Did you reset your bios? If not, that is where you should start. After the reset, set your ram manually (not in auto), then go about trying to unlock.

Ok I did all the suggestions but no good. I even tried experimenting by putting my vcore all the way up to 1.80! It took but as soon as I ran Prime95....it freezes. Any other suggestions?

Put your bios back to factory defaults and run prime to get a baseline. Monitor your temps and confirm speeds of cpu and memory in cpuz. Also note what voltage your cpu runs at under load.

WHOA man. I don't know why anyone hasn't said this already, but what is your overclock (if any)???

1.8v is VERY high, way past the limit for vcore (max safe is 1.55v). You should NEVER set your vcore past that let alone to 1.8v, you're lucky you didn't fry it

I have the same chip (Phenom II x2 555 BE unlocked) running at 4ghz 24/7, well 4ghz on the first 3 cores and 3.7ghz on the last, and it's tested prime95 stable for 12hrs. I only use a vcore of 1.5, as well as loadline calibration of 0% and VDDA 2.8, so my vcore is about 1.49 idle and varies between 1.5, 1.52 and 1.55v under load.

Regardless, my chip needed NO voltage increase whatsoever from unlocking cores. The default volts (1.4v) was enough to unlock it AND overclock it up to 3.5ghz. Any higher than that needed a voltage increase.

I would agree with Badwrench,

Do this, note your vcore (on my C3 revision 555BE it is 1.4v, on a C2 550BE it was 1.35v). Leave it alone for the purposes of unlocking until you figure out how many stable cores you have, then try to overclock as high as you can stably without raising the voltage, only raise the voltage if you find it needs more.

Your BIOS and motherboard settings also matter.

For example you may have an option in unlocking method (ACC). Mine is disabled - per core - all cores - auto (unleashing mode - enable/disable)

For my system I just use "auto" and right below it a entry appears called unleashing mode, which I enable.

However I've read that on other motherboard brands it can be different and the 'unleashing mode' if present is unstable. In this instance, use 'all cores' or 'per core' instead.

There is also a setting on the same page, probably if you enable 'per core' unlocking that allows you to adjust the ACC threshold in increments of 2%- see this thread
http://www.overclock.net/t/397179/amd-advanced-clock-calibration-guide

Mine is set to every core -2%

Additionally you may also try updating your motherboard bios which may add some of these features if missing and will probably increase stability of unlocking in any case.

IF you try all of these options and none of them work and it still fails, that means you have either a bad/cheapo motherboard or simply a CPU that can't unlock.

Good luck.

Thanks man. Prime95 runs well with no errors when using stock voltage and just the 2 cores (everything set to default in BIOS). I havent even overclocked it at ll yet. The only thing i have done is try changing the voltage. Are you saying that I may need to overclock to get the cores working correctly? If so, do you know what exact option I need to raise for the overclock?

Ok good, no overclock.

No, you do NOT need to overclock to get the cores working. Getting the extra cores working first without overclocking or raising voltage at all should be the priority.

What you should do, is go in your bios and write down or describe to me the options there regarding ACC (advanced clock calibration, 'core unlocking'). As I said, it may have something to do with the ACC setting. Also, try to figure out what BIOS version you are running, and go to your mobo manufacturer's website and see if an updated BIOS is available (they usually improve stability).

As opposed to adding voltage unnecessarily you might try looking for a Loadline Calibration option in your bios- it will probably be set to auto if it exists, and adjusts between 0% and 100%. Set it to 0% (on). What this does is help with vdroop and supplies a more stable voltage to your processor idle and under load. It may actually be that you had too much voltage to the chip and too much voltage fluctuation, causing unreliability.

If you can try setting loadline to 0%, enable "per core" ACC and set them all (cores 0-3) to -2% (that's NEGATIVE 2% if it isnt clear), make sure your voltage is stock, then try running prime95.

