looks like the unlock chance is pretty good... i wonder if its my mb which wont allow me to raise my clock to 3.6ghz and more or if its my chips limit....

As the 720BE's are 955's that fail AMD's stability testing, its very possible that its your 4th core.

well even with 3cores i cant get 3.6ghz stable, so im pretty sure it has nothing to do with the 4th core

Fair enough, most lightly your chip then, i dont know of anyone else complaining of bad overclocks with the same board. If it makes it better, i cant get 3.6 stable any more, even with 1.52v.

Atleast this overclocks much better than my 720BE, and every bench is better with this one. Game's work around 10-20% faster fps than 720BE with same clocks, that's lot more than i expected!

So, it's your call, you can erase me from the list or let me be, atleast 720BE was most experimental CPU that i ever owned!

Uhm! thanks for stopping by, lol!
what games do you have that are running 10-20% faster? did you do a complete upgrade or just the cpu drop in? Cause i have MANY game that i have tested 3 vs 4 and I dont get nowhere near that! As a matter of fact I sometimes get better performance (~1%) running only 3 at the same speed as 4, I think its because of higher cache per core that 3 cores offer. My system is in the sig, and i have tested, test, tested everyway possible. There are games that benefit from the 4th core, as we all know them, but all the others arent effect at all! even GTA4 is only 3 to 4 for fps different running 3 to 4 cores with all settings maxed out. thats at 50fps so maybe I could say its a 7% increase. But thats both running +3.6 ghz

how stable is it? did you stress any yet? let me know!
everyday we get some more unlocked

. good job, btw.

Kidding... I'm waiting on a motherboard to come by UPS then I'll have my own x3 720. I can't wait to see how it goes. I actually just jumped off the Intel wagon.

I decided to ditch my Pentium E5200 because I was just too damn intrigued by these new Phenom II chips I just couldn't resist.

Welcome aboard. and many other! What kinda motherboard and ram you gonna use? I am sure glad the phenom2s hit the market. AMD is finally worth talking about. For like 2 yrs I could never suggest an AMD system in a fresh build. But now, its hard to recommend intel, except I would tell someone to go the i920 over the phenom955, because the 955 is not scaling in the price performance ratio with the other phenom2s! I may get heat for it here, but the total cost of a brand new 955/ddr3 rig isnt far from the total of the i920, these past few weeks! But the 720, is like the ultimate deal. All the other phenom2s are really. I just think that small 200mhz advantage the 955 offers is not at all worth the $$$ they charge for it!

What BIOS version are you running? We have the same board. I'm on F5/F5a. You?

I don't do full 8h stressing anymore; I figure out that if it locks up after 30m of Linpack, it'll be completely stable with a small bump in the voltage. At 3.6Ghz, my CPU-NB was stable at 2.6Ghz @ 1.375v. At 3.7Ghz It just barely wasn't enough, so I went to 1.4v.
At 3.6Ghz I needed 1.470vcore for stability; it was OCCT stable several times for the 1h test and was stable OCCT-Linpack too.

So getting a stable 3.7Ghz @ 1.52vcore lines up perfectly with the +0.05v/100Mhz most people are reporting once they hit their max speed on stock voltage.

I've since been fine on 1024M wPrime, about 8 runs of Cinebench. Stability was _almost_ there at 1.5v but partway through 1024m wPrime it crashed. So the extra 0.2v was plenty to reach stability. I haven't locked up since; am confident it's stable.

scores: 14953 Cinebench 64bit
wprime 32m: http://www.wprime.net/?q=fview&id=3580
1024m: http://www.wprime.net/?q=fview&id=3579
3dMark06:http://service.futuremark.com/result...0&UID=23214591 (it's reporting CPU Ghz wrong...???)
3dMark Vantage: http://service.futuremark.com/home.a...&resultType=19

Who manages this/updates the list? Should I send him a PM? Or will he just look through all the stuff he hasn't seen yet and find what's new?

we dont have the same MB i have the one without the "P"

hmm why is your cpu score in 3d mark 06 so low? i got like 5157 cpu points at 3.4ghz o_O

There's mine at 3.79GHz lol..

What the heck is the difference?
