Btw, my daily for years (sig) on a nice 965BE C3 has been 240x16.5 (3960) with 1.4V under load (via +0.075V offset instead of direct P0 VID, so lower htt oc'd power states are kept stable), CPU_NB 2400 requiring only 1.133V, RAM at 1600 C7-8-7-24 1T Unganged with 1.5V (sticks can do 7-7-7-24 with more voltage, but isn't worth it). It's 24h prime stable, CnQ enabled.
By pushing some extra >150Mhz on CPU and >200MHz on CPU-NB has a huge toll on power consumption without great performance returns, making it hard to keep silent under 60C during summer with a >8h prime stable setting. Over 1,45V heat really kicks. Of course these aren't settings for the spirit of this forum, but for a decently cool+silent 24/7. Average C3s should require a bit more CPU_NB voltage for 2.4GHz @~4.0, but not much over 1.2V; >2600 could require a huge jump in voltage.
If you add a cheap second hand OC'd 7970/280X to your AM3 setup (provided you have a decent PSU), you'll be surprised at how many recent games it can still run decently. TBH, due to CPU bottleneck on racing sims, my RX480 isn't measurably faster than the Tahiti it replaced.
I'll attach for everyone rocking an AM3 a pdf with the multiplier sheet I've shared before (updated with 13X on NB/HT). It's handy to have while on a AWARD bios that doesn't do the math for you unlike the AMI above:
