Xeon W3570 3847A696 @4997Mhz HT H20 !

[eva2000]

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

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).

System:

• Intel Xeon W3570 3847A696
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• Gskill Trident F3-16000CL9T-6GBTD
• 512MB Inno3D 8800GT OC Edition 190.62WHQL
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• Dual Boot - WinXP Pro SP3 (nLite fully updated) with Vista Theme & Win7 Ultimate 64bit RTM

Room ambient = 29.0C to 30.8C

Unlocked cpu multiplier is alot of fun

Next day benching, trying to see how 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

that. is. nuts.

 

[dajeepster]

i was going to ask what case, but then i saw that you didn't use one

 

[myocardia]

Room ambients = ~31.4C

You need to invest in an air conditioner, not computer equipment. BTW, no offense meant, but that's well above the human sweating threshold.

 

[zagood]

great, now I've got to get someone to switch out my drool cup.

 

[eva2000]

thanks guys... yeah cpu is a monster overclocker!!

Room temps are normal around this time of year in Australia can get as high as 36C room temps as we're in heatwave like season.. some states are hitting 38-41C outdoor temps this past week!

 

[wwswimming]

very impressive.

i wonder what's the highest OC on a dual-socket-1366 system.

check out this beaut

SUPERMICRO MBD-X8DAH+-O Dual LGA 1366

 

[eva2000]

Not sure you'd be able to clock much as dual socket 1366 don't have much to offer in bios for oc'ing options/voltages unless you grab Asus equivalents.

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 ! 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.

rofl eva... u finally come back after our move from VB?

Well welcome back super lurker.

[Ayah]

Damn. That chip is a superstar. It deserves a trophy case.

 

[deputc26]

Wow that is insane, validation at 5Ghz with an i7 on H2O is truly nuts.

thanks guys.. lol at photo Eddie hehe

yeah switch to vB means I'll be around here more

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

• HT on - 21x200bclk - 2000mhz 6-9-6-22 1T at 1.74v
• HT on - 22x200bclk - 2000mhz 6-9-6-22 1T at 1.74v
• HT on - 23x200bclk - 2000mhz 6-9-6-22 1T at 1.74v
• HT off - 24x201bclk - 2008mhz 6-9-6-22 1T at 1.78v <-- tried HT on and off but 24x202 errored out in 32M Pi, so limit on H20 might be 4830mhz HT

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

Max Validation @2050Mhz 6-9-6-22 1T at 1.78v​

For the price of that processor alone it better do my dishes too


Nice overclock!

 

[aigomorla]

the W3570 is a monster clocker.

So are the W3580's. :T

Also a W3520 if you have the right bios to unlock it.

Nice overclock!

W3570 above from ebay = US$595 + shipping US$45

the W3570 is a monster clocker.

Also a W3520 if you have the right bios to unlock it.

Yeah my W3520 3845A935 on DFI UT X58-T3H8 on H20 did 4877mhz max validation with HT off heh. But this W3570 is a monster for sure

 

[n7]

Nice!

Also nice to see you posting on AT.

I'm used to seeing your great results & memory insight on XS/OCN, so definitely great to see you here now too :sneaky:

 

[eva2000]

thanks n7... glad to finally be more active here

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:

• Intel Xeon W3570 3847A696
