Radeon X1950 Crashes in IL-2 if AA and AF set to max

[RamsteinUSA]

Hi,
If I set both Anti-Aliasing and Anisotropic Filter to Max IL-2 1946 my computer Crashes and Reboots the computer after a few minutes of playing. If I set those each one notch down, no problems. What is wrong? maybe the latest driver? which 7.4 Catalyst package is from April is the problem? I don't know if this happened with older drivers.

My video Card is Radeon X1950 (HIS Radeon X1950 512MB)

Thanx,

[JG52Uther]

Maybe your computer cannot handle max settings.What is the rest of you system?

I had the AGP version of that card and no problems running it at max. But I was also on the 7.2s. If it isn't driver related I wonder if it's pulling so much power at max and either overheating or your PSU hasn't quite got the juice?

absolutely no overheating... it's very cool....
PSU is new 550Watt Antec with 3 12V rails. and I have monitoring software for voltages and temps...

What are the amps on those 12V rails? Aslo what arethe rest of you system specs.?

Excuse me for riding the coattails of this topic...

...I just upgraded to a X1950 Pro and want to buy a new PSU. I have read a lot of this amps on 12v rails - what on earth does this mean?

Any recommendations for a PSU (450-600 watts) for less than $100 US?

PC power supplies have a couple of different voltages that they supply power at depending on the device in question. Its basically an incremental upgrade over the many years that the typical ATX platform (your average computer case) has been around. Long story short, the more amps per 12V rail the better. Some video cards really draw allot of power on the 12V and its better if your PSU has a higher rating.

My recommendation is the Antec line of power supplies. You can find quite a few of them for cheaper than $100 and they are quite good. EarthWatts or TruPower or anything that they are selling these days should do. Whatever brand you go with ...don't cheap out on the PSU. Make sure its a good one with a good rating and history.

In short, it doesn't mean anything http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

If your PSU is powerful enough, your computer will get the needed amperes from it. If it isn't, well, guess what... http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

You'd only need to take into consideration maximum current transfer (the rail stuff) IF there is a current limiter in the PSU rails other than the physical limit (that's when the lines break from heat), which I guess is well beyond what any computer will be needing.

Just get a powerful PSU (500+watts) and you should be fine, IMO.

Actually, Wattage is less important than Amps. You can have a 600W psu but if it has only 18A on the 12V then you can't run squat, especially if you overclock. On the other hand you can have a high Amp rating on the 12V (say 45+) and most likely be fine with a 450W psu (unless you a running a quad core and one of the newest powerhungry video cards).

Quote: ARE MULTIPLE 12-VOLT RAILS BETTER THAN A SINGLE 12-VOLT RAIL?
With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you'd think it was a better design. Unfortunately, it's not!

Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply's rating. Those losses occur because power literally gets "trapped"� on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system.

Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete.

PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.

Actually, that's completely false, sorry. The only important 2 factors are voltage and power, as simple as that.

And by the way, if you have a 600W power supply with 12 volts, that pretty much defines the maximum current you will be getting: 50 amperes. On the other hand, your 450w psu example is simply NOT possible.

Actually, that's completely false, sorry. The only important 2 factors are voltage and power, as simple as that.

If this is true then why do people have psu's shut down on them because one compnent or another is drawing too many amps? I'm sorry but wattage just isn't that important, one review site (will find link later) did a test with (and this is off the top of my head so don't nail me if I mix one high end component for another) an intel quad core cpu highly overclocked, two 8800GTX's in SLI, four Raptor hdd's, two optical drives, a large amount of case fans and several lights. They ran software to stress all these components simultaniously and they were not able to get the power usage over 600W!!! The amps on the other hand were well over the 18A that most low priced psu's have on the 12V. If that setup can't draw more than 600W then not much else will....

Do you even know what an ampere is? Furthermore... do you know what electric power is?

And last but not least, did you read what I wrote?
