Hi guys, after my SB upgrade (for details see sig) I tried FSXMark11 for the first time today with an oc of 4.3 GHz. because of the fact that I´m no expert with overclocking I left the BIOS itselfe oc it. 4.3 are stable since 2 days. So I thought giving FSXMark11 a try and see what results I get. The results were worse. After some tests I got an average of 10 FPS. How can that be? Is it because of my pritty old GFX card? May this be the culprit?Another thing regarding the oc. I just tried to get 4.8 GHz but no avail. It booted and windows worked, but the heat is enormous. With BurnTest I got 95°C on all 4 cores, even with my not that bad aftermarket cooler. Currently I have it clocked at 4.5 with more or less 80°C in BurnTest and prime95. Allready a bit too high. maybe I´ll clock it down to 4.3. These setting seems to be currently the best. How do you guys keep your CPU cool even at high clock speeds?

Auto voltages are always higher than actually needed. Try lowering vcore manually until you experience instability in stress test, then up it a notch or two, and see what temps are.Otherwise I'd recommend the painstaking task of studying up on OC and do it all manually. There's tons of tutorials out there. And there may be specific tweaks and advice for your particular mobo, so look up on that too. Good luck!Bjorn

You should not overclock until you have tested your system throughly on stock clocks to begin with. Do not use Auto Tune, listen to PFL here and do your homework! It's really not that hard and we will all help you in everything you need to know.1.- What's your full load Vcore? 2.- How did you install the cooler (orientation, where did you plug the fan(s) to)? 3.- How many fans does the Mugen have installed and what speed are they running?4.- what TIM did you use, how much and how did you apply it? 5.-Do you have better temps if you remove the side cover of the case?

Steffen,There's nothing wrong with your cooling. Your temperatures are so high because Intel Burn Test (IBT) now takes advantage of the newest instruction set, AVX. A custom water cooling loop is the only thing that will keep temps down to a reasonable level - and I'm not even sure how well that will handle it. Regardless, you do not need to worry because nothing right now uses AVX and even if anything did, it's not going to stress your CPU like IBT. I would recommend prime95 for stability testing instead (use blend).If you see 95C with prime95 as well, let us know, but I'm 99.9% confident it's just the AVX with IBT.

Hi Stephan; I'll repeat PFL said, with a little more emphasis: (just to make sure you hear us :Talking Ear Off: )NEVER, EVER, overclock with your main CPU voltage, your memory controller voltage, or your main memory voltage on "Auto". This is the absolute #1 best way to kill a proc and/or your memory dimms.When the core temperature reaches TJMax, the Intel docs say, "the processor has reached its maximum safe operating temperature." It doesn't start to thermal throttle until it hits TJMax - which can vary from one CPU to the next. Sandy Bridge CPUs seem to be set to 98C, with Intel setting the THERMTRIP thermal shutdown temperature to TJMax + 25C. Overclock like this guide indicates, here,and for some greater insight go here.Your Muggen should be fine, as the 2600K is a pretty cool proc compared to the 9xx series. I clocked to 4.2 with the same cooler as you have, but changed to water to go higher, so this 2600K just inherited it.

Thanks for your ideas so far. I´ll gonna check them as soon as I can. Does someone know a programm which shows the fan speeds?

Good catch Corey! let's hope it's just AVX@Steffen, you can try Speedfan for the chasis fans, and for the CPU fan look for Q-Fan in your BIOS (under Monitor I think)

So far I restetted everything back to default. This guide you´ve linked is relly good. I think I´lll gonna do it the way they say. In this guide they say soemthing about RAm oc and timings. I´ve seen that my RAM has an X.M.P. profile. Isn´t it better to enable this in the bios rather than setting the RAM up by hand? Currently it´s running at 1333MHZ and CL9-9-9. But with X.M.P. it´ll be CL7-9-7.They also say that I should get the newest BIOS version. I´m currently on 1506 version. Is this a good one or should I do an update? Hopefully I get it running on 4.5GHz today so that I can set up the rest of the sim tomotow.

