    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

Agree there, my good one is 1.008v but from what i've seen Lewis it may not be a hard and fast rule.

Batch # 3332B372 - 4.7Ghz @ 1.375v - stock vcore - 1.023v

Batch # 3333C396 - 4.6Ghz @ 1.375v - stock vcore - 1.053v

Batch # L310B507 - not here yet hope it's good

Finally got myself some Haswell.

 

First CPU looks good, or at least above average. Will have to see under LN2 if it scales :D

Coldbug was bad; around -95.

 

Multimeter voltage was around 1.79v

 

Edit: Thermometer might have been inaccurate by 10 degrees so coldbug was possibly -105

Hi eyeryone I just wanted to give some quick info on batch #L347B894 Malay which arrived today.

 

UEFI screen everything on AUTO

Will see what it can do on my H100 but don´t expect too much i´m not into hardcore OC.

 

greetz :)

4670k

L350B801

 

1.044vid

1.4v 5ghz no go

 

Looks like things are just going downhill with the newer batches :(

Has anyone i5 4670K with this batch?:

 

3329B715 Costa Rica?

 

I need OC settings.

 

Now i don't set the ring voltage&frequency just the cpu voltage and freq.

 

Under x264 64bit hd encoding stabile 4,4 GHz@ 1,288V :S

Bios Settings:

Adjust Cpu Ratio: 44

Adjust Cpu voltage 1,272V

Offset:Auto/Auto

 

Ring ratio/voltage/offset-all on auto.

DigitAll: all on auto.

 

Is it good or s.h.i.t. ?

 

Now i use adaptive settings not override.

try playing about with the cache ration too, set that to x40 and see if you are stable at lower voltage then. At the moment it's not looking that good a chip I'm afraid :(

I tried, i got the same results.

 

I tried at 4,5Ghz, x264 HD Bencmark 5.0.1 need 1,344V :(

 

@4,6GHz- 1,4V frozen under windows 7 startup ...

If i give more than 1,4V always frozen my computer.

 

affect the power supply or the motherboard?

BeQuiet System Power 7 400W PSU/ MSI Z87 G43 mobo.

I know its not the best for oc.

I had about 3x L315B407, good air clockers but did not scale on LN2 for me, lets hope yours is different!

 

Mine did 1.36v 5ghz 32m for your reference, and was a very hot chip, 87c load average at 1.4v on corsair h60 and 4.5ghz cinebench

 

L315B407 looks good so far. All did 4,5 - 4,6 on air Primestable and stay below 80°C

 

Need to test on LN2 tho

 

Hello there, I have the same batch as this one and it requires 1.265VID for 4,4 on prime and it doesn't boot with 4,6 1.25VID. I could be doing something wrong since many from this batch have done much better than me. Can you please share the settings you used to run those speeds. I know this is a really old post but i'm kinda puzzled at this result and thinking it could be my Mobo(Asus Hero). Feedback is much appreciated.

 

Additional info: Auto Uncore multi and Vring, 1.87 Vin, LLC lvl 8 (SVID off, Igpu off, Cstates enabled w/ c7 short). H100i cooler
