Radeon 7750 Performance/Benchmarks and MI-008 ITX case Build Log - Page 5

post #41 of 77
Thread Starter 
I want to be clear, it's not crashing, I just get those horizontal purple lines for a tenth of a second every once in a while in Black OPs only.

I don't think drivers would cause an issue like that.

I thought there might be interference somewhere. I did route the power switch, reset switch, etc. cable under the motherboard and I'm wondering if that would cause some unneeded interference?

Other than that I'm stumped.

I will try underclocking the vram/core clock on the gpu next.

what does your GPU Usage look like when you experience this?
does this artifacting occur in different titles as well?

interference would imply an analog signal.
are you using VGA?
otherwise, interference shouldn't be a possibility.
regardless, most VGA cable are shielded quite sufficiently, and the artifacting you're experiencing looks anything but fuzzy.

I tried downclocking the vram from 1125 to 800 and the gpu from 800 to 650. Still getting artifacts...but I'm noticing them in all games now.

Afterburner won't let me control the voltage on this card so I couldn't try that.

But I'm getting the card replaced from powercolor.

sounds solid.

keep us updated.



PS: how are you liking your ST45SF?

Seems like a solid power supply. A lot weightier than the stock Apex 250 watt power supply. I have also noticed that the st45sf seems to stay cool to the touch where as the stock apex psu seemed to get a bit hot to the touch at times. Seems like a good upgrade especially if I decide to get a beefier graphics card down the road. A bit pricey, it was 53.99 after $10 rebate on amazon.

awesome.

yeah, i believe that this model's probably really worth it's weight.
it's form factor vs. wattage implies a very high density of high quality components, and reviews have shown that it's capable of sustaining 500W+ of load stably.

that in addition to its efficiency:
i think a price of 60$ is pretty fair in comparison to how it fairs with the rest of the market.

glad to know you can attest to its quality.
not surprised at all that it's literally cool to the touch considering that you're using up like a third of it's rated max tongue.gif
now if only it had shorter cables...

Well it appears that it's drivers after all. The 12.3 drivers are just creating a mess of things with the Radeon 7750 it would seem. After a lot of testing with the older 12.2 drivers again the problem seems to have gone away.

Well at least I hope it's just drivers. So any way, can't fault Powercolor here.

The Silverstone power supply seems to have failed. Tried powering on the PC today and it was a no go. Hooked up the stock PSU and it powers up fine. Not sure what happened, but looks like the Silverstone is defective. Amazon will provide a full refund however. I'm sure this PSU is good, I think I just got unlucky here. Been having bad luck with this build so far redface.gif

Ran Metro 2033 and measured power consumption / temps too:



So about 52 watts idle, 110-115 watts load in metro 2033. Temps seems fine, though gpu gets in high 60s and low 70s for extended hours of gameplay. Cpu gets in the mid fifties during gameplay.

Assuming that that Kill-A-Watt is at the wall,
You're actual power supply is using even less than the actual number being displayed.

Considering that the ST45SF is an 80+ unit rated at 450W.
You're likely about 90% efficient (totally guessing there) at such a low load, meaning that you're entire system is probably only using about 100W during gaming load.

So amazing.
P.S: I dig the candle light.
