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:
- 2.4GHz-12x200/DDR400 - the highest stock memory speed supported on VIA 939/nF3-4/SiS755-FX motherboards.
- 2.4GHz-11x218/DDR436 - a ratio near the standard DDR433 speed
- 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.
- 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.
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.

Meh, I am lost for the life of me here. I dont see what the big fuss is over Value VX when I still cant find it. To save the comments http://tinyurl.com/46vg6 this doesnt look like the memory reviewed in the article being 3-4-4-8.Seeing how http://www.newegg.com/app/viewproductdesc.asp?desc... is $87 and I already have some and know it works well... im hard pressed to think I really need to buy "mystery memory".

Finally, is what I can say. However, if you really mean it when say you want to test real life performance, you should test with stuff from the actual standard benchmark suite - Quake 3 might show impressive gains from higher memory bandwidth, but does the same hold true for Doom 3?xsilver: While I agree that testing with the insane voltages available on DFIs limits the scope of the article somewhat, and results for lower voltages would've been nice to see (or at least mentioned specifically, it seems they're actually there for the BH5, though not the VX), I'm frankly more annoyed with all the other motherboard manufacturers for not allowing higher voltages (Abit in particular), than I am with AT for going ahead and testing with the only one that does. I wouldn't call it advertisement, more like a fair appraisal of capabilities.

I thought it was interesting to see in the charts that the Crucial Balistix which are $204 right now ($106 each but 4% off if you buy two and therefore JUST missed the price cutoff for this review) were consistently very good (faster than almost everything in this review) and are the only ones that can be that fast on more normal (non-DFI) voltages.xsilver - Tuesday, April 12, 2005 - link
Im not saying the dfi is bad or expensive.... its just that if you review with features that only the dfi can provide its not really a review / roundup anymore ..... its called an advertisment.... where's the choice?????I expect that dfi shareholders to be laughing really loud right now.... and OCZ too....

Value VX is $115 if you shop around, how does this count it out of a value roundup?Should AT have only reviewed value ram that performs poorly?

#40 actually alot people would do just that.The DFI mother is not really that expensive.
Asus and gigabit are the the same price. 6800GT cards are high but if you want the best cards you buy them, to play the games. But how many times have anyone said what type of ram you need to play Doom 3 or HL. No one. If you don't over clock, then $90 ram will slow you system down what 1-2% over $300 ram. I got a A64 3400 and 800XL and kingmax ram. And my system runs alot fat then my friend with with a just 800 and $250 ram.
Sorry but buying high priced ram are mostly for over clockers and most people don't do that. Alot on these tech sites do, but my guess is even most people that buy $200+ ram don't
The review was nice to me.
xsilver - Tuesday, April 12, 2005 - link
another thing I want to clarify is that you make the assumption that you must be a "mad overclocker" if you buy the dfi because it can do 3.4v and all others that dont have the dfi are just posers..... many people would disagree but you seem to not notice???xsilver - Tuesday, April 12, 2005 - link
wesleyI understand what you say about making things consistent but arent then you just promoting the dfi board as no other board supports 3.4v? what about people who are going nforce 3 or intel (god forbid :P)
in trying to maximize the potential of the ram, you are limiting the practical application...
an analogy would be "in testing a ferrari its performance is great when drive it with brand X of fuel and feed it liquid oxygen".... umm... what about the rest of the people that dont use that?... that's why car reviews talk more about the "feel" & handling of the car, things that can be appriecieated by ALL customers....
and by specifying that this review was more for "mad overclockers" that may use the dfi then why even review the cheaper solutions that dont even overclock at all... I mean its not exactly fair when you compare the really cheap ram to some OCZ VX values now is it?
On one hand you try and generalize to the broader market but then on the other you say that you're only catering to the "mad overclockers" that buy the dfi
your original scientific basis / aim is a little unsound

If your looking for value VX look here.http://www.atacom.com/program/print_html_new.cgi?c...
http://www.newegg.com/app/ViewProductDesc.asp?desc...
Look closely at the part number is has WV which stands for with winbond die, timings are usually 3-4-4-8 or 2.5-3-3-8 buit its all the same stuff.

Where exactly can you find the Value VX? Do you have a model number? I was going to buy the Corsair Value RAM, but after reading this, I definitely think I'm going OCZ.
