Glad to help, make sure you keep an eye on temps though. The extra cpu-nb adds heat to the cpu. I know it's Winter for you down under but I'm sure it's still fairly warm.

Yeah it is fairly cold here at the moment, down to -3c at night :eek: Doesn't seem to have added any extra temps running nb @ 2600, but I'll keep an eye on it :up:Quote:

Not to sure, where are you? :)Quote:

The advantage to nb clocks is that your L3 cache runs at this speed. Better overall performance since the cpu cores aren't waiting around as long for data I'd assume. I'm in Massachusetts, USA elvation about 30m above sea level. I'd heard the average temp in Australia during the winter was about 55F(13C).
Hmm sweet, I'm going to see how running high nb affects 3d06 scores :)Quote:

Higher NB results in more memory bandwidth. Test with everest and you'll see the difference with each tweak.
Didn't take a note of my stepping, and I cbs taking off my heatsink atm. I'll repost when I do though. Was an easy unlock, only had to turn on ACC. Stable on ~13h P95.

Haven't gotten around to overclocking yet though.
anyone had try unlock proc 550 BE with mobo intergrated 780G Ultra chipset?
Pretty sure you can't with a 780G, since you need a SB750 or SB710 southbridge. I started off with a GA-MA780G-UD3H, and I changed it for my current board, so I could try unlocking my CPU.
What is the max safe voltage for these chips 24/7? Right now I'm running 3.9ghz @ 1.5v and 4 cores (under load it drops to 1.488v.) Prime95 stable for over 5 hours, which is good enough for me.

>24h stable on P95. I'll get to overclocking mine eventually.
Success!

Board Asus CrossHire III, last BIOS 0403 ... look at new menu Unleashed Mode ...
But, my two cores are very bad, i cannot to OC them above 3,4 GHz ... at any voltage.

Wohoho look who is here,my old mate Cele303,you have the same batch like me :)
Kaydat's right for the most part. Although board companies are starting to put out 780G boards with a 710 southbridge.Quote:

Actually yes, you're right. Best bet is to simply check if your mobo has a 750/710 southbridge or a 700 southbridge, rather than the northbridge designation.Quote:

Which one should I keep? Neither of the steppings seems very successfull unlocking :shrug:

This might of been asked before.
But how does one check the temps? Real temp can't even be open while Core Temp have a ? on it :(

I purchased the CPU about a month ago and its a 0919EPMW Stepping and had 3.8Ghz in my old Asus M3A32-MVP DELUXE/WIFI-AP Motherboard as a dully.
On the Gigabyte however Its now a SUCCESSFULLY UNLOCKED QUAD :D
http://www.michaelscomputers.co.uk/p...IIB50stock.jpg
I've been playing ever since and managed to get 3.6GHz nice and stable:
http://www.michaelscomputers.co.uk/p...IB503.6GHz.jpg
To say I'm happy would be an understatement :) I'm having some issues with getting it to 3.7GHz as a Quad with Blue Screens & Reboots but still playing with bios settings! I'm more than happy with 3.6GHz but playing around is fun :) . The load temps are about 55deg running as a Quad 3.6GHz also, they do go up fairly rapidly when I use more volts though.
So please add me to the list:
0919EPMW - gamesaregood - GA-MA790X-UD4P - F5 - SUCCESS - :D
Im glad to see you flashed to the F5:up:
Lots of people that could not unlock these chips were using F2 or F4 Bios which is by all means buggy as hell.
Even when i first installed my 550 i flashed to F5a beta before even testing the Stock F2/F4 bioses.
Once i saw people were having problems tweaking the Bioses i flashed to the Older ones and experianced thier Problems.
To Date the F5 is the Most reliable Bios for ALL AMD chips on UD4P.
Ive tested and played with all Volt settings with a 9950/720/1640/550/6000+ cpu's. and the F5 handles em all.
So if anyone is trying to UNLOCK 550's please use the Most recent Bios for Your Mobo.
It will save you AMDheartheadache , if you update teh Bios from the Get go:D
