ProBook 4540s - Maximum Supported Memory ?

[thilina1024]

I will buy a ProBook 4540s (Intel i5) very soon.

At a lot of places on the Internet, it had been mentioned that it supports upto 8GB DDR3 RAM. But, on a details page at HP site, it had been mentioned as "16GB". So, I'm a bit confused here, though I guess that it might be 8GB. I want to know about this for sure.

Thanks 🙂

Thank you for the quick reply. Glad to know that it supports up to 16GB. 🙂

Yes, it does supports 16 Gigs, however the performance degrades as the 16 Gigs are enabled. I downloaded and upgraded the latest BIOS sp60202 and still having performance issues. Is there a new BIOS update or something we can do.

Thanks

@davegu1: Thanks for the reply. 🙂

I'm wondering, if it supports upto 16GB, how there could be a decrease in performance after upgrading RAM. Explanation from anyone would be great.

Any new experience with 16gb? bios/other solutions?

cheers

@thilina1024.

Yes, there is a degraded performance after you put the two 8 Gig sims. Upgraded the latest microcode for the laptop, memory, drive, etc. And the 16 Gig is still not responding as fast as when I have 8 Gig.

same issue about Probook 4441s with i7. If the ram was upgrade to more than 8G, the CPU and GPU seem to be frozen and performance slow doan.

really hope HP give us the solution to fix the issue..

if it's in Bios we can have hope, but maybe it is something with HP policy, 4540s with 16GB ram would have been PERFECT machine... at least for me.
