Looking at the performance of the Corsair Vengeance 4x4GB kit, we found out that not all RAM solutions are made equal.

This is a pretty interesting result! I'd be very curious to see what speed/timings do to the results. i.e. does 1833 RAM give a significant advantage?

Thanks,
Chris

We're not doing any overclocking for these reviews so they're standardized and have stable results. I would expect a moderate bump in performance when OCd.

It looks like the data may be withing the margin of arror for the benchmarks? No one is going to see a 2-3% diff. in speed however.

Some were close, others like that webserver trace had massive differences.

It would be nice to know if it makes any real world diff however. Never under estimate a hardware vendor's ability to figure out a means to inflate benchmarks... ;)

Well in the scope of this review, we weren't looking at the performance of the system per the RAM speeds, but the speed of the RAM Disk itself. Kind of like comparing one SSD versus another.

Understood. My point is typically a few percent change in RAM/CPU/HD/GPU performance is not even detectable is system use.

Even do interesting results, i was missing a lot of data/test i was bin interested in.

Mainly a comparison to a SSD.
And if possible more memory 32GB or 64GB.

Good review.

I am using Qsoft's RAMdisk Enterprise and I am very happy with the results. I use 8GB of my 4x4GB (G.Skill Ripjaw DDR3 PC3 12800)setup.

Here is a comparison of various software RAM disks:

Next up is a larger set of Corsair Vengeance RAM, 8 x 8GB if I recall. On the SSD testing, it's not even close, especially for tiny SSDs, so it's kind of pointless to compare.

Great, cant wait to see the test ^_^

On the SSD testing, it's not even close,

I know, i use a 58GB ramdrive my self. ;)

But how will people understand how fast a RAMdrive is without comparison.


especially for tiny SSDs, so it's kind of pointless to compare.

That not really the point, i think.

Your not comparing size to size.
But speed against speed.
And if you compare, price versus price, a set of 8x 8GB is more in the price range of a 240GB OCZ RevoDrive 3 X2

http://www.storagere...w_firmware_0009 And the raid set review.

You tested those all ready, would be nice to have the test data of those as a comparison.

On the upcoming 64GB review I'll try to work in some relevant numbers for comparison.

*cough* And how about testing different RAM Disk software/drivers? I see substantial speed differences using previously DataRAM vs. now RAMdisk Enterprise *cough*

We are working on doing a side by side piece adding in other software into the mix ;)

I am looking forward to that. B)

Its gone be a hell of a labor intensive review then.
But properly really worth it :)

This is pretty much the philosophy behind each of our reviews. We put a ton of pride into the way we handle reviewing products and readers and manufacturers love it. We actually had 2 weeks of testing in on that Intel SSD 520 review. Many overnight per configuration benchmarks but it added up into review that was worth it :)

Hi Kevin:

You probably don't have the setup, but I'd be quite curious to see what the performance delta is between this and say a 2600k. I'd imagine it's about twice the speed (quad vs. dual) but it seems that the 7GB/sec is pretty far away from the max memory throughput of 37GB (21GB for the 2600k).

Thanks,
Chris

You forgetting one important detail, the RAMdisk is part of your main memory, but its not part of your work memory.

So if you read out of memory you have some steps before you can actually use the data.

Very simplistic.

1 read data from RAMdisk
2 copy temporary the data to L3 of the CPU.
3 Write from L3 to work memory space.
4 Repeat step 1 to 3 if needed.
5 Data ready for use


And with ever read and write step you have latency, in theory you should get about half the memory bandwidth, in practice there is a bit of a overhead.

Still, its still a lot quicker then what any SSD can do when it come to bandwidth.

ps. Kevin is there a ETA for the review, just wondering when it will be up.

Kevin/Brian, is there a ETA for the 64GB review, or did i somehow missed it.

We've just been buried with other gear, we still plan to do this review though. It's on the marker board at least, so that means we know we need to do it ;)

Still have not dig your self out of that mountain of other gear, to do a test?
