Time for a new computer

Hello everyone.

It's time to change my old computer, this one having an AMD Athlon XP 1800+ on socket A mainboard, 512MB DDR@400MHz, GeForce4MX on AGP8X and a defective HDD Maxtor 40GB@7200rpm.
RAM quantity became insufficient for modern applications, which are in fact the same as were 6 years ago: Windows XP, firefox, Bitdefender IS, and utorrent since 3 years ago.
Other applications doesn't count due to the fact that they are used only occasionally.

After many hours spent to choose the right platform (the producer I wanted from start was Intel), this subject became so much time consuming that I had to cut the story short.
Only 2 main reasons counted for me in the end: a computer which will be silent and versatile, or powerful and noisy.

The LGA 775 platform is almost dead (looking into the future, and not so close one), so the battle is only between LGA 1156 and LGA 1366.
There are so many pros and cons for each platform that I'll point only the important ones.

LGA 1156
+ powerful i7 processors (i7 860 on LGA 1156 is equal or even better than i7 920 on LGA 1366)
+ better power management
+ lower TDP (consumed energy and exhausted heat)
+ i5 processors compatibility (another lower TDP advantage)
+ mainboards have the same accessories (sound, LAN, storage, connections) as bigger brothers and sisters
+ same or even better overclocking potential
+ memory controller integrated into CPU as i7 on LGA 1366 has

- integrated PCIexpress controller in CPU means: because only 16 lines of PCIex are available, a SLI (Crossfire) sollution will have 2 x 8 lines, instead of 2 x 16 as on LGA 1366
In real life, this thing doesn't count so much, only 2-3% of performance drop were seen.
And 3 way SLI (Crossfire) is available.

- only dual channel configuration for memory instead of triple channel on 1366
This means that LGA 1156 have a maximum capacity of 16GB instead of 24GB as on 1366.
But how many of us are installing that much and use it indeed?
So, for the commons, 4-6GB are enough.
Even 4GB are enough (dual channel kit of 2x2GB widely found).

This is the platform "silent and versatile".

LGA 1366
+ powerful i7 processors
+ overclocking potential
+ memory controller integrated into CPU
+ triple channel memory
+ PCIexpress controller is not integrated in CPU but allows 2 x 16 lanes in SLI or Crossfire. 3 way or 4 way SLI (Crossfire) is possible.

- not so better power management, mostly when overclock is used
- high TDP (great consumed energy and exhausted heat)

This is the "powerful but noisy" platform.

Its seems that LGA 1366 have more pros than cons, but those cons, believe me, count that much.
You need a good power source with higher wattage.
You need more fans and a case which has a good air flow.

Beside more energy consumed, it's creating also a great noise. So only teenagers and singles are allowed to play games, the rest have to obey wife request for a good sleep. But, even this request can be satisfied, if other satisfaction is involved before...

But even that most components have solid capacitors, a constant 40-60-80 degrees Celsius in the case is not good for long term use.
And not so many have funds to change the computer over 2-3 years or so.

That's why I choose the 1156.
I am not playing a lot, mostly office applications, but image/video/audio manipulation is performed sometime and i7 860 is powerful enough.

What I have chosen so far: (lets hope that retailers have these on stock)
Mainboard: MSI P55-GD80



Processor: i7 860



Memory: Kingston 4GB kit (2x2GB)



Video: MSI GTX 275 Twin Frozr



Storage for OS: Intel SSD 80GB X25-M (or maybe 2 of them in RAID 0)



Storage for documents: 2 x Western Digital 1TB Caviar Black (planning for other 2 of them - total of 4 in RAID 10)



Monitor will be for the moment a 19" one, but since a GTX 275 is involved, I have to look for a good 24" TFT monitor.
Since I have two DVD optical units, one will be used from the old computer (ATA).

Total power needed is expected around 350W for daily use but since I am planning for massive storage (RAID) and another video board, I think that I have to look for a higher wattage.

Peak power needed for:
[x] overclocked CPU up to 3.6GHz and 1.5V
[x] 4 stick of 2GB DDR3
[x] 2 video boards GTX 275 in SLI
[x] 4 HDD 7200rpm SATA in RAID
[x] 2 SSD in RAID
[x] 1 HDD and 1 DVD ATA
[x] 2 devices drawing power from USB
[x] 6 fans (2x120, 2x120led, 1x140, 1x250)
[x] additional PCI, PCIexpress cards
[x] fan controller
[x] 100% TDP
[x] 100% peak load
[x] 25% capacitor aging (even that most of the components use solid capacitors, power sources are not)

= 857W
Taking into consideration the 80%+ performance rating of the power sources, a total of 1100W are needed.

That was the peak load.
The most common used power will be with 85% TDP, 90% peak load and 20% capacitor aging: 715W.
And with power loses, 900W.

Taking into consideration the following scenario of daily usage (SLI and other additional components will have to wait for a while):
[x] no overclock for CPU (power save features and performance scalability enabled)
[x] 2 stick of 2GB DDR3
[x] 1 video board GTX 275
[x] 4 HDD 7200rpm SATA in RAID
[x] 1 SSD
[x] 1 DVD ATA
[x] 1 devices drawing power from USB
[x] 5 fans (2x120, 2x120led, 1x140)
[x] additional PCI card
[x] no fan controller
[x] 85% TDP
[x] 90% peak load
[x] 15% capacitor aging

= 433W
With 80+ performance = 550W

Two components I have left out on purpose, especially because they depend on the other components:
1. case (depending on the height of aftermarket cooler for CPU, length of video board, wire management and HDDs cage for storage and cooling)
2. power source (depending on the power consumed by every other components).

When all the details will be clear, I will post my decision for the case and power source.

