Overclocking CONROE E6600 help.

[dVeLoPe]

E6600 L628 A269 EverCool WC-202
Gigabyte GA-965P-DQ6 BiOS Version F6
Corsair XMS2 TwinX Matched PC6400C4
Asus EN7950GT OC'd (7000 3dMark06)

I am at 367x9 = 3.3GHZ with a vCORE of 1.392 (CPU-Z) stable 4+ hours.. I have the vMCH,vFSB,vICH all at stock with my memory +.3 for it to get 2.1v but I am unsure why I cannot get past this FSB... My temps are 55-60c in CoreTemp and RightMark so I doubt it's cause of too much heat..
Should I have been upping the other voltages as well?
Why can't I achieve a stable overclock with a lower voltage? (1.376v or under won't run ORTHOS)
Should I overclock with a lower multiplier?

I will be happy with what it's at now but I was kind of hoping for a 50% overclock of 3.6GHZ.. Help me achieve my goal only 300mhz to go

Give it more juice....!!!!
Downlad Speedfan and do the chart thingy where you see live VCore and Temps...
I also use Core Temp and it's exaclty 5deg higher than Speedfan, but I like speedfan for its graphs... That said, I was stuck at 3.2GHz with 1.365 on the VCore. Anytyhing more and the stock Intel HS couldn't keep up. In ORTHOS it would be at 65deg after 5min. Changed to Hyper 48 (all copper HS) nad was able to raise vCore to 1.40 and get it up to 415FSB. Anything more and the memory gives up... It's only rated for 667MHz not 850 or more... Also I didnt have the balls to go over 1.4 on vCore, but after looking at the Conroe OC database (sticky) I saw a bunch of peeps with 1.5 and higher. One guy is up to 1.6V
Good luck.

Well I heard 1.4+ wasn't safe... I think I will throw 1.45v and see if I can get it up some more ..

Update your bios to F7 revision that may help out alot also bump up the Vcore to 1.40-1.45 (if you have good air cooling). If you have water cooling feel free to bump up Vcore +1.45-1.60 to get better results. Im guessing you will get your orthos stable 24/7 in the ballpark of 3.4ghz. If you up the vcore north of 1.45 you can expect to see 3.5ghz-3.7ghz depending on luck of the draw and effective cooling. I got a e6600 on a DS3 also. Mine is week 25. Im running it on watercooling at 3.55ghz with a vcore of 1.575v orthos stable. My chip starts to have big dimishing returns around 3.5ghz range. In my case to go from 3.55ghz to 3.6ghz it takes a jump of the vcore from 1.575v to 1.6v to have it going orthos stable. My e6600 idles at about 50c even according to core temp and goes upto 65c full load.

nullzero im not gonna get caught with being a noob once again.. I tried "FORCING" a F7 DS3 bios into my DQ6 motherboard already and it would fail to post hell even turn on. I managed to load the backup F3 bios back into it and now am messing with vCORE. I have a "cheap" watercooler but my temps are 40-45c iDLE and 55-65c LOAD @ 3.3*1.392v

The F7 bios for the DS3 was released on the exact same date as the F6 bios for the DQ6 so they likely are very similar with the equivalent updates for both.

No need to start cross flashing as you already learned!

Just lucky you were able to recover your Gigabyte board without having to try the RMA process with a straight face.

Most processors, including the AMD64, can reliably take a 15% to 20% core voltage increase.

Intel default 1.325 volts:
+15% = 1.52375 volts
+20% = 1.59000 volts

As always let stability be your guide. Keep an eye on CoreTemp and if you're Prime stable on both cores then be happy.

Yeah get a newer REAL bios for that board .

Also, tried setting the PCIe bus to 101mhz?

 

[dVeLoPe]

Nope.. I am about done with trying to overclock past 3.3.... I can't get orthos to be stable it just keeps failing on me. I have everything set to stock (AUTO) except for the 1.392vCore so I guess I will try locking the PCI-E to 101.. how about 100?

 

[Arcygenical]

Well, I HOPE you locked the PCIe buss to 100-105 before you started overclocking.

Sometimes the lock at 100 FUBAR's your OC, and you need to raise it to 101 mhz...

I'm assuming you also locked the PCI bus at 33mhz right?

As I recall, my Vcore for that speed was a little less, but it looks like you are hitting something similiar to what I experienced. Starting somewhere between 3.3 and 3.4 Ghz, I had to ramp my Vcore much quicker than for speeds below 3.3 Ghz. I recall seeing posts where others hit this as well.

Before you ramp your Vcore alot, I would suggest you try bumping the vMCH and vFSB by +0.1 and see if that helps.

You probably just hit the limit on your chip.

Consider yourself lucky as my e6600 only did 3Ghz.
3.3Ghz on a Core 2 chip is SMOKING FAST!

I wouldn't give more than 1.4v if you want to keep this as your main system 24/7. 1.5+v might be ok if you have great cooling (water or vapo) and you buy new chips every few months. (IE: if it doesn't matter if your chip dies in 6 months from overvoltage)

.....my temps are 40-45c iDLE and 55-65c LOAD @ 3.3*1.392v

That's with water cooling? Yikes... During my testing I've found that if the temps "spike" over 65c, the stability of your CPU goes WAY down quick... When I had stock cooler on, I would watch the SpeedFan temp chart, and have ORTHOS hammering my CPU, and whenever the temps would go over 65 (like 67~68), that's when I'd most likely get an error.. With the new heatsink, I never see anything above 65c (it hovers around 60~62)and that keeps my E6400 happy.
Keep it cool man...
