OCZ 3200 EL Plat Rev2 + CAS2.5 = No Go?

Hey guys, I have some 3200 EL plat rev2 that decided to go wacky on me recently. For the past 7 months it has served me well giving great timmings and good clocks, but in the past few days it decided to loose its mind.

My Setup: the and is for when i switched out components during troubleshooting
DFI nF4 Ultra-D or MSI K8N Neo2
3000+ Venice or 3000+ Winnie
OCZ VX4000 or OCZ 3200 EL Plat
X700 and/or PCI video card
OCZ 520Watt

The Problem:
The memory ONLY wants to work at CAS 2. If i select any other setting than CAS2 it will not work in windows. If i try to boot up in anything but CAS2 it will just BSOD before its done loading into windows. Any other timming will work fine with the memory, just not the CAS latency. Whats even odder is that hte memory runs great at 275mhz with karakato timmings in memtest. Tested in memtest for appx 20minutes of test 5 with no issues and let it go through the full test once.


My Testing
To weed out any other factors I tested the memory in various setups. Here are the differnt setups I used

DFI mobo w/Venice CPU and X700
DFI mobo w/Winnie CPU and X700
MSI Mobo w/Venice CPU and PCI video
MSI mobo w/Winnie CPU and PCI Video

I also ran my VX memory in both of these setups at hte same settings as the TCCD 200mhz 2-3-3-7 and it worked fine at 2.85 volts. To make sure hte cpu and mobos would do 2.5CAS i tested all the above setups at cas 2.5 with the VX and it passed every time.

wtf so you have some crazy tccd or something but i think its another problem

i would reflash your bios on your dfi maybe and see whats up.

got any friends with a computer you can try them in??

what about trying them one at a time??
________
Vaporizers

sure its tccd?

Burnt out IC's? :confused:

rma time it sounds like...but just to see try running higher voltages like 3.4v and tight timing like 2-2-2-5 or so and see how high they will go for :banana::banana::banana::banana:s and giggles! let us know!

I've had the same experience and found out how it happened at least for me. Had 2 sets of OCZ EL Platinum Rev.2 and both of them went strange as yours.

My ansawer is that if you play with high voltages(above 3.3~3.4) for some period of time, they start to loose their minds, and CL 2.5 or more(loosened) won't work anymore. Only works with CL2.

Remeber when there were Rev.2 TCCD sticks that liked high voltages? At that time I thought mine would like them, too, so started putting in like 3.3, 3.4, and 3.5v. When I played with 3.5v for like a few hours, it suddenly couldn't start taking CL2.5.

So I tested another pair of the OCZ EL Platinum Rev.2 pairs, and played with high voltages, and the same thing happens again.

I'm not sure what's the exact reason, but the above is what happened to me. ;)

Maxxx if you have been running them at 2.9v or higher you have wacked them. TCCD is very sensitive to voltages. I see people running at high Vdimm with them for short periods but long term it will damage them.

Major 2.85 is the highest I have ever gone with them. I think i might have booted them up at 2.9 once or twice, but I never went over the warrantied voltage.

Its garunteed the memory. Like i said, tested with two cpus and two different motherboards. reread the first post and ull see that i mentioned that in detail.

LOL. Im sure its TCCD.

Here is something funny though. With my Neo2, i just tested the TCCD again. at 2-3-3-7 at 245mhz the darn stick is rock solid. I should note I was running single chanel with one stick of 512, but you have to admit 1T at 245mhz CAS2 is REALLY wierd and really freaky. I will post a SS when I can get it off that computer.

How old are the modules, did they come from older stock at a store?

We did have an issue a long while ago with some modules not liking anything apart from cas2

I Have this exact issue with my Patriot XblK for a couple weeks, wont boot with cas 2.5 or cas3 in any FSB, even 200mhz. In cas 2 i can reach 250 mhz 2-3-3-5 3.1V prime 5 hrs Ok. Before i reach 280 mhz in cas 2.5.
¿why is this? i am worried that the memory finally dont work even in cas2. :(
Please help.

It usually happens when you play with high voltages. Anyways, I'm pretty sure your sticks are damaged permanantly so should either look for an another one or see if you can RMA them.

