New Prometeia owner, open for suggestions...

[dabhpr]

:welcome: Hi, all. Got a Prometeia on the way, along with the Socket T (775) kit to use with my Q6600, one hot little bugger.

Stuck at 3.0 GHz right now, with an Ultra 120 Extreme on it at this time.. and it idles at 48C at 1.45 vcore. (EVGA 680i A1 motherboard, swapped out for free from EVGA) It hits about 68C at full load after about an hour. YIKES.

Hoping I'll get to 3.6 GHz with the Prometeia.

Any suggestions, "gotcha's" or tips are VERY welcome. Please feel free to chime in and state your experiences.

I'm a complete phase-change NOOB. I am not a computer noob by any means, but phase-change is an entirely new road for me. Thanks in advance for all your words.

[p8ntslinger676]

the mach will have a hard time holding low temps with a quad core clocked at high speeds, thats about all i can tell you, hope it helps :)

Ballistix is Crucial buddy. And are the temps negative? :confused:

[AliG]

Just a word of advice, see if you can get it returned before it's too late


Here's why, the compressor and condensor on stock phase changes are only enough to disappate 250w of heat. So when you oc your quad or even when it loads, the phase gets overloaded and you get wack temps and run the risk of burning both the phase and the cpu out.

So there's two options, the first would be to return it for a custom phase (will include links or you can pm some of the people here) as I mentioned at first, or you can try to mod it yourself if you feel custom doing that, but I don't recommend it

Here's what I recommend for a quad
bare minimum, this is a very nice one made by juni here, but send him a pm to make sure that he will include a compressor that's strong enough for the quad
http://www.under-the-ice.com/index.php?cPath=41&osCsid=36cb4623575cacc0e2adbf7f908d6d2d
It's actually my favorite one because of the case, but you can diy on the case part by simply transfering the internals into a lian li v2000b case with a more powerful phase

here's one made by chilly1
http://www.under-the-ice.com/index.php?cPath=42

That shop is owned by runmc here at xs, but you can find the same products for a bit less if you pm the people directly, he tries to make a bit of a profit off the products which is to be expected

[dabhpr]

Ballistix is Crucial buddy. And are the temps negative? :confused:

Crucial it is,(DUH) correction made. Thanks. The temps aren't negative yet, since I don't yet HAVE the Prometeia.

Hopefully the Q6600 won't exceed the capacity of the unit... the message following yours is rather disheartening... we'll see. It is second-hand, not new, but it will pull -60C at no load. And I'm paying a LOT less than $920! And on that post's thoughtline, I don't plan on exceeding 1.55 vcore, so I am NOT looking to pump the hell out of the voltage on the processor... Again, we'll see what it can do, right?

Keep the comments coming. All is appreciated!

[[XC] 2long4u]

A refrigerator repair shop should be able to swap out the compressor and condenser. You can buy them from under-the-ice.com or the refrigerator shop may be able to get the compressor but I doubt they will be able to get the condenser.

[wdrzal]

:welcome: I no expert on oc'ing but refrigeration is a different story, you should be in the -20C to -40C loaded range not familier with that unit never seen one in person ,but your temps indicate a problem, How & where are you measuring them to start with.???????

Ok, guys - I **don't** have the Prometeia Mach II yet - it's being shipped and should arrive by the end of this week. My temps as listed in the first message are those gained with the Ultra 120 Extreme - NOT with a Prometeia...

I'm just looking for some feedback, suggestions, helpful hints, constructive criticism, etc. for my new endeavor. And I do appreciate any and all comments.

Thanks again!

