Nvidia 8800 GT - Which One?
There are 2 8800GT products: N801-AR and N802-AR. The 801 is 600 MHZ
core and the 802 is 650 MHZ and advertised as overclock/superclock. Given over clock capabilities which one is really the best buy since the 801 is about $30 cheaper and presumambly can be clocked to 650 MHZ and beyond. Not sure if the 802 is max'd out or not. Anybody know of these things? Best, Mike |

Anybody know of these things? Best, Mike It really depends on how comfortable you are doing the overclocking with various utilities or rewriting the BIOS settings. The superclocked ones are supposedly higher binned DDR3. Whether that's true or not, I don't know. I bought a superclocked Galaxy 8800GT with the GPU at 600Mhz and ram at 2.0Ghz. That turned out to be too high for the RAM in some games, with hard lockups and red pixeled screens during gameplay. After extensive use of Rivatuner trying out various clock, shader and ram clock settings and playing in the games I play, I simply rewrote the cards BIOS to 675/1650/1900 for GPU, Shader and RAM respectively. It's faster with these settings than the factory 2.0Ghz DDR3 speed. At the same time, I reset the fans speeds to 25% idle and 70% max load to get rid of the dust-buster noise the enclosed 8800GT's are famous for. As quiet as my 7800GTX was now. You don't have to rewrite the BIOS, but that way I don't have to load Rivatuner every bootup. |

Anybody know of these things? Best, Mike It depends on your circumstances, some games at some resolutions don't preform any better with a higher core speed, or with a higher shader speed, memory speed etc. If that is your only criteria, FPS, do some research and check out benchmarks of your favorite games to see if they respond to overclocking. Also, with nTune, you can set profiles to overclock your card only in those games that benefit from it, further negating the need for a BIOS overclock. |

Overclcoking a card permanently is a simple video bios flash away so why should I pay extra for that? |

At which shop are you getting the $30 diff. from? At both eVGA and Newegg,
the diff. is about $20. $20 out of $240 MSRP on the 801 model is about 8%. Forget GPU clocks, look at the RAM clocks. 801 runs at 1800 MHz effective. 802 runs at 1900 MHz effective. The 8800GT is sensitive to RAM clocks at high res + AA, so you can get close to 1:1 scaling. Is 5% extra performance worth the 8% price diff. to you? Bear in mind 802 may have higher-rated RAM, so it may have some overclocking headroom left. The reason: one method (out of several) nVidia used to reduce the production cost of the 8800GT compared to the older G80-based 8800GTS, is downgrading to a 256-bit memory interface from a 320-bit interface. To compensate for this loss of memory bandwidth, the RAM has to be clocked higher. -- "War is the continuation of politics by other means.

Thanks my friend. And yes the price spread between the 2 is closing,
looked like $12 after rebate at newegg. One forum thread I found on this subject suggests that when it comes to overclocking it all depends on the characteristics of the particular chipset you end up with. This is of course consistant with my electronics/computer design background (getting somewhat dated).

In fact, I have already done that once. I had to downclock the ram on a card because the ram was factory overclocked and couldn't do the rated speed but then I decided to send it back for an RMA because I paid extra for the overclocked speed so I just set the vga bios back to default and shipped it back to the manufacturer. I'm not interested in overclocking anymore because the gains are not all that much anyway. Sure, the score in 3DMark goes up but it is barely noticeable when playing an actual game. Unless you do massive overclocks on video card and cpu it is not really worth screwing around with IMO. I don't even OC cpu anymore and I'm someone who used to OC religiously. |
