Why are you looking for this card? Unless you want it for your collection, a GeForce2 GTS or Ultra or Ti offers much better performance and less trouble.

Re: PCI to PCI-EX adapter card questions
Posted on 2019-05-12, 06:31
Some cards are passive like on your photo. They only do voltage conversion and signal resynchronisation. They are less expensive and don't work very well. there re no passive cards, one bus is parallel, other serial I mean the conventional PCI and PCI Express are nearly the same from software point …

Some of these cards use a PCIe-to-PCI bridge chip. They are more expensive and more reliable in general. Some cards are passive like on your photo. They only do voltage conversion and signal resynchronisation. They are less expensive and don't work very well.

This is the beast. https://i.imgur.com/1VY3KFP.jpg It is basically an all-in-one PCI card with an ATI Rage II 4Mb video, dual channel Ultra2 SCSI controller (LSI 53C896) and Fast Ethernet network (Intel 82559). Everything sits behind an Intel branded DEC 21152 PCI-to-PCI bridge. However it isn't …
Re: Soldering an ISA Port to a Mainboard

Look at the space in the top right of the picture above the first full length PCI slot. I'll bet you that is the space for the ISA controller chip. It looks like it was left out since the motherboard does not have the slot installed. This is for an optional Creative/Ensoniq ES1373 chip. The mobo …

GeForce2 MX cards are dirt cheap still. They come with 6ns or faster SDRAM.

The mobo to the left is IBM Opal with an IBM 486SLC2. They used two PAL16L8 and one PAL16R4 logic chip to glue 32-bit VLB and 16-bit system bus. The performance is quite decent for what it is and there are no issues AFAIR.

Wow, I can't even imagine the compatibility nightmare of a VLB to PCI bridge. Yikes! :lol: VLB is a direct extension of the 32-bit system bus. It may be implemented on 16-bit and 64-bit system buses, too, with a buffering logic. There is no VLB to PCI bridge because it doesn't make sense. A host to …

Maybe someone with more technical knowledge than myself can explain it, but on those VRMs that come with the FIC PN-6210 board I have noticed they do run rather warm. I have different model VRMs and some run much cooler and don't have those heat plates on the top like in your photo. Any ideas why …

I see it's timedemo2 on your screen shot. That is because once the timedemo1 finishes, the timedemo2 starts automatically. The 19.1 fps is from the timedemo1 result, not timedemo2. How do you guys get timedemo1 to stop once the benchmark concludes? For me, the timedemo's keep playing in loop. …
Re: The World's Fastest 486

And I wonder: are your PCI slots running at 33 MHz? Let's say you wanted to set your CPU at 120 MHz (or even use an Am486 DX4-120 Enhanced WB), would you have been able to set the FSB at 80 MHz, CPU at 120 MHz, and the PCI slots at a real 40 MHz speed (instead of those weird downclocked …

Is a 5x86 considered a 486 ? or should it be "Worlds fastest Socket 3 Motherboard" ? AMD 5x86 is identical to 486 by architecture. There are 486DX4 chips with 16Kb write back cache. Some AMD 5x86 were labelled 486DX5. Cyrix 5x86 is a cost reduced version of 6x86. It has only one ALU like all other …

I pulled my IBM 5x86c-133/2x system out of the closet and re-ran Speedsys and the Quake 1.06 timedemo1 at 320x200. quake.exe -nosound -nomouse I've attached the results. It reported 19.1 fps.

any chance of a quake score? how come you soldered the new cache back in or was it the previous owner? No sockets that size or they are smd, can't make out on picture very nice clean system!

It's a smaller brother from Trio64. Performs very good in DOS (pretty much as good as Trio64/Vision864) and average in Windows. Price wise I'd say it's not on the expensive side. Trio32 has 32-bit memory vs. Trio64 with 64-bit. Although there are many Trio64 cards with just two 16-bit EDO chips …

Well, Ziff-Davis CPU / FPU enchmarks are quick and their results are quite reliable. They don't use MMX, SSE, 3DNow! etc. When I test overclocked CPUs, I use a simple yet very extensive "benchmark". Boot an old Linux / FreeBSD / NetBSD release and compile a generic kernel with 'time make'. Compilers …

Many say EDO and SDRAM run about the same speed on s7 but in reality Speeds beyond 66mhz + SDRAM and more than 64mb make things run a little better than edo since you need to pipe straight off the uncashed ram EDO wasn't supposed to run at 100MHz. 75MHz was fine, 83MHz with 50ns chips was also fine …
