OCZ DDR3-1600 Platinum vs. Patriot DDR3-1866 Viper

 

Both of these products were used in our recent review of the ASUS P5E3 Premium motherboard. We saw some rather interesting phenomena with both of these memory kits in that review so we have decided to review both of these kits comparatively in much more detail using the same test rig. Our goal is not only to give you a complete review of these two memory products, but to also answer the questions we alluded to in the beginning of this introduction.

INTRODUCTION

One of the pressing questions on many of the computer enthusiast forums today is: “How much memory should I buy for optimal performance on my rig?” To answer this question properly we need to take into account a few variables such as: 1) Whether the consumer is using a 64bit or 32bit OS; 2) The speed of their CPU and mother board coupled with the memory speed to be used; and 3) Just what is meant by optimal performance? We have read some articles by excellent authors that attempted to detail in highly technical terms their findings with regard to this looming question. In many cases the degree of the information presented was beyond the realm of comprehension by those not having a strong electronics background.

Recently we received two DDR3 kits, one from OCZ Technology and one from Patriot Memory. The kit from OCZ was their 4GB DDR3 12800 (DDR3 1600) Platinum Enhance Bandwidth product and Patriot sent us their 2GB Viper DDR3 15000 (DDR3 1866) kit. Both of these products were used in our recent review of the ASUS P5E3 Premium motherboard. We saw some rather interesting phenomena with both of these memory kits in that review so we have decided to review both of these kits comparatively in much more detail using the same test rig. Our goal is not only to give you a complete review of these two memory products, but to also answer the questions we alluded to in the beginning of this introduction.

With the OCZ 4GB kit we see the familiar platinum heat spreader that we have grown to know over the years. The Platinum series of memory has been in existence since heat spreaders for memory modules first became popular shortly after the initial launch of DDR (Yes, DDR1). Even though OCZ has many other memory kits, the Platinum series has always been synonymous with both quality and performance.

Patriot 2GB DDR3-15000 Viper Kit … Timing

The Viper series of memory modules has a relatively new styling for Patriot. The primary difference are the aluminum finger-like projections at the top of each heat spreader. As with any passive cooling solution these projections are set to dissipate heat by channeling it upward into each finger where air flowing through your system’s enclosure can continuously carry the heat away from each memory module.

TESTING REGIME & METHODOLOGY

Prior to performing any benchmarking we always run MemTest 386 for a minimum of 10 complete cycles to ascertain that the memory product is completely error free prior to proceeding. Next, we allow the memory to run in the system for a few days in activities ranging from surfing the WEB to intensive gaming sessions, in other words my general day to day activities. I view this as a break-in period for the memory product. While many of my peers feel this break-in time is no longer necessary with modern day RAM; I feel it allows me to get a feel for what the memory being tested is capable of, and old, deeply engrained habits die hard.

As previously stated, we’re running Vista 64 Ultimate, an operating system that will take full advantage of 4GB of memory. Our goal is to determine whether the 4GB OCZ DDR3-12800 Platinum kit, with lower latencies and double the size, will perform in the same league as the Patriot 2GB DDR3-15000 kit which should run faster at maximum settings. We intend to test each of these products at all popular DDR3 memory frequencies running the lowest timings possible to achieve the results. We also plan to overclock each of the kits to ascertain just how much headroom each product brings to the table. To do so we plan the use the synthetic benchmarks and game captioned in the table below.

MEMORY MODULE SPD

As computer enthusiasts most of us have learned not to pay any attention to the SPD settings of the memory that we utilize. This is do in no small part to the fact that most memory will run quite well at somewhat lower timings than expressed in the SPD, and is generally rated lower by the manufacturer. We, however, still feel it incumbent upon us to present this data and you may take it with whatever degree of importance that you wish.

We’d like to present another very interesting tidbit of information before we show you our test results. The Patriot 2GB DDR3-15000 Viper Kit defaults at all memory frequencies to a command rate of 1T with the command rate control left on auto. We were unable to force the OCZ 4GB DDR3-12800 Platinum Kit to run at 1T at any of the memory frequency settings. As it turned out this made little difference in the outcome of the testing, but is still a fact that you should be aware of.

SANDRA PROFESSIONAL

“SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what’s really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCI-X, PCIe (PCI Express), database, USB, USB2, 1394/Firewire, etc.”

 

 

SUPERPi

SuperPi is the “Gold standard” for many when it comes to judging system performance. We ran 1 and 2 Meg calculations again running each test three times and reporting the average of the results.

Super Pi is used by most computer enthusiasts to test the performance and stability of their computers. In the overclocking community, it provides a benchmark for enthusiasts to compare “world record” pi calculation times and demonstrate their overclocking abilities. The program can also be used to test the stability of a certain overclock speed. If a computer is able to calculate PI to the 32 millionth place after the decimal without mistake, it is considered to be moderately stable in terms of RAM and CPU. However, longer tests with other CPU/RAM intensive calculation programs will run for hours instead of minutes and may better stress system stability.

F.E.A.R v. 1.08

F.E.A.R. (First Encounter Assault Recon) is a first-person shooter game developed by Monolith Productions and released in October, 2005 for Windows. F.E.A.R. is one of the most resource intensive games in the FPS genre of games ever to be released. The game contains an integrated performance test that can be run to determine your system’s performance based on the graphical options you have chosen. The beauty of the performance test is that it gives maximum, average, and minimum frames per second rates and also the percentage of each of those categorical rates your system performed. F.E.A.R. rocks both as a game and as a benchmark!

