The Unofficial ASUS P5N-E SLI 650i Board Thread

[AZDude]

I just tried 1800/800 and was getting intermittent BSOD.

I have my Vcore set at 1.41 (whatever is closest to that) CPU-z and speedfan show it at 1.39. Should I bump it up?

What should I do then, exactly?

I've noticed in some previous posts that the BIOS voltage monitor isn't completely accurate, so can we even say with confidence that the 12V/5V rails are actually on the low side?
Also, as a general question, what's the deal with vdroop? Why do we worry about it?

The voltages are fine as long as they're within the 5% tolerance spec. Nothing important gets its power directly from the PSU.

I wouldn't even look at any of the BIOS readings from this board. They're so far off it's laughable, especially on the vcore and vmem.

Well thanks to dlxmax you can breathe a sigh of relief. Seems the bios is showing false readings. Its is always good idea if you suspect a faulty PSU to test it. Here are some reasonable priced testers PSU Tester

Try Auto vcore and Auto NB. That area can be a little tough. If auto doesn't work there. Try it at 1900/800

Thanks guys. I should have edited my post as soon as I caught up with reading all of the rest of the thread; you wouldn't have had to repeat yourself!

A related question that I didn't catch the answer to - Speedfan reports the same "false" readings. Is it using the same meters as the BIOS meters?

Yeah haven't seen him for a few days.

In other news I started overclocking my ram last night. I got it to 852 at 2.178v before I started getting memtest errors at the default 4-4-4-12 2T timings. Doing this at the 1560fsb bumped me off the 1:1 multi I was running previously and I lost about .3 on superpi even though the ram was running 70mhz faster Looks like I'd need at least another 30-40mhz before I'd make it back to even with the 1:1 time. But still, without jumping over the recommended voltage, getting to 852 isn't too bad, but I kinda expected a little more out of the ram. I only tweaked for about 40 mins, hopefully tonight I'll be able to play with it more.

Did you try upping the vdimm to 2.25

No not yet, its on the to do list.

Has anyone experience of this cooler? I am thinking it would fit on the Asus board better than a Arctic Freezer 7 Pro because it tilts. Possibly would not interfere with the NB heatsink? Only snag is I cannot seem to find this Intel clip in model in the UK? I have an Arctic Cooler 7 on order and it's not due for delivery until the 12th (Cheaper postage) so I could probably cancel and order this one if I could find it to buy in the UK than it.

EDIT: Oh well can't seem to find this particular model for sale in the UK so that's that.

OK, another question, when I put the Vcore on Auto it jumps the voltage all the way up to 1.49. This seems high, and raises my temps from 42 degrees idle to 47 degrees idle. Is that to high?

Set VCORE to AUTO will take you to windows (no matter how high you set FSB.. and probably run some app .. but (at least to me) would fail Orthor/Prime (dual)....

Like I mentioned ealier .. it could be my "bad" chip ....

 

[Derik75]

Alright. I just installed a new cpu heatsink (ZALMAN CNPS9500), new SB heatsink (ZALMAN ZM-NB47J), and attatched a suspended fan pointing directly on the NB. My temps have been lowered around 10-15 degrees. It looks like I am ready to start overclocking a little more. We'll see what this 6600 can do.

To fit it to blow out the back of the case. You have to trim the fan housing in the lower left hand corner with a heated knife or I used a hack saw blade and bend up the bottom fin up slightly to clear the NB its easy. pincers?????

From what I've read the arctic freezer 7 pro fan should be facing the ram slots and pulling air through the heatsink and towards the back outtakes on the case. Right now that is how I have it setup with the bottom fin pulled up slightly to clear the default northbridge heatsink. Been working great for me. Tell me if this is wrong. Love this forum.

I would say 1.38 - 1.45 should be enough. Use Auto vcore to get into window and it will give you an idea of what you need. Check speedfan and figure your vdroop then you can set a hard setting in the bios. Auto NB works well too. It actually runs cooler then if you set it at 1.56 IMO. Those screenshots I put up last night at 485x8 were with Auto Vchip(NB) and Auto Vcore ( about 1.45 - .03 vdroop idle = 1.42 idle in speedfan ).

 

[DeadMan3000]

The Arctic Freezer 7 Pro uses Arctic MX-1 thermal paste which hardens over 200 hours. Do you think this will work better for my concave CPU (If indeed my CPU is concave that is which seems likely)? Maybe it will fill the concave better than AS5?

Sounds correct to me. Fan should be facing towards the front of the case. Did you have to modify the plastic on the corner at all? Core2 did so I was wondering if you had a similar issue where the plastic part on the Freezer 7 was hitting the Northbridge heatsink.

Thats right. The fan should pull the heat off of you ram and create an airflow that takes it out the back of the case. It should also work to make a nice air stream being feed by cool air from your front intake case fan. I also have ventilation on the side panel of my case so I added a 120mm fan from the outside blowing cool air in on the VC, SB and NB. Plus I have two small chipset fans on the NB heatsink. Total fans are 3 120mm Fans, 2 40mm x 40mm chipset fans with a stock NB and a Zalman heatsink on the SB. That is why I think I can achieve those higher clocks easily.

Yes, and you can use a little more. It is thicker than AS5 and should stay where you put it better. They all take about 200 hours to cure. MX-1 is not conductive so you don't have to worry about seepage getting on other components

I have now put in a 680W psu, and i still got the mem problem?

any other ideas before i return this motherboard to the reseller??

The 1 thing that i think is odd. Is that, this problem came, when i changed from a 7800GT to a 8800GTS.

And i am getting mem errors :S

Is mem really the issue or is it something els? i am going to reinstall XP again to see if it helps. If not, then i am going to return this mobo.

But is there any GOOD out there, that can give me an answer to my problem?

 

[mantras]

Sweet, thanks for the clarification.

Yeah I got mine stable at 3.2 but I wanted to get a different heatsink for the NB and one for the SB before pushing. I think another fan in the front would help with airflow too. Currently my room is like in the 80s so that doesn't help... I think I will wait a bit to see this thing really move once the arctic winter has passed and we have our heat turned down. I do like to stay toasty when everything else is frozen
