Hi all .

I just was curious how ppl were getting on with their GTX285's....

I was hoping that they would be voltage adjustable via Rivatuner like several other cards have been found to be over the last week or two but it turns out things are not so simple.

Hopefully it is just a case of finding the right register to write to but things have scaled down from the 280's 4 voltage state registers to just 2. Whether other registers can be opened up to increase the range is at the moment unknown (well at least it is by me!) but right now it seems all 285's have a max voltage of 1.15 before you break out the soldering kits (it was 1.1875 in the 280) so lets see how we get on with these limitations....

I was initially going to fork out for an EVGA SSC but I had a feeling that most of these cards would clock more or less the same so I could not justify paying almost £100 more for a card that might be already maxed out so I settled for a Zotac AMP! edition which arrived today...

First thing I did was back up the bios but I was very reluctant to flash anything without checking its integrity with Nibitor. The latest available version 4.8 does not support the 285/95 series yet so I was stuck with Zotac's own "Firestorm" tool which provides all the basics: Core / Shader / Ram and Fan speed sliders.

Having read reports of ludicrous clocks I was tempted to go for broke but have decided to take it relatively easy for now.

I have just finished a 3 hour gaming session at 720 / 1620 / 2772 and all was perfectly stable / artifract free so I am going to eventually go for more but at this speed I can finally do rediculous things like play Crysis Warhead and 2560x1600 with all detail maxed out (DX9).

I was also supplied with an evaluation copy of Nibitor 4.9 to test and can happily report that it works flawlessly...

How is everybody else getting on?
