re test of L643G240, delid, liquid metal, water 18c, VID 1.152v LLC6

 

have had a quick LN2 test but no screens, took an age to figure voltages, requires very low internal volts! best mount i had cracked probably due to the hours of finding right settings, remounted several times but delta was crap 35c+ still managed upto 6.7g R15, then board had had enough, so once all sorted it should be circa 6.8g, should be able to re-test this week sometime

Great chip man!

MIne requires a lot more voltage for the same, but very same pathern in difference each 100 MHz step for vcore.

 

I wish I could do 18C water, but wife won't accept that cold indoor temp, its more like 22C ambient, when I hit 25C, I lost everything as for OC :-/

 

By the way, my highest was 5460MHz @ 25C ambient, voltage was high, too high :)

Its only an old cool box, a £20 pond pump and tap water.

Noooo man, dont tell me it :D...Because my 3rd 7700K is L643...

That second one is a damn fine chip. Any chance we see ln2 results on that?Too bad As rock will not be making a z270 mocf. By the looks of it they felt they didn't need too.

OK last two tested. The same testing setup, no delided CPUs. Ambient 22 C.

Hello there,

Picked my 7700k and Asus IX Hero Z270

Batch L643G207

Everything is auto now.

Didn't test overclock yet.

Good batch?

 

VID 1.168v

 

Possibly, use thread settings of x50 on the core, x45cache and 3600mems all auto with LLC level 5 and test lowest voltage required to run cinebenchR15 then try 52/45/3600

Thanks Nickolp and shar. I will do tests sometime hopefully this week.

I have Asus Maximus IX Hero Z270

And I honestly don't intend to delid the CPU, too risky for me and voids my warranty. I also use Noctua D15S with one fan in middle and not water.

 

1. Does VID in BIOS mean anything?

2. Should I disable XMP and reinput my RAM sticks 16-18-18-3200 1.35v manually for better OC?

3. Should I disable Asus Multicore Enhancments and switch to manual sync all cores for better control and stability?

4. Manual voltage for testing, yes? and what is a good manual value for 5GHz as a starter? 1.20v?

Thanks guys again.

And with mocf should be even lower. There are differences in voltage even between 2 Apex,one may be lower vcore and better compatibility with memory which sucks.

 

All the cpu's for sale in hwbot area are tested with mocf,imagine the surprise of someone who has M8G at home.
