Phenom II X3 working as a Quad-core

**spitfire939** · 02-22-2009, 09:27 PM

Numerous users of Phenom II X3 (Heka) reported that they could enable the disabled core by just setting ACC to 'Per core' or 'Auto'mode in Bios.

to unfold the pics.

Everyone who could enable the core was using a 790GX chipset motherboard with SB750 southbridge - most being Biostar TA790GX 128M, and a CPU manufactured in week 0904.

Can anyone here try this and tell me the result?

Now that would be really funny!

Maybe they should call it X3 710 GTO2....

show us validated CPU-Z link please

I am interested
Since the CPU dealer with my 7750BE allows me to trade-in "old" model and add $$$$ for newer product
Maybe I should get my hands on one and see

I'll find out tuesday or wed if it works with 790 FXB/X3 720,just flashed to the latest DFI bios for Deneb in anticipation. Got some 8500 DDR2 also.

**spitfire939** · 02-23-2009, 01:10 AM

Seems like it only works on 790GX + SB750 Motherboards and 0904 CPU.

I don't have the CPU, still waiting for more info...

ASRock AOD790GX/128MB (720BE)
Gigabyte MA790GP-DS4H (720BE)
Biostar TA790GX 128M (710)
Biostar TA790GX XE (720BE, 710)

These are the motherboards that are confirmed... anyone have one of these?

A user over at OCUK has done this although even at 1Ghz couldn't get all 4 cores prime stable

Some CPUs runs perfectly at around ~3.5G, some at stock, while ~20% being unstable at stock clock speed, I guess.

Here's the test result of 8 CPUs. 6 of them could be transformed into a quadcore.

CPUZ 720 running as Quad..

Just hours ago, we found that the Koreans tested the Phenom II X3 710 can be hacked into a quad core by enabling the ACC in BIOS.

Likewise, the Tri Core X3 720 Black edition can be enabled the same way. Here is our article to prove that it works.

**richierich** · 02-23-2009, 09:38 AM

Anyone else want to try this??? I'm too tempted.

**SoF** · 02-23-2009, 03:26 PM

that sounds very interesting...now only figure out how to manage it on DFI or Foxconn Mobo

Foxconn won't boot with ACC auto on PII, DFI not tested in deep yet.

**G0ldBr1ck** · 02-23-2009, 03:54 PM

I may have to pick one up to try it in my AsRock board, It has working ACC.

ACC was such a mystical thing already, now this makes it even more so!! Does anyone understand WTH ACC is doing?

Auto Core Config?

**dehx** · 02-23-2009, 06:52 PM

I have the right stepping and the same chipset they recommend for this:

Phenom II X3 720 BE (CACZC), and a Asus M3A78-T (780GX / SB750).

I tried setting the ACC mode to Auto / Per Core and All Cores... interestingly, on per core, it shows cores 0,1,2,3 (4 cores total) to do ACC on, but on either of these settings, when I rebooted, it still said Phenom II X3 720, no 4th core upon booting into windows.

Either:

1.) This is an elaborate hoax, anyone using a good ********* can spoof CPU-Z validations, or...
2.) The 4th core is only good in a very few of these..

**AgentGOD** · 02-23-2009, 07:32 PM

It's supposed to still say Phenom II X3 720. You check CPUZ to see how many cores are active.

**richierich** · 02-23-2009, 07:47 PM

So far only ASRock and Biostar 790 + 750SB mobos have been confirmed. So far people with Asus boards have shown negative results.

Oh and in that video the guy's processor turned into 20 (instead of 720)

**G0ldBr1ck** · 02-23-2009, 08:02 PM

well, anyone want to buy my AsRock board than? I know ill just stick to buying quads and im about done with AM2+ so......

Have you tryied to remove "Processors" in "device manager" in windows and rebooted?
