Unlocked Phenom II 555 BE vs X4 945

[orija7]

would it be better to get a Phenom II X2 - 555 BE and unlock it rather than buying a Phenom II X4 945 or is the X4 945 significantly better in performance and worth the extra cost?

I have the 555 BE @ x4 3.6 it is slightly lower benchmark than the x4 965 @ same clock. I found out why they made this a x2, its the core 3/4, max 3.6 before losing stability. can over clock the other 3 higher, but dont see the point. did need to increase core V to 1.4V

PS took a while to find out which core was the problem. Prime 95 eventually picked it up with some fine tuning (without bsod).

My MB = Gigabyte 785G US3H (no problems with this one) Its cheap too, my upgrade without gpu was under AU $300

Hi There, Robotguts here, I bought a 555BE last week and put it in a GA890GPA-UD3h motherboard and couldn`t unlock any cores at all through the Bios-@not untill Bios upgrade F7b from revision F2, 5 bios upgrades and week later @ F7b they included the Core unlocker in the Bios,
I have it stable with all 4cores @4000 MHz Volts@1.66 Temps=41.

I`m very happy with this, and what ever anyone says ...it is a true Quad core. the buyers of the 965 and 955 Quads are realy spewing they paid so much, for a chip that does`nt eve Clock up as good. good luck with clocking. also a big part of being able to overclock higher is a good power supply and a good cpu cooler........
ME=corsair HX1000w, Prolimatech Meglyhalems cpu cooler,(as good as it gets on air)..food for thought. hope some of this may help.

1.66 volts is getting into dangerous territory though, isn't it?

That's what I was thinking....

-Biostar TA790GXB A2+

-Gigabyte 785 US2H

-Biostar TA 785GE 128m

Whcih one would you recommend among these three?

I recently snagged a Biostar TA880 GB+ Ver. 6.0 and yes! SUCCESS unlocking my new 550BE to quad core.

I thought 1.66V was instant death territory

An unlocked x2 555 aka x4 B55 does not compare to the x4 945, its actually a crippled x4 965 C3.

A ridiculously easy to overclock 555 BE running 4 cores with 6 megs of L3 cache @ 3.2 ghz stock speed on a brand new TA880GB+ Rev6.0 mainboard all for $94.00 somehow doesn't strike me as "crippled". People are having 80-90% success rates unlocking these bargain chips.

they are called "crippled" because when you buy the CPU it comes with 2 disabled cores. I was also able to unlock w/o any issues but that does not mean that its guaranteed to unlock. I recently purchased an x2 555 for my HTPC and it only has 3 fully working cores as the 4th is faulty.

The Gigabyte 785 US2H will take a Thuban.

The Biostar TA790GXB A2+ will not (don't think a 955 or 965 is supported either but the 945 is)

I have a 5770 HD..Phenom 555...3.2..I have not tried to overclock..I think I should...though Idk what to change the settings to exactly lol...my friend told me to go tinker some!

Any suggestions?

 

[Dr soggy]

Is there any reason for not trying to unlock these processors? I just put one in a friends CPU, and I would hate to ruin anything that isn't mine.

No such thing as future proof IMO. The latest sofware, the latest games these days are slower to catch up to the latest hardware. Why buy something like a quadcore now if you don't need it. It doesn't seem like the OP is into running a 60MB raw image through 5 Photoshop filters. Isn't it a better investment, a better value to pay for something you can use now? Again, he wrote in for advide on how to get more bang for the buck. He had a question about value now and you're talking about the future.

I aguree get the 555. and when you need a quad then you can unlock the other two cores. I have one and i use two cores most of the time and when i play games that are resorce hogs i will open the chip up and bam! crysis 2 runs perfict
