Q6600 at 3.4gbz Help please

PLEASE READ LAST PAGE FOR CURRENT STATUS!

Thanks!

1.5v is fine make sure your never exceeding the temp threshold.

 

[purplemonkey]

thanks for the reply!

So what about my ram why isn't it running at 1066mhz?

 

[purplemonkey]

also anything past CPU - 377 like 388 and 400 fsb simply wont boot

TBH I'm new to this OC'in, and especially RAM, try following this but changing for your RAM latency.

AI Overclock Tuner: Manual

CPU Ratio Setting: 9

FSB Strap to North Bridge: 333

FSB Frequency: 333

PCI-E Frequency: 100

DRAM Frequency: DDR2-800MHz

(Or choose the nearest but under this as we don't want to overclock the ram

because then you'll have 2 components that may be unstable and then it becomes

harder to verify which is at fault. One step at a time)

DRAM Timing Control: Manual

1st Information

CAS# Latency: 4

DRAM RAS# to CAS# Delay: 4

DRAM RAS# Precharge: 4

DRAM RAS# Activate to Precharge: 12

DRAM Static Read Control: Disabled

DRAM Read Training: Disabled

MEM. OC Charger: Enabled

AI Clock Twister: Auto

AI Transaction Booster: Auto

CPU Voltage: 1.30000

CPU PLL Voltage: 1.50

FSB Termination Voltage: 1.20

DRAM Voltage: 2.1

NB Voltage: 1.20

SBridge Voltage: 1.10

PCIE SATA Voltage: 1.50

I recognise that as an ASUS board. I use one and iv read in a lot fo places the the volate calibration thing can overvolt your cpu briefly by up to .1v. While this may not be a hugee problem consider that this could put 1.6v through your chip briefly and *may* damage it. Im nto saying it will nor has this happened to me but this is what I've read. I found OCCT improves my OC slightly but if I dont use it then I can get away with less voltage : )

 

[°TheMadDutchDude°]

What stepping is your CPU? Is it a G0 or a B3?

1.5v is very high for those kind of clocks. Don't up your volts to 1.6, it will get very toasty! If you want my advice, tweak your RAM timings etc. Maybe up your NorthBridge volts a notch as well.

 

[purplemonkey]

trying a new tactic...

Starting with stock voltages on everything and working up to the limit for each FSB/voltage set currently working on 333fsb

to get stable then moving up

Only just realised when you highlight certain voltages in the BIOS it tells you what the standard voltages should be!

 

[purplemonkey]

is it true a failure an almost instantaneous failure in prime is generally due to ram settings?

 

[Bungral]

1.7v for benching

But don't do as I do... Because :iamwithst ... Take away the with.

 

[purplemonkey]

opps... spoke to soon

do i have a weak core it's always core 3 that fails prime

 

[purplemonkey]

is it normal after a failed overclock whereby it's booted to windows then bluescreened running prime - to then have to reset the cmos because all i get is a black screen when it reboots?

edit - my bad - lol after leaving it off for 30 secs it boots up to bios fine!

Ok i've come along since the last post -

Got a new Q6600

Setting so far are:

7x465 - Boots into windows but freezes under Prime95 after about 1 minute

CPU - 1.4V

NB voltage is 1.5

FSB Termination 1.4

All other voltages normal

Ram timings - 6-6-6-15 on pc2-85000 running at less than 1066mhz rated timings are 5-5-5-15

I don't think it's CPU voltage holding me back what else can it be?????????????????????????????????????????????????????????

 

[purplemonkey]

CPU set between 1.35 - 1.45 behaves exactly the same

 

[tinytomlogan]

not all quads like FSB tbh mate, Id say you are just getting to limits of the cpu.

anything above 450 stable on a q6600 is a billy bonus.

Drop the fsb and put the multi up now, see what you can get.

 

[purplemonkey]

dropped the FSB to 425 multi 8 everythings running fine just running prime blend now for at least 8 hours to check then i'll start trying to drop the voltages slightly... at the moment NB is 1.3 and Vcore is 1.4

thanks will keep u all updated

 

[purplemonkey]

just coming up to stable 2 hours prime with max temp during the two hours at 64 degrees set at Tjmax 90

 

[purplemonkey]

4 hours prime stable

Dropped the NB right down to 1.2 just checking stability with prime... the P5Q-E really doesn't seem to need too many volts unless your really pushing the FSB at the moment it's running 425 at stock voltage we'll see if it stays stable...

I think I'm beginning to settle for 3.4ghz OC 3.6 would be nice but the voltages really do shoot up for a fairly insignificant real world gain
