Legion Hardware
"First off the OCZ DDR2 PC2-9200 Flex II 4GB Series is certainly the most impressive memory we have ever seen and as far as memory goes this kit has it all. The fact that we were able to hit 1246MHz (96MHz above spec) using nothing more than the air circulating the case, is impressive. Then when using the water-cooling feature we managed 1266MHz, which was even more impressive. While water-cooling did slightly improve the overclock, it will also help maximize stability during the warmer months of summer.These modules are certainly going to appeal to every kind of enthusiast, whether you are an overclocker, case modder or gamer, we imagine the Flex II memory modules are probably at the top of your wish list. Overall we have enjoyed playing with the new Flex II memory and for once this is a high-end product that we could easily justify spending our own hard earned cash on!"


TweakTown
"OCZ is by far one of the biggest supporters of overclockers out there. Overclocking of OCZ memory is always fun; managing to get high speeds is usually not a problem. We managed to hit the rated 1150MHz with the 2.1v standard, but pushing the memory to 2.25v in the GIGABYTE X38-DQ6 allowed us to increase our overclock to 1196MHz with an FSB of 299MHz. DDR2 hasn’t died, and one thing is for sure, companies like OCZ will really push the limits of DDR2 technology as long as it’s with us. Those who want a much more silent system can look to OCZ who has come to the party with a very impressive memory kit here. The Flex-II series should improve on the Flex design with dual paths for the water rather than a single, allowing for a more total cooling solution while still keeping the noise within the system to a minimum, thanks to the use of liquids. The added flexibility of still allowing air cooling users to have the advantages of this memory is nice as well."


Anandtech
"In the end, users purchasing this memory will typically be those looking for any performance advantage and this memory delivers on OCZ’s promise of the highest performing 2x2GB DDR2 memory kit available. While the ability to reach and maintain a stable DDR2-1200 setting was impressive to us, the more impressive aspect of this memory is its ability to run at 4-4-3-10 timings on 1.80V at DDR2-800 or 5-5-4-12 at DDR2-1066 on 1.95V. Really, the greatest strength of this memory is offering a multitude of timings and reasonable voltages up to its DDR2-1200 ceiling in a 4GB package. Pardon the pun, but this memory really is flexible."


Bit-Tech
"The plus sides for the OCZ PC2-9200 Flex II 4GB kit are obvious - it provides not only the new 4GB standard everyone should be aiming to run these days, but also so much overhead even we couldn't get our motherboard to use it all. Currently this is the fastest 4GB kit you can buy. Flex II's independent watercooling channels take the liquid exactly where it is required: right over the memory ICs. If we wanted 4GB of ultra high performance memory to overclock the nuts off our systems - we'd certainly grab the OCZ Flex II PC2-9200 kit, then have a good night out with the wad of cash left over."


CPU3D
"Right from the start, I didn't have any doubts about OCZ's Flex2 DDR2 PC2-9200 4Gb kits ...they performed beautifully, producing some excellent scores in all of our benchmarks. The unique heatsink not only support watercooling through 4 inlets/outlets, but if you opt to go standard air cooling the heatsinks also feature 4 rows of serrated edges to increase the surface area, which help to dissipate the excess heat more efficiently. It's extremely well made and it's one of a kind ... there isn't anything like this on the market as far as I know. If you're an enthusiast who's really mad for watercooling but still using a DDR2 motherboard ... then I would definitely consider the OCZ's Flex2 DDR2 PC2-9200 4Gb kits. It offers good performance with great features, and it's ready for watercooling."


Neoseeker
"The OCZ Flex II DDR2-9200's write performance (stock and overclocked) was outstanding with a fast CPU. The OCZ Flex II DDR2-9200's did very well for bandwidth with at stock, and extremely well when overclocked.These modules were capable of 1200MHz with 5-5-5-14 timing -- which significantly beats the advertised specification of 1150MHz with 5-5-5-18 timing. Unlike many past high performance modules, these modules really were 'plug and play' - and not 'plug and pray'!I was very pleased to see that the Flex II's had absolutely no problem running at their rated speed on a nice X38 board; and the bit of overclocking and latency shaving I managed to do is just icing on the cake."


Legit Reviews
"The OCZ PC2-9200 Flex II 4GB memory kit steps up the game for 4GB memory kits. No longer does 4GB have to be associated with slow and loose timings. Focusing solely at the performance available, this kit really does give you the flexibility to choose between tight timings or high frequencies with appreciable read, write, and copy bandwidth across the board. Factor in the overclocking, Extended Voltage Protection, and the Xtreme Liquid Convection heatsink and you've got a well rounded memory kit. Out of the box the OCZ DDR2 PC2-9200 Flex II 4GB memory kit works great with few adjustments to the BIOS and has great potential for those RAM tweakers out there."


CHIP Magazine (Turkey)
"The OCZ Flex-II we’ve tested is a 4GB DDR2-1150MHz dual memory kit with a top performance. The speciality of these memories are that they can be cooled by a watercooling system. If you have a watercooling setup in your system you can directly connect these memories in your loop. OCZ supplies all accessories in the package, for connecting the memories to your loop."


