8350 owners: overclock potential?

thank you for you help SkateZilla

Skatezilla,

Can you get some screenshots of your voltages so I have an idea of a jumping off point?

Thanks.

it changes for everyone, no chip is the same.

 

I'd suggest Starting with stock voltage, and then moving MP up 1 click at a time, and bench/test until you are no longer Prime95 Stable. After that, increase mV from the stock 1 or 2 ticks at a time, I wouldn't go over 1.5v though without significant cooling.

 

Take notes of your starting settings, then take notes of each change.

 

once you find your "target OC", start lowering the MP and upping the FSB 5 or so MHz at a time to stay close to your target, and again, after each change, test/bench the CPU to test it under load.

I just found this read.

Just finished installing my Watercooler setup. I'm gonna have a go at it using these voltages as a guide.

That really is a good read. the chart on page 18 gives max voltages that you won't find anywhere else.

so I'm at 5Ghz (238x21) at 1.48125 volts prime stable for an hour. Temp is mid 50's. It show as 238.8 for a clock of 5.014Ghz so I've achieved my goal of a +5Ghz machine. Now the GPU is the loudest thing in my machine. I'l have to fix that with another radiator and GPU cooler :music_whistling:

I MAXED out everything in game and never go below 20FPS. I turned off HDR (don't like it), turned the AA to 4x, and halfed the sliders on the right for an acceptable 45-70 FPS.

I flew for the first time in three weeks last night. Man I love this sim...

I'll take some screenshots of my BIOS settings and post them later.

I've played with Closed Loop Water on GPUs,

 

I used Zipties to mount the water block to it, the main thing you need to worry about is Thermal Paste, especially for AMD 7900 Series, as you'd need a shim in between the GPU and Waterblock to make contact, you need the best Thermal Paste, that's non conductive (MX-4 I think is what I used.), I left the plastic heatsink/spreader on my RAM and VRM and my side fan blows on it nicely.

I plan on using a Swiftech full card GPU cooler and add a 120mm full copper radiator piped into the system I have. I've listed (and sold some) of my previous components on ebay. I should get enough to cover the cost of the additional water cooling stuff. I also need to buy a 240mm Pure Wing fan as I can hear the one I have over the 120mm Pure Wing radiator and case fans I have. I should end up with an ultra quiet, ultra fast, machine.
