Most non-Coppermine/Tualatin ready motherboards gravitate around 2V or higher vcore. The Freeway one in particular can go down only to 1.9V. Most Coppermine CPUs are between 1.6-1.8V, so you can still use them, given BIOS does not freak out on you, which is also rare. But Tualatins are around 1.4-1. …

Yes Andrew. Agreed. It is implied that these adapters are inserted between CPU and underlying socket (being this on-motherboard socket or slotket one). I can see how it was not clear from the wording in the previous posts. These Tualatin adapters are much better option than modifying Slotkets, to me …

Good stuff Chadti99. All the right moves. Thermal paste, 4 rods heatsink, high-enough voltage to the Peltier for freeze. However the Doom score is too low. You should be over 70 fps already. I think this is LuckyStar revision C2 motherboard that comes with 15ns L2 cache chips. That most likely won't …

Asus S370-DL slotkets have voltage regulators. At the end - after posting the above - i actually made dual Tualatin-S work by feeding them 1.75V. No idea why this particular voltage did it. Still, didn't keep the CPU in the first slot inserted for too long. The last thing i need now is fried …

Pentium 3 class hardware is of interest to me, especially Slot 1 and 2 stuff, so naturally built this dual Slot1 high-end workstation / gaming pc after the thorough examination of bunch of Pentium3 motherboards based on 440BX, OR8#0 and VIA chipsets. Some of that documented here , here , here , here …

Heh, but i took your advise and keep temperature ~820F these days. Something was off with the silk screen. Top layer immediately "burned", became dark and bulged up with air bubbles forming underneath. Separated from the base. So it became a thin crust that cracked and fell on touch.

The "oven" was figurative talk. What I meant was - took the picture right after completing the heatgun work, before cleaning things up. Quick search revealed several different types of coatings they sell - acrylic, silicone, adhesive variations. Which one you recommend?

To my surprise the silk screen reacted badly to the heat gun: 20211017_192627.jpg Took the picture straight out of the oven. After cleaning and removing the …

This is unfortunate. For POD L1/WB i use the same jumper configuration from the picture you posted several posts ago. Tried this morning Win95 and 98 - no perf difference. VLB is in 0-ws and <33MHz, right ?

While writing my previous reply I was thinking about why the difference since we use the same hardware really. Ruled-out already the 2TheMax culprit. It is unlikely that Asus gimped the 2.1 VLI revision. So it must be something subtle on your side. Let's try the basics as a starting point: …

I can verify again the 18.8 score, but not far ago i checked it because of something else - it held true. So, how you are getting 27.1 in Quake 1 with POD100 ? What is your formula ?

@Chadti99 So, ran couple of DOS interactive graphics tests for the two ARK1000VL cards. No difference in Quake1. Tiny difference in Doom - 1222 vs 1223 realticks. Tiny difference in Wolf3D - 0.1 fps. Basically a rounding error. If you setup jumpers and BIOS as shown below, you should be able to hit …

VX1 are basically fancy Permedias (cannot remember from the top of my head were they v2 or v3 based). Probably that's why VX1 inherits some "features".
