Phenom II 720 BE in Biostar TF560A2+

Amd Phenom ii x4 945 / 3 ghz processor

Specs: Windows XP Pro, Phenom II 720 BE
my son is looking at upgrading his CPU. He currently has an AMD Phenom II 720 3 core Black Edition processor.

I'm looking at putting his old 3 core CPU into a Biostar TF560 A2+ motherboard. This CPU is rated 95W 2800 MHz. Looking at the Biostart website,

the fastest Phenom 3 core cpu they have listed as compatible is the X3 8750+ HD8750WCJ3BGH which is 95W and runs at 2400 MHz. I'm wondering if I could put my son's Phenom II 720 into this board and just underclock it at 2400 MHz. As a more advanced processor it would also draw less than 95W. I also wonder if maybe the Phenom II is a later generation and wouldn't work in this board although It seems so based on this link

Where they had a Phenom II 920 CACVC AC 0849BPBW running in the TF560 A2+. I should mention this going into a very mission critical work PC so I wouldn't want to risk damaging the motherboard..

I'd be grateful for any thoughts.



ps for some reason, my browser won't stop putting manufacturer as Amd Phenom ii x4 945 / 3 ghz processor. I'm not sure why as I change it and this comes back! it is the Phenom II 720 BE in Biostar TF560A2+ that I'm interested in!

am3 cpu can work with am2+ board. U have to try the cpu (i assume u have ddr2 1066 ready). Phenom II x3 720 is still a good cpu, why upgrade it? I would advice u to buy cheap athlon cpu for biostar board.

Hi Kuwese

thanks for the response. Well, my son as a trueblood gamer so he's after something quicker for his birthday (as always!). As you say, the Phenom II 720 is a superb chip, gives similar performance for a price well below the 4 core. I think the world is thinks everything should be binary so hates 3!

I have some highly overclockable 800 MHz DDR2 memory I plan on using for now, maybe get some 1066 memory with my next visit to online shopping.

Currently this PC has a single core 3500 Athlon M2 CPU and I'd like to get something for it now that gets the best out of it while I still can, so this Phenom II 720 should be just what I need.

phenom II 720 u said yourself black edition, this chip can be overclocked easily (simply by changing cpu multiplier) eg. 200x14=2800mhz or 2.8ghz (200 reference clock, 14 cpu multiplier) simply by changing cpu mult to 16 now cpu is running @ 3.2ghz. Heka triple cores are based on deneb quad cores with one core disabled, this means phenom II X3 720BE is a quad core cpu but one core disabled.
As u mentioned your son is a trueblood gamer *he should focus more on v-card*

Hi Kuwese

He's overclocking his 720 to 3.2 Ghz. Interesting what you say about heka being based on deneb quad core with a core disabled. I notice the power consumption of the 3 core is about 3/4 of 4 core at 95w vs 125w. The 95w feature attracts me as that is the power of the Phenoms that are listed on the Biostar website, so I know I'll not be overloading the board.

Actually, just talking to him, he thinks maybe the price jump from the 720 to the next processor up is a bit high at the moment so maybe he'll hang on for a while. It is useful for me to know that the 720 is compatible with the TF520A2+ board though as sometime I want to get the best CPU I can for it before compatible products cease to be available in the shops and the 720 my son has seems to be a good upgrade route. Do you think so?

i think u need to test the cpu as soon as possible. The big advantage of am3 is support of ddr3. From single core to triple core (yeah it is a good upgrade).
95w,125w it's not a power consumption, it stand for TDP (thermal design power)
this should xplain better

It's pointless for your son to upgrade the CPU. If he has the right board (AMD with SB710 or SB750 w/ACC) & a little luck, he can unlock the 4th core on his X3.

From the follwing link: "I don’t recommend upgrading your CPU unless the potential replacement is at least three tiers higher. Otherwise, the upgrade is somewhat parallel and you may not notice a worthwhile difference in game performance."

There's a one tier difference between his X3 & the top X4:

Your board supports the 1st generation Phenom but not the Phenom II. That is shown clearly in the link you posted...why would you think differently?

Hi Jam

the third link I gave in my intro to the issue is a Phenom II working in this board. It seems Am3 processors are compatible with this AM2+ board..

Sorry, I didn't click on the 3rd link. I don't know why BIOSTAR wouldn't list that CPU on their support list though? Could be they just abandoned posting updates for that board due to it's age.
