What's the default AGP Voltage, for a 8X AGP Video Card? HELP!!

thatsright

I ask as I'm trying to OC my P4c 2.4G and Kingston Hyper X PC3500 512 X2. I have the PowerColor 9700 Non-Pro Evil Commander Gold Edition, yet I'm not sure if in my IC7 BIOS, the AGP Voltage is right. Now its set to 1.55V. I am running the ATI's Catalyst drivers ver. 3.4 that I downloaded from ATI; for their 'Built By ATI' Radeon 9700 Pro card.

Yet my CPU Overclocking is just not working while I run Prime95 & 3dMark2001SE Demo with sound on, together. The demo will either crash on me, or the PC will just do a reboot without any BSOD or error messages?

SO, is 1.55V the right voltage for the Card? I'm just suspecting that the card might be the problem. BTW, When I try to O'C the CPU, I have AGP/PCI ratio Fixed, and the Video Card is running at stock speeds, no tweaks or anything.

Thanks
 
Can anyone help me here, I'm desperate. The AGP Voltages in the MB BIOS are 1.50, 1.55, 1.60, 1.65. But this is a AGP 8X Card. yet their is NO 0.8V option for the AGP Setting in the IC7 1.13Bios.

Can anyone think of a fix for this?

Thanks

Uh, WTF? Default AGP voltage = 1.50V, and don't screw with it. 😛

What's your CPU cooling setup?

Uhh I think I left out that for the last 10 days, my AGP Voltage has been running at 1.55V. But this Radeon 9700 is a 8X card, so shouldn't there be an option in the AGP Voltage for like 0.8V???? I've been trying to O'C my CPU all morning, and it would just crash, as earlier I could run SETI@Home & Folding@Home simultaneously for like an hour, and no lockups when running the FSB@274. But if I then run Prime 95 AND 3dMark2001SE together it locks up after a few minutes, or my PC will just restart itself in the middle of the 3dMark2001SE Demo??

I have a Zalman 7000AlCu, AS3, 1 80mm Intake fan on low setting, 1 (of two) Antec rear 80mm case fans and 1 Side Antec 80mm Fan blowing over the AGP/CPU area. It seems like my max CPU temps that are reported by Hwdoctor is about 64C. This is running @ 1.525Vcore, Vdimm 2.8, HyperX @ CAS 2-3-2-5. In the Bios, I have System BIOS Cacheable? set to Disable. Video Bios Cacheable is also set to disable.
 
theres 2 voltages. 0.8 - agp voltage, and the 1.5 is VDDQ AgP voltage or some shite. Usually, the 0.8 is unavailable to tinker with, so that users wont burn tyher crap, and RMA it.
 
Well yeah, 0.8V doesn't even show up in the BIOS as a option. But 1.5V & 1.55 do? Which one should I select if I have a AGP8X card though??
 
Ok Does anyone else know for sure what I should set the AGP Voltage in my MB BIOS too?

I tried emailing PowerColor, but I haven't gotten a respone, and I called ABIT and they suggested trying to run the Card in AGP 4X Mode, but I paid for a 8X card and thats what I would like to try.

Can ANYONE Help out there, please I know I sound pathetic, but I don't care; I need a definite answer on this.

Thanks

Well right now the FSB is @274= CPU of 3.293Ghz. I'm running the ABIT IC7 Bios 1.13 and unfortunatly, I've had to run in Single Channel DDR Mode while I wait for a replacement DDR Stick from Kingston. So all the whil running these tests were on a single HyperX PC3500 512MB Module.

How does this alter the 'mix.' Thanks
 
does the power color radeon 9700 card run stable at stock cpu and stock video card settings (without anything in system overclocked)?
 
Yes, from all I can remember. Though I haven't tried to run any 3D benchmarks or Demos while using the new 1.50 AGP Voltage, either at the stock speeds, or overclocked.
 
usua;;y when the FSB is overclocked, you cant lock the VGA at highest AGP multiple...but, needless to say, none of the systems out there can (even in theory) use AGP 8x. They barely use AGP 4x. AGP 8x is just marketing, so that the users'll think they're gettin something super-fast...i wouldnt pay to much attention to it, if i were you. You aint gonna see NO performance boost between 4x and 8x...
Dont worry, and dont exploit a perfect card! Our systems can give us only that much performance...
 
