Re: Subzero prep old hardware and new(SS,subzero chiller)
For the sapphire 4890 you're going to have to do a voltage mod. There is no software control for that card and if it's like mine the default voltage is 1.28v which you might just be able to get 1000MHz vantage stable with if you're lucky.
Re: Subzero prep old hardware and new(SS,subzero chiller)
Think i must do v-mod of some of them like 8800ultra,8800gtx,8800gts,280gtx,275gtx,285gtx, 4890 sapphire vapor x to get all out of them. I have soder and iron already and some trimpots. only letdown is my soldering skills on pcb
.
Do you have any mod guide for 4890 vapor-x ObscureParadox ?
Btw 2 8800, 1 ultra, gtx280,gtx285 is prepped for subzero. will mod the reference coolers to make uni sinks for them.
Did not like the 280 vrm/mem design what a mess.... hardest card i have seen to watercool with out full cover block

Yeah I do, I'll find the link for you when I'm on my PC later 

Re: Subzero prep old hardware and new(SS,subzero chiller)
I am making some progress. with old Nvidia cards. Only v-mods left now.

Cards are 2 8800gtx,8800ultra,gtx280,gtx285
Did some unisinks from Ref coolers for vrm . Was easy to solder off heat sink from base plate off Ref cooler.
Takes 3 min each ref cooler with butane torch. Most time is cutting for (gpu only) Waterblock. Took about 1 hour for 5 unisinks.

Re: Subzero prep old hardware and new(SS,subzero chiller)
Yes most likly. Have order a lot of trimpots (the ones i will need) and a high quality soldering station( Aouye 950).
have already flux and soldering, cleaning etc.
All mods seems to be on overclock.net.

Even for 4890 vapor x.

Re: Subzero prep old hardware and new(SS,subzero chiller)
Today was v-mod day



Cards moded for more v core is 2x 8800gtx 1 8800ultra and one gtx285
The gtx 280 dont nead hardmod, softmod allow 1.6-1.7vcore.
500ohm trimpot 8800gtx,ultra
100ohm trimpot Gtx285
Next cards to mod 2x 3870, 4890 Vapor X.
Have later cards to mod that not arrived a gtx 275, another 8800ultra ,2 8600gt,8800gts 512mb,4870x2.
One thing for shore it takes time to mod when have big hands

Re: Subzero prep old hardware and new(SS,subzero chiller)
Nice work Pulse 
When they say VR to ground where is the ground/GND??

Re: Subzero prep old hardware and new(SS,subzero chiller)
Ground on what Nick trimpot or card?
On 8800gtx/Ultra or gtx 285 card?
On 8800 i used ground on extra power connect.(2) Middle stick on trimpot.
(1or3) pin on trimpot to resistor on pic.You nead trimpot 500-400ohm
So cable on resistor to vr(Trimpot)pin 1or3. Second cable from ground pin2(Trimpot) to ground card( I used extra power connect ground on my cards)

285gtx is a harder mod remove resistor very little space you nead good tipp on solder iron.

Good guide of Crotale
You nead to do as picture and right order with cables. Trimpot 100ohm.
I used solder station for resistor removal and solder iron (20w) for cable
I destroyed a IDE cable to get solder cables. They are small and easy to solder.
Hope it helped Nick

Re: Subzero prep old hardware and new(SS,subzero chiller)
Ok did the Amd(ati) cards tonight.

2 3870 and one 4890 vapor-x

Now if i could get the 5 cards that has not come yet and nead v-mods...

Re: Subzero prep old hardware and new(SS,subzero chiller)
After some time away (a lot of work) i did my best auction buy yet for lga 775 platform.
i payed 150 pounds. The cpus were tested. Oc yet to come...

A big photo of the stuff i got

54 cpus
10 = Athlon x2,sempron, opterons (this i got for free)
20 = core2duo varios cpu e6600 and better
10 = wolfdale e8500,e8400
20 = core quad q6600,q6700 and better
4 = xeons quad

20 ramsticks of different kind ddr2 (for free)
Now i have 80+ Lga 775 cpus in total.
So when all is ready 150+ cpus and 50+ gfx to bench to gain some points for Team MLG

Re: Subzero prep old hardware and new(SS,subzero chiller)
My flights are booked, I'm coming over!! 
How's that beast of a cascade coming along?

Re: Subzero prep old hardware and new(SS,subzero chiller)
My guess is 1-2 month away. So i got plenty time to do cards ready for subzero. And finishing pump station.
The frame work for pump station is done. missing tank(12-15l) and tubes to soldering it clear for insulation.
I got a felling the pump station gonna weight 60kgs when done. But it gonna give a huge improvement in:
1.Flowrate,pump pressure at coldwater (3st 220v pumps power full with magnetic drive for impeller)(no heat in lope)
2.increase efficiency of Hx in chiller = colder watertemps (flowrate)
3.Water circulate in chillers without pressure drop and flowrate reductions.(piping in station)
4. 4 inlet and outlet on pumpstation = easy to use 4 universal gpu blocks without any kind of bridge.(piping in station)
5. With 25 ltr of water in chillers and tank = Less stress on compressors = less loud = more water to heat up.
It gonna be alot of soldering before done tho.
So your flight ticket can wait Nick or you will be disappointed

They take some time to insulate. So 6 cards and 4 motherboards and pumpstation and cascade before bench fun

Re: Subzero prep old hardware and new(SS,subzero chiller)
Very nice! Where do you get them all?
Let me know if you are willing to sell some

Re: Subzero prep old hardware and new(SS,subzero chiller)
Ebay and tradera is best hunting ground for gfx cards or cpus.
Re: Subzero prep old hardware and new(SS,subzero chiller)
You are so much crazier than I am pulse.
Im getting an SS in very near future aswell so can go subzero much more often and especially with old cards.

Re: Subzero prep old hardware and new(SS,subzero chiller)
Good idea Lummi. SS is powerful enough if you have god cpus. And subzero will save you some money vs Ln2
