is it 800Mhz or 1.8 Ghz ?

just picked up an m6805... great laptop. one thing still confusing me is the processor speed. i've read thru a number of threads before buying, and understand it backs down to 800 Mhz on battery. however, while it is on a/c power, it still periodically reports 800 Mhz (sometimes it is 1.8 Ghz). i also see 800 MHz reported in sandra when this happens.

any help for this newbie would be appreciated.

I have not seen that happen yet. Are you sure that when it reads 800mhz that it has a good power connection? Does it show that it is plugged in when this happens? You can see how to eliminate the 800mhz problem all together here in this thread.

ok... just tried it - FYI, it won't install on XP [ ]

 

has anyone else tried this "power now" app from AMD? It says it's for win2k not XP. how does it work? will it let switch on the fly between 800mhz and 1.8ghz or will it lock me in to 1.8ghz regardless of weather i'm on AC or battery? guess i should install it and see eh? [ ]

Doh! Got it. I read "install then right click" so I was trying to instal it first... truthfully, I had no idea you could set the properties on an exe file in XP to install it in a "compatibility" mode... and I do this for a living.

for anybody else this is new to as well:

here's an interesting item...

have not installed powernow app yet. was monitoring cpu speed from system properties, and it was consistent at 1.8 Ghz. executed sandra again (v2004.2.9.104) to check cpu & bios info, and it immediately reported 800 Mhz. went and checked system properties again, and sure enuf, it was now reporting 800 Mhz. exited sandra, and after a few minutes, all was normal and back to 1.8 Ghz.

patient: "doctor... i don't know what's wrong, but it hurts when i do this..."

doctor: "well... quit doing that."

 

more info...

installed powernow. also found a tool (wcpuclk - real time clock checker) that monitors clock frequency. after powernow install, i set performance for "plugged in" and "run on batteries" to high performance.

now, when i'm on batteries, clock stays at 1.8 Ghz. when on a/c, it drops to 800 Mhz unless i execute an app... then it jumps up to 1.6-1.8 Ghz.

not sure of the technical term, but it seems to be working in a power saver mode while on a/c (clocking down to 800 Mhz when no activity is occurring) even though it's set tohigh performance. would be nice if amd had a current winxp version of powernow.

here are sandra results while running on a/c... numbers are similiar on batteries. anyone have similiar benchmarks, or know where some are posted so i can compare ??

thanks for bearing with me while i learn this stuff. below are my results from sandra...

i think i figured it out... just don't understand why...

with the amd powernow app installed, and performance set to "high performance mode", i was still seeing the system clock drop from 1.8 Ghz to 800 Mhz (on both a/c and battery).

i then set the power scheme to "always on", and it jumped back to 1.8 Ghz and stayed there (on both a/c and battery).

problem solved (i think). thanks to all that helped.

 

why would you want it to run at 1.8 on battery? I'm trying to decide if I want to lock it at 1.8 Will battery life be drastically hurt???

 

Alright, I feel dumb. I've installed the PowerNow program, but where do I go to set the different power modes? I don't see it in the Power Properties area...

Thanks.[ ]


eMachines 6805, and enjoying it thoroughly!

 

i cant get my M6809 to run at full on battery even with the powernow app installed im reluctant to install the new CPU driver anyone found a solution to this yet?

so your saying i wont beable to get this thing to run at 2Ghz while on battery or is there another way? Is the Bios the problem? Newer version maybe

 

Why will it not work on 6809,s that really erks me. i'm going to call emachines. it should be preloaded. it is on all the xp chip models.[ ]
