Q13: Could Waterfall Pro harm my PC or processor?

Q14: Why is the CPU Temperature that Waterfall Pro reports lower than other monitoring programs?

Answer:

Q1: How does Waterfall Pro's HLT cooling work?

A: They both work with HLT instructions that replace idle cycles with a suspend mode. In other words, when a certain percentage of your CPU is not working, instead of generating heat by processing idle cycles, it's put into a suspend mode, therefore it runs cooler and also consumes less power.

Q2: Sometimes the background in Waterfall Pro's traybar icon changes, but I didn't choose to disable it, what does that mean?

A: The default Waterfall Pro icon is a blue chip. When the chip turns to red, it means that your CPU is 100% in use. When it runs white and has small white dots above it (kind of like if it was snowing on the chip), it means that CPU Throttling is being used to prevent your chip from exceeding a certain CPU load.

Q3: Does using Waterfall Pro decreases my overall performance?

A: Well... the task that Waterfall executes doesn't decrease your overall performance. However, no matter how small they are, Waterfall Pro is a program, and just like any other program, while they're running, they do use some resources. However, the amount of resources that they use is negligible, so the impact on performance is almost null. In fact, with Waterfall Pro you should even experience some performance increase due to its optimization features.

Q4: I've tried several fake performance boosters, how do I know that Waterfall Pro really works?

A: The only way to notice that it is really working is to measure your CPU and/or heatsink temperature. Or if your motherboard has a temperature sensor which is supported by Waterfall Pro then you should be able to monitor the temperature decrease from Windows. Another way of seeing that Waterfall Pro really works is that if you use CPU Throttling it may help you achieve stability with your overclocked CPU.

Q5: I hear some buzzing sound coming out of my speakers when using Waterfall Pro, is something wrong?

A: That's a very common problem. This is not a bug in Waterfall Pro, it's just that some hardware components have weird behaviors when a HLT instruction is executed. This buzzing sound seems to be the most usual problem - although some people think it's annoying, it's actually harmless. In Waterfall Pro you can disable the HLT cooling in the Setup and still use the other features.

Q6: Does Waterfall Pro work under Windows NT?

A: No. NT doesn't need HLT coolers, but we are considering the possibility of Porting Waterfall Pro to NT.

Q7: Why is it that System Monitor and other CPU monitors indicate that my CPU is 100% busy when running Waterfall Pro?

A: That happens because these monitors only detect that a certain percentage of the CPU isn't being used when it's idle. Waterfall Pro replaces this idle mode with a suspend mode generated by the HLT instructions. Therefore, these monitors will always show that your CPU is 100% busy. There's no fix for this unless someone releases a patch for these monitors. Please use Waterfall Pro to see the CPU Usage, because it's more precise than other detecting programs.

Q8: When running Waterfall Pro, I get weird scores under Wintune. Why is that?

A: Wintune isn't a good utility for measuring your system's performance, it's results can't really be trusted. If you run a Cyrix 6x86MX PR200 at 166Mhz and an Intel Pentium MMX at 166Mhz, it'll show exactly the same scores, but we know that the Cyrix CPU is much faster (when comparing Mhz per Mhz). Try using Winbench for a real performance benchmark.

Q9: Can I use Waterfall Pro and other cooling programs at the same time for a better cooling?

A: Waterfall Pro already performs all the tasks that other cooling programs does, therefore if you run both, one of them will be inactive. Waterfall Pro 2.0 is more stable than other cooling programs and it will try to close other cooling programs to protect your system.

Q10: I get weird readings when I use Waterfall Pro's temperature monitor. What should I do?

A: First of all, please be sure that you're using the right temperature sensor module. If you select a sensor that is not actually present in your motherboard you may get weird readings. In case you're sure that you picked the right motherboard and/or sensor, then please contact YiHong Software Development Corporation so that we can try to fix this bug.

Q11: What does the alarm function do?

A: It warns you when it gets a reading from a certain sensor module that is out of the safety range. For example, if you select the "CPU Temperature" warning, it may warn you when your CPU goes above a certain temperature. Or it may warn you when your "FAN Voltage" goes above or below a certain margin.

You may set up several alarms at the same time. For each alarm, you're given the option to select a certain sound so that you can differ them.

Q12: I am a programmer and I want to design a monitoring program that use YiHong's sensor modules. Could I use these Sensor modules?

A: YiHong Software Development Corporation spends a lot of time and budgets to make these sensor module protocols and design these sensor modules. If you want to develop your monitoring program and want to use our sensor modules, please contact us. Or you should not use them.

Q13: Could Waterfall Pro harm my PC or processor?

A: No, Waterfall Pro won't harm your PC or processor. However, some low-quality mainboards that use cheap components may cause your system to be have some weird, but harmless, side effects (such as a buzzing sound coming out of the speakers). If your computer crashes when using Waterfall Pro, please contact your hardware manufacturer and tell them that your mainboard has this problem.

Q14: Why is the CPU Temperature that Waterfall Pro reports lower than other monitoring programs?

