We should rename this entire thread; "DJ's Nvidia modding thread, where you can get yours done right!"

+1 DJ

Personally, I think you should have 100 +1's by now. These guys are so stingy man. Almost every post you are helping someone.

were you reading the clock speed in heaven or GPU-Z, heaven reports the max clock speed for that power level not the current clock

a 650 Ti boost is more of a 660 than a 650 ti, so i don't think that would be a good idea

this right?

Probably yes, if you have reached to a point where you have 1,212V unlocked and it's running flat at fastest speed it can manage with reduced and overclocked memory speeds then probably no power problems. I would downclock memory and try if gpu will oc higher or not...

EDIT: that in picture should be the max power yes... but i was pretty sure that it did not work for me at start, because it is already pretty high by default and i'm not sure that even setting it down to 250 will do any damage to my straight gpu speed line in afterburner while gaming.... but i have mine both at 260/280...

Is your card running at 1346 stable? 1,212V iguess? And seeing your memory clock i should ask that are you not hitting into gddr5 error correction too hard and therefore start losing fps or is it tested that you gain some? Warning: Spoiler! (Click to show)
Since you have 2G version then like i said it might not cause any problem on those because it has less memory to feed through pci-e power and every saved W = 6W more to gpu in mu case, atm it is sucking 44W through pci-e, 6W from 6-pin, 9W from 8-pin, so little calculation means that 44-3=41W is consumed by card itself, memory and fans... during gaming etc memory etc eats more too, fan spins higher, even when they do eat same, 66-41=25W and 25x6=150W that my gpu was able to consume + some % more that is allowed x6 so it seams about right, don't know how much gddr5 comsumes, but if 2G is like 10W less, then you have already 35x6=210W + some % more by default to dedicate for GPU only and might never run into this problem...
By reducing memory from 3400 to 2900 i already get 2W less from pci-e etc...

If it starts to throttle down, then power/temp problems, and if it starts to crash at heaven or some more demanding games then it might be power/temp-related voltage problems... that meaning it is running near limit and slight voltage drop due to power demand could trigger it getting suddenly getting under 1,2V while needing 1,212 for a moment and crashing... or it is trying to lower speed or voltage and resulting in crash, had slight problems with that and after edited bios voltage/speed table slightly...
I was testing with -500memory if it is stable @1333, got 1 minute heaven crash, running at -750 memory resulted it being 10 minute stable... Since before i got heaven crashing after 10minute run in 1,2V@1306 then it probably was little voltage drop that caused crash... Now i have more power so maybe i can do a very little edit on top speed pin/voltage part... While testing for top speeds on voltages i did not know yet about the real problem, only started to notice that memory clocks affected gpu clock...

Need to desolder my multimeters sometime biggrin.gif

I monitored in Afterburner, but i guess heaven was showing same speed, because i'm running last available speed pin in bios. If i start heaven now it will show only 1306.

thats not a good idea as the 650ti bios is a very wierd one you should do that manually as it will be safer than using a different card as the 650ti can easily do 1215MHz if oc'ed right. with a power boost that card can be a beast. In mining it almost caught my gtx 660's. till i oc'ed them.

you can but what i am having you adjust is your power table on the power table all the max figures should be at 140% except the third one that should say 120% all this on the left side of the actual number variant. when you see the percentages listed as i am having you set them you should notice a difference but you will need to set your cudaminer config to auto and add the new figure to your script. also a note to oc cudaminer for some reason performs better if you downclock the mem clock and oc the core clock higher. its a nvidia thing. amd cards work better with more mem clock.

So only change the max and not the def fields?

Yes, it is stable at that speed. Well, last time I checked it was still an improved FPS indicated by Heaven at that high memory clock so no I'm not yet hitting GDDR5 memory correction. Although, I have to double check on that.

Setting at 250W will not damage the card at all. It's basically setting the max limit and the draw is ultimately dependent on the card load anyway. Increasing the GPU clocks more will produce a crash in Heaven and increasing the mem clocks usually produce artifacts OR a Heaven crash as well. Does that mean voltage problem? Or can using KBT 1.27 to adjust the power throttles alleviate these?

look at this gigabyte gtx 660 users:

Gigabyte is using an OnSemi NCP5395 voltage controller on their card. It does not provide software voltage control via I2C or any monitoring features.

looks like hard modding is the only option.

http://www.overclockers.com/galaxy-gtx-650ti-boost-review/
this part is worth mentioning
"Galaxy has made the choice to beef up the GTX 650 Ti Boost PCB and give it a bit more in the power delivery area. This can be seen with a 4+1 power phase configuration as opposed to the 3+1 on reference boards."
are these last 2 values even possible to use? i thought 150k was the limit for those, though i have seen 160k on that value on my RMAed card's stock bios (RMAed over a bad fan)