My friend have same problem with Tccd week 49 , running fine with cas2 , but cas 2.5 and 3 is no go

Which week doesn't really matter. ;)
TCCD are very sensitive stuff, and it happens when they are damaged.

Tony, they were bought in december 2004, but they ran in my neo2 for months on end at cas2.5 with no issues. Also tested them in my NF7-S briefly and they ran great there too.

As to the voltage. As I have said, I NEVER pushed these dimms past 2.85~2.9. Most assuredly I know that TCCD does not like higher volts and hence I NEVER pushed them with higher volts. Even when there was that TCCD loves volts craze I never went above 2.85.

But, 3.1V isnt a very high voltage, the question is, if the memory is damaged why run fine in cas2?

3.1 is way high for TCCD...

Maybe, but less voltage got errors in memtest.. :confused:

Ok, I was able to do 310 in memtest on one stick and 300 on the other.

here are two screenshots of the testing I did. its sad really as they are very good sticks.

I had the same thing happen to a set of tcc5..

200htt 5-2-2-2 worked fine..

200htt 5-2-2-2.5 bsod'd..

They just didnt wana run cas2.5 @ ANY speed..

My old Gskill LE's would BSOD with CAS 2.5 at anything under ~250 FSB but would run fine at 250+ CAS 2.5. They did 260 2-3-3 and 310 2.5-3-3. Weird I know but what can I say.:)

How do you fix the cas 2.5 problem?

He was running at single channel, may be that was the fix.

no that wasnt a fix. it would run dual cahnnel in memtest too.

I just wanted to test out each stick to make sure if it was both that were borked or just one. Its really a pitty too as these are some GREAT sticks as you can see from the memtest.


On a side note i got the system to boot with one stick at 300mhz 2.4-4-4-8 but it wasnt stable at all. rebooted at slower speed (280) and it just crashed instnatly.

Dual channel, DDR 600 at 2.5-4-4-8? sorry I thought that you were having problem with this RAM running other than CAS 2.0?

I will need to go back to your problem more closer then, sorry.

Yes I am. It will ONLY run memtest at CAS 2.5.. It wont get into windows. Windows is only stable with CAS2.

I wont even boot in cas 2.5, i think isnt the same problem. :confused:

it IS the same problem. bamboo didnt understand though.

Yeah, my bad.

Form my experiences with DOS version Memtest (not actually DOS version, just sort of anyway), it is ok for pre-screening the RAM's stability, if the RAM failed, the chance to boot Windows will be very low. If paseed, no guarantee the success to Windows, though.

I have a pair of G.Skill GBGH, can do memtest all passed, DDR424, 2-2-2-5, 3.1V, DRAM drive stength from 3-8, but for any value higher than 4, BSOD for sure, 100%.

I am running the OCZ Platinum Rev. 2 right now as well, on DFI Ultra-D, OCZ 520W PSU, at FSB 280, 2.5-4-3-5, Vdimm 2.51V, doing OK. May be it is time for RMA.

Issue is maxxxracer has modules that need a new SPD, nothing more.

SPD is dead... now that is wierd. tony you have any idea how exactly the SPD can die like that?

Its not dead, you just need a reprogram thats all.

oh cool. so you guys are jsut gonna reprogram it for me? Sounds good. Time for some 1:1 2.5-3-3-7 action.

lol dont thing so ^^^^

how do you go about re-programming it though?!?

I guess bigtoe is the OCZ tech team, for a company like that, they do have machine to program the SPD.

I think I have the same problem with my Geil Ultra X TCCD.

They don't do cas 2,5 timings anymore, only cas 2. I can boot into windows with cas 2,5 but get an automatic reboot.
I have been trying 2,92-3,1vdimm , which wasn't a great idea so it seems.

Is this fixable with an SPD reprogram?

too bad , they did 275 2,5-3-3 or 285 2,5-4-3.
Currently running at 2-3-3-6 238Mhz

I have a very similar problem with my Plat rev.2.

In the past the ram ran at 300mhz 2.5-4-3-6 at 2.9V full stable.

