issues with overclocking using a 4790k
Hi, I’m new to this platform. My friend mentioned it’s quite professional, so I’ll go through my issue. I have a Core i7 4790K with a 4GHz boost to 4.4GHz, 16GB RAM, GSKills Trident X 2400MHz CL11, and my motherboard is an ASUS Maximus Hero Vi Z87 graphic card GTX 1080 OC edition ASUS Strix in Sli.
My problem began when I overclocked the 4790K to 4.8GHz. It worked well with Windows 10 Anniversary Edition, allowing me to run benchmark tests from CPU-Z, AIDA64, and XTMILLY. Games like Tomb Raider Crysis 3, Far Cry 4, etc., ran smoothly at that speed. However, the 4.8GHz version crashed frequently, showing blue screens. My friends who have experience told me that 4.8GHz wasn’t stable, so I lowered it to 4.7GHz. That made it stable for long periods.
After reading forums and articles about the Devil Canon 4790K, some suggested switching from Z87 to Z97 mainboard to improve overclock performance. I decided to try that and replaced my Maximus Hero Vi Z87 with a stable 4.7GHz model using an H115i Corsair at 62°C watercooling. I also upgraded to an ASUS Maximus Ranger Z97 board. When I checked the latest bio on the official ASUS site, I saw discussions about the MAXIMUS VII RANGER BIOS 0809.1 and compatibility notes.
I’m hoping this update will help me meet my expectations for a stable overclock. Please let me know if you’re aware of what I’m talking about. Thank you all for your help!
This situation seems quite odd, as one would anticipate similar results. However, it appears to challenge its own logic by expecting all CPUs to reach 5GHz, which makes sense since each motherboard will handle overclocking differently and require a particular voltage for the desired speed. This is my interpretation. You might want to try raising the voltage up to around 1.4V, as long as your cooling system is adequate; with the H115i model you should be safe? What maximum voltage have you used before? Also, it’s advised to reinstall Windows from a clean slate during hardware changes like switching motherboards, especially when moving from Z87 to Z97 chipsets. If this were you, I’d simply revert the boards and lower the clock speed back to what you had.
yea i have a screenshot but i’m struggling to share it here. on the z87 i was getting 4.8ghz with 1.360v temp at 61 degrees and a 17% performance boost. then i tried 4.9ghz at 1.456v with 68 degrees and a 19% gain, which was possible to test but unstable. i also downclocked to 4.7ghz at 1.285v for 15% gain and it worked well at 60 degrees. the corsair h115i kept stable. i’m really disappointed with the z97 vii ranger rog board from asus—it can’t handle even 4.5ghz, so i spent money on it thinking a 4.9 would be easy, but still i’m confused why it doesn’t work and what’s wrong. i’ve tried increasing voltage to 1.460v on the vii ranger, but even then the 4.5ghz overclock failed to load the os. this is definitely not what i expected.
Yeah I get it.
It seems like the CPU might work fine at those speeds, but maybe it just needs better communication with the board. You could try swapping out the other motherboard for a Z87 if you prefer.
The BIOS versions on the two boards are likely very different, which could also be a problem.
The issue is that I sold the Z87 to get the Z97, which is an ASUS Rog material—it's not the cheapest board on earth.
Yeah :/ It’s basically the top-end model of motherboards, and it really disappoints since it doesn’t meet your performance needs.
You could always return it as faulty because it didn’t live up to your expectations just to check if it was the motherboard, but I doubt it’ll help much. Just send it back stating it’s underperforming, that’s all you can do and hope for a better one that lets you overclock more.
well nevermind the asus company here tell me if the board work fine and only the overclock is not achieve its not their problem overclock is not cover by the warranty i am very upset looks like nothing i can do for that pff thanks anyway
