cascade

[ruffus]

hey guys once i work out how to put up the pics i will do so as i just wanted to show u guys how it turned out before i shipped it out. so if some one could tell me step by step on how to post pics now that i can not just up load them to this site:shrug:

[thebluemeanie1]

Navigate to http://tinypic.com/, click the choose button, select the image,(seems you can only do one at a time) click the big upload now button, copy and paste the line under "IMG Code for Forums & Message Boards" into your post.

Using http://photobucket.com/ may be easier because you can upload more than one at a time but requires you to register. After registering it is pretty much the same procedure as tinypic.com.:up:

^^ those are currently the only way you can post images here. Image uploads to XtremeSystems was disabled a while back after the database kicked the bucket like it did. Hope it comes back sometime soon :(

so i think i got this right so here are some pics and i have it holding -90c at 300w (on load tester)
now when i have it on a cpu and do some burn ins (100% load) it never goes below -103c
but will be doing more cpu testing tonight and i will post some screen shots of how far i have the cpu overclocked

[ruffus]

and if this guy that it was built for does not get a hold of me soon this unit will go up for sale

[sdumper]

I really get angry when people ask you to build them a unit you fork over your own time and cash to build it for them and then they go missing in action.

Sorry for the rant but it happened to me recently :)

Anyway thats a cool case how did you bend the angles like that?
Also I cant tell but did you use a TXV or dual cap?

[[XC] gomeler]

Nice work, more internal shots? Second, where did you get the case?

[teyber]

nice work ruffus! that came out incredible!

[runmc]

Very nice Brad!! :D Is that condenser the one you got from the A/C window unit? What are the dimensions on that condenser?

[ruffus]

@ runmc yes it is one that i got out of a a/c and its 24" long and 18" tall 3 row

about the case guys me and a friend made the case out of 18 gage steel and use a brake to make the bends then got it powder coated

@gom i will get some more pics of the inside as well as pics of the process of me building
@sdumper it is txv

[clear cmos]

nice cascade very compact :cool:, nice load temp. too

are u using cpev on low stage?

How did you create the grill holes? It would have taken me forever to drill all of those holes. I absolutely hate making cases because they always take me way too long, cost me a fortune in materials, result in me cutting my hands, and in the end my cases look like sub-par.

[Foamy]

hmm i love cascade :D

Good job!:up:

[[XC] Oj101]

Looking good, the long suction hose must make it a pleasure to use :up:

looks good buddy. if you want to do some testing on a killer CPU, just let me know...i might have one lying around here that loves to run 5.5GHz at -100C :D

you also have a PM incoming :up:

nice work there ruffs.
300w is alot of heat :yepp:
wprime on i7 will be around that, other wise most other benches are alot less :up:
What cpu are you benching, look forward to the results.

[ruffus]

well guys i have just been benching some old p4 775 socket cpu's but i would love to get a quad on it to do some real testing as the 300w is load tester watts and its just not the same. so as asked here are some more pics. and thanks guys for all the nice words

[sdumper]

I see your using a Sc18clx2 for the second but what did you use on the first stage it looks massive?
Also are you using a suction line accumulator for your receiver?

[teyber]

looks like its a expansion tank that doesn't have a cap tube connected to it. Shouldn't really make a difference :) Only difference is it dumps the entire charge of ethylene when it starts as apposed to just letting it out

[sdumper]

:)

That appears to be a suction line accumulator (which is often used as expansion tanks) if im not mistaken but for the first stage with a TXV I thought it was best to use a receiver to insure only liquid fed the TXV :shrug:

[[XC] Oj101]

An underclocked and undervolted i7 MIGHT get down to 300w for real like testing :rofl:

I'm jealous of your unit, what's the power consumption like?

[thebanik]

wow!!! nice work brad, put me in line if the original owner does not turn up.......Let me contact you on gmail.........

[eligray]

Hey Brad!

That unit looks amazing, great job. You seem to be a master of getting/making high-quality parts inexpensively!

