My first cooler project: Xp1700+@1922Mhz

Heavy_Equipment · 05-24-2002, 08:51 PM

I bought an Xp1700+ Wed., an Eheim 1048, a 256 Samsung PC2700 and a used Kenmore dehumidifier (R12) today.

I could only get it to 1759(11x159.91 @ 1.85v) Cas 2.5 Normal with PC2100 and just my water setup, and it was running around 44C under load.

I am now doing 1922(11x174.73 @1.96v...not unlocked yet) Cas 2 Fast.
The sandra scores are getting me aroused.

The chiller is only half-assed together, I could only find a rectangular plastic juice jug around the house that just fit over 3/4 of the coil assembly...top 1/4 exposed, and 4 loops of the coil outside on one end.

I wired in a rheostat and mounted it in the front panel (looks like the factory put it there

), so I have 100% fan speed control. (Thanks #Rotor)

I haven't done any condensation proofing yet, so I haven't gotten too carried away with cranking on it yet, and I'm keeping my cpu temps about 10C above ambient for now. (ambient is 19C with the window open...cpu is at 30C right now (MB probe) with UD running)

The temperature setting is at half, and my fan is roughly 1/2 speed, so I'm happy. The one quick shot I gave it at full fan/coldest dropped the water (50/50 Prestone antifreeze and water) to -1C (dropped a thermometer in the res) in about 5 minutes, the cpu temp was dropping steadily, and I turned it back at 14C, because I could see my waterblock covered in droplets. That was with UD running. This is gonna be fun.

Update:
I settled on 1914, because it wouldn't run my torture test for more than 10 minutes at 1922, it would hit 32C and lock up. It needs to run Toast, Ud Think, and mp3's together for a few hours before I consider it stable. Can't wait to get this chip unlocked. Gonna shoot for 9.5x200.

i have an old dehumidifire.. what kinda stuff did you have to mod in it? and basically what is it used for?

and pics !

I put the coil in a reservoir. (well, still working on that part) Basically, it replaces the rad in the water cooling system.

I don't have a camera, sorry, but there are pictures of the same thing (well, not the SAME thing, mine doesn't look half as good

)at #Rotor's site, he even sells them ready to go.here

nice overclock there! are you going to try cranking the voltage up further, you might get 2ghz out of it then

Heavy_Equipment · 05-30-2002, 11:48 AM

I had to go away on business this week, and I've been itching to get back to this. lol

Well, when I left Monday morning, I was just getting it to go into windows 98se at 2002 mhz. It crashes when my temps climb higher than 32 C.

The plan now is to get my processor a bit cooler. The waterblock I'm using is my weakness. It's a good block, don't get me wrong, Joe's waterblock round up even showed that, I just need better.

My water is a constant -10 C, so I know with the right block/flow rate I can shave off the proc. temp. I am in the process of buying one of #Rotor's blocks, and I'm looking for an XP with an AROIA stepping as well. If all else fails, then I'll have to up the voltage with a mod, which I am trying to avoid if possible. I'm gunning for a 2Ghz XP with a 200 fsb. That's gonna be hot enough without throwing the voltage to it.

I'll keep you posted.

what voltage is the 2002mhz at? A friend of mine got 1930mhz with 2.05v, now it's 200 x 10 at 2.35v and going just fine. He is phase change, with -16c water temps and 14C cpu temps

Heavy_Equipment · 05-30-2002, 03:43 PM

That's with 1.96v.

The version 2.1 Xp333 has a "+10%" feature. 10% of what I'm not sure lol. I have it set to 1.85v, and the +10% enabled...giving me 1.96.

2002 mhz is the same as 1925 mhz right now...as soon as I cross that magical 32C line, it locks up. I figure I need to drop 5C for starters, then I'll see where that gets me.
