Help, Q6600 refuses to POST after OC.

post #1 of 10
Thread Starter 
Hello all. I recently had a port issue with my old mobo that caused me to get a new one, and with my new mobo, no matter what i do, if i alter my clock settings in any way shape or form, my computer will not post. I then have to turn off my power supply, wait, turn it back on, it will not post again, the third time it will tell me posting has failed and ask if i want to enter setup or run defaults.

When i run defaults, everything is fine.
i currently have a Q6600
Asus P5q Turbo
Nvidia 8800GT
8G ram

i'm looking at getting back to what i was running before, which was 3ghz. which should be as easy as pie but for the life of me i cannot figure this out. I'm hoping someone a little more savvy than i will be able to help me with my posting issue, so that i may try to OC my box again.

I like having my machine OC'd because i am an event photographer. My machine is used in a studio setup and it helps a lot when i run lightroom because there are so many large files at any given time open.

Perhaps there is some sort of troubleshooting i can do, but im just not sure what it is haha. Thanks a lot!

Okay bro. Sorry but I'm not pro at this but I will try my best. I recently had this set up.

Q6600 2.4 OC'd to 3.2Ghz
8600 GT 512MB
2GB 800 Kingston RAM
550W PSU.
MSI P35 (Yours is better)

My overclock was stable at 3.0Ghz | 333 | 1.2750
Then went to 3.2Ghz | 400 | 8X | 1.3000

Everything is fine and running good as it should then I replaced my 2GB with a 2X2GB Team Elite I started having so much problems I kept getting BSoD and restarts and freezes. Of course I was on 32bit Windows 7 then moved to 64bit to use the whole 4GB ram so what help I got from someone is to set the RAM timings to default and that is what helped me. Maybe your RAM timings are set to "Auto" for example what I saw on the sticker of my RAM was the timings 6-6-6-18 but on Auto it changes it. So I manually set it to 6-6-6-18 like what was shown on the sticker of the RAM and now I don't have problems. You have a better motherboard which makes it better cos 3.0Ghz is easy as pie.


Edit

One more thing. Try picturing your BIOS where you see the multiplier and the rest of the settings where you overclock. I'll see what I can do to help you. There are some things you need to disable and off.

Exactly what are you changing in BIOS?

Yeah. are you forgetting to up the voltage or not lowering the ram timings back down after you raise the fsb?

i was just changing my fsb at first. i couldnt figure out how to find what voltage my cpu was running at, cpu-z says 1.325, but i knew it shouldnt be that high. that was on auto setting.

my problem was i diddnt know what voltage to start with, so i was kinda going in the dark, haha. my ram timings are auto, they are 5-5-5-15. ill set them in manually and see what happens right away here.

yeah it was on auto, it wasnt correct and crashed on me, i could only get it to sit at 2.7 for an hour or so, then she would go down.

thanks for the help! im off to make her beep more.

i found this.

Ai overclocker tuner.............manual
COU ratio.............................8.0
FSB freq...............................400
PCIE freq.............................101
FSB strap NB........................auto
DRAM freq............................961MHz
DRAM timing.........................auto
DRAM static read..................disabled
DRAM read training..............disabled
Mem. OC charger.................auto
AI clock twister....................auto
AI transaction booster.........auto
CPU volt...............................1.40

CPU and NB, should they always be the same?

most of my settings are on auto still.


CPU PLL volt........................auto
FSB term volt.......................auto
DRAM volt............................2.0
NB volt.................................1.40
SB voltage...........................auto
PCIE SATA............................auto
load line calibration..............auto
CPU spread..........................disabled
PCIE spread.........................disabled

advanced menu settings;
C1E support.........................disabled
Max CPUID value limit..........disabled
Intel vurtualization...............enabled
CPU TM.................................enabled
execute disable BIT..............enabled

currently sitting at 2.7, at 1.15volts. i tried going to up 333fsb at 1.275 but no luck yet. if i were to go up any given interval on my FSB, say 10, how much voltage should i expect to go up?

CPU and NB volts don't need to be the same. I'd leave NB at 1.4 for now. I'd put the Multi to 9, FSB to 333, and core voltage to 1.375V to start. Q6600's are good to go up to around 1.55V with proper cooling and temps. Make sure your RAM is unlinked and running at default specs/volts too.

Turn off CPU TM
You're setting FSB to 400, which would be 3.6GHz on the proc. 1.4VCore is likely way to low for that speed. If you're shooting for 3.0GHz your FSB should be 333 and I doubt you need more than stock VCore or 1.35-ish.
Your RAM is out of spec if it's DDR2 800. If it's 1066 then it's OK.

that will not let my pc post. i had it running at 300fsb for a bit, and im having troubles getting it back there. ram was at default timings.

no no these arent my settings, i just found them to compare to. i was using those as an idea of what to disable/leave on auto. i used that as a guideline, and it diddnt work either. lol.

if i put it up to 300fsb and 1.18vcore, then try to go to 333 at 1.275 as the other guy tried, i get nothing, or 1.325, nothing, or 1.35, nothing. always reverts.
