Value RAM Roundup: Computing On a Budget

OCZ PC3200 Gold: "Value BH5"
When OCZ submitted three different memories for this Value RAM roundup, we first thought it was overkill and an attempt to hijack the roundup. However, as we looked closer at the three memories and the benchmark results with all 3, it is clear that these are memories aimed at 3 different market segments. While all three meet our requirement of costing less than $200 for a Gigabyte, the PC3200 Premier is the more traditional Value RAM that will work on almost any motherboard. The second OCZ memory, PC3200 Gold, will appeal to the enthusiast - particularly those enthusiasts who foam at the mouth over OCZ VX at 3.6V.
Specifications
OCZ PC3200 Gold is the only memory in the Value RAM roundup to be rated at 2-2-2-5 timings.| OCZ PC3200 Gold (DDR400) Memory Specifications | |

| Rated Timings | 2-2-2-5 at DDR400 |
| SPD (Auto) Timings | 2-3-2-5 |
| Rated Voltage | 2.6V |
The SPD is set for "auto" timings to 2-3-2-5. To achieve full 2-2-2 timings, you need to adjust memory timings in BIOS. This is the first opportunity that we have had to test BH5 with high memory voltages. The DFI nForce4 SLI has adjustments to 4.0V in BIOS, so we were able to see for ourselves if the BH5 legends were really true.
Test Results
3.4V is hardly the kind of voltages available on most motherboards - particularly those boards that might use Value RAM. To get this kind of voltage, you need a production DFI nForce4 board - Ultra at about $133 or SLI for $184 to $215. You can also achieve these voltages on many motherboards with an OCZ DDR Booster at about $40. What you can do with voltage and BH5, however, is amazing.| OCZ PC3200 Gold (DDR400) - 2 x 512Mb Double-Bank | |||||||

The original BH5 was great up to about DDR450 at decent timings. Above that, it quickly gave out of range - or at least we thought it did in those days. It appears that BH5 with voltage allows 2-2-2 timings to be maintained to levels over DDR500. Frankly, for most users searching for Value RAM, this OCZ PC3200 Gold should be considered as very good and useful to about DDR450 to DDR460, at voltages of 2.9V and lower with very good 2-2-2 to 2.5-3-2 timings. Mad overclockers can consider this an incredible bargain. Feed this value BH5 the voltage and it will deliver at 2-2-2 timings. If you have one of the DFI nForce4 boards, this is one of the memories that can show off what high memory voltage can do.
We have found Aida benchmarks to be very useful in examining read/write performance and memory latency. Aida 32 is now available as Everest Home Edition, a free download from www.lavalys.com.

Maintaining a constant CPU Speed of 2.4GHz and constant memory timings of 2-2-2, we measured the impact of increasing the Memory Speed from 200 to 240, a 20% increase. Both Memory Read and Memory Write performance increased by about 15%, while Latency improved by a similar 14%. This translated into improvement in game FPS from 4% to 5% at a constant CPU speed.

when did value ram cost $200 for a gig...dvinnen - Monday, April 11, 2005 - link
Anyone else finding these Value VX moduals? The link above timeings are 3-4-4-8, not 2.5-3-3-7.JarredWalton - Monday, April 11, 2005 - link
Please remember that it is rarely feasible for reviewers/sites to go out and buy all the hardware for a roundup. Wes submitted requests to several manufacturers, and this is what *they* felt like sending for testing. Of particular note is the comments from Corsair - they are not alone in rotating chip types on their value RAM. Maybe that is why several companies (i.e. Mushkin) didn't simply send their cheapest RAM.Looking around at various resellers and the pricing Engine, there are quite a few other RAM manufacturers/models out there worth considering. Corsair, Crucial, PDP, PQI, G.Skill, and several others have some really good RAM at $150 or less. You can even find PC4000 rated RAM for around $160 now.
Trust me, it's not practical to try to do a roundup of ALL value RAM. There are just so many models out there, all with different performance characteristics. If you don't want to overclock (at all), most of the $90 to $120 RAM will work well.
We should also have a "Your Mileage May Vary" clause in the article, as what Wes achieved is by no means a scientific sampling of each product. That would require at least 10 samples of each, and when you take the amount of time required to test OC'ing on *one* DIMM setup, it would take months to complete a scientific sampling of RAM.

quite right tony, was well done and hope to see further editions of the article. paying less and getting more is always good :)bigtoe36 - Monday, April 11, 2005 - link
Typos's..."seem" is seen, "we" is were...se we all make mistakes.bigtoe36 - Monday, April 11, 2005 - link
VX runs well with 2-3-2 timings with lower voltage. I have seem 233fsb 2-3-2 at 2.8V or so which is a little faster than 2.5-3-3 at the same fsb ;-).Regarding the modules that we not tested, you have to remember there are hundreds of different types of ram, not all can be reviewed in one go, I suspect this review alone took quite some time to complete as the AT LABs are a real busy place...i know Wesley is VERY busy not only reviewing but also pushing manufacturers to get boards overclocking better and pushing the enthusiast movent forward.
If only you guys had any idea of what Wes has done for the enthusiast over the past 2 years, i do and please take it from me the boards you are seeing at the moment are the fruits of that work.
Well done Wesley, nice review as always, even with the odd typo in amoungst the 8K words you wrote ;-)

Well, anyway, what about the decent Mushkin CAS 2.5 for $84? It seems like a much better deal than the one they tested.http://www.newegg.com/app/ViewProductDesc.asp?desc...

wouldve like to have seen mushkin blue line and twinmos tmii400, both are supposed to be good comptetitors to the Value VX/BH from OCZ.Cygni - Monday, April 11, 2005 - link
They reviewed Value ram from the MAJOR mfts, they didnt review no name or OEM pieces, just brand name retail stuff.bobsmith1492 - Monday, April 11, 2005 - link
Who picked these.... :(What about the V-data 3200 CAS 2.5 ram for $70/gig at Newegg or the Mushkin CAS 2.5 for ~80? The ones in the review seem more expensive for slower ratings than most of the stuff at Newegg.
That said, the $115 VX value sounds pretty sweet.
