Hi Guys,
So, as the post title states, I'm looking to overclock my AMD Piledriver FX-8350.
PC Specs:
CPU: AMD Piledriver FX-8350
Mobo: ASRock 990FX Extreme3 990FX
RAM: Corsair Vengeance 16GB DDR3 PC3-12800C9 1600MHz
Heatsink: Noctua NH-D14
GPU: ATI Radeon HD 5870
Case: Zalman Z11 Plus
I've heard the motherboard isn't the easiest to overclock, but I'm guessing most of the settings are pretty much the same.
I've had very little experience in the past with overclocking but I've read a few "starter" guides on the forums.
Ok, so after reading a few guides I've decided to give it a slow steady bash.
Start CPU Voltage > 1.3375v
Start CPU Multip > x20.0 4000Mhz
Increase 1 (11:47-11:57) - Failed after 10 minutes
1.3500v
x20.5 4100Mhz
Increase 2 (12:02-12:35) - Passed
1.3625v
x20.5 4100Mhz
Increase 3 (12:40 - 12:41) - Failed pretty much straight away.
1.3625v
x21.0 4200Mhz
Increase 4 (12:45 - 12:48) - Failed
1.3750v
x21.0 4200Mhz
As you can see, it seems to be failing at pretty low increases, not exactly sure why?
This is the error I'm seeing in Prime95:
"ERROR: ILLEGAL SUMOUT
Possible hardware failure, consult readme.txt file, restarting test."
I've not touched my NB Multiplier as I don't really know much about this. Although what I have read it's more of a tweaker once you've found a stable overclock...... Not sure how right I am there mind...
So right now, I've got a "35 minute" Prime95 run at 4.1Ghz. I find it hard to believe I can't go higher than that... I could start increasing my voltages but I'm not too sure how high I can go without causing damage? I'm basing my questions around this review:
http://www.tomshardware.com/reviews/fx-8350-vishera-review,3328-2.html
Where TomsHardware got 4.8Ghz from 1.375 V CPU voltage and a 1.175 V northbridge voltage. I havent been to get anywhere near that, as you can see.
Thanks guys.
P.S. This is all a bit new to me (Overclocking), so please be nice ;-)
