v3 3000 + fan, how much overclock? (Read 201 times)

RaptorZX3 Full Member Offline Canadian 3DFX user Posts: 218 Montreal, Quebec (Canada) Gender:	v3 3000 + fan, how much overclock? 19.11.13 at 11:38:53 i found a fan i can use on my V3 3000, either AGP or PCI. It's a fan that was used on a Pentium 1 CPU cooler. Now i wonder...if overclocking is a heat problem only for the card, how much overclocking i could put on that card? note: this board have PCI only (Asus MEW-AM), this is why i use a PCI card on this one...

seeing that the card has -6 ram, which is rated for 166Mhz, I don't think you'll get much out of it, maybe if yer lucky you'll reach V3 3500 speeds (183Mhz) but I wouldn't get your hopes up.

In this case the limiting factor is the ram, V3 chips can run upto 200Mhz in some cases, but most will do 190 if I'm not mistaken.

Reply #2 - 19.11.13 at 13:23:42 yeah since V3 2000, 3000 and 3500 all use the same GPU, i guess only the speed change on it. And i guess this is why they shrunk the heatsink for the 2000, so it would be harder to overclock it.

That is true, they are all exactly the same GPU, aside from speed and a few features like tv-out and the break-out box of the 3500.

Actually no, they did that to save costs, you might think that such a small difference in size can't make a difference, but take that little bit of metal and multiply that by millions, and you have a lotta metal on your hands.

i tried overclocking the AGP version i have of the V3000 here, and tried the benchmark with Dethkarz, with the first track.

Without overclock (166Mhz): about 55fps average
With overclock (183Mhz): about 61fps average
(higher FPS on the 2 other tracks for both results)

Using latest official drivers.

Tried this on an Asus P3B-F rev1.03 w/latest beta BIOS (with 700Mhz 100FSB and later 1Ghz 133FSB overclocked 133 FSB/33 PCI, no change in performance on both reads, as the bottleneck is the GPU here)

I've put the fan you see in the picture on this V3000AGP as well, to keep it cool
