GVP G-Force 30/40 problem ...

[LeonardM]

I  to all,
I've a old Amiga 2000 with a GVP G-Force '30/40 inside.
The kickstart version is 3.1 and the chip mem size 1Mb; the GVP mem
size is 4 Mb.

When the workbench starts (1.3 ver) the system seems works but after
a random time (> 5 minutes) my Amiga freeze; I must reboot
the system ... :confused::confused::confused:

If I use the GVP without the mem (only SCSI HD connected to the
G-Force) the system works fine .... It's a memory problem (the gvp mem is
new!) ?

My GVP card is broken ? Can you help me

many thanks
Leonard

Hi save2660,
thanks for you reply !
I've 3 SIMM (4 Mb for each): 2 SIMM from Softhut and the third is original.

Last night I've tested everyone SIMM individually into same memory slot card,
but the system froze; it's possible that the SIMM are bad all ? :confused:
I've executed the software RAM test (each time, with the GVP disk tool) and
the SIMM seems good ...

I think that my jumper settings are ok .... tonight I send you some photos
showing the settings.

regards
Leonard

Yes I've Workbench 1.3 too, but the system freezes the same on.

I've tested with the GVP Install (autoboot, GForce2030-921002.dms ) disk too ...

Hi to all,
'the workbench starts (1.3 ver)' sentence is bad ... sorry

'the workbench starts (3.1 ver)' is ok ; i've workbench 3.1
(with kick 3.1) and workbench 1.3/Gvp install disk (with kick 1.3).

I attach the system's photo showing my settings and more.

Into my GVP Install disk there is not a file named gvpscsi.device,
but only gvpscsi into Expansion dir ...

many thanks
Leonard

Hi,
I've executed the following tests:

a) Kick 3.1 and Workbench3.1 disk (booting with Wb3.1):
--> with HD SCSI:
      original SIMM only -> GVPMemTest ok but the system freeze ...
      SoftHut SIMM1 only -> GVPMemTest ok but the system freeze ...
      SoftHut SIMM2 only -> GVPMemTest ok but the system freeze ...
--> without HD SCSI:
      original SIMM only -> GVPMemTest ok but the system freeze ...
      SoftHut SIMM1 only -> GVPMemTest ok but the system freeze ...
      SoftHut SIMM2 only -> GVPMemTest ok but the system freeze ...

b) Kick 1.3 and GVP install disk  (booting with GVP Install):
--> with HD SCSI:
      original SIMM only -> GVPMemTest ok but the system freeze ...
      SoftHut SIMM1 only -> GVPMemTest ok but the system freeze ...
      SoftHut SIMM2 only -> GVPMemTest ok but the system freeze ...
--> without HD SCSI:
       original SIMM only -> GVPMemTest ok but the system freeze ...
       SoftHut SIMM1 only -> GVPMemTest ok but the system freeze ...
       SoftHut SIMM2 only -> GVPMemTest ok but the system freeze ...

NOTE: I've two SoftHut SIMM; some time the system has not frozen but has rebooted (softaware failure - like guru meditation error msg -)...

The command "version gvpscsi.device" showing 4.15 version

Are my system switch setting ok (look my jpg image) ?

For Cosmos: my gvp card has 5 caps (with the sign 686, 10k, 440);
do you have 5 caps 686, 10k, 440 for me ? If yes I try to buy it ...

thanks
Leonard

Yes I've an 68030 25 MHz .... I've executed some new tests

Kick 1.3, GVP Install disk (for the boot) and without SCSI HD

a) FPU + 68030 + 4 Mb SIMM (jumper settings: J6 open, J5 close,
CN8 2&3 and CN17 2&3 -> are the setting right - to run 68030 at 25MHz - ?) ---> GVPMemTest ok but (after some minutes) GuruMeditation (#00000025.00000000)

b) 68030 + 4 Mb SIMM, without FPU (same above jumper settings) --->
GVPMemTest ok but GuruMeditation! (#00000008.010105F0)

c) 68EC030 + 4 Mb SIMM, without FPU (same above jumper settings: 25MHz) ---> GVPMemTest ok but frozen ...

d) 68EC030 + 4 Mb SIMM, without FPU (jumper settings: J6 close, J5 open,
CN8 1&2 and CN17 1&2&3 - 40 MHz -) ---> GVPMemTest ok but after
some minutes frozen and then GuruMeditation

e) 68EC030 + FPU (without gvp SIMM) 40MHz ---> GVPFpuTest ok but after some minutes the system is rebooted ...

Finally if I run my system without the GVP Combo, all seems works fine !

Some questions:
If I want use Combo without FPU, must open (all pin free) CN16 ?

J13 must be open or close (close = 4 Mb SIMM, open = 1 Mb SIMM) ?

It's difficult for me understand (looking the Combo), which are the right CN pin number (for example CN16 has 3 pin, but which is the pin number 1 ?);
there are photos showing the CN's pin numeration ?

I am really hopeless :confused::confused::confused: ...

I've read the +5 pin voltages (for each pin) with system loaded and on, the results are: about 4.88 V (on pins 1, 2, 3 and 4). Are this bad voltages ?
