I have an XFX Radeon HD 5750 that I've overclocked with specific settings:
ATI Radeon HD5750 1gb GDDR5: GPU set to 830 MHz, Memory at 1335 MHz.
Yet in CCC and other programs, the GPU Core is reported as 300 MHz instead of what I configured. Despite this, my benchmarks still show improved performance compared to the stock values. Could you have any suggestions as to why this discrepancy occurs? I'm currently at work, but I can share screen captures when I get home. You can also find my system specifications in my profile below for reference. Thanks!

I have an XFX Radeon HD 5750 and I've overclocked it as described:
ATI Radeon HD5750 1gb GDDR5: GPU set to 830 MHz, Memory at 1335 MHz.
Yet in CCC and other programs, the GPU Core is listed as 300 mhz, not the one I configured. Despite this, my benchmarks still show improved performance compared to the stock settings. Any suggestions on why this happens? I'm currently at work, but I'll share screen shots when I get home. You can also find my system specs in my profile below for reference. Thanks!

They don't experience thermal throttling in that way... so when not gaming, they lower their speed to save energy. Not entirely certain, maybe it's incorrect.

300mhz is the idle speed, not the maximum. Do you have two monitors? Usually the idle speed is lower than that. On my 5770 the idle speed is 157mhz, but when you connect a second monitor, even if it's not in use, it idles at 400mhz.
If you download gpu-z and run a graphics-heavy program like 3dmark06, you'd see the minimum and maximum clock speeds and it would reach the 830mhz you set it to.
Thanks! That clarifies a lot. I thought that might be the case, but wasn't sure.

I have an A 5770 that's been overclocked. The core clock is 960 MHz, memory clock is 1350 MHz. However, when running 3dmark, gpuz, and vantage, the reported core clock is 157 MHz with a memory clock of 300 MHz. I'm confused about this discrepancy.

I faced the same issue but resolved it by using a different monitor.
