i7 860 - eVGA P55 FTW

[Chr0n1c]

Just set this rig up last night, very happy with it thus far.

i7 860
4GB Corsair Dominator GT 1600Mhz C7
eVGA P55 FTW
GTX 280 @ 700/1220 (will change out to 5870 next month)
TorqX SSD
Corsair TX850 psu
Vista 64



And it clocks very well, and easily. 4.2Ghz was the first OC i tried on a cheap CM Hyper TX3 air cooler and it was running 3DM Vantage and Cinebench. (took 1.35v on the chip) I won't be testing for long term stability until I get better cooling setup.

One question I do have though is what is a safe VTT? I wasn't too sure so I had used 1.4v but whats safe for 24/7?

Cool. Do u experience power recycling issue as everytime u switch on the comp, the CPU will spin , then it will power off then power on again

[Chr0n1c]

I have yes. Not sure why this is but it hasn't been a stability issue. Only happens when I power up.

Is there some underlying issue with the board I am not aware of?

Thx

[Chr0n1c]

I haven't found anything besides one post on the eVGA forums and that user says it is normal for it to "boot twice" ???

Strange.

[RADCOM]

Coolio, nice initial results. I have similar kit but I haven't put it together yet, looking at yours I'm afraid the waterblock I've got for the P55 won't fit What batch number is your Ci7 860? mine is L926B436 packed 08/05/09,shall we make an Official thread

[Chr0n1c]

Shamino told me this below in regards to the "power cycling" it is actually....

this is is clockgen to switch modes, and part of normal bios operation on this mobo so dont worry

Radcom, I'm not near my retail box atm but when I get home I will message you the batch. A thread sounds good ^^

Which block did you buy?

Hi Thar! I happen to have the same RAM modules, only running them in a "normal" Asus P7P55D board. Do you have any luck at overclocking the modules? Mine have a really hard time running even at 1600mhz with 7-7-7-20 timings (1.65v DRAM / 1.15v IMC).. Also my XMP profile for the sticks reads 8-7-7-20, same with you?

I'm currently running them at 1750mhz 8-8-8-24 at the "stock" voltages as posted before, this seems to be the max for these timings/voltages. Still a bit dissapointed..

Anyway very nice setup you got there

Running some blend tonight on this new rig. I'm so glad people are starting to post results with this board and cpu. I will have to get this chip on water to blend any higher.

[namegt]

Oh ~ ATI 5870 ~
It is a great score and a card.

Gallery of the system that you want to see.

Thank you.
Very nice results with your oc's . You were able to keep turbo enabled with your testing? I had it disabled, will have to try that.

Abit P35 had that dualboot thing it's quite annoying really. I managed to get it to 4Ghz but it's unstable I'm using the Xigmatek S1283 on the 775 holes but it didn't seem to fit quite well. I have a heatkiller LC but that too is the 775 version, I will get the 1156, this dual hole thing isn't working for me
NameGt you are owning that board and chip lol how are you getting "22" multiplier?

Impressive mate

Impressive mate

Thank you Sergio.

[OC Nub]

Testing blend at 4000mhz with speedstep enabled to use the 22 multi.

[Chrono Detector]

Whats the required voltage to get to 4Ghz stable? I just bought the 860 myself and I'm waiting for my motherboard to arrive. I'll be using a Gigabyte GA-P55-UD5.

[OC Nub]

So far I have needed 1.39vcore bios, 1.40vtt but am still testing. This board has amazingly low vdrop, what you set in bios is what you get idle in cpuz. Vdroop under load is just as impressive. I cant see any need for using LLC/Without VDroop option. The only complaint I would have are the larger gaps between VTT setting compared to what i am use to on the Giga boards. So far I think this is an awesome board. Time will tell I guess.

Pic of current setup, just switched out fans to try and lower temps. Added 2x Scythe 133cfm to the True and so far I see 5c lower in blend at 4.0ghz.
Edit: Grr now only 3c less. Need to put on water but hate to take my Giga rig apart.

[Chr0n1c]

Hell ya nice results everyone!

For the gentleman that asked my batch is L927B320

I am LinX stable @ 4Ghz 1.3V

I'm gonna test for more now for benching, and more tomorrow under water.

[OC Nub]

End result seems to be 2c less on the hottest core with push/pull config vs single fan.

[axffox]

love this processor and mobo!


First Oc i did,


4.2 GHz results
http://valid.canardpc.com/show_oc.php?id=724478


Core i7 920 @ 4 GHz (191x21) + GTX 275 (stock clocks)

Core i7 860 @ 4 GHz (191x21) + GTX 275 (stock clocks)

[OC Nub]

Very nice axffox.
When running blend at over 4ghz somewhere around 2hours of blend I lose video. No bsod, no freezing but video is lost, doesn't reboot or seem to be the normal freeze. Cannot get video back so have to hit the restart button or power off. I don't get the normal screen on boot when overclock fails it reboots fine. I am guessing this has to do with the on die pci-e. Anyone else experience this?

[RADCOM]

My cpu ( ci7 860 ) only goes to about 3.3Ghz on the dummy overclock and then it fails OCCT. I've remounted the stock cooler several times but the chip is still hot as hell. I know it depends a little bit on luck but most people seem to be able to get 4.0Ghz stable on the stock cooler, Is this a bad chip or am I missing something?

[OC Nub]

I haven't seen anyone stable in blend on stock cooler at 4ghz. I have seen people say stable but then post a validation, super pi or 06 run. From what I have seen 3.6ghz is about tops for stock hs. Also the auto or dummy oc adds more voltage then may be required. Best to set voltages manually, this will lower temps.

Cheers I was getting a bit concerned, When we start the "Official post your overclocks tipz and trickz thread" we'll ask for some stability verification The chip will be going under water soon hopefully she'll beehive then.

[Chr0n1c]

Yea the dummy oc does add more voltage than needed which in turn adds a ton of heat. Also the stock cooler is a complete joke.
I've been doing several hours of use @ 4Ghz with no problem on my end, also a few hours under LinX. I am very very pleased.

I was going to get watercooling today but I didn't like the kit at the local shop so I am going to build my own. I can run SPi 1M on all four cores @ 4.45Ghz 1.4V but thats about it. I am hoping that once I get all my cooling crap in order I'll be at atleast 4.3Ghz stable for daily use.

Working on putting the system in my CM HAF 932 atm.
