DFI ULTRAII-M2 + x2 3600+ Brisbane

[nzbleach]

Ok so here it goes. Basically I had to update the bios of the motherboard to get the cpu to boot at all. Im having the same problems as I did with my old 3800+ x2 cpu. The 667 ram divider does not work so Im having to use the 533 divider and dropping the multi to 9x (default 9.5x) and raising the FSB to get higher ram speed. Now I know this ram does 500mhz on my old CPU when I was running 1:1. Im getting all sorts of funny problems taking this ram above DDR800 using the 533 divider. This is the OC I have managed to get stable so far :

As you can see coretemp is bugging out and not showing the correct temps :

I really want 3G and I hear people with biostar T-force 550 boards talking about MAL ? This is all the options in my bios and if theres anything in there that might be able to improve my OC please let me know. Bare in mind that I've tried 5-5-5 timings for the ram and I've hit a hard wall of 2.85- 2.9ghz. Even the voltage @ 1.55 volts is not getting me past the windows loading BSOD's. I get long beeps when I try 667 divider and when using 533 anything above 2.9ghz is BSOD'ing at the XP loading splash screen.

that didnt change anything. weird , 3ghz @ 1.475 volts boots and gets to the windows splash screen but does the neverending XP loading bars. 3G @ 1.5vcore = BSOD. 3G @ 1.450 vcore = no XP load screen, just reboot.

[funnyperson1]

Try using the 533 divider with 9.5 multi to see if you can get further, I believe the half multi chips don't like being run at even multis and vice versa.

[nzbleach]

hey mate, looks like your getting similar results. What vcore does it take for you to get to 3g?

[MrW]

:idea:Just a guess, try lowering HT link. 1.56ghz might be to high.

Quite wierd no-one noticed that yet :P good find! But increasing the Vcore helped didn't it... from no boot, to endless boot to BSOD. Maybe a bit more and it will simply run?? And a good idea is goin to a half multiplier, which has been made for this cpu... might help some...

I think there is something funny with AMD CPUs and NForce chipsets with high HTT. With my Asus Crosshair (NForce590) I have used two CPUs, X2 3800+ and Sempron 2800+, and all of them lose multipliers with high HTT, even when the HTT multiplier is drastically lowered. It has something to do with the more obscure RAM timings but I can't figure it out. For example with the Sempron 2800+, if I get it to 300 HTT (300x8) then the DDR2-400, DDR2-533, and DDR2-667 dividers don't work, only the DDR2-800 divider works. Which doesn't make any sense, since both the 667 and 800 dividers are /5! Nothing helps, higher voltage to northbridge, adjusting all kinds of RAM settings, more Vcore, etc.

Hi!

Very interesting, I have the same board with a x2 4000+ brisbane. I get 2,8GHz with 1,45V vcore stable, but in the region between 2,85 and 2,9Ghz I hit the wall too. 1,55v vcore doesn't change anything...

greetings

I've found it fairly progressive between dividers. However I did find an interesting thing with the DFI 590 board, in that there was a HTT range that wouldn't work on one of the dividers. IIRC it was between about 270 and 300.. found by accident.

The weird thing with my NF590 Asus Crosshair is it starts to lose dividers as the HTT is raised. With the Sempron 2800+, up to around 260 HTT all the divders work. Around 270, then the DDR2-400 /8 divider stops working. Around 280, then the DDR2-533 /6 and DDR2-667 /5 go as well. 300+, only the DDR2-800 /5 divider works. Which doesn't make sense since it's the same /5 as DDR2-667. Mind you this is with 2x1GB of RAM, so I was convinced it had something to do with the IMC, but I was told it was something to do with the chipset. With 2x256MB of RAM, all the dividers work and I can get to 370 no problem before my RAM gives out. I experienced something similar when using an X2 3800+ and 2x1GB, as the HTT was raised the dividers would stop working unless I adjusted the clock skew. However with the Sempron NOTHING works.
