sabishiihito Posted September 7, 2017 Share Posted September 7, 2017 Binning some of my B-die on M9A, 4133C12 seems impossible so I just aimed for 4000 12-11-11 tight subs. TridentZ 4133 Pretty low volts, these might have the best shot at 4133. Dominator Torque 3200C14 Disappointing. 2.00v for 4000C12 is not impressive at all.

speed.fastest Posted September 9, 2017 Share Posted September 9, 2017 @sabishiihito : Actually my 3466 C16 kit above did 4K C12 at 2v, but it scale up to 2.05v with latest BIOS with waza. My tips for B-Die binning is find the right VTTDDR (usually around 0.925-0.9875v, many kit just 0.925v or 0.95v). When you already have the right VTTDDR (Testing it with SuperPi 32m Waza), you can push DRAM Voltage as much as the mem still scaling. My 3466 topped out at 2.05v. Always testing it with 32m Waza if you want to know the right voltage first Quote Link to comment Share on other sites More sharing options...
suzuki Posted September 9, 2017 Share Posted September 9, 2017 How do you know that you have the right vttddr? Sent from my iPhone using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
speed.fastest Posted September 9, 2017 Share Posted September 9, 2017 Testing it at superpi 32m waza, you can try 4000 12-11-11 first, then try what can it do at 12-12-12, put more dram voltage, try more or less vttddr, until you when you increase dram voltage or vttddr it causing unstable.

suzuki Posted September 9, 2017 Share Posted September 9, 2017 I mean how you figure out which is the perfect vttddr for your kit? For example if spi 32m works with 0.925/0.95/0.987 v the same way,with no errors,which one is the good one ? Or at a certain point one or two of them they will throw your ram unstable ?

speed.fastest Posted September 9, 2017 Share Posted September 9, 2017 (edited) if you push above your current limit, try which vtt is better. It will show more stability. If until 0.9875v it still scale push more, until you see negative scaling, usually more vtt more stable and you can push more mhz until negative scaling. //edit Forgot to add something, default vtt is half of vdram, sometimes people just set vdram from BIOS and push more vdram it causing unstability, maybe its not vdram limit just vttddr limit, and some memory need more vttddr then vdram.

How you test the imc on your cpu ? How can you find out if that one is the limit and not the ram kit ?

Sparks.nl Posted September 29, 2017 Share Posted September 29, 2017 The only way I have at this point is that I tested a kit at higher speeds on a different cpu. Quote Link to comment Share on other sites More sharing options...

Castle Posted October 1, 2017 Share Posted October 1, 2017 Tested 4266 rgb,failed to train 4000 12 12 12 1.85-2V. Also latest 4266 were worser on tight timings compared to 3600c16. Latest 3733 c17 and 3600c15 again were worser,1707 serial week,1701 on pcb,644 week on IC. On the average from 5 sets of 3600C16 i had way better average than on 7 sets of 4266.Not to mention that 4266 i had 3 kits with one module DOA. It is what it is , i binned over 100 kits overall and i have 3 modules super good,found about 6 GOOD(4133 12 11 11 Spi 32M wazza) and about 10 4000-4040 which is in my book average. My advice would be to get a few kits of 3600 17-18-18 or 16 16 16 NON-RGB and keep the best,return the rest. Sorry to be the deal-breaker for the RGB but the different PCB makes handling a bunny, for instance lots of 55 codes at reboot or cold-startup at the same time when they were memtest-stable,this is PCB to blaim,might be additional noise caused by the leds or motherboards that are not perfect tuned for this. I stated my own experience , you can believe me or not,this is opinion based as i said 100 kits of b-die G.skill retail tested,completely waste of cash ,time and resources . While you might see other "retail" kits 4200+ superpi stable, you know unicorns do not exist and real-life experience is so harsh I have been reading all your guides on DDR4 memory overclocking and I have the Trident Z 3600 C17 Kit and an Apex motherboard. I am trying to overclock to 4133mhz C12 and am getting the qcode 49, which stays on there for about 5-10 seconds and then it changes qcode 2b and then stays at that code until I either power off the board or press the safe mode button. Could you please tell me what those codes mean as they are not in the Apex manual and what would I need to adjust in my memory timings to overcome those two codes and get it to boot up? Thanks. 1 Quote Link to comment Share on other sites More sharing options...

speed.fastest Posted October 2, 2017 Share Posted October 2, 2017 What if you’re limited to ambient cooling? On Z270 Apex it will mazed around 4080-4140 32m waza on air, on X299 Apex with Kaby Lake X you will have more if not limited by memory.

Castle Posted October 2, 2017 Share Posted October 2, 2017 On the Z270 Apex, when trying to overclock to 4133 C12, what does it mean when it gets a qcode of 49 for about 5-10 seconds, followed by a qcode of 2b and then it stays on 2b until you reset the board or use the safe button?

Castle Posted October 3, 2017 Share Posted October 3, 2017 When overclocking b-die memory on an Asus Z270 Apex board with tight timings of 12-11-11-28-220-1T at speeds of either 4000 or 4133mhz, what does it mean when upon memory training and boot up, it gets a code of 49 followed by a code of 2b on the LED display on the board? Is it a problem with timings, or RTL/IOLS or voltages ? Quote Link to comment Share on other sites More sharing options...
Alex@ro Posted October 3, 2017 Share Posted October 3, 2017 Wrong subtimings or.mems need more volts or less volts or they can't handle that speed.... Try 3866 profile fredyama profile, does it work?

Sent from my SM-G935F using Tapatalk Yes Fredyama's 3866 profile does work, the only change I had to make was setting IO and SA voltage both from AUTO to 1.25 volts. Dram voltage is at 1.90 volts which is what the profile sets it to. All the timings in the 3866 profile worked perfectly. But what does that mean in relation to trying to get 4133 C12 to work ? I have read all your DDR4 guides that you have written, which has helped me learn how to overclock b-die, but the codes 49 and 2b are not covered in your guides as to what they could be referring to and what to change, which is why I am not sure what to fix in order for it to work successfully at 4133.

sabishiihito Posted October 4, 2017 Share Posted October 4, 2017 I get 49 on weak sticks. If you’re seeing that, 99.9% chance the simply aren’t going to run at those settings. My best advice would be to increase CR to 2. Quote Link to comment Share on other sites More sharing options...
