Galaxy Nvidia GeForce GTX 465 Review
Overclocking
Furmark Stability test was used to find the maximum stable overclock. The fan was left running at 100% to keep the GPU temperatures as low as possible and allow maximum possible overclock.
For overclocking this video card, I had to download version 1.6 Beta 5 of MSI Afterburner, which adds support for Nvidia GTX 4xx cards. This tool can be downloaded from here. I started overclocking by increasing the clocks 10 MHz at a time. The overclocking was quite an experience as it took a long time because the video card just would not stop overclocking. It kept going on and on. Finally, I was able to overclock it from 608 MHz/1215 MHz/3348 MHz (Core/Shader/Memory) to 790 MHz/1580 MHz/4000 MHz (Core/Shader/Memory) which gives us an overclock of 30%/30%/25% on core, shader and memory respectively. This is an amazing overclock. Voltage control is not possible on this card, otherwise an even greater overclock would have been possible.
As you can notice that we are maxed out on the core clock in the Afterburner tool. To verify if I could increase the core clock more than 790 MHz, I downloaded Nvidia system tools which also allow overclocking. The Nvidia system tools can be downloaded from here. Unfortunately, core clock was not stable above 790 MHz. If the voltage control was allowed on this card, I’m sure we could increase the core clock above 790 MHz.
I see you had less than stellar performance in CoD 4 just like I did. For me the GTX285 outruns the GTX470, and the gap is even wider with Windows 7.
Dude, your graphs are completely screwed up. Lower numbers are sometimes showing higher bars than higher numbers and vice/versa. You have a lot more work ahead of you. This article could not possibly have been edited and proofread as there are several model number, shader number mistakes throughout the article.
Nice thorough article, but it shouldn’t have been released like this. And if somebody did edit the article, fire them. 😉

Hey Keysplayr, I think that the “screwed up” bar charts are actually cool. I noticed that the length of the bar is the addition of the minimum frame rate plus the average, then plus the maximum.
It gives greatest emphasis on the minimum, and also greater emphasis on the average than the maximum. Say, if the minimum is really low, then it will really affect the rest of the bar. (If the game dips to the “average minimum” quite frequently, say a few times a minute or so, then I’d definitely emphasize it the most.)
Oh well, yeah, I know it’s screwed up anyways, but this is an awesome review. Didn’t know about the RE5 3D vision demo (one of my fave games and I have Stereo 3D)!!! Thanks, MrK!
Only 1 in a hundred thousand would notice those “errors”, and only 1 out of them all said anything. =P
Good article, although it would have been nice to see that card face against the 5850!
I agree Bo_Fox, this is a pretty good review and I can’t wait to get my GTX 465 to replace my aging AGP slot’d PC with a new system.
The price seems very reasonable at less than $300 at newegg
it is a pleasure for me visit your blog.
I wish more people would write sites like this that are actually helpful to read. With all the garbage floating around on the web, it is rare to read a site like yours instead.
I feel like I’m always looking for interesting things to read about a variety of topics, but I manage to include your site among my reads every day because you have interesting entries that I look forward to. Here’s hoping there’s a lot more top-notch material coming!
Someone I work with visits your site quite often and recommended it to me to read also. The writing style is excellent and the content is relevant. Thanks for the insight you provide the readers!
