Here is a link:
A-Data PC-4000
This is absolutely a great memory
but i couldn't find this memory selling in US

Link Fixed

Can't wait for more DDR500 chips from Hynix or Winbond.

 

[Soulkeeper]

yeah something that has better latencies would be nice
that junk is kinda weak if you ask me

it seems everytime they increase the clock frequency of memory these day they compensate by lowering the latencies

maybe it really is time for ddr2

Agree. I'm totally unimpressed with the current crop of "DDR500" ram out there with the pathetic 3-4-4-8 timings and the high price tags.

Its no faster than DDR400 with tight timings. It just costs more.

Hmm, is Hynix memory highly overclockable? Are they better than Micron/Crucial? Since it seems like I haven't seen anyone else mentioned Hynix yet the memory I'm using came from my friends Dell Dimension XPS are 4 sticks of Hynix PC3200 DDR400 512MB 3-3-3 sticks as well as the P4C-3.2Ghz. I got things up to 232FSB at 3-3-3-8-8.

These A-Data can do up to 281mhz at 3,4,4,8 setting while others like OCZ or Corsair would probably do 270

but these are prolly considerably cheaper

cheaper doesn't really matter
what matter is how the performance is

price is always a big deciding factor for me. btw, both XMS pc3700 and pc4000 is rated at 3-4-4-8

edit: by cheaper i meant costing less. i think you took it as being of cheap quality

3-4-4-8 is not what I would call good performance.

niether do i but you are getting the same timings as XMS at (prolly) a cheaper price

GeiL is offering the "best performing" pc4000 @ 2.5-4-4-7

 

[lookouthere]

but A-Data can offer you 3 4 4 8 at 281 while you don't others could do it or not......

You guys can see some 4x 256MB ADATA PC4000 results I posted here

These are the exact same ADATA sticks in the OCAU review, as 8 of the 12 sticks in the OCAU review are mine which Chainbolt bought on my behalf

I should be able to compare these against

On the OCAU, they said using Abit IC-7 wouldn't go over 260
only the Asus boards can do over 280. that is why you are getting a poor results

yeah that's why i got myself an Epox 4PCA3+ with max 3.3v vdimm options

having a higher volt on ram does not neccessary will increase your ram speed

it may or may not.

anyway, any idea where/when we could buy this stuff?

actually it does in most cases ADATA PC4000 @ 3.1v manages 292mhz 1:1 from posts at xtremesystems forum and Japanese memory ranking table site which caused the whole tidal wave of interest in ADATA PC4000 has the top 3 ranking memory as ADATA PC4000 with 300 - 314+ mhz 1:1 with 3.4-3.6v vdimm

so that means ADATA PC4000 is very overclockable

You're totally wrong. Running 275mhz fsb, 1:1 with 3,4,4,8 timings will perform a LOT better than running 275mhz fsb 5:4 memory ration on 2,3,3,6 (im being realistic it's very hard to find memory that will run DDR 450 @ 2,2,2,6)

And you tested this and have benches to back that up right? 275 @ 5:4 = DDR440. There is memory available that will run 440 @ good timings. I dont where to find a bench with those exact numbers, but here is a review comparing PC3700 and PC3500 memory. The PC3700 was slower due to the slow timings.

Here is a post from ABXzone of someone "upgrading" to PC3700 that lost performance also due to the slow timings.

Upgraded to XMS3700 but lower 3DMARK03 score!?

By using 3DMark03 to judge what is my maximum FSB/memory/video setting for my P4 2.8c cpu on my Asus P4C800, I obtained the following results:

1) no name PC3200 (1G); FSB=235; 5:4 ratio; 2-3-3-6 SPD; result = 4375, CPU=730

2) Corsair XMS3700 (1G); FSB=235; 1:1 ratio; 3-4-4-8 SPD; result = 4316, CPU=759

3) Corsair XMS3700 (1G); FSB=250: 1:1 ratio; 3-4-4-8 SPD; result = 4328, CPU=810

Another memory article You will have to translate

Couple of points that are key:

1) Synthetic mem benches (SiSoft Aida) DO NOT represent real world perform. I dont know why people waste so much effort on them.

The Tweakern -, we put our experiences to tunern and Uebertaktern likewise again to the heart: Outstanding scaling synthetic of memory bench mark á la SiSoft Sandra, AIDA32 or similar applications do not reflect results apportionable on practice again!

2) Async with fast timings ~= to 1:1 with slow timings
2b The high DDR speed high latency memory is not all it is cracked up to be unless all you care about is SiSioft and Aida benches.

It showed up also here that synchronously (FSB/Speicher) a system with relaxed latencies, operated with 250 MHz, could not even compile 1 % advance in performance to an asynchronously operated (250 MHz FSB/200 MHz RAM) system with shorter latencies. Thus so-called DDR466 or DDR500 memory does not make necessarily sense, in particular if one considers the higher initial costs.

Those sticks are rated to run at those vdimm settings?!?! :Q

I can understand wanting tighter memory timings, but electrocuting ram sticks to achieve that doesn't seem like something that can be done for "long-term" use.
