Im thinking I need to pump the vtt to 1.6ish, idk I only messed for 15 minutes

1.6 vtt at those core voltages are going to take a toll on that chip FOSHO ....... :laughing:

but you are way colder than me so maybe not.....

1.587 core 1.575 vtt killed my B batch at -30 or so was @ 5.132 Mhz validated .... and after that it never booted again ..... (tear runs down cheek)

just real quick what is the B batches?

It is a different batch just like it say's ...

No stepping changes or anything AKA C to DO

Just a differet waffer every CPU is lik an individual though they are all different .... no garentee's but my last 920 B was beast on low volts ....

I beat this beejus out of this B batch. Think I got it from splave originally?

4.83 ambient Air validation last night... but with HTT on, I can't even boot 4.7 :(

Going to try this chip on DIce once I get the gemini pot, after that I think I will have to move up to whatever is next that likes DIce :)

Bummer Splave.

This is what the seller of my incoming 920 claimed:

"Does 4.51 @ 1.37-1.38v HToff. Did 4.72 @ 1.39v HToff but wasn't stable so in order to make it stable it probably would require 1.42-1.44ish with watercooling"

Might be lies of course, but if true it may be a benchable 5 GHz chip with phase and non-wimpy voltage.

Gotta love the voltage fear out there. My 920 C0 has been at 1.41v for 18 months on water.

how can you tell if your chip is 920 B or not?

It will say it on the chip itself in the batch #. For instance:

3020A477

or

3020B477

i got this! :laughing:
3913B007
good chip right?
:club:

how low the volt is gonna go on this chip?
