to try the bios flash. thank you so much.

i really want to confirm, there's no disputing the quality of advice i always get here. i rebooted, with the new cpu, and it sees it as it should, amd k6-2+ 500mhz. thank you all so much.

should I try getting it up to say, 550mhz ? and should I attempt that before, or after i install windows on it?

Perhaps this will add to the confustion...

http://www.cs.umd.edu/class/fall200...

Two multiplier settings you can try to overclock:

100 x 5.5

and

100 x 2.0

What??? 2x??? All CXT core K6-2 processors and all K6-III processors will interpret a 2x multiplier as 6x. The K6-2+ may or may not.

Consider also that 550 or 600Mhz isn't gonna show you a practical performance increase. None of the K6's from AMD made it past 550Mhz; the ceiling of what the K6-2 architecture could reliably handle.

End of game for AMD Socket7 stuff. AMD fixed that with Socket A/Slot A Athlon and Socket A Duron processors.

The k6-2+ was produced up to 600mhz and mine overclocked up to 670 if I remember correctly. Bumping the voltage to 2.2 really helped with stability as these cpu`s were manufactured using same process as the original athlon not the k6-2 series.

ok well i figured out the intel cpu, it's a 200mhz cpu so i guess it's off the wishlist. i had given a pc to a kid, the p5mvp3 mobo with the amd k6-2+ 500 cpu. last night i went and gave him another system, amd duron 1100mhz on a k7som+ mobo. let's just say he's happy. :)

so now i wanna play overclock :)

i think i'm gonna stick to the luckytech mobo, the p5mvp3, and obviously the 500mhz cpu. thing is, aside from setting the multiplier on 2x (so it reads 6x) at 100fsb, there's nothing else i can think of to overclock it over 600mhz. it works at 600, i just tried it that way. i have the voltage at 2.1V right now, which is the normal vcore for it. if i mess with the voltage, will the mhz increase?

Many of the higher clocked K6-2's just would not go much further than stock speeds. Some 500's would give problems at 550Mhz and some 550's just wouldn't go a bit faster. Occasionally, a few would clock up pretty good too. I did have one K6-2/500 running at 6 x 112...forget the motherboard I used. As I recall, it was pretty stable but audio was sometimes garbled.

As for your question, raising vcore will not automatically raise frequency. The motherboard must allow you to go past 100Mhz fsb. Few Socket 7 motherboards had this feature and the ones that did used bios settings. Some settings I recall were like 103/34, 105/34, 110/35, 112/35...that sort of thing.

The processor I spoke of above went to work at 100 x 6 and as of a year ago was still running.

Your mileage may vary...the higher clocked K6-2's were nearly all at the end of their rope. That's why and when the Slot A and Socket A stuff took over; improvement was huge and AMD never looked back.

now that i think about it skip, before i did the bios update in order for the mobo to recognize the k6-2+ 500acz, the bios DID HAVE the option of going over 100. am just now realizing, that option is gone man :) so i guess 600 is where i'll stay.

new problem: i put the fsb jumpers to 100, multiplier to 5, so i'm a 'stock' value of 500mhz. i throw in a win xp cd, and during xp install i encounter a problem. it sees the hd as unpartitioned, and i hit c to create partition, to no avail, because after i enter the disk size and press enter, it goes back to the partitions screen and shows it all as unpartitioned still. what the hell?

i wanna talk about something. people, this little 20inch pc is running WELL. i've already got winxp sp3 on it, and i swear i feel no drag in the system, it's quick as hell. actually installing sp3 may have been slower than on other systems (like an athlon or good duron 1300), but otherwise, it's pretty lean. 16mb vanta on agp, 256mb of pc100 sdram, a 20gig hd, some noname ct4810 soundcard, a realtek pci nic, and no overclock. before installing xp, i tried booting with the fsb at 100 and the multiplier at 2x (6x), and it booted fine, no squeals from anywhere, no revved up fans. i used some good ceramic thermal paste on it. what's up? should i even install the via 4in1 thing in it? i'm afraid it may slow it down :)))))))))))

I think most people would say to install the chipset drivers first, not last after everything else is done. Thats the thing that would concern me about installing them now. If you are happy with what you have maybe don't fix it if it's not broken. Via recommends, the older version for you chip:

considering the amount of old boards, you work with, you may want to download them for future use. It has been over 7 years since there release.

Where did you ever find a bios update for it? Do you have the link?

And watch out with these K62/3 CPU's and running them much above 350Mhz. The little VRM attached to the little heatsink on the bottom of the motherboard will literally unsolder itself it gets so hot! I could only imagine how it's handling a 500mhz CPU.

outlander, damn you're right. i had to look up what a vrm is, honestly all i found is that it's a cap. so i began touching all the caps on the mobo, nothing hot. however, i saw a few mosfet looking transistors screwed up to little heatsinks. there are two down by the cpu, those are COLD due to the airflow from the cpu fan. however, there's one all the way up by the sdram and simm slots, up in the top right corner, that i got scorched on :(/ that thing will light up on fire soon :) help ? can i throw a clip-on fan around it and hook it up to the psu ? it's right next to two caps, they used to be swollen, but i replaced them a while back. as for the p5mvp3 bios and such, i can send you the update/manual if you want it, i got them a few months ago from some ftp i found after hours of searching. either around wim's bios page, or mobokive i believe. here i re-found one of the sources:
