Afterburner & GTX460 voltage issue

post #1 of 11
Thread Starter 
I recently bought an MSI N460GTX o.c Ed. Graphics card (O.C edition only because TD actually had it on sale for $10.00 cheaper) and have been playing with the clock speeds with the Afterburner utility it came with. I've stopped at 905mhz on the core clock the mem clock up to 2054mhz. and it seems to be running great at 53 degrees celsius. My question comes in with the voltage control. I have unlocked it by ticking the box "Unlock Voltage Control" but when I try to adjust from the stock voltage of .962mV to .964mV and click apply the meter only drops down to the default voltage? Also I am unsure what it means to "Force constant voltage" I've played with afterburner in the past, but I've never had anything better than a GT430 that takes no extra power. In addition to this being my first post ever on any forum. Sorry if I'm not asking the right questions in the designed place. Thanks in advance

I should add the core clock is 810mhz stock. I've been as high as 940mhz but began to see artifacts so I backed it off to 905 for now. Everything I've read though that this is the time i begin to increase the voltage.

Naahhhh give more the 460 can handle it

Give it 1.087 and put the core up to 950 and men to 2150 u should be good any aritfacts step back in fives on the core

My problem is that it won't let me. Every time I click Apply the voltage goes back to stock. Do I need to turn on the force constant voltage feature? And I'm sure you are right profit on the voltage since my max temp has only been 54 deg. I'm just as broke as I am curious though so I am being very cautious with my adjustments biggrin.gif Thanks for the fast reply

Okay MSI afterburner will not let me up the volts any less than .975 solution is go higher lol. Thanks again I'll post my final results for the fun of it:applaud:

Okay this is where i am at. The voltage can go no higher and I'm not seeing any benefit in clocking any higher. To be honest I am disappointed in the results. I'm still only at 60 degrees Celsius so as far as I can tell I'm at a "safe" clock. I ran a stability test for 20 minutes and it stayed rock solid with no artifacts. Can some one tell me if my expectations were too high? Or am I not doing something else right? 985mhz on the core clock is higher than I've seen any one else take the gtx460 on the submission page but there numbers are better. At the same time mine runs cooler and seems like I can go much higher????????

If you're hitting 985mhz on the core, then that's about as high as you're going to get.  In fact, I don't think I've seen anyone go that high unless they are running a special bios to allow for 1.15-1.2v.

it really isn't just up to the core either. memory is also important there is a happy medium between the two. Peronally i like to up the mem up the its highest stable back off a bit and then push the core as high as it will go. after benching you can begin to knock down the voltage until all become unstable then boost it up a few. I never saw the need for a custom bios, but maybe i just never had alot of time and fear of a big dumb eye sour of a paper weight until the rma is done.

Forcing v2.0.0 to control core voltage via generic GPIO circuit just like v1.6.1, it can be done by editing the profile file (MSI Afterburner\Profiles\VEN_10DExxxxxxxxxxxxxxxxxxx.c fg) and adding the following section to it:

[Settings]
VDDC_Generic_Detection = 1
VDDC_uP6262_Detection = 0

However, in this case voltage adjustment range will be limited to NVIDIA generic 1.087V.

It's a known issue of MSI A/B with 460 Hawk's tripple voltages.
