SmOgER So IMHO at the present time swearing by that magical VTT number of 1.35 or uncore ("max 3.6Ghz"?) is ridiculous. If it degrades it degrades - but that's very unlikely to happen soon. Worst case scenario - you replace a CPU for affordable price and OC it again.

By lowering the clock speed of the ram you may also be able to tighten timings so you won't even notice a difference.

On X58 platform RAM and uncore speed is hands down better than tight timings and low speed - tested numerous times. If it took the whole 3 years for some degradation to occur I simply don't sweat about it. Plus it's not like these CPUs are expensive nowadays anyway.

99belle99 Still rocking my X58 build. Playing GTA V at 4k 60Hz is pretty good going for this 10 year old build. Gone through a fair few graphics cards over the years and SSD's. HyperX Predator PCIe SSD is my current C drive with a 960GB SATA III SSD for storage and games. The Hyper X is faster than SATA but not up there with current NVMe SSD's.

I've had a graphics card not really worth mentioning as I didn't game at first and then a GTX 580, R9 290, R9 Fury X, Rx Vega 56 and my current Rx 5700 XT which I am amazed with. It's a great card beats out the 56 easily.

99belle99 Yea I forgot to mention I only use 3 sticks.

Totally. If they aren't all matching that could contribute to unstable ram as well

99belle99 About that 1.35v for QPI/vtt I run 1.235v at 200bclk and 21 multi for 4.2Ghz, 1600Mhz RAM, 3200MHz Uncore and 1.3v Vcore. And it is stable for the past few years at that. Computer running everyday. A lot of days for many hours.

Zetren Thanks for the help, so far upping the QPI/Vtt has resulted in no more BSODs, so fingers crossed. If another BSOD occurs I'll up the QPI one more time, and failing that run memtest again with your recommendations, however I ran memtest before and it passed, that however was at 1333Mhz.