[jimmyz]

ok here goes.
you will quickly run into a wall where the chip is going to generate too much heat for the prommy to handle.if i were you i would pm a custom builder, noob or runmc etc. they will be able to help you decide whether or not what you want to do is affordable.

you can lower your expectations some and be happy with what you have now and just keep an eye on voltages. and wait for the cooler chips that will be coming out with the 45nm process. the prommy will be able to handle those i'm sure, as they should be much cooler than kentsfield.

as to the unit pictured above in the link at under the ice. that is my baby there, jin built it last year for me. and i can say after having it for 6 months + that it will not hold a quad to acceptable temps. don't get me wrong it is a beast with a dual core, i have had my 6600 at over a 100% oc (4820) in my case with the doors on. it can bench all day with over 1.7v and the evap never drops below -38c. but it is no match for a quad with high voltage.
i see people linking to that unit (my unit is the one in the actual photo) all the time and wondering if it will handle a quad. i think ron or noob can build a unit that can handle a quad but it is going to be tough to tune and the unit will be at the limits.

most cpus hit a wall where you need to jump up the voltage a large amount to go higher. if you keep yours at a reasonable voltage 1.5 or under than i think you will get good results. if you want to crank up the v-core to 1.6+ then almost any unit will have a hard time doing it. why do you think i'm still running a dual-core..lol

like i said though before investing a bundle in getting it modded maybe you should think about the future chips since i bet they will have a much lower tdp.
good luck with whatever you decide and welcome to xtremesystems!!!

[wdrzal]

lets start here;constructive criticism,.............even you old unit should reach negative temps if working properly,that is a guess since I dont know the hp and gas but almost any unit charged correctly gets ino negative numbers.48c you can do better with ice cubes.maybe 1 ice cube.

Honesty is important here about you approx age past knowdledge and experience so we can judge what part of learing curve you are in,pictures of any work YOU have done also helps. Be honest, misleading white lies can be picked out a mile away, Did you know 60% of our members are engineers and 30% are either in school or planning to be a engineer. my estimate is 10% are truthful in their profile. that is IMO

Refrigeration can be deadly ,cause serious injury or burn your home down. Please be honest and don't over reach, their is a long learning curve. That was directed to all members who vist the the XS cooling section,not only the starter of this thread.

He is new and gets a mulligan:welcome: summer is here most are out of school so projects should pick up. I know thos I feel are honest with me ,I an more willing to help or point in the corrct direction.

Others can post their own comments.

[dabhpr]

Ok. I may have to re-tool my expectations for what I may be able to acheive with the Q6600. I do have an E6600 dual-core that would clock to 3700 MHz on a GeminII air cooler - it may prove to be the better candidate for the Prommy... I may very well give it a shot first. As far as I know, the Prommy can handle about 200 watts load.

Using the CPU calculator at Extreme Outer Vision (http://www.extreme.outervision.com/tools.jsp#cpuoc), it calculates the Q6600 at 1.55 volts and 3600 MHz to pull.... 300 watts!! Oh, HELL...

BUT, using the E6600, running at 4.2 GHz, at 1.55 vcore, it shows 175 watts. Still would be fairly warm (warmer than 0C, I'd think) but much more manageable.

OK> some questions: Should I use dielectric grease or vaseline (you tell me!) in the 775 socket? I don't think air space is a good idea, no?

I've ordered a supply of self-adhesive 1/4" and 1/2" neoprene foam. And some dielectric grease. What other supplies will I need?

Should I look for some conformal coating to coat the front and back ( or just front or back?) of the motherboard? Should I use the coating on the back of my 8800GTS to help protect it from condensation? (Which I REALLY hope I can avoid)

THANKS a bunch, "jimmyz" and "wdrzal". THOSE are exactly the kind of feedback I'm looking for. And no, I do not purport to be an engineer, nor do I plan on becoming one at this stage in my life. I was a Satcom Field Engineer (yes, a somewhat bogus title) for 21+ years until I contracted Peritoneal Mesothelioma; it's a terminal cancer. But I am still relatively healthy for now, and the chemo is still working. (Thank you, Lord!) Whatever time I have left is to be spent with family, friends and O/C'ing the heck out of my computer, heh.

Hey, if I have to use the E6600 in the main computer, so be it. It'd be really nice to reach over 4 GHz, methinks! I still have a secondary computer that I can transfer the Q6600 to. I'd just have to get a better motherboard for it (it has a Gigabyte 965P-DS3). I really like this EVGA 680i and EVGA's service has been stellar. I like their videocards, too.

[[XC] 2long4u]

Air is BAD! Seal everything. You should use the thickest insulation you can fit on the back side of the mobo. After you seal everything run the prommy for a few hours with the pc unpluged. You will be able to tell if it is insulated enough if there is no frost on anything. If there is you need more insulation. Seal every nook and cranny in the cpu socket. Dielectric grease is perfered but you can use vaseline. I don't know if it will get a quad sub zero but it may get sub ambient. Or it may burn out the compressor. Post some pics when you get it, and post screenshots of cpuz, super pi, and pcmark. You should get pretty good results on the E6600. You have a killer mobo, my buddy just got one. Im trying to get him to build one at the same time as me but he wants me to be the guinea pig. I am just waiting on my compressor.

[loc.o]

You should always use dielectric grease in the socket. The middle square and the area were the "dots" on the cpu are as wel. They tend to corrode rather fast. I always use a couple of layers nailpolish on the front and the back of the mainboard as wel were the backplate and bracket wil be.

Ive used me E6600 with stock mach II and for benching it cools fine. Full load as in orthos or prime dual is a different story though. Vcore a little higher then stock wil get mine above zero.

[Avman]

Always use non-conductive Grease in the socket - it might seem like over kill at the beginning but it will eventually save your chip and mobo. I like to use conformal coating sprayed front and back - it's just an extra layer of protection. Otherwise just fill any open (cooled) spaces with foam/neoprene. put some over the backplate on the back of the mobo (remember this area will get cold too) and then plenty of it around the socket.

You shouldn't have any problems cooling an E6600 but the Quad will be an issue. That being said, the quad will be an issue only over about 1.5v. The question will be how fast can you get it to go with just a small voltage bump. It's certainly worth trying if you already have the Q6600. Both Penryn's and Barcelonas are supposed to have much lower TDP's so chips available at the end of this year should be fine. Getting 6 months of Phase experience under your belt with your existing CPU's certainly won't do you any harm.

[jimmyz]

about insulating.

like loc.o said fill the socket with dielectric grease and smear the back of the proc. with it too. i use a custom mount but your prommy should have a heater for the back of the board etc. i use clear fingernail polish (buy a good brand as the cheap stuff flakes off easily). and over that i use plasti-dip. it is awesome and it will remove easily when needed. then i apply armaflex over that. so far i have insulated 4 boards and have never seen any condensation or corrosion. also once you lock down the arm on the 775 socket i fill the hinge and latch area with more grease as well as the divot where the latching arm goes. also i recommend arctic silver ceramique since it holds up well sub- zero.

plasti-dip:http://www.plastidip.com/consumer/index.html

and you won't need to insulate the video card unless you cool it with your prommy. the cold only really affects the area where the mount is and an inch or so past it.
staying with a dual core seems smart in your situation. use water on the quad rig and keep the dualcore for the prometia.
it should easily get you the 4ghz you want with the 6600 my 24/7 speed is 4.4 ghz with benching as high as 4644 (sometimes higher).

[DarthBeavis]

Check out this thread as it details the overhaul of my Vapo LS to handle a QX6700 (which might be of some use to u). Getting a new evap head and enclosure from Ssilencer. You can see upgrading takes some doing:

http://www.teamnexgen.org/forum/hardware-discussion/283-vapochill-ls-mod.html

They have a Prometia I think they said pulls -50 on a quad.

[Holst]

Putting an extra fan infront of the condensor on the front of the unit might help a bit. (did for me at lower wattages)
There isnt much you can do to a prommy to make it handle a larger load, appart from a major rebuild.

