"DDR2-1000 on DDR2-800 memory, fully automated

As part of the ongoing saga that is Tritium, Corsair and NVIDIA just made an announcement about SLI memory, dubbed EPP, or Enhanced Performance Profiles. NVIDIA and Corsair claim that by using aggressive latencies, optimized SPD timings and non-JEDEC commands, DDR2 memory can reach in excess of 1.2GHz on reference AM2 motherboards. As we've mentioned before, when Tritium-certified components are present in nForce 590 motherboards, the system automatically overclocks core components. EPP memory, such as the memory Corsair has announced today, is one of those certified components and will automatically overclock.

NVIDIA's EPP specification guide claims "While the JEDEC SPD definitions have been used very effectively, they are not sufficiently comprehensive for overclocking applications. In such applications there are many parameters that are modified, and no provision exists in the JEDEC SPD specification to allow the system to make these changes automatically." By adding commands in the SPD area that currently have been reserved for future SPD expansion, NVIDIA is able to add hardware hooks that do things like change the memory voltage on the fly. The EPP specification details that two full profiles may be stored in the data area of the SPD, which are then used for storing voltage settings, memory timings, etc.

NVIDIA and Corsair stress the EPP standard is open, and has been submitted to JEDEC for approval. Corsair has two components they are announcing today, both are expected to be available on May 23, 2006 to coincide with the AM2 platform launch. The TWINX2048-8500C5 is a matched pair 5-5-5 2GB kit capable of running at 2.2V. The TWINX2048-6400C4 is a matched pair 4-4-4 2GB kit capable of running at 2.1V. Of course, extended profiles only work on AM2 nForce 590 motherboards and approved BIOSes, so you'll have to mind which nForce 590 motherboards you're purchasing if you plan to use the new memory.

"Enhanced Performance Profiles (EPP) is a memory technology for PC's delevoped by NVIDIA, primarily designed to make overclocking easier. It is a feature of the nForce 5 chipset. Corsair, along with NVIDIA, were the primary parties in developing the specification.

EPP will likely be available only for DDR2 memory modules. It requires support of both the motherboard and the memory module. It uses unused space on the SPD. EPP handles many factors, including memory timings to potentially improve performance. Data can be used by the motherboard's BIOS to automatically configure the system. EPP can handle clock speed, CAS latency, tRCD, tRP, tRAS, memory voltage, and command rate. In addition, a fully enhanced profile will be able to handle drive strengths, fine delays, setup times, write recover time, and tRC. It can also enable the user to overclock the computer's CPU and memory at the same time.
NVIDIA's name for EPP memory that has been qualified for performance and stability is "SLi-ready memory"."

Here is a review demonstrating an average 10% performance improvement in gaming. the only negative they note is the price of the EPP ram (cheaper now, my corsair c4 ram is down to $328 canadian). The 4 games tested showed between 6 and 13% performance improvements.

Here's another one^

"What is EPP? Well first let's take a look at memory overclocking. When overclocking your CPU or memory, there are many factors that come into play to assure stable settings. On AMD specifically, you must worry about using memory dividers properly, along with CPU multipliers to make sure everything adds up to what you expect. It's not as simple as plugging away simple options in your BIOS to give you a good overclock, but you will actually need to use your brain.

What CAS should I use? Should I tighten up my tRAS or leave it at 8? Should I begin to worry about secondary timings? More voltage? Argh! This can be very overwhelming for a new overclocker, and that's where EPP comes in. In simple terms, EPP will take all of the options that enthusiast overclock's use, and meld them into one option. With this one single option, you can overclock your CPU and memory at the same time.

Now the question comes into play.. What about the timings? Sure, overclocking your CPU and memory makes sense, but what about tightening or loosening of the timings to assure a stable overclock? EPP will essentially handle all the timings and other factors as well, which will make this a dream for those looking to get into the overclocking scene."







In a nutshell (described best by OCZ at their launch), its plug and play overclocking.
