what does PCS die mean?
Hello!
I have few comments:
1. Infineon CE-5 have the same specific - they have a frequency, over which relaxing of timings do nothing. But I don't tested they over 2.8-2.9V anytime, because voltage do nothing for them.
2. I saw TwinMOS on winbond chips in few latest weeks - they are on the cheapest modules. But they are not very good - from maybe 50 pieces the best works at 225-230MHz 2-2-2 @3V in memtest86. Of course they like voltage like typical Winbonds.
3. Who will check what chips are under the VX's heatsinks? Winbonds are very easy to recognize...
P.S. maybe a title of this topic should be: 'OCZ VX, winbonds again'?
PCS is a make...a manufacturer.
Speed binning of VX ensure every module does at least 240fsb 2-2-2.
Oh, k that makes sense. Unless Winbond err infineon makes tested chips rated at PC3200 with specific timeings it is much more worth it to just buy VX, since those are actually tested and will perform good.
Only AMD though right?Quote:

bigtoe, ryangroovey...
how about making a PC3500 VX or a PC3700 VX that is still rated at 2-2-2 @ 3.2v?
I know both my modules do over 250 2-2-2 @ 3.2v.... sure the price could be higher to account for the extra labour, but I'm certain they would sell just as well as the current brew
I have tested almost all bios on MSI K8N Neo2 + FX55 and my VX does max 230/235 2-2-2-5 1:1 (3,5 to 3,7V) 1T DC
What´s wrong????? or... where are the good ones??? :)
tried another CPU?
Guaranteed 240 @ 2-2-2. I love you OCZ ;)
Why another cpu? My mushkin Level2 (BH5) 2x256 do 280 1,5-2-2-5 with same cpu....
problem cannot be cpu or system.....
2x256 & 2x512 are not the same... maybe your memory controller has an issue with 2x512 setups.
maybe it is the RAM too, but it would pay to try another CPU to see if the memory all of a sudden goes higher....
2x256 is a big difference on A64 than 2x512 no?? i dunno if its that significant but still.
Edit: damn rabbi u beat me to it by some seconds :D
hehehehe 2 voices are better than oneQuote:

Don't believe it´s cpu or mem controller. I have tested 2x512 OCZ 4200 and got stable 295 1:1 2,5-3-3-6 1T DC (there are screens in this forum)
So my setup sure likes 2x512 :)
may be I was unlucky or the mems are not that good.... :(
hmm contact someone from OCZ for some help
Is it ok to run the VX at 1.5-2-2-10. CPU-Z doesn't report the 1.5, but i know it's not accurate for stuff.
I ran 3dmark fine, is it woth keeping it at that or 2?
Run benches at 2 and 1.5 and find out yourself. :p:
Check the official test thread. Rabbi_NZ runs his at 1.5-2-2-10. CPU-Z doesn't report CAS1.5, but it doesn't negate the fact that it's running at that latency value.Quote:

Guys we test at 240fsb on the Neo2. The modules seem to not do as well on Intel rigs although WXchaser hit 260 with 3-2-2 and I hit 250 on the 875P-T with 2-2-2 so they do perform as long as the board does.
We have no plans to release them at 3700 speed as this may drive price up, (things do change though)
We are doing our best to keep prices as keen as we can with the extra testing involved...im sure you understand.
I know I do. I'm just dying to get a new board to really push these things. I need to sell off one my kits for cash. Whichever does worse. Buying 2 gigs of ram broke me.
oj, people usually benefited from burn in
LOL @ letter
Agreeeeeeeed :banana:Quote:

