OCZ 3700 Gold Rev. 3: DDR500 Value for Athlon 64 & Intel 478
by Wesley Fink on September 22, 2004 12:05 AM EST- Posted in
- Memory
Several weeks ago, OCZ introduced a new PC4000 Gold Rev. 2. The new revision was very interesting, since it carried the high performance Gold name, but was priced about 25% lower than other OCZ DDR500 memory. It was our plan to review the DDR500 to see how it compared.
As we completed testing of OCZ 4000 Gold Rev. 2, we were told by OCZ that yields were so good with the new Hynix memory chips, they had decided to use the same memory chips in their new 3700 Gold Rev. 3. This means that the current 3700 Gold Rev. 3 and the 4000 Gold Rev. 2 are the exact same DIMMs for the time being. This could always change in the future, if yields do not maintain the same high levels that OCZ is currently seeing, but for now, you can buy 3700 Gold Rev. 3 and be assured that you are receiving memory which has been binned for DDR500 performance. This certainly makes the 3700 Gold Rev. 3 a particularly good buy right now.
While the price of the OCZ PC3700 Gold Rev. 3/PC4000 Gold Rev. 2 appears a good value, the proof of value is in how the 3700/4000 performs compares to similarly rated memory. We have run the new Rev. 3 through our full benchmark suite on the standard Intel 875 memory test bed. We also ran the first complete series of memory tests on a new Athlon 64 memory test bed. So, how does the OCZ 700 Gold Rev. 3 compare?
OCZ 3700 Gold Rev. 3
OCZ produces a complete line of memory from value-priced memory to some of the fastest enthusiast memory that we have tested. While their memory products may be the best known to most, they also produce heatsink/fans, thermal compound, the recently introduced power supply line, and an innovative DDR voltage booster.3700 Gold has been a very well-known memory product for OCZ, as you can see in our earlier reviews of the original 3700 Gold and 3700 Gold Rev 2. The first two generations of 3700 Gold earned quite a reputation for outstanding overclocked performance, but they were also premium-priced DIMMs. This latest Revision 3 is the first 3700 Gold to be marketed by OCZ as a value DIMM.
Test DIMMs were a pair of OCZ 3700 Gold Rev. 3 in a 1GB kit (2x512MB modules). PC3700 Gold Rev. 3 is available as a 512MB kit (2x256MB DIMMs), a 1GB kit (2x512MB), and as individual 256MB and 512MB DIMMs. The 3700 Gold Rev. 3 is shipped in the new Orange OCZ package.
OCZ uses trademark gold colored heat spreaders on the 3700 Gold, which should not come as a surprise to anybody. SPD timings are specified on the label. OCZ tells us that the memory chips for 3700 Gold Rev. 3 are manufactured by Hynix. A quick check showed the Hynix chips to be the recent DT-D5 chips.
OCZ 3700 Gold Rev 3 Specifications
OCZ 3700 Gold Rev. 3 Memory Specifications | |
Number of DIMMs & Banks | 2 DS |
DIMM Size Total Memory |
512 Mb 1 GB |
Rated Timings | 2.5-3-3-8 at DDR466 |
SPD (Auto) Timings | 2.5-3-3-8 |
Rated Voltage | 2.8V (3.15V Maximum) |
Voltage is specified as 2.8V at the rated DDR466. We found that much voltage worked fine at lower memory speeds. OCZ specifies the highest recommended voltage as 3.15V, which certainly allows for even higher overclocking on the few boards that support this memory voltage. This also provides some headroom if you choose to use the OCZ DDR Booster.
Intel Performance Test Configuration
We tested the OCZ 3700 Gold Rev. 3 in our standard Intel Pentium 4 Memory test bed. The hardware for evaluating the Ultra X memory is the same used in our earlier reviews of DDR400 and faster Memory.All test conditions were as close as possible to those used in our earlier memory reviews. We have also eliminated from our charts any memory that has been discontinued, including Winbond BH5 and BH6 versions from several vendors and earlier versions of several current memory products.

