Questions about the Athlon 1800 overclocking

Your motherboard is an NF2U400 chipset.

There is an independent crystal oscillator that supports AGP PCI frequency locking (regardless of the external frequency, the AGP graphics card is fixed at 66, and the PCI hard disk is fixed at 33).

Therefore, no matter how much overclocking is overclocked, it has no effect on the graphics card, hard drive, and sound card.

However, the motherboard supports memory asynchronous, which reduces performance significantly.

It is best to synchronize the memory, your external frequency is 210, and the memory is DDR 420.

It is estimated that your memory is 100 purple and red.

The highest can exceed DDR 430 (corresponding to the external frequency 215).

Therefore, your external frequency of 210 should not be too high.

A few other suggestions:

1. Whether the overclocking is stable or not, you can run 3DMark01 and other software for a few hours to test.

2. After overclocking, the CPU and the northbridge can add some voltage, and the heat will increase at the same time. Especially in summer, pay attention to the ventilation and heat dissipation of the case.

3. In CMOS, set the memory parameter to: 1T (command rate). It can also improve the performance of System 5 or so.

I checked it for you just now.,Yours is Lenovo's motherboard,KT400A,I didn't find that there is no overclocking option in the BIOS,If there is,It's easy,You directly put the 133 external frequency up to 166,So that 1800 becomes 2400,It's very cool,It's also very stable,What other compatibility problems!

If there is no one in the BIOS, then you have to read the motherboard manual, open the case, find the jumper that controls the external frequency of the CPU, and reset it, and you're done! It's better that way! I don't know what memory yours has, the memory of 266 runs to 333m is generally fine, if it is 333 type 400, of course it is even more fine!!

It will not affect anything else, that is, you should pay attention to your heat dissipation, be careful to burn the CPU and motherboard, and it is recommended to change to a high-power fan.

Overclocking depends on a lot of factors.

You're doing pretty well right now.

However, when overclocking, you should pay attention to lock the AGP and PCI frequencies, otherwise, the sound card and graphics card are prone to failure under overclocking.

If you are using DDR400, you should not need to adjust the memory frequency to ensure that the frequency of the memory does not exceed the rated DDR400.

Also, pay attention to heat dissipation.

I feel like you can keep the octave down, and then increase the outclock, and if you're lucky, it's still possible.

Overclocking is not a big problem, as long as the heat dissipation is good

PF can use the core fan-mounted XP. 2400 can generally be reached, and now it is more than p4

Much better.

The memory of the same brand is generally compatible,Super should be able to 2000-2200,Look at the performance of your CPU,To change a better fan,My 1800+ can be super to 2500+,But it's still not super good.,Hurt CPU.。

Generally speaking, you can continue to overclock by adding voltage, which can be adjusted in a similar option such as Processor Voltage Control or CPU Voltage Control or Settings.

Another situation is that other devices are abnormal because they cannot keep up with the changes in bus frequency, such as memory, graphics cards, PCI devices, etc. Memory can be properly voltaged, but its adaptability depends on its own qualities. It is best to lock the bus frequency of the graphics card and PCI equipment, otherwise it is easy to have problems.

Another possibility is the quality of the motherboard itself, if that's the case, friends, resign yourself to your fate.

You'd better not tune the weather day now that it's going to burn out the CPU.

You just need to set the memory MHz to the maximum.

AMD1800+ is very easy to burn, and it is also possible to overshoot. But you have to be mentally prepared. If you can't use it anymore, then be super!

It's best to change the CPU fan before overclocking, and if you can't afford to buy it, then clean the CPU fan with some oil.

My 805 is over 20%, and it's okay after using it for 5 months! Hehe, if you are reluctant to buy a good CPU fan, don't cover the case cover after overclocking. It's best to find an electric fan to blow it, and you won't need it in the fall. Huh

146MHz is not a standard frequency is very unsafe, 166 is recommended for the external frequency.

The frequency of the + multiplier cannot be set to run under normal circumstances, but the result of my overclocking is stable.

The external frequency of the same can not exceed 150 under normal circumstances, and the phenomenon of this orange liter is that the crash machine cannot even be started normally. My situation is to shut down and turn it on again after a while, or restart it a few more times. If it really doesn't work, just put it to the end.

Yuan Da Lao I super external frequency to 145,The highest is 148,It will be unstable in the high system,No way,The heat dissipation is not good,I don't know how much the CPU voltage is appropriate,The level is limited。

BIOS battery discharge! Right away.

Pick off the battery on the motherboard and put it back on.

It's all possible, if you can use the liquid light CPU, then there is generally not much problem with overclocking, and there must be a sufficiently high-power power supply under normal conditions. Then in the end, the motherboard is generally suspected. A good motherboard is crucial for overclocking.

You can add some voltage appropriately.

In fact, the best way to overclock is to reduce the frequency multiplier and increase the external frequency.

For example, if you are using 166x11 now, you can change it to 200x8, which is definitely faster than the previous one!

Can the AMD1800+ still be surpassed? Don't burn it, be careful.

Hello, this CPU itself is hot enough, you still have to overclock, don't you want to burn the CPU, if your CPU radiator is fierce enough, try a small super, super to try it, if you use the original fan, don't overshoot, the original fan is difficult to suppress, now it's summer.

If the memory is DDR333, please asynchronously, 1 to 1 is fine, and it may also be a quality problem of the CPU.

It is necessary to see if there is a problem with the COMS power supply, which causes the BIOS to not be saved.

Or is it more likely that the memory will be asynchronous.

Then you tune it to by....That, or directly syncing 1 to 1, the transition downscaling will also lead to failure.
