I've got a dual 1 GHz AlphaServer ES47, and I bought a dual 1.15 GHz module (part number 54-30252-KR). When installed, the new CPU module still just runs at 1 GHz.

I removed the CPU heatsinks from the old and new modules and discovered that all four EV7 CPUs are actually marked as "1150 MHz".

I've been through about every MBM> command and can't find anything that looks like it could configure the CPU frequency.

Running the UNIX command 'strings' on the ES47 firmware image, I see things that indicate that there are options somewhere for controlling the CPU frequency.

This string indicates that there's a "CMM" menu with relevant options:

> z - connect to EV7 com port
> quiet_mode enabled
> f - set frequency
> a - send a test alert
> EV7 COM%d port passthru mode on CPU%d, use <esc><esc>CMM to return.
> [...]
> CMM>
> [...]
> CMM Commands:
> [...]
> f <ev7 freq in Mhz> [ip ratio [io ratio [zbox ratio]]]

Also:

> /tyCo/%d
> /tyCo/1
> Starting PPP to CMM %d, IP: %s, line: %s

and

> cmm_serial_baud

So there appears to be some way of connecting to the CMM via a serial console?

> MBM> show cmm_serial_baud
> cmm_serial_baud 192000

Additionally, there are these strings:

> EV7 clock frequency set to %d MHz on next power cycle.

> [...]
> Setting EV7 freqency to %d MHz on the next power-on

Does anyone know how to configure the CPU frequency or to enter the "CMM>" menu?

Thanks,
Matt

Since you can get to the MBM prompt from SRM with <esc> <esc> MBM
you could try <esc> <esc> CMM

For any serial connection you will have to find the right IP address
using SHOW NET from the MBM prompt and telnet to it on port 23

Is it worth it for a 15% speed increase?

Phil
