Testing criteria

 

5000mhz core, 4500mhz cache, 3600mhz mems (if possible), test for lowest vcore for Cinebench R15!

 

For scaling testing:

 

Increase core by 1 multi to check scaling and post your results (with a screenshot)

 

 

List proper batch nr, the CPU VID, the Vcore needed for 5GHz, CPU delidded yes or no, the Mobo type and used cooling

 

See post #56 for my results

 

Here's the current HWBOT listing:

Picked a 7700K up today and had a quick play.

Batch L639(retail), MOCF(7.21b), watercooled, delid

 

Cine R15

 

50/42/3000 everything auto, lowest pass 1.205v

 

53/50/4080c12 1.465v

 

wow sounds like really nice chip

Not seen much info apart from the odd FB post and of course the subs here, so it would be nice to see others findings and not just the end result.

Yeah likewise, well wont be taking it cold until the apex. Been 11 months for me so i can wait a little longer!

You should set up a voltage point for everyone to test,like 1.35v cinebench,for exeample.

5 ghz it's not relevant anymore as most of them do that,but how the scalling is up to 1.35v is relevant to any air/watercooler .

I heard of o few "specimens" that do prime 95 at 5.3 ghz@1.35v ,maybe in the next month other monster cpu's will be unveilled .

One I bought 2 days ago think it's L641 batch will check when home, not delid 50/45 will delid soon and try cold

 

Room temps prob 28c

That's impossible with my CPU without deliding. Hitting the limit at < 1.3V on AIO and 23C room temperature.

Can't do much more than 5.1 on AIO, because of temperature.

 

5G@1.2V

Some of them scale better than others,it will not be so relevant if you test only 5 ghz.

At least do 5 & 5.1 ghz ,to see diference in the voltage and scaling potential.

Raise uncore to 4500 and see if it still passes...

 

In fact 5GHz is a good comparison point regarding temps... From the ones (35 pieces) we tested last week, the best that could do multiple runs of CB R15 (5000/4500 & mems at 3600) with a non fixated DH 15 was at 1.23Vcore on GB Z270X SOC. (Non delidded)

 

Average voltage was around 1.285Vcore

 

Massman has the Excel sheet

I can do multiple passes at 5.

Raising uncore to 4.8 needs bump in voltage to 1.23V.

Then for 5.1 cores, it needs around 1.28V.

VID is 1.104 on Asrock OCF.

 

I will test on LN2 and don't see a point pushing hard on air/AIO for 5.2 - 5.3 with temps hitting well above 90.

Cache seems typical to Skylake or even worse,among the cpu's i tested for 5000 cache lowest ones were with 1.30-1.31,4800 worked ok for 1.23-4 tough. Best cpu ever i touched would not crush when set 5000/5000 1.27,for complete stabilty in 32M and stuff would be 1.285V for 5000 cache :)

Sorry for barking here.

 

Anyone made a spreadsheet of batch / volt etc...?

 

Just got myself a L643, not tested yet.

Ok should we keep in line then hwbotters?? Start at 50/45/36 and raise core to check scaling??

I'll have a go later and post.

Being a dick, can I suggest one more thing added? Ram modules and size.

 

Personally I will try to see if 2x 8GB vs. 2x 16GB(sorry wasnt 2*32, lol) makes any difference to how much uncore and ram it will allow at each vgpu

 

Finally: VID, default, I think it was Splave whom listed that on facebook, I somehow find that interesting too...

 

If nobody else reports in, I could start a spreadsheet... Think it would make more sense Massman doing it, if he already has 35 chips listed.

 

Will test my chip tomorrow, I became uncle a few hours ago, hence why not test the chip yet^^

Not many have 2 x 32GB... don't see any purpose need in that, most bench with B-Die anyway...

 

Keep it simple and straightforward; something everybody can test or replicate...

 

I'll keep the excell updated once I get it

Your the man!

Oh and I meant 2x 16GB, I will test both, just for the fun of it, have 2 kits at home, and 3rd waiting pickup.

 

F4-3400C16D-32GTZ

235 Euro for 32GB D4-3400, I couldnt resist temptation.

 

B-Die is true as for benching at the moment.

What do you think of the VID part? Worth putting there or not^^
