[WR DDR2] Cas 4@720,4 and Cas3@552,1 : Crucial Ballistix PC8500 et DFI P965-S

[Florent]

After having had the WR Cas 5 (now at Jmax) then WR Cas 3 (that I still have), I succeeded thanks to my second Ballistix (for the two others, it was the first Crucial) and my DFI P965-S to reaching a nice 720,4Mhz Cas 4, the new WR Cas 4, the old one was held by Jmax (still him) with 717,1Mhz

DFI P965-S (0613) : Vnb @ 1,75V ; Vsb = 1,6V : Vtt = 1,425
Crucial Ballistix PC8500 @ 4-5-5-15 @ 3,375V
Cooling : Lots of Fans

Very nice!!

did you try higher voltage? or was that as high as you dared?

THat rig is just an insane mess! :)

[Florent]

Thanks

This is the highter voltage that i can to put but above 3,3V the profit is weak

[Darkstormz]

Impressive!

[bassie]

Nice, but could you prove it is real and not done with memset? Spi runs etc.

And do you have some screens of your sub-timings?

[Ming@s]

Very nice!!

I didn't use memset.
Which prove, wants you ?

wow congrats mate... but 3.375+ vdimm :eek: nice and toasty PCBs and ICs there :D

Yes, that's some motivation. Well done.:D

Some spi runs on same MHz but different timings (not subtiming), picture of your dmm showing your voltage.

Not that I don't trust you, but something like this could easly be faked.

[coop]

^^ I don't think that is really called for.

[Achill3uS]

this Crucial 8500 modules are crazy :D
amazing result :up:

[Florent]

Thanks all :)

Yes, I know but I didn't use Memset purposely for that

For showing my voltage with a multimeter, I must find measurement point on DFI
But I've my examination thus I would do that Wednesday ;)

I will also add that a memory which can hold 720Mhz Cas 4, can too reach 552Mhz Cas 3 :)

[boblemagnifique]

Impressive Crucru , Nice Job Florent ;)

[erwinz]

congratz.. :)

very nice DFI Infinity 965P-S and very nice crucial mems.. :)

:woot:

[luihed]

Thats awesome dude.... Most I did was 530 but failed spi.. that was at 3.23v, @ 3.375v it killed my stick:( ... Do you mind posting your dram timings setting for the 720fsb run, not the numbers but GTL, DQ modes etc... thanks

Doesnt really matter in this game, he can have subs at 100-100-100-100 its still a WR and still great achievement:stick:

[erwinz]

mm.. so the 0631 bios makes the difference??

[forevera]

rusults is "WOw" but the video is :rofl: :D

[Gautam]

Wow, very nice. I kept throwing voltage at my 8500's but I stopped around 3.1, because nothing past 2.8 or so even helped them. :( And no matter what they wouldn't even do a 1M at 500 CL3.

I POSTed in BIOS at 700 CL4 a couple of days ago...hrm...maybe I should give that another run.

[v_parrello]

Very impressive! :eek:

Are the RAM still working well? :D

[Eldonko]

3.375v! whoo hoo!

[Fr3ak]

Crazy voltage for DDR2 sticks :)
720MHz Cas4 is very impressive! :D
I just wonder that you got the Cas3 and Cas5 WR with one stick and Cas4 with the other stick. I would have expected a stick that is that good at Cas3 and 5 would be better at Cas4 than a stick that was worse at Cas3 and 5.

[Romano]

that's woooow.....

[Zannema]

Wow, impressive score :up:

Run Single stick and up the voltage on the northbridge to the max. 500mhz cas 3 dual channel puts a good deal of stress on the mch. Chances are that's why they aren't scaling over 2.8V.
