DS10 Workstations The 600 MHz system is also offered as a workstation and is called the AlphaStation DS10. The sophisticated branch prediction in the 21264 coupled with the speculative and dynamic execution extracts the most instruction parallelism from applications. For more information about the chip, see Alpha 21264 Features Out-of-order instruction execution Large (64 Kbyte) on-chip data and instruction caches. Architecture The traditional bus interconnect has been replaced by a switch- based interconnect system. With a bus design, the processors, memory, and I/O modules share the bus.

As the number of bus users increases, the transactions interfere with one another, increasing latency and decreasing aggregate bandwidth. System Board The interconnect switch is implemented on the system board by the chipset consisting of one C-chip, one P-chip, and two D-chips.

The chipset provides the data and address path between the CPU, memory, and the I/O subsystem. The CPU installed on the system board is the Alpha 21264A (600 MHz). Memory Memory throughput is maximized by the following features: 128-bit wide memory data bus Very low memory latency (120 ns) and high bandwidth with 12 ns clock ECC memory The switch interconnect can move a large amount of data over the memory data bus. System I/O The industry-standard PCI bus is the number one choice for high-performance I/O options, such as disk storage and high- performance video applications. The PCI bus implementation has the following characteristics: Fully compliant with the PCI Version 2.1 Specification Operates at 31 MHz, delivering a peak bandwidth of 250 Mbytes/sec. It functions as a Halt button with Tru64 UNIX and OpenVMS. Storage The DS10 comes with either an internal storage cage or a front access storage cage.

The internal storage cage systems have five storage/media bays. In addition to the floppy and CD- ROM, the other three storage bays can support three internal 3.5”. Error Reporting Compaq Analyze, a diagnostic service tool used to determine the cause of hardware failures, is installed with the operating systems. It provides automatic background analysis, as it constantly views and reads the error log file.

Memory Channel interconnect bus between disks and systems. OpenVMS cluster systems use the CI, SCSI, Ethernet, FDDI, and Memory Channel as the interconnect between disks and the system. The primary means of clustering AlphaServer DS10 systems depends on the operating system. Ethernet, OpenVMS CI clusters, OpenVMS only. Service and Support Compaq provides a comprehensive set of services that range from migration, consulting, and training, to direct support of Alpha systems, software, and applications.

:Hello DEC experts,::I have emailed the CPU people 'CPU people'? I'm not sure I want to know.:-):with no reply and was wondering what experiences:other users have had with upgrading the Alpha 255 workstation.:The manual refers to an upgrade path to 300MHz (from 233MHz).:Is this just a CPU swap, or a complete board swap. Donno, but - unless you are planning on trying to roll your own version of the upgrade - does it really matter? (I.think. the kit consists of various parts, probably including a new SROM, and installation documentation - and not a new CPU board.) Check with for the pricing and availability, as well as a brief description - this assumes you already have the upgrade part number of course.:Also, is this machine upgradeable to faster than 300MHz, via CPU replacement. There is no AlphaStation 255 system at faster than 300 MHz. 300 MHz pretty much 'tops out' the EV4-derived (21064-class) microprocessors.

Beyond that clock speed, one tends to sees EV5 and its derivatives (21164-class). pure personal opinion - note to those folks not contributing spam - there is no ZZ in my address. :with no reply and was wondering what experiences :other users have had with upgrading the Alpha 255 workstation. :The manual refers to an upgrade path to 300MHz (from 233MHz). :Is this just a CPU swap, or a complete board swap.

the kit consists of various parts, probably including a new SROM, and installation documentation - and not a new CPU board.) I have an ALPHAstation 255/233. The hardware documentation mentions the possibility of upgrading to 300 MHz, which involves at most swapping the CPU and a few related bits, NOT the motherboard.

Of course, you can buy a 255/300 as well. There is also mention of the possibility of FUTURE in-cabinet upgrades involving probably a motherboard swap. The box itself looks very similar to an ALPHAstation 500, which is a 21164, not a 21064A. Could, in principle, and if so, will it be offered/supported and if not what is the future upgrade mentioned, one upgrade a 255 to a 500 by swapping the motherboard? That is, keep the monitor, keyboard, graphic card, memory, disks and other SCSI devices, just replacing the motherboard (and of course the CPU)??????

I'm just wondering about buying several hundred MB of RAM; if I could use them later (either in an upgraded 255 or in a 500) I would feel better about buying so much memory. Does anyone know if there are 128 MB SIMMs available for the 255 yet? That would allow for 1GB of RAM in the machine. Nuffield Radio Astronomy Laboratories Tel. +44 1477 571 321 (ext.

I do not know of any upgrade - beyond AlphaStation 255/300 - that has been offered for the AlphaStation 255 series.

Alphastation 200

There are internal differences in the enclosures - if there were a swap, I'd expect to need some extra pieces and parts beyond just the new motherboard. (Unfortunately, it's usually easier to swap the whole box.):I'm just wondering about buying several hundred MB of RAM; if I could:use them later (either in an upgraded 255 or in a 500) I would feel:better about buying so much memory. The SIMMs used in the AlphaStation 255 will typically operate in other SIMM-based memory systems - though not all SIMMs for other SIMM-based systems will operate in the AlphaStation 255. Eight standard 60ns (or 70ns) 36bit 72pin SIMM slots, with SIMMs added (only) in groups of four.

Locally, PCs tend to end up with the SIMM hand-me-downs. Faster Alpha systems may or may not accept these SIMMs - newer systems might require (faster) SIMMs, such as EDO DRAMs.:Does anyone know if there are 128 MB SIMMs available for the 255 yet?:That would allow for 1GB of RAM in the machine. The maximum supported memory configuration is 512 MB, though the design can apparently support up to 1 GB.

The largest currently available SIMMset for the AlphaStation 255 system is the MSP01-BD for 256 MB (4x64MB). The MSP01-FE, for the AlphaStation 500, is the only 512 MB (4x128MB) SIMMset in the MSP01 memory series.

I was wondering if anyone has upgraded from Windows NT 3.51 to Windows NT 4.0 on the AlphaStation 255/300. I seem to have quite a problem with video drivers (missing DISPLAYDRIVER.DLL error). I seem to have overcome this problem when installing 3.51 by using the Custom installation method and a hardware support floppy from DEC, but for the 4.0 upgrade all i have is the MSDN Windows NT for alpha distribution.
