Hey i've been over clocking my graphics card with riva tuner and seem to have difficulty getting over 9% increase without a bunch of artifacts popping up in RFG (green flash every once in a while) any ideas why i can't get any more?:roll:
 
whats the temps/cooling like?
 
oh, how high of a PSU would be good for overclocking this card?
 
My temps for the 9% OC at 100 % Fan Speed and 99% GPU Usage is between 60 and 65 selcius
 
*Celsius.

And those temps are fine, can you post what clocks you've set it to for this 9% overclock? The card might already be factory overclocked, which is why you're not getting as much of a % overclock.

I doubt it'd be your PSU, those Corsair XT models are beasts.
 
With the res of your LCD why are you OCing? The stock 250 should be plenty.
 
Seems more like your CPU. A phenom 9850BE bottlenecks the crap out of a 9800gt.
 
its almost ok mk, explosions in RFG slow it down a bunch, but anyways, here are the standard clocks and the ones its at right now being OC'ed.

Core Default: 738 MHz
Core OC: 805MHz

Memory Default: 1000 MHz
Memory OC: 1088 MHz

Shader Default: 1836 MHz
Shader OC: 2002 MHz


Interesting to note that the memory over clocks better than anything else, and anyhting pass the stated current over clock encures bad artifacts.
 
Oh and zithe, its definately not the CPU it doesn't even go over 50% usage in RFG and none of the cores max out

Do you have a link to the exact video card?
 
I wish I had 2 of those cards. (not exactly helpful but true)
(all I can come up with is its their STD edition and not the Better "Core edition" one with the better memory)

Doesn't mean anything, really. Games can be written to cap CPU usage. I bet you you'd have very noticeable difference if you hit 3GHZ.
 
my card cant oc for crap either man. some cards arer just ocing duds. i bought this corsair psu to see if power was holding me back but my card maxes at 760/1900/1150 before i get artifacts or straight crashing (in furmark)

2000mhz and above is pretty good for a last gen card..

When I OCd my older cards I noticed that I got a lot less perf increase from OCing the GPUs than I did OCing the CPU

Right now I have crazy DDR5 on my 5770s and it dosent seem any better than my 250s were...
 
Problem with the 5770 is that the GDDR5 is on a 128 bit bus, which means its about as fast clock for clock as GDDR3.

OP, you probably do just have a dud card, it wouldn't surprise me with those clocks.

I understand that part, its just people keep saying the 5770 is equal to or better than a 260, honestly I dont notice any dif over the 5770 and the GTS 250s.

And calling the card a "dud" is a bit much. The cards arent sold guaranteeing they will OC so as long as it performs at its advertised spec its a good card to me.

So, whats the verdict on my issue? And i don't plan on getting a new CPU anytime soon i've already OCed my cpu as much as i can with just the signal clock (multipliers are locked)
 
Everywhere i've heard , they say the gts 250 Overclocks well. but i suppose it could be my cpu, although programs rarely use all cores (audio surf uses only 1!) but its getting better, maybe ill look into other am2+ socket CPU's
 
Have you tried it in a different mobo? Not that it's very likely but maybe there's some electrical interference with the frequentcy of some other component.
 
I would like to try that, but i don't have any other pci express mobo's
 
I don't understand the 'get a better CPU' argument here. That argument should be stated if you're not getting the performance out of your card that you should be getting. That has nothing to do with OCing. A weak CPU could never in a hundred years affect your GPU OC.

My verdict is that the OC you have is actually pretty damn good (for core and shaders).
 
mk, guess il accept what i got, im getting sat least 30 fps in new games anyways so.
