Need Some Serious Help For OC My Graphic Card !

[PX7800GT]

Hi Boys , Listen I Want To OverClock My Graphic Card From 400/1000 To 450/1100 and Have Some Serious Question :
1- First Of all Should I Change any Voltage ?? I Mean , Like OC CPU , Should I Change The PCI-E Voltage Or Something ?
2- Wich Program Should I Use and Its Best For OverClocking ?
3- Will These New Setting Shorten The Life Time Of My Graphic Card ? If It Does Why XFX 7800GT Starts at 450/1050 ? (They Have The Same Cooling Solution )
*My GPU Temp is 50 (idle) and 69 at Max Load
I Will Be Thankful For Any Help :twisted:

No, don't tweak voltage. You shouldn't need it for something so moderate! Also, life of the component will only decrease if you allow it to overheat or idle at high temperatures.
Go download RivaTuner. It will let you overclock as far as it sees safe. I would personally not advise going over those temperatures much, that is really pushing it with 51 idle. The XFX card is starting at a higher clock speed because XFX just wants it to. They set the card's BIOS to naturally run faster to save the user time and pain in his ass. It isn't to say yours can't, it's just to say they wanted to. You should see my friend's EVGA 7800gt, we could hardly get 10 more mhz out of it!
How do you like your Winfast card btw? The 6800gt I got from Leadtek had a cooler than was an absolute abomination on it =/

 

[PX7800GT]

Thanks For The Advices :
So , I Really Like Leadtek , All Of My Previews Cards ( 6800 128Mb,5900 128Mb,Ti 4200 ,... ) Were From Leadtek , I Really Like Leatek ...
OK , So , You Tell Me That I Can Push My WinFast Card A Little Without Being Worry ? :twisted:

 

[PX7800GT]

OK , I Install Riva Tuner 2 ( I Also Have CoolBite 2 )
I Push My Graphic Card From 400/1000 To 450/1100 , Here Are My Benchmarks :
F.E.A.R. 1024x768,4xAA,16xAF Max Quality :
Stock : min=32,Ave=56,Max=133, 30% Between 25 and 45 Frame and 70%,Above 45 Frame
OC (450/1100) : min=35,Ave=62,Max=150 , 17% Between 25 and 45 Frame,83% Above 45 Frame
----
3DMark 2005 , 1024x768 Default :
Stock : 6857 Point
OC (450/1100) : 7600 Point :twisted:
----
The Only Think That Interest Me Is Why The Temp Doestn Change At All ?
Beforce OC , I Got 49 IDLE , 68 Full Load , And Now I Get 50 IDLE , and 69 Full Load !!
OK , Thank You "ak47is1337" and " MadModMike" For Your Helps , Any Other Suggestion ?
Oh , and Another Question Is , I Have Both Coolbite and Riva Tuner , Doest in Make Some Kind Of Confilict ??

When you increase the mhz you will always get an increase in temp, but this is relative to the stress on the sliocon, so in real world will only be a few percent until you get to the point where the chips don't like it and then you will see a reasonable hike in temps (around 10%). This is the point where u back it off. Temp gains in overclocking are normally as a result of increasing the voltage to drive more speed, obviosly this is fairly easy on CPU's, but on a graphics card usually involves some soldering and for most users is beyond what they are prepaired to do or is, frankly, necessary.

A good program to use to check you max capabilities is Aquamark3. Its quite quick to run and shows up artifacts quite clearly when you have pushed the core to far. Great to use if you want to keep increasing by a few mhz at a time. It also tells you when you have pushed the ram to far by locking up totally. This is a fairly solid indicator of a bit too much.

Thak You All Friends ! I Dont Want To Push My Clock Higher Than 450/1100 ( First I Thought About 420/1050 But With The Advices From MadModMike I Changed My Mind ... )
I Play NFS Most Wanted and F.E.A.R. Lots Of Hours With These New Settings , The Only Think That Worried Me is In Morning I Play Most Wanted For a Couple of hours and When I Use ALT+TAB To See The GPU Temp I Say 71c But Fast Decrese To 68c ... !!
So The Question is : Can 70 Degree Harm and Damage My Graphic Card ( With out OC It Never Goes More Than 69c) ??
I Want To Keep My Graphic Card For At Least 2 Years ... I Dont Wanna Blow it ...
So What Should I Do ? is 70c OK ? Should I Decrese the OC ? Should I Completly Disable OC ? What Should I DO ? Help Me Please ...

Any Help ??...

Any Help ??...

Might want to think about either buying an aftermarket fan for your GPU or getting some better air flow inside your case with temps that high. 70c is a bit high for my tastes.

As for the volt mod, I used a program to alter the bios of my 7800GTX and up the voltage via the bios but I don't think my card liked it very much. I got artifacts all over the place when i bumped it from 1.4v to 1.5v (or was it 1.5v to 1.6v, either way).I also raised the stock clock to 520Mhz . Such is life.

Hey ... 70C Is Only 1 Degree C Higher Than My Normal Temp , Do You Really Belive 1c Can Damage My Graphic Crad ??
(Honestly I Dont Think So ...)

Good point, I was thinking about my temps not normal peoples temps (silly water cooling has me all confused)

 

[PX7800GT]

SO ... WHAT ABOUT MY TEMP ??
ahhhh ... I Need Some Profesional Guys ...

Your temps are fine. GPUs normally run in the ranges you've posted. Don't expect your GPU to run as cool as a CPU. If you start getting past 80C, you have cause for concern and may want to consider an aftermarket solution.

 

[PX7800GT]

Yeeeeeeeaaaaaah ... Thank You So Much "Anoobis" , You Save My Life :twisted:
Thats What I Want To Hear ... :twisted:
Finally Some Pro Guys Answered Me ... I Feel Much Better :twisted: :lol:

 

[darkstar782]

GPUs seem to run hotter than CPUs, the thermal throttling temp in alot of the default nVidia BOIS files is around 120 degrees or more.... I wouldnt be to worried about 70 but I'd be contemplating more case fans.

I must say though that a capital letter on every word makes your posts hard to read

If you really want to play it safe, go out and pick up a Zalman V700-CU or an Arctic Cooling Accelero X2.
