Value RAM Roundup: Computing On a Budget

OCZ PC3200 Value Series: "Value VX"
OCZ VX emerged as our memory performance leader in our recent memory review, OCZ VX Revisited: DDR Updates on DFI nForce4. Rated at DDR500 speed at 2-2-2 timings, we quickly learned that you needed a lot of memory voltage to get the most from this memory. In fact, VX really requires 3.5V to 3.6V for best performance. This requires one of the new DFI nForce4 motherboards, an add-on OCZ DDR Booster, or a motherboard memory voltage mod to provide the voltages VX demands.The other part of the VX equation was cost. OCZ bins VX and tests at DDR500 2-2-2 speed, and the cost of that selectivity and guaranteed performance is about $270 for a Gigabyte of RAM. As performance RAM goes, this is a bargain price, but we never considered VX a Value RAM until OCZ dropped a surprise on our doorstep.
With the introduction of DDR500 VX, OCZ announced that they would be also producing a "Value VX" rated at DDR400 and lower voltage. Basically, this Value VX would be an unbinned part not tested for high voltages and high overclocks. That "Value VX" is now on the market as OCZ PC3200 Value Series and selling for about $115 for a pair of 512MB DIMMs!
Specifications
OCZ rates Value VX at the very conservative 2.5-3-3-7 at DDR400 at default voltage. The memory does meet these specs, but when you crank up the voltage, these "Value VX" DIMMs turn into a different animal.| OCZ PC3200 Value (DDR400) Memory Specifications | |

The binned and tested OCZ PC4000 VX reaches a higher speed of DDR530 at 2-2-2. That just proves the value of binning and testing for performance. But how can we complain about a memory that costs 57% less than 4000 VX and still performs with complete stability at DDR490 at 2-2-2 timings? Frankly, we can't.
You bargain hunters who want to play with VX, 2-2-2 timings, and high memory voltage will want to grab a pair of Value VX. They aren't binned, but we suspect that most will reach DDR480 to DDR500 if you supply the voltage - and some may do even better. That translates into a Clock frequency of 240 to 250, which should be more than enough to supply 1:1 2-2-2 to any AMD A64 at stock multiplier. A 2.4GHz 4000+ would be 2.88 to 3.0GHz at 240 to 250, for example - probably more than what the CPU can do with air cooling. At $115, for a Gigabyte of Value VX, there is now no price barrier to providing 2-2-2 1:1 memory for any AMD CPU - provided you can supply the voltage.

Performance patterns are exactly the same as seen in our recent reviews of VX memory. The unbinned $115 DDR400 memory reached DDR490, while the binned $270 DDR500 version reached DDR530 - with 2-2-2 timings all around. If you want assured performance, go for the DDR500 tested part. If you want low price and lots of potential, OCZ PC3200 Value Series has your name on it.

I have to agree that a value ram analysis would be more useful if it checked stability of less well known brands, such as memory pro. Also it would be useful to review sodimm ram 512MB modules, as many budget laptops come with scanty ram and it is usually cheaper to add it aftermarket than buy more from the manufacturer.Pjotr - Wednesday, May 4, 2005 - link
Oh, I forgot, the package does say it has EVP!Pjotr - Wednesday, May 4, 2005 - link
"If you are interested in the OCZ Value VX, note the differences in the two part numbers, one with a "W" and one without.Value VX = OCZ4001024WV3DC-K
2.5-3-3-7 (picture) Supports EVP (Extended Voltage Protection)
Value = OCZ4001024V3DC-K
3-4-4-8 Does not Support EVP"
I bought the OCZ Value 2x512 RAM with 3-4-4-8 timings for $115 at Fry's, so basically I got fooled at that price?
I have this setup: DFI nF4 SLI-D, X800XL, Winchester 3000+.
I've tried this RAM and it won't run at CAS2 at all, I think, I need to do some more work. I've tried 3.0 to 3.2 V in general. I do get it to run 2.5-3-3-8 up to about 240 MHz, from there I need to relax to 2.5-4-3-8 and I then hit 250 quite stable, 255 SuperPI stable but not 3DMark stable.
I'm a bit disappointed now... any hints? Shouldn't I be able to get better timings at 240-250 MHz too? The memory chips are marked OCZ, not blank. Don't know exact markings right now.

Edit I am an idiot and don't know how to read page 2. Thanks for a good article. Do compliments from idiots count ? As far as the voltages go I was happy to see what it "could" handle if this is not anything that I would ever do in my motherboard, the curiousity inside me found this interesting. I thank you for pushing the ram to the limit because in the long run I think the ram that tolerates that type of voltage would have an advantage in OC'ing. I was very curious about the posts earlier saying that you can keep your Ram at ddr400 (effective) and increase your FSB and have no asynchronous lag. This probably isn't the place for that discussion but I nonetheless was very interested in this information. Maybe a review of that is in order for the next Ram test if you have the time ?Baldeagle76 - Friday, April 29, 2005 - link
I have a question. After reading this article I went to NEW EGG to look up the current prices of RAM. Specifically I was looking for the prices on the Value VX ram. Sadly, I did not find anything that fit this description. I don't know if it because I don't know what I am looking for. In None of the titles of the RAM did they mention Value VX. Value was mentioned but how do I know if it is the VX or not? Also looked for the OCZ value BH5 and again I am not sure if I don't know what to look for or if they are out of stock because I didn't see any. It might be helpful for consumers making purchases based off of the articles on Anandtech to include the manufacturer part number so we know whether or not we are getting the same thing reviewed or not. Maybe you could help me out with this because I was looking at getting some of this 512x2 for a second machine i am building but would definetly want the stuff reviewed and not stuff I don't know how good it is. Just including the manufacturer part number would be very helpful in this regard, especially for ram.Baldeagle76 - Friday, April 29, 2005 - link

wow, honestly now. For a reputable website, why is it that the level of english used in this article could be bested by a 4th grader.YOU CANNOT pluralize 'memory' If you want to refer to more than one you use 'pieces of memory' or 'memory sticks'. Also when you say 'the memories' you can bloody just say 'the memory'. It is not a hard concept. Would you see this in a newspaper? NO. Same should go for online articles.

I just got some of this ram, 2 gigs after reading the review "0CZ4001024WV3DC-K" And all I can say is WOW!!!!! 2-2-2-11 @2.9 220 X 11 on my 2500m/ABITAnd for $115 a gig. Runs better then my old bh-5

#93 As Wesley said in the opening paragraph, the PURPOSE of this RAM review is to help the reader find the combination of components yielding the best overall "system performance" for the money.That's the Big Picture that you need to keep in mind.
In that context, the combination of Crucial Ballistix RAM, a DFI nF4 mobo, and a Venice 3200+ CPU at 10 x 280 MHz is a very attractive one, in terms of system speed versus cost.
Of course, "system performance" can include other things than just speed, such as fault tolerance, noise, heat, portability, availability, etc.
I happen to value low noise as well as high speed, which is why I suggested the other components, too. I simply hope that my comments give other readers a few ideas of their own.
And that's the point of these forums, isn't it?

#92 this is a ram review.wesley: it's interesting to see that the new BH-5, tccd, Micron rev.g, and UTT chip, at 2-2-2-5 timing ddr400, they never reached over 3k on sandra unbuffered test. However, going back to the old P4 2.4C test bed, Mushkin and OCZ 3500 BH-5 running at ddr400 2-2-2-5 had over 3.1k each.
Guess the old BH-5 is still faster than the new one.
