- CockbrandAround the turn of the millennium I had a Sony Vaio 505TX, which had the same chipset. My machine was running Linux, and I maxed it out to 128MB RAM.There was a kernel patch for this chipset back then, which treated all memory above the lower 64MB as a RAM disk, which could then be used as swap space.This prioritized the faster portion of RAM while still having very fast swapping.
- HerbManicIt is funny to see how these older machines perform at their higher end limits. I'm guessing the idea on this was that if you needed that much RAM, the sacrifice of L2 cache was a worth while trade off.It was only a few weeks ago that I found out the original BeBOX computers would switch off L2 cache when running in dual CPU mode. It was just a limitation of the memory controller. Again, the thinking of, if you need the extra compute over memory bus it would be a worth while trade off.
- conspReminds me a bit about installing one of my 128MB 72 pin SIMM modules in a 486, it has the same caching issues. Most board will not accept them anyway (I have both FP and Edo ones) but if you put a lower capacity one in the first slot they will happily boot and accept the full ram amount if all lanes are occupied (which is not a given on all 486 motherboards). Also remember to enable quick ram check or you will be getting more coffee.
- pipesGoogle says sdram in 1997 was 7 to 10 dollars per megabyte. So 384 would be 3840 not 40,000 am I missing something here?
- sidewndr46Does the language in this not make sense to anyone? Is it trying to say the the L2 cache provided by the chipset is not able to access memory past a specific address?
- bellowsgulchThis would have also still been true even roughly a decade later, during which time the industry was going through a transition from 32-bit computing to 64-bit, and large amounts of RAM read from BIOS in pre-UEFI systems were slower to boot the more memory you had!Imagine young would-become engineers at the time finding that adding that second stick to their laptop did in fact, not make their systems magically faster.
- Iflalhow funny is this, we used to spend weeks fitting assets into 4MB, and now we spend weeks trying to figure out why a 'Hello World' microservice is OOM-ing in a container with 2GB.We traded the 'Mo RAM' for 'Mo Layers,' and in the process, we lost the ability to reason about what the hardware is actually doing. Sanglard’s breakdowns are always a sobering cold shower for those of us pampered by modern GC and JITs
- MrBuddyCasinoMy 1997 mainboard had extensible tag-ram, if I remember correctly. Perhaps this is the issue?

- hsbauauvhabzbMany modern apps seem to cache based on total ram installed, and don’t seem to scale well to larger than normal systems. Chrome, I’m looking at you.
