Starting my Overclock on my CPU .. how r these voltages so far

overclocking my Q6600 kentfield 2.4ghz


right now im at 3.42ghz FSB 380 x 9 multiplier

voltage is ~ 1.402


How is this.. im planning on going higher to about 3.6ghz

I have DDR2 800 ram
while setting my overclock i set my system memory multiplier to match as close as i can to 800 but got around 760 is that alright?

As long as temps are OK voltage doesn't matter much.

As for your ram, well do you have on option in your bios to ''Unlink'' and manually set the ram's speed? What timings are you running, and what voltage? Typically most 800 ram can be overclocked decently.

my temps run from 32 degrees C on core 1 to 17 degrees C on core 4 at idle.. at full load they run to about 50 degrees C.

now for the ram. I dont think i can "Unlink" there isnt a option for it. and my timings are set to auto. there stock timings are 5 5 5 15. should i turn auto off and set the stock timings in there? Voltage is also set to normal on the ram. Have not changed it.

When running Prime95 i keep on getting a error on core 3 ( FATAL ERROR: Rounding was 0.5, expected less than 0.4 ) what does that mean and how do i fix that? is that a voltage or a ram issue?
 
What voltage is your ram and Northbridge at?

what brand is your ram?....might need to adjust those timings too.

Im not a pro when it comes to overclocking,so please bare with me,I have done a nice OC with my Q6600 though and its been great ;)

You have your computer in a refrigerator? 17c is only 62F. 50C is plenty cool at full load, not need to worry there. I believe max spec is around 70C.

Yeah I never use auto, it switches around the ram timings when you mess with other stuff sometimes. Whats the normal voltage?

Not sure on the error, never had that one. Maybe someone else can chime in there. Or just do a google search, I'm sure others have had the problem.

The voltage of my ram and northbridge r both set to normal. i have not touched either one of them. i cant see the exact voltage on both of them in BIOs.. it just says normal.

my ram is G.SKILL 8GB DDR2 SDRAM DDR2 800 (6400) Dual Channel 2gb x 4 sticks.. stock timings r 5 5 5 15
 
There's 3 different G.Skill ram's with ddr2-800 and 5-5-5-15 timings. What color heatsinks? Dark blue? Grey? Or no heat sinks? They all use different voltages, which is why I'm asking.
 
OK those ones will probably be at 1.9v as the ''normal''. All you need to do in the Bios is select +.1v and right beside it then it will tell you what voltage it will be at with +.1v. I'm betting if you select +.1 it will be 2.0v. Anything below 2.2 is relatively safe for ddr2, if thats what it takes to get your ram stable.

So right now it looks like your FSB/ram ratio 1:2. Whats the next higher setting?

alright i thought i would post a few pics of my BIO's so u would see exactly what my settings r at. I did add the voltage like u said but as soon as windows started loading the computer crashed so i set it back to normal

if u see anything that needs changing let me know.. i dont understand if i added +.1 to my voltage why would i instantly crash.. the option wasnt even flashing read like the .5
 
Hmm yeah I don't like gigabyte's bios layout. I've had ASrock, biostar, and DFI boards, all of them had a better Bios layout than gigabyte.
In mine, when I select +.1v, it atleast gives the total voltage there beside the setting. Yours doesn't seem to do that. And yeah no clue why it would crash with just a nominal voltage increase over stock voltage like that. Weird!

What is the next highest memory multiplier?
 
Well, thats 950. Have you tried to just set it to 2.5 and boot? Leave stock voltage I guess since more makes it crash, but 5-5-5-15 is semi-loose timings for ddr2-800 so it may work. Or it may not, you may need to clear the Cmos.
 
Or, what you could try to do is leave it at 760 and see if you can run 4-4-4-12 timing.

ill try both ... first ill try setting the multiplier to 2.50 and restart.. if i crash ill set it back and change the timings.. i just dont wanna lose performance on my ram is all.. will 4 4 4 12 hurt performance..

also if u know anything bout video cards.. i overclocked that also. i have a EVGA 8800gt stock is 600mhz clock 1500mhz shader and 900 (1800) memory... i boosted it up to 720/1785/1000 (2000) and it got through 3dmark06 no fails.... and temp reach 66 degrees celcius.. is that decent?

i did crash at 735/1800/1000 so i tuned it down a bit and now it works fine
 
hummm i was wrong the next muliplier was 2.40 so 912 .... i booted with that and crashed.. but i went back in bios and added +0.2V in the ram and i booted just fine.. timings r still 5-5-5-15

4-4-4-12 timing is faster! The lower the number, the better.

OK I'd leave the core clock at 720, and try to increase the memory clock more. The stock clocks on my 250gts are 756/1100...max I can run stable is 825/1350. You can get a lot more memory speed, which is where you are going to see good increases on 3dmark06.
Are you using EVGA precision tool?

Thats excellent. You should definitely get 1-2 FPS increase in some games with that memory speed increase. Thats probably about maxxed out there, lets move on to your 8800gt. I'm guessing you'll get around 1200 mhz (2400) stable with that card, if it overclocks as good as my gts250. That much increase will probably mean 4-5 FPS and probably about 500 3dmarks better score. Whats your score now? Somewhere around 10-12K?

Bleh with my multiplier settings at 2.40 and the voltage at +.2v prime95 got a error on core 3 within 5 seconds... so obvisouly this is wrong.. shall i go back to 2.00 and then bring the voltage back to normal and bring the timings to 4-4-4-12? when i do that i will need to increase voltage?

and yes i am using EVGA precision. So i should leave the shader and core clock and raise the memory clock.. how high u think i should go?
