Hi,

I've got a toshia satilite laptop with a AMD e-450, I was wonderingif anyone has over clocked this laptop or knows if its safe to do so?

Toshiba Satellite L750D-14R with AMD E-450 APU with Radeon HD Graphics 1.65GHz.

Thanks

yes it can, but i hope you red the whole thing

if your cooling sucks like mine (60C ideal T - 71C stress T) then don't go over 2.20Ghz for general/multimedia use and 1.80Ghz for light gaming,

anyway post some T figures so i can get an idea about your cooling

good for you chap mine can do 3.34Ghz!, but it's an empty overclock, it has no real world performance increase, do some benches and see if overclocking did improve your score

Of course it does.

You're probably doing it wrong. In my case, I have to set the P1 State multiplier to 1.25, TOGETHER with the P0 State, which is the turbo. This way, anytime there is load on the CPU, it will always be at 3.2ghz

If you want to see improved performance, overclock the both the P0 and P1 states to the same clock.

there is only a GPU turbo on the E - 450 (500Mhz > 600Mhz ) also, P0 is the CPU's max Clock/turbo (C - 60) so whenever you do a stress test your APU will always defualt to P0 state, regardless of what the P1 state is, anyway, can you post a screen showing a benchmark score before and after overclocking?

That's where you are wrong.

If you used CPU-Z to monitor the CPU clock under utilization, you would see that the P0 Turbo state is very conservative, and isn't 100% consistent and isn't on all the time, and will at times revert to the P1 state.

That's why you NEED to overclock the P1 state, because that way, even when turbo is not working, the CPU will always be at the desired clock speed, expect when idle.

forget what P state you use, your CPU in any stress test, (not a basic/brief 100% CPU load) will always default to P0,

anyway, kindly post a benchmark score of your APU, before and after overclocking, it could be that brazostweaker is working for you

I read the whole thing, but alot of it went over my head tbh

So I don't really get what you mean by empty overclock that you have been on about in this thread, but at a stretch I'd say it wouldn't change the clock speed really, only what came up on the program.

I want to overclock specially for gaming.

By T figures I'm guessing you mean temp, in which case it will be monday before i can get a gaming (company of heros) temp reading.

Thanks for the help so far

I've attached the temp log

CT-Log 2012-11-12 18-24-11.csv 10k .csv file


It shows the temp at 57 at 100 load.

Thats playing Company of Heros for a bit in a heated room

What went over my head is, does that software actually overclock it? Just asking because you mentioned empty overclock a couple of times.

Your cooling is great (for a laptop), try BrazosTweaker and see if your can overclock the thing, but don't let your APU go over 80C if you don't want to kiss it goodbye anytime soon, you "should" be fine with 2.60Ghz OC

anyway, no matter what, don't overclock your APU to the max "3.34Ghz" so you can avoid what happened to me..

I wouldn't have tried going over 2.0Ghz really, its rated at 2.4 according to can I run it.

the site has info on how to use the program, check it out, also 2.4Ghz my ass..the CPU is pathetically weak..

So I should just change the Mult = 33 divided by -> lines to 1 on each of the P0-P2 tabs to get a cpu speed of 3.3GHz?

So to get 2.0GHz I go for 1.65?

I'm just trying to be very careful and not kill my laptop

so sorry for all the questions

just work with P0

Mult = 33 divided by

2.00 you get 1650Mhz (default APU speed)
1.75 you get 1885Mhz
1.50 you get 2200Mhz
1.25 you get 2640Mhz

do some benchmarks to see if brazostweaker is working for you,

do not decrease to 1.00 (3300Mhz)!