If you know other details then me, tips and tricks, don't hesitate to comment, I need your good ideas for a silent, ventilated and powerful computer.
Yes indeed, all those three features are a must.


!!!UPDATE!!!
I have chosen the case, PSU and also a CPU cooler:
1. Lancool case PC-K58





2. Corsair CMPS-750HX PSU


3. Arctic Cooling Freezer rev. 2 CPU cooler


Installation time 3,5 hours! (yes, it wasn't a 5 min installation, because I wanted a decent wire management, which I succeeded but I want to improve it).

Confirmari reuniune restransa - clasa D informatica

Salutare din nou.
Se pare ca mai multe persoane nu mai vor sa vina la reuniunea extinsa cu tot liceul ci vor doar o reuniune mai mica, a clasei noastre.

De aceea am mai facut si pagina asta, ca sa confirmam prezenta la o astfel de reuniune.
Daca ne vom strange suficienti, vom face [si] reuniunea doar cu clasa noastra, undeva mai prin iulie, asa cum a reiesit din votul vostru.

Suficienti inseamna doar fostii elevi ai clasei, nu si insotitorii lor. Daca vor fii si din acestia, cu atat mai bine, dar deaocamdata nu sunt luati in calcul.

Ca sa nu mai caut acum linkurile, reamintesc ca locatiile paginilor de confirmari si votul cu perioada reuniunii se afla in partea dreapta jos a paginii.

Confirmari prezenta reuniune restransa - doar cu clasa D informatica:

[confirmat] Catalin Zamfir

[infirmat] deocamdata nu am suficiente informatii

Confirmarea prezentei la Reuniunea promotiei 1998

Asa cum am inceput discutia la http://locdedatcucapul.blogspot.com/2007/11/hai-sa-ne-revedem-in-2008.html, va rog sa postati in aceasta pagina, prin comentarii, faptul ca veti fii sau nu prezenti la reuniunea promotiei 1998, impreuna cu celelalte clase din liceu.

Ramane ca Dan Rada sa ne furnizeze ma multe detalii legate de organizarea evenimentului precum si suma stabilita pentru persoanele participante la reuniune UPDATE: (banuim in jur de 150RON / elev si 90RON / insotitor) - vezi comentarii si contul in RON unde vom vira aceasta suma.

Prin viramentul acestei sume in cont, fiecare persoana va confirma definitiv prezenta la eveniment. Astfel, organizatorii nu vor ramane descoperiti in eventualele cazuri in care cineva nu se prezinta. Pentru asemenea cazuri, nu va asteptati ca banii sa va fie returnati (pentru ca nu este normal si cred ca nici nu este posibil).

Va rog sa postati aici doar numele vostru si o formula de genul: "voi fii prezent / nu voi fi prezent la reuniunea promotiei 1998." - vezi nota.
Pentru alte comentarii, va rog sa folositi linkul de mai sus.

Nota: Va [re]amintesc faptul ca reuniunea va consta de fapt din cel putin 1 (un) eveniment:
1. reuniunea cu toate clasele liceului (ma rog, cele care au confirmat deja sunt A, B, C, E) la o petrecere comuna - restaurantul Rusidava

2. o reuniune mai mica, sau o intalnire a membrilor clasei D Informatica - aceasta poate fii facuta tot la un local in stilul clasic de inchiriat sau pur si simplu o iesire la bere (indiferent ca vom fii toti din clasa sau doar grupul din Bucuresti).

Asadar, in aceasta pagina veti confirma sau infirma prezenta voastra la reuniunea care va avea loc la restaurantul Rusidava, impreuna cu celelalte clase din liceu.

Pentru a doua intalnire, vom discuta ... cand ne vom vedea.

Dati mai departe, sa afle toata lumea.
tnx.

Chestionarul a expirat.

Hai sa ne revedem in 2008 !

UPDATE: Cum pagina nu mai este de actualitate, am sa o pastrez doar ca arhiva, eventual sa ne aducem aminte care eram prin clasa.

ATENTIE: Vizitati adresa http://locdedatcucapul.blogspot.com/2008/01/confirmarea-prezentei-la-reuniunea.html pentru mai multe detalii legate de reuniunea cu celelalte clase ale liceului, precum si pentru a confirma / infirma prezenta voastra la acea reuniune.

Asa dupa cum bine ati calculat (sau poate ca nu), in 2008 se fac vreo 10 anisori de cand am sarbatorit absolvirea liceului.

Haideti sa organizam o petrecere de reuniune a clasei D Informatica, sa ne mai vedem, sa mai discutam, sa mai radem, sa mai pastram legaturile, etc.

Vorbeam acum cateva zile cu Aurel ca ar fii frumos sa se intample chestiunea.
Deocamdata nu stim precis unde anume in Dragasani va fii locatia evenimentului si nici modalitatea de ... desfasurare.

Cum credeti: pastram metoda traditionala de inchiriat local/restaurant/bar si destrabalat acolo, sau pur si simplu stabilim o zi anume si un loc unde sa ne simtim bine, ca niste consumatori obisnuiti (pai trebuie sa ne sacrificam si noi macar o zi pe an) de niscaiva bauturi prin vreun bar / cafenea / pizzerie / etc ?

De aceea, va rog sa votati in formularul de pe prima pagina a blogului una sau mai multe luni cand va convine voua sa se intample fericita sindrofie.

Puteti sa detaliati alegerile facute chiar aici in aceasta pagina, cu ajutorul butoanelor de comentarii.

Sperand sa ne intalnim intr-o formatie cat mai aproape de completa... va doresc toate cele bune.

Nota: voi scrie pe baza comentariilor voastre numele persoanelor care au fost anuntate despre reuniune prin orice mijloc (mail / SMS / telefon / discutii, etc), [precum si cele care au votat luna in care se va desfasura activitatea].