 

CRYSIS v. 1.2

Crysis is the most highly anticipated game to hit the market in the last several years. Crysis is based on the CryENGINE™ 2 developed by Crytek. The CryENGINE™ 2 offers real time editing, bump mapping, dynamic lights, network system, integrated physics system, shaders, shadows and a dynamic music system just to name a few of the state of-the-art features that are incorporated into Crysis. As one might expect with this number of features the game is extremely demanding of system resources, especially the GPU. We expect Crysis to be a primary gaming benchmark for many years to come.

 

A WORD ON OVERCLOCKING

As the results of this initial phase of testing show we were able to push the OCZ to a maximum overclock of DDR3 1684 MHz. Even though we could get this kit to boot into Vista 64 at at frequencies up to 1800 MHz all attempts to make it stable at any frequency higher than 1684 MHz failed. We spent almost two hours trying every trick we know but a higher clock was not to be had. This 4GB kit differs greatly from results we have witnessed on other review sites where its 2GB counterpart was able to reach a stable frequency of 2 Ghz. We’ve always heard that no 4GB memory kit would run as fast as an exact 2GB twin, and I guess this proves it. At least we were able to get an overclock with the OCZ product, the Patriot 2GB DDR3-15000 Viper Kit was completely stable at 1864 MHz would not boot at a frequency over 1900 MHz.

WAIT! Before judging either of these kits too harshly because of our statements in the previous paragraph please read on. We alluded to some weird phenomena in the introduction and now it’s time to spill the beans. We are testing this memory with a new Intel® X3350 Xenon Core 2 Quad 45nm processor that is said to be the twin of the just released Q9450. In our review of the ASUS P5E3 Premium motherboard we also used this processor and both of these memory kits. We experienced some idiosyncrasies with the processor especially when it came to booting at a high FSB (>480 MHz) when using a multiplier lower than 7.5. To prove this we dropped our Core 2 Duo E6850 in this system and were able to reach 1800 MHz with the OCZ 4GB DDR3-12800 Platinum Kit and just over 2GHz with the Patriot 2GB DDR3-15000 Viper Kit. The test results were significantly slower using this processor; as much as 2 seconds slower running SuperPi and up to 1,000 MB/sec slower running the synthetic benchmarks. Talk about an conundrum! Is the issue with the processor or the motherboard? Or a combination of the two. At present we can’t answer that question, but fully intend to keep testing until we can.

REAL WORLD TESTS

While doing some research for this review and preparing to do a fresh install of Vista 64 with the recently released SP1, we had an epiphany. We felt as though we should see some level of speed increase installing each of these products using 4GB of DDR3 as opposed to 2GB. To eliminate any bias we ran both sets of memory at a frequency 1333 MHz and the processor at stock speed of 2.66 GHz. All other controls in the motherboard’s BIOS were set to auto. If our hypothesis is correct we should see some improvement in the speed of these two operations. We measured the speed using an electronic stopwatch which was started and stopped manually at as close to the same point as humanly possible. Our results follow in the table below:

FINAL WORDS & CONCLUSION

This has been a very informative review for the Bjorn3D staff as several of us played a role in interpreting the results ascertained from reviewing these two fine memory products. The OCZ 4GB DDR3-12800 Platinum Kit has a slight upper hand in memory intensive tasks, especially when using a 64 bit operating system such as Vista 64 than can fully utilize the additional memory. If you’re looking for sheer speed then the Patriot 2GB DDR3-15000 Viper Kit takes a leading role when using memory frequencies in excess 1684 MHz. Below the 1680 MHz mark where the both products are tested in a mano-a-mano fashion in the synthetic benchmarks the OCZ Platinum Kit has a slight edge in all tests with the exception of the 2 Meg calculations in SuperPi. In gaming there are generally only 1 or 2 FPS separating the two products.

As far as value is concerned the OCZ 4GB Platinum kit gets the winning nod as it is priced very reasonably in the $400 – $420 USD range as opposed to the Patriot 2GB Viper kit which tips the cash register in the $260 – $280 USD range. There is, however, currently a $25 rebate on the Patriot Viper memory lessening the margin a bit. If you’ve checked the current pricing on most high-end DDR3 kits recently you’ll see that both of these kits are reasonably inexpensive.

We at Bjorn3D have always believed it prudent to buy as much memory as you can afford as long as there isn’t a huge difference in performance. We saw the benefit of 4GB vs 2GB in our real world tests even though the test’s methodology might have some room for question as with any new benchmark. For the average user that isn’t into extremely memory intensive apps, the 2GB Patriot Viper DDR3-15000 kit is certainly more than adequate.

When it comes to recommending these two fine DDR3 memory kits we’ve already stated a case for each one. Due to the issue we described in the review with the processor and/or motherboard we will score these two products equally when it comes to overclocking and will not list it as either a strength or weakness. We feel both of these kits are quite capable of overclocking quite well given the proper set of components. When it comes to scoring the two products they are almost equal with the OCZ 4GB DDR3-12800 Platinum, receiving a slighter higher score due to better performance when compared equally with the Patriot 2GB DDR3-15000 Viper Kit. Neither of these products are what you might consider a slouch; both, depending on your needs, are certainly worthy of consideration.
