Guys will turning on and playing with ACC give me higher overclock or more stability?

and QuadFire is 8x, 8x, 8x, 8x = 32

This is my understanding.

Sooo, Marc!? You are up for nomination to be the operator of the MSI 790FX-GD70 Owners Club Thread here at OCN!? What are you're thoughts on this?

That's the general idea. Typically one must find the max stable clock for each core and apply a positive (+) % of ACC to the cores that fall behind the others...

Example:

All cores but core 2 are stable @ 3.950Ghz and core 2 fails in Prime after 5 minutes... Apply +2% ACC on that individual core and it shuold stablize it. It may need more though.

Hope that this helps!

What volatges do what and what do I need to concentrate on?

Asking this as I'm redoing my overclock

What do they all do and what's best to adjust to gain stability?

CPU VDD?
CPU-NB VDD?
CPU V?
CPU-NB V?
CPU PLL?
CPU DDR-PHY V?
HT V?
SB V?

Any advice would be awesome

um...

i don't know if it's conductive or not...so...

Have you thought about using some clear sealer like outdoor silicone? put a cover over the chips you'll cool with the solution you're gonna do, apply a layer, then cut the covers off, mount your CPU and cooling pots/fans/tubs and go for it?

Just curious.

I'm plastidipping the whole thing as we speak. Trying to coat it thick enough to peel off. I hate leaving evidence of ln2 usage on my boards.

What do they all do and what's best to adjust to gain stability?

CPU VDD?- Fine Tuning CPU Voltage (i.e. offsetting the Main V by .0025v)
CPU-NB VDD?- Same as above but for the CPU-NB Voltage
CPU V?- Main Voltage (Should be most concerned with)
CPU-NB V?- Main Voltage (Should be most concerned with)
CPU PLL? (Phase Locked Loop) Adds Stability to CPU freq. through the use of Alternate Freq "locked to the Phase" of the CPU Main Freq. (mostly if CPU Freq is jumping around causing instability)
CPU DDR-PHY V? Aids in stability of Higher Dram Frequencies (most evidience is pointing at the Stability of Dram and IMC Voltages)
HT V? Hypertransport Voltage adjustment for HT Input output signals
SB V? SB Chipset voltage adjustment ONLY mainly needed for increased stabilty of SATA I/O (Input/ output) stability (i.e. Raid Setups or multiple HDD)

Any advice would be awesome
OCing the CPU:

Pay most attention to the CPU Votlage (NOT VDD Voltage) for stability. increased HT Ref Clk may require more voltage to CPU than standard CPU Multi OC.

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!

I thought most overclockers using LN2 used "eraser"to insulate the board,gpu's etc etc,???

Or is that the "plastidipping"your reffering to,?

That sounds tough to do. Never done that before.

And yeah, putting on silicone sealer would a) be really tough cause it's thick, and b) would not peel off real easy.

Just another idea: ever thought about doing a hybrid? say, get you a baking pan big enough for the mobo...set it on plastic mounting inserts...mount your LN2 pots and all...fill the baking pan deep enough with oil to saturate to the bottom of the pots.

Think something like that would work? Then all you'd have to do is get some cleaner, clean the board, and let it dry for a couple days in sunlight I'd think.

Just some kooky ideas. Don't know if they're any good. I'd love to do cooling experiments tho.

Just don't have time

Thinking I'm going to use hot glue to seal the caps and chokes. It should be easy to peel off. Anyone know the thermal specs for hot glue? It'll probably be around freezing, 0c.

I'm contemplating the mineral oil idea very much. The only thing holding me back is cleanup after I'm done no the gpu's b/c I don't have enough pcie risers.
