Value RAM Roundup: Computing On a Budget

Mushkin EM Series PC3200
Mushkin is admired by many computer enthusiasts for the quality of their products and the customer service that they provide. In the past, the only way to buy Mushkin memory was direct at www.mushkin.com. Recently, however, Mushkin has also been available through web retailers like Monarch, NewEgg, TigerDirect, and AxionTech. In Canada, Mushkin is available through NCIX.If you do order direct from Mushkin, you will get their famous "pillow pack" that cradles their memory in an air bubble. The point is that Mushkin makes solid products, stands behind their products, and treats customers well.
Mushkin EM is their Value line product, and like other Mushkin memory, it comes in a sealed anti-static bag instead of the fancier packaging that many others use. All Mushkin memory, even this Value product, comes with heatspreaders.
Specifications
The Mushkin EM is specified at the unimpressive specs of 3-3-3-8, but keep in mind that Value RAM is normally about price and not performance.| Mushkin EM Series PC3200 (DDR400) Memory Specifications | |
| Number of DIMMs & Banks | 2 DS |
| DIMM Size Total Memory |
512 MB 1GB |
| Rated Timings | 3-3-3-8 at DDR400 |
| SPD (Auto) Timings | 3-3-3-8 |
| Rated Voltage | 2.6V |
The EM memory performed fine at stock DDR400, but it is another Value RAM with no overhead.

All the memory manufacturers generally have access to the same memory chips, and we can only surmise that Mushkin chose the chips in our EM sample for price. The manufacturer chose which Value RAM to send us for testing, and we can only wonder why Mushkin chose to send us EM for this roundup. We have tested other Mushkin Value RAM over the years, and we have generally been pleased with the performance and head room of Mushkin value products. Our advice would be to choose this Mushkin EM if you will only run at stock speeds. It could be that the memory is just a bad match to the AMD memory controller or the DFI, but further testing would be required to see if the EM performs better on other platforms.
Aida 32 is now available as Everest Home Edition, a free download from www.lavalys.com. We have found this benchmark to be very useful in examining read/write performance and memory latency.

There's little to analyze with such a small performance range. We would suggest that you choose another Mushkin value RAM if you want to shop for a Mushkin product at low cost. The Mushkin website shows a 1GB CL2 DDR400 kit at $155 compared to $147 for the EM.

#39,"2) RAM multipliers are usually limited. If you have a standard set of 400, 320, and 266 speeds, you could only achieve DDR400 speed at a CPU frequency of 250. Anything lower than that would be running the RAM at less than 400. Most A64 CPUs can't do 250 on air at stock multipliers (the low end ones can) so they will be running less than optimum ram speed. That's where you could lower CPU multipliers or use a board like the DFI with lots of intermediate RAM ratios. "
I'm not sure I'm following.
With a 9x CPU multiplier, DDR266 memory divider and 312MHz reference clock the memory would be running at DDR400.
With a DDR200 option you could go up to 400MHz on the reference clock. That means that no DDR400 memory will limit the overclock of a CPU with a 9x multiplier.
"1) There is an Asynchronous Latency penalty, which can be tweaked somewhat on boards with better BIOS options like the DFI. It is not, hoever, the kind of asynchronous penalty you see on a FSB board like Intel. "
In my own tests there's no real-world penalty at all. I compared an Athlon 64 running at:
REFCLOCK: 200MHz
Memory Divider: DDR400
CPU multiplier: 9x
LDT: 5x
with:
REFCLOCK: 300MHz
Memory Divider: DDR266 (DDR400 effective)
CPU multiplier: 6x
LDT: 3x
The results where near identical.
"In other words, the easiest way to consistently improve memory performance is 1:1 memory speed."
There's no memory fast enough to run at 1:1 with an Athlon 64. ;)
An Athlon 64 at 9*200 is on a 1800/9 ratio with DDR400 memory.
I'm sorry but I stand by what I said before, there's no reason to invest in memory if you want to overclock your Athlon 64, only if you want to overclock the memory as well.
Kind of on the subject, I hope the round up of AMD PCI-E boards (there is one coming right?) tests the best reference clock the motherboards can achieve without memory as a limiting factor, unlike the reviews before.

Excellent review, both for the modules it covered and what it didn't.One small point- there is no such thing as 1:1 memory timings with A64 processors. The reduced latency and higher performance that a 1:1 ration gave when the processor to chipset FSB was running synchronously with the chipset memory-controller, is irrelevant with the Athlon 64 as there is no intermediate bus operating at a differnt speed to the memory controller to cause overheads. Selecting a lower memory speed just changes the CPU:Memory ratio in the processor.
The memory on an Athlon 64 system works just as efficiently (though ay a lower bandwidth of course) if set to DDR333 as it does at DDR400, which means there is no real penalty when overclocking in choosing a lower memory speed to compensate for the increasing bus speed.

http://anandtech.com/memory/showdoc.aspx?i=2392&am...> Transcend is another memory that costs just $100 for a Gigabyte and yet manages to nearly reach DDR550 in overclocking.
550?
The table claims 510 (2 x 223), but 2 x 223 = 446.

Is Lavalys sponsoring this article? Why is that paragraph repeated on every page?JustAnAverageGuy - Tuesday, April 12, 2005 - link
I would have liked to see Mushkin Blue($147 per GB)

and Corsair VS 2.5

I won't whine about the voltage, that's been done before :)

Why isn't the OCZ4001024WV3DC-K on the OCZ site???CobraT1 - Tuesday, April 12, 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
See this link for both.

Hope this clears up the confusion.

Wesley - Fair enough. But when that ATACOM link posted in #44 shows 3-4-4 even on the label in the picture its hard to tell who to believe (and its hard to read the part # on it). If its all the same chip then fine... but why label it differently then? Buyer beware?Maybe I am off base...

I get real tired pushing ferrari's out of my driveway. There isnt any racing alcohol available to me, sometimes I have my neghbor tow me to work in his chevrolet cobalt
