Just bought an ASUS 6600 256MB...need driver help

[Greenmachine]

Okay...with aperature size set at 128MB and fast write on there is still some graphical lag. Now I am going to try without fast write.

Typically a big drop in fps is either the CPU or the GPU overheating, but since it's a brand new card I'm not sure what to think. Download speed fan and see what your voltages/speeds and temps are.

 

[Greenmachine]

well I already have ASUS smartdoctor... it says my voltages are:
Vcc = 3.34V
Vcore = 1.32V
FB= 2.68V
Temps:
GPU = 30C
RAM = 35C
Fan = 4559RPM

Engine clock = 300
Memory clock = 500

Do you still need me to download speed fan??

 

[kirock]

Yeah dwnload Speedfan, it should give you more voltages, more temps and maybe the CPU fan speed too. What I see from your list is just the video card stuff. If the CPU overheats or the voltages are dipping during heavy 3d game then you'll experience fps drops.

This is just an idea and I want to make sure we're not "picking" on the new card as the only suspect.

Okay...sorry for the delayed response. I have had a pretty crazy weekend. Speed Fan results are:
Fan 1: 3125RPM
Fan 2: 0RPM
Fan 3: 1671RPM
Fan 1: 4298RPM
Fan 2: 0RPM

Temp1: 26C
Temp2: 31C
Temp3: 5C
Temp: 1C
Temp1: 29C
Temp2: 34C

Vcore1: 1.50V
Vcore2: 2.53V
+3.3V: 3.12V
+5V: 4.14V
+12V: 11.58V
-12V: -3.23V
-5V: -0.23V
+5V: 3.63V
Vbat: 2.85V
+3.3Vcc: 3.34V
+2.02V: 2.02V
+2.5V: 2.40V
Vcore: 1.55V

I don't really know what I am supposed to be looking for. What voltage do you want me to monitor while gaming??

 

[kirock]

+5V: 4.14V
+12V: 11.58V
+5V: 3.63V

Well if these voltages are correct, they indicate a stress on the PSU, especially in the 5 volt rail. The 12 Volts is a little low too. When the voltages are lower then they should be, this means the PC is drawing maximum current for that voltage and the PSU is working at it's limit.
What wattage do you have? Read the numbers off the side label. Should look like this: 3.3V@22A, 5V@30A, 12V@18A (those are the 3 that matter).

[Greenmachine]

Okay the PSU calculator says my total wattage required is 249W. I will check my PSU sticker in a sec....it's a CompUSA 300W PSU.

 

[Greenmachine]

it's a CompUSA 300W ATX PSU
+5: 20A
+12V: 12A
-5V: 0.3A
-12V: 0.5A
+3.3V: 14A
+5VSB: 2.0A
What do you think??

 

[kirock]

Yeah, I think we found the problem. That generic crappy PSU can put out 70% of it's rated power. The power on the label is maximum output for a few minutes. So if you take 300X0.7=210W continuous. You are pushing that poor thing and it will soon just blow-up.

I had a 450W generic crappy that came with my case. I blew it up within a week while playing HL2. I have a 6600GT and an AMD 3500+, one HDd and one DVD/CD R/W, that's it.

Antec, OCZ, Thermaltake are all good manufactures. You should look for a PSU with at least 22A on the 12Volt rail.

Cheers.

 

[Greenmachine]

Thanks...I will buy one over the summer. I have been looking at a few. What do you think about these?
1). Antec Truepower 430W
http://www.newegg.com/Product/Product.asp?Item=N82E16817103928
2). Antec Smartpower 500W
http://www.newegg.com/Product/Product.asp?Item=N82E16817103937
3). FSP 400W
http://www.newegg.com/Product/Product.asp?Item=N82E16817104953

System specs:
Gigabyte GA-K8NS mobo (20-pin main)
Asus N6600 256MB AGP
512MB PC3200 Corsair XMS Pro
Creative Audigy sound
Western Digital 60Gb
cd burner, cd-rom, floppy etc.

 

[Greenmachine]

oh yeah....
AMD Athlon 64 +3000 (2000Mhz) as well
whoops

 

[kirock]

Either one of the Antecs you listed are good. FSP seems a little low on the 5Volt amps (that's the trade off of dropping to 400Watts). Invest in a good PSU and you'll have better performance, more stable system and longer life for it and other components.

Cheers.
