I need some help to speed up my Intel processor, specifically an i7 4770K.
I have been trying to find the best settings for overclocking on my MSI Z97 Gaming 3 motherboard and my i7 4770K CPU for a while now. I feel like my current BIOS options are holding me back from getting the most speed out of my processor. I keep testing myself with Intel burn tests, then running AIDA64 stress tests, Prime95, Cinebench, and even delidding my CPU to see if that helps lower temperatures. My main problem is just the BIOS settings; I never really dug deep enough into them and still don't get everything working perfectly.
Here are all my PC specs: an i7 4770K, a Liquid Metal Pro NZXT Kraken X62 water cooler, an MSI Z97 Gaming 3 motherboard, Hyper Savage 16GB RAM running at 2400MHz, and lots of storage and power from Corsair and Kingston. My BIOS settings are these: CPU Ratio is set to All Core with a frequency of 45GHz in Fixed Mode, EIST is turned off, Intel Turbo Boost and Enhanced Turbo are both disabled, Legacy Tweaking is off, OC Genie Function Control is on but only by BIOS Options, Ring Ratio is set to 45GHz. The base clock for the CPU is 100MHz, PCIE PLL is Auto, Filter PLL is Enabled, DRAM Frequency Clock is Auto at 2400MHz, and Extreme Memory Profile (X.M.P) is on in Profile 1 with Memory Try it! enabled for CL11 Compatibility. I have DigitALL Power On, CPU Phase Control set to Normal, Vdroop Offset Control set to Mild (+37.5%), Over Voltage Protection at 600mV, Under Voltage Protection also at 600mV, Over Current Protection turned off, Switching Frequency at 740KHz, VRM Over Temperature Protection off but Shutdown enabled, Digital Compensation x1.2, Imon Overwrite Auto, Transient Boost Disabled, SVID Communication On, VCCIN Voltage set to 2.200, and CPU Core/Ring/GT Voltage Mode is Override while Core Voltage is 1.280, Ring Voltage is 1.350, SA/IOA/IOD Voltage Manual with specific values for each, DRAM Voltage Auto at 1.650, PCH 1.05 and 1.5 voltages both Auto. Hyper-threading is On with All Active Processor Cores selected. I have Hyper-Threading Enabled, CPUID Maximum Disabled, Execute Disable Bit Enabled, Virtualization Tech on, Adjacent Cache Line Prefetch On, AES Instructions On, Adaptive Thermal Monitor On, C-State Off (because it's long duration), Long Duration Power Limit 4096W for 128 hours, Short Duration also 4096W, Current Limit 1024A. The VR Iout Slope and Offset are both Auto, Internal VR OCP Protection is off but Internal VR Effeiciency Management is On, Internal VR Switching Frequency +6D, DMI Gen 2 Enabled, De-emphasis control -6dB, CFG Lock Enabled.
I also need to know what to set my PCI latency timer to since the default is 32. Should I change it to 32, 64, 96, 128, or keep it at 32? Is there anything in here that will make me more stable while overclocking? It feels weird because I can hit a core frequency of 4.5GHz but have to increase the Ring voltage instead of the Core voltage just to stay stable. Even when both are set to auto and suddenly it gets unstable. So why am I stuck at 4.6GHz core & ring since that's what I've been using? If you see anything in my BIOS that you think should be changed, let me know. Thanks for reading.
I'm getting the same kind of result. My 4770k runs at a steady 4.5Ghz, and nothing in the BIOS settings changes that or stops it from running hot. This is really annoying because with my Corsair H100x I'm only reaching temperatures around 60 degrees Celsius even under full load. I think this means for me and probably you too that I've hit a hard limit. Moving up just from 3.5 to 4.5 GHz while staying stable isn't easy, so maybe we just have to live with what it is at least. What were you hoping to achieve by trying to get higher? Anything over 4.7 GHz would be great!
I am getting the same result. My 4770k runs stably at 4.5Ghz, and nothing in the BIOS settings helps anything else which is really annoying because with my Corsair H100x I'm hitting full load temps around 60 degrees. I think for me and maybe you that it has hit its limit? Going from 3.5 base clock to 4.5 and still staying stable isn't a small deal so I guess we just have to accept it what it is? What were you trying to get anyway? 4.7+??
