Yea very nice! Tedy your ram seems to be doing good. I can't do 245 error free. Is that on your infinity? Is it actively cooled?
no 250 is fine @ 3.2 but 260 needs more time it is just the results ive gotten so far!
if it has a ^^ that means same voltage as b4. 258 and 260 are not good yet.
Bigtoe mentioned in another thread that the newer VX are doing better. He is getting some soon to test.
Thanks aCidbAbY, I have added your results and put you down as using a DFI nF3 754 board... let me know if I'm wrong.
cantankerous,
where did you read that... if these get much better we'll be seeing 270 2-2-2 on a regular basis :D
My Twinmos Speed Premium will do 257 in Dual Channel (socket 939) @ 3.3v... for now
MSI K8N Neo2 Platinum 0412 with bios 1.4 (official)
AMD Athlon64 3500+ Newcastle @ 10x257@ 1.6v for now... mem won't go higher @ 3.3v yet...
Twinmos Speed Premium week 48 2x512 @ DDR514 2-2-2-5
OCZ Powerstream 520W adjustable PSU
Thanks Garrett, are your chips 44D,50D,60D?
Oh I forgot I'm sorry... 44D :)Quote:

Time to cranck the 3.3V line of my Powerstream up a little more. :D
well my first set OCed to 260 at 3.56-3.6vdimmQuote:

LPUT 250 i will try and get some better numbers this time.
this is a newer batch and they seem to be clocking better at lower voltage...
I removed the heatspreaders from my OCZ VX last night, it would do 260 at 3.4v but after about 5 passes would start creating errors....
After removing the spreaders it's been looping over night without any errors!.... This stuff is great!
I think the next time I'll upgrade my memory is if any DDR comes out that can do 300HTT @ 2-2-2-5 (1T) :banana:
Maybe one day.... :D
So the DFI is compatible with the DDR Booster? I've been looking for this info for like 2 weeks :toast:Quote:

So removing the heatspreaders really does help eh? Must be a heat issue. Too bad you lose warranty from that. Heatspreaders should be an option.
Well the $h1t has hit the fan if you ask me :(Quote:

Putting my 2x256 BH5 back in results in no errors whatsoever...
If I try only 1 doublesided DIMM (doesn't matter which 1 of the 2) then I get no errors at all...
rabbi please correct
it's not SP but 2 sticks just happens to work DUAL too...hehe...
AA4T / 05034
i can do 25 loops with 1 stick at time at 3.3vdimm
will do some burn in at weekend.
Well,
After my earlier results, which looked promising, I'm kinda disappointed with the end result.
1*512MB
3.22V : 250Mhz (not to bad, IMO)
3.35V : 253Mhz (gained 1Mhz compared to last time)
3.46V : 255Mhz (not that impressive)
As you can see, increasing VDimm by 0.25V only gave me 5Mhz more, not that much after all.
Didn't have much time in testing the 2 sticks together, but managed to do 1, at 3.35V.
3.35V : 246Mhz (+1Mhz compared to last time.) Any higher would result in errors.
That's it for now. Results on the Neo2 might follow later (can't promise anything)
ok i tried to burn in at stock speeds and the 2-3-3-8 stock speed (200) errored out @ 3.2 vdimm.. WTF is up with these things?
then i went back to 2-2-2-10 and it was fine wierd it isnt running at stock speeds..
maybe because i burned in at 2-2-2-10?
new one BTW
200mhz @ 3.2vdimm 2-2-2-10
EDIT:: im thinking of getting another set and finding the best between the 2 :confused: do you guys think it is worth it? i mean this one seems to be acting wierd right off the bat. :confused:
Garrett,
try clearing CMOS and then loading optimised defaults... sounds like a timing has changed maybe
TEDY,
done :)
Jupiler,
updated yours too :)... sounds like it's your board/cpu holding you back right now
aCidbAbY,
standard timings are 2-3-3 @ 2.6v or 2-2-2 @ 3.2v.... no where does it say 3-3-3 timings as stock.
I dont think you need a new set though bro, yours are doing very good for not even being burned in yet... personally, I think it's your board/cpu causing the wierdness with CAS 3. If they work fine at 2-2-2 dont worry bout CAS 3 results... 256 @ 3.3v is above average I think and if sheeet does happen later on jus return them for an RMA
lol yeah i meant 2-3-3-8 sorry..
did you get the new one? 200mhz?
how long should i burnin?
also these new ones have OCZ in black on the side. my first set didnt have anything on the side just pressed into the heatsink..
Winbond chips never really liked to run at cas 3
I dont know much bout burnin to be honest... I have never seen a gain but I know of many who have, and I trust a lot of them. I've heard a few people say that 24-48hours is a good timeframe, then see if they have improved and burnin at the new speed.Quote:

