Is it dangerous to "Double O/C" a GF3?

[Caveman]

Lets say one pushes up the FSB in the bios on an Athlon XP to 150 MHz...

Does this new speed effectively overclock the Vid card too so as to increase the clock on the vid card? ie... if one were to O/C the already overclocked vid card, would the result fry the card that much more quickly? All things being equal, is the vid card core and memory overclocking independent of the MoBo???

Any good guide for O/Cing the Geforce 3?

Overclocking the FSB has nothing to do with the graphics card. It only generates more heat.

It will o/c the AGP bus speed, but won't effect the core or memory settings of the video card. Just use a little caution when overclocking the video card; use small adjustments until you get a stable speed. You'll know you're pushing it too hard if it locks up or you start seeing artifacts (usually white dots)when playing games. The AGP bus, if pushed too much, can also cause lockups and/or strange artifacting (corrupt looking textures) in games.

I had a Voodoo 3 in a BX133 setup running 89 MHz AGP. The V3 would run just fine @ 183 MHz or higher (166 is stock) when the AGP was @ 66 MHz. With the AGP @ 89 MHz, I could only get it to 178 without it locking up. A 150 FSB is 75 AGP, not so far out of spec. I run my PIII system 150 FSB with a GF3 now. I never really tried to see if 66 Vs 75 AGP affects how far I can clock the card.

I guess I'm asking the same question in a different way. On a CUSL-2C, I was running a PIII 1Ghz O/C to 1200. Everything was fine with the GeForce2 GTS card, no problems, stable as a house. So I bought a Gainward Cardexpert GeForce 3 card, and it installed fine, no problems. However, as soon as I tried to play a game, watch a DVD, the entire system locked up. After screwing around with drivers for much of a day, I reset the machine to the default 133 MHz FSB and the card worked perfectly.
On another machine, running a PIII 500E O/C'd to 750@150 FSB a V770 was working perfectly. I bought a new GeForce III/Ti500 Inno 3D card and same exact behavior. Fine in desktop, as soon as I tried 3D calls, machine locks up. Both running latest DirectX 8 in Windows 2000. Very disappointing. I don't think it's a heat issue, as the cases are well cooled and the crash is instantaneous, rather than after a few cycles of 3D processing.

In neither case was the GeForce III card overclocked using a graphic card o/cing utility. Simply the AGP bus must be clocked too fast for the card to tolerate. I've seen tests in magazines of P4 boards overclocked successfully with GeFIII cards, so my question remains, is this an ASUS issue, a CUSL-2 issue or a GeForceIII issue and can it be resolved?

 

[oldfart]

So you were running a 160 MHz FSB? The answer to your problem is HERE for the CUSL2. Works like a charm.

Old Fart,
Thanks, but I am already running the 1009 BIOS. What is this tweaker utility going to do for my GeForce card to enable it to run Direct 3D acceleration while overclocked? I can boot into my desktop fine, but when I run the Directx diagnostics, the Direct 3D accel is "not available" and if I try to use it, the computer freezes if the FSB is overclocked at all. Works just fine at default FSB, only problem is when overclocked. It's kind of frustrating after running at 1200 for so long with the GeForce2 GTS card without problem to put in a newer card and not be able to overclock anymore. What's going on???

 

[oldfart]

Is it the X86-secret hacked bios? My GF3 CUSL2 PIII 1G would do the exact same thing. Work fine until 3D app which would freeze. The X86 bios fixes it.

 

[Marine]

Old Fart,
No, it's just the standard 1009.bin for the CUSL-2C from the Asus web site. What is the x86 BIOS and where do I get it? I didn't see anything with that name on the link you provided. Thanks

 

[oldfart]

Look at the bottom of the page I linked. Download the bios for your mobo. You can choose from "Evil Inside" or standard energy logo. You enable the hack by turning on the boot virus option. I use the 1011 Beta 004 version. Trust me, it works.

Old Fart,
Help!!! I did as you suggest and downloaded the BIOS. I unzipped it and used the Asus utility to flash my BIOS. The utility verified it was OK and flashed OK. But when I rebooted, I got the "Evil Inside" logo and then the bios ran through the SCSI luns and the PCI device listing. then I got four new strings of text:

AGP 4X Enabled
CPC Mask Disabled
DCT set to 5,7
SM Always Bypass Enabled

then there is a string of text that says, "Come to www.x86-secret to get the latest version.

then I have a blinking cursor. Period It won't boot into Windows, won't do anything. Totally locked up. What happened and what can I do? Are there some CMOS settings I need to tweak? HELP!!! This is my old machine I'm using, but I need my good machine to work!!! HELP!!!

