Typical newbie post--but I'm not an idiot

post #1 of 9
Thread Starter 
Hi there,

First post and all, so assume I know nothing about the forum. I'm new to overclocking but I think I've done this right. I'd like to get the best out of my recent build and I've only ever really gone with the Asus "auto-tweaker" approach. Here's the details:

Mobo: ASUS SABERTOOTH 990FX R2.0 AM3+ AMD 990FX +
CPU: AMD FX-9370 Vishera 4.4GHz Socket AM3+
GPU: SAPPHIRE DUAL-X Radeon R9 280X 3GB
Cooling: CORSAIR Hydro Series H100i
RAM: Mushkin Enhanced Redline 16GB (2 x 8GB) DDR3 1866 (PC3 14900) 9-9-9-27
PSU: Rosewill LIGHTNING-1000 1000W

Here's why I want to overclock: I'm a game developer. Running the editor, making builds, baking lightmaps, rendering scenes from Maya or Vue, all of these things take a long time and could go faster if I got more clocks. I also have an SSD so I've reduced the bottleneck there. I think I have power and cooling covered. At stock frequency, the CPU sits at 38C under a moderate amount of load. Idle is more like high 20s low 30s. Anyway I know I have the room there. I'm not sure how to gauge how much "reserve power" my PSU has.

People writing reviews on newegg said they got 5GHZ+ out of the chip. So here's where the questions start:

I know that my goal is to change the base clock speed and mutliplier to get the CPU to go faster, and probably do something with the RAM and/or FSB frequency yadda yadda. What I'm really confused about is tweaking voltage and power settings and when that is appropriate.

I'm the type of person who likes to know the theory behind something when he tries to do it. I'm also happy to "shut up and listen" if somebody wants to just give me instructions on how to make this happen. Anyway, where do I start? I've tried some googling but haven't come across a guide for my specific hardware. Any advice?

Thanks in advance!

I generally start by lowering the cpu voltage in increments to find my lowest stable voltage then build from there. Each increment I will stress test it briefly, then slowly up the multiplier and voltage accordingly. Once you feel your near your highest stable overclock, run a long stress test and make sure you monitor the temps. I'm not too familair with the 9 series, i'm sure a real expert will be along soon thumb.gif

Use Prime95 and HWmonitor to keep an eye on temps.

So what exactly is "the voltage"? On this board, there are the following settings that seem to pertain to power:

I was going to copy them all down but here's the manual:

http://dlcdnet.asus.com/pub/ASUS/mb/SocketAM3+/SABERTOOTH_990FX_R2.0/E8042_SABERTOOTH_990FX_R2.pdf

You're looking for pages 79 -86

CPU Load-Line Calibration
CPU/NB Load Line Calibration
CPU Current Capability
CPU/NB Current Capability
CPU Power Phase Control
CPU Voltage Frequency
CPU Power Duty Control
CPU Power Response Control
CPU/NB Power Response Control
CPU Power Thermal Control

Basically exactly the same repeated for DRAM....

Then what I think it might be:

CPU & NB Voltage (this one?)
CPU VDDA Voltage
DRAM VOltage
NB Voltage
NB HT Voltage
NB 1.8V Voltage
SB Voltage
VDD PCIE
VDDR

Also, am I just modifying the multiplier? Not the bus frequency?
Should I bother touching my RAM? Should I leave it in full auto or the profile that shows up tuned for it specifically (the timing and data rate)
Another good thing to get out in the open--What are some common pitfalls that can do permanent damage to my components (other than overheating or stupidly high voltages or something)? What are the normal ranges for these things? IIRC most CPUs will clock down or shut off before burning themselves out but will do so around 90C.

I would only tweak voltages and multiplier, after that you can tweak the fsb and so forth.

People writing reviews on NE are also full of horse pucky. Many people "embellish" there stories a bit, 4.7 becomes 5.0. Add a grain of salt to all you read about OC'ing. It shouldn't take long for you to tell who is knowledgeable and who is bs'ing.

The first thing I do is run the system at optimized defaults for a few weeks, running and recording as many bench tests as I can. Learning how this particular pile of parts works together. Then I start the OC. Several very good guides available, pick one you are comfortable with.

I think an 600mhz bump on the 8320 and 8350 is reasonable for a majority with good cooling, not 100% on the 9 series but I'd imagine 4.8 should be somewhat achievable.

So I'm not sure that I got an answer on what "the voltage" means. Is it just the one voltage?

For me, would that be CPU & NB voltage?

CPU & NB would be where I would start, then again I haven't overclocked an AMD chip since my Phenom II.

Here are some definitions for you:
