Phase Change this! Mach I

I got myself a Prommy, nice bargain

Yesterday I started it up & lookie lookie some nice ice!

Today I have an Epox 8RDA (ctgilles) and a TbredB XP1700+ to play with.

I started of rolling the motherboard in a nice little package!

seems pretty decent

Now the evaphead installed

all ready to go ->

After bootup I went straight into the BIOS

CPU temp of 18°C that dropped after 10min tot 11°C
hmmm.. the Prometeia read -46°C

bad contact ->

No problem, following the guidelines on the prometeia website I put some extra spacers on each screw.. put it all back together

CPU temp of 9°C
hmmm still some spacers left.. I start screwing them tight again..

I'm just too damn powerfull

luckily I have 1 spare screw (thankx to calantak)
might try it again later.. this night

you made a major mistake there
after you've mounted the evap for the first times, remove it to see whether it makes good contact. same stuff when mounting a new heatsink, you'd never know something goes wrong

(cf.: SLK800+coppershim doesn't make contact with die.
beki mounted his alpha for the first time. he didn't check it, and due to some rubber feet on the hs it didn't make contact either and the proc died)

btw: nice to see you going subzero

well it's game over now, cause the screw is stuck

Quote:

Let it settle for a while, then unscrew and unmount the coolinghead again.
If the imprint of the core looks like on the picture here, the pressure is insufficient, and needs to be increased.

This is done by adding more spacers to the mounting screws, just below the screw head. Currently 5 spacer rings are placed as standard, but up to 4 or 5 extra spacers may prove to be optimal on your particular Prometeia Cooling system.

have to dissamble the whole lot, lateron

cant wait that long

reinstalled, again 18°C
maybe it is the position of the head & the evap..

jmke · 31st May 2003, 15:44

cpu is @ 9°C in the bios after a couple of min. with vcore @ 2v

XP1700+@2500Mhz

200x12.5

can't get higher
how do I unlock the higher Multipliers?

is this the correct way to do so?

Quote:

Cut the 3rd and 5th bridge of L3 to unlock all the multys.

If i'm not mistaken you can cut them while *shortcircuiting* them. 5V + needles will do the trick.

call me stupid, but I find this page very confusing

that's the spirit !

Besides, it's way tooooo crowded if you wanted to go out

Unlucking all multi's is done as quoted. I saw that info on several websites, in different threads ... haven't done it yet, should be mucho simple.

going to install the whole thing into my Chieftec, because I'm convinced the position of the head isn't optimal at all

I still have +0°C temps @ idle, with enough contact

to unlock higher multi's you'll have to wiretrick it (only multi's 13 and higher available!)

jmke · 31st May 2003, 16:42

When I'm able to obtain -0°C temps then using 13x will be no problemo

31st May 2003, 16:49

Changing an 8X Bit Value LO to a HI, to access 13X and higher from default Multipliers = 12.5X and lower.
Tbred's rightmost 5th L3 bridge will be Closed. Palomino's L10 bridge pair will be Closed/Open L to R.
General solution is to reset that signal circuit HI. Options:-
1:- Tbred, open the closed 5th L3 bridge.
2:- Palomino, change L10 bridge pair from Left/Right Closed/Open to Open/Closed.
3:- Tbred and Palomino, solder wire to socket AJ27, connect to Vcore thru 100 ohm resistor, (remotely switch/toggle).
4:- Tbred and Palomino, connect AJ27 socket hole and nearby AH26 Vcc/Vcore socket hole with fine wire u-loop, replace CPU. Or connect the "bases" of socket pins AJ27 and AH26 with conductive ink. Note risk of accidental Vcore short circuit since no current limiting resistor as in 3:- above. See socket/pins pics for all locations above.