Q: what is the best performance setting,is it 10x224,9x230 or 8x231,its now running at 10x224 at 3.40vdimm and prime stable.
Rocker, what is your VCore?
10x224 will smoke your other scores!
Vcore is 1.550/104% so something like +-1.62v.
And what woot be the best setting to burn'in the mem,becaus 10x224 isnt that great hè.
When it just got them the hit 10x250 at 3.40vdimm and 265 at 3.50vdimm,what is the matter with this mem :confused: .
Should be enough....
Could you list:
*ALL your memory timings
*ALL voltage settings
*ALL multis & dividers
*Is you CPU a CO or CG stepping
*What slot is RAM in
The a64 rig is not connected to inet,but i will make sreenshot of a64Tweaker and post it here.
a64 3200+ Newcastle
ADA 3200 AEP4AX
CBAEC 0430 RPMW
1 stick 512mb VX
its running at 1T 10x224 at 2-2-2-10-15-16,mem is in slot 2 at the moment,before it was in slot 1 also in slot 3 and i had the same results.
vcore 1.550v 104%
vdimm 3.40v
chipset 1.6v
No AGP becaus a use a pci TNT2 32mb.
Multies or dividers:its running 1/1 that is the only one am intrested in.
But i am gone try my bh5 to see if the can hit higher,and to see if the board is still ok or not i hit 9x275 with my corsairs on the dfi.
RocKer,
I just remembered!
wait for Conrad to come back online... from his testing he found his NC would not run in SC with VX, but in DC it would run fine.
My CH was fine with either configuration...
OK
But what i dont understand is that this VX stick did run at 9x265 3.5vdimm the first week i got it in the house,and now i can only hit 9x230 :( at 3.6vdimm,i dont understand it anymore.
I can only do SC Rabbi_NZ ;).Quote:

How's your PSU?
Maybe your voltages go down too much?
Yo RocKer. Check this out. What motherboard are you using? If you're using an MSI K8N Neo2 Platinum, see what happens if you run dual channel.Quote:

When I hit a wall, I'll loop Memtest overnight at my last error-free frequency.
well - this letter is more then funny... :wierd:
M.tec is TwinMOS low-cost brand - there could be every IC underneath... but of course cheepest IC out there (which atm is also Winbond UTT) used and as you can see it can perform as good as the VX
Winbond is not dead... they have a deal with Infineon to use Infineons Technology for the new production - on the other side with this agreement they are not allowed to put Winbond Label on the ICs - afaik...
bump, can someone answer my question in bold?Quote:

When it was at 9x265 3.5vdimm it run test5 for +- 2hours with 0 errors,then it folded D2OL for 3day's and 2 nights 24/7,thats 100% cpu-load,if thats not stressed enough i dont know what will:),and to be sure i run +- 2 hours prime ontop of D2OL and that was also rock solid stable.Quote:

O yes the test where run all at 2-2-2-10 or 2-2-2-5.
My 520w OCZPowerstream works ok.
I still have to try my 2x256mb bh5 to see if the can run as before(the did 9x275 error free :) )did'nt have the time to do it yet,but if i find time today i will try them.
Can you give some info on what to do to burn'in the mem and easy go up with htt,or something becaus i dont know what to do anymore :( ,it was looking so good the first week but sadly it did'nt last.
So now am wondering if the dfi(again) is to blaam or cpu or the memory,i can't try it on an other board becaus i dont have an other s754 board.
I'am now serious begin to consider to quit s754(sell it or make it a D2OL rig) and go over to s939 in DC.
I have got no luck yet with a64 on s754,it was my first one,it was allways something that whent wrong,almost everything is gone in rma,first it was the DFI then cpu then the OCZ 520w,and what is it now ppffff.
@ ryan
so can you say that u use new winbond (of course selected) IC for the VX?
u r absolutely right M.tec can be everything - Winbond, PSC, ...
but new (not the ones out on market atm which are selected PSC) TwinMOS Speed Premium which will be out soon will all come with these new Winbond IC.
Alonso
FAE TwinMOS Germany ;)
Have u done any testing on those? What can we expect?Quote:

VERY OFFTOPIC !!! :eek:Quote:

Seriusly though, crucial just selects them better for the reviews not the consumers :D
Perkam
Funny, I have some SuperTalent memory that acts a lot like VX. Hrmmmz I wonder what is under the spreaders.
Couple things I'd like to note though for all you looking for a cheap way to get the same ICs as VX. First as we have seen from the countless TCCD reviews the OCZ/PDP/PQI modules always seem to work better because of the better PCB design. Much the same will come from buying cheap modules with the same ICs. The OCZ VX will just work better due to the better PCB design.
hey...whats going on here?!?!? I NEVER wrote the part in bold...Why is someone changing my posts???Quote:

not yet, still playing around. I was able to get it to 280 2,2,2,5 but frozen on screen shot
is it possible that vx is tccd 437(week 37 and up)?
^sometimes the week 37+ TCCD's didnt like voltage
in was inconsistent
I have a question. Should I run memtest86 with default #7 test? or I need to run #5 only since lota ppl preferring it?
Thanks in advance
I would clear the #5 first than go #7. If I have time I would run all test but these 2 usually tells me if I am going to hit wall or not.
I left it with #7 for 2 hours(about 8 passes) and no errors, should I move on to #5 now?
Sure sounds good :) After all that is done, I suggest testing it with windows memtest as well. Even the ones that pass memtest 86 have tendency to fail on windows memtest especially on A64,
Yes that's true. At the very first time there were more than 4 errors within 10% but now seems fine with about 2000%
And one thing that is confusing me, why my OCCT CPU toture failed at 250x10 before I went for memtest86 and now it could last for 1 hr + now? is there something to do with the on die memo controller or just about the memory?(I quit the program since I had to order pizza online)
Thanks for getting back to me Jinu117
There seems to be certain break in happening with VX from all reports I've seen. I don't know as i've only had about 1 hours tops on each VX chips I tried yet and more worried about divider atm. You might have to keep testing over time to see where your break in ends :)
Unless your mobo is brand new, I doubt it is mem controller or mobo that makes you able to fly now. Gotta be something with memory itself.
I need to ask you a favor :) Have you tried divider on memory and see if it causes you problem? Thanks in advance. Most of us seems to have problem over 260FSB once divider is set to 166.
Wow, is this stuff discontinued now????
MWave say's so on their site. I hope that's not the case :(
Only place I can find it is NCIX out of Canada for $281 US
Interesting... either Fry's sucked up all inventory dry or the memory batch isn't as good as it used to be to mass produce this. Or RMA rate is too high where it isn't worth selling the product. Think first one is valid if the deal wit Fry's went through.
it would suck if the vx was discontinued, i run my system at 260 and was looking forward to trying out a pair
i dont think it can be discontinued 1 month after its launch....
discontinued i hate this :( last time i decided to buy ocz 3700eb ordered it to a friend coming from usa he cant find 3700eb and get me a 3500eb now vx gone :( hey ocz people can you do rezervation for me at least for ddr booster i missed the vx train lol :D
How you cool the Memor at these voltages ?
Only the HS or a Fan (more) ?
you can just place a fan over the memory modules^^^^
EDIT: here is a thread on the topic
finally someone other than me who bought vx from mwave.Quote:

Now I just need to get an A64 and I'd be set :D
Extreme shortage of 3500+? Interesting. FYI, there will be 4 coming up for sale (3 winchester and 1 newcastle in few days). used less than 1 hour each :P For winchesters 1 boots no problem with -55c or below, 1 boots fine -55c above, 1 doesn't like -30c below. New castle hasn't arrived yet (monday) but I have feeling I am going all out FX-55 in few days anyway.
Check the FS section on CPU tuesday or wed :)
Gone already......glad I got some ordered from MWave on Wed. It's sitting in the Fedex dist. center, should have it Mon.Quote:

Prolly samsung will come out with another 'good' ones. As for vx, imo ocz already exhausted their chips that passed speed binning. Is this gonna be a trend? Released a batch of high perf. module, discontinued and move on.....
To Jinu117, no I haven't tried memo divider yet but I will do that for you. Last night I ran 288 passes #5 ot 250MHz and there's been 1 error per pass since loop 5x. And later I tried 255MHz and there were 20 error per pass average. So should I go back to 250MHz or stick on 255MHz and see what's gonna happen?
No this is not a new trend...the issue is we pre test ram and not all modules pass the test....we could just realease without pre testing but im sure you would all hate us within a few days.Quote:

