Asus P5N32-E Overclocking Guide - Page 101

post #1001 of 5659
You definitely need a higher wattage power supply. Although possible, it's unknown whether the power supply is it fault for your instability.

I've had no luck overclocking with the P5N32-E SLI. Can't go over 1500FSB (no POST) and what I thought was a stable OC with a 1500FSB wasn't -- intermittent crashes. Board is totally stable at stock speeds, though, so I don't think there is anything wrong with the board itself. Other than, possibly, getting a lemon when it comes to overclocking. I decided to just sell it at a loss and get an ABIT AB9 Quad. It's weird, but every single ASUS board I've ever owned has been worthless at overclocking. It's like I'm cursed or something.

Definitely get a beefier P/S, though. That could be your problem.

Thats why its easy to have top hardware in the US and Canada.

Try doing it here!
Robilar and Cognoscenti

I've tried to get similar results you have have on your E6600 systems. The best performance I get stable is 3300@1466.7FSB@9Multi. I am using the p5n32-e sli with most of the spects. Robilar laid out in his guide (great guide, many thanks) except for: Corsair 8500cs5, 1 BFG 8800GTX, Antec 900 case, Zalman 9700, (2) Thermaltake Extreme Spirit II (north/south). My power settings are:
v.core 1.53125, mem 2.25, NB 1.4, SB 1.55, CPU VTT 1.55. Bios has been updated.

These are bios settings results:
@1490 FSB - Mem auto - No Post
@1485 FSB - mem auto - Failed Otheros Test within 5min - settings below ran Otheros for 4hrs no problems - highest temp 56 C.
@1480 FSB -mem auto - CPUMARK crashes/os reboot within 5min
@1475 FSB -mem auto - CPUMARK crashes/os reboot within 5min
@1470 FSB - Stable - CPUMARK06 results score 11176 CPU-Z rates FSB 1466.7

I have a Thermaltake PSU toughpower 750.

Any ideas to get better performance under air?

I was under the impression that having another SATA would in fact have the opposite effect i.e. increase boot time if every so slightly? How have I got this wrong?
As a follow up I can't seem to find any reference to boot up times being reduced. Did you time the difference Robilar.

Hi i have a similar system to Robilar, and followed his guide.

Asus P5N32-E SLi nForce 680 (Socket 775) PCI-Express DDR2 Motherboard
Intel Core 2 Duo E6600 "LGA775 Conroe" 2.40GHz (1066FSB)
Zalman CNPS9500-AT Aero Flower (Socket 775) CPU Cooler
OCZ 2GB (2 x 1GB) PC2-8500 1066MHz SLI-Ready Edition Dual Channel DDR2
BFG 800W UK/PFC Approved PSU

I followed Robilars guide and added the Two thermaltake coolers to my board, after removing the stock heatpipes.

I used the unlinked method and clocked my FSB to 1400 and my memory to 1066. Giving me a 3.35 Ghz overclock on my CPU, also using the 1002 bios.

The problem is i dont see any improvement at all in the benchmarks, should i? i am using 3dmark 06.

Does anyone have a similar system who can give me some help here? i have tried setting the timings manually at 5-5-5-15 and 4-4-4-8 but system then seems to become unstable and wont boot at times unless i hard power off and turn back, on at which point it tells me i should revert to defaults and reboot. I also tried setting the Memory Voltage to 2.1v but that didnt seem to help, what would really help me is for someone to take a look at my specs and give me some input.

(PICS ATTACHED BELOW)

I am willing to pay the person who gives me best results say $30.

Thanks in advance.

Rob just so you know I've had to up my motherboard voltages to get to 1995. I can't get 2000 just yet but I'm working on it. It will post but crashes at the window's loading screen. He's is what I am running below.
post #1007 of 5659
nice copper layout over you mobo! I love the look of copper and the Zalaman...

It's also nice to finally see someone that cut the pipes!
Question, why did you leave so much of it? were you hoping to avoid damaging the fins?

Whelp I can't figure out these voltage settings... My 3.49GHz wont get stable even with 1.6vcore. It will load into windows perfect, but if I even drop the SB voltage one notch windows wont load.

With that happening I am lead to believe it's my motherboard voltages and not my cvore. Should I really need to be increasing my SB over 1.7 to get 1990-1995 stable? I can leave all voltages where you describe in your guide and be stable at 1960 24/7 with 1.4vcore.

If I increase to 1965 I can't post. If I increase ONLY the SB I can post at 1970 which I am stressing right now with 1.6 SB and am 10 minutes in. I needed 1.75 SB to load windows at 1995 but couldn't get stable with 1.6vcore, 1.5 VHT, 1.65 NB. I think I am just going to chill out with 3.447GHz if this config is stable.

I'm afraid to run those other voltages that high. If you have any ideas feel free to share them.

Hi,

I'm pretty sure I've looked through all *101* pages and not seen what I'm about to ask for, but shoot me down if I've just missed it

I'm about to buy a P5N32-E SLI and plan on replacing the NB/SB coolers with a Noctua NC-U6 (NB) and a Thermalright HR-05 SLI (SB) unless anyone's had any bad experience with either of these.

A couple of questions first though:

1) I'll be putting a Zalman 9700 on the CPU. Will the airflow from this be enough to sufficiently cool the NC-U6 without additional fans?

2) Can I mount the HR-05 perpendicular to the direction of the graphics card? I'll try and illustrate this with a crappy pic:



That way I don't take up any of the middle expansion card area. I'm just not sure if the graphics card is too long to allow this. If no-one's done this but someone has an 8800GTX and could take the time to measure the distance from the southbridge (either side) to the end of the graphics card, I'd *really* appreciate it.

Thanks for all the useful info on the thread.

Stephen