Currently they only run at 267mhz 2.5-4-3-6.... but at 2-3-3-6 is stable at equals mhz, and in single chanel one stick can do 300 2.5-4-3-6 and the other 332 2.5-4-3-6..

SPD reprogram could be the solution??

Hi!
I have the same problem. cas 2.5 is no go. OCZ platinium R2 3200
I used to run 2.5-4-3-7 320MHz 3.0V.
Now its only stable at cas 2.

I really do think you have TCC5 Max...as it tends to scale higher on cas 2.

So if i understand the problem correctly, single sticks work fine at 2.5...but in dc the dont ?

Perkam

I bought 2x512 Adata PC4800 used, and they seem to have the same problem.. Anything above cas 2 will make it fail, so I can only run 2-3-3-5 @235MHz.. I dont know how much vdimm the former used featet it with though..
I can get it stable in Dos based memtest86 for hours at minimum 2.5-3-3-7 @270 2.8v vdimm. In windows it wail reboot at any speed as long as I dont use cas 2.

So I guess I have exactly the same problem as u guys have.. I may send em to RMA then. Or if I can get a reprogram it would be nice!

guys,
test your TCCD sticks individually , single channel.
In my case, only one stick went bad. the other one is still ok , 290Mhz 2,5-3-3-6

I also have this issue

I can run either stick at cas 2.5 individually, but putting them in together wont work. I cant even boot to anything, i get the first bios screen but not the second (showing device IRQs etc) and thus cant boot to windows/memtest.

sounds like if they have to be sent back to OCZ i have little chance here in australia

edit: testing 240 2-3-3-7 at the moment. Wish i had tried this before, its working fine :eek: my cpu max is around 2.5 anyway so 10x240 is good. If this is stable might try a bit higher but im reasonably happy for the moment :)
If there was some way i could get my ram reprogrammed anyway that'd be good, but id rather not have to send my ram internationally to do it.

Same issue here. I think my sticks work in single channel in 2.5 but definately not dual channel. When in dual channel at CAS 2.5 either it won't boot, or occasionally it will boot but blue-screen before reaching windows.


So what is the consensus on this? RMA? can it definately be fixed with just a reprogramming? MaxxRacer have you gotten this resolved? bigtoe - anything?

List your config so we may have a look see if there is something else going wrong

For the long explanation, see this thread:
http://www.ocforums.com/showthread.php?t=407319

For a summary:
PC-DL with (2) 2.4 xeons at 3ghz (known stable up to 3.4)
fortron 550w power supply
nothing else important


Two sticks of the OCZ 3200 Plat Rev2 run fine in single/dual channel at 2225, and I believe run fine in single channel 2.5-3-3-7 but not dual channel CAS 2.5

I have memtested each stick individually at default (200, 2225, 2.7 volts) and passed 7+ hours and 40 passes just fine, and also passes dual channel memtest and prime95 testing in windows.

When I attempt both sticks at CAS 2.5 it won't boot, or maybe will boot once in 10 tries but blue-screen before windows.


I swapped the memory quickly to my NCCH-DL and it showed the same symptoms, booted fine into windows apparently stable at 2225, restart -> bios -> change CAS to 2.5 -> save are restart -> no boot.

Pop me an email m8, lets you get sorted out ;)

Email sent. Thanks for the quick help.

I have the same symptoms, i can even run at 240mhz 2-3-3-7, but 2.5-3-3-7 at 200 is no go.
Can run the sticks individually at 2.5-3-3-7 single channel fine, just not together in DC.

Bigtoe can you give some advice as to what i can do, given that im in australia?

I got the rma and everything, but UPS decided to be the morons they are today and not deliver the package and now it says it is delivered somwhere else..

tony, can you guys start using fedex.. UPS is the worst service to ever exist on the face of the planet..

Maxxracer, u have exactly the same pb which i've experienced by using DFI Ultra-D.

My old Adata TCCD (week 49) goes well with cas 2.5 on MSI Neo2 but since i change to DFI UltraD the same pb was happened.

My comp refuse to boot if CAS setting is other than 1.5 or 2. In fact in memetest they do 310 2.5-3-3-7@2.7v but to boot in to Windows they needed at least 3.1v. I mean everything was fine before using DFI NF4. If u have a chance to have another TCCD kit, u'd better use them with your MSI then your TCCD would run correctly. But if u let they go with DFI NF4 first then the same pb will occured.

