The care and feeding of your Haswell's memory controller

X-bit Labs did testing of a variety of memory speeds on Haswell to determine if there is a point of diminishing returns at which point your well earned money is no longer bringing you better performance.  By setting up tests of two different DIMMs at set speeds, in this case DDR3-1600 and DDR3-1866 and varying the CAS Latency they tested to see if higher speeds or lower latency gave the best performance.  Using both synthetic benchmarks as well as gaming tests they determined that frequency is the key to better performance which makes sense considering the theoretical top frequency of 2933 MHz.  Check out all the benchmarks in their full review.

"The development of the new processor microarchitectures goes on and frequencies of contemporary types of DDR3 SDRAM grow as well. Is there any sense in using high-speed memory with modern Haswell processors? To answer this question, we have analyzed DDR3 frequency and timings influence on LGA 1150 platform performance."

Big memory from Mushkin ... 16 or 32GB, your choice

Subject: Memory | August 14, 2012 - 01:18 PM |
Tagged: ridgeback, redline, Mushkin, ddr3-1866, 32GB, 16GB

You can pick up two DIMMs with the 16GB kit or four with the 32GB, either way you end up with DDR3-1866MHz @ 10-10-10-27 running on 1.5v, with a lifetime warranty to boot!  When Overclockers Club went to work the two kits did end up showing some difference as the 16GB kit hit 2288MHz @ 11-11-12-28 2T while the 32GB only managed 2202MHz @ 11-12-12-28 2T.  If you check out the Mushkin Redline series on NewEgg you will see a wide variety of models, so pick the ones with the lowest latency for the best performance out of the box as well as more overclocking headroom.

"Looking at these two kits of memory from Mushkin shows that it has another pair of kits that deliver performance indicative of their specifications and more. First up are the distinctive good looks and functionality of the cooling solutions employed on each kit. The 32GB kit part number 994071 uses the "Ridgeback" design. This robust heatsink package uses a series of angle shaped (think Mushkin logo) fins on top of a thick body to effectively wick away the thermal load generated by these high density modules. Packing them into a four DIMM configuration like used in the testing will allow a higher heat load to be retained but is nothing to be concerned about. Using an air cooled CPU cooling solution would fix that issue as once air starts moving over the modules they cool down fast."

The new Vengeance high-performance memory upgrade kits for laptops are designed to work with any PC or notebook which accepts standard DDR3 SODIMMs, and are backward compatible with notebooks and laptops which use first-generation Intel Core i5 and Core i7 processors. Even on older notebooks, customers can still take advantage of the ability to upgrade to 8GB of memory using only two memory slots, and enjoy the confidence of Corsair's renowned service and support.

"As more complex applications and games are available in the market, many laptop users are looking for an easy way to improve their system performance in order to have the best experience." said Thi La, Vice President of Memory Products at Corsair. "Our new Vengeance high-performance laptop memory kits allow performance-minded customers to boost their memory performance and capacity in an instant." 

Size Speed # of DIMMs Part Number
8GB 1866MHz, 10-10-10-27, 1.5V 2 CMSX8GX3M2A1866C10

Overclocking Llano just makes sense, but the RAM not so much

Subject: General Tech | July 25, 2011 - 12:30 PM |
Tagged: llano, ddr3-1866, a8-3850

Most reviewers made a financial decision when pairing RAM to review AMD's new Llano A8-3850 processor.  Most chose 1333MHz DDR3, since when building a low cost PC most users are going to choose the lower cost as opposed to spending half the budget simply on DDR3.  After seeing significant overclocks produced by a variety of testers, The Tech Report thought it would be interesting to see the impact of high speed RAM on the performance of an A8-3850, especially the graphics portion.   As it turns out, the decision to go with lower cost RAM made a lot of sense as the the graphical performance did not benefit from faster RAM.

"Will 1866MHz memory make a big difference to the performance of the AMD A8-3850 APU? How does power consumption look without a discrete GPU involved? We aim to find out."

The asking price of G.Skill's DDR3-1866 sniper kit is right on target

Tagged: G.Skill, sniper, ddr3-1866

G.Skill's Sniper 1866Mhz @ 9-10-9-28 bear a rather unique heatsink, keeping in line with the odd military theme many hardware companies have chosen to go with in 2011.   The rifle motif might not add to the cooling but for those who build a system to be pretty the looks might be more important.  Benchmark Reviews didn't get into overclocking this DIMM kit but they certainly had no problems running them at their advertised speeds. At just $100, this kit is not a bad choice for a system using dual channel memory.

"RAM is one of the basic building blocks of a computer system, and although the technology has changed over the years the same basic idea of quick temporary storage has been RAM's main purpose since its inception. Gamers have always wanted the fastest speeds possible but unfortunately that meant that many of the fastest kits were very expensive. Since the introduction of DDR3 prices have plummeted and speeds have skyrocketed and a good set of 2 x 4GB RAM can be had for under $150. G.Skill understands this and has SKU's designed for every price range. G.Skill's most recent addition is its Sniper series of which we will be looking at the 1866 MHz F3-14900CL9D-8GBSR kit which is well priced $104.99 providing users above average speeds with relatively tight 9-10-9-28 timings. Benchmark Reviews will determine if this RAM is worth its price or if users are better off getting slower, less expensive SKU's."

Give your Sandy Bridge laptop a jump on the competition with the new Kingston HyperX DDR3-1866

If you prefer your laptop to be ultrapowerful not ultraportable then Kingston has a SODIMM kit that you are going to love.  8GBs of DDR3-1866 in two SODIMMs with timings of 11-11-11-32 2T, the star of the 6 new HyperX DDR3 kits from Kingston.  That will give yor laptop a boost many desktops still don't have.  Legit Reviews were very impressed with the performance jump they saw on their Sandy Bridge laptop, calling it the next best thing to upgrading to an SSD.

"The performance numbers from upgrading to the Kingston HyperX Plug and Play 8GB DDR3 1866MHz memory kit was insane. We saw performance gains from 6% to 86% depending on the benchmarks with the largest performance gains coming from graphics intensive games. Who would have thought that the area that gained the most was the frame rate in games? If you want to get better performance out of the Intel HD Graphics 3000 GPU on your Sandy Bridge laptop this is more than likely the best way to go about it. You can literally feel and see the difference in everything that you do on the system, so this is an ideal upgrade for those that want 8GB of memory and better performance..."
