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 very much, I'm glad it was able to help you. Looks like you're getting really good results with that CPU. It looks like you have a high stock voltage, so don't be too concerned if others can hit the same clock at lower voltages.

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!

That voltage is normal. Pretty well every CPU is different. I've seen FX 8350's from 1.28-1.41v for stock voltages.

The drawback (as you are witnessing) with a low stock voltage, is that temps get crazy really quick. You'll hit the thermal limit way before you hit the voltage limit of 1.55v.

That CPU is more suited to Custom Water Cooling or Liquid Nitrogen.

You might be able to hit 4.8Ghz with a larger All-in-one water cooler (H80i, H100i, etc) but you should be ok at 4.6Ghz with the H60. So it depends how much that extra 200Mhz is worth to you I guess.

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.

I will use that picture, thanks. It fits much better to this thread than a delidded Ivy. Yeah, the Asus Sponsor was a long shot, lol. If they did, then I was going to get the EK full board blocks and see how much better I could OC my Chip. (my 2nd one was a 1.28v stock voltage one and it ran HOT)

My fx 6300 needed nearly 1.52 for 4.8ghz im going to drop my ram from oc 1866mhz and start adjusting the multiplier see if i can hit 5 maybe more lol

I rigged my APU heatsink's fan over the 990fx chip by an elastic band around the middle of the fan and a twisty tie from the bank to my Seidon's water tubing (stiff like metal). My Prime95 testing ran 8-10 degrees cooler, with minimal noise. I hooked it up to the 990fx Pro R2.0's 'opt CPU fan' plug. My Armor A90's top 200mm fan started clicking annoyingly about 3 months ago, and now that I'm back to OCing, I get a new one tomorrow / Monday and will pursue higher clocks with the 1.45V range on the FX-8120 to climb to 4.8Ghz land.

Probably the wrong thread, but anyone have feedback with OCing 2x8GB 1600Mhz RAM to 1866Mhz? Does Bulldozer like higher RAM frequency? The APU thrives with 1866Mhz - 2133Mhz, and throttles at 1600Mhz for pretty well documented reasons.

Bulldozer/Piledriver can push really high Memory Frequencies, but it actually benefits more from tight timings.
You could probably try your Ram at 1866Mhz 9-11-9-24 and then just increase the DRAM voltage.

I have my G.Skills F3-12800CL9-4GBXL 1600 MHz XMP running at 1866 MHz with 10-10-10-24 timings, prime stable biggrin.gif

Im running at 1866 with 9-9-9-24-1t, buts its some 2400 mhz trident ram, id like to get it in the 2000 mhz range, but i will probably need to drop the 1t

You are so right, this time I tried something different, with all LLC at regular, the drop is pretty nasty, if I set it to 1.41, it will gives 1.35v, at this voltage I can get 4.6 ghz stable, but I hit the thermal wall, socket at 70C, core at 61C and vcore at 80C!!! The temp really goes crazy!
What its the safe temp for vcore bTw?

vCore is the VRM reading. Below 85 Celsius is good. Adding a fan can drop the temps to 50 which will make the power production more effecient.

I lost most all stability along with higher core temps. This 3rd time reseating the cpu I finally dropped the temps of core and socket where they used to be. Except then I was at 4.4 GHz and no higher than 55*C on either socket or core. Now I am forcing a 4.3GHz oc and barely getting my cores in at 61*C and socket 55*C. I don't know if I am failing miserably with the TIM or what but I was doing a lot better when I was following your guide in the beginning and then I started messing with things trying to get to a golden overclock (to me atleast) of 4.5GHz. I don't know how much of my TIM I have left and yes I know it only takes the smallest amount but I was just not getting it to spread evenly. I don't know if I should try a reseat again and see how it was spread or accept what I have now. With the temps that I have now do I have the chance to get considerably cooler with reseating once or twice more? I never had this trouble before but I think the difference is the consistency with the TIM. I had more liquidly TIM in the past and now the stuff I have is real thick. though it had a good review. What do you think?

wow my thermalright sb-e extreme is allowing me 4.5ghz with lower temps, yeah arctic silver is good, although I used ceramique ii, quite thick mix, used thermalrights tim that came with the cooler for this build, 3 rice grain sized amounts on cooler plate and same on cpu then used a plastic card (library not bank but same material and thickness) to spread into a thin layer on both cpu and cooler, this makes sure its smooth and evenly spread, then seated the cooler, no need to remove to check spread as you have made sure there is an even coating with the card, hope this helps

Eureka! Finally... How is folding at full load and 4.0 GHz at 39*C? I haven't responded back to this thread because I wanted to get it right unless I was all wrong which was real close. I did many reapplications of the Antec Formula 7 TIM and could not get the temps down that was reaching max recommended temps. I tried the grain of rice in the center and it would not spread out. I tried spreading it thin and thinner with a razor blade and I would get max temps that wouldn't go down. I tried my finger in plastic and this stuff would not come off the plastic as I was trying to apply it. This is really thick stuff and hard to spread.I must of had a great amount of this TIM. Not because I was using a lot but because I must have tried in so many different ways to get this stuff to spread evenly. Finally I was rdy to buy arctic 5 at the home town radio shack but thought I would give it one more try. I applied it in a "x" form on my cpu from the recommendation here Finally low temps were coming. I burned it in for another 12 hours. This morning I tried folding with it. The core temps came to be 39 to 40*C. The Socket temps @ 45*C thanks to this thread's advice to place a stock cpu fan to blow air on the bottom of the socket. I am feeling pretty good about trying to reach my 4.5 GHz goal thanks to this thread but waiting for my FAH work unit to finish. Wish me luck.

Oh good. That gives you much more headroom to play with. I'm really glad you got it sorted out, and that it was just the TIM that wasn't playing nice. Temps look to be spot on for that setup now.

Looking forward to how far you can push it now. biggrin.gif
