Re: Today I overclocked my A3010

I have put a decent heatsink and quiet 5v fan on the cpu now as it was getting warmer than I like after a long period.

Here’s it running Doom+

Re: Today I overclocked my A3010

I haven’t heatsink’ed the ram or the cpu so far, neither seem to get particularly warm and the machine has now done many hours running stuff without issue. I will put heatsinks on them soon enough though, just for peace of mind. I’m hoping to make a quick video of it running Doom+ later. I think it’...

Re: Today I overclocked my A3010

I haven’t so far. The machine has been running ok for the last 3 hours testing zarch, ArcElite, 6502Em and Sf3000 - no problems so far. The Arm250 feels only slightly warm to the touch.

Re: Today I overclocked my A3010

Resistor arrived today, so soldered it and a socket in. Running now with a 74.5mhz oscillator, so that’s 24.83Mhz 462E801D-222C-4436-91B8-1F799AE99ADB.jpeg I can confirm that 6502Em now runs considerably faster than on a stock machine :) Elite is not far off a normal beeb’s speed.

I see you’ve used an smd resistor. I assume using a standard 22ohm axial-lead resistor is ok too?

Yes, it’s uniboot which is causing this error. If I temporarily move !boot then ArmSi loads ok

Re: For Sale: A3020/A4000 & A5000 overclockable RAM

Received the modules last week, now installed and tested, they work great! Installation quite easy in the end but the metal shield definitely has to come off first.

Not tried any overclocking yet, awaiting the resistor

Re: Things I haven’t received yet...

I once bought a quite valuable retro item from Poland - it sat in customs at Heathrow for two months before being released. The tracking simply said it had left the country of origin. I had to make a number of calls to various agencies to even find out it was sitting in the UK.

Happy with that Daniel, and you’re much handier than me at repairing stuff! If it turns out you can’t do the collection then I’d be happy to do it :)

Re: A number of Archimedes units and software available

I’d be interested in collecting them and then passing them onto other stardot users at an abug or other meet up. I’ve personally been looking for an Arm3 A3000 for ages!

I’m only across in York so collection could be pretty straight forward.

Re: Open source A3020 RAM

When it comes to overclocking then, is it a matter of changing an oscillator on the motherboard?
