New Memory, any suggestions on setting it up for Benching.

Hey guys, I just picked up some new Memory and was hoping that you could give me some tips on setting it up for benching. I have not changed any of the settings or timings other than setting XMP in BIOS.
Its a set of Corsair Dominator GT's 2X4Gb, CL9 @2000. If you had any detailed Information on how to get more out of it and a general Memory adjusting crash course I'm all for it. I've got questions as well like when to apply voltage increases and what exactly the will help achieve(Freq or Timings), and what to look at and set in other more detailed timings. I'm fairly new to memory, as well as overclocking in general. I have a pretty good grasp on what it is that im trying to do, just not so much on the steps that i need to achieve it.
Thanks Everyone

I had no tests on similar IC except new Vengeance but it's higher density IC and was really bad for OC in general -> http://www.overclockers.com/forums/...el-2x4GB-DDR3-1866-CL10-1-5V-CML8GX3M2A1866C9

Hi Mr Woomack,

I am on the same Memory learning crusade as the OP

I have these,

http://www.overclockers.com/forums/showthread.php/728364-Team-Group-Xtreem-8GB-DDR3-2666-C11

I use them exclusively for benching. My Primary Benches at the moment are the Rookie Rumble Benches (GPUPI, Hwbot Prime, XTU) and Secondary Aquamark (as i'm convinced i can take top spot with my R7 240)

Although the review/thread is quite comprehensive, do you think you could give some recommendations for what i should be aiming for considering my current benching projects and total noobness to Memory Tuning.

Thanks in Advance.

Thanks for the quick reply and the examples. It helps alot to have something general to go off of.
Ill give those a shot, And i assume try to shoot for 1T if it is stable.
Could you explain a bit about voltages to me. I see in the examples that you just give a range, Is it that simple? try to get the lowest stable voltages and dont go higher than 1.75~.
Aside from that, Ill report back with the outcomes.
Thanks again.

I wont be able to help you out as much as others here but, once i get through testing a bit and have some data, Ill try to throw a thread together with what ive learned.

@TuKr
You can try higher voltages but I doubt that on this IC anything above 1.75V will help. For benching you don't have to spend time on checking how low you can set voltage. If it's working and it's not too high then it's fine. You aren't running 24/7 100% load tests, only quick tests.

@Acce55
This kit is not the best for benching as it's single sided ( or you have 2x8GB then it's much better ). Single sided kits are usually 10-20% slower at the same clock as double sided.
My Team 2666 C11 kit was on Hynix MFR and I think yours will be the same.
Settings from these threads should work:

http://www.overclockers.com/forums/...dentX-2x4GB-DDR3-2933-CL12-F3-2933C12D-8GTXDG
Team 2666 C11 can be even better than some of them.
So generally you go for ~2666 CL10-12-12 or 2800 11-13-13/11-14-14 or 3000 11-14-14/12-14-14 and maybe 1.75-1.85V for benching.

Best for benching from newer kits are double sided Samsungs ( HYK0, HCK0, HCH9 ). Something like 2400 10-12-12 , 2400 9-11-11, 2600/2666 10-12-12 ... but most of them are not available for longer and all brands except G.Skill are not manufacturing them for 2 years+. Some weaker Samsung series are in various kits from couple of brands like Corsair but for example Team Group has no Samsung kits in mass sales since end of 2012. Geil, Mushkin, Kingston, Avexir and some others the same. Corsair had last good Dominators on Samsung IC at the end of 2012. Later only average kits randomly mixed with Nanya, Micron and Hynix.

From older kits it's good to look for PSC from higher binned series like 2133-2400. All good PSC are in 2GB modules so 2x2 and 3x2GB kits. these are available only on auctions and best kits are highly overpriced but still can find something good in reasonable price.

or you have 2x8GB then it's much better

Yes, i have the 2x8GB - Sorry didnt make that clear. Sticker as follows



Thanks for the feedback.

With 2x8GB kit you are in much better situation looking at performance. I had 2 kits of 2x8GB Patriot based on Hynix MFR so should be about the same as only MFR and best CFR were in 2666 C11 kits.
Here is review of these Patriots: http://www.funkykit.com/reviews/mem...-and-venom-red-memory-review?showall=&start=4 Review was on older platform but I made them work up to 3200 for memory valid and I took 1st spot on 32GB kit in hwbot competition
Anyway I would try 2600-2666 10-12-12, 2800 10-13-13, 11-13-13, 11-14-14, 2933 11-13-13, 11-14-14, 12-14-14 up to 1.85V for benching , maybe 1.75V for longer work. Performance is not much worse than better Samsung kits but tRFC has to be high like 350 to make higher clock what lowers performance in some benchmarks. Still not bad overall. Even at 2666 CL11 this kit should perform good.
Play some with sub timings. Try to lower them one by one and check how much it's helping. I don't remember what motherboard you have but for sure there are some settings to make memory work slightly faster.

