i7 870 & Gigabyte P55-UD5

[Deanzo]

Hey guys,

Lots to come over the next day or two, but may as well start a thread about how I'm getting on.

Sorry, no air numbers from me for now. Just trying to see how far I can push it on sub zero cooling.

To start with, here is a shot or two of the board/setup








One with the heat sinks off.




Getting ready to go cold!



Needed to make a back plate till I can get a "real" one off Vince.




And all setup.
For the top mounting, On the far side, I used the two socket 775 holes. And on the near side the two for socket 1366.

Test Bed


i7 870
Giga P55-UD5
Team eXreme 1866 Mem
Giga GTX260 (will go cold with that later)


In this post, pay no mind at all to the times, just playing around with clocks.
And to give you a fast idea of where it is at.
No tweaks are being used, mem is crazy low etc, just trying for clocks.

CPUZ = 5512Mhz
Don't know why, but all my dump files say "corrupted" will get screenshots later.

SPI1M = 5337Mhz


wPrime 32M = 5200Mhz


3D Vantage = 5004Mhz

Nice stuff deanzo, have you tried maxing out the memory yet/testing the IMC?

What temps were you at?

[Charles Wirth]

Really nice, Im at 5.33 as well with 21x multi and cas 6

NDA is up soon and I can throw up some decent screens saved up.

[SoF]

sweet finally we see some first cold numbers from thoose chips - and they look really promising! DICE or LN2? Clockwise this is around what I was able to do with 975 on DICE so really promising considering this is the first 870 chip we see under cold at all here.

Nice start Deanzo and well i'm waiting for ln2 come in my home now hehehe

[hicookie]

Nice start Deanzo and well i'm waiting for ln2 come in my home now hehehe

very good frequency and benching, deanzo
zolkorn, wish you have fun with s1156

I can bench at 2400 Cas 10 (DDR1200) and screen close to 2500.
I had to change ram though, now on Adata.

21times cas 6...Nice.

Oh, and see you in a day or two

LN2

This out clocks both my 975 & 3570

Nice start Deanzo and well i'm waiting for ln2 come in my home now hehehe

Hey mate, thanks

Hicookie, send me a new bios!

Playing with the 750 too, decent 5+ Ghz stuff.

[hiwa]

Nice 870 Deanzo
1156 cpu's are just fun but damn slow

Nice 750 5GHz+, this one is killing all s775 Quadcores in performance

Thanks for bios bro!
btw. UD6 and UD5 same is bios ?

[hicookie]

lol, sorry , i fixed link

[MaJ0r]

Nice clock, but 2d too slow. 3d run better ))

[Deanzo]

Right then, still not my best, but starting to get the hang of it.
Not many tweaks used, really just Mhz Power.

PiFast @ 5346Mhz = 16.27sec


SPI1M @ 5363Mhz = 7.703sec


SPI32Mhz @ 5206Mhz = 7min 12sec 406mil


wPrime 32 @ 5258Mhz = 4.593sec


wPrime 1024 @ 5153Mhz = 147.437sec

Nice start Dean. See ya in Beijing (finally)

Thanks mate, and yes, it will be great to meet you at long last

very good frequency and benching, deanzo

Thanks hicookie :-)

Thanks mate, see above, not to bad.
32M is about 140Mhz behind, the others are alright though.

[MaJ0r]

Deanzo hmm, you use different voltage for each test? ) How qpi/vtt voltage?

[hey]

nice results! doesnt 870 have 23x with turbo ? i see all on 22x.

[MaJ0r]

hey in turbo mode multiplier = 24

[Vivi]

sick stuff dean, really !

see you party animals in beijjing, boarding the plane in about 8 hours

[chispy]

Great start Deanzo , great frequency and clocks.

Angelo.

Deanzo hmm, you use different voltage for each test? ) How qpi/vtt voltage?

When running 4 cores, 8 threads. More stable at the lower vcore.

As for vtt, for the most part, as much as you can give it. My setup max is 1.56.
Any more and it will not post, or if you use easytune in windows it will lock up past that.

nice results! doesnt 870 have 23x with turbo ? i see all on 22x.

Thanks.

No issues with BCLK's, so no need to play with turbo.

sick stuff dean, really !

Thanks mate, see you tomorrow

Great start Deanzo , great frequency and clocks.

Thanks brother

Hicookie,thanks for BIOS's.Probably you can post also:
For UD5 latest is F4E
For UD4 latest is F3D
For UD3 latest is F4F

[Marco André]

Can i have the latest for UD4?
