OT - Overclocking V3 2000?

I don't see anywhere to overclock my new V3 card, is there a seperate utility needed to do this, or should I just leave it alone? Lovin' this card by the way! -- don [|]-(_)-[|]

http://www.3dfiles.com/utility/voodoo3overclocker.shtmlFor best results put a fan on the V3 heatsink,I used zipties to attach it. Start slow,maybe 150 mHz,give it a good work out,bump up a few notches.I'm running at 166 mHz,no lockups,completely stable. Dave K

As long as you don't try something crazy like 200 mHz,you probably won't damage your card.The default rate on the V3 2000 is 143 mHz,you may get 155-166 without a fan,but for the price of an old 486 fan it's most likely.Start with a small increase,look for any graphics corruption,make sure it's stable and go from there.

http://www.voodooextreme.com should have Gary Peterson's overclocking utility somewhere. I have mine at 173, but I get noticable artifacts on the screen in SCGT and DTR. No problems what-so-ever in Papyrus' sims. -- ----------------------------------- Morgan Vincent Wooten http://members.tripod.com/~morganv/ -----------------------------------

Over clocking without a fan, will this hurt the card? Or will it just cause lockups?

Well, it could definitely shorten its (chip's) life, but it might still last a lot longer than you'd be willing to keep the card. Do note that these beasts CAN get really hot, so hot in fact that you could burn your fingers when touching the heatsink. Common sense dictates here that it might be a good idea to go for a fan. I've clocked my V3 2000 to 178 MHz and haven't yet had a single lockup with this card. I've also yet to see a V3 2K which couldn't be clocked beyond 170 (two of my friends also have a V3 2K). For cooling I've installed Titan's TTC-002 80 mm system cooler ( http://www.titan-cd.com/sys1.htm#a ) directly beneath the card (only about 2 mm away from the chip's heatsink) so that the big fan sucks air heated by the V3 right out of the case. Bigger heatsink would generally be in order at these frequencies but the flow of air generated by the 80 mm fan seems to be efficient enough to keep the heatsink from getting hot. I just installed a thermal sensor to the heatsink, as close to the chip as possible, and plan to monitor the temperatures at different frequencies to find the "sweet point" and to set a suitable limit to the hwdoctor's temp alarm. --- Antti Markus Peteri 15 miles. your dim light shines from so far away - Soul Asylum, Promises Broken

I've been running my V3 3000 at 180 since they came out. No lockups. I just used a $4 all plastic 486 fan that clipped on the heatsink. Brian

I have mine up to 166mhz with no problems or no fan. How hard is it to attach a fan? I was reading on the web site for the over clocker and it was talking about adding tin foil and grease to the heat sync it sounded a little complex. Is it? I install all my upgrades my self. Will it snap on or will I have to***around with it? > > Over clocking without a fan, will this hurt the card? Or will it just cause

Also, cards which have Hyundai (HY) brand memory on them exhibit the best overclocking potential.

With a right kind of fan it's a snap. If you take a look at the card, you ought to find two holes cut through the PCB, placed diagonally to the GPU. Some dedicated VGA fans are attached using two plastic "rivets" which fit into these holes. If you use one of these, the fan will just snap onto the heatsink. I know some people have just screwed a fan on the heatsink but any visible damage to the heatsink will also void the warranty. --- Antti Markus Peteri 15 miles. your dim light shines from so far away - Soul Asylum, Promises Broken

For general overclocking stuff, check out my website (overclocking section) the url is in my sig, or try any of the other well known overclocking sites, namely Tom's and Anand's websites: http://www.tomshardware.com/ http://www.anandtech.com/ Specifically for V3 cards, try the following: Go in to your Windows directory and double click on Regedit.exe (or from the desktop select start, run, and type in regedit) Your Registry Editor should open. Click on HKEY_LOCAL_MACHINE. Scroll down to 'System' and select that and you will open the CurrentControSet directory. Now select the 'Services' folder. Scroll down until you see the 'Display' folder. Select it and you're in. From the 'Display' folder you may have several 000X type folders. These are your old or previous graphics card's registry settings. Leave these as they are and locate the one that is for your Voodoo 3 card. It should say something like "3Dfx Voodoo 3" next to the DriverDesc. Now select it and you will open five more folders. Open the 'Default' folder and add a NEW STRING VALUE. Name it "Grxclock". Modify the Grxclock value to whatever you fancy trying your luck at. If you have a 143MHz board (V3 2000 card) and want to try 150MHz then simply try putting in "150". For a V3 2000 card the max you should safely try is around 160 to 165, although I've heard 170 is possible. Don't overdue it, try small increases one at a time to see if they work ok. I suggest increments of about +5MHz at any one time. If the card stops working, go back to the last setting, as this indicates you have gone too high, and the card is overheating. You can add cooling (fans) or use a freeze spray which coats your graphics card chips and keeps them cool (available from hardware shops or the net). You can also try leaving one free PCI slot between the V3 card and any other cards, this aids cooling. To really speed up games using your V3 card, you should disable the V-synch option. For Glide based games you'll need to simply add in a single line into your autoexec.bat file found in the root directory. Add this line: SET FX_GLIDE_SWAPINTERVAL=0 For D3D games locate the following directory from the Windows registry: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\000X\ D3D] Then simply add this string value: "SSTH3_SWAPINTERVAL"="0" With these settings your fps should be faster. There are also utilities available from the net that provide small programs that make overclocking your V3 crad even easier, as easy as moving a slider on screen? 8-) *Peter* - http://www.cix.co.uk/~peterpc/home.html

Thanks for all the valuable info!

Thanks so much Peter, it's just what I needed. don [|]-(_)-[|] <SNIP>
