Hey ComputerRestore, lovely guide, I just said to myself "If I only searched Bulldozer Overclock Asus Motherboard" I'd have found this on my own, instead another poster on another forum tipped me. Searching FX-8120 Asus M5A99FX Pro R2.0 doesn't come up with much, more generic search terms win this round.

I've OCed my 8120 on and off for the past year, so its seasoned, but I never followed the guide which apparently was my problem getting over 4.2Ghz. On the small FFTs, I complete 7 tests in 11 minutes at 4.4Ghz (24x200) at stock 1.35V. I'm using Cooler Master Seidon 120M water block, and on test 1, my CPU Temperature skyrockets up to 79C by Test 3. My Fan Expert is set to hit 100% at 62C so I'm at max cooling. But 79C is ceiling for the test, and temps slowly drop to 67C range for the last 4-5 minutes. Using Arctic Silver MX-4 paste (free after rebate). Should I upgrade the paste or just settle for stock voltage OC? I'm actually scared of running Blend overnight only to wake up to an overcooked PC.

I know I was told that bulldozers need core temps lower than socket temps but am I good when it is even? Warning: Spoiler! (Click to show)
Now currently I started Boinc crunching again for the rest of the event. I have to decide when it is over with whether I need to let the TIM cure for a time or if I should start my over clocking over immediately and see if my stability is any better. I have the "80-way Thermal Interface Material Performance Test" link so I can do the research on my TIM whether if it does have a minimum cure time. I can do that on my own. Only thing I don't know is whether I have to be at stock clocks the whole time it takes to cure. I will do what research I can. I just don't know how I was able to get to a cool and stable 4.4 GHz on my 8120 immediately after I finished following this guide and not being satisfied until I could make 4.5 GHz I lost my footage and barely make a hot but stable 4.2 GHz since then. Any advice is welcome.

For the cure time on your Thermal Paste, you can use whatever settings you want as long as the CPU isn't getting too hot. (over 62 Celsius)
I really can't understand your high temps. At 4.2Ghz you should be around 45 Celsius under load with that cooler.

So you are using the Corsair Fans in Push/Pull?
The fans are plugged into the water block so the water block can control the fan speed?
All the lights are lit up on the water block indicating that it will offer maximum cooling?

Lol, I tried to make it easy to find when searching.

Couple questions:
- are you going by the CPU Temp of the Asus Suite? If you are, then that is the listing for the Socket Temperature. You should download a program like HWMonitor so you can view the Socket Temps (Max ~70 Celsius) as well as the Core Temp (aka Package Temp Max 62 Celsius)
- Do you have another fan to add for push/pull on your Radiator?

MX-4 paste is really good. You should be able to get a decent OC out of your rig with that cooler.
If you find that your Core Temps are ok, and you're just reading the Socket Temps. You can add a fan to the VRM's and behind your motherboard to blow on the socket to lower temps even more.

Good Luck.

Corsair fans are connected and controlled by the motherboard dc fan controller. Fans are push/pull out the back of the case. All other fans are intake (2 top, 2 front, 1 left panel, 1 right blowing the cpu socket. The fans levels are maxed (I turn off the controller speed settings) when ocing or folding. I go silent speed or standard speed on mb controller for everyday use. The water block contoller lights were always on full (all 3 lights) though I must admit the lights aren't showing since yesterday when I accidentally pull the cables out of the power connector. Nothing really broke on it and I confirmed with my other pc's h80 setup. I can confirm the pump is working and there is water pressure still. Worse case scenario I trade out pc 2's h80 with my pc 1 (this one's) that I am working on.

Now I did my research about the TIM application and came up with this link for these special instructions for Antec Formula 7 Nano Diamond Thermal Compound. http://www.antec.com/specs/instruction4.html.
Quote:
1. Remove any thermal pads or other compound from the heat sink and the CPU core surfaces.
Use a LINT FREE cloth and low residual solvent such as isopropyl alcohol or acetone (nail polish remover) to clean the mating surfaces completely. Make absolutely sure the surfaces are free of foreign materials such as old compound, a hair, piece of lint or oil from fingers. Note: Never use any oil or petroleum based cleaners (WD-40, citrus based grease removers and other automotive degreasers) to clean the surfaces.
2. Put a finger into a clean plastic bag and apply a small amount of Silver Thermal Compound to the outside of the bag. To apply the compound, use a circular motion to rub the compound onto the base of the heat sink where the CPU core will contact it. Use a LINT FREE cloth to clean the surface again.
DO NOT use any solvent or fluid this time.
3. Slowly and carefully squeeze about 1/2 size of an uncooked grain of white rice or 1/4 of a BB to the CPU core.
4. Use a razor blade or the clean edge of a piece of paper to spread the compound over the core. Note: DO NOT use your finger to apply or smooth the compound.
5. Follow the manufacturer's instructions to secure the heat sink. Minimize any "Twisting" or lateral "Sliding".

