7800gtx overclocking help

[pcpbit]

Just got my card and i was wondering if anyone has some tips on oc'ing this thing. I know so far it doesn't make a huge difference in FPS, but i still want to. Also is their a temp monitor for geforce that i can see in my systray?

[Angry_Games]

download a reg hack called 'coolbits'

 

and run the auto overclocking feature in it (the nvidia control panel for your vid card)

All the info you need to monitor temps:

Thanks Angry. I have already done that... i was wondering if there was another approach. Do you guys know exactly how it determines the OC? I used ATItool previously for my X800XL and i thought it was great how it tested for artifacts.

 

Thanks pickles... i was going to set that up before but i never got around to it.

I cant get the Overclock settings to stay. I check the box "Apply These Settings on Startup" after i specify the settings, and i have to change them back after every reset. Anyone got a fix for this problem? Latest Available drivers and Coolbits2.

I havet had any problems hit test settings apply settings and click the box to apply at start up.

 

Not for much higher settings than mny of these cards you will need aftermarket cooling.

 

 

Coolbits is really all you need though the ATI tool was nice.

Has anyone heard anything about the new Dell 7800GTX cards? they have heatpipes and look like they would cool pretty good. I can't find any stats on them if they are Clocked at 430, 450, or higher?? Here is a pic of them. http://www.extremetech.com/image_popup/0,1...d=111318,00.asp

I personally won't touch coolbits with a ten foot poll :.

 

I use rivatuner, abiet even the software based oc'ing based apong nv's coolbit cpl panel, as long as I don't use the buggy nv cpl for it lol .

 

Auto oc'ing may or not work out.

I dn.

I do know that depending on teh video card bios it can have trouble when it actually hits an error and detects it, for clock slowdown.

 

Clock slow down is built in both the video card bios somewhat (where I dn know because the regs are newer, older regs for it are not set for core slowdown ^^) and the drivers.

Anyways it'll totally hitch up the video card real bad if it detects an error.

You may or may not see an error in your logs saying stress test L0->l2, or one just like it, there are many types.

 

On the newer rev roms it's not a huge deal when it happens though.

 

 

Totally watch out for mis matched mem clocks of 2d and 3d.

This is a big issue, maybe it's not the newer rev's at all that fix this because I tossed the ability in my bios to have seperate clocks, I dn blah .

I reccomend if you got seprate clocks is not to touch the 2d clock at all unless you doit by hardware, and or have experience with it allready on how far the 2d core clock can go.

Don't touch the mem clock for 2d is what I mean.

 

I dn anything about the idle clock, matter of fact there is 4 or 5 possible performance levels, being 3d, 2d and idle, the rest are never setup from a default bios, so I dn what they could be setup to be used for.

 

 

For testing I reccomend these:

Core:, 3dmark03 gt1 and gt4.

Loop test 1 - 3 times at the higest res you are willing to deal with, ie either decent refresh rate or just plain old 1024x76, make it bigger then 640x480 though for sure.

If it locks up breifly hurry up and start hammering on the escape key, as soon as it resumes it'll hitch right up again if you don't exit it asap.

 

Use test 4 to finilize it, I dn even use test 1 anymore really but it worked great for my quadro4 card.

 

Memory:

The best tests so far I've com saccros is doom3, and hardware accelarated video playback, using either nero's decoder (somewhat hardware based if you got it if you can beleive it ), or nv's decoder.

Look for tiny white dots, pixal size, maybe this depends on how you got video playback on your rig setup though.

 

In doom3 look for black dots, or white dots, or bad triangle things, which will be black probably.

This could be on anythign from the guns, to your hands, to the floor, the windows, etc, look hard for a few mins each mhz step you take!

 

 

Oh and also core on doom3, look in the walls, behind bars in such, and on the sinks in the bathrooms, stuff liek that.

You will see a blue color, that's corruption.

Something I forgot about lol.

If 3dmark fails to find a rpbo, this may find one .

 

 

Allways check your logs, then again I dn but I believe most of the newer errors are automaticly in the logs even if you don't have some of the debugging logs enabled.

 

When you goto a buddies house re-check EVERYTHING!

This goes from the mobo it's self to the video card.

That way you can have something setup for yourself mobo wise if it's to hot over your bud's house.

 

 

Card temps...

You may not have this ability, then again you might.

Rivatuner has the ability to check up on this, the voltage lv's are complete bs in that prog though but at least it can tell you your temps .

If this is'nt happening then you will have to mod the video card bios to enable the temp thingy or thingys.

I dn reccomend doing this to anyone unless thaey have some decent prior experience with this sort of thing.

 

The days of using vgabios to test the bios before flashing it is over.

It does'nt work anymore, so it's all or nothing in one shot, if you mess up you might never recover it again you know?

 

 

Edit:

Absolutly do not oc the core without redoing the gel on it.

you can oc the mem np really, does'nt matter if they put some lame heatsink of them or not.

But the core, you shoudl'nt oc it wihtout redoing that, it'll start getting really really bad if you do, ie stocks clocks go bye bye lol.

[peanutplanters]

if i use coolbits, it auto dectets at 1.35/490 but it gives me corruption in cs:s, even though my temps arent THAT high. i had to lower it to 1.35/480 =/

[Trevor]

Btw you can still check for artifacts on an nvidia card with atitool.

 

Edit: lol

With every geforce ive had (ti4200, 6600GT, 7800GT, and an older one), when using the coolbits to auto-overclock....I always have to back it down just a little to be stable in all the games I play. And don't oc the 2d, only the 3d. There's nothing to gain in 2d, and it will just bring heat. Don't know why anyone would do this, or why coolbits even puts it in there.

I guess that is one advantage of the ATI tool it heated up the video card so it was a better test of stable settings. I can usually go higher that the auto overclock with good coling. The nvidia Luna Demo is a fast way to test for artifavt at least on my cards. One great thing about watercooling is you dont need to worry about heat anymore. Having the 2d and 3d at the same clock rate was more stable on my older cards.
