The Official Graphics Card and PC gaming Thread

I don't know what that means - it's a toughpower 750 - thermaltake I think. Oh, google shows me cwt is a psu manufacturer - which thermaltake rebrands??? On an article comment a guy said "stay away from thermaltake's non-cwt psus." So, I guess CWT is good - why?

Back to DXR:

Wow! I'm spending some more time with DXR's monitor calibration link - the guy who put that together knows his stuff. He's got some similar gamma charts, except that unlike the nvidia control panel, he doesn't have a way to allow me to adjust my gamma on the spot. Again all of this makes me very curious to dive back into the Catalyst Control Center and see how much fine-tuning they give me to adjust monitor settings.

I will never take monitor settings for granted again - over the last week my eyes have been opened, as you guys have seen with me running around screaming "WAW has the greatest graphics I have ever seen!!" Hahahaha.

Rich

 

Yep, same unit I had, and it's built by CWT - the red inductor covers is the giveaway

 

haha - okay good, your old psu, lol.

Hey, my fan in back is an antec, and I see at newegg, they mention three different rpms, so mine must be the 2000 rpm version, 79cfm, if it puts out more slightly more air than my 1900 rpm scythe.

More and more I'm thinking that the ultra kaze, at 3000 rpm, 45 db, and 133 cfm, is the very least powerful fan I should be considering. By the way, I will put a controller on it. I have a controller left over from the zalman vf1000 3850 cooler that Jeff talked me into getting, and the ribbon cable will fit around the kama bay and allow me to silicon the controller on top of the case on the few occasions when I'm sitting sideways on a little chair that I keep for that purpose, and doing something with the cpu besides gaming.

I have decided that silicone is the only thing that will allow me to mod that loaner case, in a way that later on, if I have to, I can remove the silicone and nobody will know the difference. I'll post later or tomorrow my whole plan of attack on mounting the kama bay - with a good deal of silicone.

Question: Are you sure, sam, that a usb optical drive will let me start my games? I tried it on a network mapped optical, and even though I was able to change all the nodrivetypeautorun registry entries to 85 instead of 91 or 95, to allow autostart off network drives, and I did get autostart running, as soon as the game autostarted, and I pressed Go, it said the disk was not in the optical drive.

So, maybe the game software is clever enough to recognize a network mapped drive - but am I going to have the same problem with a usb drive? Will the game treat that differently than drive Z through the network? How does the game know the one drive is on a network, and the other is through the usb port, or through the ide controller. Well, I guess the computer tells it, lol.

Anyway, I am on the verge of ordering the kaze. I also happen to have a couple extra 40mm fans lying around that I will silicone to the outside back of the case where that vertical venting is, to help pull the air through that the kaze sends hurtling down from above, lol.

Rich

 

2000rpm is fairly typical, that's what my Nine Hundred's stock fans were.
A 3000rpm would be OK, but no more, otherwise it's completely pointless. Care with a big fan like that on a cheap controller, it will probably melt it.

 

so long as you setup can pull more air out faster than it can put in i see no problem with high powered fans.

i miss those delta airline fans.

Exactly, and he's putting more air in than is going out, hence the problem

 

That delta video was awesome! Hahaha.

I was seriously considering a delta - not the 220cfm 65db 4500 rpm super monster, but a 150cfm 3200 rpm 53db semi monster, at 1 amp. But I googled it, and read some scary reviews about very irritating clicking noises.

Meanwhile, over at newegg, they are out of stock on the ultra kaze, but google pulled up a newegg link, and there are 100s of reviews, and not that bad either. The kaze pulls 133 cfm, at 3000 rpm, 45db, 0.6amp - the delta was actually doing better in regard to cfm per revolution, but look at the power draw - fan blades must be way deeper on the delta - it's pulling 66% more power, for 7 more dba, only 7% higher rpm, and 12% more cfm. Overall the kaze seems like a nicer mix of minimal power draw, good cfm, not too bad of noise, reasonable rpm.

Anyway, I ordered the kaze from ebay - about $15 delivered with tax.

Now, in regard to pushing more air in, than I am pulling out - THAT'S EXACTLY WHAT I WANT. LOL

I don't want dust in the case, therefore I need positive case pressure, so I have to have more push into the case, than pull out of the case. The kama bay will have a front fan filter, and remember, that's my one and only fresh air inlet.

When I post the pictures, later today or tomorrow, I think that will explain things fairly well.

By the way, are you guys sure the usb optical will let me start my games? I found one for $25 on ebay.

Rich

 

your always going to have dust in your case..there is no way around it...unless tomorrow all the dust in the world disappears...your wasting your money by what your doing. get a high DPI mouse 800 or 1000 will do you. also make sure you set your polling rate to at least 500Mhz

 

What do you mean about USB optical Rich? If you mean an external USB optical drive, most current motherboards will boot off a usb optical drive. If I'm not mistaken :S
Windows will do anything with a USB Optical drive. I run one... Probably my 2nd favorite as a matter of fact

 

Rich: Delta fans are hideously loud, not just because they're so fast, but even when you slow them right down, the mechanics are geared for ultimate speed, so the mechanical clicks/buzzes they make are infuriating.
The Ultra Kaze suffers the exact same problems, and is why it got a very poor review on SilentPCreview. It's loud even when it's pushing so little air it may as well be off.
A 3000rpm Ultra Kaze pushes 107CFM at 47dB, at a 2760rpm rotation speed. At the full 3000 you're probably looking at around 115-118CFM at around 50dB.
A 1900rpm SlipStream like I use pushes 79CFM at 39dB, at a 1780rpm rotation speed. At the full 1900 it'll be more like 85CFM at around 42dB.

Here's what the slipstream sounds like: http://www.silentpcreview.com/files/sounds/fans/scythe-ss-sh-1m.mp3
Now here's what the Ultra Kaze sounds like: http://www.silentpcreview.com/files/sounds/fans/scythe-ultrakazeh-1m.mp3

No, it's not what you want. DXR is right, more air in than out is pretty pointless.

 

Yeah more exhaust is what you want. Positive pressure keep stale, warm air in the case and leads to heat buildup. Negative pressure ie a vacuum will remove hot air from the case and thus prevent any heat build up at all. If you feel the air from a case with positive pressure it will almost always be warm because there is warm air sitting in the case waiting to be exhausted. On a case with negative pressure it will almost always feel cooler because the hot air is always being exhausted. I had this explained to me in detail in a class iirc. The more air you exhaust the better. If you don't like dust you should use canned air or an air compressor. Performance PCs need to be maintained regularly anyway so giving yourself a false sense of security by keeping dust down may lead to issues escaping you until they cause damage. Finding a case with dust filters helps as well. The HAF could certainly use them...

 

I should calculate how my secondaries pressure is. It'd be interesting to see how I could improve upon it, if at all I really don't think that case can handle much more modification LOL!

 

As you can see in the picture, I can't manually adjust the fan speed on my 5850 anymore; anyone know what might be the problem?

btw is there anywhere else I can d/l ati drivers, it doesn't look official server works for me anymore.

 

You've unticked Enable ATI Overdrive!

 

Oh man, didn't even notice that checkbox *headdesk* Thanks sam, everything 'works' again >_>

 

Has anyone done any Benches on GFX cards with there audio properties Enabled by audio receiver has an HDMI in, and drool at the fact i could be getting uncompressed master streams. thing is my Current audio setup is very good, with very many cables.


my cat got lost in those wires...True story.

 

I thought Graphics card HDMI outputs just transmitted audio from your PC's sound card?

 

AFAIK yeah it uses audio from your sound card. Not been able to try it but there are no actual audio drivers for the HDMI ports. It only makes the link from your PC's sound processor to the HDMI cable.

 

http://www.amd.com/us/products/desk...5770/Pages/ati-radeon-hd-5770-overview.aspx#2

it says it has its own integrated audio.

 

AFAIK that's only a passthrough chip to convert the analog signal to HDMI. Having used HDMI myself I can confirm that changing options in the Creative control panel for my sound card has an effect on HDMI output. So I would guess that it's only passing through your PC's default audio signal.
