MMX working for me?

[nehalmistry]

is there any way to check if mmx is enabled on my system... do i need any drivers or anything... i have had my abd k6 233(ocd to 300) for quite some time now and im wondering if it is optimized for mmx...

i KNOW for a fact that it supports it but what i want to know is if it's enabled??? how do i do this???

Go to c:\program Files\directx and then I think \diag...I'm at work on an NT machine so I can't be sure. There is an application called dxdiag or something like that that will tell you what CPU enhancements are enabled for DirectX acceleration.

Try WCPUID.

Download it from http://www.h-oda.com/

MMX is not something you enable. It's detected, and a program will use it if the program has been designed to do so (sometimes it's in the program's options).

There isn't much else to be done.

Sorry to state my ignorance, but don't AMD CPU's use 3DNow??

Yeah, but they have MMX too. It was a rather funny story about how that came to be. Intel launced their MMX conspiracy, with the intention of hurting it's competators. Then due to an obscure cross-licencing AMD and Cyrux got the rights to use it. Well I think it was one of them got the rights and shaired it. Then Intel stoped pushing it so hard!!

The AMD K6 series does have MMX. Starting with K6-2, AMD CPUs also added 3Dnow.

WCPUID will tell you if your CPU has MMX instructions. All AMD CPU's K6 and beyond, including the Athlons's, have MMX. All PII-III's and some Pentiums have MMX. SSE and SIMD are addition extensions to MMX and the standard x86 instructions.

The reason I told nehalmistry to check the DirectX diagnostics program is because most Windows multimedia aplications (Direct3D, DirectSound(?) and DirectVideo) use DirectX, so checking the DirectX diagnostics would tell whether MMX is being used.

In theory, if a CPU have MMX and an MMX enabled version of DirectX it should automatically enable it for any DirectX function. Some games, like Unreal software mode, will use MMX indepentdently of DirectX, but most new games only use MMX through DirectX.

Thankyou, both directx diagnostics program (dxdiag for win9x) and wcpuid confirmed that i have mmx support... thanx people....
