I'll leave the record breaking to the pros

Someone suggested I should be able to achieve a 4.5 GHz overclock with a 1.35V core and VCCIN set to 1.9V and that as long as my temps stay below 85C during the stress test I should be okay. Does that sound right? Also, maybe I missed it, but I can't find a VCCIN setting in the ASRock bios. Does it have a different name?

This was suggested to me because I was able to make it to the starting Windows screen with 4.5 at 1.3V. If I could boot past the bios with that setting then maybe it was possible to make it all the way into Windows with a stable overclock.

As you can see from my last post I try to stick to 1.3 or lower for every day use while pushing up to 1.45 for hardcore benchmarking. I wouldn't risk going any higher than 1.45 for stability at higher clocks, I have pushed my G3258 all the way up to 1.7v when I was trying for a 5ghz validation but that was with my PC on the balcony with the CPU fans running at full in -14c weather. Even then I hit 90c within seconds of booting windows and then got a BSOD. If you are looking to break records with OCing then you can take a few risks but if you just want a good stable OC then I would stick to about 1.35 on the high end. I currently hold the number 1 spot for a G3258 and a GTX 960 the Futuremark Firestrike rankings so my extreme seeming voltages were necessary to compete with other heavily overclocked systems. I would never run my PC at 1.45v 24 hours a day Wink

Okay. There's so many setting I thought maybe something was set to auto that needed to be disabled to reach a higher speed. I'm using the stock cooler right now so maybe I should look into an aftermarket cooler. I see you were using voltages upwards of 1.45. What's the most I should attempt? Everything I've read said to stay near 1.30 and that 1.35 is too much. But there seems to be a lot of conflicting info when it comes to overclocking. As a newbie it makes my head spin.

Welcome to the forums.

I have a G3258 clocked to 4.2ghz @1,28v. When I first purchased the CPU I had it on a B85 Anniversary and was able to get 4.5ghz @1.43v but anything higher resulted in BSODs, I then put it into a Z97 Extreme 3 and was able to get 4.6ghz @1.45v stable but with better cooling. Now when I say I was able to get 4.X I mean stable with 10 passes of IBT (Intel Burn in Test). You really need aftermarket cooling to get decent numbers out of the G3258, especially more recently produced CPUs. I have noted a trend where early production CPUs tend to overclock better, the closer the production date to the initial release the better. With proper cooling, like a Hyper 212 evo you should be able to hit 4.4ghz at about 1.4-1.45v even on a relatively modest overclocker. I generally run mine at 4.2 purely because that is the maximum I can get whilst still running my CPU cooler on lower, quieter fan settings. The 400mhz extra isn't really noticeable in most situations so I only set it to 4.6 for benchmark runs.

So in short, I doubt your board is holding you back, my B85 Anniversary probably could have hit the same 4.6 @1.45v if I had been using the same cooling solution I have on the Z97 system, a Thermaltake Frio OCK vs an old Arctic Cooling Freezer 12.

I'm trying to manually overclock a G3258 on a Z97M Anniversary board. I'd like to at least hit 4.4 GHz. Right now I can't get things stable with 4.0 GHz at 1.28v. I had to crack the voltage up to 1.34v in order to get Windows to fully boot at 4.1 GHz. It's possible I have a chip that won't overclock well, but before I give up I want to make sure the motherboard isn't holding me back. There's a lot of settings in the OC menu on auto right now. What settings should I be adjusting or disabling to assure the best overclock?

Thanks.
