FX-8350 Overclocking help!

post #1 of 86
Thread Starter 
Hey guys, I really need help with overclocking. I'm use to a 4 core processor, I had an Phenom II X4 840 at 4.2GHz with no issues, and was very stable. I've upgraded everything since then.
My rig specifications:
CPU: AMD FX-8350
Motherboard: Gigabyte GA-990FXA-UD5
Ram: G.Skill F3-12800CL10-8GBXL 2x8GB 1600MHz
GPU: Sapphire HD7870 2Gb GHz Edition

So on and so on. Now, I've been meaning to overclock it because 4.2GHz turbo boost wasn't good enough. I have a water cooling system as well and not a closed loop setup. Every time I try and overclock I constantly get blue screens while running prime 95 no matter how much I overclock it by. The only time it is stable is when it is at 4.2GHz. Here is my settings in the bios.
CPU Clock Ratio: x23 (4.6GHz)
CPU NB Freq.: Auto (2200MHz)
Core Performance Boost: Disabled
CPU Host Clock Control: Auto
PCIE Clock(MHz): Auto
HT Link Width: Auto
HT Link Freq.: Auto (2600MHz)
DRAM E.O.C.P: Disabled
Set Memory Clock: Auto
Memory Clock: x6.66 1333MHz (For some reason it has a error on post when I try and set it to default 1600MHz)

System Voltage Control: Manual.
CPU PLL Voltage Control: Normal 2.500V
DRAM Voltage Control: Normal 1.500V
DDR VTT Voltage Control: Normal 0.750V
NB Voltage Control: Normal 1.100V
HT Link Voltage Control: Normal 1.200V
NB/PCIe/PLL Voltage Control: Normal 1.800V
CPU NB VID Control: Normal
CPU Voltage Control: +0.125V (1.4750V
Normal CPU Vcore: 1.3500V

AMD C1E Support: Auto
AMD C6 Support: Enabled
AMD K8 Cool&Quiet control: Disabled
AMD APM Master Mode: Disabled
CPU Core Control: Auto
One Core Per Compute Unit: Disabled

So what exactly am I doing wrong? If it can't go past 4.2GHz then I have to be doing something wrong. Thank you for the help.

hello,
check if EEC is enabled in bios.

I've looked through the bios and I don't have that option.

Any other ideas? I really want to see how far it will go, and it will help loads with my rendering times etc.

whats your timings on memory? this could be reason u cant run 1600

other than that i cant see anything that sticks out. Prime can be crappy with some visheras. try running OCCT

Disable all of this:

AMD C1E Support: Auto
AMD C6 Support: Enabled
AMD K8 Cool&Quiet control: Disabled
AMD APM Master Mode: Disabled
CPU Core Control: Auto
One Core Per Compute Unit: Disabled

It will definitely help.
I am not a gigabyte owner so i cant really help too much but my C5F-Z has the same features.
i can push my 8150 to 4.4ghz with just multiplier.

I would recommend flashing the latest bios firmware to your mobo if you have not already. Here is the web page: http://www.gigabyte.us/products/product-page.aspx?pid=3891#bios. It may help with system stability.

My Bios is F10b. Also is this motherboard capable of the UEFI Bios?
I'm not too sure which one is ram timings but I think it's C9.
DRAM Frequency: 666.7MHz
FSB:DRAM: 3:10
CAS# Latency: 9.0 clocks
RAS# to CAS# Delay (tRCD) 9 clocks
RAS# Precharge (tRP)
Cycle Time (tRAS) 24 clocks
Bank Cycle Time (tRC) 33 clocks

The speed is suppose to be 1600MHz but it won't go that high because of a error in the clock ratio x ht link or something like that so it won't let me past post if I push it to 1600MHz.

I updated my bios to the latest which was f10b at the time, but I'm worried on doing it again because I can't remember last time how I exactly did it, and if I recall flashing the bios is dangerous if done incorrectly.

well as another mentioned disable c1e support it is a auto downvolting / downclocking feature a lot like amd cool n quiet for a second also disable c6 support this is a auto vdroop control feature built into cpu.

I want to point out don't use the auto vdroop controls built into cpu aka c6 support it causes instability use the motherboards version of vdroop control and adjust the needed voltage and multiplier manualy in bios not through software that is most unstable and buggy way of overclocking is with software now also make sure your bios is fully upto date another issue I found myself was memory needed a slight bump in voltage along with CPU/NB volts (cant remember exact amount it was originaly or after but a 0.10v bump from oem I believe is what it took ) to get everything stable also NB voltage itself needed a slight bump for me to 1.20v some require 1.25v.

I hope this helps the voltage bumps are to compensate for regular voltage droop on CPU/NB , NB , and ram volts when you overclock cpu more current is drawn away from other areas enough to cause a vdroop on other parts.