What size AC unit did that condenser come out of? 10k BTU?

And I'd like to recommend that you try the cascade out on a wolfdale (or similar low heat output CPU), so that this unit doesn't have the same floodback issue as the SS I bought from you.

That said, I'd like to tell everyone here that Brad really stood behind his work, and was fully willing to pay to have my unit fixed by a nearby builder. Anybody can make a mistake such as that on a unit, but Brad really took responsibility for his mistake. He's an extremely helpful person, and judging by these pics, a nice cascade builder as well :D

Cheers,
Eli

I have no idea what your talking about but its nice to hear compliments about a builder standing behind his products.

Nice job Brad!!

[ruffus]

@sdumper
in my pics there is 2 recivers side by side one with the rotolock on the top is the reciver for the txv and the other one i cut the rotolock off of it and welded it up as it was one that u could not take off then i used 3 meters of 0.031 captube so it would work as my expation tank oh i guess u can't really see the 2 recivers but they are there
now for the gril in the front and side i just cut out the holes and tacked welded in the steel stuff with all the holes in it (so no i did no dilling of the holes i bought the steel like that and for the first stage compressor it is 1?2hp 8000btu compressor i got out of a real big pop cooler from a conveince store
@eligray now unlike your system where yes it had a little to much gas in it the first stage has a reciver on it and a big accum on it and for the second stage all the r1150 would boil off way before it would ever get back to the compressor.
@Oj101 i will get it running again tonight and i will post power consumption tonight.
ok guys if i missed answering any thing let me know

[lesstutrey]

It's sad to me that the builder closest to me (that i'm aware of) is in canada. Only 471 miles each way, first person i've seen within 500, a distance i'd probably be willing to drive for a nice 2 stage. On another note that is a beauty, and those are some great temps at that kind of load. Real world results will be even nicer. I'm currently in this state of cascade envy, RunMC fixed me up so i don't have SS envy anymore thankfully.

[ruffus]

well guys 30ho i think that is how u spell it is comming over tomorrow to do some runs with a I7 so i can and will post some stuff tomorrow.
now the only one down fall i have found with this cascade is that it needs its own 15a breaker and would be better to have its own 20a one and it uses 1200 watts of power

[sdumper]

yep see the receiver :--)

What does the suction line accumulator give you? I would have thought the TXV would have solved your load problems.

--edit-- I love the spit and polish on the joints by the way it looks so clean.

[ruffus]

@sdumper not to sure what u mean by this (What does the suction line accumulator give you?) and ya the txv worked out good but i had a real hard time getting it ti hit -40c and with the second stage on sometimes it can get as high as -20c so i think on the next one i will go with cap tube or i do have this other txv that is rated for -50 but it is not ajustable. what kinda loads and temps did u get with your cascade the one that u used cap tube on as well what did u use for cap tube size length and number of

[sdumper]

loads were close to -45c...with my last cascade but so far -47c unloaded with this one...im sure its just some tweaking.

What im confused about is the suction line accumulator you are using on your first stage discharge before your compressor. I have not used one before an am not sure what it gives you.

I have an extra one and can easily add it but am curious what the performance benefit is.

Ill send you a PM so I dont sound stupid ..hehe :)

[Unseen]

nice condeser :)

I hope you wont have problem in the future with this type of wood + water drops.

[[XC] gomeler]

Good point, should paint the wood black.

[ruffus]

ya i was thinking the same thing about the MDF board as well i was thinking about painting all the high side pipes
as well i spent the day doing so overclocking and some hard core bench runs on the system so that i have some good numbers to have posted when it goes up for sale as i still have not got any msg's from the guy i built it for so i am giving him 1 more week then i will be sending him a email saying he has 1 more week to contact me then its going up for sale. so 3ho6 will be posting all the numbers as well as a review for all u guys that have a intrest in this system. so 2 weeks and it will be up in the for sale section.

