Overclockers to the Rescue?

CrabCrust · 27 Aug 2018 at 09:15

After posting in the Upgrade thread and concluding that it might not be worth doing it yet it was recommended that I consider Overclocking.

My problem is that I have zero idea of what I need to do or anything like it.

I have the following -

- 16gb (4x4) Corsair Vengeance (https://www.corsair.com/uk/en/Categ...l-Channel-DDR3-Memory-Kit/p/CMZ8GX3M2A1600C9R)

- i7 2600k
- Gigabye GA-Z68XP-UD3
- Coolmaster 212 Evo

I don’t want my machine to make me breakfast in the morning but after running a benchmark on UserBenchmarks it says my spec is nearly 50% down on what others have of m same spec.

So is anyone willing to give me a little talk through of what I could do to give my machine a little boost?

would be a good starting point, although I'm sure a few others will be able to post more details regarding what voltages and speeds you are likely to expect

Much appreciated! Always been scared to do something like this but feel I’m in safe hands. I’ll read that tonight and maybe in the meantime some others are happy to throw tips and suggestions

You might want to try and find a calculator to work out what power consumption you'd be creating, the evo is rated for 150W, and that's from the manufacturer, so probably best case scenario. Any overclock you put on will need to not exceed that.

That CPU San easy do 4.6ghz. I would just Google a overclocking guide and follow it

Is it specific mainly to my motherboard or CPU?

Any ideas where I can find this calculator? And do I need much knowledge on what settings to enter? Again I'm completely useless with this and wouldn't know where to start.

I believe you can just use a half decent PSU calculator, a lot have a small section for CPU overclocks. I don't think I can link one here. But basically you plug in your CPU type, then the new speeds and voltages. You need to take into account the baseline wattage also.

I believe a 4.6ghz overclock at about 1.34V (that seems to be what the guide was suggesting, potentially higher voltage), is about 150W, which is going to be right on the edge of your coolers capability, if not exceeding. A 4.4ghz overclock looks to be within range.

However, that is assuming 100% usage, which you probably wouldn't be hitting, at 90%, 4.6ghz just comes back into range I guess.

So in the end, it's just a case of testing it. You will need to be sure that your airflow is good though, since if your fans are drawing in fresh air, hot air is just going to be circulated and you'll soon be hitting issues.

That motherboard looks like quite basic mobo with average VRM, so you don't want to go for heavier overvolting.
Power consumption rises to square of voltage increase... at same clock speed.
So besides CPU temperature VRM starts to get stressed.

Though good CPU cooler would make overclocking easier, because lower temperature CPU consumes little less power for same clocks.
