Will overclocking damage Neo AES?

MCF 76 · Mar 8, 2010

Hey guys, I wanted to see if doing the overclocking mod to my Neo AES with toggle switch will damage it over time if used alot?

Xian Xi · Mar 8, 2010

Only if you overclock it at a ridiculous speed you would most likely burn out the CPU more than anything. Stock is 12mhz so try not to go crazy like past 18mhz.

I usually just do a 14.3 or 15mhz, highest I went was 16mhz.

I saw a video of an overclocked aes ... it stopped the slowdown in fatel fury 2 but had a bit of graphics corruption ... is it possible to get rid of the slowdown without the corruption?

Not possible with the old system. The corruption is from the ports that write to the gfx ram not keeping up.

Also forgot to mention that I think it's also a programming problem. When I overclocked my MVS at 16mhz I never had any glitches playing MSX, MS3, MS4 and MS5. I only had problems on certain games like Captain Tomaday, FF, FF2, Blazing Star. But of course that's at 16mhz.

I think a comfortable speed would be about 14mhz or maybe even 13.5mhz just for a little boost.

Xian, do all games play at "normal" speed (as opposed to 133% speed with 16 mhz, etc.) when overclocked?

Xian Xi · Mar 17, 2010

yup, all play at normal speed. The overclocking just helps with the slowdown.

It's the same thing. Programmed for fast VRAM write means glitches with o/c. Ironically, slowing down 68k writes to VRAM would fix it. Or some hardware addition that inserts wait states when it's trying to access LSPC, I don't know.

How old of system do you think Xian? mine's a 27233 serial#. I was gonna start with the 14.3mhz speed crystal first then maybe go up to a 16mhz if the 14.3 isn't fast enough for my taste.

By old I meant the Neo in general. 14.3 is a better starting point. At 16mhz any game other than Metal Slugs will have gfx corruption.

Ok gotcha, I'm having this mod done mainly for Slug 2.

X, you said you overclocked your mvs at 16mhz. Did you try running shock troopers 2?

Slug 2 didn't make much difference but it did make some.

I did. At 16mhz there were some gfx corruption but the slowdown was minimal, at 14.3mhz the slowdown was also minimal but I can't remember if there was any gfx corruption, I don't think there was any.

Yea dude, because the slow down in ST2 is ridiculous. Its a shame too, because its such a good game.

Thanks for all the info, hell if speeds Slug 2 even the slightest bit that will be awesome imo :buttrock:
