So has anyone actually got their EB to work?

Trust me, anything over 3.0v without sufficient airflow is really pushing it.

Good expample is the lan I am at right now.. ~30c ambient temps. With my side fans off and my ram running 2.9v I cant hold my finger to the bare chips.... let alone the vdimm mosfet :eek:

The extra temps have been wreaking havoc all over since the lan started.. :stick:

While benching my KHX3200 at 2.85v 224mhz they do not get more than just "warm"...and there isn't a fan pointed directly at them. Mind you that is low voltage but that isn't far from your 2.9v.

thanks man i may take you up on that.

LOL


I mean with the crazy voltage and oc people mean to throw at it here. Keep in mind people are wanting to see 500Mhz plus out of 3200/3500



most people in these forums that I know of are trying to get there maximum overclock and even with your kingston a fan might incresase the speed

above 2.9-3.0 volts I would not run any ram
without a nice 80mm sitting on top. personaly that is

The EB RAM does get warm at higher voltages. Always have a fan blowing in modules when running high voltages. A fan will do a good job of keeping them cool. The copper heastspreaders are drawing the heat off the IC's.

Do you REALLY believe heatspreaders give cooler module surface temps compared to naked modules????
:stick:

Well, I've toned down my rant as I am now a more calm, collected person. I was just hacked off at the time and today I'll start giving individual sticks a go.

anywayz, my specs:

2500XP-m (capable of 2.8Ghz, ran no higher than 2.5 whilst testing)

DFI Infinity (4/29 & 1/21 bios used)

Raddy 9800pro (kept at stock speeds for testing)

Antec TC550 (+3.3v @ 3.7v)

Audigy 2.

Entire system cooled by airconditioning! Nbridge cooler replaced with Vantec Iceberq.

CPU Voltage: ran no higher than 1.9 volts whilst testing.

CPU temp: went no higher than 18 degrees at any point.

Board voltage: tried all from Auto to 1.9

Board temp: Went no higher than 20 degrees at any point.

Vagp: Tried 'em all.

I've lumped the whole lot above together because they did not seem to help the situation for better or worse, I was also using my CPU and AGP well within (my) spec to eliminate their effect.

for most test I used a multiplier of 10, occasionally I used 10.5 and 11 just to check it wasn't the 10 multi causing problems as I never use it.

Other stuff:

All onboard stuff turned off (with the exception of IDE/floppy)

CPU interface: aggressive
Ram speeds: tried turbo, aggressive, optimal and expert.

I found that the Ram lasted longest at the "optimal" timings, "turbo" would boot but would not last long

Raising vdimm seemed to allow the ram to last a little bit longer but did not seem like a solution. The inside of my case is extremely cold and the heat jackets do not even get warm (Edit: infact, they are cold) to the touch. I've tried voltages upto 3.1v so far. I will try 3.2 or 3.3 if I get an okay on that.

I tried some Expert timings too:

I tried 11-2-2-2-2.5-13-15-*e-a-f*-CPC on

I tried 8-2-2-2-2.5 etc...

I tried 11-3-3-2-2.5 etc...

I tried 8-3-3-2-2.5 etc....

I also tried the extended beta timings at 2 -(all the threes)- 4 and Auto

Edit: I also tried all the above at Cas 3

At stock speed and turbo settings it seems fairly stable in windows and can run 3d for about 10-20 minutes before locking up or falling back to desktop. At higher speeds, system errors become more apparent and further still give hardlocks or re-starts. At 233fsb (x10) with 8-2-2-2-2.5 (3.0v iirc) I even got a crash while running the Sandra memory benchmark.

Up until now I've been running in slots 2 & 3, I'll try 1 & 3 today.

I have moved recently and was worried that my rig was throwing a wobbler at being disturbed and moved across country. So I threw my known good sticks of CH-5 3500 EL in and BAM! everything is fine. I know that I had issues with BH-5 LE 3500 on my Dfi, but didn't a few other people? :p:

again, sorry for ranting last night. I'd had a pretty tough day and I was kind of drained after the anticipation of this EBs performance left me disappointed. I'm going to try some more stuff today and see how I get on.

