post #2331 of 8112
Im totally stable at 1.375v (1.42v load) on my FX-4100 @ 4.4Ghz. 4.5Ghz needs 1.425v (1.46v load), and 4.6Ghz needs 1.475v (1.52v load)

Voltage requirements seem to go up exponentially in the 4.6ghz to 4.7ghz range. Im fairly certain you should push volts to the low 1.4v range for 4.5Ghz, though if you plan on going further be ready to crank the vcore up more.

Memory should have nothing to do with a core crapping out. It all points back to vcore in my experience.

I have tried raising the cpu/nb to 1.4, 1.3 1.25v
And memory to 1.55 from 1.5v
Lowering mem speeds to 1333mhz and loosening the timmings, ( i loaded 4gb specs in bios).
But i cant stop my cores from crashing, i believe its due to 16gb ram can any1 help me solve this?
Or should i just give it MOAR Vcore? Since small FFT didnt fail i dont this its necessary.

EDIT1:
It seems that raising the Vcore to 1.392v load and lowering frequency and loosening timmings memory worked, still testing though.
EDIT2: Spoke too soon, core #7 failed.

It's trcky. I couldn't get past 4.6 with 16g RAM...
If I remember well, i got something like:
vcore 1.4375
nb: 1.2
cpu/nb: 1.3
ram: 1.525

Also, in ram timings, try setting it to 2T.

Good luck.

Not sure if the guy is a member here but he has an fx8120 and 2xhd6990's and getting 97% gpu usage outta them. His 8120 is oc to 4.6ghz I believe. He is the one with the thread "my wife would not approve". If you see this message do you mind running some settings by us and some stats with your experience? All you hear on OCN is how bad BD sucks in high range crossfire and it doesn't seem quite to be the case with him. Sorry I'm on phone or Id know his name. Peace

In benchmarks it will usually not be an issue, certain games like SC2 and Civ 5 need lots of single thread CPU horsepower. Im not sure what other games fall into this category, but Ive seen Crysis 1 and a few others having issues.

Hmm that's strange. A guy on here has his 8120 at 4.8 I believe 24/7 and plays bf3 no problem. Thanks for replying btw. Hey guys remember I posted on here an email I got from AMD rep stating that he didn't think the 3200 series Opteron was gonna be on AM3+? Well I wrote them back and another rep replied back and said, "I would trust rumors normally if it came from multiple reputable sites" (which it is listed on cpu world and others for am3+) and he said, "I do not agree with my colleague on the last message" (which said he thinks it is gonna be on server platform) So I feel he was telling me that it is true and IS coming to consumer platform am3+ and he also said he doesn't wanna let down a great customer like myself but there are things to which he can not say and they have rules and regs and he apologized. So what do you all think? I'm thinking I'm going to own a 3280 he Opteron reeeaaal soon.

Thought I'd try some OC on my FX 8150 since I switch to an H100 from normal Air (Artic Cooling Xtreme) I was able to hit 4.7Ghz Prime Stable with the Artic Cooling but my Cinebench 11.5 was capped out at 7.32 for CPU score. I thought it was due to the temperatures causing the CPU signals to break down.

So, after installing the Corsair H100, temperatures are 15-20 Degrees cooler. Time to OC
First OC. 4.6Ghz (23X Multi, FSB 200) Cinebench 7.55!!!
2nd OC. 4.8Ghz (24X Multi, FSB 200) Cinebench 7.85
3rd OC. 5.0Ghz (25X Multi, FSB 200) Cinebench 8.17

I thought temperatures may be an issue, it seems that thermal breakdown on these CPU's is bad.
I guess that why some were advertised as coming with a closed loop water cooling.

Since it's winter here, I tought I'd do a little Canadian Overclocking (Outside style -10 Celsius)

5.2Ghz (25X Multi, FSB 208 1.675 Volts on CPU) Cinebench 8.45

Tried for 5.4 @ 1.7v But my computer was freezing in the Bios. Not sure if something on the motherboard was getting too cold. Would freeze even after clearing CMOS. Took it back inside for a few minutes. Ok now lol. I just really wanted to get 9+ on Cinebench.

Will post my screenies later as I am doing this at work

Ninja Edit: Had to change my Cinebench scores as I had to guess what they were without my computer. They are now correct
