Hey guys,
I have a weird one for you, just wondering if anyone had any ideas. I decided to upgrade to a Ryzen 3700X from my old i5 4670k just recently, and went for an entirely new build, keeping my still-functioning older PC together and building on an entirely new platform. Thus, I built it in a new case and decided to use a new PSU.
Weird thing is I now have to lower the offset for overclocking on my GTX 1070Ti, and I can't figure out why. Previously I had it at +150 in Afterburner. I'm getting instability even at +120 now. My knee-jerk reactions would be either thermals or power delivery.
On the thermal side, I'm getting crashes quickly, before the GPU can even warm up. For example, using Firestrike as a test bed, it'll crash after 5-15 seconds, but the GPU only warms up to 55 degrees. Doesn't make a whole lot of sense. My old case had a side intake fan which my new case lacks, but I would only think that might matter if the GPU was actually getting hot.
For comparison on power delivery, my old PSU was an Antec HCG 750W, and I built this new PC with a Corsair RM650X 650W PSU, with plenty of spare wattage according to my calculations for peak system draw. I don't seem to have any PSU stats shown on HWinfo for whatever reason (not sure why), but the 12V, 5V, and 3.3V numbers in the motherboard section are all showing normal values. No distinct undervoltage present.
I tried boosting the voltage offset to 100% on Afterburner. This didn't help stability at all, but I did see that the GPU is now drawing the max voltage of 1.094V under load, as one would expect to see.
VRAM overclock offset remains stable at +375. I tried playing with that one as well, wondering if the lower GPU frequency might free up additional room there. No dice, it's at its limit.
Anyone have any ideas what might be going on? Is there something I'm not seeing?
Thanks!!!
