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.

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 ...

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

benchable at 5.7-5.8 max with 1.85v + ..
