The AMD Athlon64 Socket 939 platform was established on June 1, 2004 to much fanfare. AMD enthusiasts were keen to acquire their hands on double channel Atlnon64 CPU boards and CPU's that did not require registered ram. The significant of utilizing regular unbuffered ram was twofold. One, buffered or registered ram endures a very slight function penalty equated to the unbuffered ram. Two, Unbuffered rams are affordable with much excellent selection on high function examples. Which means for many, the chances to utilize low latency rams with arguably the quickest platforms that were arriving onto market, the excellent of both worlds so to speak.
Total Hyper carriage bus acceleration was added from 800mhz to 1000mhz and estimates were that Socket 939 Athlon FX53 would accept a good timeabout 5-10% achievement advantage over FX53 chips on Socket 940 platform. Additionally, lower priced CPU’s like the 3500+ and the 3800+ @ were to be included in the Socket 939 lineup, to accompany the top of the band FX alternation CPUs who were priced amid each, bringing bi fold approach Athlon64 into the amount ambit of some who could not accept contrarily afforded the belvedere upgrade.
Reality admitting reared its animal head, while the 939 belvedere was fast and absolutely faster than Socket 940 systems at banal settings, there were about few choices in mainboards, and best if not all had their quirks and bugs
that inhibited addition from hitting aerial bus overclocks to accompany alternating the abundant college levels of achievement we desired.
To clarify, abounding boards while claiming to be flagship/enthusiasts boards offered actual poor voltage tweaking options. Appearance that were declared to be activity at barrage were either not implemented correctly, or due to design, aloof absent or broken. I accredit mainly to the VIA’s KT800Pro chipset and the AGP/PCI lock that was accustomed to be one of the capital appearance of this chipset, forth with 1000mhz Hyper carriage support.
NVIDIA’s NF3 Ultra chip set for S939 was abnormally absent from the bazaar until mid July, and was again initially alone accessible on the actual actual big-ticket Gigabyte K8NSNXP-939 lath bartering. This approved to attenuate the bewildered to an ad measurement and it was about two months afore we begin Socket 939 setups starting to accomplish their way up the benchmarking ranks for awful overclocked PC's.
Socket 940 may accept been hardly slower alarm for clock, but it was able-bodied accustomed and top benchmarking wizards could assignment their abracadabra with about affluence on the earlier platforms, but could not able the nut on the 939 setups appropriate away. Boards were the capital obstacle, added specifically, the disability to calibration aerial HTT bus forth with aerial anamnesis speeds. It seems axiomatic admitting criterion array that the Athlon64 best enjoys actual aerial HTT speeds, so it's acute that aerial HTT was accomplished at a bigger 1:1 anamnesis interface with bound latencies.
