dont know if this will catch on. but i figure a lot of places have a thread like this and may help someone in the future. ive been playing with my cpu and started to overclock just because. said cpu is a phenom ii x4 975 be, so far i have it prime95 stable at 4.027GHz with a peak temp of 52.1*C (kinda worries me)

http://valid.canardpc.com/2651900

20x201 @ 1.425v

air cooled with Silenx 120-HA5

Ambient ~73*F

Guess it's abit of an epeen thread but ohwell, got my 3570k @ 4.6ghz with 1.275v. I can't get it prime95 stable at 4.8 without bumping vcore to 1.350v which I don't really wanna run for 24/7


*EDIT* Forgot specs:
i5-3570k
Asrock z77 Extreme4
Noctua NH-D14

Load temps of 65c
20c ambient

Keep in mind Phenom IIs have a strict heat wall. I think 55c is the absolute maximum stable temperature, with no play in that in either direction. 52ish is okay, but it won't stay okaynif the ambient temperature in the room up.

[Staplebeater]

only moderate sized epeen here. 2500K OCed to 4.2 GHz with a Cooler master hyper 212 cooler

ya, def a bragging thread and maybe some info for others.
dam, dude. thats crazy. i wish AMD's were heat efficient

Really? i thought the max temp was 62*c?

[Kaptain]

I think it is 62*C...

One of my clunkers (FrankenComp)
965be on an OLD am2 board @3.8
cooled by an old zalman 9700 I had laying around.
Can't set OC in bios (125w) must be set in windows with phenom tweaker.

The 965 Breathed new life into an old system. Purchased a gtx280 to complete it. Undervolted and overclocked I'm getting about 35 FPS on high @1600x1000

OCing is soooo much fun

My Siggy

Twelve Hours Prime 95 Stable, Tripple 120mm Rad, Haf 932. CPU 65C (Core Temps never exceeded 90c). TJmax for this chip is 105 per core. Don't do much with it, but it's been three months of flawless game play. Going to delid it in February.

best OC screenshot I have handy, not my highest stable OC. Been as high as 4.9ghz, WCG crunching stable

[Sen]

I've taken my 3930k all the way up to 4.9 @ 1.35v [previous to last BIOS update] Load stable all day long, just don't let the stupid thing turn the monitor off, or it'll freeze sure as shi'ite.

Godly processor, tempermental SOMETHING I don't feel like running down [suspect a borderline ram stick]

[Aznpersuasion89]

while i was playing around i noticed that my cpu temps seems kinda low for me and overclocking. right now the ambient is like 74*F and im getting peak around 53*c while running prime95 at a 3.9 ghz overclock. i decided to check what amd overdrive said and it said 62*c! but also idle (800mhz) was 43*C? im thinking that amd overdrive is on crack. cooler is a push pull with 2x120 mm fans.

EDIT: downloaded coretemp and it agrees with open hardware monitor, so im thinking AOD is on crack

[Aznpersuasion89]

so when i go into the BIOS and enable core unlocker it disables core temp reading. why would it do this? makes it hard to overclock and not melt anything.

EDIT: figured out core unlocked does not need to be enabled in order to overclock. can now see temps again

A question for you overclockers....is it worth it?

I recently bought a 3570K and Im running it stock. Perfectly happy with my performance in MWO, its very smooth. Would I notice any significant difference if I decided to to clock it past 4Ghz or is it overkill for this game?

Highest Stable overclock i have managed, temperatures were in the ok range, i just could not bring myself to keep the voltage that high.

I have my Phenoms heat up to 66° or even 68° Celsius and run stable as rock for many years.
But the heatsensors be in general faulty and may show temperatures with a ~10° difference to the real ones.

Overkill, I'm actually running my 2600k at 3.8(stock with turbo boost) and I don't notice a difference. A higher-end Piledriver, Sandy Bridge, or Ivy Bridge cpu is plenty at stock speeds for gaming. Core2Quad, Phenom II, and Bulldozer CPUs would benefit from OC'ing when running MW:O

Well, you could have saved money and gotten a normal 3570 if you didn't care to overclock. The point is to increase stable frame rates, specifically in reading minimum frame rates during crazy brawls with a lot of effects going on at the same time like in River City. Have you been using the F9 key?

[KerenskyClone]

Aha so I would benefit from an increase in the min frame rates, well since I havent noticed any significant drops I guess I could start using the F9 key. Alhtough looking at frame rates while brawling is rather.....distracting...

I did buy the K with an intention to overclock 'eventually' as in if and when I need it also it was marginally more expensive so it was a no brainer...

is it worth it? sure, usually a free boost if you already have a good cooler. now is it necessary for me? definitely not. so far im still GPU bound with crysis 2 on ultra with the quality mod. its really just a thing to do it just to do it. im also overclocking my gpu right now to, just to do it.

Therein lays the problem. Monitoring CPU temp is something we can do with only limited accuracy. Most temperature-monitoring programs have a calibration setting for that reason, but of course, few of us ever have the calibration data to use it.

55C was usually the number batted around a number of prominent Phenom II OC guides for a number of years (see Dolk's well-known guide, for instance), but temperature programs have limited accuracy, and of course, AMD may well have made some subtle silicon improvements with later batches of processors since such guides were written.

"Worth it" is a very subjective kind of phrasing.

Will you see a difference in any of today's games? No, almost certainly not. A stock 3570K won't be a bottleneck to almost any system, almost regardless of game. Down the road, however, it may net you tangible performance increases. It's just like my old Athlon 64 3700+ (San Diego); it was more than fast enough for any game that was around when I bought it, but later on, as it aged, I milked a good deal more life out of it with a budget liquid cooler and an OC from 2.2 to 3ghz.

[TheFlayedman]

A stock 3750k is a bottleneck to MW:O now. Just look at the performance charts that wete lifted from the russian site
