I did quite a bit of research before building my new rig a week ago and the word around the net seems to be that the 4.6-4.7Ghz OC seems to be the safest and most stable OC. Unless you found the golden ticket that runs at 5Ghz. To be honest I haven't bothered trying to push it. I was too excited about the idea of running my CPU above 100 degrees 24/7. But just curious if anyone else has a similar set up to mine and is running much higher and stable. Looking to compare over clock set ups :cheers:
Huh? 100 degrees? Fahrenheit you are completely safe at 100 degrees, if you meant Celsius there would have to be something wrong somewhere! 100 C (212 F) is way, way too high for the CPU!
I meant celsius but was slightly exaggerating of course. Several reviews I read where they upped the voltage to around 1.45V to get around 4.8Ghz, the cpu temp increased to 85 degrees C. So I'm not too comfortable getting up that high. Even a cooler won't help much at those higher temps.
The point where you need a whole heap more voltage and noticeably higher temps for such a small increase it isn't worth it. You could tweak your RAM a bit, if it's the same as mine it can do 1T. Also you can set the refresh period (interval) to around 13000 give or take, which helps. I also run my bclk at 102, so the RAM is actually overclocked (2448 or something). Keep in mind I have an i5-3570K, I think the default bclk of your CPU is 133, so you coil use 2 percent on that, making it 135.6.
Exactly. What I found odd about the ram was it ran under clocked by default and had to manually up it to run at stock 2400mhz. You're suggesting I may be able to go more than that?
I can with mine, you should be able to. I did some quick googling just now, maybe your bclk is 100 still. Going to 102 should be fine and safe, 102 over 100 doesn't sound much, but it is 2 percent, and 4.7 GHz to 4.8 GHz on the CPU is around 2 percent! It also boosts the RAM, PCI-E etc 2 percent. Try tuning your other settings too, like the bclk strap etc.
You can, but you will get lower ram bandwidth (read/copy). Keep at 2400mhz, its golden middle. Maybe set 1T instead of auto (2T) As for your OC that's what most do usually 4.7ghz, only a few 4.8 - 4.9ghz., temps. and voltage becomes limit soon.. https://docs.google.com/a/overclock...d1OWo2a2ZlTkxjdWVtUmc&usp=sharing&output=html btw dont stress test in prime95, use Intel xtb or Asus Real Bench2 http://www.intel.com/support/processors/tools/xtu/sb/CS-033226.htm http://rog.asus.com/241042013/overclocking/rog-realbench-free-app-download-now/ , if it passes both benchmarks at reasonable temps then you can go higher.. Also what kind of voltage do you need for 4.6 or 4.7ghz? :nerd: For example here is my 3dmarks physics test 4770k @4.7ghz, cache 4.2ghz, ram 2400mhz cinebench15, best @ 4.7ghz was 964 & 188cb
4790k@4.7 1.28v. Runs 24/7 using a H100. Asus Z-97 Deluxe. Corsair 600t Case Temps are around 40c-70c. And it's very hot here this summer. (right now its 31c and i live in the northen Part)
You mean under normal operation right? if not, you must have the best 4790k. I can do 4.8 at 1.28 but my xspc 480 and a 240 xspc rad with a raystorm block keep it down jus under 80c at full load while performing Aida stress test. 28-30c idle and 50c under regular use( gaming and such)
I get around the same temps as he in normal scenario, same volts and freq. 4.7ghz @ 1.280v @ H90 cooler. But yeah this is mostly in gaming. Actually I never see it above 65C, only by loading up to ~ 68C sometimes in Bf4 or COD Ghosts, otherwise 40-60C. Only cinebench15 or fritz Cheesmark or 3dmark SkyDiver physics test heats it ~ 70-72C on core0, always the hottest. Something like x264 encoding is another story though.. The hottest so far I saw was 78-82C using openCL, but I was using adaptive voltage which made 1.36v jumps and this will heat extra, esp on old Haswell..
The jump from 4.7-4,8 brings temp up 20C. (becouse i have to bump voltage to 1.3 or so) Sweet spot is 4.7 And yes, when gaming bf4 i hit around 60-70
