Help with O.C.

[SicKlown42012]

I just got a new system put together.
Went with Phenom 2 940Be @ 3.7(200*18.5 1.5V) With Zalman 9900
Asus M4a70 Deluxw Mobo
8GB G.Skill 1100 @ 1067 5-5-5-15-32 1.9V
GTX 260-192 SP( already had this)
Antec 1200 with 7 fans

My question is this. Is my cpu voltage safe for everyday use? I tested iwth Prime95 and OCCT and never saw my core temp go over 52, usually hanging around 49. As you can understand, i don't want to blow my new toy up before i get a chance to enjoy it. Thanks you any answers and advice.

Edit: Wasn't quite stable at 3.7, so I've dropped it to 3.6 and brought the core down to 1.45. OC'ed the NorthBridge to 2.6 to try and make up the differnce and am running Prime95 at the momment

1.5v is not to high with the temps you were running.
At 3.7Ghz CPU speed I would run the CPU-NB at 2.4Ghz @ 1.25v and the HT at 2Ghz @ 1.22v.
At 3.87Ghz my CPU-NB is 2.5Ghz @ 1.25v and my HT is 2.25Ghz @1.24v

just bump the voltage up to 1.55v @ 3.8ghz prime test it.. if its stable go back and drop it down 1 setting.. check again.. do this until it becomes upstable again.. then raise it back up 1 setting and that will be the lowest stable voltage you can run at 3.8ghz.. ya have to remember these arent c2q 45nm processors they arent as sensitive to voltage and actually overclock better with lower temps then they do with higher voltages..

Thank you for the answers and suggestions. When i get some more time this weekend, i'll try to see if i can hit 3.8. One more quick question though. I know that these Phenoms aren't really memory bandwith starved, so just how much improvment in real programs will i see from upping the NorthBridge speed?

Actually as you increase CPU speed you MUST raise the CPU-NB speed to maintain enough data flow to the cores and the L2 & L3. To run the CPU at 3.8Ghz speeds a CPU-NB speed of between 2.4 and 2.6 is all that's needed @ 1.22v to 1.26v. It also helps to raise the HT slightly, no need to ever go above 2.2Ghz.
