AMD7750 overclocking issues Please help

The memory bottleneck is reached, and the doubling frequency is pulled to 15, although it does not have an impact on the memory, but in fact, the CPU speed is faster, the HT bus frequency will inevitably increase, and the number of times the memory is read per unit time is more, which puts a lot of pressure on the memory.

If you want to have a super CPU system, the memory must be asynchronous, and the voltage and heat dissipation are also very important.

Look at your northbridge temperature, the northbridge temperature is too high and it will be unstable, in addition, you can try to pressurize the northbridge, the memory timing drops slightly, and see if the memory can also add some voltage. In addition, the voltage you add when the CPU is pressurized, the same as if you don't add it, continue to pressurize. I suspect it's still cpu instability.

If your radiator is strong enough, pressurize it to retest, and if it passes, gradually lower the pressure.

There's no way around inconsistent overclocking.

When you over-double, the memory should not be affected, but the CPU after K8 is integrated with the memory controller, probably because of this problem.

You can also consider adding some voltage to the CPU and memory at the same time, slightly increase the memory timing, and use 1 memory first.

If there are still problems, then it is better not to overdo it.

The system determines the ability to overclock, how big is the ability of a U is only your own continuous exploration, instability means that the limit has passed, + pressure is not good, don't go up again.

Overclocking can make your computer run faster and more crooked, but at the same time, overclocking will also consume the CPU more than if you weren't overclocking.

The safest and most reliable way to overclock is to use the AMD overclocking tool AOD

The software can't be opened, or there is no data after opening, it can only mean that the motherboard is not supported, if it can be opened normally, click the "Clock voltage" in the "Performance Control" menu on the left, and click the mouse to appear the operation interface;

The target velocity in the upper left corner of the page is the current frequency of the CPU, which needs to be changed to break through the original frequency, and there is a clock frequency box on the lower left half of the page;

There is an HT reference frequency in the clock frequency box, which is the external frequency of the CPU, which sliding box is clicked and held by the mouse, and move slowly, generally the value of 5 increments is as small as possible, because after all, overclocking has a relatively large load on the CPU;

After increasing the value of the HT reference frequency, look at the target frequency, whether it has increased, this time is not over, click on the application in the lower right corner, the interface will be stuck for a while, if the frequency of overclocking is too high, the computer will restart directly, so the frequency of overclocking should be slowly increased, to determine that the CPU can withstand it, and slowly increase the frequency;

Finally, click OK, apply, and the entire overclocking is complete.

It is a black box that does not lock the frequency multiplier and changes the frequency to the frequency multiplier on the super-frequency multiplier steps.

Enter BIOS -- Modify the Frequency Doubling Factor -- Save and Exit and you're done with the over-multiplier.

In addition, it should be noted that some motherboards do not open the over-multiplier setting, activate it in the BIOS before you can change the frequency multiplier, pay attention to it, don't change it too high, little by little, add it once, save and exit, enter the system and test it with software, if the system is stable, then exceed it a little more until the limit, the computer will be fast and slow, indicating that this frequency is already the limit under the rated voltage. Finally, choose an appropriate frequency for overclocking! (Do not add CPU voltage and change external frequency in the novice stage).

Multiplier External Frequency 225 My M3N78 Motherboard FourG Kingston memory can be super However, there will be a blue screen occasionally when you use it, and you don't know how much you can get to your configuration! Personally, I recommend that it is more stable to use.

Your power supply may not be enough, but you can try. If you want to, you can add me q and talk to you slowly.,I'm not anonymous.,Just click on it.。 3-phase, it is estimated that it is not used n+1 power supply modulus, and the northbridge bandwidth is estimated to be insufficient, if it is n+1 power supply, then 2+1 cannot meet the power supply demand, but Onda said that it can be supported, and the power supply range must be 2+1, which is estimated to be super high.

It is estimated that it is the limit, and if you go up again, it will be unstable due to insufficient power supply.

Overclocking requires LZ to have a certain understanding of BIOS, and also some understanding of CPU, such as knowing the main frequency, external frequency, frequency doubling, HT bus frequency and the relationship between them. If LZ confirms that there are no problems, then let's get started!

This CPU can generally be overclocked without adding voltage. Therefore, we can first find the limit of the main frequency without voltage. Enter the BIOS to start the frequency doubling from the default, adjust it up (14, adjust it once, save it once, restart it once, and enter the system to run PAI.

