i5 6400 oc - Can they all oc?
I'm curious about purchasing an i5 6400 and OC it!
I came across some used ones on eBay and I'm tempted to buy one of these.
My concern is whether all of them are suitable for OC.
I understand that the motherboard and BIOS version matter, but since you have a capable motherboard, would any i5 6400 be able to achieve full overclocking?
It might not be an exact match to your query, but I can assist a little.
Currently, I'm also in Germany and from a developing country, so my suggestions could still be useful.
I found that you can find decent offers by searching for 4670k or 4690k on Auktions on eBay. You might be able to get a 4670k for around €100-120 if you try a few auctions and stay patient. This could help you obtain an overclocked chip, and the performance gap between Haswell and Skylake is minimal, so you might even achieve better results (Haswell chips usually reach 4.4 or 4.5GHz) without needing extreme overclocking techniques.
I highly suggest checking out used Haswell overclockable chips, especially when placing bids.
Intel did not originally plan these CPUs to be overclockable, but it is feasible if you use the correct motherboard and BIOS version. According to my understanding, the i5 6500 performs better in overclocking compared to the i5 6400. Also, keep in mind that accurate CPU temperature readings may not be reliable, and there is a risk of damaging your CPU.
The goal here is simply to cut costs. I can purchase a used i5 6400 for 120 euros, while a new one would be 170 euros. The rest—like the motherboard and DDR4 RAM—seems like a good deal. A new i5 6600k is about 240 euros.
I’ve seen various guides and most of them report impressive outcomes, though they often highlight only the positive cases.
I know Intel doesn’t want us to use these CPUs because they lose money, so they encourage people to opt for the newer models with BIOS disabled and microcode updates (what does that even mean?).
I’m trying to find a better value since I’m always on a budget. If you’re looking for something straightforward without needing detailed examples or personal stories, please don’t reply—we’re wasting time if we do.

What country are you from and what is your overall budget for CPU, motherboard, and RAM?
Please don’t be rude—I don’t think I’d help someone who doesn’t want to listen or understand. You can either let them correct you or ignore it and make a decision based on your own assumptions.
I’m just trying to guide you toward the best financial choice. Don’t blame me if you disagree. I explained why overclocking non-K processors isn’t wise, so please re-read that.
Additionally, regarding your previous comment, Intel does not merely sell chips as non-K and K; they are seen as misleading tactics that take money from consumers. The K versions of CPUs offer superior voltage management, enabling them to operate at higher speeds and voltages with enhanced stability. Non-K chips, on the other hand, are built to function within specific voltage limits and rated speeds to maintain reliability and performance. It's important to recognize that overclocking isn't suitable for everyone, and raising prices—even for those who don’t need it—would be a misstep for Intel, as it could reduce sales among average buyers who lack the expertise to overclock effectively.
6400's have shown the ability to reach 4ghz+ in certain cases. As mentioned before, these outcomes are influenced by the specific chip and board used. These findings aren't assured, but I believe a 3.2ghz would be quite straightforward and still provide a solid improvement over the 6500. Only two models are confirmed to have overclocking boards with locked chips: Fatal1ty B150 Gaming K4/Hyper and Fatal1ty H170 Performance/Hyper. These feature a distinct clock for the CPU, ensuring stability elsewhere in the system. While I generally follow Chugalug's recommendations, I feel the 6400 was intentionally limited to a lower clock speed to bridge the gap between the i3 6100 and i5 6500 for professional or general purposes. It’s likely just a standard 6500 that has been capped at a reduced frequency.
Another option for these locked processors is the Asrock Hyper series motherboards. They employ an onboard clock generator instead of relying on BIOS tricks to enable BCLK overclocking. Nonetheless, my feeling suggests that the 6400 models generally don't perform as well in overclocking compared to the 6500/6600/6600K simply because they are placed lower in the range. Despite this, many users still achieve notable overclocks with these CPUs, making them a good value if the cost is reasonable and you're satisfied with speeds around 4.4 or 4.5.
