Asus P5N32-E Overclocking Guide - Page 545

post #5441 of 5659
My PSU is a Coolermaster Extreme Power 650w. Link

It only has Two 6pin power connectors which are currently beeing used by the 9800 i have. i would have to run the other card on molex - PCI converters if i was to get one as it doesnt have the extra two.

That is a pretty low end PSU and at only 70% efficiency, I would pick up a new 750 by a more reputable manufacturer before you buy another VGA. Especially if you have multiple drives, fans and any other devices in your system already. It may perform pretty well with a new VGA at 1st, but after some time you will likely begin noticing both VGAs running hotter with a decrease in performance and lower FPS while gaming.

Hey all, first post here and a question about this board and overclocking with my particular system. Specs:

Quote:
Intel Core 2 Quad Q6600 2.40GHz 8MB
ASUS P5N32-E SLI LGA775 Motherboard
OCZ DDR2 PC2-9200 (1150MHz DDR2) Reaper HPC Edition (2x 1gb)
OCZ GameXstream 850W SLI PSU
OCZ Vendetta 2 cpu cooler
BFG 8800GT OC 512MB PCIe Video Cards (x2 SLI)
Western Digital Raptor 150Gb 10000Rpm WD1500ADFD (x2)
Microsoft Windows XP Pro SP3
I'm currently running the 1205 BIOS, which is just what happened to ship with the board. I've been desperately trying to get a decent overclock but having NO luck at all. I can get to 2.7ghz ok, and managed to get to 30.ghz last night but that was with my vcore set to 1.45v which seems a bit high. I've been leaving my NBvolts etc to auto as I only have the stock, passive cooling there and I'm scared I'll catch something on fire.

Also, I've got some OCZ Reaper 9200 ram in there (as per specs above) and have been reading about some apparent issues with certain this board, certain BIOS revisions and OCZ ram. As discussed here for instance though I'm not sure that applies to me, of if my RAM is even causing any problems with my so far failed overclocks.

What's happening with the OC is that as per the beginning of this guide, I disable the various things, like Speedstep and whatnot then set my mem voltage at 2.1v and leave the timings as auto. I then enter in an FSB to give me 3.0ghz (for instance) and typically get a failed boot (won't pass post) or I'll get to the BIOS loading screen where it says "hit delete to enter bios" but it will be hung there. I even get that at 2.7ghz sometimes, and even if I smack the vcore setting up to 1.45v.

So a few questions for anyone willing to help me out.
  1. Should I be upping my Northbridge volts, and if so to what? Do you suppose NBvolts to auto would be preventing me from getting any sort of overclock?
  2. Also if so, how far can I up it without worrying about overheating given my passive cooling situation?
  3. Is it advised to update my BIOS from 1205 to 1701, as I see that's the latest?
  4. Does OCZ ram cause any issues that might be the source of my problems?

ANY help is appreciated, I've been at this for days now and have gotten exactly nowhere. I'm reading through this thread slowly, but it's 540 some odd pages long.

Thanks,
datter

Welcome to OCN!
  • Yes, up your NB volts to at least 1.45.
  • 1.5 is safe if you have fair air-flow through your case. You could order one of these little fans and screw it right to the top of your NB heatsink for some added help. See pic below.
  • Your BIOS should be fine with your 65nm CPU
  • I've only heard good things about the OCZ memory on this board, but I don't use it myself. Updating the BIOS is easy enough. See if that helps
Also, go back and read the 1st post on this thread by Robilar and follow his recommendations per his pics and you should be set. 3.4GHz should be no problem for you. Many have hit 3.6GHz with the Q6600. Good luck!

Thank you very much for that, perhaps the core of my problem (no pun intended) was that I was leaving my NBvolts to auto. I'll look into the cooler thing too, I suppose that means I should actually locate my NorthBridge in there somewhere. I do have a spare 120mm fan I'm not using, I could always install that in front to pull cool air into the case. Think that would help? I've got a 120mm blowing out the back, and another 120mm blowing out the top plus the 120mm on the vendetta cooler itself. I guess more is always good.

I'd rather avoid flshing my BIOS, that being scary and all so I will try adding some NBvolts tonight, following along as the first post says see what happens. I've also read somewhere (maybe in this mighty thread) that the CPU VTT Voltage = should be 1.55v? EDIT: nm, I see it is in fact at the beginning of this mega thread.

