How much is the P4 2 8G now?

About 900 yuan, P4 is used in office, field, multi-tasking operation has certain advantages (limited) It is recommended to use AMD3000+ 939 interface E6 version is more cost-effective, giving you more entertainment to enjoy,

It's not worth it to use the p4 of the core now.

It's not worth it to use the PD series now.

Used CPUs for P4 are hard to find, and finding them is not much different from a new one, so it is recommended that you buy a new one. ** is around 850.

I regret buying it'' (AMD P4) There are too many misunderstandings between them.

AMD: Okay.

You're already an antique in an antique.,There's no way to upgrade it.,2007 was the time when the big replacement CPUs began to enter the 2-core and 4-core,Single-core was eliminated。 Last year, it also began to be replaced, and 6 and 8 cores were popularized. Just buy a new one.

The CPU that has been eliminated, the P4 is a little bit better,

The front-side bus of the CPU is related to the external frequency, generally four times the external frequency, the front-side bus of the motherboard can be described as the width of the data road, the wider the data capacity, and the memory is the other end of this channel (this end is the CPU), the motherboard first tunes the data into the memory, and then from the memory to the CPU processing, so the front-end bus of the three can play the maximum efficiency, your situation can appropriately exceed the external frequency of the CPU, 533 divided by 4 is 133, You can go over the clock speed to 133!

533 is about 20% faster than 400! The problem that you can solve by overclocking, there is no need to spend money in vain, it is better to save the new one later, now the front-side bus between the CPU and the motherboard has reached 1333!

The worst of Intel's first-generation dual-core CPU is PD805! The PD805 is clocked at 1x2M for L2, and the worst dual-core ratio is much stronger! Single-core can't be compared to dual-core!!

Single-core vs. dual-core can't be compared like this! They don't work at the core and work in different ways. The dual-core processor can stream multiple audio,** or game data to different types of users at the same time! The speed is greatly improved compared to a single core!

P4's is right, mine is P4's super stupid thread-destroying CPU, and B's doesn't support HT technology.

It is recommended to test it with software.

I estimate it to be 1g

Dismantled the 256MB mounted on the machine.

It doesn't matter if you add memory and CPU size, depending on whether the motherboard supports how much memory, then you can buy a DDR400 512M 80 Add it to 256M to 40, It depends on how you match, play games At least use more than 1G of memory, Office, almost 512M is enough.

Remember to buy memory with the same frequency , memory with different frequencies may conflict and be undetectable.

The motherboard supports up to 2G of RAM and is also 1st generation which is DDR 400

Add a copy of Kingston 1G DRR 400 220 Yuan If you have more, you don't need it

The best solution is to add a second-hand 256 (30 blocks) of memory each. Reason: Now no one has upgraded the memory of 256, making it a chicken rib in the hands of second-hand merchants, and merchants are willing to change hands at a low price; The capacity is not large, but it is also doubled the memory, and the improvement effect is still obvious; There should be a computer store around the school, and if you say it's a teacher, he generally doesn't dare to lie to you.

Mining to the maximum needs to increase the memory to 1G, but considering the problem of school use and funding, you can consider buying second-hand 256M memory, in this case, you can already meet the needs of the school without running any big software.

I have an idea, to disassemble all the memory, and then on 1G, only buy Kingston's, fake is fine, other "brands" are even worse, because the market generation of strips out of ten nine is fake.

It refers to the main frequency of the CPU, which means that your CPU performance is still alive.

Your motherboard may not be able to support a single 1G memory. Let's test it with everest software first,If you support a single 1G, buy a 1G,If you don't support a single 1G, you can only buy two 512M。

Kingston gets 150-180 for 1g

Just follow this.

However, I'm worried that your motherboard doesn't support 1G.

You add a 512 no problem 512 DDR frequency of 400.

The memory model is DDR4001G, which is OK.

P4 520, this is a desktop single-core CPU, which is older.

D525 , this is a dual-core CPU for notebooks.

It must be dual-core good, the performance is much better, not in the same era.
