:confused: hi everybody, im new here, and im new with intel processors.
i bought a new system and my choice was the 6600 processor and after looking for a good motherboard i found the quadgt. i bougth i pair os OCZ 6400 platinum revision, this one advice by forums. ahhh, and a 8800 gts 320mb. im using my tagan modular (515- u) with 530w.
First impression was not good since was very difficult to install my 2 raptors in raid. im using the last beta bios that the link was provide in this site.
Ok until now, everithing was working, but was time for some benchmarks before do overclock. I just run the everest to run cache and memory benchmark an when start to run l2 cache, stops and the system crashes.
After talk with an engenieer he told me to change the memory timings to same values of OCZ (4-4-4-15 in that case). Go to bios change and computer dont want to boot anymore. i had to clear the bios.
Now ive checked with cpu-z the timings that is runing, since i left by the bios decide this, and is 408mhz 5-5-5-15 2t timings.
Can anybody say whats going wrong??? why my system is crashing(and if the engenieer is rigth to change the timings), and why i cant boot after change the timings on bios.
thanks!!!!
 
Got the same ram and running at 4,4,4,15 @850mhz. Like me however, you may need to set the Ram voltage manually @2.00 volts. Give this a try. (my system also would boot with voltage on auto. ;)
 
Should also say, can't get my system to post for love or money with a 1T command rate. Got mine set at 2T. Don't know what the solution is here.
 
Test it by slowly increasing the FSB, and running bencharks and stability programs. Once you find a setting is stable, make a note of it and press for more. With your e6600 it has a x9 multiplier so when u reach 400fsb (after slowly getting there), the cpu frequency will be 3.6Ghz. I wouldnt recommend jumping straight to that because its likely to need a vcore increase, and thats if u have a decent cooler too.

You might find that people suggest upping other voltages for fsb and north bridge, but since I dont have your board I cant recommend exact settings.
 
thanks megatron, and what about my memories???
its an ocz 6400, wich divider should i use and wich temperatures are safe?
 
Since its a 965 board u should run it at 1:1, other options are to run the memory with a faster divider. Temperatures ideally shouldnt go above 65'c, especially if u want the overclock to remain stable in hotter weather. Absolute temperature limits depend on the specifications of the chip, but when overclocking you want the temp to be as low as possible.

More relevant I think is what is the highest vcore you should use (which also depends on the type of cooling i.e. air, water, phase), you will get varying opinions on this but Ill leave that to someone who has a core2duo to answer.
 
ok.
running now at :D (hope go little more)
3060 mhz (using arctic colling freezer 7)
bus speed 340mhz
fsb 1360
ram 425 mhz 4-4-4-15 2t and voltage set to 2.1
nothing else! until now no erros.
idle 39c and full using orthos go to maximum 59c - 65c.
any comments?
tks again.
 
The ram is running 1.25 times faster than the FSB. Chances are that you will hit memory instability before cpu instability, when increasing your overclock. There must be a setting to do with memory clock that needs to be changed.

However its stable now and its a decent overclock already, but Im sure u can get more.

Id keep an eye on the temperatures though, if u have your cooler on right, and still at default voltage you should be fine. Maybe the temperature sensor is reading high.
 
and how to do that, since i only have 3 dividers olny in the bios? :rolleyes:
and now is strange, i put at bios multiplier 8. Somehow, i dont know if is normal, when i start cpu-z stays multiplier 6x in idle and goes to 9x when full, can somebody explain that?

should i change this memories for OCZ 2GB(1 x 1GB) Kit 1066MHZ PC8500(OCZ2N1066SR2GK), since the mobo specifications says support only ddr2800???

Your RAM is fine.

Im not the best person to be answering your questions cause as I said I dont have a 965 board (yet). However I can tell you that you need to turn off Intel "speed step" in the bios. Anything related to power saving and speed changing, like c1e. I cant be more specific cause Im just relaying what Ive already read in other threads.

Default multiplier of the 6600 is x9. I would take that as an advantage since you will probably hit CPU instability first and then you can see if its possible to drop the multiplier to get a higher ram speed overclock with your max cpu overclock.

If u have 3 options in the bios for memory speed then its going to be easy to find which one you need by keeping a default FSB and then changing them and looking at the results in windows in various programs like CPU-z. Alternatively you could have mentioned the settings names and let me guess. :p

there is, set the 533 divider which will run 1:1 with the CPU.
 
tks for reply guys!!!
solve the problem with Disable C1E/ speedstep. Tricky bios!!!
now is like this:
core speed: 3.2 ghz
multiplier: 8x
bus speed: 400mhz
divider : 1:1
rated fsb: 1600 mhz
ram: 400mhz 4-4-4-15-2t
working fine with 39c idle.
thins is voltage at cpu-z is 1.21 and uguru panel is like i set in the bios 1.35.
Temperatures showing diferentes as well in uguru and everest. :confused:
tomorrow im thinking to change the modules 6400 for one ocz 8500 sli(just pay the £35 dif cause my modules are 3 days old :D ). In ocz forum one guy say that works fine with abit quadgt, but i have little doubt since they ate sli. what do u think?

Ignore CPU-z for voltage readings, Ive noticed in other screenshots that its not reporting the vcore correctly.

Your core speed is 3.2 and your multiplier is x8. The default multiplier for e6600 is x9, and if u had the x9 set in the bios your cpu speed would be 3.6Ghz already. Its fine though as it is, nothing to worry about; but the option is there to set it to x9 if u want (will probably need more than default vcore to do it).

Your Ram speed at the moment is 400Mhz, this is equivalent to 800Mhz DDR (double data rate, date passed on the rising and falling edges of the digital signal trace). This is also called pc-6400.

You have had the RAM stable at 425Mhz = 850DDR this is already slightly overclocked from your memory's rated speed.

The next rated speed that they sell at is pc8000 which is 500Mhz = 1000DDR and pc 8500 is slightly higher still.

If you were recommended the memory on this forum, Im sure its a good set. Also since u have not had any problems with it yet and not hit an overclocking wall with it, I personally wouldnt change it. Sure its only £35 extra but that means u cant use your PC when u wait for new set?

Since u have a high cpu multiplier, RAM speed is not going to hold you back maxing the CPU speed.

Up 2 u, if u want to change it, but Id recommend trying to find the RAM's limits before u do. a lot of the time the cheaper RAM from a reputable manufacturer is as good as its top of the line RAM.
 
tks megatron!
makes me think again :confused:
but ive tried to increase the fsb and i think 3.6 is to much for my cooler. I just wondering that those pairs of OCZ 8500 could hit high frequency and lower timmings. its not better for £35???
 
So u have encountered instability when overclocking past what u had already? If so tell me the settings where u became unstable.

I think u should ask in the memory forum about which RAM is better. As it is I dont really know which set you have or are thinking about swapping for, perhaps tell me the full name and link plz? I dont know much about which memory is best which is why I said ask in the memory forums.

Apparently is the micron D9 chips which are good clockers:

afaik the OCZ 6400 Plats should be good for ~DDR2 900 so shouldn't be a problem until ~450 fsb (& 9x450= 4.05GHz which you probably aren't going to hit on air).

now is like this:
core speed: 3.2 ghz
multiplier: 8x
bus speed: 400mhz
So when u had 3.2Ghz it was stable for sure and u ran orthos? If so the cpu is good for 3.2Ghz at default voltage. Then u hit instability when the CPU was 2.8Ghz and memory was 410fsb. So its definately the memory and motherboard which is producing instability. However you might find that when u buy a new memory set that u will get instability at 410fsb again.

This would happen if its any of the motherboard voltages which needs to be tweaked, and this area is really well outside the limits of my knowledge :p . U have north bridge voltage, fsb voltage, mch voltage. I recommend a good guide or a set of know good settings. Since its a 965 board take a look at the Gigabyte DS3 thread for know good settings. I think u will find that the north bridge should be set at 1.4ish volts and have a little added cooling on it.


Think I found what u need:
