Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

V5.07.00RC1 now available - getting closer  

http://geoffg.net/Downloads/Maximite/CMM2_Beta.zip

This update will erase all previous options and force re-initialisation

Minor changes:

Overclocking to 504MHz is now enabled with OPTION OVERCLOCK ON
and disabled with OPTION OVERCLOCK OFF

In addition you can also force the CMM2 to run at 400MHZ irrespective of which chip is installed using OPTION BASELINE ON
This is disabled with OPTION BASELINE OFF

Option overclock and option baseline are mutually exclusive and setting one will cancel the other as required

Not working as intended on my 400 MHz:

Looks like the OFF's are non-functional and the mutual-exclusiveness is non-existent

Sorry, Tom

I suppose it's possible caching means I still haven't got the correct version installed, but I don't think so, do you have an MD5 ?

I'll try and find time to play more later.

Best wishes,

Something very wrong - Option Reset isn't clearing the options
I thought I'd found a way of reading the options before setting the clocks but something isn't right - don't waste any time on it

@thwill
Are you actually running a 400Mhz chip at 504Mhz? Water cooling?

I ask, since mine is also 400Mhz. I normally would never have tried that... 480 maybe, but 504....


Edit: tried it, it works. Gonna run some reliability tests tomorrow...

Hi @Volhout,

I believe 504 MHz is the only overclocking game in town, or at least the only one that @matherp has sanctioned for both the 400 & 480 MHz CMM2 and he hasn't suggested any additional cooling. However I'm only doing this for the purposes of testing the Release Candidate, after that I will return to 400 MHz, more than fast enough, or if it isn't then I can switch to C and get a > 10x performance boost.

Best wishes,

Tom

I've been running at 504 for some time now...months...no issues...yet. Warm time is here though...so...we'll see.

No: This was always a temporary solution and is generally a bad idea because it limits pin use for connected devices.

As there has also been a requirement to run 480MHz devices at 400MHz for compatibility testing I needed to bite the bullet and try and find a mechanism that would allow options to be read before the main clocks are set up. This version should do that if I have finally ironed out the wrinkles - Tom?

Sorry Peter, I should have some time after lunch to test.

Hi Peter,

- Overclock/Baseline/Reset options all seem to be working with latest RC1 download.
- All my unit-tests are working with RC1 (except known issue with Static variables).
- Z-MIM smoke-test passed with RC1.
- Smoke-tests of Bill and my new Scott Adams Adventure Interpreter [Coming Soon] passed with RC1.
- Smoke-tests of all programs on The Welcome Tape passed with RC1
    - though I did find a couple of what I believe were pre-existing issues with Mandelbrot Explorer (https://github.com/thwill1000/cmm2-welcome/issues). I am not proposing to do anything about these, but if @Sasquatch is still active on TBS or someone else wants to take a look then I am happy to update The Welcome Tape with their efforts.

So, looks good to me, thanks again Peter.

Best wishes,

Tom

Hi Peter,

the new way to set overclocking by software is a great invention!
Even better my good old GAME OF LIFE still works flawlessly (6ms/generation for demo1).

An observation: in very early versions of the CMM2 firmware, I noticed a huge difference in execution time between RAM and ROM mode (ca. 10%). This difference has disappeared for some time. Is there still a difference between RAM and ROM mode at all?

MM.INFO(CPUSPEED) should be updated in the manual.

Thanks a lot!

Best regards
Michael

I'm very happy with what we've got, but I wonder if there is any merit in these new options being set via:

OPTION CPUSPEED 400|480|504|BASELINE|DEFAULT|OVERCLOCK


Where:
- BASELINE is equivalent to 400
- OVERCLOCK is equivalent to 504
- DEFAULT is equivalent to 400 or 480 depending on the processor
- 480 is not valid on the 400 processor

And then replacing or supplementing MM.INFO(CPUSPEED) with MM.INFO(OPTION CPUSPEED) which would return the numeric value rather than the string equivalent.

If nothing else this would leave more maneuvering room should other speed options become available in the future.

Best wishes,

Tom
