Hello and thank you for taking your time to look at this post.

First Let's get the specs out of the way.

Antec Twelve Hundred V3 Black Steel ATX Full Tower Unbeatable Gaming Case

Cooler Master Silent Pro M - 1000W Power Supply

AMD FX-8350 Vishera 4.0GHz (4.2GHz Turbo) Socket AM3+ 125W Eight-Core Desktop Processor

CORSAIR Dominator Platinum 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory

ASUS Crosshair V Formula-Z AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Gaming Motherboard

My question is. What can i OC my rig to without water cooling or extra fans?

My Case Has:

3 x 120mm blue LED front fan with front speed control
2 x 120mm blue LED rear fan
1 x 200mm top Big Boy 200&tradel blue LED fan

I leave the Side Panel Window off just for extra cooling.
(Air Conditioning is always on so my room always stays nice and cool)

I'd watched/read a few guides to try to learn myself, But each and every time my rig crashes when i aim above 4200.

Like i watched this Video below.

http://youtu.be/MckeAmnDeTk

I did a baby step and am currently running at

4113.61 MHz

which actually seems to be working.



As i look at CPU-Z though. the Core Speed jumps from 4113.61 MHz Multiplier x 20.0 to a Core Speed of 1439.76/1440 Multiplier x 7.0 back to 4113.61 MHz every few secs. Is that normal??

But what really stumps me is Voltage and RAM. like the more i bump up the Bus to OC, the RAM settings change as well (2133 disappears completely) and i dunno what to set the new values at.

Since i changed it to 4113, The ram changed as well.

As for voltage. I'm at a loss. Think i have it on auto at the moment.

Just wondering if anyone could toss me a Setup to try out That won't destroy my rig lol.

Any help would be appreciated.

Yeah, I agree. I would not go any further than 55° C on the core and about 60° C on the socket. Depending on what a good friend of mine said (hardcore overcklocking type of guy)...

dont use auto for voltage
do to the cpu tab on cpuz
run a program that maxes out the cpu and see what the voltage is
then input that instead of auto
should be more stable from there and keep bumping as need for every jump
make sure to stay under the temp limit atleast 10c away from max

yes your voltage is 1.284
you bump it when unstable
usually you got about 0.010 to keep it from going over and frying the cpu
so lets say your at 1.284 which you are you would go to 1.294 and from there if not stable you will go to 1.304
get what im saying?

Little tip: AMD FX offers open multipliers
Your RAM changes as well your NB frequency and your HT link speed because you are overcklocking your FSB.
This things depend all on the FSB.

Try not to OC the FSB, try to raise your CPU frequency by increasing your CPU multiplier.

First of all, set everything to auto and check your settings (voltage, frequencies, multpliers) on CPU-Z, these are the settings you start with in BIOS.
Then ONLY increase the multiplier, and test for temps an stability in prime. When everything is fine, increase the multiplier again.
Do this until you have save temps and on or more of your cores fail, then try to slightly increase your voltage you set manually before. (Offset mode, increase about 0,06125 V) and test again.
Do this until you have a stable overclock with good temps.

The safe temps of your CPU are:
max. safe core temp: 62° C
max. safe socket temp: 70° C

By the way:

As i look at CPU-Z though. the Core Speed jumps from 4113.61 MHz Multiplier x 20.0 to a Core Speed of 1439.76/1440 Multiplier x 7.0 back to 4113.61 MHz every few secs. Is that normal??
Click to expand...

This happens because of AMDs Cool and Quiet. It's trying to save power decreasing the multiplier.
You can disable this feature, as well as C6 State, APM and C1E.
But I highly recommend enabling it again once your overclock is stable and fine tuned to benefit from these power saving features. A good overclock also work with these energy saving settings.

Good luck!!!

I think I'm pushing the limit due to not having enough cooling.
I just noticed the Temp stressing at 4113.



it's 77*C what in the world...

I'm going to restore to defaults and run this stress test again.

That seems way to high for only OCing it just a bit.

Anyone know of a good program for fan control?

As soon as i figure this out, I'll try your method.

And i actually have Cool & Quiet off. as well as APM, and another setting.

Was mentioned in the video i watched.

Almost forgot. I'm stress testing it with prime95. that's 100% cpu usage. which i doubt I'll ever use.
The game i play doesn't require that much usage. Right now it's hovering around 18-20% usage.
But the main thing is to keep it under 55c right? or can it hover around 60 without causing issues?

I might buy a Cooling system.

For alittle over $100 this didn't look too bad

You could use "Speedfan" e.g. or the fan control options "AMD Overdrive" offers you.
With Overdrive you could also "write" very easy your own fan profile depending on CPU temps.
Anyways, you should be fine with the CPU-set fan speeds via PWN, e.g. I use the "Turbo" fan profile of the "Monitor" section in BIOS, with my Noctua cooler (very quiet and powerful), this setting gives me the best result with good temps in terms of noise level and fan speed.
