October 18, 20159 yr I haven't yet seen any Samsung-based Kingston DDR4. Samsung has always been a rare sight on Kingston for business reasons so it's highly unlikely that we will get retail E-die HyperX.
October 18, 20159 yr Anyone used the 3866 Trident Z yet? Looking to grab them and a OCF in the next day or so. Would it be right to assume the 2 x 4gb kit would be E die?
October 18, 20159 yr My kit scales up to 2.2V on air. More I can't set in board's BIOS. Try Asrock,around 2.4V Real Should satisfy Samsung E-die needs
October 18, 20159 yr Try Asrock,around 2.4V Real Should satisfy Samsung E-die needs Has anyone checked to see if there will be any negative effects on the IMC with this kind of ram voltage?
October 18, 20159 yr I ran high memory voltages (2.5V+ DDR3) with every generation of Intel's IMC without any signs of damage to either memory or the processor. So I see no reason to think that things are going to be different with Skylake.
October 18, 20159 yr Trcd/rp, how important is it to have these as tight as they can go, if at all? i.e, is it worth sacraficing 200mhz and possibly one CL value to drop these down a touch.
October 18, 20159 yr Trcd/rp, how important is it to have these as tight as they can go, if at all? i.e, is it worth sacraficing 200mhz and possibly one CL value to drop these down a touch. You have to find a balance,trcd-trp tighter will help 32m for sure but you can run say run little higher MHz with one higher trcd-trp to make up tighter trcd-trp and lower MHz.With xtu trcd not so important well I think it does help but you need to aim for high MHz and play with subs So depending on the bench being used you just need to find a balance high little loose vs little lower tighter ,is a good idea to have all sub timings dialled in for what ever balance your trying this way you can see the difference,change things one thing at a time and check eff take notes and carry on.... Oh and always have rtls,iols correctly don't let one go wild,Cl will be important on 32m as tight Cl = tight rtl,it helps xtu a little maybe but not as much as 32m,would have to test the points difference,it really is all balance Edited October 18, 20159 yr by Bullant
October 19, 20159 yr Perfect Bullant, thanks. Yeah, when i was tightening up my 3600c11 profile on Z170 32m times were reducing until i hit thirds. Pretty sure screwing a few of these tight had an adverse effect but wasn't entirely sure due to running in win10, although seemed fairly consistent tbh. When i did rtl/iol at the end it made a massive difference. I can run 3400-11-18-18 on x99 with these ripjaws v but with all you hynix guys somewhere around 11-14-15 at 3200 it made me ask the question. Chip will be used for 3d so as per Steponz's suggestion i'll switch to 3d physics for testing, can't believe i didn't think of that for myself! School boy error.
October 20, 20159 yr Just a bit of training and winboot, these Sammies sure are flexible. I guess RTL will have to be relaxed for stability, will check this out another day.
October 20, 20159 yr Administrators Nice cas, but seems your trcd is really not good at all, or is this related to proportion on CAS?
October 20, 20159 yr It's related to one stick failing hard at tRCD/tRP, unfortunately. Will do some single stick checks when I have time - doing some testing on X99 in order to differentiate between tRCD and tRP would be interesting as well.
October 20, 20159 yr Administrators I think there is no information on Samsungs on difference on trcd and trp so far, might indeed be interesting - on trcd, this is extremely funny, even my d-die 3200s random kits could do 1866 TRCD18, Team seems to have failed hard especially when I see specs of 18-20 at 3866 at shop. But good sticks on cas, 2k c11 is strong
October 21, 20159 yr Just a bit of training and winboot, these Sammies sure are flexible. I guess RTL will have to be relaxed for stability, will check this out another day. Looks good aero
October 26, 20159 yr Finally got around to testing little 32M all air... and memorys @ 1.67v,little more fine tuning and should see close to 22 flat at cl12 3600 ,will try more soon Kingston AFR
October 26, 20159 yr I guess the trcd could go lower altough it's importance is lower than on DDR3 as far as i noticed.Great run tough !

October 26, 20159 yr I know you guys are keeping tight tertiaries to yourselves but do you mind sharing some loose ones? I'm having issues pushing anything better than 3200C15 and I'm thinking it may be down to my board setting bad auto values. Since I don't trust the values it sets/shows, I don't have a lot to go off of in BIOS. Mainstream GB board, no profiles or anything. Thanks

Thanks I really only just started 32m for effiencey so I have lot to test myself mate,your gigabyte board "gigabyte"needs bios profiles and it's something that needs to be looked at very quickly for ddr4 seeing that most users will try to push memory It just needs a couple of guys to sit down for few days testing and compare setting with each other to confirm it all works.They would need few different ics to test I haven't used your gigabyte board so have no idea how it trains memory or what it's setting mate Nice work aero Edited October 26, 20159 yr by Bullant
October 26, 20159 yr Using the Z170X-UD5 right now. I'm brand new to DDR4 so I have a lot to learn. I didn't get to ease into it with X99! Thank Mr. Bull... hopefully once more and more people get the SOC Force there will be a good DDDR4 tuning thread. Edited October 27, 20159 yr by xxbassplayerxx
October 27, 20159 yr All @ air AFR 1.8v, quick run on retail 4 dimm OCF with P1.50 bios. 4.5 4.0 You guys ready to see what the two dimmer can do ?
October 27, 20159 yr Spent another 20 minutes on it tonight,all air 1.68v,more to come.... Edit ran one more same settings 1.68v,lots to keep testing Edited October 27, 20159 yr by Bullant
