OCZ PC2-9200 Flex XLC Memory Review - Passive and Liquid Cooled

Results and Conclusions

Overclocking Results

For testing the overclocking capabilities of our OCZ Technology Flex XLC modules, we used the identical setup that we used in our recent Corsair Dominator review.  I ran the tests on an EVGA 680i motherboard using an Intel Core 2 Extreme X6800 processor and the model of the Flex XLC we used were the top-speed PC2-9200 modules rated at 1150 MHz at 5-5-5-18 timings. 

I was able to achieve the same 1200 MHz mark with the OCZ Flex XLC modules very easily:

In fact, I was able to reach 1280 MHZ without a hassle at all -- without a doubt these modules are going to overclock at or beyond any other memory on the market!  All of this testing was done with passive cooling, just to make the results typical of most of our readers. 

Editor's Note: I have had several people contact me about the overclocking results here, and wanted clarification as to why the OCZ Flex XLC modules overclocked further than Corsair's Dominator modules, even on passive cooling.  The answer is: they didn't.  In my tests here, I was not looking to find the "maximum FSB overclock" with either modules in these articles.  Rather, I was trying to see if the DIMMs could overclock "well."  In my opinion, showing you a graph of 10 different DIMMs all overclocking to with 15 MHz of each other is POINTLESS at best and LYING at worst.  There are so many factors involved in maximum threshold overclocking, including even individual DIMMs from the same series, that me trying to tell you WHICH one overclocks the most seems just ridiculous.  However, I can say with confidence that BOTH the OCZ Flex XLC and the Corsair Dominator modules I tested overclocked WELL. 

Cooling Results

I was very curious to see how much the water cooling option actually helped the temperatures on the modules.  As seen on the previous page, we tested the primary module both with and without liquid cooling running on my standard Koolance Exos external cooling units.  The Corsair modules were also tested with and without their Dominator Airflow fans for a comparison. 

The SiSoft Sandra memory burn-in test was run for an hour while taking temperature measurements. 

First, note that the passive cooling results from both the OCZ Flex XLC and Corsair Dominator modules are very good and comparable.  The additional cooling options for both show a marked improvement in temperatures; Corsair's Airflow drops the temperature by a full 10 degrees Celcius while the OCZ Flex XLC modules see a huge 17 degree temperature drop!

The results speak for themselves: OCZ's Flex XLC modules provide the coolest memory we have ever seen with teamed with a water cooling setup and provide those impressive results while remaining silent!

Available Kits

As of this writing, there are three seperate kits that use the OCZ Flex XLC memory cooling technology:

Part Number Speed Latency
OCZ DDR2 PC2-9200 FlexXLC 2GB (2x1GB) 1150 MHz 5-5-5-18
OCZ DDR2 PC2-6400 CL3 FlexXLC 2GB (2x1GB) 800 MHz 3-4-4-15
OCZ DDR2 PC2-6400 CL4 FlexXLC 2GB (2x1GB) 800 MHz 4-4-4-15

There isn't a whole lot of variety here in what Flex XLC offerings OCZ Technology has, but I think the most popular will definitely be the 1150 MHz rated PC2-9200 modules.

Pricing and Availability

This memory technology does have one weakness: price!

Part Number Pricegrabber Price @ Newegg
OCZ DDR2 PC2-9200 FlexXLC 2GB (2x1GB)



OCZ DDR2 PC2-6400 CL3 FlexXLC 2GB (2x1GB)



OCZ DDR2 PC2-6400 CL4 FlexXLC 2GB (2x1GB)



I was unable to find any of the CL3 latency DDR2-800 Flex XLC memory for sale as of this writing, but I am sure it will show up back in stock somewhere soon.  Just check our pricing engine often

Compared to the pricing of the Dominator memory, the OCZ Flex XLC is just slightly below similarly spec'd Corsair modules.  Of course, Corsair doesn't offer the water cooling option that OCZ Technology does with these modules, so the lower price is actually noteworthy.  Don't get me wrong here; $400+ for memory is a high cost for an ethusiast to drop but if you are looking for high performance, high bling memory this is the place to look!

Final Thoughts

If you are in the market for the ultimate enthusiast memory solution, OCZ Technology's Flex XLC modules fit that bill perfectly.  Offering not only superb passive cooling, the XLC cooling solution can supply even lower memory temperatures with the option for liquid cooling.  OCZ's latest offering for the enthusiast really impresses!

If you have any questions or comments on this product or my review, please head into this thread in our forums to discuss it!  I'll try to answer anything that pops up in there.
