Pros: GREAT PROC!!! I would give it another egg if it was available. Instantly unlocked to a quad core and overclocked to 3.4 Ghz via Gigabyte MA-870A-UD3 (rev 2.0). This CPU was under half the price of a phenom ii x4 3.4 GHz. This Proc will OC further as I had it to 3.9 GHz but it quickly reached 85 deg C while running Prime95 so I scaled it back. I need a better CPU cooler as mine is from an older build that I paid $8 for in 2007 but this isn't the Procs fault.
Cons: Not really a con since it is outside of operating specs but if you unlock to a quad core, your individual core temps readings are disabled by the processor. Because individual core temps are disabled you have to use something that just gives you the overall temp of the CPU like Easy Tune by Gigabyte.
Overall Review: My specs for unlocking and OCing via Gigabyte MA-870-UD3 (rev 2.0) are:
NB Voltage Control 1.100V
CPU Voltage Control +0.100V (1.4500)
CPU Unlock Enabled
That simple and super stable. Ran Prime95 for 12 hours with no errors and CPU temp via Easy Tune was 65 deg C. As I said, this proc will OC further but my cheap cooler just can't keep up. For the price/performance this chip gives you I can't understand why anyone would go the intel route. I paid a total of $230 for the MB/CPU/RAM (2x2GB DDR3 1600). Was a hell of an upgrade from my Athlon 64 X2 5000+ for the price. I know they are phasing out this CPU so buy it while you can.
Pros: Inexpensive and unlocked to an X4 in seconds. It was surprisingly easy and all 4 cores are running very stable.
Cons: None so far
Overall Review: Newegg is the best
Pros: +Overclocks extremely well
+4 cores easily unlocked
+Much better future upgrade path vs Intel
Cons: -CPU is being discontinued in favor of the 555 BE and the new 550 (non-BE). Pick this up while you can.
-Found it for a much cheaper price after purchasing.
Overall Review: I'm currently running this bad boy at 3737 MHz with no stability issues whatsoever. I could go higher with a better PSU, but that upgrade will have to wait for awhile. I haven't messed around much with 4 core operation other than to say it runs stable at stock speed. Since I pretty much got this for gaming, 2 cores are sufficient. The most demanding games only peg this CPU at 70-80% with 2 cores enabled. And considering I'm only running at 9800 GT I'd say that's pretty darn good. I upgraded from a Opteron 180 dual core o/c to 2.6 (same vid card) and this is a night and day difference.
Pros: Everything is a pro with this CPU compared to my old one. I was using an Athlon 64 X2 3.1GHz that I have had for about 3 years now. The reason I replaced it was due to the fact it would constantly overheat and freeze my comp. It would hit 50C+ when simply watching a movie on my browser or some other simple task. Only solution I was able to come up with was plop my comp on a stand next to my air conditioner with the side off and monitor the temps using SpeedFan. UNTILL I got this CPU. Its absolutely amazing. Under full load and over-clocked to 3.5GHz it just barley reaches above 30C on air. It feels weird to not have to constantly stare at SpeedFan anymore... lol
Cons: Nothing, besides the fact my Biostar TF720 A2+ Mobo can't over-clock this beast more.
Overall Review: Newegg is amazing as always. Ordered it Saturday night and got it Tuesday afternoon.
Pros: I bought the oem model along with a new Asus M4A785TD-M EVO and a 4gb "starter kit" of ram. The board unlocked all four cores and that was about 30 minutes ago. The performance is unbelievable compared to my old Ath64 3400.
It wasn't too bad for what I did with it, but it staggered under virtualization and took along time to compile code. I haven't compiled anything yet, but I can tell it's going to be instantaneous. Everythig else is!
Overall Review: totally rocks, and I got 4 cores for the price of 2.
Ubuntu 10.04 reports 4 cores of the Phenom(tm) II X4 B50 variety.
Pros: Unlocked the 2 extra cores, stable in vista 64...gonna hit it with games soon as they are installed. Over clocked to 3.2ghz for now, will try further once cores are OK'd. FAST FAST FAST CPU! CHEAP PRICE! And its unlocked!
Cons: Not a ONE!
Overall Review: I upgraded from a 710 x3 2.6ghz to this one and bam! Moved past 3gz and with 4 cores! WOW! Get this bad boy and unlock the 2 extra cores! my gigabyte 790x did it for me!
Pros: unlocked with ease gigabyte mobo overclock to 3.75ghz
Cons: wish amd would have left temp monitor intact on cores
Pros: Plug and play! I currently have this Phenom 2 running at 3.72GHZ, strickly on FSB adjustment, multiplier still at 15.5.
Cons: Can't unlock the other 2 cores. But, since I bought it knowing that might happen, I can't dock an egg.(I haven't tried with upping the voltage, might try later on.)
