Not much action on the rivatuner forum lately, so i'll post one myself<br> Courtesy of rivatuner, my tnt2 vanta 32mn 100/125 mHz now runs at 125/160.<br> There is no oncard ventilator. Just this plastic little heatsink.<br> I could not remove this from the chip, for fear of destruction of the chip itself.<br> So I attached an older pentiumPro cooler from Titan. I attached the heatsink of the card and the cooler with thermal padte and two drops of superglue. It looks awfull, that little card with the big bloc on it, but more importantly, will it do the trick?<br> I reckon that the heatexchange between chip and the platsic heatsink on the card is not that good to start with, so nailing two heatsink togethre maybe wasn't that smart.<br> Maybe better to disattach and only use the ventilator from the pentiumcooler, then i have to make a construction to lift it up a little to avoid it coming directly in contact with the card.<br> How high can that stable tnt2 vanta get clocked?, can i crank it up now because of better cooling, if anyone knows please feel free to respond.<br> <br> Unwinder, you were right on the z-buffer not hindering performance, but you knew that all along ofcourse.<br> When does registered version come out, I want to know what all these wonderfull poweruser settings do<br> <br> stefan <IMG SRC="smileys/biggrin.gif"> <br>
<BLOCKQUOTE>quote:<HR>Originally posted by stefan:<br> <b>Unwinder, you were right on the z-buffer not hindering performance, but you knew that all along ofcourse.<br> </b><HR></BLOCKQUOTE><br> <br> If i remember correctly the question was about w-buffering.<br> In theory a Z(w)-buffer will affect performance (even if only because of size and acces). In 32 bit Unreal 1, not UT, i found out that switching to a w-16 increases performance by 2 frames <b>but</b> it makes appear those ugly artifacts again( specially at the 8launcher).<br> I prefer playing in 16 bit with a w-32 buffer. Didn't even bother to benchmark with a w-16 buffer beacuse i like to play without artifacts as much of possible.<br> <br> Kakaru
<br> Oke Kakaru, you had me there; i meant w-buffer, i'll have to be more carefull if even others remember my own questions better than I do!<br> Hehe,<br> The cooling seems to be very good, i checked temperature manually(that means with my indexfinger at the other side of the card, right underneath the chip), and it was much cooler. Also the card as a whole felt much much cooler, before you could not touch it.<br> I can overclock the core to maximum (150) and everything works fine.<br> Memory will fail over 175 mHz, i think the cooling doesn't help that alot.<br> But frames dont go up anymore. In QA i noticed a slight increase, UT nothing. The bottleneck is really the cpuspeed, i wish i could overclock that as easy as the videocard.<br> Because of the little performance benefit i set back core and memory to 125/160. It was nice to try it however.<br> <br>
2 stefan<br> <br> We had nice article about handmade coolers and videocard overclocking on <A HREF="http://www.nvworld.ru." TARGET=_blank>www.nvworld.ru.</A> So u had to study Russian, dude <IMG SRC="smileys/wink.gif"><br> <br> 2 Kakru<br> <br> > I prefer playing in 16 bit with a w-32 buffer. <br> <br> U're a bit incorrect. U cannot force 32 bit w-buffer in 16 bit modes, but u can switch W-buffer format for both 32 and 16 bit modes. By default Detonator uses scaled integer W-buffer in 16 bit modes and floating point W-buffer in 32 bit modes.