[3oh6]

yup, got home a few hours ago and all i can say is i am hooked, that was some smooth benching. the unit really impressed me, keeping in mind it was the first time i benched with a cascade. in total i think we ran about 6 hours straight through, mostly just 06/Vantage/WPrime. the goal wasn't so much maxing the CPU, but trying to test the system at such a high load, check pressures, and to simply see what it could handle.

i did get close to maxing out the W3540 in 06 though. i came up with a run at 5300MHz. compare that to the max i got out of it on LN2 of 5352MHz at the same 1.599v found here... http://hwbot.org/result.do?resultId=892341 . this was ran at -106C down to -95C on LN2 with an F1 Extreme. today the Cascade would idle at -98C and run all 3D tests in 06 at -98C. during the CPU test i think temps were only getting to about -88C ~-86C if memory serves me correct. i wasn't writing temperatures down - which i should have been - but i think that is how the temps worked. either ruffus or Ozzfest05 if you can remember the numbers chime in. either way, here is the screen shot...

http://3oh6photos.com/forum_post/xs/09_09/06_5299_36364-1.png

couldn't get the GPU's to clock worth a damn as it was too hot in there or the volt mods weren't kicking in on all cards.

the max i could do in Vantage was 5.2GHz. i had never ran this chip on LN2 for Vantage because the ATI cards suck so bad. again, low GPU clocks because they just weren't playing nice. i believe the temps were again -98C through the 3D tests and then warming up to -77C at the end of the first CPU test. it would then pull back to up to -82C in-between CPU tests and hold -83C through the second CPU test. as soon as the CPU tests end, the temp dropped back to -98C in a couple seconds. here is the screen...

http://3oh6photos.com/forum_post/xs/09_09/van_5208_31471-1.png

again, we probably could have got more out of the CPU but we were trying to push the unit more than the clocks so it was a balance of enough voltage and running stable to test pressures on the second stage.

i didn't run any single threaded benches like SPi or Pifast as we were focusing on max temps. we did run some wPrime both 32 and 1024 but after passing 5.3GHz in wPrime32 with no real effort we moved to 1024. it was finally wPrime that could bring the cascade to it's knees. i can't even remember what 1024 did run...i don't have any screens as we didn't spend much time on wPrime. but at 5.3GHz with 1.60v it would only last about 80 seconds of wPrime1024 before temps got down to the low 70's at the test would freeze.

i would love to have that thing at home tonight as now i can see what i can run on LN2 and i think i could match every single core run on LN2 with the cascade and this setup...1M, pifast, 32M, 05, AM3. i ran a few 05's and the temp just didn't move at 5.3GHz+ with 1.60v through the entire test. -98C the whole time. i ran a couple AM3's at 5.3GHz as well and it just didn't budge.

the really nice part of this unit is the bypass that let me warm up to -55C ~-60C within a minute so i could change memory ratios/CL/cpu ratio or if the system powered down. this let me completely bypass cold boot bug issues. after getting post, just turn the bypass off and by the time you are in Windows the system is at -98C ready to rock. cold boot bug really wasn't a problem with this chip. not sure how other CPU's will handle it though as the cold boot bug issues are all over the place. all i know is there was absolutely no time lost to cold boot bug with this setup today.

overall, it was a fantastic afternoon benching for the first time on cascade for me. now i must resist every temptation to get one built for me :D

i even got a tune up on the Chilly 1 single stage, it will be like a new machine for me. thanks again guys, we'll definitely have to have another session sometime soon...with 32M in mind :up:

[gosmeyer]

Strong!!

