Clock is set to "clk2/10" you say ? Does that mean the rest of the BIOS timings are not set for maximum performance ? I am sure they are, just checking. If the chipset istelf is not great, then there is nothing you can do, but in many cases the chipset is fine, just the BIOS is not good. You can try …

Btw, there are many motherboards out there that deliver good CPU/FPU/RAM performance, but suck at dealing with graphics. Funnily enough, not far ago i spent some time to identify and benchmark some of the worst offenders in this department. You think your FPS scores are not great ? There is much …

I think that both pcpbech and 3dbench are in general CPU bound. If your VGA is at least decently good, you will be measuring CPU performance mostly. The threshold for VGAs is so low that you will need a real underperformer like entry level Realtek, or Trident, to affect the scores. Even Doom is …

Well, lets see how the IE5 thing turns out. Make sure to report when you get hit with exploit for a first time as well 😁 Btw, i just checked some results i posted a while ago on the "systems specs" forum and my FasMath (on a clean oc'ed 386dx) churns cool 145 fpu scores.

Very interesting thread. Thank you Feipoa for the time spent on this. Couple of notes for what they are worth: I think the best way to test 387 class FPUs is to run as heavy as possible (based on one's patience) 3d renders with software that was available at the time. If we limit the choices to DOS …

I don't remember them suffering from low reliability, but they were not great at floating point calculations - 3d rendering, cad/cam, etc.

Can you comment on your intention to switch to Voodoo ? I never had good experience with VIA chipsets. Wonder if you have some observations that you can share ? In general, what do you think about K5 CPUs compared to their counterparts at the time ? Good stuff.

Installed the Adaptec SCSI adapter to the 386 PC. Updated the main post with few more screenshots for Speedsys and Coretest tests. In a nutshell - it boosts the disk speed by about 1Mb when the system is running at 40MHz and with half a megabyte when running at 45MHz.

@mrau Tested 486DX5 Matrox and Cirrus Logics at 8 bits in Win95. WT2 reports no performance difference compared to their max bit depths. A bit suspicious i admit. @rasz_pl Updated the 386 Doom tests according to your suggestions. Also, converted all Doom charts to FPS. @disruptor I hear you about …

I have couple of VL cards from the '93/'94 period - cooking a "traditional" 486DX2 build with them atm. Updated the post with the VLB tests as well. All BIOS parameters are at their lowest timings (2-1-1-1, 0 waits, etc). Using 10ns ISSI chips. Had to sort through a bunch to find the right ones, …

The comments about the 286 rig made me look up benchmark results posted on the forums and i am realizing now that the other two builds are quite of performers as well. :blush: That's a WinTune 2 screenshot with detailed breakdown of the video card test. The test is composed of multiple tasks and …

Tbh cannot remember, it was a while ago, so let me run some bmarks and post the numbers here.

The 386 was tested that way. The thinking behind it: When the frame rate is too low, the measuring step is too big and we cannot register the more granular differences in performance between the video cards. I can run and post the full screen low and high settings for doom for completeness, if you …

@rasz_pl You are correct - min settings mean low detail and smallest possible playable screen area. @snorg Acrylic cases: https://www.aliexpress.com/item/QDIY-PC-D777XM-Horizontal-Mirco-ATX-HTPC-Acrylic-Transparent-Desktop-PC-Computer-Case/1785742866.html?spm=a2g0s.9042311.0.0.2c8a4c4dHXbBKK The …

Thank you for the positive feedback guys. Yes, the 286 turned out be a beast. Making "ultimate" PCs was never the goal, but i may snowballed a bit in that direction along the way. 😀 @almoststew1990 I hear you. I have few more rigs laying around and some of them are baffling slow for their class.
