After 2 months of waiting Sandy Bridge is here

Like the title says after 2 months lost with dead board and RMA related stuff finally I’ve the pleasure to play with da biatch…
Honestly, the only things that really impress me are the performances, this crap is scary fast in both of my favourite benchmarks: 3dMark 01 and Super-pi 32M.
The bad thing is that quite everything except performance isn’t exactly like I would, just to name some problems:

  • all of my Hyper kits act weird when using 2133 multiplier…and without this one the performance in 32M aren’t that good…
  • CPU quality is purely random, no need to search for specific batch, you only have to buy as much chip as you can and pray to get a good CPU.
  • BIOSes are ridiculous, laggy pages, crappy bioses that kill motherboards, poor support for certain RAMs and so on.
  • low end and low quality motherboard but premium prices.
  • etc etc…


EVGA haven’t yet showed a P67 motherboard, DFI LANparty division is dead…so I had to buy a Gigabyte.

Config:
i5-2500K # L045B311
Gigabyte P67A-UD4-B3 – bios F3B & F3
KHX & STT 2k cas8 MGH-E-Hyper
PCP&C 1200 Watt
6200 LE for 32M :: GTX 280 for 3dmark 01
WD scorpio 160 GB sata
2003 Server TW tweaked + custom CW :: XP sp3
Zerotherm Nirvana & some fans

If you are wondering why I’m using air cooling that’s because this CPU sucks monkeyballs and if using the single stage I lost at least 100 MHz.
Anyway this CPU isn’t good, even at AIR maxed out a bit under 5300 MHz.

Today a new BIOS came out, the F3, and I did a quick comparison between this and the best till now, the F3B.

F3B :: F3

super-pi 32M – 6.37.594 :: 6.37.593

3 4

3dMark 01 – 95836 :: 95750

5 6

The performances are quite the same but the new F3 is much more stable and is a bit better when using 2133 multiplier and Hyper RAMs.
Here it is, hopefully I will find a CPU good enough to break 6 min in super-pi 32M and 125K in 3dmark 01.

i7-920 @ LN2 32M fun – someone called for pwnage?

Today I and my friend Guglio had a 4 hours LN2 bench session with my good old i7-920.
After alot of pretesting with the Single Stage we managed to get a great 3rd place in the 920’s ranking on the bot.
We are really proud of it because not many days ago some guys said that I’m a fucking lamer, probably they didn’t look at HWbot or at the 32M low clock challenge on XS…

And, I’m still wondering where are all the guys with an uber CPU, seems that they are good only for CPU-Z shot.

i7-920 – SingleStage 32M testing

While all the guys around there are working on the new Sandy Bitch stuff I’m still stucking with my old bloomfield setup.
When something new come out I’m always a bit reluctant at the idea of buying without knowing everything about it, Sandy Bitch is freakin’ fast clock to clock but also have alot of downsides – just for example: no BCLKclocking, Elpida Hyper act weird with most CPU/mobo, 3dmark 01 gives strange results with everything except Gigabyte board and much more…
– Back on topic – There’s not alot to say here, I did just a really quick run that end up with an interesting result.
* the benchmark is always the same Super-PI 32M *

That’s all for now, in the near future I would like to retest this CPU at LN2, hopefully I will get good results.
On a side note: I’m just wondering where are all the guys that posted 5.5+ GHZ CPUZ shots on the Bot.
CPUZ shots are lame stuff, we are all able to test a shit load of CPUs and find the golden one but looks like that only a bunch of guys can use it to bench some real benchmarks…
