68030 not running at 25Mhz

[AmmoJammo]

did you get it, did you get it, did you get it, did you get it?

[Lurch]

Went to the mailbox nothing there :-( Today today... come on :-)

Was looking at another accelerator a derringer through google and it has the similar setup of halving the speed.

Might get a 80Mhz and drop it in should get 40Mhz... hmmm...

[Lurch]

Will get those photos done tonight of the VXL-30 :-)

[AmmoJammo]

if you're going to try a 80Mhz crystal, take the FPU out first :p

[Lurch]

So put the 40Mhz crystal in and CPU and the grand total came to 13.4Mhz :-) LOL

Back to the drawing board.

[AmmoJammo]

ah, so that was new crystal, and new CPU?

interesting...

[Lurch]

Yep

40Mhz Crystal + 40Mhz CPU = 13.4Mhz
40Mhz Crystal + 20Mhz CPU = 13.4Mhz
40Mhz Crystal + 25Mhz CPU = 13.4Mhz

LOL

Jumpers are set to the following

JP1 OFF = 68030

JP2 ON
JP3 OFF
JP4 ON = 4MB load high

JP5 OFF =  Cache on
JP6 OFF = MMU on

Jumper SP1 unsure what that does, if I move it to 1-2 Amiga wont boot 2-3 it does.

Can't see anything else on the board I can change. So busy translating the manual at the moment.

[AmmoJammo]

try removing the FPU?

[Lurch]

Hmm, will give it a shot. :-)

[AmmoJammo]

also, do you have your 68000 in the accelerator? maybe try with/without that?

[AmmoJammo]

and while your amiga is apart (like it was ever together) could you please take a good quality, highish resolution pic of the accelerator? just from the top, straight down

[Lurch]

Would love to remove the 68k but it's soldered to the board, a shame as I wanted to have the 68010 as a fall back.

Removing the FPU didn't help, so will try and take a nice photo for you. Although my camera is not the best :-)

Hopefully the link will work. :-)

Does it run without the crystal (!).

[Jiffy]

Have you used addmem to activate the 32 bit ram on your turboboard?

According to TBBOAH ram on this card is not autoconfigured. No (active) 32 bit ram will result in terrible performance.

[AmmoJammo]

It wont result in the cpu running at 13.4mhz though :/ what does it do it "fall back" mode?
