q6600 overclock

[Dr.Sadin]

Hello Guys!
I wanted to push my q6600 a bit, and overclocked it to 3.2 ghz (400 x 8), but when i saved and quit, it said that my overclock was not successful. So i lowered it to 2.9 ghz (375 x 8) and when i started it, i had round 3.38 ghz, which is more than i expected (crushed after 30 mins of nothing - basically minecraft and mozilla).

 

Rest of configuration: 2x 1gb hynix ddr2 pc2 6400u and 1x some sh*t ram 2 gb pc2 6400, set them all @ 5-5-5-15 1.80v
                                   Intel Core 2 Quad q6600 @ 1.30v

                                   Asus p5q Deluxe

Can anyone explain me what is causing the problem (higher cpu clock as expected), and how to solve it?

 

---RIGHT NOW---

Im running it stabile on 3.01 ghz (333 x 9 - which should be 2.997, but not so big problem tho) @ 1.30v with same memory clock @ 5-5-5-15 1.80v

Memory clock ratio is 4:5 (x1.25)

ran prime95 on this setup and got 72C (Blend)

nothing else was changed.

I have an old Q6600 that used to run @ 3.6ghz 24x7. Like a castrated stallion it now runs @ 3.3ghz. The 775 motherboard has jumpers. Make sure your jumpers are the 333mhz and not the 400mhz. I think there is also a 200mhz jumper setting as well. change your memory timings at that high one to 50. So 5-5-5-15 and the big one from 45 to 50 on the timing. 

 

Before making those changes crank up the party on your CPU to 1.35v and see if that gives you the stability that you are lacking.

Ok so ive set it to 1.35v and 375 x 8, in bios it says 3.01ghz, hwinfo-> 8 x 375 = 3000 mhz @1.2125V(which is default 2.4 ghz voltage), and (Windows 10) system info says im clocked at 3.38ghz (together with task manager), and cpu-z says 1.344V but cannot find frequency other than 2.4ghz (stock) in specifications.

Bios says im on 33celsius, realtemp says im on 45 (cores: 46, 44, 44, 40), and hwinfo says its running on 28-30 celsius, but in cores it says 36, 34, 34, 30

(pc was idle whole time tho)

 

Prime95 small FTT test (6 mins)

     No crash

     Realtemp says 75 celsius on all cores

     Hwinfo says 65 on all cores

     (btw case was opened)

 

Prime95 Blend test (6 mins)

     No crash

     Realtemp says 74 74 72 72 max 

     Hwinfo says 64 64 62 62

     (case opened)

 

Who should i trust in temp, voltage and clock?

Hwinfo, realtemp, cpu z, and system telling me different stuff... No SINGLE thing that they stay together with.

Update: 

-Updated hwinfo to newest version, still showing 10 celsius lower than realtemp.

 

-Starting minecraft, but its crashing and in log it says that cpu is unknown.

Ok so i shut down pc, drained Power for some reason, and turned on pc...it turned on, lost Power, and turned on almost 5 seconds later..

Did that without Power draining, started with no problem, drained Power again, its doing same thing with Power loss.

Booted pc fully, its Starting with 320x640

 

Edit:

Took cmos battery out, everything is normal, even that Power loss thing...

Graphics are fine, clock speed is back @2.4ghz in bios but system still reads 3.38ghz!!!

Hwinfo reads 2.4ghz

Minecraft STILL CRASHES (probably because Windows is false reading)

I feel like this pc doesnt like me at all ???

Im giving up from Overclocking till Next time, but till then im gonna run on stock clock, and try to remove this 3.38ghz from my system.

 

Thanks for help,
