Highest recommended voltage for Radeon 9700??

What do you guys recommend the highest agp voltage for a 9700?

It seems as though my vidcard is what is holding me back because my system only crashes in 3d tasks.
 
Im not sure what the highest voltage is
but it could be that the agp bus is too high for the vid card. Is it locked?
it could also just be the cpu heating up as 3d tasks are also cpu intensive
 
I have the pci/agp locked at 33/66 and I dont think heat is a problem because I have a MCX4000 with a tornado on my P4 2.8. I can boot into windows and do stuff just fine at up to 3.36GHz but games crash at anything higher than 3.00. I have an Asus P4PE with 512MB of XMS 3200 memory @ 2-3-3.

My vcore has to be set to 1.75v @ 3.36. I think its too high myself.
I want to run it at 3.25 or so because it will do it @ 1.6v

I have set the vdimm to the highest setting @ 2.9v and whatever is the highest agp voltage on my board.

Also changed mem timings to no avail.

My main prob is if I can boot into windows and do everything except play games (even non-3d benchmarking) I should be able to somehow get it stable in games too.

Any help would be greatly appreciated!
 
Watch out for your video card voltage. Your card could be getting too hot and that will make it unstable. It shouldn't need more voltage if it isn't overclocked. If it is overclocked you need very good cooling if you want to raise the voltage to it.
Like the other guy said, it could be a psu issue. Memory timings or fsb that's too much for the memory can cause the problem you are having. So can an unstable cpu. You may need more voltage or less overclocking. If you get your voltage as high as you are comfortable with and still are unstable, reduce the overclock bit by bit until you are stable.
I can run Prime95 overnight and 3dMark at 1.75 vcore but need 1.775 to never crash in UT2003. Games are what really put a system to the test.
 
Well, considering there is a stickied post at Rage3D for R9700pro troubleshooting that says try 1.7V, I would say that is the highest recommended voltage.

Btw, it goes further to suggest 1.8V if your mobo supports it.
 
My AGP is 1.50v

If you look at my system specs ... my AGP bus is 94fsb ... my core is 360 and mem is 340

no need for more voltage ,, as I am stable...

But .. my BIOS has no option for AGP voltage...

Is there a tool for me to up the voltage?
 
Chizow - I'm glad you mentioned what you read at Rage3d about agp voltage. I did some research at xtremesystems. People there are saying that a video card uses 1.5V regardless of how much voltage goes to the agp. Setting voltage higher allows sufficient voltage to always be there when the current fluctuates.
So I raised my agp to 1.7V and have found I can increase my agp frequency and keep stability.

Jump that PCI/AGP lock to 34/68. Seems that alot of times 33/66 doesn't end up locking, which is the case on my 8inxp.

Thx... I'll try that.

Also just noticed that the overvolt on my board goes to normal (whatever it is supposed to be) when it is under load. The vcore I mean.

Usually it is .5v to .75v overvolt, but for example in the bios I have it set at 1.6v and in asus probe sitting idle it says the vcore is ~1.68, but when I put it under load it says ~1.58 to ~1.6.

Is this cause for concern?
