dehumidifiers are cool, i got an old one sitting in my room begging to be modded to cool a pc, with perfect size for a mobo (once i remove the 2 huge fans) and then the perfect size for the CD-rom/psu where the water tank thingo used to be (the drip catcher).

Heavy_Equipment · 09-06-2002, 12:36 AM

Two things,

First, you need the fan (fans?) in there...I just wired in a rheostat to control the speed (noise) of the fan.

Second, for the very reason you need the fan...HEAT, mounting your MB inside the chiller is a bad idea.

The exhaust air coming out of mine (the reason for the fan) is around 40C. It's above 50C at start up.

You'll be wasting a lot of cooling effort, running it inside a 40C box. My PC case is mounted on top of the dehumidifier, so the hoses don't get too crazy, but the temp on the rest of my MB and goodies is ambient.

HeavyGear,

Did you just bend the 'cold coil thingy' over into some water?. most I've seen pics of are done like that...

Heavy_Equipment · 09-06-2002, 04:31 AM

MadCat...

Yes, I just bent the tubing, so it is now submerged in a res. I don't have a camera, so no pics of mine, but here's #Rotor's which is very similar.
I actually took some inspiration off this one, although mine doesn't have the pump submerged, and is nowhere near that tidy.

pHaestus,

what is wrong with OCZ (besides the price) and the fact that it may not be true 3200 (since when I was putting this rig together OCZ was the only game in town with 3200...)

jamicon · 09-06-2002, 08:45 AM

i realise that the air would be hot, but there is enough room to mount a cowling and everything so it is basically 2 seperate areas, the cool area, and the hot area(which would have the hot radiator, and the compressor.

i took everything appart in my dehumidifier, so its only the cooler now, but then when i look at the condenser, it seems a little small, its only 100mm Diameter (4") wide (its round, not oval).
it says the dehumidifier is rated at 0.9KW.

OCZ have pulled some very shady tricks in the past, selling RAM with different chips than stated and gluing on a heatspreader with a big 'VIOD IF REMOVED' sticker on so's you could'nt check it!. also alot of their RAM would'nt run at its rated speed. they've done this kinda stuff more than once, as well as trying to do it under different aliases(I think).

Some people have OCZ RAM and have no problems, but the ratio of happy/unhappy customers is beyond the pale

. the long and short of it is thrice bitten ~ many times shy

. they've earnt themselves a bad rep' with the overclocking comunity :shrug: ...

The sheer amount of complaints I've read about thier stuff has stopped me from ever buying it, I see they're selling DDR 3700 Cas2 RAM now

, might be good for running at 166

...

tokamac · 09-07-2002, 10:38 AM

yea I haven't had much luck pushing the FSB... so I just made the jump straight to 166 (cpu fsb).... maybe I ought to go straight for 200(cup fsb)... (the memory is running at 166 too). I always thought it was my video card crashing the system... I want to work out the hot mobo voltage regulators before I push the system too much further...

The reason it is doing wierd things at the higher multipliers is that your board cannot do them. Simply, any multiplier after the 12.5/13X will result in a LOWER multiplier. This is normal, though. If you look at the unlock procedure for the 2200+ and higher you will notice that you have to do some fiddling with another set of bridges altogether. What the chip does is do the multiplier setting ON BOARD. When it sees the lower multiplier settings and the bridges in the L4??? (I can't remember off the top of my head) are set opposite of what they are stock in the 1800+, it starts stepping up from 13X to 20.5X (again, if I remember correctly), even though the board shows 5X to 12.5X. That bridge on the processor tells the processor what to do with the settings from the mobo. Any setting higher than that 12.5/13X setting is emulated. In other words, I'm not sure if you can get the higher multis from the 1800+ chip (I'm tempted to do it on my 1900+ but I'm a bit shaky about cutting bridges on my proc with a dremel, especially if I don't know if it will work), but it iinvolves more than a simple unlock if you can. Oh, and if you're getting the multis that you were describing in your table, your unlock is fubar. Do it again.

airspirit · 09-07-2002, 11:26 AM

Oh, and a generalized way of telling what is f*cking your overclock is as follows: if it doesn't boot, it is your memory or proc holding you back. If it boots but dies when it switches resolution in windows, it is your GPU. If it boots and says "No boot record found" or "Your hard drive is f*cked", your hard drive is f*cked.

Please don't take that seriously.

Brad · 09-07-2002, 04:20 PM

I've had 'ntldr' is missing due to overclocking a little bit too high, once I dropped down a couple of mhz it all went back to perfect.

another way to see if it is ram or cpu that is limiting you is to adjust your ram timings slightly, to see if the instability gets worse or doesn't change. with your ocz stuff, I'm willing to bet your machine will running into ram problems first

jamicon · 09-07-2002, 07:51 PM

the 'ntldr' problem is because the overclocked PCI bus makes the hdd run above spec, and it cant handle it

How about some of the=ose 'Tiny BGA Copper/Chromeplated' RAM sinks?...

tokamac · 09-08-2002, 08:52 PM

um... is that a brand? because BGA is a fabrication/chip attachment method... and plus chrome never made anything go faster...

Heavy_Equipment · 09-08-2002, 08:56 PM

MadDogMe means these.

MadDogMe · 09-09-2002, 04:11 AM

Yep!, them!!.
Its the BGA chips they're made for, hence why I thought of them, not too big for your Mosfets

.
Actualy I think it's Nickel plated , not chrome. I think it's to stop them tarnishing, plus they're good looking

tokamac · 09-09-2002, 05:40 PM

ok... nice, thanks for the link. I was looking at some that were annodized aluminum, (free cause I pulled them off some other pieces of equipment I have laying around

but I like the copper ones better... I will let you know how it goes... right now I am pretty sure my limiting factor is either the CPU, mobo or PS ... (cause when I go from 11 to 11.5 it will post and not quite get all the way through the IRQ device list page) so I am either pulling too much power (very probable considering my weak ass powersupply) or maxing out my chip or pulling too much power through my motherboard (since it has to step the voltage down from 5V to the lower voltages required by the chip) ...
