HP g3421cx memory, why HP g4 2303tx notebook memory is 4G, but only 932MB is available

HP G3421CX The whole machine is configured with AMD Athlon64 X2 4200+ dual-core Athlon, the main frequency is 1G DDR2 800 memory, the hard disk is 160G, 7200 rpm serial port, the optical drive is 16X*** with PCI-E 16X expansion slot, it is recommended that you add another 1GB memory, build a dual-channel 2GB Add a graphics card, 9500GT, it's best to replace the power supply After all, the maximum power of the randomly matched power supply is only 215W, and then the CPU motherboard becomes a bottleneck It doesn't make much sense.

Hello, I have been doing computers for many years, and I unanimously recommend a single memory, and I do not recommend multiple sharing. Especially the old machines.

Please sell the old one and buy another big one.

Because, first, if you buy a memory and add it, the memory will become two, 512 is 533 1G is 667, and the main frequency will automatically support 533Reduce the speed. Even if it is the same frequency, the manufacturers are not the same (for example, blue screen, restart, prompt file corruption, boot multiple times to enter the system, etc.).

Second, the single memory running system (excluding antivirus software) is about 150M. The twin strips run to about 220m. In fact, it is not difficult to see that when you open the task manager (press Ctrl+ATL+DEL) after you boot the system, you will see that the single memory process (is 4, and the double is 6 or more.

Why?? Apparently both memories run independently. In order to exchange data, 667 had to be reduced to 533

But the swapping of two memories takes time, and the speed is not much faster than a single one, so I don't recommend it.

Please refer to it.

I don't know if the landlord has solved this problem.,I just bought a 2303.,Memory is only 932 available.,The running program is very stuck.,If you've solved it, please tell me the method.,Thank you!

Pit, ah......I'm also this problem.,Just bought it not long ago.,That's it for the 64-bit system to be replaced by a 32-bit system.,Did the landlord solve it? Ask for guidance, thank you.

Remind you that there is a certain risk in flashing the BIOS first, and if the hardware problem caused by the failure to flash the BIOS needs to be borne by the user, if there is important data in the computer, it is recommended that you back up the data first. However, according to the feedback from users, the security of the BIOS refreshed under Windows is still relatively high, please consider carefully before doing this!

Below I will tell you about the precautions for flashing the BIOS:

1) Connect the external power adapter and battery to keep the computer in a stable state of power supply (2) Do not run other applications in the background during the refresh, such as anti-virus software, etc. (3) Do not interrupt abnormally during the refresh.

Most notebooks should double the amount of memory when they buy it.

You can purchase the same model as the original.

1. HP G42-384TX, the maximum memory supports 8G2, the memory is DDR3 series, since you are now Samsung DDR3 1333, it is recommended that you buy the same, because Samsung's is not difficult to buy. The compatibility of the same frequency and brand is better.

3. You can buy other brands, and DDR3 1066 1333 1600 is OK, but there may be poor compatibility (relatively rare).

There are no requirements, if there are no special requirements for compatibility, almost, as long as it is DDR3.

The maximum memory supported by your machine should be 8G, which can be added.

If your current system is Win7, the 2G memory is a bit small, but if you want to add memory, the system must be 64 bits, because the 32-bit system supports a maximum memory of more than 3G.

Probably not.

The configuration of this machine is not low.

The already 2 gigabytes of RAM are no longer the main bottleneck.

It's just that the bus and frequency are slightly lower.

I think your speed has something to do with the system.

FYI. ====If you have 2G of memory, then it doesn't make sense to add another one, this is based on experiments.

In addition, it should be noted that try to avoid obtaining memory through online shopping, so as not to be unable to identify the impact of hardware compatibility, and memory dealers will not return it, which will cause you inconvenience.

If a 32-bit operating system is installed with 4GB of memory, it will not fully utilize the full capacity of memory due to the limitations of the memory mapping access of the system itself, which is normal, and it is recommended to install a 64-bit system in order to fully identify the memory capacity and use it.

We hope you find the above reply helpful.

Add 2GB of RAM, and if you use a 32-bit system, you should only be able to recognize it.

You can buy a good upgrade that matches your phone model, and it can be expanded to a maximum of 8G

The memory is very easy to upgrade, just buy the corresponding model and plug it in.

Of course, the bigger the memory, the better. Now 4G is standard.

Since your laptop runs smoothly when surfing the Internet, it means that the hardware aspect of the notebook is normal, if you encounter problems with the hardware aspect, then it may not be smooth when performing any operation, so it is recommended that you open other software tests:

a.If the problem persists, it is not ruled out that it is related to the software, you can try to disable the boot startup item, start --- running--- enter msconfig to uncheck all the unnecessary enablement items (such as msn qq Thunderbolt eMule virtual optical drive, etc.); If the problem persists, then you can back up your data and quietly install the original operating system.

b.If other software can run normally, then it is recommended that you check the operation requirements of the software that is not smooth, if the software and hardware of the machine are in line with the software operation requirements, you can upgrade the latest version of the software test, or contact the special support department of the software for specific consultation.
