GeForce GTX 550 Ti

post #1 of 9
Thread Starter 
Hello guys!

i just ocd my gtx 550 ti 2gb.though i see some guys clocked their cores at 1010,1100 etc etc, Mine does not.Just weird. even though i overclock it around 1010 or 1003 the benchmarking andf stress testing just reads 999mhz. But if i let it go over 1010 it woulds just show sometime 400mhz or sometimes just 100. SO weird. the temps are good. maximum of 70.thats why im thinking i can still up the clocks but it doesnt.help anyone?

I see 2 possible reasons:  either this is just the way your particular 550 Ti is, or it's the power supply.  The reason why I am partly suspecting the power supply is that it may be one of those PSUs to be avoided if any overclocking is to be done because I've never seen any PSU experts say anything good about Diablotek; only bad things.

BTW, what PSU would you suggest? I just want a cheap one but performs good and is really good. Maybe around 700w?

It's not about the capacity; it's about the PSU's quality of power delivery.  Even a 400-450W power supply would be enough if it's a decent one.  Although, I wouldn't want to recommend that capacity because then making a big upgrade to the video card would be difficult.

 

So, I think a decent ~550W power supply would be better.  One that I can think of off the top of my head is the 550W XFX Pro "Core Edition".  Of course, I realize that it depends on your budget too.

yeah, its because if in the future i want to upgrade, atleast i have enough wattage.
its better to have extra than less. thats kinda good.a cheap one but still has good looks, good wattage and good manufacturer. When i have money i will upgrade sooner.
THANKS!

Ok, sounds good!~  If this Diablotek PSU is as bad as I think it might be, then try to resist overclocking anything until then.  I don't want to see the PSU die and kill something with it.

Yeah, Diablotec is the devil. I had one fry a computer (and the replacement died as soon as I plugged it in).
Do not overclock with that PSU. I personally would not even use it.

How much do you have to spend?
