OCZ VX, Best Memory made since BH5!!

[enzoR]

what does PCS die mean?

[rapra]

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.

[enzoR]

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?

[enzoR]

well that shouldnt matter, if the chips are capable of 240 2-2-2 on amd the chips should be capable of that in any platform aslong as they dont have compatibility probs. like the 875p only likes them with cas 2.5 or something. thats a chipset thing.

[Rabbi_NZ]

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

[ojdr2001]

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???

[Rabbi_NZ]

tried another CPU?

[cuddles]

Guaranteed 240 @ 2-2-2. I love you OCZ

[ojdr2001]

Why another cpu? My mushkin Level2 (BH5) 2x256 do 280 1,5-2-2-5 with same cpu....

problem cannot be cpu or system.....

[Rabbi_NZ]

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....

[enzoR]

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

hehehehe 2 voices are better than one

[ojdr2001]

Ya quite a difference of course. I know I cannot expect 270 or above from this ram but at least 250/260 yes..

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....

[enzoR]

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?

[cuddles]

Run benches at 2 and 1.5 and find out yourself.

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.

I tested with CAS1.5 on my VX modules and it made no difference. Everyone has a different set-up, even when the components are exactly the same. Test with 1.5 and 2.0 to discover what setting is best for your system.

[Tony]

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.

[cantankerous]

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.

[Playful_Buffalo]

oj, people usually benefited from burn in


LOL @ letter

[SteveOCZ]

LOL @ letter

Agreeeeeeeed

[RocKer]

If you suspect your harddisk, try running memtest86+ from a floppy.

All run test5 of oczmemtest at 2-2-2-10.

Q: what is the best performance setting,is it 10x224,9x230 or 8x231,its now running at 10x224 at 3.40vdimm and prime stable.

[Rabbi_NZ]

Rocker, what is your VCore?
10x224 will smoke your other scores!
