How big is the memory of my computer, which brand and how much is the price?

The motherboard of the 945 generally supports 4G DDR2 533 memory, but now it is DDR2 800 memory.

Your motherboard supports 100% 2G DDR2 800 memory.

It is recommended to choose Kingston DDR2 800 **150 yuan 1G **80 yuan pay attention to anti-counterfeiting!

Now 533MHz is not much. Your computer has reached the point where it can be updated.,Don't add memory.,Prepare to buy a new one next year.,If you add it.,The effect may not be good.,Mine is added.,Just add a 1G one.。 Preferably a brand, a frequency.

It doesn't matter how much memory size 1g 2g is OK memory is now 1g 70 2g 150

The main problem is compatibility (Kingston is recommended) After you buy it, test the compatibility first, and test it with memtest.

DDR2 533MHz memory I don't know if there are any other ones on the market.

However, your motherboard also supports DDR2 667MHz

If you have the money, it is recommended to change the machine.

2G is almost, for frequency, buy an 800 one.

No matter how much it is, the graphics card is an integrated display, which will not improve much for the game.

The CPU is also not strong.

I don't know what the price is in your location, what do you think of this configuration? In Shenzhen, the total is probably, now it is beginning to be peaceful, the computer must be constantly upgraded, in order to catch up with the situation, 2G memory modules are also peaceful, each approximately, the larger the amount of memory, the faster the speed of the computer, it is recommended that you have 4G memory.

The brands of memory modules are different, regardless of the size of the capacity, they cannot be mixed together, and the performance indicators are different and incompatible.

Performance metrics for memory.

There are four performance indicators to evaluate memory modules:

1) Storage capacity: that is, the amount of binary information that can be contained in a memory module, such as the storage capacity of the commonly used 168-line memory module is generally 32 megabytes, 64 megabytes and 128 megabytes. DDRII3 is generally 1GB to 2GB.

2) Access speed (memory cycle): that is, the minimum time required between two independent access operations, also known as memory cycle, the access cycle of semiconductor memory is generally 60 nanoseconds to 100 nanoseconds.

3) Reliability of memory: The reliability of memory is measured by the mean time between failures, which can be understood as the average time interval between failures.

4) Performance ratio: Performance mainly includes memory capacity, storage cycle and reliability, performance ratio is a comprehensive index, for different memory has different requirements.

512M memory, according to the configuration, is built to take 512 for a 1G memory of the same frequency.

Uh, the landlord's machine is old enough.

It's nothing, your machine CPU is Celeron 512 megabytes of memory, and you don't need to change it, just this one, because it's too old, unless you buy a new one, otherwise there's no need to change it.

This motherboard only supports up to 4GB of 1333 RAM for a total of 24GB and can be overclocked. Because this motherboard supports three channels, it is recommended to buy two 4GB memory of the same brand and frequency as the original memory to form three channels, the performance improvement is more obvious, and the capacity of 12GB is enough.

Add a Kingston DDR3 1333 4G on it.

I think adding a 4g1333 one is enough.

Dear ASUS users, Hello!

1. K45VS supports DDR3 1600 MHz SDRAM memory, with 2 x SO-DIMM memory slots, and supports up to 2 x 4G memory.

2g ddr3 1600：hynix/hmt325s6cfr8c-pb，samsung/m471b5773dh0-ck0，asint/ssz302g08-ggnhc。

4g ddr3 1600：hynix/hmt351s6cfr8c-pb，samsung/m471b5273dh0-ck0。

Due to the compatibility of electronic products, it is recommended that you bring a laptop to install and test the compatibility when purchasing memory.

Hope you find the above information helpful! Thank you! If you still have questions, you are welcome to continue to ask.

Just use Master Lu to test it, if you add a memory module, remember to use the same frequency brand, it can be the same, this can be relaxed.