So Squidy, to try and resolve my VidCard problem, if thats actually it, and If I want to OC my CPU at around a FSB of 275 or so, should I set my AGP card to 4x? I would really still like to lock the AGP/PCI clock however, as I don't want the PCI bus frequencies to start jumping around. If I do that, then I'm sure I'll start to have endless NEW problems, when I'm just trying to isolate this one.

Thanks

BTW, in case I haven't already said it before, the 9700np IS NOT overclocked, AND I HAVE NO intention of doing so. Right now its still at it's stock speed.
 
The 9700 card are very sensitive to AGP frequency running out of spec. I'm not familiar with your motherboard, but if you can can lock the AGP at 66MHz do it for sure. That could be your problem right there.
Because the 9700 gets its power directly from the psu, there is no advantage to upping the AGP voltage in bios (unlike some GF4's which can benefit).

I am very happy with what I have at the 2.4C level, but why not try to get a bit more juice out of this famously GREAT O'C candidate. And getting the 2.4C up to 3.0Ghz at O'C level is a cinch. I may be trying too much going for something in the 3.2-3.4Ghz Range for O'C, but I will try a few more things and if still, no dice, then I'll start dropping back down to the 3.0-3.2Ghz range. But of course, the #1 Priority is stability, everything else is secondary.

_______________________


A few other things: Yes, I have the AGP/PCI Fixed @ 66/33Mhz. And the 9700 Card is running at default Core/Memory speeds, nothing is O'Ced on the Video Card. But I'm just wondering if the AGP Voltage in the motherboard BIOS running previously @ 1.55V was causing the lockups/reboots? Now Its set to 1.50V and still @ AGP 8X.

Can anyone else think of anything. Thanks
 
The extra voltage you had going to the AGP slot would not cause instability. What happens is the voltage goes to the AGP, but the video card still only pulls 1.5V. The reason people have had good results with extra voltage with GF4 cards is that if there are voltage fluctuations then you are assured of always having at least 1.5V.
I would run memtest86 (not memtest) through ten passes (it'll take awhile) and make sure there are no errors.
Trying out AGP 4X is a good idea. And I think Squidman is right that you will not lose performance.
 
I have run Memtest-86 3.0 on my RAM thru 30 loops, and no errors. What I recently changed though, is I put back two of the Antec 80MM case fans in the case and they are running at Full blast. So now I have two exit fans, one side fan, and a intake. Another thing that has finally seems to bring me success is that now I'm trying to OC at the FSB 270Mhz level. Before I was in the range of 274-284. And I think it was a combo of too much heat, or just that it was too much power required for my Antec True Power 430W? But I still have my doubts about the power not being enough.

Now I just got done running Prime95 & 3DMark2001SE demo loop for about 45 Minutes without any errors. Of course this is no way near the 24 Hours I will soon put it through, but its a lot longer than the 5 or 10 minutes I was getting before when running both of these. Now I will try to put the AGP Voltage back to the 'default' of 1.55 and put one or two of the Antec 80MM fans in silent mode. This will increase temps probably, but I hope not too much? And I get max load temp of 59C when running the two utilities above, and around 42C at idle with the OC speed.

Thanks.
 
When i oc'd my system to 210 (dont go further with 2700 ram) mhz, if i was to lock the agp at 66 the system would end up at either not booting at all, or in continious restart loop. Yes, this VGA IS really sensitive to those specs. I left mine at auto, and was not bothered by it at all.
Pelikan's right. THe power on the mobo is distributed in "less-than" manner, so if you set your AGP to 1,5 - it would get 'round 1,43, and when u set it to 1.55 - to about 1,48. So that shouldnt be a problem (well, VGA producers acvcounted for that as well). So leaving thos voltages at default is highly recommended, as leaving the agp bus at "auto". Because in "mad" overclock, AGP could simply fail to work that way.
As tests concluded - there was no to little difference betweeen AGP 2x and 4x, and no difference between 4 x and 8 x....when the FSB's are like at 1600mhz, and can in theory provide 4.2 gigs r wahtever of info for the vga - then it shall be needed.
Kick ass overclock, by the way.
