Infineon are producing again so supply should come good for those waiting, we are also checking new IC's all the time so please don't think we are sitting still on this.

Load and timings are the issue with 3D i feel, plus the internal draw particular IC's have. The micron die may have less load than the infineon die so making 3d fail before it did on the micron..hard to say without measuring etc and being honest its not really worth the time playing.

4000EB is rated at ddr500, there is headroom but its not guaranteed.We see a lot of RMA purely due to the modules not overclocking as high as the end user wanted...this is fraud and we may have to tighten RMA due to this abuse. I used to buy twinmos BH5 many moons ago and speed bin it my self, sell of the poor clocking modules and keep the rest, i NEVER RMA'd because they did not overclock like I wanted, i just sold them and moved on...
RMA abuse is wrong, take note of my words here, the support we offer you guys depends on how you conduct yourself with your ram purchases.We support the enthusiast as long as they support us and are fair with us.

One of the reasons why online retailers like newegg are starting to charge more for their products.

no kidding, sell your crap off guys, I bought 3 gigs of redline to play with, I didn't RMA the other sets I didn't like :P I sold'em off on the forums and locally. Don't be lame. A defective product is one thing, rma'ing because you don't like somthing that works is another.

i didnt ask for an RMA when mine wouldnt go past 251. I just posted up my results and said i was disappointed and would probably sell the EB's. One of the local OCZ reps told me to PM him and he'd get me fixed up. I ended up RMAing the kit, but i never asked for an RMA, i merely said i was disappointed and not very happy with them. I do not advocate calling up OCZ and telling them you are not happy with your OC and want an RMA at all. But i was extremely blown away at the service i did recieve. I dont expect that from any manufacturer, but they went above and beyond to make a customer happy and i applaud them.

Ok Guys im testing now, just got my water cooling system on here and will let you know how it go's i upped the volts too 1.53 on CPU Load 39c I test for only 1 hour on prime but it was stable again @ 273 3-3-2-5 :D Im going to test it more and see how high i can get these babies, im over 3003 MHz as we speak this Opty loves the water so far.

Any updates on this? Has anyone spotted the new batch anywhere...?

-Thanks

The newest PC4000 EB batch from OCZ is CE-6

Yes, they have a problem with 3D over ~260MHz. But if you stay under this speed, they really gives fast timings :toast:

I can run my 2GB set up to:
CAS 2 3 2 7 @ 230MHz
CAS 2,5 3 2 7 @ 255MHz

All test was run with 2,7Volt on the memory and at 1T with Ultra-D + opty165

I`m not easy going on stresstesting before I call something stable :nono: And please.. DO NOT REMOVE THE HEATSPREADERS LIKE I DID (It`s extremely dangerous and you will void your warranty)

That will do - if only I could get some :(

People who abuse RMA should be beaten like this: :slapass: but not screw other honest users who really need to RMA.

ArcticOC,

Did you just pick that up? If so... where?! :D

Got them from OCZ HQ themself one week ago, so it`s fresh stuff. The IC`s was produced 6weeks ago if you study the picture. Don`t know any retailers that got them stock here in Norway where I live.

They can run cas 3 3 2 8 @ 280MHz SuperPI 32M stable, but anything over 260 gives problems with 3D :(

Since I live so close to the Northpole, "Santa" drops by every now and then with some candy ;) No, the stick comes from a RMA I had going on.. Initially got some PC4000 EB PE that turned out to be fakes, they had samsung UCCC chips on them and no BP808!

EDIT: It should be 280MHz, damn was i drunk last night, thats a major typo :p:

That would be nice :D

380mhz woah :D

I wonder if mine are different then yours, I got mine from the very first batch that came out. I can play COD2 @ 273 1:1 but BF2 I lowered it as it seems too eat much more ram too 267 1:1 and its stable as a rock here, so i was wondering if they mite have changed something on them ?

They are defenatly not the same stuff that was deliverd some months ago, but I like the new ones too, they run really well with low timings :)

I cant uderstand why they dont like 3D at high speed?! They can run prime, superPI and memtest86 all day long at +270MHz, but 3D is a no go :( Are there some complcations regarding my dualcore opteron mem-controller? anyone?!

That 380MHz was a typo, major typo.. it`s 280MHz that was correct:toast: hmm.. was I really that drunk last night?! ;)

I just got the PC4000 EL 2x1GB pack and get about 290Mhz if I keep them cool with a window AC. They run just fine under any other circumstance at at least 285Mhz. Timings are not that bad either 3-4-3-8-1T still.

same here
i was able to bench 3dmark 2k1 at 266x10.....but when i throw a divider....aaargh
my rig is quite nice with this 2 g kit....its just to bad they dont clock higher
once more a big thank you to ocz and specially to ryderocz and jimmi houn
ocz tech support is really the best i have ever seen :fact:

Just got the memory 3D stable @+270MHz

I upped the chipsetvoltage from 1,5 to 1,6V and the LTD-bus from 1,2 -> 1,3Volt

Does this mean this memory is very hard on the chipset and the LTD bus?

I belive it only relates to the LTD-bus, as the problems only appers in 3D benchmarks. Upping the voltage solved the problem for me :) The LTD-bus is one of the parts that link the memory -> CPU -> chipset -> PCIe (videocard). I belive 2GB stress the bus more than my previous 1GB UTT/BH-5 kit

I love this memory more and more

I will come back with screenies form the final results, I always stresstest for several days before certifying the speed as stable.

if it's the chipset/bus then how does that explain why some modules did better from first batch unless the difference is also due to not all motherboards being the same ? anyone try the ram in more than one of the same motherboards ? i.e. 2 or 3 DFI NF4 ULtra-Ds ?

Yes, I see your logic.

Anyway, 3Dmark was running for 8H straight now. It would crash instanly before I upped the voltage. I dont have any other board to try the mem on right now

Its probably exactly like Tony said, some chips suck up more juice than others (or require), and that is taken away from the CPU/Mem controller once you overclock beyond 260MHz, giving more voltage makes sense (LDT bus voltage goes straight into the ondie mem controller).

Also, it probably varies from one Ultra-D/SLI-DR to another (old layout vs new layout). New layout has more stable voltage lines (cleaner).

Just got my EBs in to replace my dead (again) Ballistix.

We'll see how it goes.

Be back later tonight with screenies and max 3D OC.

I've heard from DFI that the different revisions in the boards only signify what BIOS it is shipped with

They do. Thats why I was referring directly to different layouts. It has been proven that there is an earlier and later layout (the later being the better). Its easy to check, and maybe we should ask people to identify their layout if they post OC results.

EDIT: Maybe we should a database going here, or maybe anyone with both layouts could test 2x1GB EB kits and see how performance varies from one to the other.
