Q6600 - no joy overclocking

[Fitseries3]

680i does have a FSB hole or 2 or 3 or 4. i've found one at 390-420mhz and i believe there is one around 325-350mhz. you may try 9x 360(1440) with the vcore at 1.425v

Im using the P30 BiOS with my board, most stable bios yet for my q6600. jsut a though Bios wise. Might be the bios, i know that at the EVGA forums they expiermenting with XFX BiOS, and said that P30 is more stable than P31 in terms of a quad core, i don't know if this carries over to BFG tho.

Still having troubles. I still think its the RAM holding me back though. Anyone using the sam RAM with a Q6600?

I have reset the BIOS and am currently running SLI-Expert Mode, Unlinked, 2.8GHZ CPU and 1066MHZ RAM with preset timimgs 5,5,5,15,2T and have no stabaility issues what so ever. What the hells wrong!

 

[pepsi71ocean]

i think u need to tighten up ur ram timings, i did better with tighter timings.you might want to bump your ram voltage to 1.9 It might be the ram in undervoltaged.

EDIT: whats the mobo's ram speed rated at? 800MHz, or 1066?

 

[CrAsHnBuRnXp]

only the older 680i's have that problem. the newer ones such as my 2 evga A1 boards have no problem with quads. my q6600 runs great.... pics are proof...

I have an A1.

 

[Fitseries3]

I have an A1.

isn't your quad a b3 though? it should be able to get to 3.4. if not, something else is holding you back.

 

[francis511]

The 680i boards usually dont go past 3GHz with quad cores unfortunately. Thats one reason I just bought an x38 chipset. That and Yorkfield support and PCIe 2.0.

I run linked and syncd. FSB is 1337 of all numbers. 3Ghz Prime64 stable. (I use a 64-bit OS)

I heard this was quite common

Put your vcore on auto number 1. It will scale with higher clocks.If your at a 1067 on ram, get the hell out of 1t. Set to 2t. Your way low on vdimm. Up to at least 2.1 vdimm. Back down on fsb termination voltage, 1.4v is not needed. Its your ram thats holding you back. You cannot do 1066 at 1.85 vdimm.

try this ^ it's just a rough outline to get you past the wall.

Raise the memory voltage to 2.0, CPU voltage to 1.350v, run linked with the memory 1:1 at 333x9 (ram at 667, 3GHz CPU speed)


To be honest, you shouldnt be BSOD'ing at these levels.

You mentioned water - have you made sure its working and all temps are good? Are you sure all FOUR cores on the CPU are fine, and not just the overall temp? (verify with coretemp)

 

[CrAsHnBuRnXp]

isn't your quad a b3 though? it should be able to get to 3.4. if not, something else is holding you back.

Believe me, Ive gone through this a million times. On HWA, on TPU, and on EVGA's forums. Nothing. It just wont.

I do have a B3 stepping and anything above 3Ghz, gets to hot during prime to continue any further. When I get my new motherboard, I will see what I can do if anything at all.

try a p35 board and a better cooling setup. or just sell the B3 and get something new like a e8400 which will be the new OC king.

 

[CrAsHnBuRnXp]

I just bout an x38 and I will be getting a Q9450 around the time of release.

x38 is good. i don't think the new quads will be that great. either get a G0 65nm quad or a e8000 series. the e8400 can run 4.5ghz and bench like a q6600 at 3ghz.

 

[CrAsHnBuRnXp]

Im pretty set on the Q9450. I love my Q6600 despite the lack over overclockability. Im not about to go from a quad core back to a dual core. After these last two upgrades, I want the computer to last me a while. I have been on an upgrade rampage for the last year and a half. Time to slow that down drastically. If the 45nm chips are supposed to be cooler (from what a guy on here that said he had 15C idle temps on a stock cooler but with a factored in room temp) and are on par with the current quad cores from Intel (price wise) I might as well just get the newer offering.

This is your ram. Run it at specified timings and voltage.

 

[Dia01]

try this ^ it's just a rough outline to get you past the wall.

Thanks fitseries3 but still doesn't hold stable what so ever. I can hold rock solid at 2.8GHZ with 1066 RAM though. Any increase above that she's all over red rover say hello to the BSOD. I have tried every concievable memory timing, voltage increases, linked with sync, 1:1, 3:2 and 5:4, unlinked and manually adjusting with 667, 800 and 1066 for the hell of it. I must admit I don't know what the Advanced Memory options are though, could this be the cause or do I just accept 2.8GHZ?

 

[Fitseries3]

never let your computer tell YOU who's boss. you CAN get it to run better. you just need some time to better understand what everything means and how it effects the way other things run.

2.8ghz is not acceptable for a q6600.

 

[Mussels]

its possible his mobo is at fault here.

Have you tried raising the motherboard voltages? (northbridge etc)? tried rasing them to MAX? just to see?

I have tried raising the voltages to max except the CPU, the furtherest I've had it is 1.475V and cooling isn't the issue either. I still think its the memory but.

 

[grunt_408]

Have you tested the memory at all?

 

[Dia01]

Have you tested the memory at all?

At stock settings the memory is fine although these particular types are quite sensitive and litterally a pain in the a$$. I think I just got to figure out the best settings for them. I'm trying for 4.875 Vcore, 1.5V CPU FSB, 2.3V RAM, 1.5V SPP and running Prime95 again. I've locked the timings to 5-5-5-12-2T.

 

[grunt_408]

you are having a real tuff time O/C that thing man If mine was that hard I would get the $hits with it.
Have you ran memtest?

 

[niko084]

that's a 6750 for ya.

e6750 is a goofy chip...
Mine goes to 3200 @ 1.2 volts no problem...

To go above I have to kick it to around 1.5 volts and then it will go to
at *least* 3600, have not pushed for more but it was stable there just
didn't want the temps for so little.

Multi hurts.... But ohh well 3200 is screaming to be honest.


******************
As for your ram, what frequency are you ending up running it at?
Try like 5-5-5-15 or 6-6-6-18 at 1:1 timings and then go for 300-325-350-375-400 FSB run ram voltage @ 2.1-2.2...
2.3 is getting a little much for most DDR2.
Get your processor voltage up to around 1.475-1.5 maybe a bit more.. Quads love power.
May need to boost your northbridge voltage a bit.

 

[Mussels]

my e6750 in storage takes 1.375v for 3.2Ghz. wish it ran 1.2 like yours.