SOrry jus to clearify... your modules WONT do 200 2-2-2 without at least 3.2v right?Quote:
no i am saying that the best i could do @ 200 2-2-2-10 is 3.2
yes sir
Same problem here, 2-2-2-5 3.1V isnt memtest stable. I can 3D bench and pi tho.Quote:

Either way though, I dont see you putting less than 3.2v into those badboys so it's really not important :toast:
Mine need at least 3.2 just to get going as well.
I've just received my VX replacements today and so far the results looks very promising, better than the first pair. The new pair just did 2 hours of memtest Test #5 and one hour of 3D Mark Lobby test at 255Mhz 2-2-2-5 3.5v (multimeter). I think I can squeeze out a few more Mhz out of this babies. My first pair can only do about 245Mhz 2-2-2-10 3.5v.....
wow, very good news. Did your first ones die?
I can't wait to get my new setup so I can see what mine can do. This is killing me being stuck on NF2 with crap results.
I experienced about the same.
After I finished benching, went back to normal settings (222*11). Knowing that they need volts, set VDimm at 3.0 and started the system.
I then noticed that it took a long time for the system to boot, until it suddenly froze.
Rebooted and increased vdimm to 3.1. Same thing happened, system felt sluggish and slow.
Took the sticks out, and put my Corsairs BH5 back in and rebooted.
System booted as normal, and felt quick and responsive again. Weird.
As you said, perhaps they need 3.2V to start with.
After running the first pair with 3.5v for nearly two weeks 24/7 (Folding), I began to experience frequent reboots and the frequency of reboots increases over time. When I tested the rams individually, one of the sticks have thousands of memtest errors, even at stock settings. The other stick has no problems at all.Quote:

Guys, as far as burning in your VX, the best way for you to do it, while charting to see if you are getting any gains, would be uwackme's BH-5 burnin.
http://www.dfi-street.com/forum/show...ackme+BH5+burn
Basically, you overvolt your RAM as high as you can, running it with 2-2-2 timings. You run the memory at a speed that is unstable, that causes errors in memtest86 test #5.
You run test #5 looped for ~6-12 hours, recording the number of errors that appear by the time the test period is over.
Then, you repeat the cycle for the exact same amount of time (~6-12 hours), at the same voltage, and unstable speed. You record the number of errors again.
After several cycles, you should see that the number of errors your memory causes starts to decrease (you record the number of errors, so you can chart, and see if your RAM is having any gains from the burnin process). Eventually, the errors may go away entirely.
Once you are getting <100 errors, boost the FSB up 1-2 MHz, and repeat the process.
This worked quite well for my BH-5, and gave me a good visualization of the gains that my memory was seeing, throughout the burn-in process. Worth a shot for you guys :)
Great thread by the way, an interesting read.
Cheers felinusz :toast:
I'll add uwackme's guide to the first post... I've actually read it a long time ago but forgot about it
ok, i think this is the best thread were to implement this Rabbi_NZ. :)
let's list our stick pcb aswell as oc results, to try to understand wich is the best pcb for UTT chips.
mine pcb is KO-6633 and btw i'm using TwinMOS DC kit (non SP) 50D with 0451 chips. (if i'm not mistaken)
PS: as OCZ VX has heatspreaders, it will be more dificult to do this for them. only some will be bold enought to take them off in order to see pcb rev... :p:
a copy-paste from my reply in the xtreme twinmos thread
tested my mem's today :)
# 1 : 261MHz
# 2 : 254MHz
# 3 : 240MHz
# 4 : 257MHz
# 5 : DOA
# 6 : 253MHz
3,65V, according to the multimeter
not too bad for out of the box, without burn in
pity one module is dead,
gonna rma that one with # 3...
next week burn-in :D
can I have module 1?
hehe
Rabbi, I already flashed to a newer bios, 1.51 but that didn't help either...
When I pop in my old trusted BH5 sticks the problems are gone.... looks like RMA time :(
I wanna test them elsewhere though, maybe it's my cpu messing about (memcontroller)
enok,
thanks enok I have added your info... if everyone else could do the same I will add all info we have here.
eventually I'll post requirements on the first post but I have little time now.
Jack,
thanks for that. how many loops of MEMTEST #5 did you do to get those figures?
Garrett,
try this...
clear CMOS, put UTT sticks in, go into BIOS and load optimised defaults, set timings to something like 2-2-2-10-12-15 and all the rest to how you usually have it, run memtest again.
you said sticks work individually but not together... are your BH5 2x256 or 2x512?
5 loopsQuote:

3.9V 265~?
same timings 2-2-2-5 1T
I found if I add volt during memtet86 bench will be more stable, e.g 265MHz 4 errors in 20 loops #5, no errors and superPi&3Dmark stable after 0.1V added
I stopped at 265MHz since booster is burning at 3.9V, maybe I can gain few more MHz but I won't hit 4V at all I mean isn't it scary?
I've been running 255MHz for few weeks, just upped my FSB up to 265MHz yesterday and system runs fine expect the massive heat
Pictures are horrible which were taken by my cam phone
Add: For every 2~3Mhz increasement I ran 20 loops #5 and #5~10 loops #7 plus 5 loops std test. If error free then jump on superPi and 3Dmark and Sandra etc
have anyone tried memtest86+ 1.50 ? :)
Marilyn, very impressive. That is what I hope my sticks can do! 265 is great. I would be happy with 260 anything over would be pure bliss.
What cooling are you using on those sticks as they must be scorching!
I haven't got any fan to blow on ram and booster. only 6 aluminium hs stuck on booster. partially cooled by xp90 and great f***king cold air in Canada you know it.
I will try 266+ later today if no go with 3.9V max then I'll give up and stick with 265
I live in Canada too but my house is warm!
No fan is crazy. I can't believe your ram isnt erroring due to that. I notice when my temps get up there I start to error.
Stuck with 265? I would kill to get that. You care to share an everest read, write and latency with us at those speeds?
My TwinMos 44D can't do 200 2-2-2-5 memtest at that setting :stick:Quote:

*It's Twinmos Speed Premium
MarilynMX - You've got an excellent set of memory. Let's get some fans blowing on them just to make sure they live a long and happy life. :D
Ok, couldn't finally resist while waiting on the DFI nF4 and put the VX in my DFI Infinity rig.
First of all, they didn't want to run 2x512Mb dual channel 1T 2-2-2 even 220fsb .
But that's probably because the memory controller on my Infinity just plain sucks (it did the same with 2x512 Mb Kingston BH-5).
So I just started playing with them separately, that is, in single channel configuration (1x512Mb).
The first results (I'm doing the burn-in simultaneously as well, so only results from one stick, the other will follow).
3.2v: 243 fsb 2-2-2-9-12-14 memtest stable for 100+ passes.
3.3v: 247 fsb 2-2-2-9-12-14 memtest stable for 100+ passes.
2-2-2-11-13-15 in memtest gave ~20 Mb/s less bandwidth so I just remained with the more aggressive timing values.
Heatspreaders are on, and a fan is blowing on the ram.
The board is unmodded, so the voltages are supplied by the mobo, my PCP&C (vanilla 510W) 3.3 rail is at 3.42 (with the built in pot maxed out).
We will see how it goes further.
Here's my max so far, with 3.6v. Will do the full 3.1v - 3.6v test tomorrow.
http://img.photobucket.com/albums/v6...fhan/260VX.jpg
wow no errors till 195 passes then none again up to 260. Weird.
It's probably just some small insect getting zapped by one of the PSU rails. I'd still call arj's overclock stable.
Ouch, that poor insect :p:Quote:

