OCZ VX, Best Memory made since BH5!!

[andyOCZ]

I'm a bit carefull before buying these modules
2*256Mb pc4000 OCZ VX ...
After reading this thread, I dont realy know what to do ?

Everybody advices to run these modules at an DFI board but I'm using the MSI Neo2 Platinum...

Any info ?

If you can't put 3.3v-3.4v into the VX memory, it will not work for you. TCCD is best at lower volts.

I have a OCZ DDR Booster
And I already have some tccd (OCZ pc4000 gold rev2) who manages to do 290HTT but i want tighter timings.

Any advice ?

I think that UTT at 260~270mhz with tight timings get way better perfomance than 290mhz loose timings. (u could use a divider and done )

1) UTT @ 270 is damn rear... and probably not possible at 3.5vDimm unless you get damn lucky sticks.

2) I am pretty sure OCZ pc4000 gold rev2 are Hynix DT-D5 chips... Hynix for sure but the code may be different

Im not saying 3.5v, thats way to less. All the DFI Owners got 4volts to burn those chips up to the sky .

What is the safe 24/7 v for the vx ?

What is the safe 24/7 v for the vx ?

if you have a fan blowing over them id say up to 3.7V is safe enough for 24/7 use but the best way to decide is by how they clock.

e.g. if you get 265MHz 2-2-2 at 3.5V but only up to 268MHz at 3.7V then better off running at 3.5V.

however if say they wont go above 250MHz at 3.5V but will go to 265MHz at 3.7V then you now which one to go with.

i disagree having had 2 sets of VX and one of twinmos UTT all doing above 265MHz at 3.5V.

I'v got a xp120 and it stretches over both mems so the cooling problem i think is solved.

[Revv23]

id be careful with 24/7 at 3.7, the max most went on BH chips were 3.6 24/7... but i guess i havent heard of too much dieing anyways...i think anything over 3.4 becomes a risk, but all overclocking is a risk, just a matter if you want to take it.

[Jacke2k]

Thats true but i think the vx has garanti up to 3.5 v

[Viss]

They are actually rated 3,5v + 5% makes 3,675v

[Der_KHAN]

so, i can rma my vx if it gets errors on 3.5v while 3.3v at the same clocks is stable!?

[Viss]

I just meant 3,675 is max volt you can feed it without loosing yr warranty.

[FireDragon]

PFFT warrenty...who needs it!!!

Any way this is some GREAT ram..you can get a little more performance out of by using cas 1.5 and not loose any OC...But i love mine better than BH-5 but hell it is CH-5-UTT...some new BH-5-UTT is cooming out here in the near future though...

wow, forgot they raised it.

[Gray Mole]

Just thought I'd post a taste of my VX results...

I'm running it at about 3.675


I'm impressed, only a little over a week of running it so far, and have gotten some pretty good results, though only 2meg SPI stable so far...

i take it you arent memtest stable then?

[Aleman]

@Gray Mole: Wow, 1.5-2-2-5-7-15 1T at 267mhz using "only" 3.675v Respect .

[Gray Mole]

Don't know mate, I haven't used memtest since I got rid of my DFI board, it was all right when I had memtest built in, but too much trouble for now...

'sides...if you're not 32m SPi stable, you're not fully memtest stable, I would imagine...

and some stuff in the piccy...I think I like the ram at cas2 anyway for now, at least until I start heavily benching it again, waiting for some vmods on my card so maybe next week...


Still not quite 4 meg stable yet, but it'll burn in I'm sure, and if it doesn't...well I have 2 other 24/7 rigs, and they run tccd...I want more speed, not more stability, but that's just me...


Gray

edit, that was meant to have the spd for the VX in there not 2 of the same cpuz shots

I've added a sub-37 pifast in there as well, it ran 269 at 1.5-2-2-5 long enough to take that, but I didn't want to risk losing it to a blue screen

[andyOCZ]

so, i can rma my vx if it gets errors on 3.5v while 3.3v at the same clocks is stable!?

No, use what works for you. The higher voltage if for modules that like that much. The voltage you need depends on your board and CPU.

[Gray Mole]

I'm not really sure I'd understand why you'd WANT to rma sticks that will work well with lower volts...

Generally I've found that you add voltage to compensate for instability, not just for the sake of it...

If you find that 3.3v works, and then you up your speed or tighten your timings and THEN if you have instability you add a little voltage, you might find that 3.5v works for you...

My FX-55 is unstable at 1.85vcore...but rock stable at 1.73vcore, both at 3.2ghz...I'm not gonna complain about that lol but if I can get some better cooling that'll let me up the clocks a bit more, I may need that extra voltage to stabilize it, and may find that it ISN'T unstable at those higher volts when the speed is actually using it...

You see what I'm saying?

[Der_KHAN]

yep, i know what u mean.

but because my mem is fine at 260/3.3 i was really hoping that it would do 270 at 3.5-3.6v so i could run it 1:1

and i thought since ocz gives a lifetime warranty for 3.5v they expect all of their VX sticks to like that much volts

hey have you tried the new 510-2 bios for ultra-d mate?
my max vx overclock went from 264 to 268 so you might get those few MHz you need.

Nice!

If they'll do that at 3.3, you might just get that with the extra volts...

How long have you been using them? After a while of burning in, they should stabilize at higher speeds I would think...

I had just found a setting for 270mhz that was working before I had some issues, so your will probably do that speed for you with a little playing, and possibly with some bios changes...

Mine is on NF3 Neo2, and your volts from the DFI(if that's what you're using?) might be more predictable that my booster...
