Mobo - Asrock Z170M OC Formula

Mem - G.Skill 2x 8GB 3600C16 at XMP settings

 

Batch No - L639F976.

 

52/49/3600 - 1.32v Cinebench R15 - PASS

 

53/49/3600 - 1.38v Cinebench R15 - PASS

 

 

Plz add 50/45/3600 CB R15 plz... what a nice CPU you got there... which cooling ?

Mobo used to test:

ASUS STRIX Z270G R.O.G.

 

Cooling:

EKWB Supreme HF Nickel Full Cu, custom watercooling - not overkill...

 

L643G337

VID: 1.152

Not delidded

5000/4500/3600 1.235V BIOS (cpu-z @ 1.226V)

 

ASUS has a LOT of work with Z270G STRIX, either that or this CPU is odd.... My SA is set to 1.3V to boot with 3466 on A1+B1, A2+B2 = 3600 same settings, but higher is not happening, and it won't boot most of the time..

 

CPU does

5200/4900/xxxx @ 1.39v

5100(4900, AVX offset)/4500/3200 @ 1.31V P95 8-8 ~ 89 to 93C

I think this chip deserves a delid :)

 

And I got lucky in the ram-draw as well... It IS the mobo, likely the BIOS, that is holding me back

 

Ram @ 3400 16-16-16-36

3466 is max stable for booting, higher it wont boot most of the time..

This it can do at 11-11-11....

3200 10-10-10, fairly acceptable voltage, higher wont allow 1T on the mobo..

A tiny bit of pure madness, 9-9-9 and unacceptable high voltage...

My CPU, L639F Batch, vid 1.168v (On Asus), not delidded, try to find max clock that i can validate to CPU-Z. Vcore 1.475v (LLC Lv6, stable at 1.475v). Cooler Custom Water 3x120 Ambient about 26-28 Celcius.

5546 MHz 4C/8T

 

This CPU did 5.3/4.9 3DMark05 not delidded yet, same ambient temp & cooler :D

To add to this I figured out the average voltage needed based upon the binning criteria, as well as the median V. There were 35 total entries 3 of which have no info, so 32 counted

 

Total = 41.635v

 

41.635 / 32 = 1.30109375v Average

High- 1.375v Low- 1.230v Median- 1.3025v

Full disclosure: CPUs were provided by Intel, coming straight from the production line. I didn't see any spectacular clocks at the World Tour event, so I'm guessing whoever buys retail now will have more luck than us :D

7700K L640F773 with Impact+H110i

 

5.0/4.5GHz 32M needs 1.38V 2c2t

5.0/5.0GHz 32M doesn't pass up tp 1.45V

4.5/4.0GHz R15 needs 1.21V

5.0/4.5GHz R15 doesn't pass up to 1.45V

1600MHz mem needs 1.10V SA for memtest

1800MHz mem needs 1.35-1.40V SA for memtest

1866MHz mem won't pass 32M with any SA

That means my issue with around 1.3V SA to get 1733 might be the chip?? Despite it does really low timings pretty darn close to that frequency??

 

If so, anything wrong in using lets say 1.4-1.5V SA - and indeed thinking daily, I cannot accept that the chip won't do 2000MHz ram.

Don't fully agree with you, but I do think the more information the better.

 

Hope #0 can be edited to a list of information 'required'

Or a new thread starting with spreadsheet of information gathered in this thread, and with instructions how to test - in order to get valid data that can be added to the spreadsheet.

 

Meanwhile, I will stay in my corner and be grumpy why we don't do XTU benchmark instead, it sure needs higher vcore to pass, CB15 is way too light.. Hope stores that pre-bin CPUs actually use P95 8-8 AVX (The Leeghoofd test!) and not CB15, would suck to buy a chip thinking its stable and then it turns out to be CB15 :(

But as for XTU or harder benches/tests, all the binners used CB15, so, it makes sense to stick with that test...

 

I can get 51 stable with 2 AVX offset (working on getting it to 1) before the delid - as for the 8-8 test, and that hits very close to 100C which is instant freeze

60mV on vcore?

Well, while it has impact on VID, it does not affect finding lowest vcore for the test? Personally I used lowest vcore at LLC 7 on ASUS while testing my chip, board is listed in my post too anyway.

Ofc it does. 1.25v on mocf could be 1.3v on hero making any r15 @1.25v 1.35v etc irrelevant without posting which board. In the real world that could be the difference between 5.2 chip and a 5.3 chip on ambient.

 

Not just for batch thread info, but for sellers / buyers of used chips I'd say that's quite important to know.

 

For example, I've got a chip here that's .050v difference between mocf and asus around 1.3v.