Hmmm... Learning by doing, and by errors here I guess!Don´t use XMP when manual overclocking, it tends to overvolt, and you really do not need that, again, right?BIOS update? Yes, if it fixes something that needs to be fixed, read the comments on the Asus support/download page..

Just a side note - - many current guru's, including NickN recommend using OCCT to stress test your clock as it relates more to what the system will run into using FSX than the typical Prime95 tests. If you can run OCCT for 1 hour wiht no issues and keep temps down, you should be good to go.Vic

Today I did some oc. With the settinmgs from the guide from http://www.clunk.org...-beginners.html but they were unstable even on 4 GHz. Every boot was followed by a BSOD, so I gave this version up. I currently try to get a 4.6 GHz oc nailed. This are my settings:AIOverclock Tuner: ManualBLCK Freq:100.00TurboRatio: Enabled (All Cores)By AllCores: 46InternalPLL OverVoltage: EnabledMem Freq:(AS PER YOUR RAM)EPU PowerSaving: Disabled Load-LineCalibration: RegularVRM Freq:Manual Set to 350PhaseControl: ExtremeDutyContorl: ExtremeCPU CurrentCapability: 100%CPUOverVoltage: Offset ModeCPU Offset:+ 0.070DRAMVoltage: (AS PER YOUR RAM)VCCSA Voltage: AutoVCCIO Voltage: AutoCPU PLL Voltage: AutoPCH Voltage: AutoCPU SpreadSpectrum: DisabledCPU Ratio:AutoIntelAdaptive Thermal Monitor: EnabledIntelVirtualization: DisabledIntelSpeedStep: EnabledTurbo Mode:EnabledCPU C1E,C3, C6: EnabledThis setting is one of the ones you adviced me to use. But I´m a bit dissapointed about the temps. With prime95 I got temperatures arround 85°C and the Vcore went up to 1.344V whereas the guy who wrote this settings says, that this should give 1.3V max and 70°C.I´m currently checking this setting with OCCT because someone said that this refleckte the FSX demand better that prime95.Update: The system passed the OCCT test without any error. The highest temp was 86°C ( I think this can be a bit lower) but it seems to be stable. Maybe I get lower temps if I scale down the Vcore but I´m a bit unknown with the offset. What do I have to set to archieve a lower vcore than 1.34V? Another question: What is the latest BIOS version?

Looks OK, but try with these corrections:Load Line Calibration: Ultra High Offset Voltage: 0.020 C3, C6: Disabled CPU Power - Additional Turbo Voltage: 0.016 I don´t understand your temps, there must be something wrong... I have a cheap Coolermaster Hyper 212+ with one fan only, and my temps are max. 73 C - load with Prime, and max. 66 C in FSX...Maybe check if your cooler and paste is mounted properly?

Thanks for the additional settings. I´ll do that tomorow. The thermal paste is "Arctic Silver 5". I´ve heared that this is a very good one, so the temps should really be a bit lower. But this is a good tip. Maybe I did too less. How much should a apply do the CPU? I´m not sure after I drowned my last CPU with tonnes of paste.

A very thin layer should be applied, difficult to quantify...I usually make a Z of the paste on the chip, then spread it evenly with a plastic gloved fingertip. Some of the applied paste will come off in the process, of course. I make sure to earth myself before touching the chip. I know some would just put some paste on the center and let the squeeze of the heat sink spread it out, but I like to see it guaranteed evenly distributed. Other methods, anyone?!Bjorn

I preffer the usual rice grain size drop in the middle of the CPU, and let the pressure spread it. Steffen, too much paste is a bad idea, not only because it's far less effective, but also because if the TIM spills into the socket you're going to be in deep ######

My method (which has proven to work each and everyone time till now):A nice long line of paste on one side of the chip, take a credit card, and pull it to the other side, do the same thing 4 times around, while the whole time holding the card at the very low angle. Then in the end, with a little pressure, clean side, pull with the card above the chip scraping off if there is too much (there always is).In the end, put the cooler on it, and then keep turning it couple of times, if possible circular (I can move mine about 2mm in all directions when screws just in, but not tightened).

