4GB SDRAM on Pentium III 500 (Dual CPU), Compaq Proliant 3000 Memory Upgrade

4GB SDRAM on Pentium III 500 (Dual CPU), Compaq Proliant 3000 Memory Upgrade

I bought this machine untested with no warrenty for only 25 euro. So I gonna restore it to full working order! Lets upgrade and see if the system supports 4GB memory! Dual Pentium III with 4GB memory is awesome!

Me when I read the title:
Pentium 3: 🤩
DUAL CPU: 😳
4GB SDRAM: 🤯

[guywhoknows]

The 4Gb limit is "standard" for back then and 32bit addresses, some Bios offer a " memory hole" or "remap" for big memory installs which can be found in the bios.
The limit comes from the Controllers as they were only 32Bit, there was "extended" which as you can see what that extension is.

did you check 1 1gb stick? in the second CPU? if the other has none it wont boot... The systems with 1 CPU the other has a "terminator" installed if its not operating. Ill teardown my 580 next week and the 360 as they are interesting.... Ill Pop a photo on the FB group ... shortly
The one thing I miss from some of these is the PCIX (PCI 133 extended)

Windows 2000 Advanced Server can use up to 8GB via PAE (Yes, on a 32bit system)

[robertsteinman]

Hitting a 3.5GB limit indicates 32-bit limitation, I think this is why OS' got 36-bit (been a while don't hate) AKA PAE support to come around this

It's total nostalgia trip this, i love it 😊

Grate video Victor! From what I can see MOST 32bit x86 systems tend to leave a memory hole above 3.5Gb so really not surprised, it sees the ram but ignores it. Check if BIOS supports "memory remapping" and enable it, might allow for windows to see all the 4Gb. 32bit Windows will only allow 2Gb per program at the most anyways if I recall and with 36bit extensions it will segment the memory in 4Gb chunks for a max of 16 if I recall.

I do wounder if it has dual PCI controllers, Sisoft Sandra can usually show the PCI/AGP controllers if Ir recall, 2000 or the 2003 version should work under W2K.

Victor Bart you can never have too many raid controllers only not enough space. Victor Bart mad man extraordinaire love your stuff man.

[MrJmannik]

You can only address 4gb of memory total with the 32bit chipset. The reason you are not able to see the full ram is because other devices (raid controller, video controller etc.) need memory address space as well

So much memory! my pentium 166 in 1999 only had 16mb!

[scifreaks]

Nice vid, not sure about this machine, but i think 2 1GB sticks are needed. or take one CPU out to test the 1gb ram module. Slot 5 first then slot 1 is the recommended order

A Home Depot I worked at 15 years ago had the hp proliant dual pentium 3 servers. They were extremely reliable. The huge apc galaxy (style can’t remember the exact model it was beige and grey) ups took out the data room when it went up in flames. That is what it took to kill these old hp-ux machines.

[dbozan]

The fact that the machine detects 4GB but wont use it all is normal for 32-bit machines. Check out the Wiki article called "3 GB barrier" to learn more. It's possible to access the additional ram with PAE, but it's not worth the downsides in win2k/xp. Checking if it works with a Linux Live CD might make for a fun quick video though.

[chrislowe]

also both CPU's require ram to post. Can't just install 1 ram stick in 1 CPU u MUST install 1 ram for each CPU. Also flash the BIOS to latest

[timmynatorX]

Hey, don't blame me for buying awsome stuff!
=)

[Leviathan]

Victor, in theory you can have as many points slots as you want, as they all share the same bus. I would hate to see what would happen if you filled all them though, as I don't think there are enough IRQs for all the resources required.

[breestandard]

The Compaq ML330 G2 with Dual Pentium III-s 1.4ghz. Would only see 3.6GB out of the 4 1GB sticks, all were Compaq spares.

[framebuffer.]

back in 2000 my hard disk was just a little more than the RAM on this maxed out configuration O.O
does anyone have info about the total cost of 8x512MB ECC in 2000? I'm guessing something between $7.500 and $10.000, but could be much more

[mccrh]

Lolz, me and my buddies made a drinking game around every time the word SCSI, is said on this guy's vids ;) Dam we be drink :/

[bundesautobahn]

4 GB would be complete overkill on a Pentium II under regular circumstances, especially with the 32 bit limits. I'll be glad if I can find parts for a Win 98 machine and deck it out to 512 MB, 1 GB at most. But 4 GB is completely justified I'd say for a server.

[delorean]

I wonder if a BIOS/firmware update would add more support for more ram or newer cpus?