Sorry, I didn't mean to make it sound so harsh, I was just trying to make sure that they weren't discontinued like everybody was saying.
OCZ is teh pone :banana:
It's true I'm not a good english writer, I don't want to be annoying but can you tell me what did you wrote, please... :(Quote:

its brings back a good feeling when i hear about the burn ins and voltage that i remeber from bh-5, its almost like winbond makes living chips that give you a big kiss when you push them ;)
though it is wierd how differently these react with low and high voltages then previous winbond designs...
i can only hope the increased sales of these IC's would inspire winbond/infineon to make some higher end IC's
VX is some special ram. I have mine running at 260 2-2-2-10-1t with 3.5v Tried up to 3.6v and saw nothing more. Still burning in. Trying for 270x10 as that is the sweet spot on my 3500+.
BTW OPP, nice to see your seal of approval on these. The OCZ guy's deserve it!:toast:
i will try to get vx and booster in a short time if i find a friend returning from usa
I hope you guys can now see why we chargle a little more for our modules. All are pretested, and backed by a lifetime warranty. We also have a growing team of forum whores who are here to look after you guys and answer all your questions...;)
So as you see we pretty much are the most hands on enthusiast based company there is...and we are pushing to bring you even more awesome products and customer service.
More VX is coming...you just need to keep your eyes out for stock as it sells out in mins on every site it is posted on.
yeah, this IS great piece of RAM! and actually, i don't think that $259 is expensive for such great performing sticks. i remember, when i first bought 1GB of Mushkin LvL (almost 2 years ago) i spend $310 on it and it performs far worse than OCZ VX i have here!
ATM, i'm flying @ DDR520 6-2-2-2.0 1T - something i could dream of with 2x512MB Mushkin LvL II.
excellent job on selectioning and pre-testing whatever ICs you guys found ;)
thanx guys,
However the prices in Europe are outrageous comparing with the ones in usa. Not only talking about ocz but for all.Quote:

Can sombody PM me when someone in UK sells them? ?
I wanna get some soon and I missed the gladiator selling them, they not sell 1gig anymore, only 512VX ram, but if i buy two 512sticks, I can run them in dual channel and there just like buying 1 gig (2x 512) ?
Neither do we. We just order them from online shops, pcmemoryupgrade for exampleQuote:

(Bios 1.3,1.36,1.37,1.4,1.41,1.51 doesn't fix this issue at all)
Let's see how it unfolds.
yeah, that divider issue really suxx.... i still believe it must be BIOS related / a way board handles VX...
OCZ really needs to look into it....
I never tryed a divider with this memory.Quote:

And yes, OPP. Would appreciate if you can find out if other boards such as Asus or s754 have same issues if you happen to have them handy :P Want to know if it is mobo issue, chipset issue, or bios issue, or something.

TBH you guys are going to want to run 1:1 as it is the fastest mode, don't go off buffered sandra use the unbuffered and use everest to compare..you will see what i mean.
but u see, the problem is that with divider issue this memory is useless for those that wish to run it in phase change systems... 256x10=2560MHz is OK with div 200 but e.g 285x9=2565MHz or 285x10=2850MHz with div 166 will be impossible.... :(Quote:

Mine will POST and go into windows at 275 on 200MHz (1:1) divider... will try divider and >280HTT tonight
Well sure enough, I just tryed the 166 divider on MSI Neo2. The system was all FUBAR after 270HTT:D.
I don't have other boards to mess with at the moment. Waiting on some NF-4 and ATI 480 boards next week.
I can see how some people with locked multis won't appreaciate the memory.
I myself am not worried about a divider issue for my rigs. 1:1 is my goal.
OPP
so in other words, if one's going for OCZ VX on phase change beyond 2900Mhz - better one gets himself FX.... :D hmmm.... that FX just got few places up on my "to-upgrade" list :)Quote:

If I get really nice batch of VX for this RMA... than maybe. 270 2-2-2-8 dual channel will be nice enough to consider it's fault (or mobo's fault) with divider and move on to FX. We are entering the first batch of 875p era kind of problem. (It was chaotic era with everyone scrambling to figure out what works and what not)
above 275mhz with the 166 divider i can't boot either.
also is my friend, too. guess everyone with the neo2 board may have the
same problem.