Just to add from personal experience, I wouldn't call memory memtest stable in the 5th test without at least 50 passes... Often you see first errors popping up around the 20-30th loop and then the number of errors building up slowly (the situation where usually the burn-in should come into play :toast: )
I haven't tried your advice yet, but my BH5 sticks are 2x256... certainly a 3000+ winnie doesn't help since I already tried that too :DQuote:

gotta burn this mofo :D
keep it up matey!
man the method that i am trying isnt working yet i dont know why but, the errors stay the same...
unfortunately not all memory benefits from burning in. Your's just may be stubborn. How many errors are you trying to rid of and at what speed and voltage?
MarilynMX,
could you test 3.1v-3.3v too please?
and is it fair to say your memory does this? I wasnt 100% sure from your post
3.4V 249 MHz
3.6V 258 MHz
3.7V 261 MHz
3.8V 264 MHz
3.9V 265 MHz
Ulti,
Could you post your results from 3.1v-3.6v please.... or as much of that range as you can? even if 3.1v only lets you do 190 MHz 2-2-2, results is all we want :toast:
mrlobber,
thanks dude, I'll put you down as 1x512mb for the following speeds...
3.2v: 243 fsb 2-2-2-9-12-14 memtest stable for 100+ passes.
3.3v: 247 fsb 2-2-2-9-12-14 memtest stable for 100+ passes.
Interestingly, I've never seen VX doing Trfc=14 on AMD64, but you seem fine with it :D
Garrett,
2x512 does put more strain on the memcontroller so maybe your CPU is on it's way out and it jus wont take it anymore :(
Either that or it's time to get that RMA in motion hehehehe
Tedy,
are these results with 1x512 or 2x512?
* 235 2-2-2-11 50 loops error free
* 238 2-2-2-11 10 errors after 2hours of memtest#5
Jupiler,
Biggy Cheers for the sticky bro! My first one at XS :D
Adding new results now, thanks everyone!
I wont be here for a few days so no updates till I get back... I expect results from everyone tho! :)
NP, Rabbi_NZ. ;)
Still testing 2*512MB on my DFI at 3.1V, as you requested.
220 and 225Mhz passed test #5 (25 runs).
So far, 230Mhz, 2-2-2-5,1T seems ok, no errors.
Will try some more tomorrow, getting late here.
Rabbi_NZ you are about right. every level represents the max expect 265MHz since I just stopped at 265MHz, I was kinda too chicken to jump on 266+ at that moment. Tonight I will try higher FSB with VDIMM NO HIGHER than 3.9V
some screenies taken from Sandra 2005 and everest home edition, please see for yourselves
I don't have any soft to show my VDIMM and I know some people don't believe my ram could survive and kick around. I recalled andyOCZ said any more than 3.4V would not help with FSB increase but only brings mass heat, seems it doesn't work on mine.
I also have some shots for ddr500 if you guys want to make a comparison I can post them too.
Add: Rabbi_NZ I used to test on 3.1~3.2V well I can guarantee 200MHz 2-2-2-5 1T stable or maybe 210ish; 3.3V let's say 240MHz max. Before I was running 240x11 since I got best Pi result(250x11 bootable but Pi unstable).
i use 1.5, works fine..... one of my UTTs died on me so can't contribute any info on that, but now have some VX :banana: loving it, hit 245mhz reading 3.26v under load, need to burn it in and will report backQuote:

cantankerous The date was Dec 18th or a day before. Actually I'm worried about my mobo way more than the RAM~~
bobmanfoo I put down the voltage shown on booster during test. please bear with my limited knowledge, why would you need the booster if you had your board vdimm moded? according to my situation my booster always keeps same VDIMM no matter idle or load. So both my RAM and booster are behaving really weird...
my vdimm mod only goes as high as my 3.3v, with my +3.3 rail at 3.34v i get 3.27vdimm, i don't really feel like running my +3.3 rail at 3.5v 24/7, i'll be running my VXs at 3.5v 24/7 when i fully break it in
your vdimm doesn't drop at all? is this according to the ddr booster led or from a multimeter? my ddr booster doesn't show the drop,only when i use my multimeter. my vdimm doesn't drop when priming or gaming only when memtesting
ok well mine doesnt seem to be responding to burnin:( i gues im gonna get another kit...
:::update:::i cant even get 2-2-2-6 @ 200mhz 3.0vdimm WTF :stick:

