overclocking i5-4690k on ASUS B85M-G
overclocking i5-4690k on ASUS B85M-G
The prices I receive vary greatly, but I found a cheaper i5-4690k than the non-K version. I’m considering buying the K model now, though I won’t overclock it. It’s worth it if it meets my needs, but I don’t want to invest in something I can’t use. I read online that some users successfully overclocked 4th gen i5 and i7 processors on an ASUS B85M-G, so I’m seeking advice from the community.
Supermanu15 thanks for the update. I'm using an i5-4460 from work, so I'll return it right away. I'm only borrowing it to test, which is why I'm opting for the i5-4690 K or non-K. The 4460 is a Haswell Refresh CPU, so it should be okay. But checking the CPU support list shows the 4460 needs BIOS 0904 or newer, while the 4690K requires version 2001 or later. You might want to update the BIOS before you use the 4460, just in case.
I don't believe it's feasible to change the content of that board, but even if someone managed to do so, it would add a lot of extra stress to the basic power delivery system on the motherboard. That wouldn't be wise, regardless.
Still, opting for a "K" CPU could be beneficial since it tends to be more affordable. You won't be able to push it overclocked, but it should still function properly, and the lower cost is a plus.
The only thing to keep in mind is that if you're purchasing used, "K" series CPUs might have undergone extensive overclocking throughout their lifespan... it's hard to say for sure. CPUs usually don't fail or die just because they've been overclocked, but if the chip has been running under high voltage for a long time, the risk increases. That could explain why non-K models are often cheaper.
Make sure the motherboard runs the latest BIOS. It was released before the Haswell Refresh CPUs (such as the 4690K you're thinking about). If it's an original or second-hand unit, it might need a BIOS update to boot properly with a 4690K. The catch is that upgrading the BIOS will require a functional CPU, which could leave you stuck needing a budget-friendly, old, and compatible CPU just to make the change.

You should aim for BIOS version 2001 or newer for the 4690K.

Still, opting for a "K" CPU could be beneficial since it's generally more affordable. You won't be able to push it beyond its limits, but it will still function, and if it's cheaper then that's fine.
The only thing to keep in mind is that if you're purchasing used, the "K" series CPUs might have been heavily modified over time... you really can't be sure. CPUs usually don't fail or die just because they've been overclocked, but if one has spent a lot of time under high voltage, the risk increases. That's probably why non-K models tend to be cheaper.
Also, ensure the motherboard runs the latest BIOS. It was released before the Haswell Refresh CPUs (such as the 4690K you're thinking about) were introduced. If it's an original or second-hand unit, it might need a fresh BIOS update to boot properly with a 4690K. The catch is that upgrading the BIOS will require a working CPU, which could leave you stuck needing a cheap, old, and compatible CPU just to make the change.

You should aim for BIOS version 2001 or newer for the 4690K.
Thanks! But I'm pretty sure this is still accurate since I'm currently using an i5-4460 at work to get things running, and I'll return it right away as I'm just testing it. That's why I'm choosing the i5-4690 K or non-K model.

Thanks! But I am pretty sure this is updated as I am using an i5-4460 from work to get this up and running, I will be returning it immediately as I am just borrowing it to check, which is why I am buying the i5-4690 K or non-K
The 4460 was a Haswell Refresh CPU so you're probably fine.
However, if you look at the CPU support list I linked above, you'll see that the 4460 will run on BIOS 0904 or later, while the 4690K requires version 2001 or later. So you should absolutely take the opportunity to update to the latest BIOS while you still have that 4460. You'd be unlucky, but there's a chance it's sitting on the a BIOS version which supports the 4460, but not the 4690K, which would be very sad to discover once the 4460 has been returned.
Rhysiam shared the update details, mentioning the use of an i5-4460 from work. He plans to return it soon since he’s only borrowing it for testing. He’s considering purchasing the i5-4690 K or non-K instead. The 4460 is a Haswell Refresh CPU, so it should be okay. However, checking the CPU support list shows the 4460 needs BIOS 0904 or newer, while the 4690K requires BIOS 2001 or newer. He suggests updating to the latest BIOS before returning the 4460, as there might be a BIOS version that supports it but not the 4690K. He also referenced a previous post about the Haswell Refresh and linked a relevant article.

Rhysiam shared the update details, mentioning they're using an i5-4460 and plan to return it soon for testing. They're considering upgrading to the i5-4690 K or non-K due to compatibility concerns. The 4460 supports BIOS 0904+, while the 4690K needs BIOS 2001+. Checking their BIOS version, they confirmed it's compatible with the 4460 but not the 4690K. They're considering an update before returning.
Rhysiam checked and confirmed his BIOS version is 2501, which means everything should be fine.
Adaptive mode is something you can find in different explanations online; it wasn’t listed in his BIOS but was mentioned in some YouTube videos. He thinks it might be related to the CPU only, and since his processor isn’t unlocked, he might encounter it when using a different chip like the 4690K.
