Hello guys. I recently bought new parts for my pc. The ram i bought was a savage hyperx 3000mhz . BUT in the bios of the mobo it said. 'memory 2133mhz' so i overclocked it to 3000mhz which was the main speed of the ram. But i wonder what will happen if i overclock it to the max setting, it was 4xxx i dont rembmer exactly. I got another question tho , does making my system more performance biased killing my cpu gpu faster? I mean i set it to ASUS OPTIMAL on the bios and i did the same for the gpu too. I just want it to be slightly better. I know my english suck btw and i am a noob but hey, thats why you are here <3
Thanks
Pc specs
GPU: Amd radeon sapphire r9 380x nitro (factory oc)
CPU: Kaby lake i5 7600k
CPU COOLER: Cryorig h7
RAM: Savage hyperX 3000mhz (1 stick)
CASE: Thermaltake versa c22
PSU: Corsair 650rmx
And what do you think about my build btw? I can run almost everything on ultra.

I would run the ram at 1.2v 2400 speed and go from there.

If I paid a premium for DDR-3000 RAM, I would run it at its rated speed. After all if it don't work, then they gotta give you new set.

MOBO: Asus z270f Gaming
And it supports way higher speeds.

Memory Standard = DDR4 3866(OC)/ 3733(OC)/ 3600(OC)/ 3466(OC)/ 3400(OC)/ 3333(OC)/ 3300(OC)/ 3200(OC)/ 3000(OC)/ 2800(OC)/ 2666(OC)/ 2400(OC)/ 2133

Maximum Memory Supported = 64GB

Channel Supported = Dual Channel

However ...1 stick ? I can not understand how this oversight continues to be made to this day .... Dual Channel = 2 sticks. I'd return it and buy a matching pair.

Always good to post your prospective purchase BEFORE you buy.
I would have advised you to buy a 2 stick kit of ram to operate in faster dual channel mode.

That said, since you have a discrete graphics card, you are not losing much.

DDR4 ram will all run at 2133 so you can boot into the bios and select a higher xmp setting.
But, faster ram is not all that beneficial to real app performance.
Here is a report:

Once it all works, you are not going to get anything significant out of tweaking ram settings.

Without knowing your motherboard and oc level, I can't give you a good opinion.
If anything, the graphics card seems to be low powered compared to the cpu.

You gave a fair listing of relevant components but not the most important one ... the MoBo is ?

When you see RAM advertised at 3000, that is "overclocked" via Intel's XMP overclocking profile. The wat to do this properly in the BIOS is to select XMP and that's it, your done. You can see what speeds the RAM supports by downloading CPUz and running it... look at the SPD tab to see what speeds and timings are supported.

You also have to look at what speeds the BOOS supports .... can't do 3000 if the MoBo only supports 2666 ... later BIOS updates may allow for increased speeds. Above 3200 you are going to have to increase voltage. I don't know that you have seen all the "ooh ooh scary, scary posts that have propagated thru all forums claiming that anything over 1.2 volts will fry your PC, ... keep expecting to see that it will also make me sterile, cause my boss to fire me, blow my car's engine and make my kids drop outta college :)

But rest assured Intel is quite OK with your breaking the 1.2V barrier just as they were with DDR3 and 1.5v. All you gotta do is check the certified list of RM kits on Intel's web site ...every set over 3200 breaks 1.2v. According to Intel 1.35v is quite OK and advises not to go over 1.5v. Of course lower is ALWAYS better as it is with any component, but going higher won't bring on the apocalypse.

If interested in overclocking, I'd suggest visiting the RAM manufacturer's web site and looking around to see what other users have been able to accomplish and perhaps asking staff for recommendations on a starting point.

Your I5-7600K is overclockable with your parts.
How high is determined by your luck in getting a good chip.

As of 1/13/17
What percent of samples can get an overclock
at a vcore around 1.4v.
I5-7600K
5.1 28%
5.0 52%
4.9 72%

In overclocking skylake I found that higher ram speeds which need higher ram voltage seemed to inhibit my overclock.

I would run the ram at 1.2v 2400 speed and go from there.
