    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

looks like its scaling nice RBBY! Get it on LN2 for some 6.3+ action. My L311B did 5.5 cinebench on -70. so it looks almost same as yours, you can expect 6.3 2d.

 

Xtreme addict tired L315B3xx

i tried L315B5xx

 

both ok for air clocking, 1.35v 5ghz, but no scaling on ln2 with 6 to 6.1 ghz max..

 

i tried L316Bxx

others tried L317Bxx

 

all bad.

i just got my new cpu from rma my god one died after one run of SPI 1M

 

And new batch is 315B639

 

cant run SPI 32M at 4.5ghz 4cores and 1.40vcore really a turd cpu

Got few L315B371

 

Not bad air/wc, no scaling with cold though :(

 

thanks... ;-)

 

j will don't bought this

any information on L315B323?my seller only has this LOL

 

j try 313Bxx....horrible batch

 

Ny Naruto...My last 4670K was L313B373...Bech XTU @ 5.535 mhz, cb -104 and max stable frequency 5.6 ghz...

 

My new 4770K is L313B991...Yours bad ?

Has anyone tested the IMC on chips other than 4670K and 4770K? Which memory multipliers are available and how high does it go?

  • Crew

tested:

 

2x 315b407,

 

nice air clockers both 5ghz 1.35v but terrible ln2, max 6.1

 

scale list:

 

malay

310B4xx yes A

311B5xx yes A+

312B5xx yes A+

312B7xx yes A++

313Bxxx no

315Bxxx no

316Bxxx no HELL no

317Bxxx no

 

costa rica:

 

3313B4xx yes (but in splave case bad CB -80, but seems to scale, recorded 6.5cpu-z)

L313B991...terrible on SS...5 GHZ max @ 1.45V...Need to use LN2...

FROXIC has my same batch and can do 5.9 ghz WPRIME 1024 and 6.0, 6.1 3D max...

this imc seems pretty good, although a bit inflated from the impact. All air 1.65vDimm

Seems costas have strong imc's

on my 5500 1m run does it matter that i booted at 5ghz 1.45v and overclocked to 5.5ghz in windows, not sure if we are posting boot clocks or what :/

not at all man it doesnt matter, 1m stable clocks give a good indication

Fun fact,

 

nacho arrayo 4770k probly the strongest we've seen other than 8pack, batch L312B7xx.

 

here is the catch, he never tested the cpu with normal IHS. Before the 1st LN2 run nacho delid and put GELID extreme inside and replaced lid. he runs 6.5ghz for 05 and showed me screenshots

 

so now im wondering.. does delid help? because i lost some mhz if i recall correctly on my 1st chip when i did delid, but i didnt really know haswell so good back then. Who wants to try!
