Thanks for this! biggrin.gif Now I know 4+1 ain't worth it!

Haha, I remember you telling me that you were slightly worried about my mobo and my processor. And now I know what TMPIN2 is on my mobo! It got to 106C a while back just after I unlocked the fourth core, before I dropped the voltage. Now it maxes out at maybe 80ish C.

I only see 4 chokes on my mobo - does that make it 3+1?

Yikes, that's definitely a 3+1 phase there. 106C temp - okay, that's really high! Then again it's not unexpected from high TDP processors on the somewhat weak 3+1 VRMs and near-lack of cooling there. Even though Gigabyte usually features good VRM quality, I never ever recommend 125W on 3+1 phase. That one's not a quality one either actually, looks like it uses the third-transistor design and pretty tightly spaced unheatsinked chokes. That must've been really close eek.gif

890FXE is completely out of the question there tongue.gif

Now, I have some math homework to do... (maybe writing this wasn't so good an idea lachen.gif)

It has 2 16x lanes put cannot crossfire?

Good read. Thanks for this. Now I know...I'm going to back out of my X4 unlock back to X2. Getting a new computer totally though on 2/23/11 for my b'day so I guess I won't have to worry about this soon.

Oh man, I'd believe it. But like I said, undervolting dropped temps a lot. It's been running fine 24/7 since then, but the CPU mostly idles. I just GPU fold on it now.

Added to my sig.
I had to steer my comp tech teacher away from a msi board and a 125 watt chip.
I got him to get a 95 watt chip and an asus with an 8+2.

Oh duh, GXE, sorry. Been a long day.
post #20 of 1100
Im so glad i have expensive taste, got my mobo before this was even widly know, but im sitting pretty with my 8+2. I even go extreme now up to 1.8v etc when doing dry ice runs(my cpu-z voltage detection is wrong BTW, its actually at about 1.785v there).
