Memory upgrade on HP Probook from 4gb to 8gb

[rm1977]

I have HP Probook 6450b Core i5 processor laptop that doesn't like 8gb memory upgrade. I bought the right kind with right speed and BIOS shows the right memory installed but it gets stuck at "starting windows" screen. I upgraded the BIOS to latest version and hard drive is new....if i put the older 4gb (2x2) chips back in there, it boots just fine. Memory was new and never even used.

I think some setting has to be changed but i looked everywhere and even changed the quickboot to normal boot but that didnt help either. Safe mode doesnt work either.

Any other ideas? Can i try some other setting or change something that'll make it work. Thanks

Memory model i am using

Model: CMSO8GX3M2A1333C9
Type: 204-Pin DDR3 SO-DIMM
Capacity: 8 GB (2x4GB)
Speed: DDR3 1333 MHz (PC3 10600)

So one more thing i noticed is that it doesn't take 1 - 4gb chip at any given time. It doesnt even show the BIOS screen unless i install both 4gb chips and then it shows 8gb in BIOS but gets stuck at "starting windows"

I am having the exact same issue right now with the 4gb to the same 8gb(Corsair) kit you have. With 2x4gb installed, I get a Windows Error Recovery, but I reinstalled the 2x2gb that were original and no problems at all. Another odd thing that I experienced was that I had bought the same 2x4gb kit three weeks ago, installed it, and it ran fine for two weeks. Then, I was running a calculation and my notebook froze. Eventually, restarted it with the former 2x4gb and everything was fine. I thought it was related to the RAM, so I got a replacement and now my computer won't load Windows with the 2X4gb kit installed, but it runs fine with the 2x2gb. !?

have you check the memory voltage? maybe it's related? :-/

Yes, I tried one RAM card at a time as well and it won't even get to the splash screen. Also, I have an HP G62-400 CTO and the BIOS won't even let me get to the RAM voltages as far as I know. My BIOS does not even show an advanced tab. One other possibility, I have a dying battery, it doesn't hold a charge nearly as long as it used to and fails the system diagnostic battery test. Could this affect the installation of new hardware as well? I know that I am on AC power when I am doing all of this, but could the new hardware plus the battery failure cause the system diagnostic to fail and hang so that windows can't load?

Hi

I have the same issue here. Did someone find a solution for this?

Hi again

It got the memory modules replaced and it's working now. I'm using these ones:

For those that are still wanting to do this, I have discovered that this HP is very fussy regrading RAM upgrades. I tried a couple of RAM manufacturers without success. I contacted HP and they said CT51264BF160B, 4GB 1600MHZ DDR3 SO-DIMM (LAPTOP) DUAL RANK. I did a quick search on Google, and came across the Crucial website and found these:

If you are in South Africa, I bought them here:

I got them yesterday, popped them in last night and Windows booted up perfectly. It was true plug n play experience.

Hello, you require the DDR2 PC2-6400 800MHz 200-pin SODIMM
