ACC has got to be on.... Also... memnoch u add rep by clicking on the thing that says rep+ at the bottom of the person's post...... I had trouble with that at first too....

RendoR, the Athlon X2 250 is a Regor. The Athlon X2 550BE is a Callisto. I'm really not to sure why your 550 is showing up as a Regor What application is displaying this? Technically speaking these are quad-core processors with two disabled cores and disabled L2+L3 cache (depending on model). I believe there is also a Athlon X2 545. It's slightly slower than the 550BE.

Memnoch, that is correct buddy

I have always had C1E disabled. I also can't get into the BIOS right now as I'm reinstalling Windows.

I've also found another problem. I was told to boot into safe mode, uninstall the CPU, then boot into Windows normally. Well, I can't get into safe mode period, even with the BIOS set to factory defaults. When I choose to boot into safe mode, a few system files load and then it freezes right after crcdisk.sys is loaded. After finding that out, I reinstalled Windows and the same thing happens again. So now I'm reinstalling Windows for the second time today (I'm using a different copy this time), I hope this fixes it. I almost have a feeling my HDD is bad.

I KNOW that this chip will fully unlock though. I've never gotten a BSOD when ACC is set to auto, all cores, or per core. It just won't load the "Windows green loading bar" stage of boot up. Could the motherboard be defective? RAM? CPU?

Other than the, the chip works perfectly.

Keep upping it but don't go past 1.4 Vcore. It may very well be that your locked cores are unstable and no amount of volts will change it. Good luck.

ImmortalKenny

So what would 1.4v translate into mV? Apparently +200mV is around 1.51v.

Regardless, I'm trying to get my OS issues solved, then I'll go back to trying to unlock the other cores.

thlnk3r, Come to think of it, my cpu was listed as a Regor with the F2 Bios. Now it's listed as Phenom II X4 B50 processor. It's the same in Everest and CPU-Z. It's shows up as a Deneb now. So it's a Callisto not a Deneb?

I think I have an idea of why HondaGuy has temps. I noticed on his screenshots, his CPU is listed as a DualCore AMD Athlon X2 (Regor, Socket AM2+). That's his benchmark in Everest, it says v5.02.1750. Unless HondaGuy was using another CPU for that screenshot? I was under the impression it was for the 550. Can you clarify that HondaGuy? The question is, if his 550 is showing up as an Athlon X2, why is mine showing up as an X4 B50? What's B50 anyway?

I bumped the NB video voltage to + 275 and set the NB to 2800mhz. I started the stability test and it went red almost immediately. Hopefully nothing is damaged or anything. I'm kinda freaked out though.

ImmortalKenny, if you suspect your drive is failing then I recommend downloading the Seagate Seatools. Download the DOS tools and burn them to a bootable CD. Make sure to run the "full" surface scan.

It's not guaranteed that you'll be able to unlock the disabled cores. As another member just mentioned, those cores may actually be defective. Remember there's a reason why it's a dual-core

RendoR, the 550BE is a Callisto. Technically these are all identical to Deneb (quad-cores), they just have two disabled cores. I believe the reason why it's showing up as a B50 is because it's been "unlocked" using the ACC feature.

What stability test did you run where it displayed "red"? This is probably just a sign of instability with the NB Frequency. Really the only thing that can damage a component is excessive voltage for long periods of time.

Good luck

If you are having issues with your OS install, this is my suggestion. Turn off the pc, and restart. Go directly into the BIOS and set it to the "fail safe defaults", then double check to make sure that ACC is off. Once verified, turn the pc off again, turn the psu off at switch on the back, unplug the psu, then pump the power button a couple of times to ensure all power has been drained. Then pull your CMOS batter out, and let it sit for about 2-5 minutes. Reinstall the CMOS battery, plug your psu back in, flip the switch, power back on, and load your OS. Don't even go into the BIOS yet at all, just try and install the OS.

If it gives you a CMOS bad message before it get's to the boot of the cd for the os, go into the bios but DON'T enable any of the advance features, just set the correct date, and reboot. Then proceed to install the OS. This should ensure that the PC is using the chip as a dual core, and everything at default, and you should be able to install the OS without any more issues.

Once the OS is installed, go ahead and uninstall the CPU from device manager, reboot, enable the advanced menu features, set the ACC to Auto, up the CPU VID Special Add to 75mv to start, double check to make sure your ram is at the correct voltage it's rated to run at, then reboot again.

See if that works, and get back to me!

Oh and thlnk3r here is the 2 that I like the best, take your pick

Clock speed 3930.6 or 3815.1
FSB x Multi 224 x 17.5 or 218 x 17.5
Vcore 1.44v or 1.375
RAM speed 900 or 872
HT Link 2695 or 2616
Motherboard Gigabyte GA-MA790GP-UD4H
Cooling method Xigmatek DarkKnight

thlk3r.. I was running the stability test in Everest Ultimate v1750. It went red in 2 seconds and said there was a hardware failure. I went back into the Bios and set the NB frequency and voltage back to normal. Everything was fine until I set the multiplier back to normal. For some reason it wouldn't boot, it just kept revving up. I had to jumper the CMOS and start from scratch.

Is there a point where you absolutely have to add voltage to the vcore? Like 3.7ghz or so? Just curious... It was weird though. Everything was fine until I put the multiplier back to normal. Then it crashed on me for the first time?

You're right though, there's definitely a reason why these are dual cores I guarantee it.

vincentfkc

HT 2600?

NB 2600?

how is ur NB voltage?

and can u see ur benchmark of everest of memory
