So I'm stable at 4.7ghz at 1.35v (shows running at 1.36 in system). Max temps after running the sim for a while are in the upper seventies, although average temps are at least 10 degrees less. I'm pretty sure I shouldn't push it any harder, but I'm interested if anyone has a different opinion. BTW I've got a Hyper 212 EVO in push pull with 4 case fans.

Upper 70's in FSX is pretty high but if it's the most demanding thing your computer does then it's fine. You could shave quite a bit off those temps if you replace the stock thermal interface material under the integrated heatspreader, that would allow you to OC further if you desire. More performance is always better, but I don't know how much further you can take Ivy Bridge on air cooling.

I think 4.7 with IB is excellent! I'd stay there... or even go a little lower... try to get the temps to stop @ high sixties when running FSX

I'd back off to 4.5GHz and leave it there 24/7. You should be able to pull that off with 1.33v or so, given what you've achieved so far. You'll notice that the +4.5GHz proverbial lemon isn't worth the squeeze as far as FSX performance goes.

Those temperatures are a bit steep. I would take that OC and Voltage down until your temps are a bit lower.

Dirty lies! 5GHz or bust! :lol:

Hahaha

 

I think that the FPS boost at 5GHZ is more mental than real. :lol:

Lol.

I found it hard to knock my macho attitude when it comes to PC hardware. I finally did, and I've got FSX right where I want it. I started out pushing for 5 no questions asked.

It's just the max temp it hit was upper 70's. The avg is upper 60's. I'm liking the performance a lot at 4.7! Hard to back down down, but I don't think I'll go any higher. Oh and I made the switch to Prepar3d! I would encourage folks to do the same. While it's not a drastic change, there is an improved performance.

He has a 212 Evo ($30) cooler and has pushed it to 4.7Ghz..What was that about IB doesn't OC well? LOL

 

I would say that is better than 5.0 on the SB.

Hahaha

There's a real boost, it's not night and day but hey, the performance is there to be had so I'll take it.

Another 100MHz or 200MHz not going to gain much in frame rate. Unless you can affort frying your CPU, stay where you are or less. Or invest in better cooling and gain a more substantial amount of MHz.