Still there were some great info there, like a -0.5 lod in 6.xx being identical to a 0 lod bias in 2.xx, and the pictures to prove it.<br> <br> About w-buffer - i read the official w-buffer paper from nvidia, where they mention w16scale and w24scale and integer/floating point but i didn't understood what values should i give to these values. Specially that 2^127 really killed me so i finally decided to let those values default and didn't bother with them anymore.<br> <br> yes, u are right, i mean w-buffer format. In 32 bit w16 is faster then w32 but specially at close distances (where w is worse then z) it introduces artifacts. I hate artifacts <IMG SRC="smileys/wink.gif"><br> I play 16 bit color and w32. Been trying 32 but for a strange reason although fps>30 at 800*600 gameplay is <b>very</b> choppy.<br> <br> Kakaru
Stefan, you're nuts if you think that overclocking a processor is harder than a gfx card. <IMG SRC="smileys/smile.gif"> What cpu have you got?<br> <br> You can probably remove your current heatsink (usually they are only clipped on) and replace it with something bigger (ThermoEngine is what I have here) and increase your clock multiplier by 0.5 (ie times 4 goes up to 4.5) without messing with the voltage at all.<br> ThermoEngines are pretty cool (no pun intended) as they already have thermal transfer pads fitted guaranteeing a flush fit. So no messing around with Arctic Silver.<br> <br> The Heatsink on your cpu is unlikely to be plastic. Anodised aluminium at a guess. Scratch the edge of it with a sharp knife. Is it silvery underneath?<br> To get it off stick in the freezer for half an hour, and carefully remove it with a flathead screwdriver. Clean the rest of the glue with meths or something.
<br> Yeah, I know,<br> I have used softfsb to punch up the front side bus, and it does the trick.<br> But the only reason I would do that is to run UT more smoothly.<br> I have one of the first p3's. cpu is at 450 mHz.<br> It is clipped on the heatsink <br> Clocked at 500, UT hangs upon loading the menuscreen.<br> Other games and applications work fine but it is only for this memory and cpu hogging dream of a game that i need the higher fsb.<br> My board (and bios) is more made for stability than speed.<br> So i cant go messing with voltage and the more "advanced" tactics, too bad really.<br> The bios is crippled by not allowing any changes in cpu or pci speed.<br> The components are oke<br> So I dont think overbussing will help me here. <br> But I might go for a better heatsink, who knows maybe it will make a difference nonetheless. <br> I'll check out the thermoengines<br> <br>
hmm.. weird.. i have a Riva TNT 2 M64 32mb ..<br> i clocked it to 156mhz core / 159 mhz mem.<br> i have a heatsink on it .. and a big FAN slot cooling tha card down.<br> 2weeks now .. and no prob's yet.. <IMG SRC="smileys/smile.gif"><br> i really beleive the card can go much further.. tho i tried clocking it to 180/180 and it made some prob's .. on 190 it faild...<br> but its still alive and rocking here <IMG SRC="smileys/biggrin.gif">
I have a tnt2 m64 16 meg running at 160/180. i have two chipset fans, one on the chip, and one on the back of the chip. I have been doing this for at least 6 months now.
hi<br> <br> I have an ELSA ERAZOR 3 TNT 2 Graphics Card. I updated the card with a new BIOS and then i overclocked the card upto 160/190MHz. Now I have changed the Cooler and put passive Coolers on the RAM and now I can play on 190/200MHz.<br> <br> <IMG SRC="smileys/biggrin.gif"> <IMG SRC="smileys/biggrin.gif"> <IMG SRC="smileys/biggrin.gif"> <IMG SRC="smileys/biggrin.gif"> <IMG SRC="smileys/biggrin.gif"> <IMG SRC="smileys/biggrin.gif"> <IMG SRC="smileys/hot.gif">

I updated the card with a new BIOS <br> ----------------------------------------------------------------------Is the erazor 3 a tnt2 with 64 bit memory bus? like the vanta and m64?<br> 190/200 is very nice,even for regular tnt2, in case the erazor is m64; did you use a bios for a differnt tnt2 maybe? <br> And do you not have activecooling on the card itself? <br> Nice idea flashing the card, well not really an idea, since it is custom practice for upgrading components, but nevertheless intruiging, more power to you! i am gonna look into it.<br> <br> Anyone know what happens when flashing your card with another cards bios( but very related like regular tnt2 and tnt2m64)?
<BLOCKQUOTE>quote:<HR>Originally posted by stefan:<br> <b>Is the erazor 3 a tnt2 with 64 bit memory bus? like the vanta and m64?<br> </b><HR></BLOCKQUOTE><br> <br> The vanta is 128bit, just lower clock and memory speeds than the standard TNT2. Only the M64 is 64bit.
