WR CAS4 and CAS5 on Geil PC8500 - OCM - First memory reaching 700MHz

Hello,

P5B Dlx Wifi BIOS 0614 VDDr modded
E6600 Step 6b2
2x512 Geil PC8500 C5 Dual Spec cooled by 80mm fan 2.8V
Memory not pretested, fairly bought, not lended by brand manufacturer.
Very old XP Pro SP1 no tweak

WR CAS 4 SINGLE CHANNEL 687MHz = DDR2-1374

Validation


WR CAS 5 SINGLE CHANNEL 710MHz = DDR2-1420

Validation


Other results (dual channel, cas3, 4-4-3- and validation) on OCM. I have a huge chipset issue since my dual chanel results are very close between 4-4-3-12 and 5-6-6-18...
Keep tuned :)

:slobber:
any bandwidth pics @ that speed ?

congrats
great clocks waiting for benching
________
buy silver surfer vaporizer

For bandwidth, I need a better cpu.

wow... 710MHz :slobber:
:clap:

Nice, thats xtreme :)

damn that's fast...:eek:

Geil is alive :toast:

Max screen avec VCore NB @ 1.65V : 706MHz
Max screen avec VCore NB @ 1.45V : 656MHz
Max screen avec VCore NB @ 1.25V : 600MHz (boote 6x285 dans ce cas)

So I was chipset limited :D

Does the other stick you have also that well like this stick in single channel ?

:eek: 700 mhz is incredible!

2-3MHz "worse"
But I'm chipset limited :D

wow nice

So chipset voltage is very important even with ram at 1:2?

Yes, and probably also important in 2:3 ratio...
I'm doing more tests :fact:

wow congrats

ram faster = chipset faster/more work
so more voltage is needed

Insane clocks!
Did you test them with less voltage too?

so if its the chipset you think ...
... so WC and high Volt the chipset you should ...

Yeah 700+ is truly insane, but nothin better than improving your own WR :D

Congratz man, honestly .. :toast: :toast:

Yes
Max screen 5-6-6-18 620MHz 1.8V
Max screen 5-6-6-18 660MHz 2.0V
Max screen 5-6-6-18 704MHz 2.45V

Cas 4 need far more Voltage to reach Cas 5 results
Max screen 4-5-5-15 586MHz 2.15V

amazing... only 18 months ago HALF this speed was unthinkable.

Great results.:toast:

omg...your results are so...:woot:

you could be an xtreme ram tester ...:D

great jmax :toast:

No improvment since Vmch mod...
1.65V Bios = 1.56V REel.
I tried 1.65V, 1.72V and 1.8V and max 2-4MHz better than my previous scores.
I don't understand why :(
