Meeting @ Castagnito (Asti, Italy) – 4/5 August 2010

Wednesday and thursday of the past week I and my 2 friends 7ornado (Simone) and The King (Marco) meet at Castagnito (Italy, near Asti, a place famous for wine and truffles).
We had 100 litres of LN2 and a lot of hardware.

7ornado and the king used:

  • i7-975
  • my A-Data 2133X MNH-E-Hyper
  • HD4870 Sapphire 1 GB
  • the good old Enermax Galaxy 1 KWatt
  • ryba CPU and GPU pot


I used:

  • 2x i7 950
  • DFI UT X58-T3eH8 (bios D615)
  • Kingston HyperX 2000 cas8 MGH-E-Hyper
  • GTX 280 Asus
  • P&C 1200 Watt
  • Guglio CPU and GPU pot


To be honest we planned to test a good 7600 GT already vmodded, we fired it up on a RE but this crappy mobo died at default setting all at air and also killed the video card.
We went ahead, while I focused on test the 950s my 2 friends start to test the HD4870 with their rig.
We expected a bit more from the CPUs, the 975 is pretty maxed out at 5.2 GHZ and the 2 950s work exactly the same, 5150 MHZ no 1 MHZ more.
The first 950 was really hot, the second one is more cold but scale really crap with the temperature…at least all of them have cold boot around -90° Celsius, cold bug at -130° C and all of them going crazy with vcore higher than 1.6 volt.
For my 3d test i chose the coldest one, it have lower coldboot (5/10° less than the other one) and eat less LN2.
I also haven’t the retenction system for my GPU pot, then I tried to use a vise but it was too small…luckily (not for the VGA 😆 ) I found some ties and with a bit of intelligence (lol, it’s not the best word to describe what i did… :D) the GPU pot was mounted.
Cause I’m too lazy to use neoprene and I don’t like kneed eraser I used only paper for insulate the card.

EVGA, 975 EE, thermos and our motto (don’t think that there is an english translation of it, BTW the sense is “do your best with what you have and don’t give up”).

DFI, 950, GTX 280…all seems normal but when I’m around nothing can be normal

Wensday at 11 pm we finished the first 50 L, then we had a shower and we went to a mojito party.
After some mojitos (never had a mojito like that, at least half was rum) and beers at 4 AM we went to sleep.
At 7.30 AM we get up and after some coffee and redbull we call the LN2 man because we needed another 50 L.
We put the dewar in the car and in 45 minutes we did 70 km (lol, this FIAT Punto 1900 CC JTD is crazy, 210 KM/H are damn easy on a road with limit at 90 KM/H).
At 12 oclock after the lunch we was ready to go, we benched until 10 PM when the LN2 was finished.
Except for the dead graphic cards and crappy CPUs all was good and we had a lot of fun.

Not a great results but I’m quite happy because I get all out of the rig and for the first time I use 2 pot alone and it was easy,
I din’t had any problem to keep the temp in the sweet temp range and at the same time bench.


Thanks marco for the hospitality and for these 2 crazy days.

Back in real business – round 1

Nothing special here, no WR or something like that but today finally I had 10 litres of LN2 to try my i7 950.
I’m happy because it’s been a long time since I had a good bench session at LN2, in the last six months I lost my time with p4 (8.1 GHZ then the RE died….), phenom 1090T with a crappy MSI 890FX and another bunch of rubbish…
Now seems that the luck is coming back, this 950 works pretty well.

config:

  • i7 950
  • DFI UT X58-T3eH8 (bios D615)
  • kingston HyperX 3×2 GB 2000 cas8 MGH-E-Hyper
  • ASUS GTX 280
  • WD scorpio 160 GB
  • P&C 750 watt
  • Guglio’s CPU POT rev 2.0

I’ve this graphic card from 2 days, then I didn’t have all the time to test driver and tweak…I’ve tested only the max benchable frequency at stock cooling.
There is a lot of room for improve the score.

BTW in this bench session I’m focusing on the CPU, the VGA need more testing and some mod before run it at LN2 and do some damage on HWBOT.

today here was damn hot…

extreme air cooling

Highslide JS

with the first 4 litres of LN2 I can reach 354k am3 with CPU at 5150 MHZ…not bad at all for the first touch with this CPU.

Highslide JS

When all was going well I tried 24x multiplier…not a good idea, in fact the cpu was going crazy and stop to work for 3 or 4 hours.
I need to refill the dewar and start the round 2.

i7 950 + DFI UT X58 + HD4890…pwnage incoming

Few weeks ago I got an i7 950 from ebay.
The first impression was good, it has a really strong IMCH and it’s damn hot…then probably it has low cold bug.
Before put it under LN2, as I always do, I’m testing it with my single stage phase change (for more info look at Cooling section).
The maximum core frequency that I can reach isn’t that good, but I think that with more cold it will give me tons of others MHZ.

config:

  • i7 950
  • DFI UT X58-T3eH8 (bios D429)
  • kingston HyperX 3×2 GB 2000 cas8 MGH-E-Hyper
  • Sapphire HD4890 Atomic
  • WD scorpio 160 GB / kingston SSD now 64 GB
  • P&C 750 watt

thx Sapphire for this great VGA and Kingston for the SSD

*UPDATE

It isn’t the best rig for 3dmark 01, however I gave it a try.
The efficiency and the score are quite good…100k is not that distant.
