Question about E125

[trenmost]

Hi!

I bought an e125 with amd e450, and im very happy with it! I have some issues though:

1: CPU-Z and other apps tell me that i have 1066mhz ram, instead of 1333. I tried to check what's written on the module itself, but there is a sticker on it that covers it, so i cant read it...is it possible that the ram got downclocked somehow? how do i turn it to 1333?

2: How do i enable the turbo core function (i have the amd e-450 version)

3: I installed the latest hotkey integration features, but it doesnt seem to work! the install was successful, but when i change the volume, there is no display for the currrent sound volume, and i cant turn the wifi off trough Fn+F9 (nor with F9)

4:The bluetooth driver i installed tells me that it didnt found any BT devices. BT is enabled in the BIOS

None of these are breaking issues, but if anyone knows how to address them, i would like to know!

Finally, not an issue but: what does the fn + Space combination do? there is a light like icon on it

Hi trenmost,

For 4, you also need to install Power releated drivers and wireless device driver from lenovo:-

For 5, you first need to enable Bluetooth radio via Fn+F9. Once enabled, WIn 7 will automatically install its driver.

I think the E450 might just be limited to 1066MHz for RAM?

[trenmost]

no, its one of the key improvements of e450 (over e350) to support these kind of rams.

[trenmost]

The turbo core problem is solved, i found out that its enabled, and the GPU rescales its performance depending on the load.

i installed the hotkey features successfully, thanks for the help.

could anyone tell me that the Fn + Space combination does on this machine? when i press it nothing happens.

if you would have all the drivers installed, you would see that the space+fn just shows a cut-light icon...so it does nothing, i guess the keyboard is common to other models which have illuminated keyboard...or thinklight option

about the ddr3 frequency, i see the same issue and hope lenovo will fix it soon with a BIOS update...

how did you see turbo-core option active?!

there is no way to make the memory work as advertised to 1333mhz speed, lacking a bios support for it. this is the answer i got from lenovo support via local ibm warranty service:

"I've received the response that the latest BIOS (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS019439 ) and the Power Manager (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS014924 ) set to Maximum Performance are required to get the most out of your system and that it is currently working as designed."

so product advertised as 1333Mhz, 1333mhz memory supported, 1333mhz supported by architecture (cpu-memory controller etc.), but working at 1066mhz only.

i am thinking to return this e325 product as not being according to specifications!
