Get error on Memtest86 - How to solve the issue?

[persson121]

Hi.

I have Windows 95 and i love it. I need to get my computer back to action agin. I will only make it work beacuse i will only play good old awsome games on it.

But the problem is memtest.

I have NEW memory but i get the same old error if i use an old memory. I only this error. ONLY THIS.

Everything works on it. I got everything orginal too. Internet works. But internet Explorer 3 is not good to surf with.

I can run the the computer, but it VERY unstable. If i install like Half-life, i get bluescreen.

I think it has to be with the bios, but i cannot find the update drivers.

My computer:

HP Hewlett Vectra packard VE 5/200 MMX SERIES 4

BIOS:

Pheonix

Please! Help me

If new memory sticks (where do one get new PC100 SDRAM nowadays?) gives the same error as the old ones, and you've cleaned the slots thorougly with a soft brush before inserting the new sticks, chances are the motherboard is no good anymore... consider replacing it. I'm sorry.

You can get SDRAM 100-pin from china. Aliexpress.com

Hmmm... is that a 66mhz FSB? I believe it is (had two of those old Vectras - gone now). You'll probably need PC100 compatible for PC66... Not all PC100 are backwards compatible, whereas most PC133 are backwards compatible to PC100 (and sometimes PC66). You'll get those kind of errors if they are "wrong".

Good luck...

What do you mean?

I have 200 mhz.

I have 200 mhz.

Your Processor is 200 MHz, but your FSB (Front Side Bus) is probably 66 MHz. As of now, there are two possibilities. You are using the wrong speed RAM, or your motherboard is busted. You will need PC66 or PC100 RAM. What speed RAM are you using?

[dencorso]

No. I've googled around and I still think his mobo's FSB is 100MHz... that's why I've mentioned PC100 SDRAM.

I had a similar situation a couple of years ago and the problem turned out to be the motherboard not the RAM.

I don't know what you paid for the new stick of RAM but you can probably pick up a working Pentium III computer for as little as $1. Windows 95 can live quite happily on it without going overboard on the CPU speed.

Mmmm... My old ones were Vectra VL's...

Google this exactly as you see it -

"vectra ve 5/xxx series 4" manual

These are the specific manuals.

In the Technical Reference Manual it states

The main memory controller supports up to 384 MB of EDO, FPM or

SDRAM double interline memory modules (DIMMs). The HP Vectra VE 5/

xxx Series 4 PC supports three modules of SDRAM (synchronous dynamic

random access memory). With the 64 MB module from HP, this gives a

maximum total capacity of 192 MB.

In the case of 66 MHz PL bus operation, memory accesses have a timing

pattern of 6-1-1-1 for a page-hit. This degrades to 10-1-1-1 for a page-miss.

The Pentium processor is packaged in a pin-grid-array (PGA), and is

seated on the system board in a zero-insertion-force (ZIF) socket 7. Only

upgrades that are pin compatible with the original processor, manufactured

by Intel, are supported.

P54CS chips working at 166 and 200 MHz require between 3.45 and 3.60 V.

A VRE voltage regulator, integrated on the system board, actively derives

the voltage from the 3.3 V, 5 V and 0 V outlets of the power supply.

There is a 14.318 MHz crystal oscillator on the system board. This frequency

is multiplied to 66 MHz by a phase locked loop. This is further scaled by an

internal clock multiplier within the processor. For example, the 200 MHz

processor multiplies the 66 MHz system clock by three.

Switches

1-4 - Bus frequencies (see the table on page 24) -

5, 6 Open Not used Open

The Switches 1-4 in the Table mentioned only speak of 66mhz FSB, so either PC66 or compatible PC100... CPU-World bears this out as well for a Pentium 200mhz...

Ummm.... I supplied info about the Service Manual, the CPU, and the fact that PROBABLY PC100 will work fine, PROVIDING they are compatible. That "link" is specifically to an MT-version of the PC. The OP never said it was that, the poster giving the link assumed that.

Thanks for providing a quote from a known linked-to PDF though...

A big list of Manuals, etc.

I think MT stands for Mini Tower as opposed to small form factor. The motherboard specs ought to be the same.
