increase core clock and memory clock of GPU individually?

[vikyy17]

in the sites i researched about overclocking GPU, first you try to reach a stable core clock by increasing it by 10mhz or so following each benchmark test. and once you figure out maximum core clock we can go with increasing memory clock and follow the same steps. but in some other videos i watched, people first find out the their max stable core clock, reset, then figure out max stable memory clock separately. and finally they set both to the respective values they got. which method should i choose for proper overclocking?

Use MSI Afterburner as the main Overclocking program.
Overclocking tips :
- don't modify the core voltage (for begginers).
- don't touch the power limit (for begginers).
- add 25 MHz bumps on the Core Clock, after every bump run Unigine Valley Benchmark or OCCT for 30 minutes. (if you're getting artifacts, black screens , blue screens, 85+ degrees - LOWER YOUR FREQUENCY , until your GPU it's stable)
- add 25-50 MHz bumps on the Memory clock

Watch your temperatures with HWiNFO : http://www.hwinfo.com/download.php - when you're reaching 85+ you should stop Overclocking.

Increase GPU core clock and memory clock at the same time.

You post this same info anytime someone asks about GPU overclocking, its wrong.

The FIRST THING you should do is bump the power limit up. You are asking the card to draw more power by increasing the clock and eventually voltages. I don't know if you've ever overclocked a GPU but without modifying the power limit you won't get very far. Also 30 minutes of testing is excessive, your GPU will heat up and crap out within 5 minutes if there is a problem.

This is a good starting point for GPU overclocking:

Yeah it's the same..... I keep updating it , to be a great guide for begginers atleast.
I don't know what's wrong with it seriously. I usually don't recommend for begginers to increase the power limit.
Also you don't increase power limit from the start. You increase the Power limit when you see that the actual usage of the core has peaks over 100 %.

Please explain what's so wrong about it, from what I see it's similar to the one you posted here.
This was updated from the feedback I got from other , more experienced than you , users.
You don't need to run it from 30 minutes in case of instability , because you're watching your temps in the mean time and other glitches.

Whats wrong about it is the first step should be increasing the power limit, so excluding it for "beginners" is counterintuitive. Someone who takes your advice is barely gonna get 50 more mhz out of their card before it starts having issues, and then have to come back and search the answer again. By maxing out the power limit they can squeeze the most out of their card immediately, then if you want you can back it down, but there is no need to, its just a limiter. The card will draw the power it needs when it needs it, if it doesn't need the extra 20% of power it won't take it.

There are plenty of good guides out there such as the ones I posted. Better to just start on the right foot than to try it with 1 hand tied behind your back to avoid complexity, for people who get frustrated quickly its an easy recipe to get there.