 

[oldfart]

You sure you got the right one? You have a CUSL2-C with or without audio? Which one did you download? I've used each version and never had a problem with any of them. The screens that you see are normal. Try going to default bios settings, then tweak from there.

EDIT


<< DCT set to 5,7 >>


That setting is too aggressive!!! Set your ram timings to 7T, 9T not 5T, 7T in the advanced chipset menu.

 

[Marine]

Old Fart,
Yes, I downloaded the right BIOS for the CUSL-2C w/o audio. OK, I rebooted and reset to 7,9. Now, I only have three lines of text after the PCI device listings:
AGP 4X enabled
CPC Mask Disabled
SM Always Bypass Enabled

"Come to x86-secret.com to get the latest version"

Then I have a blinking cursor. It won't go into Windows. I'm stuck. I think my BIOS is hosed. What should I do? I don't blame you, I'm the one who did the download. The ASUS flash utility said it matches and it flashed OK. I just can't get into windows. Any suggestions?
HELP!! This is on my old slow machine. I need my good machine to work!!

[oldfart]

Odd. Dont know. Flash it back to the normal bios I guess. Are you setting it up overclocked or normal? You can also try turning off the boot virus option which will disable the hack. I wish there was an easy way to print out bios options to compare.

 

[Marine]

Sorry for the repeat posts. Everytime I hit the refresh button hoping to hear from Old Fart, apparently OE sent my post again. Regrets. Old Fart, are you still with me? Any suggestions? My computer is really hosed. I can't even restart it from the blinking cursor which follows the x86-secret.com line with Alt-Cntrl-Del. I have to actually power down the machine and then restart it...which tells me the BIOS isn't happy at all. Hoping you will have a good idea to fix this, I remain, yours faithfully, a simple Marine.

 

[oldfart]

You aren't hosed. If you had no bios, you would be. Flash back to the normal 1009 bios and see what happens.

 

[Marine]

Yes, I set everything to default. Still no joy. Did you say to disable virus checking?

 

[oldfart]

With that hacked bios, the virus option is used to turn the hack on and off instead of the normal anti virus function. Turn it off and see what happens.

 

[Marine]

OK, with the virus check in BIOS turned off I booted right into Win 2K, no problem. So, now I can flash back to 1009 if I want, but this still leaves me with the original problem, Old Fart, how to make my GeForce3 card run Direct3D with an overclocked FSB. One of your original posts said you had had this same problem and that the x86-secret BIOS had fixed it, or at least that's what I remember your post saying. Is that correct? You flashed your own BIOS with an x86-secret BIOS and then your GeForce3 card would work in D3D even while the bus was overclocked? Am I copying this correctly? Thanks very much for telling me to disable the boot virus checker. I was beginning to think I was going to have to find a new BIOS chip!

 

[oldfart]

Yup. If I go over 140 FSB with a normal bios, my system will lock when I run a 3D app with my GF3. With the hacked bios, I can run 160 FSB, 1.2 GHz no problem. My nic doesn't like 40 MHz PCI so I run 150 FSB, 1.13 GHz. Are you BIOS flashing in Windows? I always do it from a boot floppy. Dont know why it doesn't work with your system. Maybe email the X86-Secret guys and see if they have any ideas.

 

[Marine]

Well, after a couple very interesting hours, at least I'm back where I started from. My only regret is that my seven year old daughter found me prostrate on the deck banging my forehead into the cement in frustration about an hour ago. Well, pain builds character as we've all been reminded of lately. I have a functioning computer and I can continue to search for the secret to successfully integrating a GeForce3 card into an overclocked computer. Appreciate the patience of the Mods and all while I worked through this evolution.
And again, if anyone has any good ideas to make my GeForce3 cards run above 133 MHz, I'd sure like to hear from you. Best to all and Semper fidelis! God bless America

 

[oldfart]

Wish it would have worked for you. Do you only get the problem above 140 FSB?
