WarpEngine 68060 @80mhz!

[fitzsteve]

I saw this posted on EAB:

I need to reg with A1k.org to find out more, but OMG, I need this in my life

 

[mjnurney]

most Apollos with a late 68060 will hot 75 / 80 mhz steve.

one chap has 100mhz...

i wonder how the adaptor works?

[fitzsteve]

Yeah but Apollo SCSI Sux, the WE is awesome! I'd love to have it 060 @ 80mhz

 

[mjnurney]

i cant argue on that bud

 

[baderman]

I'm glad I haven't sell my WE. Now it's time to make this great mod!

 

[roy_bates]

yeah,seen it.its is awesome.

 

[SkydivinGirl]

OMG! I want two of those adapters to go with my two Warp Engines! Very nice.

Cool!

I hope they decide to build it and sell it :roll: and that it won't be very difficult to install

I have a WE looking forward for it

 

[lostrego]

Nice hardware, once seen this It musn't be very difficult to make a similar board for overclocking existing 060 accelerators.

I'd love to see a Cyberstorm 060 mk I, II or III working happy at their stock 50mhz speed thus no problems with the SCSI not stress or heat to the components either and with the 060 pushed at 80Mhz, it would be nice.

 

[Miru]

Nice!

Time to keep the WE

This 040-060 adapter was designed by Mozart based the Motorola (Freescale) 060 manual. It requires additional code to disable the 060 FPU at startup (unless you use an EC060). The extra FPU code is currently implemented by a Zorro2 board but it's also possible to build custom ROMs with the extra code. More info is available here:

@SpeedGeek: Hey, with one of these you could reach 100MHz with your modded A3640 as this adapter seems to took the master Clock (or whatever it is called) directly to feed the 060 (i.e. 040 CPU Clock x 2) .

It would be awesome to see an A3640 working with a 100MHz 060 on it, perhaps It'll need some severe overvolting. :-o

its more likely its running in 1 on 1 to the master clock on the card,an 040 is the clock divided by two.

 

[lostrego]

Yep I expressed myself wrong, I meant that the CPU core runs at 1/2 the master clock on 040 but in 1 to 1 on 060.

I told that because the SpeedGeek's modded A3640 runs at 50Mzh as 040 CPU core freq so I assume the master clock is 100Mhz here.

It's really nice to see those tremendous overclocking, but obviously all that hackery just drains hardware's lifetime.

 

[lostrego]

@Phantom: The good part of this adapter is that the only overclocked part is the 060 CPU itself , the rest of the accelerator (memory bus, logic chips etc...) still run at stock speeds (40Mhz for the Warpengine) son you'll only risk the 060 chip. Is not like doing extreme overclocking to say a 060 Cyberstorm MKII/III where you risk the whole board as all the chips and buses run 1 to 1 to CPU freqs.

Though the rev6. 060 should do ok at 80Mhz with proper cooling, in case something goes wrong is just a matter of replacing it, which is a quite easy task and not that rare/expensive part as a whole accelerator.

@lostrego

1) AFAIK you need a late Rev. (or late mask set) 060 + 3.5 Volt reg. to overclock an 060 to 100 MHz. This bumps up the price tag quite a lot.

2) It is unknown if the 060 was operating in 1/2 CLK bus mode or the accelerator logic was 100 MHz capable on the few cards supporting 100 MHz.

3) Mozart has not been able to use his adapter with a state machine modded A3640. Possibly because his adapter does not adjust for the skew differences between CLK doublers and CLK dividers.

4) I don't have a high degree of confidence the 100 MHz CLK can be synced precisely enough to the mobo 25 MHz CLK for reliable operation. (With the 040 it's only used internally but not for latching data or write cycle data hold timing as with the 060).

 

[lostrego]

Well was a nice coulda shoulda thought, if possible that could be definitively the fastest A3640 ever seen by mankind.

For what I know tho only amiga acceleartors capable of doing 100Mhz are the Apollos. as the bus freq can be switched. the bus freq must be switched to 1/2 of the main freq (If I don't understood it wrong a 060 is capable of operating in 1/1, 1/2 and 1/4 bus modes).

An yep AFAIK not all rev. 6 060 handle ok 100Mhz overclock, only the latest batches from freescale.

 

[roy_bates]

none of my three 060 cards that run at 100mhz are overvolted,they all run on 3.3 volts.
not that makes any difference.

as speedgeek says theres no gaurantee the bus or even memory controller could handle those sort of speeds,but it would be really nice to find out.
but i wouldnt recommend it,unless you really want to
