3070 Ti Under volt

[13oots2]

Perhaps I am being a little dense here, but I understand one of the two methods of under volting, I get decreasing the core by -200 then pulling up a desired frequency then flattening the curve. Some people say this is not the way to do it and wibble on about holding down shift or something similar, can someone enlighten me about the second method?

Also, others say the memory should be good for a minimum of +1000, yet my memory is limited to about +200, yes it passes 3DMark at +1000 yet crashes out of Cyberpunk and Quake II RTX unless I considerably lower the memory clock. Either the posts I have read on other sites are misleading, or I have some duff Micron memory on my card.

Select your voltage point on the curve and drag up to the clock you want. Hold shift and left click above the point and drag all the way to the right so all points after are selected. Hold shift again and click enter, you may need to do this twice. You want a flat line after your point. If shift enter hasn't worked the line won't be flat. Reset the whole curve on the main window. If this part works, check the voltage points before your increase have moved to keep a smooth increase. It can bug and not move them - you'll just see the background red line. Again reset until both the above is complete. If you want a higher clock or lower voltage, just reset and repeat.

Memory runs fairly warm or stupidly hot depending on your card. Check your temperature first with monitoring software. Smaller gains. Your inputs are doubled. One person may mean +1000 total, another +1000 for a total of 2000mhz. Error correction can lead to performance loss. The gains in games plus the heat and testing are never worth it when you can set a small clock increase knowing it's almost a certainty to always work providing temperatures are good. +100 to +300 for +200 to +600 total.

Thanks for the clear explanation, even I was able to get it

Memory temps are fine, my hotspot is another matter, at stock the card is running 83C on the core and 106C on the hotspot. Am loathed to take it apart after my last card died, hence me wanting to under volt this card. Hotspot is now sub 100C and core is 75C.

Plenty of video guides on you tube pal. It's really easy to do. Also you save loads on electricity (especially if it's not a FE card) with not much performance hit. I also have my memory overclocked +1000mhz although I'm not sure if this makes any difference

No I've found that too often it will only do +100 so I often dont bother with memory as in games it doesnt make that much difference.

I found the problem was my RAM overclock, I had reset the BIOS and missed bumping up a voltage, the 3070 Ti is now running +1000 on the memory with no issues or crashing.
