Yeah..

I've tried both combinations..:mad:

Also i tried ACC->Per Core -2%/-4%/-6% etc & ACC->All Cores -2%.Nothing.

I've also flashed to previous BIOS 1.30..with no luck.

The mobo posts only after a CMOS.

===========================================

I know that CACYC's L3 unlocks..here is a link at a greek forum

7/10 CPU from the same shop unlocked successfully (+L3 cache)..the 3 ones have the same behavior (no boot).

Do you keep your L3 cache allocation AUTO, BSP Only or All Cores? Try them all, I prefer BSP Only when unlocking the chip for the first time, after that I use All Cores...

Did you try raising voltages or lowering nb multiplier?

I did raise CPU Vcore to 1.45..but i did not tried that with nb multi.

L3 cache Allocation was Auto.

Should I set BSP Only First and then enable the ACC Option??

BSP only disables the L3??

I wil try with an new CPU later today..:D

When I received my first CACYC AC 620 chip I was having trouble with bios post with one of am2+ Asrock mobos, back then there was no strong and acc modified bios available so much more tweaking was required (X3 720, X4 810 etc)...

So my procedure:

Power on -> enter bios -> L3 cache allocation -> BSP Only (first core gets whole L3 cache) -> save and exit -> enter bios -> ACC Auto -> save and exit

In this way bios post, if L3 cache allocation AUTO or All Cores -> no bios post, reset button required... Now with new bios versions most of Asrock mobos don't have that problems anymore but not all are fixed...

But if your boot guard doesn't reset bios to defaults something is defective for sure... With lowering nb multi you lower L3 cache frequency, well, it is still better to have 6MB L3 cache operating at lets say 1600-1800 than no cache at all :) Or you can bump voltage from 1.17V up to 1.30V - 1.35V, if that doesn't help well your new chip is on his way :D

Thanks for the info man!!:D

I've done all theseee :p

Well..my new chip is on his way..:rofl:

@Cele03

I used to own one that can unlock 4th core and 6MB L3
http://valid.canardpc.com/show_oc.php?id=785919

but my friend borrowed my CPU for some bench and he killed it by accident :(
RMAed it back to dealer and the replacement can't unlock 4th core/6MB L3

i have this result i mean i try to unlock l3 cache but i cant

i thinks its a buged an fast cpu for gaming but i have 2 question

i cant push my corsair xms3 on 1600 cuz i get bsod and second , my chip can get l3 cache its i buy a msi mobo or gigabyte ?

my cpu batch on box its ADX435WFGIBOX

THANKS! and sorry for my bad english this its my first AMD build

The Batch code is on the actual chip itself.