Oyungezer Magazine (Turkey): Editor's Choice Award
"Among the 4GB DDR2 memory kits OCZ Flex II works at DDR2-1150MHz, which is one of the highest frequencies while the latencies are 5-5-5-18 at rated 2.1V. The full aluminium coolers on the memories are suitable for both air cooling and water cooling. All accessories needed for mounting are included in the package. Without any other converter the memories can be connected to 1/2” and 3/8” hoses in watercooling systems." (Editor's Choice Award, August 2008)


Tech Power Up
"OCZ's package presentation is of the finest quality I've seen yet for a system memory kit. The retail box is quite contemporary. Quite generously, OCZ includes all accessories a watercooler needs to get these modules under water. Included are two adapters that feature a four-way split to route the water to all four faces of RAM (two for each module). The adapter's other end holds either of the included 1/2" or 3/8" barbs included with the kit, depending on the user's setup. OCZ has outdone themselves with the PC2-9200 Flex II 4GB kit. From a great retail presentation to an excellent accessory selection, to great cooling and performance. The kit can indeed run over 1100 MHz at CL5 with just 1.8V and over 1200 MHz with 2.4V"


Egielda (Poland)
“It is truly the best cooling we can imagine and it should clearly be associated with OCZ product. Overclocking is also one of advantages of these memories. They are having the potential unprecedented in other 2x2 kits. How dothey work? Brillant! They don’t fear of high voltage and thanks to superb cooling they are really cold during operation.”


  

Packaging


OCZ's package presentation is of the finest quality I've seen yet for a system memory kit. The retail box is quite contemporary, opening up much like most PC Game boxes, to finely display each module and a schematic explaining OCZ's "Xtreme Liquid Convection" technology.


Once removed from the box, the inner container holds each module, the watercooling accessories, and instruction manual. I was mildly surprised to find that OCZ did not advertise the accessories on the package itself in any way. They are, however, mentioned on the OCZ website.

Quite generously, OCZ includes all accessories a watercooler needs to get these modules under water. Included are two adapters that feature a four-way split to route the water to all four faces of RAM (two for each module). The adapter's other end holds either of the included 1/2" or 3/8" barbs included with the kit, depending on the user's setup.

A Closer Look


The sticker on each module has the model number. There you will also find the info about speed, voltage needed and what the kit is rated for in terms of CL rating.

Installation


With the modules installed, they certainly have a demanding presence. Take special note that with the memory socket layout of the ASUS Maximus Formula, it is not possible to fill the remaining two sockets due to the thickness of the Flex II heatspreaders. This should not be a major issue for anyone however, considering the kit already offers 4 GB total. Additionally, other boards may have a wider memory socket layout that would permit use of the remaining two sockets.

Test Setup

CPU: Intel Core 2 Quad Q6700 G0 Stepping
Motherboard: ASUSRampage Formula X38
Video Card: eVGA 8800 GTS (G92) 512MB Core: 670 MHz Memory: 972MHz
Harddisk: 3 x 320 GB Seagate 7200.10 in RAID 0 Array
Power Supply: Corsair HX1000W
Software: Windows Vista 64-Bit, 177.83 Forceware


CPU-Z was used to check the SPD of the modules. The Part Number reported matches that of the sticker on the heatspreaders which indicates an 1150 MHz rating. OCZ has programmed the memory to 800 MHz at CL5 and 1.8V so that they will boot in any system right away. The advertised settings can then be applied once you enter the BIOS of the system.

Performance

The performance of the kit was tested with separate tests in order to give a well rounded idea of the real world performance buyers can expect. The tests were performed at a range of clock frequencies at each CL: 3, 4 and 5. To test the overclock ability of the kit at each CL, voltages from 1.8V all the way up to 2.4V were employed in order to indicate the required voltage a user can expect to achieve such frequencies.

The results are summarized in the following table and graphs.

While the Flex II kit appears to scale linearly with supplied voltage up to its rated 2.1V, any higher voltage does not seem to help in increasing the maximum overclock of the kit significantly. I should finally note that, while these results are a good indication of expected performance, no two kits will perform identically and that these results are not guaranteed.

Value and Conclusion


  • The OCZ DDR2 PC2-9200 Flex II 4 GB kit sells for as low as $178.00 US Dollars.
  • Runs past rated 1150 MHz at CL5 with even less than the recommended 2.1V
  • Capable of over 1200 MHz at CL5 and 2.4V
  • Roughly half the power consumption of 4 GB (1 GB x4) kits
  • Unique Flex II heatspreaders with the ability to watercool
  • 4 GB to use for newer, more resource hungry games and applications
  • Great retail presentation and accessories kit
  • Runs at 800 MHz at CL4 with as little as 1.8V so buyers should have no problem installing and POSTing without special adjustments
  • Capable of 800 MHz at CL3, however at a toasty 2.4V

 

  • Low maximum overclock at CL4 comparatively
9.0 OCZ has outdone themselves with the PC2-9200 Flex II 4GB kit. From a great retail presentation to an excellent accessory selection, to great cooling and performance. While the issue of the sheer size of these modules heatspreaders is of concern due to blocking the remaining memory sockets on most if not all motherboard layouts, it should only be a serious problem for those users with a motherboard layout that places the dual channel memory sockets directly next to each other rather than staggered.
While the kit can indeed run over 1100 MHz at CL5 with just 1.8V and over 1200 MHz with 2.4V, this also seems to show that the kit has been binned nearly to its limit with just 61MHz of overclocking headroom.
