Overclocking stability w/ FX-8150 @ 4.5ghz. Almost there! Need advice!

post #1 of 3
Thread Starter 
Before I begin with my listing of information, let me be clear of some things. I am planning on upgrading to an i7-4770k later on (could be a month or two though). At the moment, I'm making the move to Nvidia 2D Surround so I've bought one GTX 780 Classified and getting another shortly. I was worried that I would be uber bottlenecked when I get the second one so I wanted to overclock this CPU for the first time to make the most out of it while I play BF4 and Titanfall among other games until I change to the other team. I have absolutely no prior overclocking experience with processors but a lot with GPUs. So taking what information I could soak from these forums and others, I started.

My goal is to run stable at 4.5ghz. No more and (hopefully) no less. I mentioned that I am using an AMD FX-8150 but it's the one that came with the stock liquid cooler that I believe Asetek developed for AMD. I'm not sure how great of a cooler it is in comparison to others but I believe it's somewhere near an H60-H80. I'm running Corsair Vengeance 32GB 1600mhz RAM and the Asus Crosshair V Formula motherboard, which I've taken the liberty of taking some Bios print screens to make things clear and easy.

First, here is a screenshot of Prime95 running for about 100 minutes while I was out.



As you can see, the 8th core shut down after 17 minutes. The other cores went onwards for about 100 minutes. This was with the Small FTT test.

My current bios settings are as follows.










I know a lot of people who ask for help tend not to have all of the necessary information (subjective from thread to thread) but I wanted to get all of this out the way to get the most effective answers.

While waiting for answers, I will dial the multiplier back and see what my results will be. I really want to stick with 4.5ghz though.

Thanks in advance to everyone! Very much appreciated

For me when going over about 225 fsb, I find having the HTT and NB speeds the same helps a bit in stability. Choose about 2500 or 2600. Also up the NB 1.8v a notch or two.

You also need to up the other NB and HTT voltages as expained here:

Also, what ram are you using ? It looks like you have it set way too low.

And what specific Asus motherboard ?

I posted those two bits of information in the original post. I know it can be hard to ride under all that text and pictures! lol

As for right now, I decided to re-go from scratch and managed to pull this



Definitely a huge improvement. However, when I tried to run it with 21.5 multiplier, it errored out after about 30 minutes. Because I'm using the free version of HWMonitor, I can't really tell if there was a voltage droop right at that very same time. So I'm thinking that I should try dialing back the multiplier just a hair (20.5) and raise the FSB a bit (still on stock voltage) and see if I can achieve it. As of the last stable test, my headroom was 2 degrees. So dialing it back just a hair should fix it. I could also probably drop my voltage a notch. At the moment, I've got my memory running at auto so CPU-Z says it's running at roughly 1400mhz. I think I'll leave it alone again as I raise the FSB a smidgen.