We have found the fastest performance on Intel 865/875 to be achieved at Cycle Time or tRAS of 5, or the fastest tRAS setting that is stable with the tested memory. Intel platform benchmarks were therefore run with the fastest stable tRAS timings that we could achieve with the Geil Ultra X.
Test Settings
We ran our standard suite of memory performance benchmarks. The following settings were tested with the OCZ 3700 Gold Rev. 3 memories:- 800FSB/DDR400 - the highest stock speed supported on 875/865 and K8T800/nF3/SiS755 motherboards.
- 866FSB/DDR433 - a speed rating that we have used in testing other low-latency DDR400 memory.
- 933FSB/DDR466 - the rated speed of OCZ 3700 Gold Rev. 3.
- 1000FSB/DDR500 - a standard memory speed used in testing other high-speed memory and the rated speed of OCZ PC4000 Gold Rev. 2.
- 1066FSB/DDR533 - a standard memory speed included for comparison.
- Highest Stable Overclock - the highest settings we could achieve with this memory and other memory that we have tested.
Intel Test Results: OCZ PC3700 Gold Rev. 3
To be considered stable for test purposes, Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and Comanche 4 had to complete without incident. Any of these, and in particular Super PI, will crash a less than stable memory configuration. We have also included results for RCW-ET using the Radar benchmark.OCZ 3700 Gold Rev. 3 (DDR466) - 2 x 512Mb Double-Bank | ||||||

OCZ 3700 Gold Rev. 3 is a bit slower at DDR400 than the top-performing 2-2-2 DIMMs based on Samsung and Micron chips. However, performance at DDR400 is still reasonably competitive with 2-2-2 timings. In the range from 450 to 533, the 3700 Gold R3/4000 Gold R2 are very competitive, performing as well as the top DIMMs that we have tested in that memory speed range.

Searching for the Memory Holy Grail - Part 2
Memory performance was compared at DDR400, DDR433, DDR466, DDR500, DDR533 (where possible), and the highest stable overclock we could achieve that would run Quake 3, UT2003, and Super PI to 2MM places.
All discontinued products have been removed from benchmark comparisons.
Results are compared for Quake 3, Sandra UNBufferred Memory Test, and Super PI. SiSoft Sandra 2004 reports 2 results for each memory test - an Integer value and a Float value. Results reported in our charts are the result of averaging the INT and FLOAT scores, which are normally close in value. In other words, INT and FLOAT scores were added and divided by 2 for our reported score.

AMD Performance Test Configuration
This memory test is the first benchmarking on the new Athlon 64 memory test bed. Since we have found DDR memory to perform very differently on the memory controller with Athlon 64 chips, we will be including Athlon 64 benchmarks in all future memory reviews.The A64 test bed includes components that have been proven in Socket 939 Athlon 64 benchmarking, such as the Gold Editors Choice MSI K8N Neo2, the completely unlocked Socket 939 FX53, and the OCZ Power Stream 520 Power Supply. Since the Athlon 64 tests represent a new series of DDR testing, we have chosen the current generation nVidia 6800 Ultra video card for benchmarking. We have found the 6800 Ultra to be a particularly good match to nVidia nForce3 Ultra motherboards.
All other basic test conditions attempted to mirror those used in our earlier Intel memory reviews. However, test results are not directly comparable to tests performed on the Intel test bed.
AMD nForce3 Ultra Performance Test Configuration | |
Processor(s): | AMD FX53 Athlon 64 (2.4GHz, Socket 939, Dual Channel, 1000HT) |
RAM: | 2 x 512MB OCZ PC3700 Gold Rev. 3 (DS) |
Hard Drives | Seagate 120GB PATA (IDE) 7200RPM 8MB Cache |

