    New cpu arrived - Xeon W3570 3847A696 with unlocked cpu multiplier

    System:

    First 5hrs with cpu. Quickie tests done and I must say these W3570 3847A696 are overclocking beasts! To be able to get screenshots and validation @4911-4966Mhz HT enabled with 1.45v bios (1.440v idle) vcore is crazy!

    Temp and vcore at 4ghz (1.184v) wise, it's pretty similar to my W3520 3845A935. It's definitely cooler than my hotter W3540 3845B010 but not as cool as my i7 920 3845B260 (coolest cpu I've got).

    Room ambient = 29.0C to 30.8C

    Unlocked cpu multiplier is alot of fun

    See how far I could go for Super Pi 1M so bumped vcore from 1.45v (1.44v) to 1.4875V (1.472V) and 1.50v (1.488v). With HT still enabled managed to pull of Super Pi 1M @4911Mhz at 1.472v and cpuz validation was @5011Mhz at 1.488v but it was corrupt so next saved validation was @4997Mhz at 1.488v!

    Room ambients = ~31.4C

    Realtemp 3.42 reported around 43-47C idle temps didn't bother looking at load LOL

    Loving this W3570 3847A696 cpu even more, first time I've benched 32M Pi above 4.8Ghz with HT enabled - 4803Mhz with only 1.464v vcore ! :eek: :D Ignore the slow 32M Pi time as was using loose mem timings and low mem frequency just to see if cpu is capable of HT enabled 4.8ghz 32M Pi. Really should be down in 7min 20s range for 4.8ghz.

    Funny look at difference between 4th and 1st core temps 45C idle vs 38C idle.

    Bumped vcore up a tad for Super Pi 32M then pushed vcore up more for 3dmark05 @4803Mhz HT enabled at 1.528v. 3dmark06 cpu test would crash to desktop at 4803Mhz HT 1.528v so probably try more vcore later.

    6-9-6-22 1T Timings

    Tighten the timings on 6GB Gskill Trident 16000C9 Elpida BBSE memory even more and tried to push the W3570 to it's limits for water cooling. Did the following


    Best 32M Pi time @4821Mhz 7m 27.016s beat my 4830Mhz time at 7m 27.157s

    Thanks Jakl

    Max Xeon W3570 BCLK​

    While max bclk isn't as important on unlocked cpu multiplier Xeon W3570, still need to find out what it can do in terms of max bclk and as expected you run into a board limit way before you run into cpu limit for bclk. Managed around 226-228bclk max so far at relatively low QPI/DRAM (CPU VTT).

    System:

    3D Bench at 226bclk (225.8)
