Elmer,

Turbo- Cooler
800 mc/s Athlon with KryoTech radiator
Who wants to get its vehicle at any price faster, can try, to even tinker - or give it to the hands of professional Tuning specialists. The internal processor clock leaves itself well cooled around 20 up to over 30 per cent hinaufkitzeln. That is then the profession of cooling specialists such as KryoTech.
We could be supplied by KryoTechs German Distributor Pyramid computer a such Athlon 'Kuehlschrank ' named Octan Frio to the house. ' only ' aufgemotzt on 800 mc/s, but but at present also really available. Meanwhile KryoTech offers already 900 mc/s and wants on the Comdex the Octan Frio super G to present, the first commercial computer with 1 GHz clock.
The Tower has a under-screwed refrigerator and comes so altogether on approximately 30 kg lebendgewicht, which makes an unpacking from the cardboard a weld-rubbing job.
The refrigerator roars about one minute somewhat louder, until it achieved °-43 C, and remains then constantly on a strong, but still bearable noise level of 54 dbA (8.2 Sone), crosses thereby however clearly the max. quiescent level of 48, admissible for offices, dbA (workstation-furnished emission characteristic value measured according to DIN EN 27779). Additionally the combination uses plentifully energy (compressor 180 W and computer 150 to 160 Watts), so that it does not have a chance to correspond to the American EPA standard (30 W). Who lets the computer pass through as servers, thus annual consumption (without monitor) should not be surprised at almost 800 DM! By the way the system swallows still 7 W in the switched off status...
But who needs highest computing or play power, probably hardly attaches great importance to these attendant circumstances. To the scope of supply of the Octan Frio belongs besides a set of loudspeakers with strong Subwoofer, which over-sounds the sonore noise with appropriate plays loosely.
Overclocking
The inserted Athlon processor was specified of AMD as 600-MHz-Typ (with max. 70 °C case temperature) and from KryoTech to 800 mc/s (for -40 °C) changed over and the voltage somewhat increases. KryoTech occupies the validity of the procedure with diagrams, which show the temperature dependence of the different semiconductor technologies. Afterwards the admissible increase amounts to nevertheless in relation to 100 C 32 °per cent for the MCOcS TECHNOLOGY with °a junction temperature of -40 C. Something misleading is this representation, because the junction temperature is not at all equal to the case temperature. Even if one keeps directly the chip surface constant °-43 C, the barrier layer would be allowed to do at least 10, 20 and more degree more warmly (to leave unfortunately calculate, there AMD neither the max. junction temperature nor the thermal resistance of barrier layer to the surface did not specify itself more exact values).
The max. junction temperature might be situated however as with Pentium III and copilot by mine not with °100 C, but only between 80 and °90 C. Thus would be the permitted over clocking degrees probably rather with 25 about 30 per cent. Nevertheless, in our tests the Octan ran frio with the Athlon-600 over-clocked around 30 per cent troublefree and above all: racing fast. As if hardened let we one night long one that of bench mark of the SPEC Suite (fpppp) run, the Athlon with max. current consumption loaded. fpppp the architecture of the Athlons provokes outstanding out and operates many at the same time its Exekutionseinheiten, from which high performance and high current consumption result.
Otherwise the Octan Frio marketed by Pyramid offers the current Highend standard: Athlon board of MSI with 256 MByte PC100-RAM, Elsa Erazor x Grafikkarte with GeForce-256 and 32 MByte SyncRAM, Adaptec Ultra2wide-SCSI including IBM-Ultra2-LVD-SCSI-Platte (35 GByte) and Intel network card PRo/100+.
But one must berappen then also 12,250 DM. As wages signs impressing performance values, is it with plays or in scientific tasks. For office functions à la BABCo Suite is the Octan Frio however clear Overkill. Sysmark98-Werte of 300 and more are situated here already in the ' transcendental one '.
During AMDs 750er and (shortly) the 800er their L2-Cache for the time being only with 2/5 of the processor clock operate, drives it the KryoTech-800 as uebertakteter Athlon-600 like so far with the half processor clock, which brings in for it a few additional per cent points in the performance. With a SPECin95base of 34,5 the computer in the current High end workstation class on same level with alpha 21264-700 and HP 8500 strikes itself and leaves the fastest Intel representative copilot by mine 733 (32,8) clear behind itself. And SPECfp75base is situated with 24,2 (copilot by mine: 19.5) also not so badly, although hardly over the values of a Athlon-750 in the newest AMD fixed board with Irongate Chipsatz Rev. C6 (24,0). However the Octan was equipped frio only with PC100-Modulen with CAS Latency 3. With ACS-2-cModulen the SPEC values added still slightly: SPECint95base: 34.8 and SPECfp95base: 24,5. Intel by the way indicates the SPEC values for the copilot by mine for a new compiler version (Vtune 4,5) with Prefetch optimization, which results in more performance up to 25 per cent. We let against each other begin however both processors still with Kompilaten from Vtune 4,0. And the plays à la Quake and CO controls the 12-KMark-Bolide, as one from the diagrams seen can, sovereign, like probably it in this discipline of the 750er with the help of the new chip record revision C6 adds properly, occasionally outdated. *** TRANSLATION ENDS HERE ***
Mit der GeForce-Grafikkarte gab es allerdings hin und wieder Probleme; um die Vergleichbarkeit zu erhalten, haben wir aber eh alle Messungen mit TNT2 ausgeführt.
Fazit
Ohne Frage, die Technik mit der Tiefkühlung funktioniert und ist praktikabel. Sie bringt gut zwei Geschwindigkeitsgrade Vorsprung. Bei der derzeitigen Innovationsgeschwindigkeit sind das aber nur wenige Monate. Da muss man schon mit spitzem Bleistift nachrechnen, ob einem diese paar Monate ein paar Tausend Mark wert sind. Einfach aufrüsten, etwa auf 1 GHz, kann man auch nicht, denn dafür benötigt man stärkere Kompressoren (diejenigen des Super G haben doppelte Leistung). Und hoher Energieverbrauch, Lärm und spätere Entsorgungsprobleme sind auch nicht zu vernachlässigen. Aber für manche Profis, für die jede Sekunde Rechenzeit bares Geld bedeutet, und Yuppies, die immer die Nase vorn haben wollen, kann sich die Anschaffung dennoch lohnen. (as)
