[Risk it?] Phenom II X2 5xx BE or Athlon II X3 4xx ? [click me]

post #1 of 9
Thread Starter 
My Situation
I am currently based in the UK, so no microcentre
My MAXED budget is £150, lower is better. Student.
I DO NOT intend to upgrade GPU.
JUST CPU, mobo, memory.

The Motherboard : £49.30
Pretty much decided fully.
SB710 and CrossfireX (x16/x4 but meh, 3870 CF)
ASROCK M3A770DE 770 Socket AM3 £49.30

The Dilema: CPU £50-60
AMD Athlon II X3 445 3.1 GHz £54.96
AMD Athlon II X4 630 Quad Core 2.8GHz £63.50fleabay...tested...no warranty
AMD Phenom II X2 555 Black Edition 3.2GHz £67.96
AMD Athlon II X3 455 3.3GHz £69.37
AMD Athlon II X4 640 3GHz £74.25
AMD Phenom II X2 560 Black Edition 3.3GHz £76.94

AMD! Quit flooding the low-end range with CPUs!

The RAM £20
For now. Gradual Upgrade to hopefully 8GB.
Corsair GENERIC 2GB DDR3 1333MHz

My thoughts
I know that the success rate of unlocking CPU cores is not 100%

AFAIK, the mobo I am looking at is not a great overclocker.
I am looking at GENERIC memory, not all that good stuff.


So, with these fairly un-overclockable components, which CPU should I choose? How far will the mobo and memory hold me dowm from OC'ing?


Looking at it from another view;
Is a greater cost of the BE CPUs that may unlock worth getting if I'm going to pair it with not so great mobo and memory?

Is a greater expenditure on memory and mobo justifiable for an increase in performance I may be able to juice with the CPUs I have listed here, esp. the BEs?


Finally, I am a student who doesn't really want his/her data and downloads to be riddled with corruptions (I've heard unstable unlocked cores can do this); my time means a lot to me considering I don't have much to spare.


I love my mechanical keyboard.

BIAS much lol? sig gives it away.

An explanation would be helpful. lol.

Could you point me to a % success rate for unlocking X3s?

I agree, grab the 445. Since you are not OCing and will most likely not be trying to go after more cores, get the chip that gives you the highest stock clock while still having more than 2 cores and being the least expensive to boot. With the saved money, see if you can eke out a 785 chipset board.
It's so little!

Thanks for the reply...but why would a 785 chipset mobo be beneficial?

I recommend that you buy a better motherboard, 4GB of decent RAM and Sempron 145 CPU.
You will be able to OC the CPU to at least 3.5GHz (3.8-3.9GHz is quite likely) and hopefully you will be able to unluck one more core.
Then when you can afford it (and if you feel that you need it) buy a 555/560/565BE CPU.

Edit: one more thing: Look for deals on "open box" motherboards, you can save plenty of money that way.

Go with the 445, when it unlocks it should remain at around 95W TDP like the Athlon II x4; whereas if you unlock the Phenom II x2, it'll have a 125W TDP. The mosfets on that board being a 4+1 are unacceptable and very risky for 125W or over TDP processors.

I'd go for the Athlon X3 445 seems the best compromise between cores/clocks and price.

Sorry DrSwizz but I aint taking such a risk! I could get stuck with a single core disaster lol. In the UK, we don't get these 'open box' mobo deals...the most you can save is £5....

Yeah, I never really considered stability. Now that you mention it I might just get a better motherboard. The motherboard I was looking at does support CPUs up to 140W though...but I see what you mean.

Thanks for the reassurance lol. I probably will go for the Athlon X3 445 then!