Alright, Here are the results.
I could not get any of the 2400 settings to post, as well as most of the others, so i moved on to the 2600. Out of all of the test, those were the only 3 that would pass any kind of testing. I Tried 2T on all of them and if they benched then i tried 1T. I may go back and try for 2666 but at the same time I was at 1.74v with 2600. As for all of the other timings within the ram settings are there any that would improve my score. I know of DRAM Refresh interval, if you increase It it can help increase your ram efficiency in benches and responsiveness, But anything that stands out as the next step?

I can barely see anything on the screenshots but I generally see what you set there.
On Haswell keep CR 1T. It will work without problems. To stabilize 2600 try higher tRFC. It's good that you made it work so high. Most Nanyas won't boot at 2200+.
Check 2600-2666 11-13-13-35 1N up to 1.8V. If you make it run a bit more stable then check timings. Check if you have option DRAM swizzle or something similar. 2 settings for each memory bank if I remember it right. Set all to enable. Also try Maximus Tweak or whatever it's called on your board to 1 or 2 ( usually it's 1st option in memory timings tab ).
From Digi+ window set higher DRAM VRM frequency ( can be on max ) and DRAM max current to something higher 120 or 130. I have no idea if it's going to help but it's worth to try.
If you won't make it run more stable then check something like 2400 9-10-10, 9-11-11, 9-12-11 or 10-11-11, 10-12-11, 10-12-12.

Ill try those as well, and Yeah, you are spot on with those option names, I have a total of like 5 swizzle options, I had maximus tweak set to mode 2(improve overclocking) Ill go into extreme tweaker and change the DRAM limits and Vrm freq. It may help, A few of them would power on and hang at 55 on the Qcode, others would powercycle so it may help on the ones that Hang. Thanks again. Sorry about the screens. I probably didnt need to change the res, but i forgot that they are screens. The Ram Pics i took with my phone and had to resize. I didnt think about it and resized the screens the same way.

Just make sure you are testing one thing at a time so you know which option you changed made it work. Otherwise, its just throwing stuff at the wall.

I'm currently using Asus Max VII Gene, i presume the memory setting advice is the same as for Tukr's board?

All Maximus and Rampage boards have almost the same settings. Depends from used chipset there are more or less memory timings and for example instead of Rampage Tweak there is Maximus Tweak ( exactly the same ). Rules are the same and most standard ASUS boards have similar options too ( just less ).

Is this the model number of the Samsung ram that's good Woomack? M378B5673H0-CH9? A buddy has it in his old Alienware.

It's old OEM Samsung , looks like 2GB stick. You are looking for 4GB sticks HYK0, HCH9 or maybe better HCK0 but these are sometimes average. HYK0 IC was almost only in Samsung "Green" 1x4GB or 2x4GB 1600 11-11-11 1.35V or in TridentX 2400 CL9 , 2600 CL10 and 2666 CL10. Also in very overpriced Corsair Dominator Platinum 2400 CL9, 2600+ CL9/10 but these are rare and were not really in mass sales ( available mainly directly from Corsair ).
Also Team Group had Vulcan 2400 10-11-11 and Xtreme 2400 9-11-11 and 10-12-12 kits based on good Samsungs but since 2013 all their kits were based on Hynix IC ( info from their representative ). So all newer 2400 CL10 and 2666 CL11 Team Group kits were on Hynix MFR.

My advice would be to look for:
- TridentX 2x4GB/4x4GB 2400 CL9 , 2600 CL10, 2666 CL10
- PSC based RipjawsX, Pi or Flare 2x2GB 2133/2200 CL7-10-10, 7-10-7
- PSC based Patriot 2400 CL9-11-9 2x2GB
- Corsair Dominator GT 2000 8-9-8 or 2133 9-10-9 or something similar with low CL <- these PSC are Rev 7.1 http://forum.corsair.com/v3/showthread.php?t=68811

There are some other kits too but generally it's high binned low CL Samsung or higher binned PSC. All of them are out of production for longer but are still on auctions.

Does it go off the last four digits of the model

there's set of TridentX 2400's cl9- over at Hwbot
