If the 8150s are anything like the 8120s where the lower the stock voltage the worse they overclock yours is going to be a very poor overclocker. But the only way to find out is to try I guess. And then we will know if they follow the same patten.
Make sure you have APM disabled since that drops the voltage down when its throttling the cores. drops voltage to 1.14v range so it sounds like thats whats causing it to drop.

I remember reading about high vid = better oc'ing as well, but my 8120 had a high stock voltage and I couldn't get it past 4.5GHz with 1.47v. If I upped the voltage anymore I couldn't keep it under 61c on the cores. So I sort of discounted that theory but maybe I just had a weird one

Supposedly 1.3v and up is supposed to be pretty good but that wasn't the case for me.

This was truely a pain in the ass.... It Refuses to pass Intel burn test, prime 95, etc. But will run cinebench flawless everytime, i'm not keen on sending 1.6V through this baby and had to fiddle with almost every other setting on the over voltage bios page.
Hope you enjoy!

Can we see a score. You posted a ss of cinebench without a score. Lets see some results.

Also the voltage seems to drop a bit even at full load, seen it at 1.12v while still at 3.6GHz. Temps seem about the same. The chips are definitely better binned than 8120s, by a country mile it seems

Quote below is true. It has been found that the best overclocking FX chips are the ones with stock votlage between 1.3-1.35v. Anything lower or higher are found to have poor overclocking capabilities. This is true in most cases, not all. Chips with lower VID can be overclocked with lower voltages but they hit there voltage wall early and they also get really hot when overclcoked. Chips with higher VID need a lot of voltage to overclock but they wont hit their voltage wall for a while and also they tend to stay pretty cool when overclocked. You will probably find that the max overclock for your 8120 is higher than your 8150. Not saying that this is whats going to happen but it does happen in most cases.

Also like stated in quote below it says that your voltage drop is due to apm but it is more than likely your LLC. The apm is used to throttle your cpu underload to keep power consumption low. When you overclock you want to increase your LLC and disable all power saving features on the chip. This is the best way to start overclocking. Make sure you have the latest bios. Max Safe volttages for these chips are right around 1.55v. Max temps for these chips are 61C. HW Monitor works prettty good with Bulldozer chips. Prime95 is probably the best stability test you can use for these chips too. See how high you can overclock your chips and you will probably find that your 8120 overclocks higher than the 8150 but make sure you stay within recommended voltages and temps of the chips. From what has been found in most cases, the majority of the people that know about BD they would say that your 8120 is a better binned chip than your 8150.

Let us know your results. We always like to see BD updates.

Fixed, i'd truly push it farther, but it won't even boot correctly @ 1.6v past 5.1GHz...... So, 5GHZ is suffice for me. i know it's not smart too keep such a heft OC on 24/7, but cinebench passes EVERYTIME, back to back to back, Plays all my games flawlessly no crashes, recording, youtube, Multiple tabs of Google chrome open, etc all at once. But just REFUSES to run intel burn test/ Prime 95, etc still like i said. But hope this gives some positive results to some of you looking forward to a BD chip/ PD/ or future Zambezi Chips!

And from personal experience with this thing now @ 5GHZ.... is when this baby truly start to show it's name "Bulldozer". - Sincerely, nate.

Most everyone will tell you that even though cinebench passes that it is not stable. IMO if you can run Prime95 for an hour then that is stable enough for me. But if you cant run it for at least 15 min it will cause problems for you. I am not telling you what to do but I would recommend not running that for 24/7.

Especially if all you do is gaming and basic application use then you can run 4.8Ghz or even 4.6 and not notice any difference in the performance with that kind of use. In some cases when your system is not stable you can erase your drives and lose all your data. This is why it is recommend to have a stable system. Cinebench doesnt really push the cpu like it should for a stability test. It is only a benchmark. The best thing to do is find the highest clock that can run prime for at least an hour (most people resommend at least 3 hours) and run with that. I garauntee you will not see any difference in performance if all you use your system for is gaming and everyday application tasks. Video editing/converting might show a little but not enough to take the risk of losing your data or causing harm to your chip. The only thing you would really see a difference in performance is like folding but that is actually more heavy on the cpu than cinebench and in some cases almost as heavy on the cpu as prime. So even if you did folding you wouldnt be able to if it cant run prime. If you can run prime at 5ghz for even 15min then thats not good.

I recommend getting your system stable and I garautee you wont see any performance difference with gaming or movies or music or web browsing.

I Got Big News For ASUS Crosshair V Formula Motherboard Owners

I have contacted ASUS pertaining to the CPU/NB LLC problem and it turns out that it is not the bios. It turn out the bios chip is faulty. He asked me when I got my board and I thought this was kind of weird so I asked him why he needed to know after I told him.

It turns out that Crosshair V Formula Motherboards that were purchased before a certain date have a faulty bios chip on them that is affected by the FX processors. He did not tell me any details but they are sending me a new bios chip that has been fixed for FX cpu's.

I am a little disappointed that I was not notified or contacted about this seeing that they know that I have this board with a 8120. He did not tell me the date of which the boards started being fitted with this fixed bios chip but if you have an FX processor with this board then I would recommend contacting them and requesting a fixed bios chip for the Bulldozer cpu. Hell, I would even do it if I didnt have a FX cpu. He did say that the boards that were sent out before a certain time had a faulty bios chip that was affected by the FX chips. Not exactly, but something right along those lines. If you have this board I would recommend calling them and asking about this cause you might not be getting the most performance out of your board and chip because of this. He did specify that it is with the Bulldozer chip but he did not exclude and chips. So I would call and find out if your board is eligible for a new bios chip. I purchased my board in october. I had to tell him that and the serial number to, i guess, see if my board was one of the ones sent out with a faulty bios chip. It turns out that it is and he said the new bios chip fixed for the FX chips will be delivered to me within a week. Nice customer service I might add. I dont know how or if this is going to increase performance or stability or anything like that and I will be sure to let you guys know once I install it.

So, IMO if you have a Crosshair V Formula mobo, then I recommend that you call ASUS (U.S. Toll Free - 1-812-282-2787) and find out if your board needs a new bios chip.

I am glad that I found this out. I dont know if the faulty one was damaging anything or decreasing the performance of my chip or affecting stability or what but a faulty bios chip needs to be replaced.

OP, I think you should post this on the first thread for other Crosshair V owners to see.

If you have any questions or concerns please feel free to ask.

Hope I could help you guys and I will notify everyone, once I install my the new bios chip, if there are any performance or stability changes with it.

ouch...lower VID chips usually have a harder time getting higher clocks.