Assuming that the CPU of LZ can be adjusted to 15, then the main frequency is 3GHz

LZ sets the multiplier to 12, the memory frequency to DDR2 667 (166MHz), and the HT bus multiplier to 7. When the external frequency (default 200MHz) is adjusted up in 10MHz increments (adjust it once to start it once, and then run PAI), when it is adjusted to 240MHz, the working frequency of the memory rises to DDR2 796 (199MHz), which is equivalent to DDR2 800. If LZ still wants to overtake the memory, then you can now adjust it up in 5MHz steps, it is recommended to 250MHz, and the memory frequency is DDR2 830 (, within the tolerance range of the memory (it is not recommended to exceed too high, which will have an impact on the life of the memory and system stability).

At this time, the main frequency is 3GHz, and the HT bus frequency is 1750MHz.

LZ is reminded to keep an eye on the frequency of the memory and HT bus, especially the memory, during overclocking. In this way, there is basically no need to add voltage for overclocking, if you must add it, the CPU will add, and the memory will add it, and there is no need to add too much (it is recommended not to add it).

Here's how to overclock AMD CPUs:

If it can't be opened, or there is no data after opening, it can only mean that the motherboard is not supported, if it can be opened normally, continue to look down.

Click on the Clock voltage in the "Performance Control" menu on the left. The target velocity in the upper left corner is the current frequency of the CPU, and the purpose is to change it so that it breaks through the original frequency, how to modify it? Read on.

In the lower left half of the face there is a box for the clock frequency. There is an HT reference frequency in the box, this is the external frequency of the CPU, what needs to be changed is it, click the mouse on which sliding box, move slowly, generally increase by 5 The increasing value is as small as possible, because after all, overclocking has a relatively large load on the CPU.

After increasing the value of the HT reference frequency, in looking at the target frequency, is it increasing, this time is not over, click on the application in the lower right corner, the interface will be stuck for a while, if the frequency of overclocking is too high, the computer will restart directly, so the frequency of overclocking should be slowly increased, to determine that the CPU can withstand it, and slowly increase the frequency. Well, after clicking Apply, click OK and you're done.

AMD that can be packed, opened, and packed

Since it didn't reach 3GHz, I asked him to return it, but I didn't negotiate.

However, this has a very strong relationship with your power supply, and the instability of your power supply greatly affects the stability of overclocking and normal use.

1-It is related to the physique of your motherboard, Onda is micro-processed by Jie, which is a channel goods;

2- Ultra is already good, after all, it is a 45nm processor;

3- There will be some minor problems if there is too much, and stability first should be considered.

There is no inevitable connection between open core and overclocking Do you not turn on nuclear energy overclocking If it is, it means that turning on the core affects the stability of your CPU If not, it means that this CPU is not suitable for overclocking Besides, you are all What frequency are you still overclocking In the past, single-core Pentium Celeron or something Because the main frequency is low, it makes sense to overtake it Now the main frequency is so high It's all quad-core Your overclocking basically has no effect It's just a little cooler.

Computer overclocking science AMD overclocking beginner tutorial is super detailed!

AMD7750 This U is good than AMD5000 5600 These are better AMD7750 I have noticed before Generally, just use the original fan to exceed it If you change a better fan, it is not good, no matter how high it is, after all, it is not 45mm process The heat is hovering between Pentium E5200 and AMD7750 when I first chose the CPU, initially it was inclined to 7750, but then I chose E5200, Until now, I still think that the E5200 is a wise choice! ^_

It is possible to open 4 cores when the CPU has shielded cores.

Your CPU doesn't have it, and you can die of this heart.

Other than that. Your CPU sets the voltage to, then sets the octave to 14, and the outer frequency goes directly to 250. The memory is set to 800. Memory latency changed to 55

515252t

Turn it on, and if it's successful, use it like that.

If the jumper is unsuccessful, the BIOS is restored.

Then press the above settings again, and the memory is set to 667.

The most common is a black screen after overclocking, which is one of the most common problems encountered in overclocking failures. When this problem occurs, you only need to press and hold the INS key when booting up, or use a jumper to clear the CMOS setting, and the CPU frequency will return to the default setting, and then you can lower some frequency settings again.

Frequent crashes after overclocking. The main reason is poor heat dissipation, after overclocking, the processor will heat up greatly, if the heat dissipation is not good, it will lead to a crash, it is recommended to replace with a CPU cooling fan with high quality and strong heat dissipation ability. In addition, you can also try to use CPU cooling software, for example, there is a CPU cooling software called VCOOL, which is specially designed for AMD's CPU, this is a green software, you can run it directly, and only a few simple settings can make the temperature of AMD CPU drop significantly, which is especially useful for the instability caused by the increase in temperature after overclocking.

Another cause of crash is the lack of power from the power supply, and it is enough to replace it with a high-power power supply.
