Hello Everlong18,

Yes I did upgrade the BIOS for the motherboard. Is there a way to tell for sure what version Bios I am running. I have a evga 780i sli motherboard.

Thank you so much,
Riverswild

But if L2 cache is managed by the CPU and not by windows then I guess I have nothing to worry about. I am very new to this and this is my first computer build. It is very nerve racking for me.

Thank you so much for your reply and help!!

I wouldn't worry about what Windows think about your cache size, as long as it's seeing all your CPU's (cores), as noted above by Everlong18.

I do not know what kind of detect methods 3dmark06 uses for CPU / L2 cache. If it's just spitting back the data that Windows provides it... well...

You might try upgrading it. Downloads links: Futuremark - Benchmarks

Your BIOS probably has an option in it for detailed information on boot. If you enable that, it should print out the L2 cache size on bootup.

It's worth pointing out that if you replaced your original CPU with a new one that is a different model Windows can become "confused."

Example: I "borrowed" the CPU from a new machine at work for my own workstation. My Pentium-D (dual core) was suddenly a Core2Quad. The BIOS saw the new CPU correctly. However, Vista's device manager thought I had a pair of Pentium-D cores and a pair of Core2Quad cores.

My solution was a fit of rage where I wiped the harddisk just to teach it a lesson. Things worked great after re-install!!

Probably better solutions out there.

Sorry it took so long to reply. I was looking in my bios for the option you had mentioned but I couldn't find it. My devise manager does see all my cpu cores. I also built this computer with all new hardware and then installed windows. So, everything should be fresh. I have no idea. Seem weird to me.

Thank you for your help!!

Hello, one more again.

This is very difficult but I will try to do a good question.
My memory cache have 4096 KB, and by default my memory cache only uses 256 KB of storage, right? (Says in the tutorial)
For I use the full potential of my memory cache i need to follow the tutorial, isn't it?(if i need)

So when i go to the second step(regedit) what i have to do, is replace the value 0 for 4096 (decimal) or 1000 (hex), this is right?

Thank you, for your help.

Hello Akuanauta,

Since your CPU has a 4 MB L2 cache, then yes that would be correct.

Good evening everyone. My processor is a Intel Pentium Dual core T3200 @ 2.0GHZ and I was skeptical the settings required to utilize the tip.

I fooled with this tweak on a Q6600. I don't think I am going to use it. But, it is very interesting.
