L311B512 1.41V 5GHZ. ln2 6.05 cinebench 6.3, 2D (-120)

 

seems need to find scaling batch too, not just good volt

 

 

HI ViVi,

 

Noted thanks

  • Just for integritiy L311B515 4770k

  • Batch L310B487 seems very good...5.1 GHZ PI 1MB benchable at 1.284V 4C/8T air cooled...

    Officially I surrender. My good looking Haswell died during testing CB on low volts (1.5v), going from -80*C to -105*C. I got BSOD and that's all.   It was QEH6 ES reviewer sample. 1.275v 4/8 @ 5 G

CB?

Haven't got the chance yet to do it. When I do, I'll let you know. I have to for the 06 dual gpu cup anyways.

thanks man :)

 

this chip got a real good imc i think, 4.7gig easy boot with 1.3v vring, not bench stable though.. 4600/4600 / 2400 c6 1.24v/1.3v/1.88v is superpi 4m stable.

 

tomorrow further memory testing then hopefully ln2 sessions on friday and saturday. it feels like a good chip to me.

 

L251A899 very early batch ..

nearly forgot this,with updated X01 bios and properly working oc buttons on the z87x-oc board. 5.1gig valid almost succeed,but not, soo 5gig is possible with lower voltage.

On my 4670K I could do 5.1Ghz 1m un on air. Max tho, barely made it with the M6E and slowmode for saving it. 5GHz shouldn't be a problem.

benching this shit right now

6.2 valid 1.87v

5.8 32m barely with 1.87v -115c cb awwwyeah

Mine did 5.8 1M on -70°C dice... I hope it doesn't have a terrible CB :/

 

(L310B492)

 

well my cpu had a quite good delta between the thermometer readout and realtemp monitoring ( 20C delta ) so this -115c -120c coldbug is about -95-100C coldbug on the cores or the vrm, LOL

 

it hurts ...

back down on the volts.. ES I had did 6000 wprime 1024 with 1.65V

 

ES in general don't need that much vcore

 

this one needs it.

6000mhz validation requires 1.79v ..

L310B491 is a not bad batch to look for. It scales with cold and handpicking on AC seems to be the write method for this batch.

 

5 GHz 4/8 @ 1.35v @ 6.7 GHz CPU-Z one core, 1 core boot 6.5 GHz @ 1.9v to OS, can't run spi 32M

 

5 GHz 4/8 @ 1.275v @ CPU-Z not tested though, but boots 6.5 GHz 4 core @ 1.8v and enters OS and runs SPI 32M

 

from this batch cpu which can't do 5 GHz 4/8 air is a very bad one on LN2 ;)

 

Have fun!

 

BTW

 

But this batch is fragile so be gentle with those cpus :D

L314B506

 

air (deepcool frostwin)

Cpu voltage 1.26,

frequency - 4.7 GHz (4/8),

ring freq - 4GHz,

ring voltage -1.035,

vccsa - 0.92.
