Re: Is it worth it for me to get a Voodoo card?

@drosse1meyer You can always try to overclock your cpu to 200 MHz (just set multiplier to 3x) and check how much your framerate improve. It depends on the CPU. Some of them are multiplier locked (limited). I have a Pentium 166 (non-MMX) which will ignore multipliers higher than 2.5 (basically, it …

I bought a voodoo 3 because i had a better deal than for a voodoo 2. And a voodoo 3 can be use in my pentium 2 and 3 too with great performance. Of course, I wish I could/did find a v3 PCI for less than a v1/v2 ;) What board do you have? it seems both my socket 7 mobos don't like to give video with …

2. Mine has 640kb on picture boot screen. So does it include a upgrade isa ram memory card ? or it could be on the motherboard ? I have 2 5160, the earlier version has a max of 256kb on motherboard and my later version has a max of 640kb on motherboard 3. I think it comes with a cga card, could i …

If I remember correctly, you were concerned about timing compatibility with the 4.77MHz IBM PC in the thread about your Turbo XT. Now that you got the "real thing", not only the 5160 motherboard, but also likely the original CGA, you have a system that is exactly the original speed. If having such …

Tomb Raider 1 runs perfect Not on a Voodoo3. It may run with a stable frame rate (locked to 30) but it suffers from some graphical glitches such as Lara missing her shadow, pistols flashing white when AA is used and gamma being too washed out, without the possibility of adjustment. For the best …

Hi guys! I'm very happy with my pci voodoo 3 2000 with my pentium 200 mmx. I have good result. Even need for speed iii is very playable, more than 30fps most of time. Screamer 2 runs perfect. Tomb Raider 1 runs perfect, Croc runs great, Moto Racer runs great. ( with the same voodoo 3 i even played …

The IBM 5150 and 5160 mainboards are not designed to run at any other clock than 4,77 MHz. Because not only the processor clock, but also the CGA video timings, the RAM refresh timing, the system clock and the speaker frequency are derived from that clock, running the processor at a higher clock …

Hi! I have a few questions. Thanks. I made recently a topic about my 8088 xt turbo 8mhz motherboard and cpu i bought recently. But i have a deal for a complete IBM 5160 computer without monitor and keyboard. 1. Which cpu upgrade is it possible in a IBM 5160 ( and 5150 ) ? Is it possible to upgrade …

renejr902, you PMmed me with flattering words about my knowledge - but when it comes to XTs it's pretty limited. Still I'll do my best to answer the questions. 1. what vga card do you recommend for my 8088 xt build ? ( i will use 16 bit vga isa card that work in 8bit) 2. Is it better the slowest …

1. These days Getting a working 8 bit VGA that doesn’t have compatibility issues is key, many Oak cards in my experience are more EGA compatible than true VGA, in fact my friends packard bell 486sx25 had oak VGA onboard and couldn’t run Monkey Island in VGA mode. 2. Speed is less important than …

Hi! I will post more info in the next days. But for now, i bought a 8088 xt clone with a fujitsu 8088-2 cpu and 640kb ram with a turbo xt 8mhz motherboard that can run at normal 4.7mhz or 8mhz. I have some questions. ( i had a ibm xt 8088 with a cga monitor when i was young and yeah i know a lot of …

The 386sx 16 is a dud on terms of a 386, but it gives you basically some 16MHz 286 power with the 386 instruction set. It does everything the 286 does, and can even switch into protected mode and back without half. The 286 has difficulty with that. So yeah, it covers the 286 need it you ask me :) …

Thanks again for answer. Yes i just found the deturbo jumper and my 386 sx 16 cut mhz in half at 8 mhz. I tried Landmark LM20 and it runs at 8.53mhz AT speed and sysinfo 6.0 give me 45 of score for cpu benchmark, exactly the same than a 286 8mhz at. So i'm all set. But does it run really and …

The 386SX is just a slow CPU, especially at 16mhz, it's a bit slower than a 16mhz 286 (but more capable with its instruction set). There is no cache on this board. Cache wasn't common on 386SX platform, it was mostly a DX thing. Can you please take a clean picture with all the expansion slots empty …

In term of games and speed sensitive, do i need a 286 computer, if i already have a 8088, a 386 sx 16 and a 386 dx33 ? any advantage for any games or software with a 286 ?

The 8088-2 is not a clock-doubling processor. The "2" denotes the processor as "second-class citizen", being able to operate at up to 8 MHz, whereas first-class 8088 processors named "8088-1" can operate at up to 10MHz. Either way, the processor operates exactly at the frequency as generated by the …

Thanks :) There's probably a turbo header on your motherboard too Thanks a lot for this information, i found the turbo header by myself. I checked with Landmark LM20 and Sysinfo6 and i got 4.5 on sysinfo6, exactly like a 286 8mhz at cpu. It seems that turbo cut the mhz speed by half, thats great …

A lot of them that are popular on here are for slowing 486 or pentium machines so might be too slow with a 386sx16, so I thought those ones would be more the right ballpark. The utilitie work great , i found a newer version at 4.10. In this new version you can select mhz for the cpu instead. It …
