I realised after posting Ingo has V1.5 (STFM booster) fitted in his STE.. It was never intended for use on STE, but is basically same circuit as STE booster. Though of course never had much testing on the STE as wasn't a official upgrade for it.
Could be the reason why he's had instability then.

Current update, Being going overnight and all morning, currently on loop 284.. Really hot today as well..

Floppy case (using as ambient temp) is 29c. GAL 42c, OSC 41.5c. CPU 39c. Buffer IC & PCB temp 37c.


EDIT:

(LOOP 304 13:50pm)
Floppy case (using as ambient temp) is 30c. GAL 42c, OSC 41.5c. CPU 40c. Buffer IC & PCB temp 38c.

Having to put a fan on in the room now as its simply to hot in here now! CPU has run at like 30c for about 4 hours..

So think its safe to say its stable... :hide: .

Current run time is about 17 hours. I am still updating the previous post with results, though temps likely be dropping now anyway..

Those temps are really consistent, which has got to be a good thing.

Yeah, I mean its hottest day ever and CPU has peaked at 40c and still going. Though I heated the CPU to 110c yesterday.. though of course "losses" to the silicon die, even so, the die will have to have raised a fair bit temp wise, maybe 50c... Might try 48Mhz just for the hell of it..

Sounding promising to me , well done.

48mhz, none of this quitting whilst ahead malarky here!

Being an STE newb, is there room for a heatsink on top of the CPU when in situ? and maybe a quiet case fan for some extreme OC action, LOL.

:lol: Well it doesn't work, not suprised really. I guess if I spent another 6 months on it it might be possible, but not worth it.

I don't think it fits under the shielding even. So might have to be a chunk cut out of it. Not got around to looking into it yet.

New super sexy PCBs arrived today :) pictures do not do them justice.
Now to find some time to actually build one up...

Those do look better than the green ones.

I do like the colour of the OSH Park purple though :-)
