Q6600 and funky startup problems

[jeffw2767602]

Hey everyone. I have a Q6600 G0 and it is overclocked to 3.6GHz 9x400 1.44v completely stable for 12 hours of prime. Every once in awhile (like maybe once a week) my computer will start and wont POST. I have a Gigabyte p35-dq6 so the bios just resets everything to the default. I have since lowered my multiplier to 8 and everything seems fine. So why in the hell will everything the totally fine and then once out of every 9 to 10 restarts it wont post? thanks guys

I should probably add that my temperatures at 3.6 were in the mid and low 60's at load with a Thermalright Ultra 120 Ex.

whats the rest of your rig?

 

[jeffw2767602]

8800GTS 640 650/2000MHz
PC power and cooling silencer 750
gigabyte p35-dq6
4x1gb pc6400 crucial ballistix
seagate 7200.10 500gb

Something else I should add, the system seems to have more trouble restarting than starting up cold, maybe some part of the Mobo is getting hot...?Hmm.

Sorta similar issue here. I can't use the reset button cause when i do the board resets the overlock, otherwise have no probs. Don't know why it happens.

I have exactly the same problem with my DS3R. I duel boot, and when I reboot from XP to Vista, the board will reset itself. When I reboot from vista to xp, its fine. This is motherboard related not OS related, becuase it does it at the post of a reboot, not during shutdown of the OS. I was just about to start a new thread with this problem. I am running 3.3 and its prime stable. ~wonders~

BTW Jeff, those are some godly temps on air at that OC. infact, i have never heard of anyone OCing that hi on air. 3.4 is extremely good. If your using speedfan then your temps are at mid to high 70c under load.

THOUGHT: memory issue?

MORE THOUGHTS, a couple hours later: I noticed for me that Vista reboots to a full shutdown. XP only goes to bios and then restarts, screen never shuts off. I also believe for me it might be a drive issue, as I have some drives turned off in vista and also in XP. just more to think about.

Before you go out (save and exit) from BIOS, you need to save CMOS to BIOS by pushing F11, create a name (profile).
I was having this kind of problem before too (self-resetting BIOS even on light OCing).

Push a little up your FSB voltage and (g)MCH voltage into +0.1v. They give stability result. While you are doing this take care the temp of your Northbridge. Put a fan if possible.
If you are using a big heatsink or watercooling and you are sure that CPU temp never go beyond 60° on load, then you can disable CPU Thermal Monitoring (advanced options in BIOS) and CPU temperature monitoring (PC health in BIOS). Ignore the red blinking letters which said "system voltage not optimized" (MIT) or similar like that.

If there's an R.G.B. options in BIOS, put it on Turbo. It's to give wider bandwidth to your GPU card. I don't see any significant result, but gaining 2-4 fps on benchmark make me happy.
PCI-E frequency can be pushed into 101 or 102 and put the PCI voltage into +0.1v for stability.

No I added 15C. I am in a room with an ambient temp of around 19C (I likes it cold!) and my case has a big ass mesh window so the ambient in my case is pretty much my room ambient. Plus i lapped my TRU120Ex and my cpu.

Go to Xtremesystems forums and check out the air overlclocks for q6600's. They have people at 3.8ghz. Craziness

Ermmm, Wow, I think I will buy that HS. The scythe ninja is out of date.

As for the other guy who posted on this thread, our load temps always go over 60c. WC temps are usually about 50ish. Sooo, I dont think temp is the problem. I have an aftermarket cooler on my NB and it cuts that temp buy about 10c.

i will try the other two things, I just think its odd that it happens only when rebooting from XP and not Vista. But, i am getting close to exhausting all my resources here. Well, here is a question. What is the temp reading of the CPU in the bios? I mean, where does it read from? Cuase, its usually no where near close to the actual temps of the cores.

anyone else have anything on this topic?

 

[jeffw2767602]

Now that I've seen the new Penryn OC's I think I am going to push my q6600 to 3.8 at 1.55v . Maybe it will die by the time the Penryns come out lol. That will give me a good excuse to upgrade.

I FOUND THE PROBLEM........

I had an external HD hooked up via USB. Its one of those laptop internals with a housing that uses USB cable for the power as well. One of my favorite purchases, cuase, you do not need external power and I can move thru my desktop, laptop, other peoples comps and I do not nee dto ask them if the have external SATA conns. Anyways, what was going on was this.

XP boot = D:
Vista boot= C:

In vista I had the D drive disabled, in XP I had the C drive disable. And well, anytime you booted to XP (which I have not done in a long time since I was playing oblivion) it said "no HAL.DLL file, repair" yadda yadda. Anyways, there are some instances that found the USB drive to be C: whatever. So, i simply unplugged it and its fixed now..... Anyways, that is what fixed mine.

 

[boglwe]

ACtually, I still have the problem, just did it a few minutes ago. Does anyone have any suggestions on this. there are other people with this problem as well.

Just noticed that several of you with intermittent problems use 4x1g ram sticks. Try bumping your NB voltage a notch or two.