[dabhpr]

All great stuff, gents.

I will certainly be using the dielectric grease all around the socket and I'll just gotten back from Home Depot where I purchased a tube of "liquid electrical tape" - which I will assume is pretty close to "conformal coating". It states it's good from -50C to 140C, which should cover my needs.

"2long4u" - thanks for an excellent suggestion about running the Prommy for a couple of hours without the computer powered up. I'll certainly do that after I finish my overkill preparation (heh).

So: conformal coating (or equivalent), dielectric grease, some silicone sealant, lots of neoprene foam, electrical tape for wrapping the head, plenty of sealing string... am I leaving anything out?

Just want to thank EVERYONE for their kind and supportive words. This forum rocks, and it's all because of the folks that populate it.

Yep, it was suggested by jimmyz a few posts back. I already have it on the way 8^) a nice big 22 gram tube... heh.

I know that most of the Arctic Silver compounds need to be HEATED to "settle" and work their best. So, ceramique it is!

Thanks again...

Contrary to popular opinion: Crisco, Duct Tape, and KY should not be used when installing ur phase unit.

As I said, I'm worried your chip will overload the phase, and it seems like people seem to be agreeing with what I said. Check out the vapor phase forum and see if it includes what you wanted to see

btw....what you'd think of the vapor li 2000?:D

[dabhpr]

Got bad news from CrazyPC today: The socket 775 adaptor kit is on backorder and won't be shipped for about 3 weeks. Says it is a re-design of the adaptor.

??

In any case, I'll have plenty of time to test, prepare and get ready. I have now decided to definitely use the Prommy with the E6600, not the Q6600. Let's see what this chip can do on it, when the adaptor arrives...

Hi dabhpr,

I had my Mach 2 GT modded with a DSHC, SLHX, bigger condensor, Chilly1 head, a regass to R402a and tuned for 260w. A pretty major rebuild with the intent of overclocking a quad core.

I havent had the chance to use it yet as I moved abroad recently and my unit it still in Scotland. :( but I hope this gives you an idea of what you can do. :)

OK, I'm over my head here... what does DSHC, and SLHX mean? And who makes the Chilly1 head? What is it's advantage?

Could a local refrigerant expert do the regassing to R402a? How much of it is the normal load?

Is there someone that is recommended (in the USA) for these mods? I have some time now!!!

Just wondering....Why even bother buying a mach 2 in the first place if that was your plan?

It probably would have been cheaper too, not to mention you could spend the extra money on a nice case for it like the v2000b that can house it in the lower chamber, or you could a custom sized case that fits yours perfectly instead. Oh well

I think you should just pay chill1 himself to make you a phase, returning your mach 2 in favor of that will suit you far more

chilly1 makes the chilly1 evap:up:

And chilly1 I believe is in the us, but the cost of shipping, and getting the new parts outweighs imo simply building a phase from scratch because you can customize it yourself. But for someone that hasn't done much research I would recommend paying someone to do it for you instead

[dabhpr]

Hi again, all. I have an EVGA 680i rev A1 motherboard and I was reading that you need to basically insulate the motherboard an average of 2 inches from the socket for best condensation prevention.

http://img.photobucket.com/albums/v87/dabhpr/evga680i.jpg

(picture of motherboard above...)

This motherboard only has about 1/3 inch from the socket to the capacitors below the voltage regulators, and 1 1/2 inches on the left side, and about 1/4 inch on the right side to those two voltage regulators... There is nearly 2 inches to the first memory slot, though.

I am not comfortable putting insulation OVER the voltage regulators, which get really hot... will their heat output negate the need for insulation there? Or do I just cut out the area they occupy and put a form-fitted foam block in place anyway?

[jimmyz]

cut to shape around the components marked r50.

that looks like a good size alittle big on the northbridge and ram sides but pretty good oter places. and don't forget about the back of the board also.

