Here is a common, casual rewrite of your question:
Hi, after using an i7-4770K for a long time, I'm finally deciding to speed it up a bit to make my PC last longer and use the 'K' badge properly. From what I know, turning off Turbo Boost and setting the clock to 4.0GHz is usually okay. I have an ASUS Maximus Hero VII Motherboard and a CoolerMaster V8 GTS cooler. Could someone tell me if they've done this before? I want to know which voltage to pick and which power-saving settings in the BIOS to turn off so I don't get stuck. Thanks so much!
You post this a lot lately. They made two different coolers, the first one being older and the second one newer with better cooling about six degrees warmer. Not sure if they put in more heat pipes or better fans. What are you trying to game on that PC? If so set the multiplier to 44 and voltage to 1.22 Then run OCCT if your temps are 80C or lower then fine for gaming. If your OC fails at that voltage then go to 1.24 and run OCCT again...
My CPU was only running at a low boost speed of 8 (800Hz), but when I started loading Unigine 4 in windowed mode with coretemp and CPU-Z open next to it, the clock jumped up to 3.9GHz. The voltage stayed around 1.112V while I ran it for ten minutes, and the hottest core reached 65 degrees Celsius. Maybe I should try starting at 1.2V with a 4.2GHz speed first, then run Prime95 later on.
Do you know if the Coolermaster MA410M could lower those heat numbers down to something closer to 90? I'm thinking about swapping out my GTS v8 for it.
The CM V8 GTS feels like a big, powerful cooler. You might want to try re-pasting it before you go buy something new. The V8 GTS should work better than the MA410M. It seems your voltages are right in the middle.
You seem to post this often. They made two different coolers; the first one was old, and the new one cools about six degrees better. Maybe they added more heat pipes or better fans? What are you using your PC for? If it's gaming, set the multiplier to 44 and voltage to 1.22. Then run OCCT. If temps stay at 80C or lower, that works fine for gaming. If the overclock fails there, try lowering voltage to 1.24 and run OCCT again. Nothing needs changing in OCCT; just click the green button! Intel never officially tells us their exact safe max temp for 24/7 use because they put a limit on how hot CPUs can get before they slow down at 100C. But personally, I'd avoid going over 85°C. If OCCT hits an alert about 85°C, the test stops just in time to save your CPU. It's meant for stress testing, so if you're gaming, those temps might actually be higher during real play.
Thanks for sharing those details. After testing coolers for about 4 days, I ended up with the same feeling as before. If I spend the effort of repasting (the case is huge and might need me to take out my mobo), I was looking at putting an i7-4790K in it. This is the top CPU my Asus Maximus Hero VII supports. Is it worth it? I could sell my 4770K as-is, since I haven't started tweaking it yet. A used 4790K costs around $350 AUD ($244 USD), but a used 4770K might fetch about $150 AUD, which seems like a good deal to switch while repasting. Another question: if someone knows what GPU is the bottleneck for these CPUs (4770K/4790K), that would be helpful. I enjoy gaming but mostly do word and excel work, plus some video editing with ACDSee Video Studio. My split is about 40% work, 40% gaming, and 20% editing. My monitor is a 144Hz/1080p screen, so I want to get max slider at 120 FPS in first-person games like Thief, Batman, Tomb Raider, or Splinter Cell when things are going well. I am trying to tweak my system to save money for about another year before building everything new. I am currently setting up a GTX780-DC2OC with SLI (I already own two of them and haven't tried SLI until now), but I'm also considering upgrading to the GTX1660 Super (MSI Gaming with LEDs) or just saving for the best card these CPUs support, or even getting higher so I can move my graphics card into a new build later.
Those two chips, the 4770K and the 4790K, are essentially the same thing. The only change is that the new version has slightly better cooling so they don't run too hot.
