Sonnet Quaddoubler

[Xand]

Hello all.
I unsoldered the '040 on my BlizzardPPC, soldered in a socket, and put in a QuadDoubler. It's the 'B' version. According to Sysinfo, it's running at 57.10 MHZ.

Benchmarks -
Sysinfo:
    Dhrystones - 36154
    Mips              - 37.73
    MFlops          - 9.58

SysSpeed:
    Mips              - 36.15
    MFlops          - 13.72

It's about twice as fast as an '040 4000. Fusion 3.2 is almost usable with it.

Just for fun, here are the numbers from SysSpeed for my 240MHZ 603e:
    Mips -     295.14
    MFlops - 182.77

The '040 I replaced was a 25mhz version. I don't really know why it's running at 57mhz. They cost about 99USD, 59.33GBP, or 84.73 euros.

I have one on a 3640  in my 3000 also. It works well.

Well, in my case, the point is that I already had the BPPC and the 060 mod is a lot more than I wanted to try with a rare board. This was reasonably safe and gave me 2X the speed.


@odin

 They probably are overclocked, the highest clock speed I can find on the Motorola site for an 040 is 40mhz.

@Cyberus
I haven't had any compatibility problems yet.

@-D-
No problem.
