[HowTo] SO-DIMMs Extreme: Boost 1600 to 2133 and beyond / JEDEC & XMP

*OFFICIAL* Alienware M17x Benchmark Thread - Part 4
"Has Anyone already bought 1600 mhz 9-9-9-24 Corsair Vengeance RAM? Could anyone post a screenshot so I knew timings for 1333 speed?" - This question was the first thing I wrote in this thread. Since then this thread became much more useful than someone could expect at the beginning. Here you can find almost everything of how to improve your Corsair Vengeance RAM.
Be my guest

Conclusion of what can be made and link on Corsair 1866Mhz improved *.thp profile.


Conclusion of what can be made and link on Corsair 1600Mhz improved *.thp profile.


Summary what we have already got:
1) Screenshots of stock 1600 Mhz Corsair. Thank Nemix77 please
2) Screenshots of stock 1866 Mhz Corsair. And link on stock *.thp profile. Thank GalaxySII please
3) How To videos of modding (and therefore speed and performance improving) Corsair 1866Mhz RAM. Possible to do with 1600Mhz too! Thank TURBODUDE!!! please
4) Memory modules used and their Datasheet
1)1600Mhz Corsair (Nemix77's):
JEDEC Timings for 1066Mhz mode are 6-6-6-16 with 26(RC) and 1T for 8GB of RAM. Possibly will be 2T with 16GB. tRFC is 128 whatever it means.



CPU-z JEDEC screenshots are here



2)1866Mhz Corsair (GalaxySII's):
JEDEC Timings for 1066Mhz mode are 6-6-6-16 with 26(RC) and 2T for 16GB of RAM. Possibly will be 1T with 8GB. tRFC is 150 whatever it means.



AIDA benches show: 19064 MB/sec reads 18749MB/sec writes and 21412 MB/sec copies. Also possibly faulty JEDEC timings by CPU-z. All is in attached screenshot (too wide)

I have it ordered, will be pick them up this weekend.

[James D]

Thank you. Will be waiting...

@ James D

I recently changed the order and got the Corsair DDR3-1866 instead.

The ram is on back-order but will arriving hopefully sometime this week.

[GalaxySII]

I have ordered but 1866s 4x4GB

[James D]

well franly I think that it will give not much performance difference 1866 vs 1600 especially for double price. But fine. Will wait longer.

I don't understand the need for this fast RAM in Intel setups. It makes very little difference in anything except for RAM limited applications which are few and far between. So many other bottlenecks.

[James D]

why are you saying that AMD is best for it?

Well with AMD benefits are minor too, only the IGP gets some performance benefits from it. Even then it's limited.

I found this article a couple days back Maximum PC | Is Your Gaming Laptop's RAM Slowing It Down? which made me change my mind on DDR3-1600 and thus I went with the DDR3-1866 instead since both are on back-order.

I don't plan on upgrading to Ivy Bridge and thus the price difference between DDR3-1600 and DDR3-1866 maybe worth it since it could potentially help the Intel HD 3000 IGP last a little longer before another laptop upgrade is imminent.

Besides, it would better to spend $50 more ATM then spend a lot more in the future when when DDR4 is standard on all laptops and DDR3 becomes obsolete driving prices up, not to mention it'll probably be a lot harder to find premium DDR3-1866 by then.
