Asus K43SJ processor upgrade question

[jingalalahoe]

Hello folks!

I have an Asus A43SJ with a Pentium B940 processor in it. I want to upgrade the processor and need suggestions for compatibility

As per official Asus, Core i7-2630QM should work . Link to specs - https://www.asus.com/my/Laptops/A43SJ/specifications/

I'm wondering if a i7-2670QM will work, I can get it slightly cheaper than the 2630QM plus it will be slightly faster.

Link to BIOS - https://dlcdnets.asus.com/pub/ASUS/nb/K4...JAS317.zip

I can open the BIOS thru AMIBCP 4.55 and MMtool 5.0.0.7 and here's some screenshots if it can help. I really cannot figure how to proceed from here so asking your help!





Thanks in Advance!

I think that quad cores CPU will overheat this laptop.
To check it you need to stress current GPU and CPU simultaneously: run Furmark & LinX (with idle process priority).
Make screenshot of HWMonitor when GPU & CPU temperatures will stop rising.

Leaving aside the heating, will it work on the laptop? I can probably do some mods to take care of the extra heat.

I could probably get an i5 2410M which is also on the supported processors list and has same TDP as the 940 but if possible I want to go all out on the upgrade 

on a different note, will i5 2540M also work? I'm having second thoughts on the i7 due to thermal constraints.

Some motherboards can't boot with quad cores CPU because of hardware limits of power subsystem. On motherboard, not PSU.
i5-2xx0M и i7-26x0M are recommended for your laptop.

Thank you for your inputs, ordered an i5-2540M. I'll update the thread when I get it!

SO I got my processor and it works fine!



Before installing it, I updated the microcodes in the bios to the latest and unlocked as many options as possible in the BIOS.

Processor idles at 37-38* , wow! Earlier witht he 940 and the same thermal paste it never went below 50* idle. Load temps are the same, this is after 15 minutes of prime95 and its turboing to 2.8GHz on all cores? I'm running a 65w brick instead of the standard 90W. Hopefully it runs faster witht he 90W hehe.



Windows is lot more responsive even with prime95 running! Spent 35$ on the cpu and it was worth the upgrade. Now I keep thinking if I should have got the i7 haha

Hi Jingalalahoe,

I have the same model as yours (Asus K43SJ), currently with a i3-2310M processor.  I'm planning to upgrade to i7-2670QM or i7-2760QM. 

Which of the two would you recommend?

[DeathBringer]

None of these two. Reread this topic attentively.