A: Because the CPU Temperature is higher than the actual temperature which is detected by the sensor chip or sensor components, some monitoring program will add compensating values in CPU Temperature. But we believe that compensating values are not very useful because they're generating an artificial number, so our sensor module will not add them.

4. Setup: Instructions on setting up Waterfall Pro

Setting up Waterfall Pro is very easy, but requires that you read our setup guidelines and follow every recommended steps. By reading this section, you will learn how to use it, and find out how Waterfall Pro can improve your computing experience.

When running Waterfall Pro for the first time, or whenever you wish to update your configuration please click Waterfall Pro's task bar icon (it's one of those small icons which are placed next to the clock in the lower-left part of your monitor). By doing this you will open Waterfall Pro's main window.

The Main Window

STEP 1:CPU & Mainboard Setup

Now click [Option] and [Setup] to enter setup mode. When you enter setup mode, you will see the following Window.

Setup / CPU& Mainboard Setup

You will be asked to input the name of your CPU. This information is usually provided by the company who assembled your computer. However, if you don't know which CPU you have, then don't worry, just select "Generic Processor". In that case, Waterfall Pro will try to figure out the best settings for your CPU. But please note that for the best performance, it's advised that you try to find out which CPU your computer has.

After choosing your CPU, you can input its core voltage. If you know what type of CPU you have, but don't know what voltage it uses, please go to the Appendix D in this manual. Otherwise, just leave this setting unchanged.

Then you can choose your mainboard model. If your mainboard is not listed in this list-box, or in case you don't know which mainboard you have, please select "Generic Mainboard". Unfortunately, however, you can only use Waterfall Pro’s monitoring and alarm functions if you specify your mainboard. If your mainboard isn't listed yet, please contact your mainboard manufacturer or wait for a plugin module to be published at our website. Due to the amount of mainboards in the market, we can't offer support for all of them. But Waterfall Pro will still works properly even if your mainboard isn't listed.

Once you have selected your mainboard, the "Setup" button next to it may become visible. This means that your mainboard has a lot of optional hardware sensors. In that case, just mark the ones that you would like to use.

STEP 2:Alarm

Now click the "Next” button to set up the alarm settings. You will see the following window:

Setup / Alarm

Waterfall Pro's exclusive Alarm system can notify you when something in your system is abnormal. If your CPU Temperature is too high, you can using these setting will start CPU Throttling (the CPU Throttling feature is explained further in the manual) to protect your CPU.

Setting up the Alarm system is very easy. Use the "Alarm" option to select which Alarm system you would like to configure. After configuring an Alarm system, you can choose another one and configure it as well, this way you can set up an unending list of Alarms that will always warn you whenever something abnormal occurs.

After choosing which Alarm system you would like to configure, you can also define a safety range by setting the limits thresholds. For example, I can make Waterfall Pro activate the Alarm in case the CPU temperature is above 60C (Upper Safety Range) or below 20C (Lower Safety Range).

You are also given the option to play a sound when the Alarm is activated. You can even set up different sounds for different Alarm systems.

If your mainboard has a sensor which is recognized by Waterfall Pro, you can choose "Decrease the temperature of the CPU when its overheated" . This feature will start CPU Throttling when your processor is overheated.

If you want to use default message and safety range which be defaulted by sensor module, you can click "Default Message and Safety Range". This feature is very useful if you don’t know how to set safety range and message.

STEP 3:Miscellaneous

You're only advised to change the settings in this window in case you're an experienced user.

In this window you will see one of the best features of Waterfall Pro: CPU Throttling. You can learn how to use CPU Throttling to protect your processor from overheating. It is very useful for laptop users and overclockers. You can move the slider bar to set the percentage of the CPU Throttling. By changing the CPU Throttling settings, you're able to select your CPU's maximum load, which prevents it from exceeding a certain temperature. The lower the maximum CPU load, the lower will be the maximum temperature and power consumption that it will achieve. However, CPU Throttling has an impact in your computer's performance (which is not very noticeable for high levels of maximum CPU load), so it's up to you decide which setting best fits your needs If you are laptop user, we recommend you to set CPU Throttling to 50%.

If you want Waterfall Pro cool your CPU, please check "HLT Enable” (cooling the CPU through HLT has no impact in the CPU's performance).

Setup / Miscellaneous

STEP 4:Additional Modules

Now click the "Next" button to move to the next step.

Setup / Additional Modules

In this window you can select up to two additional modules for Waterfall Pro to monitor. Some modules may require setup, in that case, the Setup button next to it will become visible. If you're using an additional module that didn't originally come with Waterfall Pro, please refer to the module's own documentation. All modules that come with Waterfall Pro are straight-forward and don't require setup.

So, all you have to do is select which ones, if any, you would to monitor.

Now click the "Next" button to finish setting up Waterfall Pro.

Step 5:Finish setting up Waterfall Pro

When you finish setting up Waterfall Pro, Waterfall Pro will optimize your system. If you chose the wrong type of CPU in the first window,, your see a blue screen error. Please don’t worry, this doesn't make you lose your current work or harm your system. Our reliable Secure Optimizer prevents your system from crashing.
