Geforce FX5700 Ultra 128Mb Core Clock Problem

[Darkhound]

I bought an FX5700 ultra 128Mb about 6 weeks ago. The proper default clock speeds are 475MHz Core and 906MHz Memory. The thing was fine (I think) until last night. The card is overclocked, but by no more than 10% which to my knowledge was well within safe limits, I did it gradually and everything.

Last night though I noticed Riva Tuner was reporting 300MHz core in the 'real clock speed' box or whatever it is, the one below the number you adjust in drive level overclocking. So i check AIDA, and sure enough its saying the GPU core is 301Mhz, far below the 475Mhz its supposed to be. If I change the core speed in Riva Tuner or set to defaults, it shows the correct values again, but then goes back to 300MHz a few minutes later.

Does anyone know whats going on? Have I screwed up my card or what? I have a 350W PSU, a thing of note is that I used to have a USB lamp and it used to flicker quite a lot and especially when taxing operations e.g playing games were being carried out. Is it possible that the lower core speed is because of a lack of sufficient power?

Thanks in advance.

The FX series goes to a lower clock speed in 2D mode, and 300MHz sounds about right for a 5700 Ultra.

Yeah the 2D mode is 300MHz and the 3D mode is 475Mhz. Trouble is I cant remember whether it always said 300MHz or whether it used to say 475Mhz. Is there any way for the card to 'fall into' 2D mode and use a 300Mhz core? If so how do I get it back to normal. I ran Aquamark when it was normal and got a score of 28500 roughly, now I'm getting about 26500. Also on the ARC on the Aquamark site, its saying my card speeds as 50/200, when it used to be like 109/200.

Could a problem such as this be caused by overclocking?

AM3 does not read 5700 speeds correct for some reason. mine was the same way. do a comparison and see for yourself.

I also own one, OC'd to 525 MHz in 3d mode, but operates at 300 MHz in 2D mode. You're just fine You'll find that the 5700u is quite generous as far as overclocking goes.

Yeah cheers for all the help guys. As far as overclocking goes, It seems mine keeps going back to stock speeds for some reason. I'm not too bothered about this because the things plenty fast as it is, but anyone have any idea why its doing this?

Download Coolbits and see if that will let you OC it.

If it's going back to stock speeds, you prolly haven't clicked the box at the clock settings called "apply settings at startup" That should fix your problem.
