Phenom II x2 555 unlock - Page 6

post #51 of 58
IBT is actually pretty good, CPU and temp-wise. For everything else it's sort of a hit and miss.

I'd also suggest to stop using AMD Overdrive, it's a great tool to start learning how to overclock, but it's very bad for stability testing. With a bad overclock, I can pass AOD stability testing for hours at a time but fail Prime95/IBT/LinX in a matter of seconds.

If you fail IBT/LinX, lower your CPU clocks. Best way is to increase as high as you can from stock voltage and go up in voltage when you fail tests with your highest overclock. As others have mentioned, overclocking takes days or even weeks to finalize.

If everything else keeps failing, it's possible that your board is purposely using a faulty core when it unlocks. My buddy's Asus M4A79XTD Evo would always end up using his Core1 (faulty core) when he tried to unlock, and he could not disable it, so he could only use a dual core, while I could get it to work as a tri-core(Core1 disabled) on my MSI 790FX-GD70.
Course I'm using a BIOS OC, was just using amd overdrive as a stability test and temperature meter. This sadly is definately the case as if I lock all core except the un-lockable core 0 it is still defective. I wonder if upgrading BIOS would fix this.

Prime95 on worker one went stable for 4 hours, worker two stopped due to hardware failure at 4.3 ghz, will try again.

4.2 Ghz runs stable, 4.3 will eventually as well... Just needs a bit more fiddling

Grats on your 4.2ghz!

Yeah.. some Asus boards don't allow users to disable Core0 and/or Core1. I know that my friend had a BIOS version that would force him to use Core0 and Core1.

When I upgraded it to a later version that could disable his faulty Core1, it would let me boot with Core0 and Core2 activated or with Core0 and Core3. But once I had Core0, Core2, and Core3 activated, it would not boot, even if it did work on my board (stable too).

Yeah that same ASUS bug is in most of their BIOSes, really annoying if you know a CPU can unlock with core 1 disabled (or 2nd core as its called in alot of ASUS bioses) but the motherboard won't POST with it, for no reason.

If you want to unlock your CPU to a quad this should be done 1st before any overclocking inorder to validate that the cores are good.

go back down to stock speeds,

unlock the cores and Prime/Linx test for a few hours minimum,

then you can begin overclocking,

bear in mind you will be unlikely to hit 4 -4.2 ghz as a quad but 3.8 should be within reach. I built my Sig rig before christmas and am still working on my overclock now, waiting on my new Kuhler coming to get my temps in check before going any further with it

hope this helps

I somehow feel like you didn't bother reading the other replies, as what you've said has already been posted, but good advice nonetheless.
