HSF = heatsink and fan (for the CPU).
You might want to test your RAM modules separately to isolate the faulty one, if there is a faulty module.
That motherboard has a LOT of jumpers - I would be certain that all were set correctly and that the BIOS settings (especially those involving RAM and CPU voltage) were correct.
I would also load those motherboard drivers.

EP-MVP3G2 Rev 1.0 (8/6/01 BIOS) -- K6-2+ 550ACZ @ 618MHz (103MHz FSB) 640MB PC100
EP-MVP3G5 Rev1.4 (8/6/01 BIOS) -- K6III+ 500ANZ @ various MHz
EP-MVP3G5 Rev1.4 (8/6/01 BIOS) -- K6III+ 500ANZ @ various MHz
So, good morning...
I ran Memtest86+ the whole night with both 128MB ram modules and the AMD K6-2+ 550MHz. It ran 11 times, but no errors.
Then I used only 1 RAM-Module at a time, nothing changes, still the same errors in windows xp with the K6-2+ .
Ran the pc with only the minimum devices...
Another symptom: I'm using this computer for the BOINC-project (like SETI@home ...). When downloading files with the K6-2+, all downloaded files have checksum errors, using the AMD K6-2, everythings fine.
So, now I'M convinced its the cpu. If anybody else wants to give it a try. I'm happy to send the cpu to you whereever you live. Just talk to me...

Something doesn't make sense here.
All you are doing is swapping CPU's, and changing VCore to suit...nothing else.
If Memtest passes overnight (as yours has), then your CPU/Memory sub-system is completely functional.
Are you sure your HDD is not failing in some strange way...or perhaps the 40-pin ribbon cable...or some other strange IDE port damage?

I just dont get it, with AMD K6-2 everythings perfect!KachiWachi wrote:Something doesn't make sense here.

With AMD K6-2+, data corruption, hangs up, grahical errors, ...
So why can't it be the CPU? I thought Memtest is testing the Memory, how can you tell that the cpu/memory-subsystem is ok?
Obviously, i'm stuck...
Maybe it helps, if someone has the same board AND cpu (HOT-591P and AMD K6-2+ 550) can tell me all the configs of all jumpers, BIOS settings, and so on...

If you want to send the cpu to me in the UK I can test it out for you in a number of different socket7 motherboards. However it might be just as cheap to buy another socket7 board in Germany such as a Asus P5A (rev1.04)or a Gigabyte GA-5AX (rev 5.2) for ATX or if your board is an AT you could try a FIC VA503+ or a Asus P5A-B (rev 1.04). Why don't you check out your local e-bay site for socket 7 boards?

Memtest is testing the RAM modules, the CPU cache (L1 and L2) and the motherboard L2 cache (which becomes the L3 cache with the K6-2+). I agree with Kachi - memtest running 11 error-free passes implies that the CPU and RAM and mobo cache are OK.
I'll be back.

I had an AT rig set up with a Soyo board that used to give me all sorts of grief. Just changing from an AT power supply to an ATX power supply sorted out all of the issues for me. This AT supply worked fine with a normal K6-2 cpu but would not work very well with a K6+. It would be easy to rig up an ATX power supply to your set up to see if it works.

So, any idea why that made a difference? Does the K6+ need more power, or "different" power?Stedman5040 wrote:I had an AT rig set up with a Soyo board that used to give me all sorts of grief.

Thought this whole story will be much easier, K6-2 out, K6-2+ in, just like I always did with my 3 computers...

Just to check the motherboard's jumpers:
(Looking down on the motherboard with the AT/ATX power connector in the upper right corner)
JP1 should have a jumper only on pins 11 and 12 (be sure that pins 1 and 2 are not jumpered).
JA26 should have the first two pins jumpered
JA27 should have the last two pins jumpered
JP9 should not have any jumpers
JA25 should have the last 2 pins jumpered
J19 has no jumpers for 2.0V, while jumper on pins 1A and 1B is for 2.1V.
JP8 should have a jumper on pins 1 and 2 for AT power supply connection
JP2 should have a jumper on pins 1 and 2 (the Clear CMOS jumper - a jumper on pins 2 and 3 would clear the CMOS and a jumper on pins 1 and 2 would enable the currently installed BIOS to run)
Be sure the AT power connector is plugged in correctly.
What is the power supply's power rating?( 150W, 200W...)
In the BIOS, turn off all BIOS shadowing. Be sure to enable CPU Internal Cache and External cache.
CPU Core Voltage in BIOS not set to AUTO.
For the time being, set both IDE Prefetch Mode and IDE HDD Block Mode to DISABLE.
IDE Primary Master PIO and IDE Primary UDMA set to AUTO.
Have you checked the HDD?
Now install the K6-2+, set the voltage jumpers to either 2.0 or 2.1, and re-install WinXP.

Aside from the CPU's themselves, the only other difference there is outside between the K6-2 and K6-2+ is the voltage settings. Maybe the voltage regulators on the motherboard don't work as "clean" at the lower voltage required. Try running the K6+ CPU at 2.2 volts, which is still a safe voltage for the chip, and see if the system is more stable. Another thing to try is to underclock the CPU. It does sound very strange.
OK, I'll give it a try.sylvan2626 wrote:Just to check the motherboard's jumpers:

You tell me not to set the CPU Core Voltage in BIOS to Auto - before installing the K6-2+? But on the mobo the jumper is set on Auto, as long as the K6-2 is installed. - And to what voltage should I set it before installing the K6+, to the one I want to use afterwards? lets say 2.1V?
My AT Power supply has 200W.
I've checked the HDD with Scandisk and HDTune 2.53.
..and re-install WinXP - will be the 6th time...