Edit: Just did some more testing and found a slight improvement using slots 1 & 3 (strange - the EL only likes 2 & 3) and found a bigger improvement using single channel.

I tried running prime in DC and got a rounding error almost immediatley.

What I did find though is that using a multi of 6 seemed to give a big improvement. This is odd as I can produce stable benches at 233 x 12 with the EL repeatedley. To doubly make sure my house is in order I am going to reseat my heatsink with some fresh AS5, just in case It got disturbed on the ride home. While I'm at it I'll do the 200fsb L12 mod as RGone at Amdmb found this brought stability with high bus speeds and multipliers.

Can someone move this to the correct forum? I posted it in the wrong one in my frustration last night.

hope to see all go well cactus.

funny but I had the reverse problem last night. Put together a system with an A64 and K8Npro and none of my 2x512's of ram would let me overclock until I put the EB in. Must be something with the 512 bh-5 sticks maybe. Anyway works like a charm now with the 2x512 of pc3200 EB!

Cactus, what worries me a bit are some of the issues you are seeing with respect to a single DIMM being more stable and the position of the DIMMs making a big difference as well as that you are getting better results with the lower multiplier.

To me this sounds a bit like a controller issue, either hardware related or else cooling / voltage. I know that if I increase the chipset or AGP voltage on my box, it gets very unstable immediately.

There is one difference between the CH5 and the other chips, which is the tRCD that you can only run at 3 on those (you can actually set the write tRCD to 2). tRCD is a bit of a funky latency in that the controller sometimes does not differentiate between the command latency and the RCD and throws both of them in the same pot (with respect to when the chipset expects the data back from the memory). Another issue could be the BIOS version you are running.

They have messed around with the BIOS so much that nobody really knows what is happening anymore. One example is the reduced command rate (CPC) that also impacts the arbitration between the memory channels and I've been talking to Oscar quite a bit on these issues and what other latencies they had to increase internally to get it to work ... Among those was the RCD (again)

In any case and FYI, I am playing with mine again and what can I say (everything at auto voltage except for memory at 2.8V)

OCZ I AM REALLY SORRY FOR DISSING YOU

I have just made a significant discovery with my hardware combination and this RAM.

This afternoon I resat my sink with some fresh paste and while I was at it, I did the 200fsb wire trick.

As I type (on my Laptop), my system is looping 3Dmark at 11x233 with 8-2-2-2-2.5-13-15 timings with CPC on in DC.

It seems that the L12 trick is crucial for the mobile processors with an NF2 and this new ram which is bizzare considering I was able to get my CH-5 so high with the unmodded chip.

I sincerely apologise for jumping to conclusions, I've been under a fair amount of stress lately with moving home and changing jobs etc. I souldn't have blown off like I did last night. I do however think that I've made a significant discovery with respect to this hardware combination and I hope it helps all you OCZguys and DFI/mobilers/NF2 owners in the future.

Now to go break some records!:banana:

:thumbsup:

it's amazing what a little 3cm piece of phone wire in your cpu socket will do :D

I've had the same problem with my mobile. Until I did the L12 mod I couldn't run higher than 225fsb. Now I am trying to find the ceiling. Seems a little conductive paint works wonders.

interesting.

Hmmm.... this is weard.. Do you think L12 helps on Dfi LanParty with mobile cpu?. I have not seen that problem with my mobile xp2400+ 35W. I runing @ 258.9fsb 24/7without problems and i have runed @ 280fsb+ without problem and i have not L12 modded my cpu...


One more thing do you have 2x512 PC3200 EB or?, Use this setting in bios (Cpu Interface:Optimal) if your usb are looking,sound and more. And try 3.3vdimm and see how high you can go. And try 8-2-2-2-2.5-9-12 and 11-2-2-2-2.5-9-12

All is good Cactus Jack. Thanks for the info. I will buy a mobile barton and check this out first hand.

Tha main thing is that you are working and working well. I used memtest86+ to set up my RAM timings. Watch the memory bandwidth results. Change your tmings to 2.5-2-2-10 / 12-14 and see if your bandwidth is higher than wfat you have. Bigtoe and I found different settings that worked best on the DFI NFII B, so experiment with 8,9,10,11 and 11-13, 12-14, 13-15 (always 2 numbers apart), You will find a combo that will have "fine tuned" your EB RAM to it's peak.

