Hp Probook 450 G6 Memory

[Barton Ostby]

Soundsodd why it would throw a fit. Would try again and switch the sticks around perhaps? The Probook 450 supports that configuration as it supports up to a 8GB stick in each slot. It does show it should be happy running dual channel with 1x8GB+1x4GB configuration. (Page 2) As noted, but not that it should make or break an upgrade, was the BIOS up-to-date before upgrade time?

From the Maintenance and Service Guide:

Update BIOS before adding memory modules

Before adding new memory, make sure you update the computer to the latest BIOS.

CAUTION: Failure to update the computer to the latest BIOS prior to installing new memory may result in various system problems.

NOTE: Due to the non-industry standard nature of some third-party memory modules, we recommend HP branded memory to ensure compatibility. If you mix memory speeds, the system will perform at the lower memory speed. With Windows Starter 32-bit operating systems, the amount of usable memory is dependent upon your configuration, so that above 3 GB all memory may not be available due to system resource requirements.

The thing is that i need this memory quickly and I can't find DDR3L, now i'm using corsair Vengeance and I need the wake on lan function but that message which let me use the computer if I press enter, doesn't have any countdown with default option and no BIOS settings so I want to modify that and either add a timeout that would boot the laptop or simply disable that message because it's working, i'm using it now.

You don't seem to understand how it works with memory primary and secondary memory timing and bus voltage settings. the notebook BIOS ROM file has settings in its coding for memory modules that meet the compatibility requirements. If you install memory that has not been tested for compatibility, then it just won't work or even it seems to work, it will be unstable.

A notebook BIOS is absolutely unlike a BIOS that is present in an enthusiast level gaming motherboard. There are no adjustable timings and voltages for the memory timings or bus voltages in the BIOS of a standard notebook's BIOS. It is actually protecting the owners from themselves. You are not "doing 1.5 to 1.35". You can't change the bus voltage setting to anything other that what is set in the BIOS. If the memory module you install does not accept the voltage set by the BIOS coding then you are simply out of luck.

The following memory modules manufactured by Crucial are guaranteed compatible. Another brand to try would be Kingstonm memory. Any non guaranteed compatible memory module you install will ba a waste of your time and risk of your data.

The graphics memory on laptops feeds off of a certain percentage of the system memory. If you want more graphics memory, add more RAM. If your laptop can't take more ram, then you will also be unable to upgrade the graphics ram without a new system.

8 gigs is the max or 2 x 4 gig modules. 8 gigs is very expensive and you may want to consider only installing 4 gigs...you would hardly notice any difference except in the wallet. 4 gigs will be noticeably better than 2, however. Here is a link to a memory seller with pictures and a description of the type of memory you need. It is DDR2 800 mhz also known as PC2-6400 SO-DIMM or laptop memory. You can buy it just about anywhere laptops are sold but 4 gig sticks are a bit hard to find except online. 2 x 2 gig kits are very commonly available. Shop around for the best buy but stick with a name brand. This is Kingston which is always good.

I have one other questions please: Does the notebook take DDR2 or DDR3 memory modules. Accoring to my understanding of the official HP ProBook 4510s Notebook PC Maintenance and Service Guide, this model takes either DDR2 or DDR3. My understanding of the guide is that some units took one type of ram while others took the other.

Thank you for your reply. Is there a way I can find out the memory in the unit without having to open the unit up. The main reason is that the fold who designed this notebook made access to the memory a really hassle.

The Service Manual has a chart on page 4 of Chapter one saying which models have DDR-3 and which have DDR-2 but there is a note that says the model number cannot tell you which it has. I guess they switched to DDR-3 somewhere in the production run.

