OCZ PC2-9200 Flex XLC Specifications

OCZ is a well-known supplier of enthusiast parts. While they are best known for their memory targeted at the enthusiast, OCZ also provides an extensive line of power supplies and CPU coolers, along with more value oriented memory. As recently seen in Taiwan, OCZ also plans to introduce custom water-cooling parts in 2007. With that in mind, the OCZ introduction of water-cooling ready enthusiast memory appears to fit the total picture.

OCZ tells us that then new Flex XLC memory is not designed just for water-cooling. In fact, with air-cooling alone Flex XLC can reach most of its potential. It is designed to be the fastest memory available from OCZ whether run on air or water. One thing that is clear is that Flex XLC does not look like other high-end DDR2 memory.


Quoting from OCZ literature the "Flex" in Flex XLC represents the "...innovative 'flexible' design, which gives enthusiasts the option to run these modules passively or water-cooled via the integrated liquid injection system for maximum heat dissipation."


The fin assembly was designed for very effective air cooling. When water is used even better cooling is possible. The hybrid copper and aluminum water channel and fin design is designed to cool effectively whether air or water is used for cooling. As the diagram indicates, water-cooling is optional.


The Flex XLC DIMMs come ready for water hookup. The 3/8" entrance/exit nipples are an integral part of the cooling block and a standard design for water hoses. The flat top design of the heatsink/fins also makes it a "flat" surface for placing a large cooling fan over a pair or even four of these DIMMs. The Flex XLC dimms are thin enough that they can be fitted in side-by-side memory slots. We tried them on several boards and four dimms should fit just fine if you want to add even more memory. OCZ builds the new memory with specially binned Micron D memory chips mounted on an 8-layer PCB. The special binning, ultra low noise PCB, and hybrid heatsink design all contribute to overclocking capabilities.

OCZ PC2-9200 Flex XLC Memory Specifications
Number of DIMMs & Banks 2 DS
DIMM Size 1GB
Total Memory 2 GB
Rated Timings 5-5-5-18 at DDR2-1150
Rated Voltage 2.35V
(2.4V +/- 5%)

Flex XLC is currently only supplied as a 2GB kit (2x1GB) rated at PC2-9200 (DDR2-1150). This is the highest memory speed rating for DDR2 that we have ever tested. While Flex XLC is rated for 2.35V it is covered by the OCZ Extended Voltage Protection (EVP). This extension to the warranty provides a lifetime warranty against failure as long as the memory is operated at 2.52V or below.

While the form factor is new, it is worth repeating that OCZ is using specially binned Micron D memory chips in Flex XLC. That means the leading performance we routinely see with Micron memory chips should also be found in Flex XLC performance - along with the additional overclocking headroom designed into the product with aggressive binning and a hybrid cooling design.

    There is no "for shits and giggles" about it, it would help. How much it would actually help would be open for debate (until someone actually tested it).

    For one, it would help, because, IF you for example had air coming in from the bottom, and air exiting out through the top, you would be using convection to recycle cooler air from the outside, and the heat would travel out through the top. To some small degree, you wouldn't even need a pump to accomplish this. This would also keep hot air from recycling, well, at least concerning *from* the memory(to a small degree) , which wouldn't mean a whole lot.

    Now, if instead of using convection, you use forced air, whether chilled or not, dependent on the CFM pushed through, you *could* reduce the temperature on the heat spreaders drastically. This may not cool as well as water, but there would be no chance of water leakage either, and would result in a definite improvement. Granted, I can not see people wanting to go out an buy a <insert brand here> air compressor, for what whatever amount, when it would be cheaper to go water(which, its self, isn't cheap either). I've priced components for a good water cooling system, and we're talking around $400 usd, for a decent setup, which IMO, would be better just spending the extra cash on a better/faster CPU(if possible). Less problems, and hassle.

    Never seen a Dell that uses a plastic "funnel" over the CPU, without a CPU fan directly over the CPU? They exist, and they do very well in keeping the system very cool. Same concept, on a smaller scale.

    Though the idea is interesting, I think you would be better off pushing air over the cooling fins the usual way, than to push air through the water cooling intake. Remember that air and water have very different properties and the cooling interfaces has been designed to optimize each of those elements.

    It could be an interesting experiment I must admit, but I suspect you would get just get a lot of hissing noise from the end of the hose - and not a lot of cooling...

    If you pumped cold air in through the block, you will get condensation in the lines. Reply

    Erm, no you wouldn't. Condensation only forms when the air is cooled down by something, such as on a cold window in a warm room, because cooler air is unable to hold as much moisture as warm air so excess moisture has to be dumped as condensation when the relative humidity reaches 100%.

    Pumping cold air through the block carries no risk of condensation because the air will be warmed rather than cooled. In fact it would be an effective way of removing any moisture because the air warmed by the block would have a fairly low relative humidity.

    Hell, I'd even venture to say that if you forced room temperature air through these fast enough, even on a warm day, the results would be great. Granted, you would have to be strategic about it. Reply

    I realize you don't normally test water cooling (or cooling products in general), but it seems one of the major points for this RAM is that it is ready to be used with water cooling. Rather than speculating about if it will help or not, how about actually testing it? Seems like this RAM would be great for people looking to build a silent system, as you now don't have to worry about the RAM overheating either with water cooling.

    Also, this wasn't mentioned in the article, but can you fit two DIMMs next to each other? Meaning, could you go all the way to four DIMMs? Reason I ask is that if you can't then there are going to be some boards where this RAM won't work at all in dual channel mode. Hopefully OCZ wasn't so shortsighted as to make the DIMMs take more than a single slot width, but at the same time I don't know how you get effective water cooling without the HSF getting quite a bit thicker than the typical heatspreader.

    We should have mentioned that the OCZ Flex XLC is thin enough that 4 dimms can be fitted in standard memory slots. We tried side by side slots in a number of boards and the dimms fit fine side-by-side.

    We considered testing with water also, but we did not have the correct fittings available, it would have taken a while to get the fittings we needed, and we wanted to get the info to our readers as fast as possible. OCZ emphasizes the Flex nature of the memory, and we thought you would want to know about the outstanding performance on air with Flex XLC.

    Perhaps we will relent and test with water in a future review, but we're not completely sure we want to go in that direction. We generally find we can overclock using air cooling at speeds similar to some other sites who insist you can only cool with water.

    The "silent" aspect is a good argument for water cooling, but most water systems still have a fan to cool the liquid and a pump for recirculating the fluid. Some water cooling systems are therefore about as "noisy" as a good air-cooled system - though we do agree that many water cooling systems are very quiet.

    no doubt the water cooled feature should have been tested.

    I'm also wondering how the heatsink is designed - does the water flow down the front of the stick over the actual memory chips?

    If you look at the last page on the "Pre-CES Taiwan 2006, Day 1" article that's exactly what they had in there. Reply
