The AMD Phenom II OC'ers Club

Yeah, I had to mod mine slightly for use on the tech station.



Yup, that's the Sunbeam. I sold the Dimastech bench even before I had it together. Way too bulky for my liking. The Sunbeam is simple and functional.

nice rig Paul

Trying it in my crappy enclosed case on air look at my northbridge and I'm thinking it will prime, but I just started to test it.

As promised...please accept my apologies for the poor cable management. Between work, kids and my Masters thesis defense, I've been a bit busy.

You need to be running both those sticks in the red slots.

Pg. 2-15 in the manual.

Yeah, 890FX changes back to the old way of doing things(thank god), as then the DIMMs aren't so close in dualchannel.

Can't believe I missed that! They are already clocking well. Maybe I'll get 'em over 2000 yet.

 

[cadaveca]

Can you get 3600NB @ 900mhz mem? 13k+ read everest is so close...just lovely numbers.

 

[dumo]

Bios 0801 test

Boot up and run

Cooling limit @ 3.4ish Ghz. NB.

More then have to run LN2

Just loaded the new bios and switched the ram around. I'm going to mess with NB and HTT now. Should HTT and NB frequency be clocked equally? The HTT only goes to 2800. What about HTT voltage, and reason to increase that beyond stock? I feel like such a noob, all over again.

Quick Everest:

 

[cadaveca]

Look at yours, Paulie, and then dumos...lower cas doesn't alone account for the overall boost...that NB speed helps so much.

You'd get 11.3K/11.4K @ 800mhz CAS6 2800NB.

I'd not bother raising HTT volts, if you gotta do it, put HTT lower. And be careful going too high on NB volts...trying to keep NB 60% of vDIMM will help make the OC last.


So, with ACC on SB, and IOMMU on NB, it becomes more important to keep both at the same speed to help stabilize everything. So you want to look at everything as a big package, memory speed, NB speed, HTT speed...I think for most users, 3200NB/HTT(320 base clock), and 1600mhz memory(CAS6), is THE specific sweet spot to hit.

But I dunno how ASUS's hardware ACC bypass fits into this. I need a board.

Needs some manufacturers to get it going too. BEMP profiles would be really nice. We'll see what happens with the bioses....I know they are still a few revision off yet.

OK, so what is max safe voltage on the NB and CPU-NB? What about running memory ganged vs. unganged?

 

[cadaveca]

NB is the same process, but I dunno about how the IOMMU works, and because it's a direct link to IMC, it's got to be considered. So I have no specific answer unless someone give me more info, or I start poking around the hardware with a meter. And I don't have the hardware.

CPU-NB max, same as cpu volts, as always. Again, you want to keep it @ about 60% of vDIMM, too...

Ganged for two sticks, Unganged for 4, for the best scaling.

Now tell me, with the ram in both near slots, did it say dualchannel @ bios boot?

I didn't bother to check whether it was dual channel or not when they were both in near slots. I'd guess the answer is no. Here's another Everest/LinX run after tweaking the memory a bit more.

 

[cadaveca]

Those temps just seem so odd...and I wonder what true load voltage is...have you checked the ProbeIT with a meter?

Pretty fast though, hey? And easy too...

Yeah, the temps are very low. Not sure if it's a sensor issue or these chips just run very cool. I tried to use my infrared thermometer too, but it's really hard to get a reading around the block. I can tell you that the block and my rad are very cool. I can't find my multimeter to test true load voltages. I will say that even with loadline calibration enabled the load voltages in cpu-z are quite jumpy.

Edit: I just failed a LinX run after I dropped my NB voltage from 1.3v to 1.275v in the 15th cycle.

Edit...again: It seems that I NEED CPU-NB and NB voltage to be at 1.3v to run over 3000 NB/HTT. Any lower, and I fail LinX between the 15-20th cycles.

1.3 should be perfectly fine. AFAIK, 1.4v is fine too. But as you get closer to vDIMM, you're gonna lose stability. When volts get too high...you'll know it...the CPU will bite back at ya.

Just passed a LinX 25 cycle run at 4.21ghz/3130 NB/HTT/DDR3 1926 8-8-8-20 1T. Screenies tomorrow. I'm too damn tired to do it now, and I'm going to bed.

nice wow!!!!

 

[claylomax]

Hi there; back home I have a system with a phenom II 550 and when I up the multiplier on stock volts it won't downclock when idle . Is that normal?

What I mean is that it stays at 3.3ghz all the time; is there any way around this?

 

[brandonwh64]

turn on cool and quiet and it will down clock its self once its idle

That's pretty impressive and it's six cores!

Yes it sure is! i wished someone that had a DDR2 capatible board would test the 1090T on it for it OC abilities

 

[trt740]

which clock do you like better for 24/7 use

 

[cadaveca]

250mhz base, of course. Benches will be very similar, but I really think I can feel a difference in dialy tasks @ 250mhz. Maybe just a mental thing, but I seem to be able to notice a difference.

 

[erocker]

Everyday stable for me in my signature. Still wish I could transplant a different memory controller in this CPU as I could then use less voltage/less heat/ higher OC, but this is just gravy! I almost don't want to use any other bios, due to my stability.

Here are some bios shots.
