Great deal for those of us still using socket 939. I picked mine up this afternoon at my local Fry's -- it runs great OC'd to 440MHz @ 2-3-2-6 timings. Best of all, for the first time I can run 1T command rate! Previously I had 2-512Mb sticks and 2-256Mb sticks of Corsair ValueRAM running in DC mode for a total of 1.5Gb RAM. I could not boot or load windows at anything better than 2.5-3-3-7 and 2T. So this is a nice little boost for my system.

Now I'm eyeing the AMD Athlon 64 X2 3800+ (for socket 939) @ Newegg for $115 ... hmm.

Bottom line, 1T is faster. Basically we're talking about memory latency and speed.

Timings are not that big a deal with AMD64's, but it's nice to have ocable ram especially at a good price.

1T vs. 2T command rate is pretty significant -- highly significant in terms of synthetic benchmarks, debatably significant in terms of real-world performance. The same goes for other RAM timing values. None of which is important to the non-enthusiast. But these forums tend to be populated by enthusiasts.

I got in on this about 2 weeks ago, definitely good RAM. I thought DDR prices would go down more but they never have, so I just got these.

Thanks OP, I saw this a couple days ago and resisted. Your post broke me down.

actually 1t command rate yields significant performance, especially AMD64.

I average about 200-point gain on 3dmark06 using 1T cas 2 versus 2T cas 2.5.

Take it for what its worth.....there's a difference nonetheless.

good deal ...i just spent nearly $100 for 1GB Kingston HyperX DDR PC3500 at the 'Egg
[2.5-3-3-6 although it will run at faster timings]

tighter "timings" are for performance ;)

i probably *didn't need* PC3500 over this quality PC3200 :p
--this RAM's actual timings are 3-3-3-8 at 2.6V but it is tested to run lower

oh well, 1.5GB RAM will have to *do* till my next DDR2/3/4 upgrade

good deal!

How about the performance difference in single core AMD64 processors in a single channel memory configuration vs dual channel? Mine is set up in a single channel configuration right now. I have never seen any benchmarks for this, every test seems to use dual channel with no regard to single channel.

Someone at diy-street (formerly dfi-street) said this memory didn't o/c well in DFI's NF4 boards. Anyone have experience with this. I have an Ultra-D, but I haven't tried overclocking yet.

Check out this whitepaper (PDF) that discusses the difference between single-channel and dual-channel memory. It's a little bit dated (2003) but I think the data is still relevant. It discusses both theoretical peak bandwidth differences and real-world benchmark differences. In both cases, the advantage of dual-channel is pretty significant.

Example: Peak Bandwidth @ DDR400 (PC3200)
Single-Channel -- 3.2GB/s
Dual-Channel -- 6.4 GB/s

No, which I why I don't buy stuff from there. :( They need to get with the times.

The theory of improved performance is big however it does not translate into real world performance all the time. Back when dual channel was the new technology in town, there were many benchmark tests on the then current platforms. What was determined that it was benificial on the P4 however the gains on the Athlon XP were almost non existent. I have not seen a review on how much the true performance gains are on the Athlon 64 single core however as I said, my setup is currently running single channel and I would love to see what kinds of gains I can achieve with dual channel.

Like others have said, dual channel makes a significant difference and is how iDDR should be ran imo.

Performance ram does not make a big difference in performance for a64 rigs. It helps in stable/flexible ocing, but mhz > timings. Anyone who tells you different is a nub. There was a thread in the ocing forum where tons of different ram were tested and in most games the difference between expensive (at the time) DDR/lower timings and cheaper ram like Corsair Value Select was under 5% at the same clocks. Since expensive DDR was 2 - 3 times more than VS, it was recommended that you grab cheap (but stable) DDR and use the saved money toward a better graphics card.

Now if you can get better ram for around the same amount as VS, then get the better stuff, but it won't give you noticeably more performance in gaming.

I'll try to find the thread with all the benchmarks later. It was done back when AMD64 was the best proc and everyone was ocing them. Now in A64's twilight, I don't think much could have changed.

DFI mobo were/are picky with ram & power supplies. May be the last DFI I buy.

Can't find article but I remember doesn't make a big difference in frames/second in gaming but does show in sisoft sandra benchmarks.

Again, not real world but only for those people who care about synthetic benchmark numbers.

from what is on Fry's website it seems that the 2-3-2-6 is for a slightly higher voltage as listed under their detailed description. New Egg's website only states in specs a running voltage of 2.6 which is supposed to support only 3-3-3-8

from outpost:
Detailed Description [return to top]

* Power supply : Vdd: 2.6V + or - 0.2V, Vddq: 2.6V + or - 0.2V
* Double-data-rate architecture; two data transfers per clock cycle
* Bidirectional data strobe(DQS)
* Differential clock inputs(CK and CK)
* DLL aligns DQ and DQS transition with CK transition
* Programmable Read latency 2 (clock)
* Programmable Burst length (2, 4, 8)
* Programmable Burst type (sequential & interleave)
* Timing Reference: 3-3-3-8 at +2.6V / 2-3-2-6 at +2.65V
* Edge aligned data output, center aligned data input
* Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)
* Serial presence detect with EEPROM
* High Performance Heat Spreader
* PCB : Height 1.250" (34.75mm), double sided component

I'm hoping this is the case so I can play games like stalker and and FEAR without using 500 meg of virtial memory!!
