But for starters, unlocking overdrive will give you a halfway decent memory overclock, but not much on the core do to no voltage adjustments. It can also give you problems using ATI Tool, so I will not unlock overdrive. I plan on trying the latest Tray Tools first, but hear that ATI Tool beta 16 pre 8 works with it: http://www.techpowerup.com/wizzard/ATITool_0.25b16pre8....
This will give you access to voltage settings, temps, and fan speed control. Without more voltage the core won't go too much higher. But take it slow if you venture down that road. :wink:
Yeah it's fast, just hard not to try and get more out of it. Stock is 625/1800 and some people with that ATI tool beta have gone over 700/2000. But (to the OP) don't expect that on the stock air cooling. Personally, I won't game with it overclocked unless I need a slight boost somewhere's. But I'll feel the need to see what it can do and run a few benchmarks once I get there.
well, based on the TG charts, it doesn't show my model, but it shows the 1950pro.... I am just not impressed with this card because i am skipping duiring FEAR with graphics on LOW. My guess is it's either my Motherboard or Power supply....
Theoretically, the X1950XT wants 30A on the 12V rail. Your PSU provides 28A on the 12V rail, which is slightly under the recommended specs. I'm not sure if this is what is causing the problem, but if you have another box with a better PSU, you might want to test that out to isolate the problem.
What to do if my power supply does not have the 6 pin PCIe plug for connecting to my X1950 XT ?
You are advised to use power supply that have the 6 pin PCIe connector for connecting to X1950XT. Power adapter cable that converts the 4 pin power connector from the power supply to the 6 pin PCIe plug are not recommended. Some power supply without the 6 pin PCIe plug may not have enough current for the 12V rail and the card may behave abnormally especially during 3D gaming. This may include screen corruption, system hang etc.
X1950XT draws a lot of power from 12V. A single card will require 450-Watt power supply or greater with 30 Amps on 12 volt rail recommended (assumes fully loaded system) and for CrossFire™: 550 watt power supply or greater, 38 Amps on 12 volt rail.
I really doubt that two amps is the problem. That quote assumes a 'fully loaded system', and I assume it's calculating the worst case scenario of items drawing from the 12v rail. And then for two cards it says you only need an extra 8 amps? That would suggest the X1950 XT isn't drawing anywhere near 30 amps by itself.
If it was the problem, it'd probably crash, not skip - and only in one game.
I guess he could borrow a friends PSU - if he knows someone with a high end 30+ amp supply - but I really doubt its the culprit.
