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

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 six layer PCB (BrainPower) and is more resistant from voltage damage

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 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 (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

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
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

wow very nice much better than my old OCZ PC2-8000 VX2 which did max around 585mhz 4-4-4-x at 2.5+ v

2.97v vdimm You have a set of balls

scotty1991

Thats a lot of voltage! O_O, how did you cool the ram?

pcuser

Nice ram

I tried 2.55 on my crucial PC2 8000 to get 670mhz and i though that was to high

No mercy for your ram

The boarder ~ 2.9 - 3.0 isn't nothing special for good brand D9, especially Mushkin and G.skill (I have tested many sets of XP2 line and HZ with that voltage and every set, would be around 30+ lives today without any trouble ). But of course somewhere is the limit... yes I would opose against giving more than 3v on my private set of ram (this set of HZ is my private ). Absolute MAX of voltage for HZ which I would give is ~3.05 and no more. I don't like killing RAM

OCZ I cool with normal Zalman 120MM fan at 12v, G.skill with more voltage is cooled by Delta 120mm @ 12v, yes, some tough air cooling

And some more result from OCZ

350 FSB (1:2) 700 MEM 5-5-5-15 2.55v real booted from bios and done some SPI1M action

Been a while since I've seen posts from ya.. nearly forgot how much vdimm you shove in your D9s

I don't now why images don't want to work... buuu






BTW

I did a mistake, OCZ don't use BP PCB, probably HJ-MI 8-layer stuff

weird images in 1st post worked
