Last week we brought you the
I published this information along with Intel's peculiar statement, saying that systems with Giga-Pentium III are not supposed to ship with Intel's fastest official platform and finally Intel's helpful and knowledgeable German PR-team was able to supply me with an OR840 BIOS that has no 'high speed lock'. Thus I was finally able to run Giga-Pentium III on an i840-platform as well.
Intel 840 or 'Carmel'
If you should not be too familiar with i840, I suggest you to read my article about this RDRAM-chipset by the name of '
- Code name 'Carmel', bigger and stronger brother of 'Camino' or i820
- Official workstation and entry-server chipset
- Designed for RDRAM (Rambus) support
- Two Rambus channels, resulting in double the memory bandwidth and half the latency (through interleaving) of i820
- Bandwidth 3.2 GB/s with PC800 RDRAM, 2 GB/s with PC600 RDRAM, no support of PC700 RDRAM
- Support of PC100 SDRAM with additional MTH-chip, i840 can support up to 4 MTHs vs. only 2 MTHs supported by i820
- Recently published bug with ECC SDRAM, leading the majority of Taiwanese motherboard makers to drop plans to build i840-motherboards
- AGP4x - support
- ATA66 - support
You can see that i840 is a lot more powerful than i820, but it requires at least two instead of only one RDRAM-modules, to populate each Rambus-channel. Intel's OR840-motherboard is a dual processor motherboard with integrated LAN and I guess you can imagine that it does not sport any overclocking features whatsoever.