True, but at the time the standard unit was a good option for me (before dual cores came out), I got a custom case for it for a good price, and was unsure about "some bloke on a forum knocking one up for me". :shrug:

I wouldn't advise anyone to buy one now though. :down:

Am I to assume I should also forego putting conformal coating on the R50 regulators? I would think their prodigious heat output may burn the coating...

[[XC] 2long4u]

SLHX - Suction line heat exchanger. DSHC - I don't really know but the D would be the discharge line.

Ahh makes sense then, for a single core even crappy phases are amazing

just wondering....what didn't you mod on the phase?

[weescott]

lol, the compressor, the electrics, and the rear fan. I'm happy with the noise levels of the NL11F and didn't want anything louder.

dabhpr,

DSHC = De-super heater coil.

A regass could be done by a local refrigerant expert, I would probably wan't someone here to do it though. The Chilly1 head should knock about 5c off the standard Mach 2GT head but you are as well getting it done at the same time as a re-gass.

A DSHC, Chilly1 head, and a regass equates to roughly 20c lower temperatures.

A regass to R402a alone equates to 10c lower temperatures.

IIRC the Mach2GT is only good for about 200w of heat with quad core putting out c260w.

geez, so you basically built a phase from scratch with the exception of like 3 or 4 parts (including tubing stuff etc). You might as well have built a new phase and sold the gt for about $500 or so on ebay

It actually worked out cheaper to re-build the unit than to sell the Mach2GT with custom case (which I didn't want to sell anyway). Than to buy a new custom unit. Plus less the hassle of ebay and extra postage.:up:

Nope. I don't want to go into figures here or start pimping the person from here who did the work. I'll show it off once I get it shipped out to me in Borneo and a new rig built up. :up:

Hmm.

I know this is a bit off topic, but as I don't have much money from the student budget I have, I'll need to buy used parts, do you seriously think it's that bad to do so?

[weescott]

It all needs pressure tested so I don't see why not.

[AliG]

Cool, because I know of a local used hardware shop that I can get the compressor, condensor, and even a vacuum compressor (for purging out the impurities) for dirt cheap

[weescott]

It's the experience, know how, and qualifications that are un-quantifiable. If you have the know how, source of parts and are legally allowed to work with refrigerents then all you need is this forum! :D

[SLI_Fallen]

Hmmm. Wondering if this is my problem.

Running a QX6700 on an EVGA NF68 680i board with a Mach-1 prommie.

I can personally attest to the LGA 775 kit needing a redesign as the plastic clips that mount the metal holder were totally off. I modded mine and held it in place with seal string and so far it seems fine. I just sealed the block stock on this MB and I have no issues with leaks/ice/ect that someone said you have to seal up beyond the "normal" cpu mounting area.

However I do have a problem.

My unit is hitting +40 and shutting down (with err4, CPU temp) error on initial bootup after being off, say overnight. If I wait 30 seconds and try again, it starts cooling and once it hits -33 it releases the reset line and the computer boots. This is a new upgrade for me from an AMD FX-60 but the system is 100% totally stable prime95, superpi, you name it at 3733mhz@1.4 v. the reported temps are actually BETTER than what my fx-60 was pulling and that is what is odd.

I never had a initial boot temp issue on that CPU. and according this site (if it to be believed):

http://www.extreme.outervision.com/tools.jsp#cpuoc)

My FX-60 was pulling way WAY more watts than this quad is now.

Any wisdom on what is really going on here?

[AliG]

It's all about the evap, I talked to kayl about his mach 2 mods, and regassing, putting a bigger compressor (3/4hp, which is way more than enough) and condensor helped with the temps on dual cores, but it still could not handle quad, but as soon as he put on his kayl block, it worked like a charm (he even got to 4.9ghz on his block).

I'm guessing a better evap should be all that's necessary to at least get reasonable temps and stop it from shutting off, but you probably will also need a stronger compressor
