Hey guys ,,,,

So I was talking with a friend the other day about processors and OC'ing and among things that he said is that "to OC a cpu to extreme rates it needs to have a (good patch) ..!

So what is (processor's patch) ? and how can I know if it's good ?

Appreciate all of you guys ..
Thanks in advance :)

It's something of a "roulette" as far as that's concerned. My best advice would be to try for something like 5.0 if you have the cooling and board to do it. If you can get it stable there, then keep going until you experience too much heat, or it gets too hungry for voltage.

The only way that any type of patch can affect how far you can overclock is if that patch is a bios update that will give you some extra overclocking features. There are OS patches that are released sometimes to make better use of the CPU but the CPU itself is never actually patched in any scenario.It's likely that either you misunderstood him and he said that the CPU has to be from a good batch or he doesn't know what he is talking about.

Ok , is there a way to determine that a cpu "batch" is good ?

CPUs are "binned" according to the quality of the wafer...for example...the FX 8320 and FX 8350 are the same CPU with the exception of factory clock rating. The FX 8350 is "binned" higher, meaning the silicon wafer is of higher quality and tolerates higher clocks more easily.

This comes down to Quality Control by the manufacturer.

You can look at historical averages of the specific CPU in general, if the majority are able to achieve a fairly high overclock, then the QC is typically considered to be good. If, the majority achieves a relatively low overclock...(like 4th gen Intels)...the QC is typically considered to be bad, or the yields from the silicon process they use are low.

In general, because AMD uses Partially Depleted Silicon On Insulator wafers (PD-SOI) their wafers are typically of higher quality than Intel. So they run cooler and achieve higher clock speeds than Intel. Intel's process is more advanced using 3 gates instead of 2, but they use a much cheaper wafer (bulk, in fact)...so their CPUs tend to run hotter and often achieve lesser overclocks compared to AMD hardware.

This accounts for why AMD currently holds every record for overclocking CPUs that is currently tracked. It also accounts for why thermal envelopes on AMD CPUs cutoff at 62C while Intel CPUs will go as high as 90C.

Depending on the CPU you choose, "binning" of the chip has an impact on the overclock you can achieve, but the motherboard VRMs, cooling system in place, and stability of voltage to the core (vcore) are also important factors as well.

On a given motherboard you might achieve an overclock up to 4.4 GHz on a given CPU, on a higher end board designed for overclocking, you might achieve something like 4.9 GHz. So, there are a lot of variables, the quality of the wafer is definitely one of them though.

Great, originally I want to OC my CPU to extreme rates like 5.5 or 6GHz , of course that requires an 8+2 MB and a potent cooler (possibly liquid) but the main issue is that the "batch" might not be good, so what i'm asking is that there is somethig that you could "spot" that tells you it's a good quality or is it a " roulette " so to speak ?
