7800 Overclock Record
Note: OC values are now net clocks (clock plus delta) for better comparison with non-delta cards (GT, GTX 512).
Average Usable GTX OC by Vendor - Top 3
What does this tell us?
I have created this thread to gather results of all nVidia 7800 series cards. This is not benchmark summary, but a compilation of potential for the cards.
There are many aspects to the value of a video card. Some want the best bang for the buck and others want the best card, period. With the information gathered, you may find that a particular brand card may have better specifications stock, but have very little overclock potential past the defined clocks.
So, for example, if all 7800 GTX's clock to 500 on the core, does it make sense to pay a $100 premium to get a 490 core? Do the cards that clock to 490 idle much cooler? Is the bargain oem MSI card as good as the more expensive BFG? Well, it will all depend on your goals for the card. Do you want to maintain a warranty, or have different cooling in mind so you can overclock the card?
Hopefully this information, once more extensive, will help you choose the best card for your purpose and budget.
How can you Help?
Share information about the performance and build quality of your 7800 series card. Please note, this is not a competition, but simply a record of a card potential (and real) performance . Please, don't fry your card trying to get some unrealistic clock to bump up a little higher on the list. If you could use the latest WHQL driver and list what CoolBits autodetects along with your max usable OC, we may be able to see a pattern by brand, etc.
I will update the first page every weekend.
Use this format (if you don't have it all, just list what you know)
Stock clocks: core / mem
Coolbits Detect: OC core / OC mem
Usable OC: OC core / OC mem (can you complete a few runs of 3Dmark05 without issue and no artifacts? AM3 is too quick of a test to really load the video card. Can you game at that setting?)
Idle temp: (NOT at boot up, but after a few hours of running at 2D) you may want to also report your ambient is a significantly warmer than noraml room temp (ie, it is 85 F in your house with no AC)
Cooling method: waterblock, stock, Zalman, etc
And, add any other relevant notes you think may be helpful such as:
volt mods, LN2 cooled, etc.
For example, here is an autodetect result:
