Q6600 B3: CPU, FSB voltage calculator? - Page 3

post #21 of 31
Thread Starter 
After doing alot more research and getting my ram RMAed, I am hoping my problem has been solved. I had a BIOS version that removed the SPP settings (NB) to avoid overclocking. I found the last revision that allowed me to change the SPP and these are my settings:

CPU Core: 1.4000
CPU FSB: 1.2750
Memory: 1.9500
NForce SPP: 1.4750
NF200: Auto

I have run more than 5 passes in IBT and no problems. (I also reached 75C max) However, my GFLops are only in the 32-33 range. I have set my Threads to 4 and my ram is set to 5100MB. (Task Manager showed 5196MB free)

Not sure if this is a good or bad thing, but I'm hoping after all the testing, I will finally get my system stable.

Well it looks like that didn't help either. I was just getting a bunch of blue screens. Even though I just RMAed both 2GB sticks for an exact matching pair, I am still having freezing/BSOD problems.

I tried using just the 2 2GB sticks alone and I am still getting freezing issues just trying to overclock my system at 3.2GHz. I have tried all kinds of settings, voltage changes, memory timings, linked and unlinked FSB/Memory settings, but it just doesn't seem like I will be able to OC this board with 2 2GB sticks. (Of course this might have to do with the make of the memory)

Anyone have any further suggestions? Would it have to do with the possibility that I just can't have a 3.2GHz OC with these modules and maybe lower my OC to 3.0GHz? If so, any settings to suggest?

Hi again, i am no expert but i will try

what multiplier are you using?
on my cpu, with a x9 multi, i couldn't get past 3ghz without it freezing.
so i dropped it to x8
if you set it at 400 x 8 (400mhz x 8 =3200 or 3.2ghz)
in my bios, my cpu voltage is 1.39v
leave ram alone, as if its 800mhz ram it will be at 1:1 with the cpu
(800/2=400mhz, and your fsb will be 400mhz as well)
also if you have anyother cpu voltage options (VTT or FSB) just raise them a couple of notches as well)
if this isn't stable, then try 375 x 8 = 3.000 or 3ghz

some chips are better at overclocking than others, so it could just be your chip

Thanks for the continued replies j.col.

I also had to have my multiplier at 8x. I still have yet to try at 3GHz OC, but I might have to give it a shot. I have my VTT at 1.4750 and FSB at 1.20 right now. (I'm on a B3 and seems to need more juice to be stable)

After more testing. The only time these 2-2GB sticks of memory seem to run stable on an OC of 3.2GHZ is when I change the suggested timings from 5-5-5-18 (or 5-5-5-15) to 6-6-6-18.

With timings of 6-6-6-18, I have it at 1.9v. (Although Wintec and CPUID shows I can go down to 1.8v. I tried going as high as 2.0v trying to go for the lower timings, but I still have not had any luck trying to keep my system stable.

If anyone has had this problem, would they suggest trying to go higher with the voltage on the memory itself (2.1v perhaps?) or am I pretty much stuck with these timings if I plan to keep this OC? Again, this is just for the 2 2GB sticks.

You seem to have a really bad chip. I know B3 aren't the good version of Q6600 for OCing but if you can't get stable over 3.0GHz that's really bad. Hope you made a mistake that would solve everything but it doesn't look like u did.

I also heard that nvidia chipset motherboard are dumb for OC.... Anyway. Q6600 G0 + p45 FTW

You definitely might be right about the difficulty of OCing a Q6600 B3 and a 750i board.

Tried a 3.0GHz mod and I seem to be getting issues when using Flash on Firefox and IE. Similar problem happened to me when I started using a 9x mulitiplier and/or not enough VTT/FSB voltage. I definitely dont feel comfortable going over 1.5v for my CPU.

The only thing I feel I have left to try is pumping up my memory voltage past 2.0v and thats another thing Im not sure will work fine.

i wouldn't go past 1.5v, its not reccommended for 24hr use.
if your ram is unlinked, then increasing the voltage, wont make a difference.
as billy mentioned, its probably your motherboard holding you back.

as i said before, i had an old g41 mobo and could barely get 3.0ghz stable.
i bought a p45 mobo and hit 3.3ghz in 5 mins and first time stable

you have a desicion to make,
1. keep what you have and leave it at that.
2. pick up a used p45 or p35 mobo ($50-$80ish, this forum has a for sale section) and then you may be ok upto 3.3ghz (or it may be your cpu )
3. or just wait and upgrade mobo, ram and cpu to i7 or sandybridge

Seems like you are right j.col

Once I change all 4 sticks and take them out of dual-channel position, no freezes, been running for hours and no problems what so ever. Once I put them back into dual-channel mode, my problems re-occur.

no probs.
glad you got it stable
what speed you at now?

I'm at 3.2 just like I want to be. I may start bringing down my voltage on my CPU to see if I can stay stable at a lower voltage and maybe try and bump my memory to 900mhz since I read a lot of people doing so with this memory.

Thanks for your help j.col, you have been multi-repped.
