Re: K6-3 and Cacheable Ram

If you plan to overclock your FSB, you might have improved stability if you disable the motherboard's cache, especially if maxing out the motherboard's memory.
Re: Anyone tried most powerful/upgraded 80386 system?
Posted on 2015-06-06, 08:38
I remember using the built-in EIDE port on my 486 in the mid-90's for web browsing and office tasks. I didn't think anything of HDD speed until I put in a SCSI controller. I recall the speed benefit feeling similar to when I upgraded from 8 MB of RAM to 32 MB. It was quite dramatic. Will an (or any …

There are IBM BL3 chips on PGA adapter boards which often work on generic 386 motherboards. I forget if it has 8 KB or 16 KB of L1 cache. Forum member Anonymous Coward has/had one running at 3x33 MHz. I suppose this could be classified as the fastest drop-in upgrade for a 386-class motherboard. …

matze79 - it is nice to see someone actually has time to invest in this. Your efforts are most appreciated. I have a few questions for you. 1) How is the tracking quality of the conversion? A handfull of companies have made these PS/2-to-serial protocal converters over the years, namely Raritan, …

The only other ALi-based 486 board I benchmarked had slowish results as well, but it was a PC Chips board. Those results were worse than yours.

In my tests, the K6-III-450 scored 20.4 in Quake II (software mode, not 3DNow! enhanced), while the PII-400 scored 23.4 fps (software mode). The resolution was 640x480. In my tests, 3DNow! demonstrated a 20% enhancement at 800x600 (GF2), and depended on the graphics card. The enhancement decreased …

I wrote the wrong numbers down for 3dmark99, even at 350MHz the P2 doesn't get those scores. I was writing notes down on paper over the course of a few days working on it during my lunch hour. The other numbers look more legit but maybe I should redo everything. 1839 3dmarks and 2330 CPU 3dmarks at …

Couldn't find any old reviews comparing both chips at the same speed(except for the 686 comparison on Vogons normalized to 133) Did you find the data contained within the Ultimate 686 Benchmark Comparison insufficient to fulfill your curiosity? I have included the raw data as well, not just the …
Re: Another 486 being built

The results seem a bit on the slow side compared to similar era SiS-496- and UMC-8881-based motherboards using an AMD DX4-120. I was wondering if Abit has some hidden latency or if that ALi chipset is generally slower.
Re: Why do some 486 motherboards have a keyboard bios chip?
Posted on 2015-05-14, 22:07
If the motherboard does not contain a discrete keyboard controller (KBC) chip, the KBC is integrated into the southbridge chipset. Ume Um8886BF chipsets contain the keyboard and PS/2 mouse controller integrated into them. I do not know what will happen if you attempt to plug in an 8042 KBC into an …
Re: Windows NT 4.0 on Pentium 133
Posted on 2015-05-14, 09:55
My preference for NT 4.0 is at least 64 MB of RAM. 128 MB+ for single tab web browsing. I find that NT4 runs almost as fast as Win95 provided that you double the amount of system memory (compared to your W95 standard). P133 on NT4 is good enough. Even a P90 is an acceptable lower limit in my opinion …

So it is just the RAM that is not on the fastest setting? The L2 cache is on the fastest setting?

Chinny22, were your cache and memory timings on the fastest possible settings when you posted that Speedsys screenshot?

I will ultimately test all the motherboards to determine which boards I can simply put into the recycle bin and to determine which CPUs are functional, however I still only plan on keeping 4 of the 16 Intel 845 boards. I will keep all RAM and CPUs though, as these require little storage volume. I …

Are there different PCI-X specifications for 64-bit/66-MHz slots? I thought the different specification came with differing speeds. I also ran the Matrox Parhelia PCI-X in two other systems as follows. IBM eServer 306m with a 3.0 GHz Pentium D. The result was a score of 603 . IBM eServer 336 with …

From my internet research, the Dell PowerEdge 750 contains a 66 MHz, 64-bit PCI-X slot. The Matrox Parhelia 256 PCI is a 66 MHz, 64-bit PCI-X card.