Here are some intersting scr of my Adata

@3.2v

I think I have neven seen TCCD @ 275 Mhz 2-3-3-6 (1.5 in this case)... !!!

And also the voltage is extremely high for TCCD! Are you rock solid @ 3,3V 1.5-3-3-6 @ 275 Mhz?

Really strange behaviour for TCCDs.


Are you sure they are not Hynix B? Do they boot @ 200 Mhz 2-2-2-5 (if yes, they are TCCD) or could you please paste the P\N?

http://img240.exs.cx/img240/1797/tccd4vg.jpg ;)

No @275 is just for bench, but it is still rock @265@3.3v

For 2225@200Mhz they only need 2.6v.

Pumbaa, they didnt work with the MSI either..

on a side note i got my memory back from RMA, but it was thew newer PC4800.. but im having nasty issues with it. apparently it doesnt want to memtest above 295mhz despite using ANY timmings. this really does blow. and it isnt stable in windows at 295.. im at 280 right now and this really blows.

My old tccd would do 315 and 310... tony even told hte RMA guys to just reprogram the spd.. i guess they ignored that or that the mem was more fried than we had suspected.

hi all,

i'm facing the same problem after setting at 3.2V @2-2-2-5 @ 215Mhz
at my dfi board...

so, should i rma it?
or juz keep it?

u have 3200 el plat..?? if so.. well u fried ur dimms... the warranty only goes to 2.9volts, and 3.2v is WAY over the warrantied limit.

No...
what i get is a corsair...

well you should NOT RMA it as you voided the warranty, and doing so (RMA'ing it) is fraud and subject to legal penalty.

Same thing just happened to me the other day actually. Would even go into Windows at anything other than CAS 2.0. RMA came a couple days ago and they sent some with the new TCC5 chips. They won't go over about 240-245. Bummer. :(

charlie

i'm not going to rma it...
since juz know that my ram, original timing 3-3-3-8, got so many revision
even get a rma sucess won't be getting the same chip again...

going for a pair of new tccd
anyways, thanks for advice...

for all who face the same problems, mind you all telling me what revision is your dfi board?
Does it revision A03?

mine's A02

Ive had some funnies with my TCCD. When i first bought them they would do 280MHz 2.5-3-3-8 @ 2.7V. Over time their speed has degraded. Their best now (after 6 month) is 260MHz 2.5-3-3-8 @ 2.85V. :(

I have OCZ Rev 2 strange thing is mine loves low volts mine errors at 2.7 yet at 2.6 it runs at all speeds. Strange stuff this TCCD, very glad mine like low voltage cos that's less heat to get rid of :-))))

oh wow I'm not alone with this problem. I have the same exact problem as the maxxracer, my ocz plat rev 2 refuses to run cas 2.5 even at 180mhz. It can memtest at cas 2.5 till 270mhz easy but it will not enter windows. I was running 270mhz 2.8v 2.5-3-3-7 for 2 months straight, then 1 day while gaming the system bsoded and it would not run cas 2.5 again.

now i run the ram at 240mhz 2-3-3-7
Is there a known fix for this(yet)? my motherboard is a dfi nf4 ultra

thanks for anyhelp

no fix.. have to RMA. if your lucky you will get PC4800 Elite plat like I did. These sticks do 307 @ 2.5-3-3-6. They will do more, but the mem controller cant take it.

I had this happen to me too for some very strange reason. However I did manage to get the sticks to work at cl2.5! But it was only very temporary. I had some crappy TCCC sticks that had a default of 2.5-4-4-8 @ 200MHz so I threw those in (set everything to default in terms of timings and voltage), they booted just fine. I took them out and threw the OCZ sticks in (TCC5) and they worked of course at 2-2-2. I set the cl to 2.5.. and guess what? That worked too. It worked fine at 2.5 until I changed the other timings, then changed the cl back to 2 again, and then 2.5 would no longer work...

TCCD/TCC5 has to be the strangest memory to ever be introduced to the computer industry.
