I am hoping within a month or so. Ruffus has one of the stages complete. Just more more to go.

Call me a newb I suppose, but what is this cascade your refering to?

What is a Cascade?

This is where my current knowledge is pretty damn sparse and can only give a little information though I’m gonna guess if your reading this your not gonna jump into using cascades anyway

Cascades basically consists of cooling the condenser of one system with another system.
There are 3 kinds of cascades
Autocascade
Cascade
Triple stage Cascade

Autocascade – Can Get you down to about -80
Double Stage Cascade – Can get you down to about -100
Triple Stage Cascade – Can get you to -120 often even colder still.

As I say I know little about cascades but will update when I get some more reading done. But can say now they ain’t cheap.

Ah I was hoping there was another person making the cascade waterfall reservoirs. :-( Oh well

Good morning,

I think the link points to the wrong screen shot - (4.7), should point to 4.8 - this one - http://www.xtremesystems.org/forums/...&postcount=333

Good morning!

Yes, I see now, I forgot to change the link of your entry. It is fixed now.
Thanks for letting me know!

Something is weird here.. LinX doesn't seem to like my X5680. I always get an error after exatly 3 minutes of runtime, no matter the clocks & volts - even at stock lol.
I am primestable at 4,5Ghz with ~1,375V Vcore, BOINC Gaming etc is stable as well.
So it stands to reason that LinX has some kind of quarry with my chip? It has been very buggy on all hexas to begin with

Try without "All" memory setting, mine does that sometimes.

I can usually tell when it will happen since I get a "Windows Media Player has stopped working" error about 30 seconds before

[newhit]

Had another rethink about my settings and have managed to get another submission, although my temps and Vcore are now contributing to climate change.

Hope it's OK

[SteveRo]

newhit - yeh, that's getting up there - good run! probably need to upgrade your cooling before you go any further.
I did this with an i7 965 - don't worry - the proc's temp self protection kicks in around 100 - maybe its 101.
Of course yu know to only do this for benching - don't run it 24/7 at these t's it will limit the life.

Cheers Steve. I was thinking about a chiller but then cost v perf started to bite. I have reasionable Vcore and HT on at 4.5 for everyday use.

Chiller's are better than water but most - mine included are only marginally better not a huge difference then standard water cooling.
For most xtreme types water cooling is as far as they will go.
Phase change cooling both single stage (SS) and cascade (multi stage phase change) is the next level up.
Lowfat is waiting on cascade to be finished - he is currently on a SS.
I'm a step behind him, I'm getting a SS made for me by sdumper.
Others who have this unit say the SS will hold an overvolted i7 at -40C (300W load).
I expect to take my 980x to 5+ghz and hopefully get competitive at pcmark vantage again.

It's not just OK, it's pretty amazing, congrats!

Is this yours? If so, can't wait for the results, looks like a monster unit!

[SteveRo]

Zalbard - no not mine but sdumper said what he is making me will look like this.

Edit - By the way - why isn't there any 930 oc's showing up here yet?

Don't know the batch number.

How much does a good phase change/cascade phase change cooler unit cost?

You should contact sdumper - he is a phase change custom buider, several folks have bot from him and have been pleased. see - http://www.xtremesystems.org/forums/...d.php?t=237415

Water cooled.

Batch 3003b396, it seems to need more voltage than other batches for 4.5, 4.5 24/7 might not be in my cards.

BUT, I wanted to go to sleep last night so I made the mistake of increasing 3 voltages at once, now I will have to start over to figure out what finally made linx stable.

At least I'm finally in the club!

[tool_462]

Welcome to the club

1.424 idle isn't unreasonable for 4.5Ghz, what is it under load? 1.408 or 1.392?

[mbreslin]

1.440 under load :/

Can you look at the rest of my v's and see if anything jumps out as being too high?

[tool_462]

Even then, check the OP Yours isn't any worse than the ones listed (I'm aware there are some batches un-represented that are taking less to do 4.5 24/7)

You shouldn't need anything above stock IOH Core for those settings, not doing any harm at 1.28v but probably be perfectly stable at 1.1v.