Also, keep in mind your chip may NEVER be stable in prime95 with cores unlocked at all. This can actually be okay as long as your system is stable in day to day use doing what you need it to do. Yes, prime95 ensures stability, but I can guarantee you prime95 stresses the CPU in a way most modern games and web browsing never will. Unless you are running a mysql database server + Apache, compiling software, folding or running distributed computing applications, or doing processor intensive video encoding your CPU will probably never be stressed like it is in prime95. For example, I run folding@home on my cpu frequently, which loads it to 100% on all cores, however my temps only go to about 50c or so. Running prime95 it goes to 55c, which it never does in folding@home (read: folding stresses it less than prime95). Running intelburntest -linpack I've seen it go as high as 62c. For comparison, any modern 3d game my cpu only hits about 42c and never comes anywhere close to 100% load (Skyrim...) My point being that basically, just because it fails in prime95 with all 4 cores doesn't mean it isn't stable enough for daily use. Try unlocking and running whatever games or applications you plan on using, if it's a game play for a good hour, if you don't BSOD or get random reboots or lockups it's probably fine though not "completely" stable.

Everyone who says that 1.55 is max safe for phenom ii series, where do you get this from? heard it from a friend who heard it from a friend? or is it from experience? or just the conclusion that it handles a 10% increase from fabric max?

I has looked and looked and everyone just says 1.55 is max, 0, i mean ZERO i have talked to has tried going above or know anyone who has. I hasnt found 1 on the hole bloody internet who has destroyed his chip.

Just wondering how mutch volts destroy chips if cooled properly
post #18 of 46
What?? it is possible to run 3 cores on 1 speed and 1 on a diffrent speed?

Can i get my athlon x3 450 to run on 3 cores 4GHz and 1 core 3.7GHZ? HOW?

I got an 870a-ud3 motherboard...

My 4th core, witch was locked, is not in as good shape as the other 3 cores. so if it possible to run 3 cores on 4.2GHz and 1 on 3.7Ghz that would be amasing! than i can raise the speed and go down on the volts

It's from AMD I believe. 1.55 on air cooling under max load will go quite above the 58c temperature threshold (58c is supposedly the max for day to day operation. past this temperature, the system is way more likely to fail, and going high enough above it for a prolonged period of time can destroy the chip). Of course, you CAN go higher than 1.55 but there's no saying it will be stable. I mean, the people who got Phenom II's to 8ghz with li-ni and liquid helium probably went well past 1.55v; of course this is subjective and relevant to your particular chip, motherboard, cooling setup, etc. Looking at something like this, AMD lists a 720BE's voltage range from 0.850-1.425V. Then again, it is a kind of "word of mouth" thing based probably on experience of longtime overclockers and people who go to overclocking competitions using extreme methods, and probably electrical engineers. If you choose to ignore them and set your air cooled Phenom II to 2.0v and 7ghz and your rig and mobo catch on fire 5 seconds after POST, well, you'd wish you listened to the "popular" opinion. ;D

Yes, I do it with AMD Overdrive. However, you have an Athlon, and I don't believe it will work with it...though there may be a hacked version that will, or a registry hack, or another utility. Additionally it's only supposed to work with Black Edition chips. To be honest I don't know if there's any way to do it with Athlons, you may have to ask in another thread. I built this machine originally for around $500 in the beginning of 2010, and in doing so did a ton of research and made sure I 1) got a chip and mobo that would unlock and 2) got a black edition processor that would run AOD (Overdrive). All I know is it works with my system, as far as running it on Athlon you can try but I doubt it will work and I have no resources as to any workaround.

Basically what I do is set my important options I know I need in the BIOS, then have Windows apply my overclock profile as soon as I log in. Currently I'm pretty sure my BIOS is set 3.4ghz, vcore auto, VDDA 2.8, loadline 0%, Northbridge 14x (2800), CPU-NB Volts 1.4v. Then in AOD I have it set like

423

All I change is my vcore and multipliers. My system is not stable with my 4th core clocked to 4ghz, but it's survived prime95 for 12 hrs with core 4 at 3.7ghz and all the rest at 4ghz. Currently I'm working on 4.1ghz and possibly going to try 4.2ghz though my load heat goes up 5c just from that small jump so its unlikely..

Good luck

Man, you are giving so much helpful information. Thank you.

Here is a screenshot with my other 2 cores unlocked. I want to try the -2% decrements you talked about earlier but there doesnt seem to be an option for individual cores in the BIOS. Is it possible to do this with AMD Overdrive? Also, can you see anything I may be able to tweak in the screenshot that may give me more stability?

480


Also, with CPUZ, it shows my core voltage at 1.08......not sure why it reports that low

**edit** All was fine until playing a video while browsing. It froze again.