[ruffus]

ya thanks again 3oh6 for all the time u spent pushing this system (6 hours) so i would have some numbers to show u guys as well as some one that is a well known extream overclocker . and one thing he left out was when we got the real high temps like the -5Xc range the system had been running for at least 3.5 to 4 hours and the room we were in had to be atleast 80f to 85f so this would have had some affected temps as well as pressures

[Ozzfest05]

The numbers from evap temp probe in 3dmark06 went -94 was the warmest temp we seen after first cpu test, second cpu test in 06, well the unit recovered to -96 - 98 ish as it doesnt seem to push like the first,
The room we were benching in after about 2-3 hours got mega hot,
I would say we were benching in +21C temps at first then +29 :> and of course the idle of the unit dropped accordingly I cant imagine a canadian winter bench session with this thing or even an ac cooled room,
BTW Jody is sick with the classified
Do you think he noticed I stole his 32m tweaked OS :>

[sdumper]

Room heat makes all the difference. When I bench for long runs I do it outside in my garage because of noise and because of heat built up.

I bet if you ran those sessions out in your garage in the afternoon or night your temps never would have dipped below -90c. Also you might want to play with your TXV valve a bit on the first stage if the first stage load temps are warmer than -30c.

Again very nice job and I really dig that case!!!!

[ruffus]

thanks again guys for all the kind words and for tweaking the txv i will try but i know that i have been tweaking it for 2 months and i can't seem to get it any better i really am starting to think i need a bigger CFM fan on the first stage compressor as well as a higher cfm fan for the case as the air that gets blowin out of the case is smokin hot

[wdrzal]

Just check your subcooling before changing your fan, you only need to maintain a few degrees. I would think you should have around 10 to 15 degrees superheat @ exit of interstage HX. If your superheat is ~20/25 degrees or more you need to adjust you txv or put a larger orfice in it.

By the way NICE JOB and NICE CLOCKS :up:

[ruffus]

ok guys i think i have waited long enought for this guy to contact me so i am going to email him one last time and if i don't here from him by the end of the weekend it is going up for sale but u guys will have to go look in the for sale section as i can not put anything here

[sdumper]

bummer sorry this happened to you..seems like dejavu

[Buckeye]

Interesting hearing you guys talk about the heat output you are seeing.

I have run mine for very long periods in my room and I never notice the room getting warm, it is a rather large room tho.

The noise does get to me after a few hours but its all good.

Mine does not have a hot gas bypass but I have yet to run into a cold bug issue with it, besides a Core I5 750 that CB'd when it got near a ice cube :ROTF:

[sdumper]

Your wife lets you run a 2 stage cascade inside your house?

[Buckeye]

I do everything in my benching room which is actually a converted living room, fire place and all that jazz :)

Yeah none have complained about the LN2 Dewers, Cascade operations or anything... yet :)

They just think I am crazy and don't get to close when I am benching LOL :ROTF:

[Gunslinger]

I run my 2 stager in my office all the time, which is about 12' x 14' and it gets very warm. Boy does my wife hate the noise also. :D

[sdumper]

My wife would kick my tail :)


No wait...she does that anyway :)

[ruffus]

ya my wife does not have much to say i would just tell her if she does not like it then she does not have to come in to the back room

[lesstutrey]

hah, just my one stager makes enough noise for me, fortunately i am located in the basement all isolated and cold with a dehumidifier rated for twice the room's size. Never noticed it warm up the dinning room when it was in there.. but i usually had one window open and then another window creating a nice airflow.

[thebanik]

wow brad, sick results with the cascade, if only I had the funds for this and you would have allowed it then would have grabbed it with open hands.......

[sdumper]

Is this up for sale now?

[Ozzfest05]

Sdumper it is pretty much up for sale he is just adding another exhaust fan inside the case ,
He needs to take some new pictures,
Once the pictures are taken it will be up for sale,

[ruffus]

yes it is

[sdumper]

Very nice price and a bit of a steal but im sure you want to move it quick.

[ruffus]

ya well i try and keep cost down as much as i can as i know every one does not have that much cash to throw around

[eligray]

a bit of a steal but im sure you want to move it quick.
If it weren't taboo to do so, I'd love to say how great of a deal Rufus gave me on my SS w/ acrylic case. It was amazing... :D

Hope to see your unit sell quickly, Brad :)
