MA770-UD3 Phenom II x2 555 BE Unlock help

[Distreiga]

Hi guys,

New to the unlocking business.

I've got a GA-MA770-UD3 and a Phenom II x2 555 BE.

I've set ACC to auto and the mobo is in hybrid mode. Computer posts fine and detects Phenom II x4.

Once booted into Windows 7 32 bit, CPU-Z says I've still only got two cores. Checked msconfig and it doesn't show 4 cores in the boot area.

Any suggestions?

Thanks

Might want to try this.

'Some users have been reported seeing the "X4" designation, but no unlocked cores when verifying through CPU-Z.  Please ensure that you have set Windows to use all 4 cores by going to "msconfig --> Boot --> Advanced Options --> Number of Processors." If you still don't see unlocked cores, then most likely that your disabled cores are defective'

As usual, at your own risk etc.

You must also set the BIOS to accept the unlocked cores. You need to make the setting to CPU unlocking to "enabled"

Hi guys,

Thanks for the reply. My issue has been solved.

After doing some research I found that I had to uncheck the box in msconfig, boot, advanced options to choose how many cores I had.

Here's the proofs on yet another successful unlock. Still need to stress test though.

Happy that you managed to sort through it and thanks for the feedback. Good luck with the stress testing.

When I'm doing the stress testing, how hot should I let the cpu to get with Prime 95? Even with the cores unlocked, my CPU still reads the temperature of the core. Easy tune 6 reports I'm around 33-34C Idle. I've got a Coolermaster Hyper 212.

Thanks,

These Phenom CPU's shouldn't really be allowed to go above 62° C so you will need to keep a close eye on temps, especially with the unlocked cores now running.

[Distreiga]

I'm going to go on a hunch here and say that if after 2 Hours Prime 95 has me running still at 50C It'll be that way the whole way through and I can run the stress test overnight.

I do have an alarm set to go if I get over 60C.

[Dark Mantis]

That should be ok then I would think but it might pay you to use another program as well to check the temps. You could also use Core Temp it is a very well respected program. Although personally I don't like to run things when I am not there to watch them.

[Distreiga]

How long would you run Prime 95 then? 12 hours while watching it?

Seems a little much to me haha. What am I supposed to do while it's running?

[Dark Mantis]

Depends on how sure you want your results to be. No pain no gain.

[absic]

Sorry, I made a mistake and have just double checked the Max temp of the X2 CPU that you are using and it is 70°C not 62°C as I previously mentioned.

[Distreiga]

Thanks absic. That's 20C of headroom during a stress test... Makes me feel safe

[absic]

No worries!  It's always nice to know what you have to play with, especially when overclocking.

Just to note for other users seeking to see if they can unlock with the same hardware, I found it very difficult to find any information regarding the motherboard I am using because it's the most recent revision of the model.

So again, unlocking the Phenom II x2 Black Edition 555 can work on the GA-MA770-UD3 Rev 2.1.