Video Drivers: | nVidia Forceware 61.77 |
Power Supply: | OCZ Power Stream 520W |
Operating System(s): | Windows XP Professional SP1 |
Motherboards: | MSI K8N Neo2 |
We have found the fastest performance on AMD Athlon 64 chipsets (nForce3, VIA K8T800 PRO) to be achieved at Cycle Time or tRAS of 10. Athlon 64 platform benchmarks were therefore run with the tRAS timing of 10 for all A64 benchmarks.
Test Settings
The FX53 is completely unlocked, something not currently available with Intel processors. This allowed a different approach to memory testing which truly measures performance differences in memory speed alone. All tests were run with CPU speed as close to the specified 2.4GHz of the FX53 as possible, with CPU speed/Memory Speed increased at lower multipliers to achieve 2.4Ghz. This approach allows the true measurement of the impact of higher memory speed and timings on performance, since CPU speed is fixed.The following settings were tested with the OCZ 3700 Gold Rev 3 on Athlon 64:
- 12x200/DDR400 - the highest stock memory speed supported on 875/865 and K8T800/nF3/SiS755 motherboards
- 11x218/DDR436 - a ratio near the standard DDR533 speed
- 10x240/DDR480 - a memory speed near the rating of OCZ 3700 Gold Rev 3
- 9x267/DDR533 - a standard memory speed used in testing other high-speed memory
- 8x300/DDR600 - a standard for future memory speed testing. Few if any current memories will reach this speed
- Highest Stable Overclock - the highest settings we could achieve with this memory and other memory we have tested
AMD Test Results: OCZ PC3700 Gold Rev. 3
To be considered stable for test purposes Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and RTCW had to complete without incident. ANY of these, and in particular Super PI and Return to Castle Wolfenstein, will crash a less-than stable memory configuration.OCZ 3700 Gold Rev. 3 (DDR466) - 2 x 512Mb Double-Bank | |||||||

*During testing, we discovered that while half-ratios do reflect CPU settings accurately, they are not really linear for memory speed. Memory speeds at full ratios are reported accurately. The asterisk values are the actual memory speeds at half ratios - not the reported memory speeds. Special thanks to Oskar Wu of DFI for his help in determining true half ratio memory speeds.
We have become accustomed to memory often reaching much lower overclocks on Athlon 64 than what we have found on the Intel 478 platform. It was, therefore, a pleasant surprise to find the OCZ 3700 Gold Rev. 3 actually performing slightly faster on the Athlon 64 Dual Channel 939 board than what we found on the Intel platform. OCZ claims that the 3700 Gold Rev. 3 performs equally well on A64 and Northwood/Prescott, and we were certainly able to confirm that claim in our memory tests.
Final Words
OCZ PC3700 Gold Rev. 3 brings some real value to the high-speed arena. On the Intel DDR 478 boards, there are faster 2-2-2 memories from most vendors at DDR400, but the 3700 Gold R3 is still competitive with the fastest memories that you can buy. In the range from DDR450 to DDR533 - the primary operating range of PC3700 Gold Rev. 3 - the new R3 competes well with anything else that we have tested. Overall, the 3700 Gold R3 brings very good value to those using Intel processors on an Intel 865/875 chipset. The Rev. 3 is a decent value on the Intel platform, and the performance is competitive, but it is not a standout memory unless you take price into consideration.Where 3700 Gold Rev. 3 stands out is the Athlon 64 Dual-Channel platform. Many recent memories that have performed quite well on Intel boards have done much poorer on the dual-channel A64. We were very pleased to see that the R3 matched the Intel performance on our new Athlon 64 test bed. In fact, it actually went a bit higher on the MSI K8N Neo2 compared to what it achieved on the excellent Asus P4C800-E. Athlon 64 shoppers looking for a more reasonably priced high speed memory for Socket 939 Athlon 64 boards will find the 3700 Gold Rev. 3 to be a very good choice. On this platform, the value is extremely good.
While the new Rev. 3 is not the standout performer of the earlier Rev. 2 that it replaces, the memory does perform well over a very wide range of memory speeds. It is also one of the few memories to deliver 2.5-3-3 timings at DDR500 at a reasonable voltage. You will like the OCZ 3700 Gold Rev. 3 on your Intel motherboard.
On an AMD Athlon 64, you will absolutely love this memory. It is a standout performer on Socket 939 Athlon 64 at a price that is much easier to handle than some other memory that has performed well on Athlon 64. Athlon 64 shoppers in particular would do well to add OCZ 3700 Gold Rev. 3 to their memory shopping list.
