Swiftech MCP655
HWLabs 120mm BLack Ice Pro
Sapphire X1800XT
Cooled by Artic Cooling Accelero X2
Soundblaster Audigy ZS
Muskin Redline XP 2GB(Infineon CE-5)
2x120mm fans

Wow dude! That is quite a setup you have! What are the temps like?

cadaveca 11th April, 2006 03:15 PM

current load temp @ 3ghz, 1.5v, is 31c, while water temp is 30c. The 120mm radiator is not quite enough cooling for the cpu tho, and i am noticing a slow rise in temps. I tried priming overnight @ 3ghz, 1.45v, and woke up to a frozen windows boot, water temp @ 48c...cpu temp must be a bit higher.


This little escapade has proven, to me at least, the the temps reported on this board are false. I'll be taking everything apart later today and mounting a thermal diode next to the cpu die, to try to get some more accurate readings.

Oh, and case is a NZXT Lexa.

I'll be moving the watercooling over to the x1900 Crossfire rig at a later date...this test was to confirm/deny the plausibility of adding those two infernos to the cooling loop...looks like the next rad is a BIX III.

I'll be putting some ice into the coolant to lower temps further, at which point i know 3.3ghz will be doable...last night i had the water down to 4c, running 3.35ghz @ 1.78v.

Accelero X2?

What are they like?

raphael2040 12th April, 2006 01:31 AM

Whoa.

Nice.

Are you intending on cooling the graphics card?

Okay, i guess...idle temps same as stock, pretty well, and becasue i have been playing with the cpu, I have not had much time to test as of yet. Nice and silent and far lighter than the stock heatsink, that's for sure. I'll be starting a thread on it later, once i get the card installed in the other machine, as i have just loaded the x1900's up now that i know i will be able to hit my goal.


Raph, I will put up much more info in the coming weeks on the vid cards, but I have decided to open my store during the dogshow this weekend, so i have some work to do before i can devote such time.

Updated system config:

Opteron 148
DFI RDX200
Cooled by DangerDen A64 TDX
Swiftech MCP655
HWLabs 120mm BLack Ice Pro
Sapphire X1900 Crossfire
BBATI X1900XTX
Soundblaster Audigy ZS
Muskin Redline XP 2GB(Infineon CE-5)
2x120mm fans
Enermax Liberty 620W
Seagate 7200.9 SATA 160gb
LG-4167


MY goal of 3.3ghz is so that i might break 10k in 3dmark06...

Here's cards @ 650/774(XTX speeds on both cards:

http://service.futuremark.com/compare?3dm06=240688

Will be doiung singlecard scores and pics later as well.

I'm looking forward to it, good luck on your quest Cadaveca :thumbsup:

Can you use something like MBM to read the CPU diode directly, instead of using DFI's utility (which I assume is what you are doing)? The reason I ask is because from what I've seen the BIOS engineers usually program a fudge-factor into the BIOS code to offset the temp readings in the hardware. A program like MBM can reset the hardware registers so that there is no fudge-factor. Once that is done, the diode should read with +/- 5C of actual temp (and for the temps you are at, might actually be fairly close to accurate, as the +/- 5C variation applies across the entire 0-70 C range, typcially). Getting more accurate than that will require some kind of calibration, unless you use an external temp meter and thermocouple combination with a known accuracy.

I'm using systool. MBM reports the same temps. But you said reset? how do i do that?

Thermal couple on Fluke multimeter reads 36c on the bottom of the block, and reported temps are 30c(this is under load of course)

I don't rightly remember now, but I do know that MBM provides the ability to calculate an offset, and I believe it is part of that stuff. Take a look in the MBM help files.

Great quest, and hope you get there and 10k on 3D06 would be good to.

Placing the pump into the case...looks like MR Dremel is coming out. I must remove the material inside the black line.

Also had to remove some so the rad would fit inside:

cadaveca 13th April, 2006 05:04 PM

The system is up and running now, and I'm posting here from it.I've got the watercooling for the cpu mounted just fine, however i need to sort out the hose-path for when the next rad and the gpu blocks arrive, as well as decide on proper fan placement. more to follow later.

HEre's how it looks so far, but please bear in mind it's far from complete!

cadaveca 13th April, 2006 05:14 PM

current load temps are displayed as 29c by various software, 33c by both thermal probes taped next to the cpi die(the fluke reads 33.4 tho). I assume that the actual die temp is abt 8-10 degrees higher than that.

Gizmo 13th April, 2006 05:28 PM

Do you still think you'll be able to hit 3.3 GHz on water at ambient, or do you think you're gonna have to ice it down?
