Overclocking the Derringer Accelerator.. which 68030 is best?

[delshay]

Is there a particular version of the 68030 chip that is better than others for overclocking (e.g. the 68060 has certain masks that are more suitable for overclocking).  I want to upgrade my 40mhz Derringer to at least 50mhz; however, I figured why not try to get a few extra mhz's in the process.  I have searched for old threads as I vaguely remember someone overclocking to 52-56mhz (my memory is a bit hazy about the details).

Also, would 50ns ram make the process of overclocking more stable and/or feasible?  I'd appreciate any help.

50ns does help with overclocking but iv found that not all 50ns simms overclocked the same. all will give some inprovment over 60ns how much also depends on the card chipset.

here iv overclocked a Blizzard PPC with 80Mhz bus, but only 1 set of 128 simm modules will allow this kind of speed. my other 50ns simm modules will only allow around 75Mhz bus.

just for the record the Blizzard PPC will go all the way to 83Mhz bus (tops),but at this speed this PCI interface refuse to work,this test was done with AGA ( no SCSI ).

Keep in mind that actually buying a brand-new 030 CPU from Freescale will cost a hilarious amount of money. Also keep in mind that 50 mhz 030s are very, very rare in the used market.

parts are not that hard to find,you just have to have the right contacts,i have here some rare parts which was not that hard to find example PPC 604 375Mhz.
