2 x L421B985

1.32v 5ghz 32m = 6.2 1m and 6.5 validate. -105. 1.7v. Im sure if it was -130 cb we would see nicer results.

 

2nd cpu

 

1.42v 5ghz 32m. No ln2 left for this one.

 

Serial for good one is 3669 and worse one 3929. Ill try buy lower serials tomorrow. But im happy about the batch

test made on watercooling,with 20 degrees ambient.

 

don't mind the efficiency,it was a short test,plug and play

 

4790k L425B370 A2127

4790k L425B405 A1127

4690K L420B903 A2183

4690K L421C035 A1204

4690K L421C035 A0431

neither of those CPUs load OS with 4c/4t at 5000MHz (Tried until 1.4V)

I have already tested around 30 retails 4790K, best was 1.35 GHz 4/8 5 GHz air... I don't have luck DC

wow suzuki. 5.3 lol SICK

Don´t kill the cpu, suzuki

5.3 @1.46 v spi32m stable with temperatures up to 55 degrees max...impossible for it to die like this .

I have some stability issues,i am still learning this architecture.

Can it be 24/7 stable at 5g?

Wow nice chip suzuki!

Did you buy that CPU as rejected? I mean this CPU doesn't scale on cold or has extremelly low cb and seems it was delided, am I right?

It was never tested on cold,nor delidded. I will test it soon on dice.

Will be interesting to see what CPU can do )

5 x L421B985 - great air batch, first cpu CB is -105, will see if that was unlucky or batch related

 

serial number:

 

A3959 - 5ghz 32m 1.4v

A3820 - 5ghz 32m 1.32v

A3669 - 5ghz 32m 1.3v

A3629 - 5ghz 32m 1.34v

A3559 - 5ghz 32m 1.37v

 

sweetspot of serials is in 3700 - 3800 range

Do you test with 4/8 and win7 or XP and cores/HT disabled?

i test 4c 4t windows XP.

 

4c 8t win7 is too harsh on devils canyon .

 

the best one runs 1.35v 4.9ghz XTU stress test stable 24/7 - win7 all cores

the others do 1.35v 4.8ghz XTU stress test stable

 

so they are wall'ing in weird places, they are ALOT better than 4770k at multi thread on air/water. you will need epic gem 4770k for 4.9ghz 24/7

Devils canyon might be a bit of a flop at the moment in terms of extreme overclocking, but the Penitums are just god awful

 

There has only been what, two or three good batches so far??

 

On a side note, Vivi, update the first post

Pentium G3258 - L417C016# stable through R15/R11.5/XTU @ below

 

6017ghz @ -116c, 1.648vcore / 2.4vin : IMC tested to 5.7ghz, 2850 c9 tight

EDIT

 

i didnt test the chips properly,

 

L421B985 - A3824 is 1.25v 5ghz 4c 4t 32m XP. Win7 needs alooot more v, dont understand these chips

L421B985 - A3624 is 1.27v 5ghz 4c 4t 32m XP.

L421B985 - A3555 is 1.35v 5ghhz 4c 4t 32m XP

 

LN2 tonight on best 2

Aaaaand?

1.25v cpu did 6.4ghz 1m at -138 (totally mental CB)

1.27v cpu did 6.3ghz 1m at -130

1.35v cpu didnt test cause dont care

Verry nice

1.25v cpu did 6.4ghz 1m at -138 (totally mental CB)

1.27v cpu did 6.3ghz 1m at -130

1.35v cpu didnt test cause dont care

 

Thanks for the info. Still seems like 4790k doesn't work like it should on ln2. Maybe Intel tuned it for air/water in some way...

 

I was able to hit 5.0 a few days ago. Made me VERY happy !!!!

 

My 4790K batch number is: L419B559

 

 

OK GUYS!
