Edit: It is also nice to have a GOP enabled BIOS for Ultra Fast Boot. But fast boot from an SSD is really not all that much slower.

What is GOP enabled bios?

Was bored and decided to bench my cards. Unfortunately it seems they are showing their age and don't clock as high as they used to, but I still think these old 7950's can hold their own.

Is it worth going 3x crossfire with 8x4x4x over 2x crossfire on 8x8x ? I am having trouble finding benchmarks with similar lane assignment

I'm contemplating testing that this weekend. My sons pc has a 7950 in it. Maybe I'll yank it and do some benching in my pc

That would be great. I can find 3-way benches, but usually the sites doing the benches are on x79, so the lane assignment is beefier. 7970s are so cheap right now it would be a shame to not pick one up.

My config would be 8x4x4. I'll let you know.

nope brother i couldn't find any memory voltage on MSI AB, but sapphire Trixx Modded have. but i only use AB. its stable are more compatible with overclocking.

Voltage over 1.55v seems to hurt the hynix chips in most cases.

Asus released their TOP cards with 1.6v and the memory actually artifacts for many people because of the overvolting.
They actually did this out of spec from the memory's capabilities.

I see people with 1.5-1.55v hitting 1800-1900 in some cases.

Mine does the 1800, but in some games with artifacts with these tiny little checkerboards. VERY strange, and even more common that it is strange.

They did release the BIOS to reduce the VRAM voltage, but even after doing that, I still report 1.6v, and it's hard locked. I can't reduce to 1.5v in AB or with BIOS edit.....


Anybody with an Asus card had this?? (I know I'm a 280x users, but it's the same memory on many cards, especially the 7970 Matrix, which is almost identical.
