Anybody???:confused:

Buy em and find out :) Its new line with the DHX... though Im pretty sure they arent Micron based.

[screwtech02]

Yeah... I bought some of the OCZ "ATI Cert" memory, and that didnt go so well... :rolleyes: So, i will wait till somebody spills the beans about these....

[Yellowbeard]

I've got a pair on the way that I am going to put into my gamer box and "test". In general, the DHX line is a midrange line under the high end Dominator line. So, massive OCing is probably not going to happen but, I'll get back to you with what these will do for me.

Cool man, much appreciated....:cool:

I just wanted to add a couple of results I had gotten with an average kits, as part of my testing in the lab, a while ago:

2 x 2048MB (4GB) on Asus Striker Extreme @ DDR2-896 5-4-4-12, 2.10v --> 2hrs ORTHOS LargeFFT (http://www.clockmehigh.com/TestingAtCorsair/TWIN2X4096/375x9_DDR2-896_5-4-4-12_6400C5_4GB_ORTHOS_2hrs.gif)
Latencies 5-4-4-15 also possible, with only few Mhz of OC lost. Above OC also stable at 1.90v.

4 x 2048MB (8GB) on eVGA 680i @ DDR2-880 5-5-5-15, 1.90v --> 24hrs ORTHOS Blend (http://www.clockmehigh.com/TestingAtCorsair/TWIN2X4096/366x9_DDR2-880_5-5-5-15_6400C5_8GB_Vista64bit_ORTHOS_24hrs_1.gif)
4 separate instances of SP2004 in order to allocate MAX possible amount of memory on MS Vista 64-bit

Notes:
- around DDR-960 5-4-4-12 is possible for some benchmarking, but not very stable, though;
- most of the time, 1.90v is all you need, more voltage does not seem to be largely beneficial in terms of full stability, just adds heat;
- chips used: Micron D9HNL, 78nm, 128Mx8
- just as Mike (YellowBeard) mentioned, it's a midrange line, at good price/performance point, with still some headroom for overclocking left to play;
- max results on 965P/975X chipset are somewhat lower;
:toast:

Any chance of seeing what a 975x did??

[Yellowbeard]

I'll see if Bachus can toss a set into a 975x board. I don't have my 4096 kit yet so I still can't test it.

Have you tested these modules on a P5K Deluxe?

[chriskurn]

Does anyone have these in stock? I can't find them anywhere.

As soon as I have a bit more time (kind of busy here in the lab lately), I will give it a try in 975X motherboard... Hey Mike :)

Have you tested these modules on a P5K Deluxe?Yep, here you go:

2 x 2048MB (4GB) on Asus P5K Deluxe @ DDR2-882 5-5-5-15, 1.90v --> 18hrs ORTHOS Blend (http://www.clockmehigh.com/TestingAtCorsair/TWIN2X4096/294x9_DDR2-882_5-5-5-15-2T_6400C5DHX_4GB_ORTHOS_18hrs.gif)
That looks a bit better compared to 965P, last time I run 6400C5DHX on Asus Commando...

I hope that helps you guys :)
:toast:

[Yellowbeard]

Nice voltage, I can't wait to get my set.

[chriskurn]

Ok guys, where are they in stock? :)

[BobHarris]

bachus_anonym, if you loosen the timings, will it be possible to get 950 stable?

[chriskurn]

Is their any benefit to upgrading to these if I am already running 4gb - 2 x (TWIN2X2048-6400C4)

I have a P5K Deluxe. (4-4-4-12 2.1v)

Probably not. Do you intend to OC any?

[chriskurn]

Yes I want OC the ram slightly, but isn't 4-4-4-12 better than 5-5-5-15?

[Yellowbeard]

At the same frequency yes, 4,4,4,12 will give better bandwidth. However, in many cases 5,5,5,15 at 1000 will give slightly more bandwidth than 4,4,4,12 at 800. I have no idea how that P5K will handle it though so, you may need to do some testing of your own.

I would suggest clocking the memory first at 4,4,4,12 and getting your MAX CPU OC at a 1:1 ratio. Then, loosen the timings to 5,5,5,15 and see if you can any faster. Then, you can do the same comparison to see how the system runs dividers if you want. However, with PC6400 RAM you will most likely get your best overall performance at 1:1 maxed out at 5,5,5,15 or with a 4:5 "IF" the RAM will run that fast.

Hmm, good to hear... I just picked this up myself for my P5B Deluxe WiFi AP...

Someone else on Ars Technica topped out at 850mhz, I'm wondering how far my set will go.

[ChaosMinionX]

P5K doesnt like super tight timings, I think its a bug since it was designed around DDR3, and sometimes looser timings results in faster sticks with lower latencies....I run faster 4-4-4-10 than i do 4-4-4-4, latency goes down a ton when tweaking performance level, which unfortunately is not an option in bios :(
