What about modding your BIOS?

Not sure your point. Modifying the BIOS is totally different from making changes to the OS via the Registry. Changes you make in the BIOS are not permanent until you "Save and Exit". And of course, every motherboard user guide/manual explains in detail how to reset the BIOS. Some motherboards even provide a simple rear panel BIOS reset button just for that purpose! And many motherboard makers provide easy methods to backup and restore the BIOS from backup.

So making changes to the BIOS is not the same thing as dinking around inside the Registry.

I'm sorry if I didn't make it clear... what I meant by modifying BIOS is... by unlocking it and unlocking settings and reappear the hidden settings that supposed not to be there for the consumers market because if it was there.... NO BODY WILL BUY A NEW LAPTOP AGAIN!!! see what I mean?? so... doing that will get my laptop bricked but thanks to SPI BIOS Programmer.. I do the impossible on a laptop and what I mean bricked laptop.. I mean that you can't even turn on your laptop.. it is just dead.. so... yes... editing the registry is like drinking water to me... what is a real challenge is playing with the BIOS... a Windows without BIOS is nothing but a piece of junk... remember I am using a laptop not a desktop... it is two different worlds... we don't have a rear panel BIOS reset button like desktops.. so... you now you see what I am talking about

Sorry if I got out of topic but I guess techpowerup forums seems to be much more biased to desktops than laptops so... I fully understand when somebody doesn't know or have a very deep knowledge about laptops

That is still a totally different scenario than editing the Registry.

And sorry, but it is just wrong (if not a bit condescending) to assume less interest in modifying notebooks suggests a lack of understanding or knowledge about laptops. And IMO, the word "bias" suggests an "unfair" favoritism towards one party over another. That is not the case. Just because many of us "prefer" to build our own non-proprietary PCs (with full sized keyboards, mice, monitors and surround sound speaker), that does not mean we are "biased" against proprietary notebooks.

And of course people will still buy laptops again. I am afraid you have a very narrow, tunnelvisioned view of the laptop market. First, by far, the vast majority of notebook buyers have no interest in modifying the BIOS. As I said above, "most notebooks are used as mobile devices for personal business, work or school." That is, NOT play. And the greatest demand for such devices in the future will continue to be by those users.

What is "unfair" is the lack of an ATX type form factor standard for laptops. That leads me to this point - laptops tend to be very proprietary with proprietary BIOS settings, that have already been heavily modified by the notebook makers. They also have proprietary hardware and often proprietary modifications to the OS and other installed programs. While some factory built PCs may have some proprietary modifications, most are minor and easy to overcome. And of course there is a HUGE self-build PC industry that allows us to put an ASUS motherboard inside a Fractal Design case today, then swap it out with a Gigabyte board tomorrow where we expect the same case and same power supply and even the same Windows will support it.

So no, modifying the BIOS is for a different discussion/thread.

It probably should be mentioned how exactly this is supposed to be done. As a measure of "harm reduction".

It basically started in this thread here. With a link to this article here. Which, in general, outlines the process of adding the "requisite" DWORD (32 bit) values to the registry. What's changed from that thread, and said article, is the supposed definitions of the DWORD (32 bit) values(as in what they really do...supposedly...and the addition of a couple that weren't mentioned previously) and the value data that "should" be applied for each. The new hypothesis supposes that a value data of "0"=OFF and "1"=ON. Which may, or may not, be correct(I don't know).

In summation:

1. Open regedit.
2. Go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
3. Add the following new DWORD (32 bit) values:

FirstLevelDataCache
ThirdLevelDataCache
FourthLevelDataCache
FifthLevelDataCache

4. Modify the value data in decimal base for each of the above to 1.
5. Also modify the value data in decimal base to 1 for the following DWORD (32 bit) values:

LargeSystemCache
SecondLevelDataCache

6. After which a system restart is recommended(not sure if it's required).

Then decide for yourself whether it was all just a waste of time, or not. I hadn't noticed any issues present themselves by editing my registry in this manner. But I'd definitely not seen any benefit to doing it either. So I went ahead and deleted what I'd added, and modified the values I'd changed back to their original states(as in back to "0"). No harm, no foul...I guess.

Couldn't agree more... thanks for your honesty

I can't edit OP, so lemme update what DWORD values mean, as values in OP are incorrect:

0 = not system managed
1 = automatic delayed start
2 = automatic start
3 = manual start
4 = disabled

SecondLevelDataCache value in the memory management section of windows the value is based on the size of your SecondLevelDataCache your cpu has installed.

I've read books where setting DisablePagingExecutive and LargeSystemCache to a value of 1 will improve performance.
