Hello,
Sorry if the post is too long, but i tried to make everything as clear as possible, and i was looking for a solution over the past few weeks...
the problems is that I'm trying to use SSE 4.1 but PCSX2 says that my CPU does not support it even though at the official PCSX2 guide it says that...
" SSE4.1 supporting CPUs: Intel Core 2 Duo Penryn series (E7xxx,E8xxx and Q9xxx models), Intel Corei3, Intel Corei5, Intel Corei7, AMD Bulldozer/Bobcat"
i checked CPUID to make sure, and here i got confused cause everywhere on the internet (and here in the official PCSX2) it says that my E7400 supports SSE 4.1 while CPUID showed that mine doesn't... i thought that there are more than one version of E7400, one of them supports and the other doesn't but i couldn't find any info regarding other version and when i googled "CPUID E7400" for pictures, I came up with the next photo, which were taken by CPUID for the same CPU as mine and identical specs except for the logo and the SSE 4.1 supports.
THE PHOTO I FOUND USING GOOGLE...
AND THIS IS THE PHOTO TAKEN FROM MY CPU...
i thought maybe SSE 4.1 is not supported by 32-bit operation system, so i tried to use 64-bit windows 8.1 but i failed, and while i'm trying to figure out a why i realized that my CPU does not support CMPXCHG16b, which is a requirement for windows 8.1 64-bit version.
however, while searching i saw someone who was able to have his CPU from non supported to supports CMPXCHG16b after he updated his motherboard bios.
Now i have an update for my motherboard bios but reading about the risks of updating the bios made me wanna make sure it is the last resort, and that SEE 4.1 will be enabled after updating the bios.
So i need to know if SSE 4.1 is not supported by 32-bit operation system, and if it can be activated by a bios update like the CMPXCHG16b feature.
my specs
CPU: Intel Core2duo e7400 @ 2.80 GHz
Motherboad: Gigabyte EP35-DS3L
MB Bios firmware: currently F4 but there is a new version F6
OS: Windows 8.1 32-bit
I appreciate any possible help, and sorry again for the long post.
