It helped a little, boot always successful and Aida failed only after 30 minutes instead of 5.
Now i've bumped the ram to 2.0 volts. If still fails then i go back to 1.9 and upping the NB voltage instead.

@lumper NB 1,3-1,4V should do the trick. More RAM = more problems for IMC.

Not to mention now it feels like 60fps and runs better than my X5650x2 rig on this game. It is smoother even on PCIe 1.0.
Will you ever stop with this Opteron ?

Processor: 1 GHz or faster processor or SoC (system on a chip). 64-bit versions of Windows 10 require a processor that supports CMPXCHG16b, PrefetchW, and LAHF/SAHF capabilities. LAHF and SAHF are part of Intel Virtualization Technology (Intel VT-x). For Xeon CPU’s, VT-x was introduced with the Clovertown family. You can a list of Clovertown CPU’s here:

http://ark.intel.com/products/codename/23349/Clovertown?q=clovertown



These CPU’s launched starting in 2006 and any cpu (xeon or Core) that supports VT-x will support LAHF/SAHF; however, it is important to mention that not all Xeon or Core (1st gen, 2nd gen, 3rd gen, 4th gen) support VT-x

This screenshot is on old drivers with GPU Max temp set to 67C limiting clocks. Now I'm on 17.4.1 with 80C max temp on RX 480. Couldn't see OSD in game for some reason but it's running 4x faster now.

LOL, dude, Make a thread like "Opteron ""Prime"" vs ""MegaMod""Xeon" post there and leave a link to your thread here. I Promise some of us will visit. biggrin.gif You may even get others who are more interested in the amd side visiting. thumb.gif

Fail after 22 minutes.
Rolled back to 1.9 volts for ram and upped the NB to 1.26. Fail after 11 minutes.
Then tried to undervolt the NB to 1.18. BSOD in one minute.
Tried 1.22 for the NB but instant fail in Aida. So the absolutely sweet spot for NB is 1.2.
Is it possible that the 2.0 volts were too high for ram and the sweet spot is somewhere between 1.9 and 2.0 or should i look elsewhere?
Starting to give up...

You keep upping 1 while lowering another. WHY? Up the ram to 2.0, AND the NB to 1.26.

You were quicker than me editing the post smile.gif So yeah, because i got the spot for NB.

Windows 10 x64 requires simply a AM2 CPU (90nm rev. F core) or Presler based Pentium 4/Pentium D.
I know, because I checked tongue.gif
Did you checked your info for Xeon's ?

i would call it : battle for budget, Xeon 771 mod vs Opteron.

**-=POLL : Anyone Wanna Chime In On A Title?=-**

This is funny because it's 1 Top Dog AM3 Opteron vs All Of The Many Big Dog LGA 771 Xeon's haha wink.gif

Schuck6566 : -=Opteron=--=Prime=- vs -=MegaMod=--=Xeon=-

Piskeante : Battle For Budget -=Xeon 771 mod vs Opteron AM3=-

AgentX007 : -=Xeon > Opteron=- *jokes* wink.gif