Craziest instructions I have ever heard of but I guess I have to try it. I just hope I have the TIM to spare.

Thank you for clarifying. I was using both AiSuite and HWMonitor. My Package temp maxed at 51C, so I am ecstatic about the cooling and the MX-4 paste. I did hook the radiator onto my case fan that is blowing out while the CM fan is blowing into the radiator.

I am going to pull the stock CPU cooler fan off my A10-5700 as I just installed it in my HTPC and used my old air blower (Zalman) because that tiny fan is A) super loud and B) the APU gets too hot. Although, not I think its the board that is too hot since you cleared up what CPU temp on the board means within HWMonitor! That should get the socket temp down and appease my Probe II when the socket gets over 70C!

On your original post, you don't mention *how* to inch up the voltage or multiplier when stress testing. You might want to add that TurboV EVO does a nice job on CPU tweaks and include the disclaimer to log the results somewhere so when the PC crashes, you can save the highest stable values into the BIOS instead of loading the OC profile upon boot.
I personally like to boot at 3.8Ghz, OC with TurboV when I need max output, and revert my profile back when I don't need it anymore. Only trouble there is if you are doing massive voltage jumps or FSB / Multiplier jumps, you might want to phase in your clocks / volts as it can be unstable.

On a sidenote, I am still doing some testing with the "DRAM VREF CA ON CPU" setting. It seems to make some difference, but won't tell for sure, until I have some accurate results.

Those are some nice temps, great work.

I thought about doing a section for TurboV, as it would speed up the process of having to go back into the BIOS for each increase, but I didn't want to complicate things too much. That, and I haven't used TurboV enough to help with any issues that may arise out of using it.

That video is awesome. Personally I like to put mine through the dishwasher to get the dust off. (<-Joking)
I've actually been looking for the video that was linked at the end, as it was one of the best representations for applying TIM. Now I can link it to my guide, thanks for finding it.

I wish I could help more with those DRAM VREF settings, but only the CHV boards have them. Although I asked Asus to sponsor one to me for this guide, but that was a no go. doh.gif

Joined to thank you for this thread, was having all kinds of problems, couldn't get my FX-8350 stable above 4.5 (lots of freezing)... Spent 10 minutes on your thread, and now upto 4.7GHz easily. My ambient temps are a little high, so socket is 70c Max, Cores 57. I taped the AMD stock fan behind my mobo which helped bring down the skyrocketing socket temps! Thinking about just putting a full 120mm fan back there now if it fits lolol.

Vcore is 1.5v though, couldn't get stable on blend without it. Seen someone else with the exact same issue on this thread. However I use an M5A99X Evo R2. I will try raising the NB voltage later to see if it helps.

Cheers for the guide again, going to keep pushing it for a few days and see if I can't reach 4.8 stable at least.

EDIT: Failed custom blend test after the first 16 minutes in a couple tests, raising NB voltage did nothing. Retried with vcore at 1.512 volts and is now stable past that mark.

Thanks for this thread that help me understand a lot how piledriver works!
Currently I have 8350 + Sabertooth r2 + H60 and I got some questions that how someone could help.

What is the default voltage for stock speed? I disabled all power saving feature and have low lcc, Cpuz and Asus utilities both read 1.284 at stock, is it a bit low? (but it is perfectly stable)

I didn't touch that voltage while tune up only LLC to ultra high, I can get it stable at 4.5GHz with 1.332v at 56c for core and socket at 68C, I will try to put a fan to blow on vcore area. Seems like 4.8ghz is achievable if I can control the temp!

Good to know the video was useful. I saw you added the new part. There was a picture of delidded CPU, I was thinking you maybe could use this picture instead. A bit better reference I think.

Sorry to hear about ASUS not sponsoring you :/
But if you had gotten the board my life would be so much more boring biggrin.gif
At the moment I have stopped testing DRAM VREF settings. Just needed a brake and play some DayZ with my friends rolleyes.gif
But when I resume with it and come to somekind of a conclusion I will definetly post it here.

If you get it above 4.7GHz without raising voltages please do let me know! Otherwise I'm probably keeping mine at this level too. I'll try tweaking more later and see if I can get to 4.8 @1.512 which should be reasonable..
