My rig: ASUS P8P67 EVO 1155 Step 3 with latest BIOS. Intel i5-2500K 3.3Ghz, w 8GB RipJaws 1600 RAM. CoolerMaster HAF922 case with 5 cooling fans, CoolerMaster GeminII cpu heatsink/fan, Win7 64 Enterprise.I'm looking to OC to 4.8Ghz or thereabouts: as I add more layers to my FSX experience (REX, GEX about to add FSG) I'm noticing a drop in frames, want to keep them at 30+.I followed the instructions here: http://hardforum.com...d.php?t=1578110 and reboot the machine. Running the CoreTemp application, it still states 3.3Ghz as the frequency. I downloaded and ran Prime95, and temps quickly went to 90+ and I started getting overheat warnings. The posts I have read on various forums lead me to believe that a successful/stable overclock would increase temperatues when running Prime95, but not overheat the cpu.I've done various Google searches, searched these forums too, not sure where to start troubleshooting. Should I look at my cooling? How can I adjust fan speeds etc, I thought that was automatic? Is there a utility that will show me the overclock speed the BIOS thinks it is set to within Windows? How can I be certain that the BIOS overclock settings are in effect (I have reviewed them after reboot and they are set as expected, my changes were retained).TIA for any suggestions.

What temps are you getting with stock settings? Idle should be around 20-25C - P95 load shouldn't be much above 50-55C.Before OCing be sure to test your system for stability, test with Prime95 or OCCT for 8 hrs to make sure it's good to go.Anyway with the 2500K all you really need is a touch of vcore (try 1.34v), and set multiplier to 45. Then again, this doesn't work on my rig but I think it's a mobo problem. On your board be sure to enable LLC - and set a higher level if possible.

Ryan, why not try the "Old Style performance" overclock, like Nick talks about here, last post:http://www.simforums.com/Forums/topic39136_post230023.html#230023"disable the power save features on any high performance system, period. Those are office computer features We are not trying to save power.. we want a system that is in a constant performance state for the application"

You can see if your oc worked with cpu-z : http://www.cpuid.com/softwares/cpu-z.html

This has nothing to do with physically OCing the CPU though..He's still going to need to change settings in bios. Turning off the sleep mode/power settings to high performance is fine but won't do anything for OCing.Edit: Unless you're talking about me - I already did all that.

OK, Ryan, but why are you then only at 4.0 Ghz?Oh well, I´ll shut up, you probably know better...

Guys, SB CPUs don't need power saving features disabled to achieve a stable OC, period.That said, I'm running 5Ghz with 1.52V, less and my chip crashes on 3,5hr (100runs, 4gb) Linx test. But hey... don't care about V very much. If it dies, I'll get a new one... And when it's idling, it runs at x16 multi with 1.32V, both C1E and Intel Speedstep activated. And for those S1, S-blah blah modes, those are left on default.LLC is regular. Anything else crashes.And yes, with older CPUS, pre SB, disabling power saving was a big +.

I think Nick means it to perform better, not for better OC stability. My I5 750 was also stable at 4GHz with C1E & EIST enabled. Same for the 1090T system I had before that.

I'd certainly recommend that those with strong Sandy Bridge overclocks use EIST and C1e. Why the heck not? I'd also recommend that he/she disable power management at the OS level, especially with Win7 -Nick covers this in his Win7 setup guide.NOTE!: The above statement assumes you have a rock solid mobo using a rock solid bios. I did have EIST issues with earlier ASUS bios - voltage spikes, to name one.

Dood?!?!?!? Mine runs at 1.000000000000v (The 5.0 volt reading is with Prime95 running with 2 cores)

Yeah dood, we all KNOW you have a great chip. Not everyone is lucky like you!! I tested two chips and both wanted 1.5+ for 5.0.

Word Not Allowed, I was shocked when 1st looked at your 16x idle C1e idle volts. However, I'm now thinking you're running a boat load of + offset, no? Word Not Allowed, I hope you do understand that:-yes, I am showing off the cpu -I'm NOT ripping your enthusiasm to run 5.0, voltages be damned! -I totally appreciate your sportsmanship-And yes, I do believe you know what you doing

Yep, offset is the only way here to lower the volts here and to get it stable at 5.I tried multiple other combinations, if I fix the vcore without an offset, I can't even lower the vcore with c1e. I don't know why, maybe missing something... eist does sink the multi though. So I get it running at 1600 with vcore of 1.5 lol...I know you want to Thank you As do I I know you do
