It will do 80MB/s, so it's fast enough for a dual Pentium Pro! (I'm going to have to fit it out with 5ns EDO RAM though!!!)

Check your edo voltage.

40/50ns chips are often 3.3v not standard 5v but some can be 5v tolerant. Though not all

I'll definitely take this into account when ordering RAM for this card!

Honestly it may be easier to just set the fpm jumper and stick a 60ns 32 mb fpm in it… or…edo in it. I don’t recall how but there is a way to turn edo into fpm. Pulling a pin high or low I think.

I’m gonna guess that they probably didn’t route the address lines for it, but max ram that will fit in the slot is a 40ns 3.3v 128mb edo. Not saying it is compatible, just that that’s as fast as simms that I have seen got.

I see no mention of voltage in that manual. Making me think that it is probably 5v

Get out your volt meter and check I’d say.

Continuity between simm 5v pin and pci 5v pin. See what you have.

It's currently fitted with a 128MB 60ns FPM ECC SIMM. (I'll run it with this initially and then upgrade it to 50ns EDO and compare the performance difference.)

According to the review, slotting an EDO SIMM increases the cards performance by as much as 20%! (That's a pretty tangible performance difference!!!)

That’s wild. I’m interested to see if it holds up to real world tests.

Just a question, will a socket 370 cooler fit a socket 8?

This year I'm going to go ahead with this build:

The InWin X-Frame 2 has the perfect number of slot positions to properly accommodate this motherboard, but as the board has an AT form factor, the standard tapped standoff holes are in the wrong positions to accommodate this board. Rather than drill and tap new holes into this expensive motherboard tray, for now I plan to make use of period correct plastic standoffs, which I'll neatly epoxy into position, as the double-sided tape that they come fitted with won't offer a permanent solution.

I have a nice 1.22MB floppy drive as well as a SCSI DVD-ROM, both with black bezels, which I'll slot into the lower drive bays. (Seeing that it's a dual Pentium Pro, it will definitely need a floppy drive!)

I really hope that once I've flashed the BIOS to the latest revision , the Voodoo5 5500 PCI will fire up in this system!

The socket 7 heatsink is adequate to cool a ppro, provided it contacts the whole gold top.

The heatsink clip is incompatible.

Thanks for the reply! 😀

I've already decided to make use of the standard heatsinks that these CPU's were released with!

Love to see a SCSI Ultra 320 drive in action as well as the SCSI card. I do notice yours is an adapted 80pin interface though. (my ST336607LW is the more classy 68pin.)

The drive used in initial testing won’t be used in the build!

In the next two weeks I’m purchasing two 68-pin 73GB 15K RPM Fujitsu SCSI drives which I’ll run in RAID 0 as the system disk.

300/600 gb drives are going to be even faster than 73's

They are harder to find though.

Not in any meaningful way, but if the plan is to swing your dick around...

I agree, but I was able to get two of these drives for a very good price:

And these two CPU coolers: (NOS)

And 512MB (4x128MB) of this RAM: (Because of the PCI slot arrangement on this board, I'll only be able to slot 4 SIMMS and have everything fit!)

On this base board, PCI slots 4 and 5 share the same IRQ and the Media-Bus card card needs to go into slot 5, so I'm going to have to slot the SCSI RAID card into slot 2 (This is a very long card so it will block two of the RAM slots unfortunately!)

I'm probably going to slot a USB 2 card into slot 3.

And the Oxygen 202 will be replaced by the Voodoo5 5500 PCI if I can get the latest BIOS revision to fire it up:

if you need more PCI slots, you can always find the big brother to that board...

That's quite a base board you have there!!! 😀

I'm sure that those are pretty much unobtainium at this point!

You'd need a very special chassis to house one of those! Especially if you want to make use of both the ISA and PCI slots! (The InWin X-Frame 2 won't cut it for one of those!)

I know I’m being captain obvious, but make sure you have decent fans blowing over those 15Ks. They usually run very warm to outright hot depending on usage. It’s a commonly overlooked thermal issue with SCSI based desktop and home server builds.

Thanks for the input! 😀

They do tend to get pretty warm indeed!

I intend mounting them in these positions on the back-side of the X-Frame 2: (The drives will be exposed to the open air, but I will setup a fan arrangement if necessary.)

The pictures shown, show the internals of the actual drives I've ordered.

I intend to orientate the X-Frame 2 vertically on its stand

I'm considering this RAM for this card! (I'll only make the purchase once the machine is fully assembled and running)

This is the only 50NS 128MB SIMM I could find and my only question is whether SIMM's for the Amiga Blizzard 1230IV 1230 IV are standard 72-pin memory? (This is obviously not ECC emory)

My card is currently fitted with a 60ns 128MB ECC FPM SIMM. Would it be worth swapping this out for a 50ns 128MB non-ECC EDO SIMM?

nope.

the scsi drives you have are too fast, that cache will never get any use.

its 110% dick waving.
