So, new PC:
R5 7600 with stock cooler & included paste (kinda wish now I had gotten a better cooler, but I'll just deal with it until I upgrade my CPU down the line)
ASRock B650M-HDV/M.2 mobo
G.Skill Ripjaws S5 Series (2x16GB) DDR5-6000 CL36
MSI Ventus GeForce RTX 4070 Ti Super
Windows 10
At first it was restarting randomly in Windows 10, even under the base 4800 MHz ram timings, and before I even had the GPU. But it SEEMS LIKE that was due to CPU overheat before I enabled PBO w/ 85C. After PBO was set, I never had another crash at default 4800 RAM timings. (I also have heard I may need to physically switch the stock R5 7600 cooler to be at a faster fan speed, which is fine I guess if it helps.) But it's also conceivable there's something else wrong with the motherboard etc, and I haven't figured out what yet.
- I then played with increasing DDR5 frequency. Even at the default 1.1V, with default timings, it seemed stable at 5800 MHz? Although I didn't test it thoroughly. However 6000 MHz was a no-go: got into Windows but peripherals didn't work, etc.
- Then after updating BIOS to the latest non-beta (v1.30) I tried the default XMP profile with 6000 MHz and faster timings (36 on most?), 1.35V and I disabled MCR. Unfortunately, it crashed Windows again.
- Keeping all of those settings but lowering to 5800 MHz, it seemed stable in Windows, and then for as much memtest86 as I felt like running last night (one full pass, about 35 min.) No errors.
- HOWEVER, today on coldstart I got 3 beeps which I think was another failure?? So, I went back into BIOS once again, lowered to 5600 MHz, no change on timings, but decided to try lowering voltage to 1.25V.
Currently in memtest86 and it's completed 1 pass with no errors, at 5600 / CL36 / 1.25V.
But basically, my question & goal is this: What should I set or change to get the EASIEST good performance from this DDR5 without worrying about possible problems every time I start up? I know DDR5 is a pain and I'm not worried that "I can't get my rated 6000" because I'd rather just get close to that and have a rock stable system. But I would like to get 5800 if it's possible. Should I try with different timings, and which ones should I loosen a bit? What voltage is generally good for someone like me who is willing to back off a bit to 5800 or even 5600 if needed? Thanks.
