AnandTech Benchmarks Memory for Servers

Subject: General Tech, Memory | January 1, 2014 - 03:37 AM |
Tagged: RDIMM, ram, LRDIMM

In all honesty, outside of on-die graphics solutions, memory speed and latency are often neglected. My only requirements for RAM beyond the recommended specs for my motherboard and processor has been a heat spreader of some sort (and that is just because I have bad luck with several DOAs on unshielded RAM which I assume was handling problems).

But this story is for the enterprise users.

Johan De Gelas of AnandTech decided to test a few different configurations of RAM including both RDIMM and LRDIMM modules. LRDIMMs are significantly more expensive than the cheaper RIMM modules but, especially if you could reduce server count (and active licenses of software running on them) they wanted to investigate whether it could be cheaper overall. This would not be the case if software is completely CPU-limited... but, again, when is memory the limiting factor?

That is where the benchmarks come in. Among the handful of measurements performed, they simulated thousands of users accessing a CDN with between one-to-three-quarters of a terabyte of memory. In both cases, 768GB of LRDIMM memory had significantly higher throughput and significantly lower latency.

As always, check out the review if you are interested.

Tagged: DDR3-2400, patriot, Viper 3, Black Mamba, 16GB

Patriot's Viper 3 Black Mamba PC3-19200 16GB kit will set you back $225 to purchase which is a large premium over DDR3-1600.  Base timings of 11-11-11-28 are not that much higher than DDR3 which might help these DIMMs live up to their premium pricing as will Intel's XMP 1.3 memory profile.  To find out how it compares to other 2400MHz RAM as well as slower kits you can head over to Neoseeker to read their full review as well as see what kind of overclock they managed to attain.

Antec's High Current Pro 850W Platinum is worth its weight in ...

If high efficiency is your preference then the Antec High Current Pro series is probably familiar to you.  Legit Reviews just reviewed their most powerful model, providing up to  850W and sporting four 40A 12V rails to power the six PCIe power connectors.  The fully modular design is great for keeping your case clean and the clear labellings on the PSU ensures you can properly balance the load between the 12V rails.  It performed admirably but the retail price of ~$200 did disappoint Legit Reviews somewhat.

"Today we will be having a close look at the 850W version of the High Current Pro series, the HCP-850. The HCP-850 is a modular power supply with a very long list of features and a seven year long warranty. As all of the High Current Pro products, the HCP-850 also comes with an 80Plus Platinum certification, the highest currently available on a retail product..."

Just how special is Kingston's 10th Anniversary HyperX Kit

Subject: Memory | October 3, 2013 - 05:31 PM |
Tagged: kingston hyper x, kingston, HyperX Genesis 10th Anniversary Special Edition, DDR3-2400, 16GB

Kingston 10th Anniversary HyperX 16GB 2400MHz brings you a DOTA 2 tourney but does it also bring performance to your PC?  This 4x4 kit runs DDR3-2133 @ 11-13-13-30 or DDR3-2400 @ 11-14-14-30 which implies very good performance from these DIMMs at stock speeds.  Of course Overclockers Club were not satisfied with stock speeds and with a little tweaking managed to hit DDR3-2522 @ 12-13-13-33 which was enough to give them a boost in performance without causing instability.  Another feature of these DIMMs many will like is the low profile of the heatspreaders which will allow a much broader choice of CPU heatsink.

”During my testing I found that while the kit ran flawlessly at its rated speed of 2400MHz, they just did not offer a whole lot of headroom above that, even when pushing 1.75v+ through them. Seeing how running a 125MHz or 166MHz strap is a bit easier on the memory controller, I swapped to the 125MHz divider and started upping the frequency up a little at a time until reaching the maximum clock speed on the HyperX modules. I left the memory sub timings alone and controlled by the board, adjusted the primary timings to 12-13-13-33, adjusted the DRAM voltage to 1.70v, started up again, and finally reached 1260.2MHz or just over 2520MHz for a 120MHz gain in clock speed. That represents about a 5% gain from just testing and tweaking. What I found was that the Kingston HyperX 10th Anniversary modules performed well even with the boosted clock speed. The low profile heat sink makes sure there are no restrictions to the CPU cooling solution used.”

SK Hynix Will Resume DRAM Production At Chinese Plant Soon

Subject: Memory | September 7, 2013 - 01:43 AM |
Tagged: manufacturing plant, Hynix, DRAM

SK Hynix experienced a fire at one of its DRAM manufacturing plants in Wuxi, China on September 4th. Initial reports suggested that the plant would need major repairs as the large black smoke cloud above the facility appeared rather ominous. Because the plant is responsible for approximately 40% of Hynix's DRAM output (which amounts to 12% of global DRAM supply), the plant shutting down for repairs would have severely disrupted the memory market and pricing of both individual chips and memory modules.

Fortunately, the fire was much less severe than it appeared. SK Hynix recently released a statement indicating that the fire was concentrated in the air purification hardware connected to the rooftop which resulted in the large smoke plumes. There was “no material damage” to the machinery used on the manufacturing floor in the production of DRAM chips. The damage was relatively minor and the facility will resume production shortly following minor repairs.

A SK Hynix spokesperson Seongae Park was quoted by Bit-Tech in stating that “we expect to resume operations in a short time period.” Also, Hynix indicated that its overall supply volume and DRAM production would not see a major drop.

This is good news for PC OEMs and enthusiasts as it means prices for the chips and resulting hardware should not spike and will stabilize sooner than originally expected.

Is AMD's Radeon Memory Gamer Series worth the premium?

Subject: Memory | August 16, 2013 - 06:37 PM |
Tagged: radeon memory, ddr3-2133, amd

Neoseeker is testing AMD's Gamer Series memory which runs at 2133MHz with timings of 10-11-11-30 at stock.  They tested the memory against six other kits at stock speeds and overclocked to 2600MHz @ 12-13-13-33 and were pleasantly surprised to see it sitting at the top of the test results in most cases.  They chose to test on an Intel platform and saw absolutely no compatibility issues though it would be interesting to see these DIMMs tested on an AMD rig as well.

Hot on the heels of Haswell comes high speed DIMMs from most manufacturers in much greater quantity than previously available.  For instance the Corsair Vengeance Pro 16GB 2400C10 Memory Kit, a pair of 8GB DIMMs with timings of 10-12-12-31 at stock and part of a family of RAM that runs from 8GB to 32GB and is available in speeds of up to 2933MHz.  MadShrimps just reviewed these DIMMs and while they didn't have much luck overclocking them they were more than satisfied with the stability at stock speeds.

MS_IMG_8212.jpg

"CORSAIR just recently launched their brand new Vengeance Pro series kits. These are designed to set new levels in value and overclocking. With a new stylish and aggressive looking heat spreader design, available in four different flavors: Blue, Gold Red and Silver color. The current products range up from 8GB to a whopping 64GB kit. The rated speeds start of at 1600MHz up to 2933MHz for the flagship version; especially the high end versions are being optimized for Intel's 4th generation Haswell processors. At Computex 2013, CORSAIR already showed higher specced versions, though if these will ever hit the shelves remains a big question. The today's reviewed Vengeance Pro kit is one of the more enthusiast targeted kits, comprising out of two 8GB 2400MHz Cas 10 DIMMs, with a red accent finish."
