My Core 2 Duo X6800 RETAIL has arrived in my hands!!

Pull out the battery, worked for me when that happened.

I am rather concerned, as many others are I'm sure by this rather poor overclockability. Was really looking forward to getting an X6800 retail in hopes that the newer stepping would allow for much better clocking, but I guess that won't be the case. :-/ From how my 6700 did, I expected 4.2 fully stable and 4.5 benchable to be doable on simple single stage cooling...however this would require around 4.1GHz benchable on air which doesn't seem to be even close to happening.

It is very odd though...historically the highest end chips from Intel have always been a clear step ahead of the rest. (955XE vs 940, 670 vs 660, even Dothan 780 vs 770, etc) Hopefully this is only one blip on the radar. (Sorry redpriest :p:)

THANK YOU GAUTAM. You are the man, you are right, it did work.

What a quirky POS.

Yeah, lol, I really really hope I've just missed something with regards to my setup. Having to settle for less than 3.7 ghz on air is going to be tough, especially if everyone else starts blowing past me!

Dude i'd be happy OC' the 6800 i ordered to 3.2Ghz right now with a Tower120 cooler. i'm not even bothring thinking about 3.6Ghz or more :p:

Prime95 appears to be stable at 3.733ghz at 1.6v, though coretemp screams at me for temperatures past 85C. EDIT: I lied, it's not stable at that, but it's *almost*

POST at 4.0 ghz, can't get into windows at any voltage.

Now we're (you're) getting somewhere ;)

Did you changed the cooler yet ? you have a very bad temp problem..

I changed the cooler a long time ago.

Tech report couldn't get their review sample past 3.466 ghz. It's exhibiting the exact same behavior mine is, except mine is better - it will get into Windows NP at 3.733 ghz.

Maybe intel tuned down the clocking on the Step 6 chips :slapass:

0502 works with ES chip @ 1.57V air..
B2 retail supossed to scale the same if not better..

I'm really hoping that some of the experienced XS members pick up the X6800 retail stepping and show us reliably what this chip is capable of. Not to bash the current X6800 owners but I don't know how reliable your OC skills are. Give it some more time and we should see some X6800 under some more single-stage, LN2, and air.

The only reason I could think of about the bad clocks on this cpu is that he isnt just using one thread for a test of stablity.

On my T2600, I can Pi all day @ 3095 mhz, but dare I fire up any game or encode on two threads and it will reboot in less than 5 minutes.

One single pi is not a test for stablity - only two is still :)

Heres my X6800 Stepping 5 at 3.6ghz, water

Things are getting warm :slobber:

Any more details on water setup?

2 x dual heatercores
DangerDEn TDX
1/2 "
Swiftech MCP655

Used to keep my Prescott@ 4.0ghz belov 40C full load...


I had to increase the vcore to 1.48 cause dual priming gave me random reboots... But I haven`t seen prime failed the way it shuold yet...

Right now I `m priming 3.6ghz at 1.38v. Stable for 15 min so far...

Maybe It`s something wrong with mobo (Asus P5W/DH/Deluxe) causing those reboots

I might shell out some dough this weekend to upgrade my water cooling setup (I have an old Koolance that I was using for my K7 box back in the day), and see how the Conroe performs on that. It will at least tide me over until the socket 775 adapter arrives for my prometia mach 2 gt.

Prime shows 300 x 12 as your settings. can you please confirm that multis greater than 11x are enabled for you with the X6800 which i presume is a retail one? Thanks

It`s the B1 rev.

12 multi is enabled with bios 604.

Thanks... i'm after confirmation that retail X6800's have upwards of 11x unlocked on the P5W DH before i switch from 6700 to 6800.... if one of the few could confirm please ;)
I know they should, but i would like some verifiable data :)

I don't have the Asus board, but I do know my retail x6800 has multipliers unlocked above 11 up to 40 (!).

Anand's review has his Core 2 Duo X6800 reaching 4 ghz on air - unfortunately, he is also using the stepping 5 ES, so there's another data point for stepping 5 being pretty good and stepping 6 not so good. Tech-report seems to be stuck, like me, at 3.466 ghz with a voltage increase. Maybe they have a stepping 6 or maybe they have a bad stepping 5 sample, who knows?

Here with multi 14 :)

Well it's not only the badaxe that has this problem. I don't know about the overclocking yet, but the Asus P5WDH mysteriously doesn't post either and then the pull of the battery etc. brought it back a couple times, but now it won't even post after the battery removal and jumper clear, so I don't know if it's dead or not. Tonight I'll have to put the stupid celeron that I had to use to flash the bios to get the 6800 to work in the first place back in and see if the asus is alive and then re try the 6800, if it is. Something aint quite right here folks.

My P5W DH dropped dead in an odd fashion. First, it stopped being able to run CrossFire, then one of the PCI-E slots went kaput entirely, then the other one. Now it seems like it rarely posts (keyboard flash) but never displays video, regardless of CPU...have a Conroe, Presler and Celly. I hope yours doesn't suffer the same fate.

be carefull at 1.6v because 1.65 may have killed mine. It booted to a dos prompt at 1.65 (under water) temps were high 30's in the hardwrae monitor in the bios, but then I shut it down from the dos prompt, went to bed and no boot this morning. I won't know till later, but I suspect the 1.65 may have sent it over the edge even for that short a time. Unless the board is just wacked completely for some other reason.
