Question about memory

[Ugljesa73]

Good day i have a hp compaq cq5340sc desktop and i have 4GB RAM at the moment. I would like to upgrade the computer a bit. Can I put two DDR 3 of 4 GB and have 8GB of memory?I have Windows 10 64-bit.

Hi:

Not according to the motherboard specs at the link below...

https://support.hp.com/us-en/product/compaq-presario-cq5300-desktop-pc-series/4079828/model/4119329/...

The max is 2 x 2 GB.

The chipset specs indicate the same.   With DDR3 memory, only 2 x 2 GB is supported.

you might (and i say might) be able to use two 4gb DDR3 memory sticks in your G41 chipset based motherboard however to do so you need a specific configuration.......The G41 Chipset can use up to 8 Gig of memory but the modules have to made with 128M X 8 Memory IC's these modules are often refered to as low density and as far as i know very hard to find new

the paragraph below is from the corsair web site

I cannot comment about another manufacture you would need to speak with them for information on their products.
However, on our modules CMZ8GX3M2X1600C7R please look on the module and you will see the version number.
If the version is X.X they are made with 128M X 8 or 256M X 8 IC's and should work with the MB you have.
If the version number is X.XX they will be made with 512M X 8 memory IC's and would not work with the MB you have. 
And 90% of what we produce now will be version X.XX, granted some will be made with lower density IC's; there is no way to specify the version number as most resellers will not know or tell you the version you will get. In addition, even if it is a part we sell direct our Customer service will not know what version you would get of any specific part nor can they specify a specific version on an order. Hope that helps!

the reason why 4gb is listed as the max is that the system was never tested/validated by compaq/intel for larger modules so they only list tested configurations

i do know that dell made a optiplex 380 model with the g41 chipset that could use 8 gb ram so it's possible your compaq board will also, but as i stated it's not a sure thing only thing, all you can do is try and see what the results are 

this memory kit may work for you

I bought a new RAM Kingoston Hypers HK318C10FB / 4 and I plugged my computer into a computer and when I started the computer, I heard a beep and it will not be but. What should I do?

[DGroves]

I don't know,....how about you take the time to tell us which model computer you have so someone can provide help

Hi, @DGroves

This person is the same individual that wanted to know if a 4 GB memory module would work in a CQ5340SC, to which I replied 'no, it wouldn't.'

It appears that @Ugljesa73 installed a 4 GB memory module in the PC and it didn't work (as I expected).

So, it is one of two things...the memory is not the right spec, or no 4 GB memory module of any kind will work in that model, in reference to the HP and Intel specs regarding the chipset.

Looking at the memory specs for the module installed, there was no way that would work.  It will not downclock to 1066 MHz.

You cannot exceed PC3-10600 in that chipset.

So, there still may be a glimmer of hope if you install a 4 GB memory module with the right specs (DDR3-10600).

you don't see issues with the type of memory chips used nowadays but it used to be more of a issue around circa 2010

you could have two 4meg memory modules but the number of chips used on the modules would differ, this was because some modules used sixteen, 256x8 chips and the other used eight 512x8 chips  on the dimm

early intel (and other chipset makers) had memory controllers that could only work with the 4meg 256x8 low density dim modules

no memory maker is currently making low density dimms, you will have to search on places like ebay for a 16 chip 4meg dimm

[Paul_Tikkanen]

I agree.

However that 4 GB module installed had zero chance of working because it could not run at 1066 MHz.

1333 MHz was the slowest clock speed it could run at, so the Series 4 chipset couldn't handle it.

@Ugljesa73  If you can get one of these, it will work if the chipset can support 4 GB per slot.

I used this in my HP 8000 Elite CMT with the Intel Q45 chipset and it worked just fine.
