How high can u go Ln2?

you have backup?

What backup with SS cooling?

No, I always upload my highest score at the time.

If I had LN2 result, I'd have uploaded it.

This CPU was/is great on air/water, but doesn't scale very good with LN2 temps.

Mine does 5.3 on Cascade 1.7V and 6.5 Wprime 1.81V Ln2:)

Mine does 6.55-6.6 for Pi 1M, so it's not that good, but it's an old chip that I used 24/7 before and I have no other cpu for this category. It has a great IMC though.

All CPUs I have are bought retail from the store. If I want to bin a certain model, I have to do it the hard way - buy a cpu or 2 (depending on the price), test, sell rejects, buy another cpu next month and so on...
