Performance Test Configuration

All seven Value RAM memories were tested on the DFI LANParty nF4 SLI-DR used in our most recent memory reviews. nForce4 is PCI Express, so we used the PCIe version of our standard nVidia 6800 Ultra for testing. Other components remain the same as used in the memory setup in Athlon 64 Memory: Rewriting the Rules. Performance was compared to the 5 top performing memories tested on this same platform in OCZ VX Revisited: DDR Updates on DFI nForce4 and Patriot DDR400 2-2-2/DDR533 3-4-4: Performance AND Value.

The A64 test bed includes components that have been proven in Socket 939 Athlon 64 benchmarking, such as the Socket 939 4000+ (same specifications as FX53), and the OCZ Power Stream 520 Power Supply. Since the Athlon 64 tests represent a new series of DDR testing, we are using the current generation nVidia 6800 Ultra video card for benchmarking. We have found the 6800 Ultra to be a particularly good performance match to nVidia 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.

In past benchmarking, we have found performance of the nForce4 and nForce3 chipsets to be virtually identical, and we have found AGP and PCIe performance to be virtually the same in the benchmarks that we use for memory testing. Therefore, you can also compare these results to TCCD benchmarks in recent memory reviews. The differences in results are that the nVidia 71.84 driver is a bit faster than the 61.77 used in earlier memory review. The DFI nForce4 platform is also a bit better at memory overclocking than the MSI K8N Neo2 used in past memory testing. The performance differences, however, are not large enough to negate performance comparisons.

With nForce3 motherboards, we achieved the fastest performance on AMD Athlon 64 chipsets (nForce3, VIA K8T800 PRO) at Cycle Time or tRAS of 10. However, the nForce4 appears to behave a bit differently with memory. Therefore, we ran a complete set of Memtest86 benchmarks with only tRAS varied to determine the best tRAS setting for these memories. We achieved the best bandwidth at tRAS settings ranging from 5 to 8, so a tRAS setting of 6 was used for testing wherever possible.

Test Settings

All AMD Athlon 64 processors are unlocked downward, and the FX CPUs are unlocked up and down. This feature allows 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 4000+/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, removing CPU speed as a factor in memory performance.

The following settings were tested with the seven Value RAM memories on the DFI nF4 test bed:
  1. 2.4GHz-12x200/DDR400 - the highest stock memory speed supported on VIA 939/nF3-4/SiS755-FX motherboards.
  2. 2.4GHz-11x218/DDR436 - a ratio near the standard DDR433 speed
  3. 2.4GHz-10x240/DDR480 - a ratio near the standard rating of DDR466. Several of the Value Memories achieved stable performance at this speed and complete benchmarks were run at this speed with those memories.
  4. Highest Memory Performance - the highest memory bandwidth and game performance that we could achieve with the memory being tested. This is rarely the highest memory speed that we could achieve. It is normally a lower speed with 1T Command Rate and tighter memory timings.
Command Rate is not normally a factor in Intel DDR tests, but it is a major concern in Athlon 64 performance. A Command Rate of 1T is considerably faster on Athlon 64 than a 2T Command Rate. For this reason, all testing was at 1T Command Rate. Command Rate and voltage are reported for each memory speed setting.

We ran our standard suite of memory performance benchmarks - Quake 3, Return to Castle Wolfenstein-Enemy Territory-Radar, Super Pi 2M, and Sandra 2004 Standard and UnBuffered. We also included Everest Home Edition memory tests, free at www.lavalys.com, for read speed, write speed, and Latency.

    1 GB (2 x 512 MB) of Crucial Ballistix PC 3200 now lists for $192 U.S. at crucial.com.

    On any mobo, it runs at 200 MHz (DDR 400) at 2-2-2-6 timings at 2.8 V, outperforming any other RAM in this review.

    As shown by AnandTech (www.anandtech.com/memory/showdoc.aspx?i=2386), on a DFI nF4 mobo, it overclocks to 280 MHz (DDR 560) at 2.5-3-3-6 timings at only 2.9 V, where it closely matches the top performance of any RAM available at any price, bar none. IMHO, this is real value.

