Talking 965 + LN2 = 6.7GHz

Well it had been a month since I benched anything, but I was right back at it today!

Killed a motherboard in the process unfortuanetly, RIP to my 990FXA-UD3, it was replaced with a M4A88TD-EVO/USB3 for most of this session (only validation was on UD3) which did a fine job despite a 1.8vcore limit. I was also only able to bench with one stick of ram with this CPU, have no idea what the deal was there but I tested three kits of ram and two different boards and it would only go with one stick.

Very nice. I just wish there was some way to put together some kind of closed system that didn't always need new LN2. Guess I'll always be wishing.

The closest you can get to that is a Phase or Cascade system. A really good cascade unit can have you down to -90c idle with the flick of a switch.

True .... but does that ln2 last forever ? Or do you have to refill it ?
Those thousands of $ for the cascade is spent once

@ the OP : that' just amazing work there !

There are pros and cons to both. LN2 is a smaller bite out of your wallet when you need to refill, and much colder temps. Phase or cascade is a huge bite all at once, temps not as cold, noiser, and requires more work space and special power requirements that most households do not have, so there's added cost there too.
Not dissing on it, I'd love a small SS unit. Just mentioning it is all.

At what point do you actually need to make a huge jump in colder temps? Its seems that those little refrigeration units (i forget what they're called) don't really get it cold enough to be worth it. Making water cooling better in the end.

Depends on what you're trying to accomplish. For average users and slightly above average users, water is usually good enough. If you're a bencher, it's not.

This.

It's not really effective to run subzero cooling for a daily system. Cost, power and space requirements all sharpely rise for what would be a small performance increase in comparison. That and condensation is definitely something I would want to be dealing with on my main PC.

I use LN2 because it is the coldest form of cooling available to me and I only use it for a matter of hours at a time. Im a bencher and cost vs actual performance increase in the real world is irrelevant to me.

Now that's what I'm talking about! Very impressive results there JR. That's strange about the cpu/ram issue.. doesn't look like the single channel hurt the scores much if at all.

Just curious if you tried for a max cpu-z with all four cores active?

Last time I tried deactivating cores was with single stage and didn't seem to make much difference.. might give it another shot on the cascade.

Thanks for posting!

I figured out why I was having memory problems after I finished my session, had somehow managed to get a little piece of kneading eraser (I use it to insulate) on a CPU pin which looks to be the culprit. Definitely taping the socket area off from now on.

I have no actual validation and didn't really try for one will all cores going but when I was going for my wprime 32m run I managed to boot in at 6.5GHz, which crashed as soon as I ran the bench. So I'd say around 6.5 would have been the limit anyway, not half bad considering the max validation was only ~250mhz above that.

Is that a 5450? I have an almost identical one on my ln2 bencher
