Pattern of system from Pentium III 550E, used in testing:
The motherboard: Abit BE6-II (a chip set i440BX AGPset, processor Slot 1 plug , to 4 arrangements IDE UltraDMA/33 and 4 arrangements IDE UltraDMI/33/66 through HPT366, possibility of change of frequency of bus FSB and powers of a kernel and I/O).
The processor:
Intel of Pentium III 550E (kernel Coppermine, cache memory L2 — 256 Kbytes on frequency of the processor, the recommended frequency of the bus of the processor — 100 MHz, a kernel supply voltage — 1,65 In, Slot 1 plug , konstruktiv SECC2, in box, pack date 01/28/2000, version A13433-001, made in Malaysia, S-Spec — SL3V5).
Hard disk: IBM DPTA-372050 (20 Gbytes, 2 Mb of the cache memory, UltraDMA/66).
Dynamic storage: 128 Mb, PC100.
The videoadapter: Asus AGP-V3800 TV (video chip set TNT2, a video memory —32 Mb).
CD-ROM: ASUS CD-S400/A (40x).
OS: Windows 98 with the installed drivers of the controller of hard disks UDMA/66.
Exercisers: a package of tests WinBench 99 v1.1, namely CPUmark99 and FPU WinMark.
Dispersal
Installation of modes of dispersal was carried out in BIOS Setup at the expense of increase in frequency of the bus of the processor in SoftMenu III Setup. Power of a kernel of the processor on all frequencies — standard — 1,65.
The order of installation and choice of parametres illustrate fig. 1-2.
