Asus P5N32-E Overclocking Guide - Page 407

post #4061 of 5659
Ok Hardware Guru's HEre is a question for the more enlightened.
I found that my computer has less issues if I underclock my RAM Freq to 800Mhz. I know the ram is ok, but is there maybe a memory controller that it causing issues?
I currently am using 2.0v Ram and 800mhx, even though it is rated to 2.45 and 1000mhz.
Up until now I have used the stock 9x multiplier and upped the FSB.
If I was to overclock using a 13multiplier and keep the stock FSB numbers would that give some idea as to what the issue is? Is that less stressful on some of the MB components?

Hi! I don't think your mulitplier is adjustable upwards. Correct me if I am wrong, but the only way to OC on that cpu is to up the FSB.
post #4063 of 5659
Nicoloco, I understand exactly what you mean. The SB is the same as the NB and is a small chip.

Shizam, Nicoloco is correct. You can't increase your multi; you can only lower it. Only extreme (with an "X" in the name) series processors have unlocked multis (often, this is the only difference besides the price tag that is between 3-4 times higher).

You shouldn't HAVE to run your RAM at 800, but if you want to for stability, you might be able to squeeze CR1 and tighter timings to compensate for the slower speed.

Example, compare the RAM bandwidth between these two combinations:
9x400 for 3.6 and RAM at 1:1 (800), 4-4-4-12-2T
or
9x380 for 3.42 and RAM at 1:1 (760), 3-3-3-9-1T

Incidentally, you are running UNLINKED, right?

HI
I am running unlinked and used all the settings in this thread to setup my first OC on this machine.
I haven't tried to up the multiplier. Too bad it wont work.
I just rebooted. it took 4 tries to get it to post. Running in the sos recovery mode, my system just ran prime95 for 2 hours. I am still working out where the problem is but I am thinking it must be the board.

With a higher than stock FSB freq, what other than northbridge has to handle more heat?

There is a 1302 BIOS on the ASUS FTP site for P5N32E-SLI.

Anyone tried it yet and have any opinions ?

CplRusty:
It's been out for a number of weeks if not months. Litlratt & I tried it. It's utter crap for OC.


Shizam:
Running in recovery mode is worse than running everything in AUTO on stock. It chooses overly safe values. Stability in an UNDERclocked (let alone stock) condition should be taken as granted.

Because increasing FSB requires greater vCore and vNB, both CPU and NB need cooling. To answer your question, the other components that will need cooling are the mosfets or VRMs (Voltage Regulating Module) located around the CPU socket (there are eight pairs). These are covered by the stock heatpipes and need some protection if you've removed the stock NB solution (if you want, you can cut the pipes and use the stock mosfet HS by itself, just reseated with some thermal tape... see my sig for free stuff).

Your situation sounds very dire, and I think dire measures are needed. You should consider all or a combination of the following. If they look familiar, it's because a number of people have suggested them before:

1) Reset CMOS and restore BIOS defaults
2) Reformat/reinstall Vista
3) RMA your board

Do these things in order, but don't bother with #2 if you're still failing POST... skip to #3.

Tried it and reverted back to 1203.
You have the best overclocking BIOS in my opinion.

Thanks Dosto and Littlrat... I'll stay where I am with 1203 since I am happy with my OC.

You check your memory?What volts you have for those sticks?

Alex The RAM is at 2.3volts right now. It is OCZ VXtreme rated to 2.5 max.
I have the timings all set to stock to isolate the problems.
I think it is time for an RMA. Anyone know where I can buy a stock NB heat pipe?
