    Evening all,

    I've got another cpu to try out today! A retail 6850 L720A 3.0ghz core 2 duo.

    Put this new toy into my current benching rig, the current results were done in 2 hours I had free tonight.

    E6850 L720A
    Asus P5k Deluxe (vcore mod)
    Cellshock C4 PC8000
    FX5500
    OCZ GameXStream 700w
    Swiftech G4 storm, Swiftech MCP650, Swiftech Triple Rad w/ 4x delta 110cfm fans

    Fired up the system and decided to shoot for highest clocks prime stable on stock volts, when I say stock I mean 1.3v set in bios not AUTO.

    I was surprised when I was able to push to 3708mhz Prime95 stable at default clocks, what surprised me even more was being prime stable at 3900mhz with only a jump to 1.375v!

    Raising volts higher gave me 4000mhz prime stable at 1.425v quite a reasonable achievement for the 6850, I think the only thing that might hold this CPU back is the 9x multiplier!

    I always like to determine my max FSB early, on water it was 516mhz prime 95 stable and 520mhz benchable, so 520mhz would give me a theoretical maximum of 4680mhz! Damn I hope cold gives me more fsb, like 60mhz more fsb ;) You would think at least 540mhz fsb under appropriate cooling...

    520mhz fsb validation

    Max validation, well this was interesting, max validation was 4302mhz on water, it was done at 1.6v, above 1.6v max validation actually went down, very close to 4304mhz was achievable at 1.5v also. 478 * 9 = 4302mhz

    4302mhz validation

    This chip runs VERY cool, I had a thermal probe mounted on top of the CPU and it rarely got past 30 degrees even under prime95 load at 4ghz, this places the CPU temperature not over 43 degrees celcius. Most of the time CORETEMP read about 10degrees idle, ranging up to 17degrees when 1.6v was used.

    Hopefully this is the start of something beautiful! Should have some DICE for this CPU in the coming weeks, alot more work to be done to push these boundaries even further first though.

    Phoar! Awesome! I've been dying to see how the retail e6850s run and by the looks of things they don't disappoint. Hmmm so tempted to get one but do I really need it :confused: :rolleyes:

    Excellent work indeed. I have had my eye on one of these, I think this seals it for me.:thumbup:

    yeah the chips seem good, we shall see soon if dice really unlock the FSB on these chips..

    516FSB ain't bad... if you want to try DDR3 with micron ICs you'd need a cpu with very high FSB to hit > DDR3-2000 as the highest divider you'd have is 1:2 so need >500FSB on your cpu

    I have the E6850 also.

    Without barely trying i'm currently running it at 3.6GHz on stock voltage with ddr2667@800MHz

    Very easy to get free MHz out of this one, and that's coming from someone who's never been very successful with overclocking.

    Cheers

    thanks guys,

    yeah these chips are excellent, the way they scale under cold on low temperatures are quite incredible...

    look forward to seeing all your results guys!