Have fun dude!

Ah yes, keep a fan on the RAM, with mucho volts the heat spreaders really draw off the heat.

LV, you aren't using EB (mine is 3500 btw). When I was using EL3500 I was able to go upto 233 without any mods. It was only when I tried the EB and got totally frustrated that I ended up doing the wire trick which solved my problems.

I tried doing some runs at 243, but it didn't quite hold together. Does this ram benefit from burning in?

Andy, the heat jackets are cold inside my case, it helps a lot when the air temperature is at 4 degrees C inside my case.;)

I'm going to try a couple of different bioses (using the 4/29 right now and see what that gets me.

I know what memmory i´m using lol.. But i cant belive why the L12 modd make a difrents on sticks to sticks "bh5 to EB". But maybe we will figure it out know :)

I don't know how it worked either, but it did. ;)

It is weird how i didn't have this issue with my CH-5.

Ok Jack, glad to see it's working better today, Yes 4c in your case is a good thing.

The bios issues are manifold as you know. Some of the bios' Oskar created won't run test 5 in memtest86 at all. I would try the 12/31 beta. I had the best luck with that one overall. I reviewed my NFII B using that one and never had one issue. I have not tested the EB yet with that bios. I am not at the facility with my DFI right now, but will be by next weekend. Let us know how the bios search goes, and what works best for you.

You might have said, but is this a 1gb kit of EB? Also is your CH5 a 512mb kit?

Let us know what sizes they are, as this might help all of us out.

Thanks

The EL 3500 is a 2 x 512 kit, that clocks quite nice for CH-5. I initially bought a 2 x 256 kit of LE 3500 for benching purposes when I ran into the well documented compatability issues of late BH-5 and late NF2s. Tony sorted me out with an RMA for a 2 x 256 kit of EB and I guess you can follow the rest, lol. I'll give the 12/31 a try in due course. I'll need to try another bios as there is still some instability at above 243 fsb, unless I resort to looser timings. I'll get some more testing done tomorrow, did any of you OCZ blokeys try burning this stuff in for any gains?

I'd like this Ram to get close to 250fsb while still holding reasonable timings. I'd need to get that high to see any benefit.

Hey pal :D

The L12 mod gained me stability with my 1700+ tbred too... at least at 9x262 :D

I had random reboots without it and sometimes could not even boot into windows...

Update:

I'm still trying to find my stable ram overclock, but at least this time I can see when things are failing rather than just having to deal with a totally ballsed up system.

I managed a run at 11.5 x 243 at 10-2-2-2-2.5-12-14 on the 12/31 bios but it seems to kill off some of the 3d performance. I was going to flash to the 1/21 bios and then try the 2/15 but I think my hard drive has got corrupted, so I'm doing a repair right now and will try some more later.

I managed to get to desktop at 250 using 10-2-2-2-2.5-12-14 (using *cough* *cough* volts) and clockgend to 253. I managed a couple of test of 3Dmark but unfortunatley it froze.

I'll be glad when I find the sweet spot, but it'll require a fsb/multi combo that will allow me to take advantage of the 2.8Ghz my moby can run at. So untill then it's all juggling apples and oranges til then.

p.s. I started a thread informing peeps of what I found at Amdmb in the DFI forum, there has already been one person come forward experiencing the symptoms I described.

cactus, i too am experiencing those same problems..
but im using a normal XP2500, NF7, and 2x512

217 2.5-2-2-8 3v reboots during the second run of sandra mem
217 2.5-3-2-8 3v failed prime blend after 5mins

i am hoping there is an initial period where these sticks like to just stuff up completely, then once this has passed they perform like they should

I don't think that was the case with me. Before I did the 200fsb wire trick, these sticks were unworkable at any reasonable speed or any reasonable multi. After the wire mod I was looping 3Dmark at 233x11 for well over an hour.

I can only hypothesise that the patented "EB" system must alter the way that the sticks communicate with the memory controller and we all know that Nforce2 chipsets have some quirks. I'm sure that the OCZ blokeys will be able to give us a more complete answer in due course.
