Samsung green with max vi extreme 4770k

Hey, just wondering as the memory guru if you could give me idea of ram timings and speed on the new platform.

The ram is stable at least up to 2100 MHz cl9 (which is what I had it at on the x58). But the old 920 wasn't happy with it.

I've heard a lot about the new ram having newer version three XMP profiles. I'm sure the green doesn't. So what would your advice be on getting the most out of it on the new platform be? I'm fairly ok with main timings etc, but I'm going in a bit blind on the 1150 setup!

I have also heard reports of the memory speed being limited by the CPU overclock, but then some have got 4.9 with 2400 MHz ram. Is this your experience?

Much appreciated!

You will probably be able to hit CL9 2300 up to about 4.8GHz (if you can get that high).

Once you start hitting 5GHz+ you may need to slacken the timings and drop the speed a bit for real high end benching, depending on the IMC of the chip.

Samsung Green was C9 2400 for me on M6E. 9-12-12-21 1T and then 5-108-auto-10-4-26-4-5-6 or 7. Then 5-4-5-20-5-4-4-4-4 12-12-12 I think. Thats off memory!!!

Oh nice one! Thanks a lot!! I'll let you know how I get on

8 Pack · 20 Jun 2013 at 23:24

Ok good.

If your not stabl ego with thirds of 6-5-4-20-6-4-4-6-4 13-13-13.

james_2k · 21 Jun 2013 at 11:48

Will do! Much appreciated man

8 Pack · 22 Jun 2013 at 16:23

No problem. Post how you go!!!

james_2k · 25 Jun 2013 at 12:45

nowhere near getting the ram stable at those timings

running @ 4.75 (44 cache) - 1.357v

memory @ 1.65v seems to be unstable at 2222+ cl10/12/12/21 with 1.3 v ring.

any ideas on what to bump for a shot at 2400?

8 Pack · 25 Jun 2013 at 21:18

Hold on 16gb?? 4 sticks??

I tested only two.

Go 10-12-12-28 1t First and set Maximus Tweak mode1. Set Cache Volts to 1.15v and SA, IOA and IOD to around the same. Remove CPU overclock when working on RAM too.

See where this gets you and report back. If you can show me the Auto timings at 2200 and 2400.

james_2k · 25 Jun 2013 at 21:35

yeah 16 (4x4)

ill give that a try!

8 Pack · 25 Jun 2013 at 22:12

Try TRFC around 300 to start with too.

james_2k · 25 Jun 2013 at 22:32

Ok at the moment have 2222mhz, with 1.6v 1.268 cache and auto sa ioa ios

9/11/11/26 1t
Then, 7 108 7936 25 7 26 5 8
6 6 6 24 5 5 4 7 7 26 14 9 9 9 2 2

All seconds and thirds auto except for 108 which was 147 on auto.

8 Pack · 27 Jun 2013 at 14:31

ok.

The tuning options are 5-108-7936-10-4-26-4-5-7 for seconds. Try these first. Then try go TWCL 6.

james_2k · 27 Jun 2013 at 14:35

Ok will do, twcl is the first second?

Thanks!

8 Pack · 28 Jun 2013 at 11:03

nope. Bottom second Timing.

james_2k · 28 Jun 2013 at 21:31

Oh ok, just got back from work and am trying to get 2222 stable. Regarding primary timings, do you think 9 10 10 26 would work?

james_2k · 28 Jun 2013 at 22:30

ok timings as they stand:

2222mhz
9/10/10/26/1

5/108/7936/21/4/26/5/8

6/6/6/24/5/5/4/7/7/22/14/9/9/9/2/2

as your 2400 thirds were tighter im going to try them. i couldnt get twcl any lower than 8 with those timings or no boot.

james_2k · 28 Jun 2013 at 22:54

just tried some tweaking. (lots of restarts!)

this is at 1.6v with around 1-1.15 v on the voltages you mentioned.

here are the current timings. im not sure if some are too high and some too low, affecting some other ones etc. if you could take a look id much appreciate it, cheers!

8 Pack · 2 Jul 2013 at 14:16

TWR shopuld go 12 or 10, TRAS should go 21. I would test but perf may be better 9-11-11-21 1T, 5,108,12,4,26,4,7 Then go 4-5-4-20 if you can.

For bandwidth without sacrificing too much in primary's your trying to get TWCL 7 and tRDRD 4. I find Sammys like 9-11-11.

james_2k · 2 Jul 2013 at 18:38

Ok thanks a lot.

Have got the timings to, 9/10/10/21. 5/108/7936/12/4/26/4/5/7. 5/6/6/20/5/5/4/7/7. 10/10/10

At 1.6v

No luck getting lower than 7 on the last second or any lower on the first three thirds. Although the first third going down one got around 2000mb/s read speed increase which was amazing hehe.

Also the second and third primaries made no difference whether at ten or eleven to the ability to lower those other ones you mentioned so I left them at ten in the end.

Speed wise, it's benching at 27800 read 35000 write 30800 copy and 41 latency in Aida 64 latest version. How does that look? Anything glaring? Cheers!