A system diagnostic program like CPU-Z will tell you they type and speed of memory installed in the system without cracking the case. You are right there are a lot of gyrations needed to install memory:

I've just bought a new HP ProBook 470 G1 with Windows 7 installed and I wanted to upgrade the RAM, so I got an extra 4GB RAM chip (Corsair Vengeance). I think I've managed to fit it absolutely fine (it looks exactly the same in the mountings as the other 4GB chip that's in beneath it and I was careful not to touch the components), but it's saying that "The system detected that an unsupported DDR3 memory type is installed" and then quotes the error code in the subject line above. What's even weirder though is that I hit continue anyway and go into my computer's property's and it's saying it's now got 8GB of RAM, suggesting that it's working fine but it keeps running the error code every time I boot up. On top of that both the Graphics card and the original RAM are quoted on the specs as being DDR3. Two questions:

I am not a PC repair tech by trade or training, but you may be placing too high a demand on the system board which is designed to run memory at a certain voltage and you are asking it to deliver more power than it was designed for.

I've bought a HP Probook 450 recently. And I upgraded the memory from 4GB to 8GB. I added a 4GB DDR3 Samsung 1600MHz PC12800. But when I start the laptop, it shows error "DDR3 memory type not supported. And it said I should remove the added RAM.

It uses DDR3L (low voltage 1.35 volts) and you may have tried to install regular 1.5 volt DDR3. If this is not right then please provide us will as much information as you can (from the label) on the memory you have added.

I read EVERYWHERE that the memory should be 2 identical SO-DIMM modules with the same size and the same voltage, speed and timing but the memory that was originally installed is 1x 1600 mHz and 1 x 1333 mHz ... with different timing and from different manufacturers.

I tried every possible configuration but when running Memtest the system crashes every time when it reaches above 4096 M ... so 4GB ... which leads me to believe that is the maximum amount of memory which is supported although the manual says it should be 8GB.

You need to make sure you do not exceed 1333 MHz (which you have), and it needs to be PC-10600, not 10666, etc., and the memory modules have to have 8 of the little black memory chips on each side of the circuit board, not 4.

I have helped no less than a dozen forum members around the world who have probably put more money into memory that doesn't work (though the specs say it should) and their Series 5 chipset notebooks will not accept the memory.

but still I really find it odd that it matters if the memory modules have 4 or 8 chips on each side ... since the ones that are originally in it have only 4 ...which ... according to you should not work !

Hello. I need some help with a memory question. I just purchased an HP ProBook 470 G3 with Windows 7 Pro (64-bit). I'm installing an SSD and want to upgrade the memory as well-- it only came with ONE 8GB stick.

The first question is more like a request for confirmation-- because the memory that's installed is NOT what is listed in any of the specs or the Service & Maintenance Guide. Those all list it as: PC3L-12800, 1600 MHz, DDR3L. But the memory stick itself is labeled DDR4. I also verified it with CUPZ and it's shown as DDR4 as well (DDR4-2400). My guess is they upgraded the laptop, but not the manuals.

Question #2 (this one IS actually a question): CPUZ lists the stick as SINGLE channel. So can I purchase anohter 8GB stick and install it, or would it require replacing BOTH to upgrade to 16GB (2 x 8GB)?

Then if I look for a SINGLE stick, will it be SINGLE channel? I looked for some on Newegg, but they don't seem to list whether it's single or dual channel. If it sold as a single stick, can I assume it's SINGLE channel? They also have what seems to be TWO different 8GB DDR4-2400 Crucial stick, but with a wide gap in their pricing ($63.99 vs $86.99). I've purchased and installed a lot of memory in my time, but I'm not familiar yet with DDR4 to know what to choose.

As long as you get a second 8 gig stick of DDR4-2400 RAM and install it you will have 16 gigs and it will be dual channel. Any single stick of memory will be single channel because it is in one channel. A second stick of the same memory (or with all the same characteristics-speed density latency)-will allow dual channel memory operation as long as the motherboard supports it which your does. I have a Zbook 15 G3 which is very similar. Came with a single 8 gig of DDR4-2133. I went to Frys and bought what they had on hand for an 8 gig DDR4-2133 chip, installed it and mine is running in dual channel mode.
