New OCZ Alpha Titanium VX combined with DFI Blood Iron

[Xtreme Addict]

Yesterday I simply couldn't fall asleep so I decided to overclock some memory. As I was really suprised that DFI published at last new beta BIOS (12.05) which sharped compability with Micron D9 stuff :thumbup:

Firstly, I have started overclocking with a new beautiful, glossing OCZ Alpha Titanium VX PC8000 4-4-4-15 by default

New revision uses black eight layer PCB (not BrainPower) and is more resistant from voltage damage :drool:

Although, new D9 GMH are created only for CL5, especially OCZ stuff, this set clocks quiet well with CL4

So let's start this play with CL4




560 MHz 4-4-4-12 @ 2.35v



575 MHz 4-4-4-12 @ 2.47v



600 MHz 4-4-4-12 @ 2.65v

These OCZ sticks are surely the best set of OCZ memory which I've ever had.

Orthos

My favourite memory "burning" application :thumbup: Stress Prime 2004 "Orthos" (priority set to "9").



616 MHz 5-5-5-15 @ 2.14v I think, it's quiete cute



640 MHz 5-5-5-15 @ 2.27v I like this score. I goaled to achieve "650" MHz stable but... ehh everywhere are obstacles This is (640 MHz for memory) absolute MAX stable for my Blood Iron.

To be continued... CL5 again



675 MHz 5-5-5-15 @ 2.62v (so high voltage don't needed indeed)



One step further... 680 MHz 5-5-5-5-15 @ 2.62v



I was convinced that it's absolute MAX - 685 5-5-5-15



691 5-5-5-15 @ 2.69v stress

This result is really nice. I like it entirely My brave-hearted Blood Iron achieved it's max once more :drool: (It shall also do it with ~ 2.6 -2.64v max)



Max screen and that's all for dual channel with this mobo. Now I am waiting for selected board - LP P35 UT, which is much better than budget Blood Iron But, summing up, new bios for Blood Iron have done some good work - better compability, better OC and less troubles than ago :nod:

The end...

(really?)

And the last result for today - with G.skill HZ PC6400 2x1 GB (new week, green pcb ). With old bios on DFI they were capable of doing only ~ 565 MHz, regardless for latences



630 MHz 4-4-4-5 + strict alphas.

1) I am waiting for better board and I am going to achieve MORE... and I am also waiting for OCZ Reapers PC9200 2x1 GB :nod:
2) For HZ's, this result isn't max because with CL5 it overclocks also to only 630 MHz
3) DFI is great motherboard, but especially hard to stabilize
4) I think it's quiet good set of OCZ D9 stuff :thumbup:

black pcb is not brainpower as far I remember, we use 8 layer for all our micron based dimms as this allows it to clock higher. Also its not more resistant to voltage...to much kills the IC's and this is the same for any PCB.

Nice clocks though...please look after your memory

nice results but the VX don't like CL5 so much, the new black (ocz marked) pcb's are rocks, here is my Reaper PC2-9200 oc report on Asus Blitz: 1500MHz DC

push, push

Thanks for reply!

Yes, this set is very good and I have to look after it
refering to PCB, I didn't know and that's nice that OCZ uses 8 layer PCB. From my expierience some D9 memory (for instance Mushkin or G.skill) are very resistant. And others very fragile... e.g. Crucial and in my opinion it depands of PCB... maybe not only pcb but elements on it

But I am not a RAM constructor

Yeah, new OCZ rocks all the line. I had really good PC8000 Platinum also At this moment my Blood Iron has a wall, not memory I need a better motherboard...

And I am waiting for Repears 9200

the black pcb was commisioned for the German market as German end users prefer black components...hence we had an 8 layer black pcb released for them.

Regards components helping the IC's with voltage, you seem to read a lot of forum talk We know why causes Micron to die and its nothing to do with the components or 6 layer Vs 8 layer etc...all I will tell you is keep the voltages as low as you can to help lengthen the life of your memory and respect the warranty max voltage.

Tony, i think he didn't meant that.
8 layer PCB can help to handle higher voltage throughput through PCB. I have seen some burned JEDEC PCB with BH5 using more than 3.3Vdimm because PCB simply can't handle that. Actual Micron IC sudden death, electronic migration or degrading has nothing to do with PCB layers. But i guess you know better about all this.
Its quite funny that OCZ use black PCB only because Germany enthusiasts prefer that. Maybe its MSC Cellshock syndrome

[Tony]

Only the signalling layers are split better on 8 layer over 6 layer, hence lower crosstalk (as far as i remember)

I just did not want anyone thinking the 8 layer black was different then the 8 layer green as its the same thing with a colour change ...forum talk and twisted stories sometimes do get out of hand.

Yes, I now about "electron migration" itp. But I tell own experience: I had one set of Mushkin XP2 PC8500 to kill because it didn't do even 600 MHz 5-5-5-15 2.4v (my friend has sent it to me as he couldn't kill them... they were/are too tough. I was playing with them for among a month with voltage ~ 3v (but with a fan on it because I didn't want to burn pcb/dimm or something else). And nothing helped. I can't kill this set till now and is perfectly working, without even any trouble with booting with 1.8v And many of my friends have dead Crucials at stock frequency and stock volts

Somewhere have to be a reason...
