Have a NON-reference card with no voltage control? Give Sapphire Trixx a go

post #1 of 22
Thread Starter 
My two 5850's are Power Coolers own PCB design, according to every review I've seen of these cards they do not support software voltage control. And this was confirmed by MSI Afterburner as the voltage option was not available.

Cue Sapphire Trixx

This program is new to the scene and people are reporting it as being able to adjust voltage on cards that have been said to not support it.

Look at my picture, Notice how the voltage option is not available in MSI After Burner but is available in Trixx? GPU-Z also confirms the voltage change from the stock 1.1v to the 1.3v set by Trixx

Before using Trixx the max clock I could get on stock voltage was 830Mhz on the core, with Trixx I can run all the magical 1Ghz



If you're running Cross-Fire be sure to disable ULPS in the registry to avoid Trixx locking up your computer on voltage change, to do this :

Go to registry entry :

[HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Control \\Cl ass\\{4D36E968-E325-11CE-BFC1-08002BE10318}]

and change "EnableUlps" to 0 under the 0000 and 0001 or 0003 keys.

Dont you mean, Non-reference?

Nice. I found this little program out a few months ago. The registry edit really helped the crashing when changing voltage. Thanks for that. What is the maximum voltage a 5850 can take? Right now i'm running at 950/1200 @ 1.125V @ 75% fan speed. Furmark reports max temps of 66c. + 1 rep.

I've googled it and seen 1.3v as long as you can keep temps in check

Been using this for a while and it let me get to 930MHz. But, I can't go over 1.23V, if I do my card just shuts off. Is this because the VRMs are overheating?

Not to sure. The most I've put my Vcore to was 1.15.

Awesome, Got my XFX 5870 non-ref to 935/1275 stable in 3dmark, 950/1300 stable in Kombustor

people have always said the lack of voltage control on non-reference models is a hardware limitation. obviously, with sapphire trixx's ability to control voltage, what was the limitation then?

I'm thinking that the vendors used a different vreg controller (that might be cheaper, or just so that programs like MSI afterburner couldn't control it) than the ref designs did..... either that or its some kind of bios level control lock they put on it. Im guessing vendors did this to limit how many cards they would have to replace due to overclocking (without being able to controll the voltage you can't get as high and there is less risk of damaging the card) but sapphire though differently....

Too bad it doesn't work for my 4870. It's so cool it's begging to be overvolted.
