fricknbot Posted February 14, 2023 Share Posted February 14, 2023 So XMP doesn't seem to exist on my laptop / ram sticks have no XMP profile. I have manually clocked my sticks from 2666 to 2933mhz how ever the one setting in the bios that never seems to stick is the voltage which always resets it self to 1.2v from 1.35. Any way to fix this? Clevo P751TM-G / i7-9700KF OC 4.9GHz Undervolted -95mV / RTX 2070 / 32GB DDR4 @ 3200Mhz Link to comment Share on other sites More sharing options...

Any way to fix this? It should stick. What BIOS are you on? Also, does it get stuck in a boot loop after setting 1.35 or just doesn't apply?

I'm on the latest stock Clevo BIOS 1.07.29 it doesnt boot loop at all it restarts like normal it just doesn't change to 1.35v. If i were able too i would probably be able to push this ram further.

If i were able too i would probably be able to push this ram further. My best guess at that point is that it is a BIOS bug. In regards to RAM overclock the BIOS is buggy as hell. Tertiary timings is basically incomplete as they exist but don't do anything. Can't change to Command Rate to 1 it doesn't stick same like your voltage. And I believe it is bugged after 3333MHz aswell. I think it happens because by default you don't have an XMP profile on the sticks. Can you perhaps flash an XMP profile on the SPD and check if you can apply voltage then? For me I have had sticks that don't boot with 1.35V but that's exactly what happens, they get stuck in bootloop. That being said I do have a P775TM1-G but I think the BIOS should be exactly same between 751 and 755. Only other thing that comes to my mind is maybe if you had unlocked BIOS you could set the voltage in the other OC section of the BIOS. There are 2 of them. One is stock and one can be only seen on unlocked BIOS. There are more options regarding RAM and Voltage above 1.35 and below 1.2. Maybe setting it through there would make it stick.

Yeah i wanted to flash the Dsanke bios but I dont wanna brick my board and I honestly just got lucky when i updated the bios the last time. I wish BIOS flashing was easier but i dont know how the hell to get the dos commands to work and i dont wanna use a flasher Clevo P751TM-G / i7-9700KF OC 4.9GHz Undervolted -95mV / RTX 2070 / 32GB DDR4 @ 3200Mhz Link to comment Share on other sites More sharing options...
