Yeah I flashed with 3A, 1267 is as far as it's going I think.

1267mhz with stock voltage, but with +50mv on the core you're not stable at even 1280mhz?

Are you using Afterburner 2.2.3?

Edit: Sorry, just saw you're using 2.3.0. Did you do the config edit?

No no, I can only go +30 MHz with stock voltage normal BIOS. Sits at 1215 MHz at the highest. Going to +40 MHz (boost = 1228) will crash very fast.

With the LN2 BIOS 3A and no added voltage (+0 mv) it does 1267 MHz max in games. Adding 50-100 mv does not change this limit, that's all it's capable of. Interestingly it will do 1254 with -37mv. Not a chance of going over 1267 regardless of voltage though, it crashes in seconds. It has many drops to lower frequency when gaming like this though even with power slider at an appropriate level and power % sitting around 60-80%. It causes slowdowns in the FPS making it unplayable.

I haven't done anything to afterburner at all. I'm using v2.3.0 - what is the config edit? What's it do?

use LN2 bios and download the 2.2.3 msi afterburner it will make a difference.

Some questions from a newb OCer of GPUs.

1) Do I have to open up Afterburner every startup for the OC to set in?
2) What increments do I increase Core Clock / Mem Clock by, and do I add them / test them separately, if so which do I begin with?
3) After finding the max stable clocks, what increments of vcore do I increase by?

Thanks, I don't have the card yet, just doing some prereading tongue.gif

*** tried this now its running 1241 stock volts and 1320 at +93mv. What is going on?


EDIT - the voltage is quite high, 1.21v with DMM at stock (0mv) in LN2 mode, +50mv = 1.26v and +93mv is 1.35v. I didnt check v2.3.0 with DMM perhaps it doesnt apply higher than ~1.21v ?

HOwever in LN2 mode the core/mem speed is still always dropping making benchmarks and games jerky and score poorly. Is anyone else experiencing this? Normal mode works fine and holds at boost speed right through.

Whats better, a card that does high core or high mem? My card will do +900 mem (7600 effective) game stable at +20mv and scores do benefit in benches going this high. Just testing now but wondering if someone has already done this to see which gives larger gains? ie: card at 1350 core / 7000 mem or card at 1250 core and 7600 mem

You surelly skiped the part to edit file to unlock lightning voltage control on AB versions after v2.2.3

VDDC_CHL8318_Type = 1


Those lines disable NVIDIA's capped voltage control module, enable voltage control via direct access to CHL8318 and select offset voltage control mode for it.

Note: each card profile must be edited for SLI configs.

1320mhz! Problem solved biggrin.gif

Afterburner 2.2.3 was the last Afterburner version that allowed for native voltage control. With subsequent versions, the lines of code posted by elbubi must be copied and pasted into the config file before it'll be able to affect the voltage. So most just get 2.2.3.

I knew your situation sounded wierd tongue.gif Glad you don't actually have such a bad card afterall.

Stock on the unlocked 3A should be ~1.26v, and ~1.36v with +93mv . Yes, 2.3.0 doesn't adjust the voltage the same way 2.2.3 does until you do that config edit.

Never hurts to do some research ahead of time.

1) You can check 'Apply OC at system start-up' on the main interface, below the profiles. And save a profile.
2) That's up to you, as far as the increment. I'd start by +50mhz the first time, and if that's stable then go up by 10 or 15. And it's a good idea to do the core and memory separate and together. Some games you need a higher core, sometimes memory. And one max OC will affect the other (lower max stable core clock with a high memory OC). So, find max core at a specific voltage, then put it back to stock and test memory, then test both at the same time raising one at a time, finding the highest combo OC. That way you have a max OC for every situation (when you need a high core, when you need a high mem, when you want a combo of both). Do this for a few voltages (stock, +50mv, and +93mv) and now you've got multiple methods of attack at multiple voltages depending on the particular game thumb.gif
3) This is up to you. If you're crashing at a clock(s), you can raise the voltage to get a little higher. I just said find your max overclocks at +0mv, +50mv, and +93mv as an example, so that you have an overclock for different situations, but you could very well take the time to find overclocks for even smaller increments (oh and don't forget about the memory voltage too)

Played some with v2.2.3 - still not a great clocker, needs >1.30v for 1320+ core

That said, mem seems strong on this one. Did some testing with kombustor which seems to load mem harder than games, see below stable for over 20mins when I stopped it.

+855 mem (7720 MHz effective) at stock mem voltage. Core needs +18mv (1.25v real @ DMM) for 1254 stable

What's better higher clocking core or higher clocking mem? I though these cards were more mem bandwidth limited and core was less important in terms of actual performance.