I agree with the rice grain method. If you have never done it, I would highly recommend doing a few applications just to get a feel for how far the paste spreads with how much you apply. The only problem I have with spreading the paste is that it's very likely you will have air bubbles - and those aren't so great at conducting heat.

As far as suggestions from OC guides, I have read around that the B3 boards require more voltage in general. So perhaps if you're reading a manual that was written before the whole B3 shenanigans, it's going to suggest lower voltage than what you can run.

What I gather out of this video, the best method is a cross? I have always been running successfully with a thermal compound spread over the whole CPU and then just slide a cooler a bit to get the air out as much as possible. I really have no idea if it works properly, but my temps are OK.

I am with Dazz on this one. It's probably the reason your CPU temps are so high. I mean re-consider the whole cooler installation.Gerald R.http://www.multicrewxp.com

I´m giong to make the adviced changes in the BIOS and then a qiuck test how the temps behave. If the lower voltages don´t bring it down, I´ll have to think about my cooling concept again. Btw. what´s about the RAM? Currently it´s running on 1600MHz and CL-7-9-7. Is this ok or should I speed up the RAM a bit?Update: Just made a little OCCT test with the new setting. The Vcore was aweful high, about 1.4V and the temps got a bit hotter. Thery were in the range of 82-92°C. I´ve encountered one strange thing through the tests: The first core is always the coolest whereas core#2 is the hottest. Is this normal?Going to revert to the old setting and readjust the cooler. Then I´ll hopefully get the right temperatures.

Reverted back to the original setting. The Vcore is fine now just below 1.35V and the temps were between 80 and 85°C in a 10 min OCCT test. Now I try to do some FSXMark11 tests and check the temperature in FSX.I´m currently on testing in FSX. Sinnce I´ve installed and activated the new installation, my one is also working as it seems to be activated too. I don´t know why but I´ve lost my whole Scenery.cfg and the FSX.cfg, so it´ll be a long way till I´m fully setted up again. Also the temp´s are quite good. The highest I´ve noticed with realtemp running in the backround and flying with the default/OZx Bell 206 over PNW were arround 70°C. I don´t know why they now are that deep and it I use OCCT they´ll go up to 85°C.

Last OCCT test gave me temperatures of about 72°C at it´s highest. I did test it with case open and with case closed but the temperatures din´t change that much. Just to make sure that there isn´t a heat jam in the case. All fans checked and they´re correctly installed and setted up. Could it be that my high temperatures were because of the fact I´ve choosen "Silent" as the CPU fan´s mode in the BIOS? Now it´s running on "Standard".Another thing about the BIOS. In the past I had twice the problem that the system won´t wake up from sleep until I clear the BIOS via removing the batterie. Does a newer BIOS version corect that issue? Btw. I´m using version 1502.

please Steffen, answer these questions (the ones you have not answered already)

1.- What's your full load Vcore? 2.- How did you install the cooler (orientation, where did you plug the fan(s) to)? 3.- How many fans does the Mugen have installed and what speed are they running?4.- what TIM did you use, how much and how did you apply it? 5.-Do you have better temps if you remove the side cover of the case?

Sorry dario that I hadn´t answered them earlier.1. The Vcore under full load varies between 1.328 V and 1.344 V.2+3. See attached picture. Maybe a push/pull-config might help?4. I used Arctic Silver 5. Applied it in several lines on the CPU and tried to spread it with the peak of the injection the TIM was inside.5. Made a test with removed cover and the temps were in the range of 74-79°C._MG_0039.jpgBtw. Just run OCCT again to gain the Vcore and the temps were again up tp 87°C. In FSX I had a lot lower temps of 77°C or less.
