NVIDIA Geforce 8800 Series Overclocking Guide

jmke · 18th May 2007, 13:55

In this in-depth guide we show you how the extract the highest performance from your Geforce 8800 video card, push that GTS past GTX speeds and turn that GTX into an Ultra-beater by following the steps outlined. We evaluate the performance increases along the way by using real world benchmarks; Can a $250 8800 GTS compete with a $500 8800 GTX? Read on to find out.

I would like to ask one thing. In Riva it shows that my card moves in steps but in nMonitor it shows what I have it set to in Riva. Which one is correct?

u card clocks in steps this comes treu bios , there is a bios that fixxes this

. riva is always right

Where can I get a BIOS update? That kind of makes me mad at a $650 card. I have NiBiTor but modding the BIOS scares me. My card is XFX 8800GTX XXX. Where can I get an update?

Last page there is a link attached to the EVGA bios, which enables overclocking per MHz (GTX!). You can download the latest BIOS updates at mvktech.net, though the situations that you would have to update your BIOS in order for your card to work properly are very rare.

Hi guys. This is just a cheap way to keep your expensive hardware nice and cool. My temps dropped about 20°C

I use rivatuner to set the fan speed to 100% (as mentioned in the article). Secondly, I have an Antec P180B which has a HDD case in the middle. I added the 120mm fan from the bottom of the case onto it which blows cool air across my videocard.

I also added an Antec Super Cyclone blower. Which sucks hot air from the videocardcooler (videocard exhaust a lot of hot air through the slots on top of the cooler). Costs about $11,99 hardwareprice.net link

I mounted the blower 1 slot lower then the 8800. So there's 1 slot space. I tried mounting it directly under the videocard but that didnt work.
I know this blower takes up 2 pci slots, but for now I'm not going SLI anyways. When I do, I'll probably get two single slot blowers.

The results:

Room temperature: 19°C

Default speeds Tempratures
BFG 8800 GTS (513/792) no fan - no blower - rivatuner 60% 75°C
BFG 8800 GTS (513/792) no fan - no blower - rivatuner 100% 65°C
BFG 8800 GTS (513/792) fan - no blower - rivatuner 100% 60°C
BFG 8800 GTS (513/792) fan - blower - rivatuner 100% 55°C

Overclock speeds
BFG 8800 GTS (600/1000) no fan - no blower - rivatuner 60% 79°C (I forgot to take a screenshot, but believe me it got HOT)
BFG 8800 GTS (600/1000) no fan - no blower - rivatuner 100% 70°C
BFG 8800 GTS (600/1000) fan - no blower - rivatuner 100% 64°C
BFG 8800 GTS (600/1000) fan - blower - rivatuner 100% 59°C

I hope you guys and girls can use this info.

welcome to the forums

, thank you for the informative post!

I think you'll get better performance/noise results by swapping the blower for a 92mm fan positioned 45°C towards the card&rear with the PCI brackets removed; those blower fans have a very bad performance/noise ratio compared to normal axial fans