I've been out for whole day...now back on business.
265x10 superPi 32s, 266x10 superPi 31s ??
I had little time for tests so now I can only provide a hard fact that 3.9V gets me as far as 266MHz, same timings.
Guys I just realized my DC is even worse than my cam phone, look at these pictures!
I ran memtest at 265 again thought I should obey Rabbi_NZ's 25 passes rule as everybody else
Holy crap im jealous. 266 and 33ns latency?
]=(
where in ontario are you and where did you get your sticks? Have you ever thouched them at 3.9v?
I've tested another cpu, a 3000+ and it doesn't help $h** you know...Quote:

I'll definitely get some G.Skill... that way I'm 100% sure about getting 275 DC @ decent timings... it's time for some MHz power ;)
With 3.1V, 231Mhz is the max I can run 2*512 sticks Memtest errorfree.
Strange thing though is that, at 221Mhz and same settings, I get a registry error when XP boots, and a memory error after some time.
After giving it 3.2V, all seems ok now. Weird.
seems this twinmos is really weird,eh ?
thats not so strange, my VX doesn't do too well until 3.2v, then it takes off, i've only gotten to 255mhz so far with 3.3v, with 3.1v i can't get 230mhz stableQuote:

cantankerous I bought my ram from Poklik
as an authorized OCZ retailer in Montreal. I was told by a XS member that they got only 1 set left so I took it home. Yes I'v been feeding 3.9V to my ram since two days ago. I'm going to get some TCCD to replace these VX during summer.
3.9 is a rediculous voltage to be running 24/7 those will die fast.
does anyone else notice how many of these kits are bad?
i mean i love OCz and all but, WTH ive only had my hands on 2 and both of mine are bad..
ive also heard about alot of dead sticks and rma's..
Yeah, IF those sticks live until summer... 3.9v is foolishQuote:

MarilynMX,
Nice sticks dude.... Take good care of them! :D
If you insist on using 3.9v it will be interesting to see how long they last... with your COLD temps it will def help the cause but I would still be very worried at 3.9v.
Updated your results.
bobmanfoo,
You look to have some of the better modules around... congrats :D
Did you read those voltages from the booster itself or from a software monitoring program?
Apparently if your 5v line on PSU is not at 5v it will cause the Booster to read incorrectly... is yours at 5v?
aCidbAbY,
sorry to hear that bro... those sticks looked like were going to be real nice too.
Hopefully OCZ will get you some nice handpicked modules for all the trouble you've been through! Good luck
TEDY,
Updated your results... cheers :toast:
DUAL TWINMOS
3.3vdimm
245 2-2-2-11 #5 32 errors in 7 hours....wtf is liming me ? I need more vdimm ?
3.2v 245mhz 2x512
3.3v 252mhz 2x512
3.4v 255mhz 2x512
might do higher i dunno, crashes after 255.
memtest stable, 30 passes on #5, 2-2-2-10 upto 255
odb so raising vdimm doesnt help a lot afterall ....just few mhz ...and on AMD64 system :(
can you try 3.6 ?
i never tried 3.5v+ yet, but will tonight. im still happy with 255 tho, when i first burned in when i got them the end of november, highest i could get was 242 at 3.4v
my +5v rail is at 5.08v, but i don't use the ddr booster's leds anyway, not really accurate, i measured the voltages with a multimeter, ill be testing higher voltages later...making the fun last longer ;) i've hit 265mhz stable with a minute turn on the ddr booster from 3.4v....Quote:
