OCing the CPU-NB (Not NB chipset or it's voltage):

Pay most attention to the CPU-NB Voltage (once again, NOT the VDD voltage). Dram Voltage is also an "AUXILARY Votlage for the CPU-NB (IMC- Intergrated memeory controller... If you didn't already know that!) So running more than 2 Dimm Slots populated at once may benefit from a light increase in Dram Voltage as well as CPU-NB Voltage.

NOTES:
-Hypertranport Sync Flood Errors are "Mostly" caused by Lack of volts to the CPU/ CPU-NB.
-Freezing is normally caused by lack of Dram Voltage
-Errors or bluescreens can be caused by Lack of voltages.

TIPS:
- Best to Download Prime95 and FIRST run Small fft's test on CPU to ensure that CPU OC is stable THEN "IF" stabel run Blend mode to enusre whther or not CPU-NB (IMC) and ram are stable.
- It's Best to Run Blend For 12-24hours to ensure complete Stablility!
Thanks for that

Any rough voltage figures for say 250-260 FSB and a 2600Mhz NB clock?

It probably varies depending on the adhesive.

I found this reference in a manual regarding mounting an accelerometer, if it gives you any indication:

"Hot glue mounting is appropriate for temperatures
below +93°C to -18°C. Above +93°C, hot glue loses its
stiffness and frequency response is adversely affected."

You might want to look into a polyurethane based adhesive, rather than hot glue.

Hm. Why would cleanup on the GPUs be an issue? If you covered the mobo only in oil (not submerge the whole setup), you could probably keep the oil below the top of your PCI-e slots and therefore only have to maybe have to clean the PCI-e socket interfaces. Maybe?

I don't know what kinda setup you're trying to make. I just was throwing out ideas. Like I said, I'd love to experiment with extreme OCing but I don't have the time being single and have to take care of everything in life by myself.

Even weekends are tied up with helping family, helping neighbors, running errands I can't do after 6pm when I get home from work, etc.

Maybe if I ever get into a good job where I have time up in NC, I could join ya doing some experiments. Would love to help, and might have spare parts to donate into them.

Anyways...let me know. Love to know what you decide/do.

That's a good question but it really depends on each setup.

Just start by lowering the multi's on everything.
The increase the HT Ref Clk by 5Mhz at a time rebooting between each increase. once you can't post, back down the HTR Clk until you can post and get into the OS and teset P95 Small fft's stable for 6+ hours. You may have to reset the CMOS to figure all of this out. This will tell you the "Max HTRClk @ Auto Voltage". Once you know your max HTRClk at Auto Voltages, you can either choose to work off of that or take it a step further and raise the CPU Voltage and find the "Motherboards Max HTRClk @ Any Voltage" . Or leave the Voltage as auto, the HTRClk at it's Stable Max @ Auto Voltage (testing with P95 Smallfft's first of course) and find your Max CPU Multi with that Max HTRClk @ Auto Voltages.

There are numerous Goals when it comes to OCing a system. You just have to figure out what you want (within reason and capabilities) and aim for that!

The PhenomII 9X5 OC thread is a good one to read through as well!

Sorry about this, i am sure I am repeating here, as i found my question, but not the answer.

I will soon be going back to the liquid cooling setup I used on my last rig(MSI...something something dual opteron board).
I only cooled the 2 CPUs on that one, and want to include the NB/SB chips this time, as this board has some issues in that dept(NB really).

Is there a known good block to be sued for the NB/SB chips?

Will I need to add anything to replace the part of the cooler that covers the power regulation chips?

Thanks for any help on this.
I'll keep scouring the webs and post back if i find something.

Found this in a different thread, looks good, waiting for results from poster.

Koolance has some products that will work for this board. I was considering them until I replaced the NB/SB/ MOSFET HS TIM and it lowered my Temps substantially.

Well, I got my 555BE up to 3.96GHz so far. 1.385V. Seems like I go any higher, it fails even if I go up to 1.425V.

I will work on it more this weekend if I have time. I am bound and determined to make 4GHz on air.

Cool NC. I hope you can make that sucker hum and get the LN2 and stuff kickin it.

I got 3.96 on air so far. Man, if I was just a decent OCer. I guess I need to study more and get it down-pat in my head so I can do it better.

I get some personal stuff taken care of, I will do that.

Good luck man

I just got mine up to 4026...... so now I'm to the point of fine tuning.
THIS THING IS SCARY FAST... for $100.

I have only upped the volts for CPU/VDD and the CPU/NB.The rest is on auto.

Any suggestions would be greatly appreciated.

This board has more settings that I've ever seen. I'm sure I would not have bought it, if it weren't for this thread, and all of the knowledgeable people on it.

One more thing.... is the Aux temp in Everest my NB...?
