Overclocking - it's definately worth it

Recommended Posts

Hello,A few days ago I got my new motherboard (MSI P55-GD85), because I couldn't overclock my old one. My CPU is an i7 860 @ 2.8 GHz.This MSI motherboard is very useful, because you only have to change the CPU base clock in the BIOS, and it automaticly adjusts the CPU VCore for you to the optimum setting.In this way, I already overclocked to 4 GHz, with a Scythe Mugen 2 Rev B CPU Cooler. With FSX running, it's about 50C. That's pretty good in my opinion.And now the performance:WIth the CPU at stock speed, I could run Aerosoft Schiphol and the NGX at about 12-15 fps with almost maxed out scenery, 50% traffic. Now with the CPU on 4GHz, I can run this at 20-23 fps on even higher settings!And that all cost me about 220 euros. So if you're thinking about overclocking and/or buying a new motherboard, I can tell you, it's definately worth it!I highly recommend the MSI motherboards, because they are very good to overclock.Don't do it with the stock cooler though!Happy flying,

Yep, I have an i7 920, overclocked to 4GHz, have had it at 4.2. Would hate to have to run FSX at stock CPU frequencies. Best thing I ever did was overclock my i7. I use a Noctua NH-D14, absolutely awesome cooler and super quiet. Although I believe the Silver Arrow now beats it a tad. And the H100 slightly at very high clocks, if you don't mind a jet engine at max rpm in your enclosure, that blows your eardrums. Martin Wilby

Just got my 2500k, performance is great! I haven't over clocked as yet though...
I OC'ed my 2500k on an Asus P8z68-v to 4.5 GHz using this video as a guide:
With my NH-D14 it never gets hotter than 70 celcius. It ran great at stock speeds, but the motherboard's built in OC feature, my computer would restarted two or three times every time I'd boot it up, before it'd settle down and start up normally. OC'ing manually as per the video made everything stable and nice.

I don´t know anything about overclocking...I have a i5 650 @3.2 ghZ. Don´t know how to make that one faster.

I did the same thing with the asus p8p67 and the i2600k, i have a lot of head room for performance, but I leave it for my pmdg jets to feast on. I run on bare default scenery and no ai. Runs great anywhere, even in the big apple. I've opted for a airliner simulator instead of a airport one... fs9 was good at doing both though..

I too have Aerosoft Schiphol. Don't know what AI you are using, but i use UT2 and dropping my traffic to around 35% along with just a little bit more to the left with my Autogen, i've got myself to 30FPS at that airport. Nice airport addon by the way. Regards,

What do you guys think is a safe tempature? I'm running an i7 860 4GHz at about 50-55C in FSX. Is that safe?

Thast wouldn´t be no probs at all! Really good in fact.But check also your GPU temp and d/l a program for free, so you could rise the Gpu fan earlier, when reaching a certain temp. / Leffe

Sounds pretty good to me. My cpu is different to yours so i'm not sure what your max is supposed to be but i would say it's a lot higher than 55C.

Ok nice to hear that! And yes I'm already running nVidia Inspector and manually set the fan speed to 100% to keep my temps under 40CBut anyway, a lower CPU temp would always be nice, and idea how I can adjust my Scythe Mugen 2 fan speed? I set it 40C target in BIOS, but it isn't spinning really fast at all.

Higher than 55C? My CPU or yours?

You are all fine there if the GPU isn´t more than 40C.....that´s very good!You don´t have to do anything about it then./ Leffe

My i7950 @4.4 (1.44vcore) with H70 and twin fans ran at 75 degrees when under load and i wasnt worried in the slightest, my GTX570 running at 900Mhz also hits 75 to 80 degrees, but this is nothing to worry about either!