    Adding a Venice 3200+ overclocked to 10 x 280 MHz = 2.80 GHz (www.xbitlabs.com/articles/cpu/display/athlon64-venice.html), a Thermalright XP-90 heatsink with a SilenX 92mm 14dBA fan, a Seagate 7200.8 SATA NCQ hard drive, and a Gigabyte X800 XL video card with SilentPipe cooling (GV-RX80L256V), in an Antec Performance One (P160) case (www.anandtech.com/casecooling/showdoc.aspx?i=2346) with an XG Magnum 500W heatpipe PSU (available later this month, according to www.xgbox.com), you have the makings of an ultra-quiet gaming rig with near state-of-the-art performance at a great bang-for-the-buck price.

    you can. i'm a big advocate of crucial ballistix

    speaking of that company, why were they missing from the testing too?
  • BaronVonAwesome - Thursday, April 14, 2005 - link

    195 seems a bit steep for value RAM. I'd like to point out that you can get Ballistix from Crucial for less than 210 I believe.

    Thanks for pointing out that the part numbers are on page two. As many others have said, it would have been really nice to see the best the different rams would do at 2.9v in addition to what they would do with DFI voltage. Also it would have been nice to see a greater range of memory tested but I understand you are limited by not being able to afford to buy and test what you want. Beggars can't be choosy. Thanks for doing this though, the general concept was good and there was some interesting information.

    Paying $100 to buy some Corsair Valueram (Newegg--had an $88 special yesterday) would have been the fair and reasonable course of action.

    Consumer Reports has been testing products fairly for decades--they don't accept advertising, and, they buy the cars, electronics, and other items they test anonymously. Of note is that "Sharper Image" has sued them recently (SI lost) when they tested one of their bogus "air purifiers"--seems to make the air less clean, actually, by releasing ozone.

    Anandtech should get some Corsair RAM and test it--and, they should buy samples of the other brands tested, and compare the "off the street" samples with the ones provided by the manufacturers. Unless I am mistaken, video card makers were found to be rigging their drivers to test better with certain benchmarks. It would not be too surprising to find that memory manufacturers had taken some of their special high cost "binned" chips and sent them out with a "value" label on them.

    Oh dear ... I left this review for 2 days till I had time to read it properly, I'm sorry to say I wish I had not bothered.

    1) Should have been titled value ram from non value companies. Wheres the real value ram?

    Since the price began to drop we seem to be up to our ears in stuff ive never heard of purporting to be cas3@3200 - Stupid me for thinking that thats what a value roundup should include, noname oem kit, not some hand selected bunch of good-but-value-priced ram from the majors.

    2) Why is the following question being avoided and ignored? Namely why wasnt any corsair memory got from another source and included in the test?

    A reader posted some assumptions however further to that it could be i) they use pretty much the same chips all over and dont want to give the game away that the extra $100 doesnt get you much increase and ii) anandtech dont want to bite the hand that feeds so bowed down to the request rather than doing whats right and finding the truth come hell or high water.

    Im not usually this negative but I do feel quite let down, sorry.

    I think a lot of folks are missing it. I think some people need to look at this way. You would have upgrade your cpu 1-2 speed grades to equal the performance increase that using the VX or BH5 memory would bring. Even at stock speeds. Now yes you need more voltage, but DFI I believe produces the best A64 borads as well as the best athlon XP board, Ultra B, which all are capable of supplying the necessary voltage. You can also use the ddr booster on some boards. Its a great alternative to increase system performance without spending a lot of money. And this is memory that you can grow with for at least a couple of years. I believe AMD said it won't go DDR2 until 2007. Great article, good stuff, and nice to see other ways to bring a performance increase. Nice job Wesley

    The cheap OCZ is faster then the Plat. Rev2 !!! Ain't dat a Bitch!!! >:-(
    WTF is up with OCZ. shooot.
  • srstudios - Wednesday, April 13, 2005 - link

    Wesley, I hate to be a nag, but now you have both the OCZ PC3200 Gold, and the OCZ PC3200 Premier with the same model number. PC3200 Gold P/NOCZ4001024ELDCGE-K
    is correct.

    The Premier should be PN- OCZ4001024PDC-K, at least I think that's the correct part. http://www.ocztechnology.com/products/memory/ocz_d...

    I have a gig of the 'old' BH-5, Mushkin Black L2 PC3500, do you think they would play nice with this new value BH-5? I don't think I would combine them, just wonder if you guys have any thoughts about it.
