Classy + D0 + H20

[Mpetrosino]

Hey guys i would like to show you my best oc so far on my Classified D0 setup. I have the CPU watercooled which keeps it around 40C idle and 65C loaded. Here are my system specs:

eVGA Classified w/nf200
Intel i7 920 D0
6gb Kingston HyperX PC3 16000 (2000mhz)
eVGA gtx 260 55nm

Here is a little screenshot, i managed to run spi 1m and beat my record to 8.70 seconds. When i tried 229bclk it just froze on me. I believe i was around 110 Pcie also. Any help OC'ing Further be greatly appreciated!

Nice temps. What is your ambient temp/cooling setup?

screenshot of the voltages pls

Ambient temps are around 75-82F. Im running an mcp 655, mcr 320, 6 high rpm yate loons on the rad, Ek Supreme w/ 1366 mounting plate. Temps dont fluctuate too much when i increase/ lower vcore.

I will get that for you in a little bit. From what i remember it was something like this:

cpu vcore : 1.5v
VDimm : 1.67v
Qpi pll : 1.3/1.35v
cpu vtt : 1.5v
There was a qpi setting i changed in bios to 4.8 gt/s
A pwm frequency in bios to 490mhz
I had uncore @ x17

[Alchemy1]

I need to redo my loop. I'm running the setup in my sig and I get temps in the low 70's @4ghz and mid 70's @4.4ghz with similar ambients, but I also run HT on.

[Mpetrosino]

how much of a difference do you get with ht off? maybe you dont have good contact with your cpu?

[Alchemy1]

I have never run any of my intel chips with HT off so I couldn't tell you the temp difference. I have remounted several times due to swapping equipment and such and the temps have stayed the same since the ambients have begun to climb.

Very nice work on that Over Clock and with Water !

Keep it up !

@Hondacity - this is what i booted @ 220bclk, then i changed voltages and qpi w/ Eleet.

QPI singal compensation to "LESS"
MCH Strap: AUTO

And you are running 2X+1 uncore speed!?

Sometimes when i set Qpi compensation to Less, i get the FF error for some reason.

2X+1? That uncore speed was more of a tester to see if something i read was actually true. But for some reason this OC only worked this one time and i cant figure out how to get it back.....Its like the PCIE is inconsistant. sometimes it will work at 107pcie and sometimes it will work at 110pcie.

@Anzial - Nice Clocks!

nice OC

@Anzial - Nice Clocks!

Right back at ya Not sure why but I did SuperPi a little faster with the same CPU/RAM clocks as you. Probably due to tigher RAM subtimings.

I did achieve that clock a couple of times but it's not easy. I have QPI compensaton set to low all the time, never had an issue with it (at least I didn't notice any). However, I seriously doubt we can make it stable under water. I mean even with my daily clock, it's already 77C under load on the hottest core, according to RealTemp (Eleet alway shows lower temps a little bit). I can imagine, ~4.8 will prolly shoot the temps with my current WC setups to 90C or more.

I see you are using stock BIOS, I think you should update it to S60Z.

I see you are using stock BIOS, I think you should update it to S60Z.

I flashed the bios about a month ago right when i got the mobo. When did S60Z come out?

*Edit* I just looked at the bios you showed me on Evga and it seems i need the 759 Version or Bios #S21S. Im going to dl and flash this bios and see how my benching goes. Keep you updated soon.

[Mpetrosino]

wow this new bios blows! Now instead of me trying to get past 222bclk i have to get past 220bclk.