Ha ha...I also see now you have the "BIG BEN" cooler, A. Vandervelde.....so why are you worried? / Leffe

Sorry if i confused you. What i was trying to say was that temps of 50-55C when refering to my cpu are good, as my TMAX is 98c and the rule of thumb for my cpu seems to be that if you are running FSX under 70C, you should be fine (mine runs at 50-52c in FSX). What i was trying to say about your temps with respect to your cpu is, that i'm not sure of the max temps on your cpu, but am sure it is way above 55c, so your temps sound fine to me.

After playing FSX for a few minutes and then immediately opening FSX showed that my CPU temp is about 57-60C.What I'm worried about is that the heat is gonna destroy my pc within a year or so.And when playing FSX, the CPU is not under 100% load. Under 100% load (I ran a test) the temps are about 80-85C, that's something to worry about... But luckily FSX doesn't use 100% of the CPU (I think).

You sound a lot like me. I get very nervous about temps too. When you read some of the threads in the various forums here, your temps look cool. I have to say though that still if you are below that 70c you are probably ok, but like i said, i am not 100% familier with your cpu.Some people would say to me, why are you only at 4.4Ghz on a 2600k? Because thats 'my' comfort zone.

57-60 is fine. Shouldn't be any major degradation at all. You can knock ten degrees off that temperature if you disable hyper threading. If you test with the Intel Burn Test [Linpack] it's great for stress testing, to check for stability, but not necessarily for temperature. It doesn't generate a realistic temperature you would be likely to see in everyday use. Prime is better for that. I presume you are monitoring temps with Real temp? 80-85 is the upper limit, so as long as you aren't seeing that temperature in everyday use, you are within the safe limits. Beyond that temp, continually and degradation becomes an consideration, and above, you star to enter the throttling zone. I'd definitely disable HT though, and save that 10 degrees. Martin Wilby

Just adding more experience to the fire for overclocking. I have an i7-920 which is a little out dated now, but not bad. I had originally clocked to 3.50 GHz, but hadn't gone further. I was babying the CPU a little since I didn't want to burn it out. With the new i7's out, I still don't want to burn out my CPU, but there are good upgrade options if I do now. So I went ahead and raised the clock from 3.50 to 3.78 GHz. A reasonable change, but not necessarily huge. I then loaded up the NGX at FSDT's PHNL (+UT2 at 90%, REX, GEX, etc). This was my previous hard hitter for some reason and previously I would get 11-13 fps at the gate (it was an oddity, most places I got 18-19 fps with heavy ground add ons). Now I get 23-24 fps at PHNL and will be testing other situations to see what happened there. Eric Szczesniak

Don't forget to set AffinityMask to 14 in FSX.cfg. You'll see a marked perfomance increase when you do.

Hello if overclocking is so good why dont the makers do it for us...? mine is smooth 30-33 fps in the vc at a orbx airport, what would i gain?thanksjames2011-9-9_18-24-39-446.jpg

Hello if overclocking is so good why don't the makers do it for us...?
Because the manufacturer, has to take into consideration that all systems are different. The manufacturer of the chip, hasn't a clue if you are using the rubbish stock cooler, or a fancy water cooling loop. The manufacturer of the chip, also hasn't a clue if you have a high airflow case, or have everything jammed into a HTPC case. The manufacturer isn't going to sell you a super overclocked chip that generates tons of heat, becuse the majority of cooling systems out there aren't built for it. There's also the issue of chip variability. CPU's are speed binned. basically the slower chips are placed in one bin, and the faster and thermally efficient chips in another. Thats how the manufacturer determines whether the chip should be a faster or slower variant of the architecture. Therefore, the manufcaturer, in a way, is selling you an overclocked CPU when he sells you a more expensive variant of the architecture. But of course, it won't have the frequncy set as high as an overcloker would set, and the chip itself would be good for higher frequnces with minmal volatge increse. Martin Wilby

my goal is to keep the temp below 75°C with 30°C ambient tempbut I would never go above 80°C for CPU temp ... if you keep it below your cpu will live a long life ...keeping the temp at or below 50°C with 100% load is just a waste of performance
