Overclocking amd A4-5000 levovo x140e

Hi :hi2:,

i am french so sorry for my poor language.

I have bought a lenovo x140e with a A4-5000

i put a 2*4Go corsair 1600Mz and a hybrid ssd HDD 1To

so i would like to knows if it s possible to overclock this or to knows the pll of this netbook

for the CPU:
=>Nothing in the bios
=>pscheck not work,

for the GPU:
msi AB not work,
powerstrip not work
asus gpu tweak tool not work
TRIXX not work

i tri but no result for this moment but i will find.


If you have any idea i am ok

 

Your probably can't OC it because of BIOS limitations and this is a budget AMD processor at the end of the day.. So there will be no solution

 

not sur guy

for exemple i had a a10-4600m and a10-5750 and a8-5550m lol and with overdrive, pscheck.... we could o/c cpu an gpu for exemple with overdrive....

with msi AB i can t oc the gpu of the apu, just i don t know if ther is a software which can do this

 

an idea???

 

You should be able to OC the GPU bit.. Try Saphire Trixx...

 

hi TomJGX,

i try but no result again.... not possible ti change value....

 

Hey Hey Hey... If Overdrive doesn't work with this, my theory is right.. AMD has locked the A4 CPU's down as they're budget.. The A8/A10 aren't and the Lenovo being lenovo locks down everything in BIOS so yes that's where your problem is if everything doesn't work

 

Temash/Kabini (Jaguar based) CPUs cannot be overclocked at the moment as there doesn't exist software capable of accessing the low-level hardware. In my opinion the closest software that could have been able to would've been the old BrazosTweaker which was under a new developer looking to add Temash/Kabini support but the project seems dead now as it doesn't have any backing or funds.

My Temash A6-1450 GPU can be overclocked to 497 MHz (up from 400 MHz) using MSI Afterburner 4.0. Your Kabini A4-5000 GPU should be able to as well. Did you make sure to "Enable low-level hardware access interface?"

During your testing, under "AMD compatibilty properties" check the following boxes:
-Extend official overclocking limits
-Disable ULPS

For example, enable low-level hardware access in settings:



While my A6-1450 CPU cannot be overclocked, it can be locked to operate at 1.4 GHz (1.38 GHz to be exact). The A6-1450 is a little unique in that it was the only Jaguar-based CPU with a Turbo feature. Without locking it to 1.4 GHz, the CPU clock will fluctuate from 1.0-1.4 GHz normally but will not remain at its max clock for more than a second. Using my Acer Aspire V5-122P, I can locked the CPU clock to 1.4 GHz simply by putting the computer to sleep and then waking it right after. This then causes the CPU to operate at 1.4 GHz all day (unless you restart, hibernate or shut down).

 

@ Tom
Yes the cpu is locked but we can try to oc with the PLL to change the fsb....
but i would like to oc the gpu too...
do you knows if lenovo have unlocked bios?

@david
I will try this tonight and i post the result.
bt when i try i can change the frequencies but in fact no change, msi put the stock frenquency...

 

hi david

i try again msi AF with the box to check
I can change the values.....

.... but when i apply, the frequencies not change... i do't know why ....

 

BIOS is the problem.. lenovo always locks everything down in it...

 

you think bios block frequencies of the gpu ???

it s strange, block the frequency of the cpu ok but gpu

another pb, i see that memory run at 667Mhz but it s a corsair 800mhz.

A4-5000 can run with this memory, when i do a diagnostic memory it s check à 800Mhz but Cpuz show 667Mhz

 

Can you take a screenshot or picture and show me? I can OC my a6-1450 GPU from 400 MHz to 497 MHz using MSI AB. I'll post a picture later for you.


Here are the GPU and RAM specifications.

Can you post your RAM brand and model? Something doesn't seem right, please try again with HWiNFO64. http://www.hwinfo.com/download.php

Well I meant vBIOS... No idea since these APU's are not my stuff and something completely Alien to me..

 

david how do you do to change gpu frequency?
for me it s impossible.

using msi AB if i change value and check applicate, the value not change...
what screeshot do you want, cpuz, GPUZ MSI AB???

 

maybe there is a unlock bios, no???

Sorry for the time for my response, but for chrismas, i don t have to much time

 

At this point, I would honestly give up...

 

In short, your AMD A4 is what it is. And your BIOS ls locked out. Accept it for what it is.

 

Couldn't say it better.. +100...
