AMD's Athlon 64 X2 5000+ Black Edition


The "Black Edition" of AMD's Athlon 64 X2 5000+ features an unlocked multiplier. Unlike the first Black Edition model, the 90nm 6400+, the new processor is produced on a 65 nm process. As a result, it only draws about half as much power as the 6400+, and offers enormous overclocking potential. Pushed to its limit, this processor is faster than an Athlon X2 6000+ or Intel's Core 2 Duo E6550. Among today's CPUs, this $130 processor is unique in that its performance can be increased without having to raise either the FSB or the memory frequency, making it a safe choice for any AM2 board.

Let's get right to it: If you're considering buying the 5000+ Black Edition, chances are that you intend to overclock it - and we mean really overclock it. If that's not your cup of tea, you can safely choose the 5000+ EE, which comes with a locked multiplier and costs a bit less. Therefore, this article focuses on the processor's performance and behavior in its overclocked state, comparing it to other current processors from AMD and Intel.

Of course there's nothing to keep you from overclocking the Intel processors included for comparison here as well. However, within this article we are considering the 5000+ Black Edition primarily as a CPU upgrade for people with existing AM2 systems, meaning that Intel processors are not an option.

Athlon 64 X2 5000+ Black Edition: Front with heat spreader and model number

Back of the Black Edition: The bottom of the processor with its pins.

What makes the 5000+ Black Edition especially interesting, aside from the unlocked multiplier, is that it uses the newly introduced G2 stepping. This refined processor stepping allows the processor to stay stable at higher clock speeds without requiring an increase in core voltage. The obvious benefit is that you can put an inexpensive overclocked AMD processor into your PC, and the CPU fan won't need to run at speeds that make it sound like a turbine. Thus, thanks to the low thermal power dissipation, you don't need to spend extra money on a complex cooling solution.

    what kind of cooling system is needed to overclock to 3.1 Ghz? I'm buying a barebones kit with this CPU but no heatsink/fan.
  • Cursedeyes
    this article is very helpful, but my bios lets me increase the cpu voltage in increments of 5 mV up to 600mV . so how much to i out it up in order to equal 1.450 V?
  • falchard
    1000 milliVolts = 1 volt

    1450mV is my guess.
  • what heatsink fan was used for this? stock X2?
  • Koshi
    This article was helpful in making my decision to buy this processor, but I have a problem when overclocking it (first time overclocking). My pheonix award bios on my m2n sli board wont let me increase the cpu voltage past 1.325, and I want to know if there's anyway I can increase it. I can only get to 14.5x multiplier at this voltage.
  • Hi,

    Great article. I am new to OC, and have the 5000+ Black Edition and I am running it in an Asus M2N-SLI with a Zerotherm Butterfly CPU cooler. CPU according to HWMonitor, Core 0 is running at about 18C and Core 2 is at about 19 so heat shouldn't be a problem. Memory currently is Patriot 1GB PC2 5300 667mhz but in a couple days I will be adding 4 GB of OCZ SLI Ready Edition Dual Channel DDR2 800 Mhz . My question, is will the 667 Patriot memory that I currently have work if I overclock to 3.0, and would the OCZ 800 be adequate to OC to 3.2 ?

    Second, I've not done this before, from what I can gather here I can just change the multiplier in BIOS without messing with voltages if I don't go beyond 3.1 which would be achived by using a 15.5 multiplier.

    Thanks for the information here and any tips...

    I have this CPU , been very happy with it so far. I have it at 3.2ghz running smoothly. I put a gigabyte GIGABYTE GH-PDU22-SC EVR Sleeve CPU Cooler only cost 23.00 has my cpu at 32c idle
  • Skiscola
    I can only get mine to a 14.5 multiplier I have a M2N-SLI Deluxe MOBO,CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory X2 for 4 GB, Thermaltake CL-P0075 80mm 2 Ball CPU Cooling Fan/Heatsink. How can i get it higher without it crashing
  • Darkerson
    And to think i passed this one up for a 5200+, for some god awful reasoning at the time. Ah, the good old days!
