Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Investors seems to disagree with your statement that "things didn't go so well"
The loss was the result of having to pay to get out of the GloFo arrangement and the purchase of Sea Micro. Excluding those one-time items, AMD did quite well and beat analyst expectations.
That first paragraph sounds like an actual answer, followed up by a second paragraph copy/pasted from the marketing department before AMD realized that no one was buying the 'maintained IPC' claim.
And your second statement doesn't make sense. If someone said that, they don't understand what...
It's pretty commonly accepted that IPC refers to instructions per clock for a single core. I don't think I've seen anywhere that uses it in the way you've described.
I would give the new BIOS a try if it's not too much trouble to throw a Deneb back in there to update.
I was using F9 on my 790X-UD4P, which was released in November 2009. It failed to get into Windows with that BIOS. Upgrading to F10C solved the problem.
F7 for your board came out in...
Haven't had a chance to use it too much yet, but I ran my 720BE at 1.65V for a while and it wasn't fully stable with 4 cores anymore.
So I effectively went from X3 at 3.3GHz to X4 at 4.2GHz. Pretty noticeable difference, but probably not worth the money unless you get the other cores to unlock.
What board are you using? Do you have the latest BIOS? I had the same issue going from 720BE to 960T, and it was because the BIOS I was using did not support the 960T. Updating it fixed that issue.
I appear to have gotten a pretty 'meh' 960T... can't unlock any cores and needs 1.5V to do 4.2.
At 1.5V temps start creeping up to 60 unless I set my H100 to its fastest speed, and that's a little loud for my tastes.
I'm doing the exact same upgrade as you (720 x4 at 3.4 to 960T) so I'll let you know how mine does when I get it Friday. My 720 has been really unstable all of a sudden - maybe something to do with running it at 1.65V for the past few months.
Motherboard is a GA-MA790X-UD4P and cooler is H100.
