Q6600 >3.ghz

[SolMiester]

Hi all, I have G0 stepping Kentfield and are struggling to get any OC over 3.0ghz..Have adjust voltage to 1.365, but I get BSOD, or system reboots....Do I need to over volt other components too? CPU VVT, NB?...RAM is locked at DDR800.

Your help is appreciated..

Set your ram to 1:1. No chipset can lock it to a speed, it always runs on a divider.

Hi, thanks for replying, yes, Im using a divider to LOCK the RAM speed.....poor wording on my part!

I did notice setting to bump NB and CPU VTT (VVT?)..anyone have these bumped?

If you set your ram to run at 800 and have your FSB set to 333, your ram is running at 1000 on a 266 FSB chip. (5:3 ratio) If you set your ram to 667 and run a 333 bus on a 266 chip, your ram is running 833. (5:4 ratio) If you set your ram to 533 and run at 400 bus on a 266 chip, your ram is running 800. (1:1 ratio)

I'm running at 3.756v at 3.3GHz and was at 1.4v at 3.6GHz. I have memory set to 533 (1:1 ratio). Just set the lowest multiplier first and figure out your maximum FSB, then try increasing the RAM ratio afterwards (or leave the OC as it is).

What are your temps? I had to upgrade my cooling to get beyond 2.8GHz, I don't really like anything hitting 70C

The RAM is running @ 800 period, when I use 1.2 for 333 FSB or 1.1 for 400 FSB....When I select the divider, it shows the expected speed, so I'm not worried about the RAM.....

I haven't gone that high...it is stable @ 9 x 333 @ 1.325v, I tried 8 x 400 @ 1.365v, it got windows as far as login then restarted...
I seem to remember some users adjusting CPU VTT voltage!

You can work with multiplier or FSB . choose one. Put your voltage to 1.38v at your discretion it will get hot. increase mutliplier until X it with FSB equals to about 3.4Ghz

Or take down multiplier and work with FSB

You gonna know basic math skills. Take up FSB until FSB x multi equals your desired OC of 3.4Ghz @ 1.38v its gonna get hot, Im warning you again Im not responsible for what happens.

wait so what u do? I had my FSB set @ 367 and Ram set at auto, what should I set ram to if I want to run @ 3.3 ghz? Multiplier at 9. But occasionally unstable so does that mean I need to lower ram?

I was just suggesting you try it at the lowest speed possible to rule out the RAM speed going to high as your BSOD cause.

BSODs could be a lot of things.


Edit: and you can't usually be sure that BIOS will choose the most appropriate RAM frequency if left to auto - at stock it's nearly always fine, but RAM frequency sometimes goes too high with an FSB OC. I have a very similar setup (is your RAM DDR2 800 rated? or 1066? How many sticks, what size?) and I had to force 1:1 mem ratio to get beyond about 3.1GHz, so it is worth doing that as you push FSB higher.

plain and simple, your ram is failing - buy new ram

 

[Peter Trend]

When I wrote my previous post I thought Gloryfieldzi was the OP, my mistake!

plain and simple, your ram is failing - buy new ram

How can you be so sure? Incorrect RAM timings can make a system instable, as can so many other things, both hardware and BIOS related. I'm not saying bad RAM is uncommon but we should troubleshoot first. Particularly if the system works fine at stock, I would think the RAM is working.

If posters do suspect their RAM is defective for whatever reason they should try running Memtest as it may immediately get errors. But they will need correct BIOS settings to do so.

You can work with multiplier or FSB . choose one.

True. It is useful to find the highest FSB independently of the highest multiplier (test separately keeping one high and other low), but a choice can then be made to use either one or a combination of multiplier and FSB to achieve the highest clock possible.

@Gloryfieldzi would you mind starting a new thread with your problem so we can help you both more effectively?

what are the stock suggested volts and speed?

I remember everytime I played UT3 on a set of ram that I thought was fine, the game crashed.. never suspected the ram... sold my Q9650 for 150$ a year ago because i thought the chip was dying, swapped out 2 Gigabyte UD3R boards and the last thing I tried was a set of PNY DDR2 800 @ 1.9v - ran solid (this was about 2 months worth of aggravation, troubleshooting, different timings etc.)

Never put the RAM to auto. Choose from given options. If you mess with the multiplier you can leave ram on auto. If your going to take the FSB up then you need to take up your northbridge voltage. See if you can do 1:1 If not let it be downclocked a bit since FSB is gonna shoot it up.

Yes good post brother.

I hadn't heard of Memtest HCI, good to know :thumbsup:

The RAM in my case is running at stock 800...The temps are 38 idle at 3Ghz, Im sure there is room for more!

 

[BTRY B 529th FA BN]

so you have DDR2 800, what is the suggested stock volts?

 

[Spikesoldier]

try this for p35. are you running with all 4 dimm slots occupied?

vmch (nb) 1.400
vtt 1.375
vdimm 2.0
dram timing 5-5-5-15
dram divider 1:1

 

[SolMiester]

1.8v at 800 and 1066

vtt 1.375

Just 2 x 1Gb sticks...will have a look at those settings tonight and advise!

 

[BTRY B 529th FA BN]

do you have a link for that kit? for reference..

 

[tweakboy]

You can even go 2.0v if you have proper cooling. Try to keep RAM at 1:1 when your upping the FSB. 333 x 9 would be your speed.. thx

One of the main reasons I bought a q6700 was to keep the math simpler

Good luck on this, sounds like you have lots of experts here to help you out
