AMD's Athlon 64 X2 5000+ Black Edition

End Of The Line At 3.40 GHz

We continued to increase the core voltage, first to 1.475 V and then to 1.500 V.

We were able to boot the system at 3.40 GHz without a problem, and even run several benchmarks, but not all of them. At this speed, Prime95 - our standard when it comes to stability tests - would not complete its test run without errors.

If you use a water-cooling system, you may be able to reach higher frequencies still, since the core temperature is much lower than using normal air-cooling, giving the core a little more overclocking headroom.

When we tried increasing the clock speed beyond 3.4 GHz, the system crashed immediately.

Since the front-side bus is not overclocked, the chipset does not require additional cooling.

As the final entry in our overclocking logbook, we present you with a table detailing the combinations of multipliers, voltages and memory speeds of our overclocking tests with the 5000+ Black Edition:

Overclocking Logbook
Frequency Voltage Memory Multiplier
2.60 GHz Standard DDR2-743 13x
3.10 GHz Standard DDR2-775 15.5x
3.20 GHz 1.400 V DDR2-800 16x|
3.30 GHz 1.450 V DDR2-733 16.5x
3.40 GHz > 1.475 V DDR2-755 17x

    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?

    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

    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

    And to think i passed this one up for a 5200+, for some god awful reasoning at the time. Ah, the good old days!
