Increase chipset voltage if necessary.

So I tried the following settings and these are the results

400    2.00     9         Loops back to Bios and eventually reverts to 200 FSB
378    2.00     9         Doesnt even load up, reverts back to 200 FSB
370    2.00     9         One BSOD but kept restarting after the Windows screen

I'll report back after I've tried to increase voltage.

Edit
Default VCore is 1.325

My most stable settings have been Default Voltages FSB 320x10 @ 2.5 DRAM multiplier. Any other suggestions to improve would be awesome. Thanks

Got mine and lovin it!

Q6600 G0 - 3.4ghz - 378 fsb - 1.4 vCore (1.28ish with droop). http://valid.x86-secret.com/show_oc.php?id=275724

I got some Prime95 errors at 3.6, 3.5 was stable for the 30 minutes I tested it for at 1.45 vCore so I'll probably test that more later.


How can I adjust the memory timings with this board (or can I)?

At the main BIOS screen hit CTRL and F1. Then go into M.I.T. and there it is.

Also, the CRTL + F1 trick will unlock some other things in the other catagories as well.

Just got this board with a 2180, but it seems I can't get past 3.0ghz (1 hour orthos stable) but to get there I need 1.475 vcore, and I get a horrible vdroop of 1.424 on load. I've tried 320x10 on 1.5 and it BSOD once I boot into windows.

Also my temps seem to be insanely cool, coretemp reads 28c on idle and 51c on load. Do you guys think this is accurate at all? This is with 300x10 on 1.475 volts.

I'm not sure if I should try for a higher voltage to try to get 3.2ghz since my temps are pretty great, but like I said, I'm not sure if coretemp is accurate or not.

Edit: Forgot to mention I'm running a Thermalright Ultra 120A with a Scythe 1200rpm Slipstream.

If I am running my FSB at 395-410, do I need to increase the FSB and NB voltages higher that 0.1+? I am new to Intel and just got a e2140 and this board to try it out. What is a safe max temp for these cpu's? I am hitting 56C loaded with stock cooler.

I fail orthos at 400*8 and tried upping the NB and MCH to 0.2+ and the CPU to 1.316ish. Form reading this thread, it looks like the CPU is what is causing the instabiklity as some of you have reached much higher FSB speeds with no volatge change.


Also, I have one temp in speedfan (temp2) that gets to 60C when stress testing. (it is getting hotter than the cores) Whattemp is this? I had thought NB, but now I am not sure. It is the only thing that makes me nervous.

So far, great board. Posted first try and everything is running fine so far.

Wow, lots of new questions.

Try increasing your FSB AND MCH voltages by +.2v, and give your processor 1.4v. Also, what memory do you have? You should list that in your system specs. That may need more voltage as well... try +.2v on that at least.

THEN, when you have those voltages set, start at 330FSB, make sure it'll boot to Windows, then increase by 10mhz (to 340FSB), and so on. Don't just jump up to a particular setting if you're having trouble. Give that a try and report back.

Great OC! Put you on the list.

The vdroop is terrible on this board, but that should be fixed in the F8 BIOS. That seems like a ton of voltage to get the chip to 3.0ghz though, but maybe you just got a dud. You could try reducing the multiplier and increasing the FSB, sometimes that helps stability with these chips, and it might help you get higher. What is your memory multiplier set at? It should be set at 2.00. What are all of your voltages set at right now?

The temps seem about right for that cooler. The 2180 (and many other C2D's) doesn't get real hot under good coolers until you get up to 3.6ghz or so.

So far, great board. Posted first try and everything is running fine so far.

I didn't need any more than stock voltage up to 470FSB, so I would guess that you're probably fine. Don't go over 60c load as far as temps, but those are pretty good temps for your speed.

Reading through the rest of your post, it's likely that your CPU needs more voltage to go higher. You're actually undervolting it right now, as default voltage is 1.325. You'll have to be very careful of your temperatures while increasing voltage since you just have the stock cooler though. Take small steps, and see how far you can go. I would up the voltage to default, see how far you can go, and check your temps along the way.

Thanks. I have a few more ideas after surfing all day (slow day at work, lol) Do you have any idea what the temp2 is in speedfan? It is hitting 60C when loaded (hotter than the cores) and that is the only thing I am woried about. I can see that going over 60C by just increasing to stock vcore.

Forgot to mention my volts. I have MCH at +.01 and DDRV at +.02, I've tried increasing my MCH to +.02 and FSB to +.01 and still no stability. I highly doubt my DDRV is the problem since I'm overclocking on very relaxed timing right now, just so I know my ram isn't the problem. I'm also running on the F6 bios, I wasn't aware the F8 is out.

I'll try to lower my multiplier and increase FSB. I started orthos this morning and it's going 10 hours now on 300x10 so it seems it's very stable. I'm happy being able to get to 3ghz but yeah, the voltage seems a bit high.

Thanks for the help.

Edit: Forgot to mention my memory multiplier is 2.00

2 new highs for me on my wife's rig:

New 24/7 OC:

P95 Stable for 8 hours
3.303GHz 9x367 with vcore at 1.425 / +0.3MCH / +0.2FSB
5:6 FSB:RAM ratio Corsair PC-6400 @ 881MHz 4-4-3-11 2T

Tjunc (Core) temps top out at 68C under P95

New high:

3.600GHz 9x400 with vcore at 1.475 / +0.3MCH / +0.3FSB
1:1 FSB:RAM ratio Corsair PC-6400 @ 800MHz 4-4-3-11 2T

I could not get the 3.6GHz to stay stable in P95 for more than an hour or so. Vdroop is brutal Does anyone know of a pencil mod for this board by chance?

[Skydawg]

Greets oc brothers,
I would like to know if anyone can help me refine this overclock. Here are my cpu-z captures attached. Couldn't figure out how to imbed them. Let me know if you need more info.

Thanks,
John
