Overclocking - Worth it?

Recommended Posts

Hey everybody, in normal conditions, I'm happy with my system's overall performance. With heavy thunderstorms and rain (common these days in europe when you fly with real weather... ), my FPS drop a bit though. When building my system, I (at least think so) chose components, that would make overclocking possible (besides the boxed cooler).Does anybody have a comparison from his system (maybe somebody with an i5 too?) that shows if it's worth the risk (loss of warranty and so on), or at least any tips? Any help is very appreciated, thanks!

Hi Jens, Overclock will surely help.One question, i see that you have 8gb of ram, what configuration do you have?if you have 4 sticks of 2gb your overclocking capabilities will be affected.If you have 2 sticks of 4gb then you will have no issues at all. you will need a better cooler I have similar setup to yours, same CPU but different mobo and ram. I could guide you how to overclock, but it is nicely written here http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/1Have a look and let us know if you get stuck.

There's a marked performance increase in fsx when overclocking to the 4GHz+ range.

Looking at your setup id strongly suggest researching and buying an aftermarket cooler.Then OC! those 2500k/2600k chips are monsters, and FSX loves the Ghz.

İ have i5 760 processor OC'ed to 3.8 GHz and it is absolutely worth overclocking it. I did not overclock my 2x4 (8 GB) 1600 MHz RAM and don't know how to it, and i did not OC my GTX460 either. Might overclocking them help me gainerformance?

As long as the ram is at at spec speeds, I'd leave it alone.The 460, on the other hand, can be overclocked in moments with MSI Afterburn utility. Check stability with Furmark.

Thx for the advice sir.

I gained about a 25% increase in FSX performance OC my i5 750 to 4GHz. I left the motherboard (ASUS) voltage setings at default and it changes them automatically, this ended up far more stable than me changing them. I also have no trouble leaving SpeedStep enabled which winds down the CPU multiplier/voltage when it's idling. Download the following programs: RealTemp - monitors CPU core temperatures, OCCT: tests for system stability, MSI Afterburner: nVidia overclocking tool, GPU-z: Monitors nvidia parameters, CPU-z - monitors CPU parameters. Heat is a major factor to watch out for, like other posters have mentioned, you'll need a new CPU heatsink before you do anything. My rig's watercooled, so I just hear a slight gurgling noise at full boost.

Do you get pretty decent performance with your i5 2500k? I want to build a new computer, but I don't want to utilize the cash outlay for a top of the line system. I figured the i5 2500k was a pretty good compromise in terms of price and performance. Thanks. -johnny rodgers

So how much voltage is that motherboard pumping into your processor automatically? I'm sure it's grossly more than needed!Heat is much less an issue with these 2nd gen i7s. I still suggest a descent cooler before trying anything.

I monitored it running OCCT for a couple of hours and the voltages were almost identical to manual settings on the same rigs. My CPU temp never goes over 80 anyway. Bah, now you've made me feel guilty and I'm going to start messing around with it again :(

Haha! If it isn't broken, don't fix it! As long as you monitored the voltages for a while.

Last time I used 'AUTO' for CPUv, I fried perfectly good C2DShocked.gif

See my sig. I am very pleased. Only o/c the CPU and left everything Else alone. My Asus Board makes o/c easy. Just raised The multiplier and that's it. Voltage under load is 1.38. Passed all memtests incl the Intel one

Very pleased with mine running @4.5GHz. Overclocking is really easy with this CPU.

Sooooo,I did it ;-) Just to try it, i used the Automatic Overclocking tool of the board, which took it right up to 4,3Ghz. Had to abort the stability test (I use SETI for that ;-) ) 'cause the temp would go over 80 just after seconds.Promised my wife some icecream in the city, and off we went ;-)Now I have a Corsair H60 Watercooler which keeps it cool and quiet. At maximum load (with OC!) it's 10 degrees (Celsius that is!) cooler that with the boxed cooler and no overclocking.To answer my original question: Yep, it's worth it! FSX seems to run a lot smoother. Funny thing is, it's smoother without external FPS limiting.

Hey guys, I have an i7 920 @ 2.6.I have 2 2GB 1333Mhz Kingston memory but I see it's running at 1066MHz.I want to overclock my i7 with my EX58-UD3R motherboard.Something I have seen is that when I try to overclock from the BIOS the computer never reboots again until the motherboard forces a reboot on default settings.I have tried following different tutorials and so far I can't get it to overclock.Anyone has the same setup as I do? I want to get it up to 4GHz.Regards,Teo

I was wondering how far you could get stable on stock fan...i5 2500k

Just chipping in with another question; what is better to OC: GPU or CPU?
CPU by miles. Overclocking the GPU for FSX doesn't really impact performance in my experience, and may lead to FSX CTD's.

I currenly have 16GB of Patriot Ram (2000Mhz), I can't seem to OC this on a ASUS Motherboard (M4a...) and a 3.3Ghz @ 4.2Ghz CPU. The stock voltage is 1.65, any ideas???

You must have all ram slots occupied, that affects overclocking a lot.Try running with only 2 slots in dual channel mode you should be ok then. some people had some success with all ram slots populated but they had to increase dram voltage sky high to get stable overclock, risky business though, do it only if you know what are you doing, and at your own risk

I have a question about my ex-RAMS.They were 2x2. 4 GB 1333 Kingston DDR3.Now my new RAMs are 2x4 8 GB 1600 MHz Corsair DDR3.Is it OK if I install all of them on my mobo occupying all slots (double dual channel) so that total RAM amount is 12 GB? Since the older ones are 1333 MHz, does it affect overall performance worse and should i use my new 8 GB 1600 MHz RAMs only?