At any rate, will post my results. Thanks for the encouraging words, I've been getting pretty discouraged.

ok, an update. After carefully following the first post in this thread I seem to have an overclock of some kind. The only thing different with the initial instructions here is that my NBvolts are at 1.45v instead of 1.4 as I believe it originally said. I am now sitting at a 3.0ghz OC, though my vcore is at 1.45ghz to get here. I left my ram timings to auto also, and set to unlinked with my otherwise speedy ram only at 667mhz as Windows was failing to load and I had to try something. Not sure it that did the trick or I just got lucky this boot.

Since I'm up for the moment I thought I'd post a pic of my HWMonitor info to see if anyone sees anything scary. Where exactly is my Northbridge temp in this?



I'm going to reboot a few times, the run some prime95 and see if this is even stable. Would value any feedback on where I am with regards to the above image, and how I might get to 3.4 from here.

EDIT: The above are all idle temps just to be clear.

Datter of fact, that's looking good. Bump your RAM up to 1066 for starters and keep it unlinked.

Absolutely put a fan in the the front of your case blowing in! It's a good idea to keep in the back of your mind roughly the CFM(air-flow) entering your case as well as the CFM as exhaust and try to keep them close to the same for maximum efficiency. As you are right now, you have some negative pressure inside your case. That doesn't mean anything for nothing other than those two 120mm exhaust fans are working harder than they need to.

Keep an eye on your SB temps too. A fast and easy way to cool your SB is to peel off that AI shield from it and stick a small VGA/chipset cooler on it with a bit of thermal adhesive. If you're not sure what is what on your MB, check out the link in my signature. There are many pictures identifying what's what in there.

Hey again. A bit of news.

I set the timings (5-5-5-18-2 clocks) as per the spec for my ram, and boosted the mhz to 1150mhz as lited, and couldn't get past post. I tried it with timings to auto, same result. I then left them on auto and tried 800mhz and got into Windows seemingly fine. After a bit of testing etc I decided to peer into my case for something and on restarting found I again, could not pass post. It would hang at the bios loading screen all over again. When I finally did get in I chickened out and reset factory defaults, so here I am at 2.4ghz again.

Now I may be able to leave my mem timings to auto and mhz to 667 and boot up again no problem, that was working fine before I started messing with my ram settings. That said, the reason I was peering into my case was to look into how I might arrange a Northbridge cooling.

I ran Everest and was appalled to see my Northbridge at 90deg and Southbridge at 60 or so. Thus, when I finally did get back into the BIOS I was rather keen to restore factory defaults until I sort out some cooling. Now having said that running Everest now that I'm back at default and I see my Northbridge is at 89 as I type this, and the South is at 56. I assume this has to do with the fact that my new tower cooler (the Vendetta 2) provides NO downward cooling at all, it's all horizontal out the back.

So, two questions for you or anyone willing to answer.
  1. Will I fry anything on this machine running it like this until I get a cooler sorted out?
  2. Will a small 40mm fan attached to the Northbridge heatsink help me out much?

Once I get my cooling worked out I plan to revisit this OC business, by trying auto timings at 667 and see how that goes, then I can sort out why I can't raise my mem values. For now, I'm all about cooling and rather concerned I'm going to melt something even at stock speed here.

Thanks.

ok wait, NOW I'm confused.

I just popped my case cover off and touched what I believe to be the Northbridge (on my rig it's a got a copper heat sink on it, right next to the main CPU. I could hold my hand on that indefinitely... it's just warm. When touching what I thought was the Southbridge (the one with no heatsink and a sticker on it) I found it got a bit to warm to touch after 10 seconds or more.

Maybe I have these two mixed up, best go look at those pics you talked about.

EDIT: ok, I think I was right... the Northbridge is up near the CPU as per this pic] correct?

If that's the case it's a pretty cool 90deg on my system, as said I can touch it indefinitely. Maybe Everest is giving me faulty temps?

ok, really sorry to be obtuse here but I want to be clear what I'm talking about because I think I may have this backwards. This pic is the same as my mobo... do I have this right?



If I'm right about that then Everest is about lying to me on temps, so how exactly does one go about measuring their north and south temps properly?

If I'm indeed backwards on this and have the two mixed up, then Everest might be right as it's telling me my north is hotter than my south... so would 90deg fry anything until I sort out some cooling?
