New to OC need help with 990X

[bladfury]

Hey guys, this is my setup

Intel core I7 Extreme 990X
12 GB ddr 3 2663 MHZ ram
MSI Big bang motherboard
MSI geforce 580 GTX lightning graphics

I am running on air cooling, and was wondering if i could get some help on overclocking my CPU maybe to about the 3.8 or 4GHZ mark, if anybody could help me out with the correct voltages and timings etc, as i am pretty new to all this

What kind of air cooling? It makes a difference on what you will acheive.

[bladfury]

It looks almost identical to this one, with ofcourse a fan on top that allows for RPM to be turned up with a switch on the side.

This might help. Im sure one of the otherr members will be around to assisit too. Overclock3D :: Review :: Intel Core i7 990X Hexcore 1366 :: Test Setup and Overclocking

You may not be able to reach the max OC because of your cooler. I am not sure how good it is since I dont know what cooler that is. Reminds me of a tuniq tower 120 without the spiky fins. You may want to look into a better cooling solution like a AIO, Customer water or a Big air cooler from Phanteks or Nuctua.

Thanks for the link, i want to try get mine to about 4 GHZ, but i am not sure if those timings and voltages would be the correct ones for that?

Go slow. Up the BCLK slowly until you reach a point of it being unstable. Then back off. Run a cpu bench mark after each bump in BCLK. After you reach a stable BCLK. Write it down for just in case you need to clear bios because it wont post. Then try to move up multiplier a little. You made need to up vcore voltage a little to keep it stable.

You should be able to hit 4.0 without having any issues with just moving the BCLK up. Keep an eye on your temps. Again I don't know how good your cooling is so you need to watch it. Get Core Temp from here.... Core Temp

The key to all this is to read everything you can and take your time. Dont hope in a try some settings you saw someone else post. Every Cpu is different. Some can go high some cant. Good luck.

You won't be able to keep that chip running at 4Ghz on air cooler. 990x has unlock multiplier, the easy way to OC this chip is to increasing the multiplier instead of Bclk.

Take a look at our 4Ghz club (link under my sig), this thread has enough information for you to get started, if you have any problem just post the question and tell us exactly every step you take, you can post in that thread if you like then we'll guide you through.

Don't know how good your cooler is but keep the cores temperature below 70°C.

Could you please fill out your system specs on your profile, thanks If you are really set on 4GHz, lowering your memory speed will make it easier to achieve along with disabling Hyperthreading. Doing this will decrease heat and voltage needed. What I did for my 920 may or may notwork for you; check what your core voltage is using CPU-Z, set that as your core voltage and increase it by .02V and try upping your Multiplier to get to 4GHz. If it does not post, increase voltage. If it does post, try lowering your core voltage step by step until it does not post. Once that happens, increase the core voltage by one increment, boot into Windows and run Prime95. If it crashes, go back and bump the voltage up by one and repeat this process until you have no crashes. Oh, and keep a close eye on temperatures!!

I've owned both the 990X and 980X and was able to hit 4.6GHz as well as 4.8GHz with the Noctua D14, if fact here's one of the CPU-Z screen shots showing 4.6GHz I'd have to search for the 4.8GHz validation

The 990X is unlocked, and runs cool, and is very easy to overclock, just use the mulitiplier, set it at 40 for 4GHz, and raise your v-core to 1.38v, and make sure you disable any power saving features. If you want to go higher than 4GHz, you have to make other changes in the bios.

Yea I have to agree I got my 980 (No X) to 4.5GHz in less than an hour and it was my first overclock, very nice chip

Where would i find the mulitplier? sorry for the noob question, literally my first time trying to overclock..
I have just ordered myself the Noctua D14 just to make sure i have decent cooling.

Hey Bladfury,welcome to PureOC!
The multiplier can be found in your bios, this is where you will increase your vcore as well. To get into your bios restart your comp and continually hit F12 or delete, it will say what to hit when your computer is restarting.
