Does anyone out there have a GA-965P DS3 board with the core 2 duo E6400 clocked at least 3GHz with 2gb of ddr2 corsair and stock heatsink that is stable. I would love to get the specs.
Thanks

The E6400 is pretty good for overclocking. Many, including myself, run the 6400 @ 3.2 with no problems.

(1) what memory do you have as this can inpact your OC. DDR2-667 mmory would have to be OCed to go above 2.67 GHz. (Bus = 333 MHz x 8 = 2.667 GHz and Memory @ 1 to 1 Ratio). If you have DDR2-800 you would be good upto 3.2 GHZ. Also make sure your DIMM voltage is set to manf spec.

(2) What is your current idle temps and Max load temps. For this Intels TAT program is pretty good as it will display core temps and you can set the CPU load and monitor temps. Prime 95 will also load CPU and test stability. The stock cooler is very poor, many including myself recommend using it as a paper weight even at stock. If your loaded temps are close to 60 or above, you WILL need a better HSF. The cooler you keep your proc the longer it is going to last.

(3) Read sticky at top on overclocking procedure and follow OC forum - will indicate what parameters to disable like speed step.

I have the 965-DQ6 (similar to yours) and the only think I needed to do was set the Bus to 400 and memory to 2.0 (1::1) and then I set the memory Dimm Voltage to Manf specs (+.3 for my corsair's to get 2.1 V). I left all other voltages on auto (When I increased memory to 4 gigs I had to increase FSB and GMCH voltage by 0.1V)

Thanks for the reply

I just added 2 more gb of corsair ddr2 to my computer. My first 2gb runs on corsair also but it says 667 and the two I just bought says 800. I'm not sure what to do there. I'm not understanding the gmch voltage increase. Where should I have it now.
When I only had 2gb of mem, Core temp read at 55c idle with 0% load and around 60c at 70% load at core speed of 2.8, bus speed at 350mhz, core voltage at 1.344v.
Now that I added the extra 2gb making it 4gb. My core tem is running idle at 45c with 0% load. Should I change anything in my bios because I just added 2gb of ram.
I've used orthos but nothing ever lasted. It usually gives me an error soon within a few seconds or a few minutes. Because of that, I've been trying to over clock my computer for about ten plus hrs now. So I really need some help.
Thanks

(1) generally it is not recommended to mix your memory speed. If you do you normally will run at the slower speed.

(2) I would try your over clock with just the two sticks of the DDR2-800). Did you set the DDR2 Dimm voltage to the recommended settings. Down load CPUZ and run it. Look at the the SPD tab and set your voltages (DIMM V) and timmings to the correct values. For the gigabyte MB it sets the Dimm voltage to 1.8 V so if you need 2.0 you would set it to +0.2 V
http://www.cpuid.com/cpuz.php

(3) Did you bump your CPU voltage up, or did the "Auto" bump it up. My E6400 is running at 1.216 V (@3.2 GHz.)

(4) Prime 95 errors are normally do to memory not set correct.

(5) try to Keep your CPU voltage as low as possible and do not exceed 65C - AS I SAID The stock cooler is crap!

(6) for all for memory sticks, I would limit my OC to Bus = 333 (Matches your DDR2-667 and run your DDR-800 @ 667

I took your advise and brought it down to 333
So now what i got going is:
CoreTemp:
Core #0 at 56c Low: 47c High: 58c Load: 100%
Have my orthos running for more than ten minutes now and still going.
CPU-Z:
Core Voltage: 1.312v set in bios at 1.32500v
Core Speed: 2664.1mhz in bios at 333
Muliplier at 8
Rated FSB: 1332.0 Mhz
my memory clocked at 4-4-4-12, 1:1 running all four sticks of corsair ddr2
(2x at 675) and (2x at 800). Will probably replace the 2x 675 or should i upgrade it all to four ddr2 1066?
In my bios, I have my
PCI Express frequency at 100
Memory Performance Enhance at normal
DDR2 overvoltage control at +.2v
PCI-E overvoltage control at normal
FSB overvoltage control at +.2v
GMCH overvoltage control at normal
CPU voltage control at 1.32500v
I don't know if I have the settings correctly or not.
I also have the ATI radeon x1900gt, if that makes any difference. What do you think? Should I change anything? I would love to bring it up to a 2.8 or 3Ghz.
What do you think I should do to achieve that? If you need more information that I left out, please let me know.
Thanks

(1) Your temps (Idle = 47) ARE High. 58 C is about as high as you want to get. I get 57 C at 3.2 GHz BUT my CPU voltage is only 1.22 Volts. The link below is from an Old poster back when the C2Ds and Quad came out. Alot of people were having problems with the stock HSF.
http://www.supremelaw.org/systems/heatsinks/warning.htm
First get a good HSF - Recommend one with a backing plate - Does NOT have to be Expensive one, Approx $30 ( I have the Zalman 9500)

(2) NO to DDR2-1066. DDR2-1066 is just overclocked DDR2-800. DDR2-800 at 1 to 1 will support 3.2 GHz. However with the cost of memory I would recommend replacing with 2 sticks of 2 Gig DDR2-800. Corsair is very good, never had a problem with. I went with two sticks of Mushkins and am very pleased. Two sticks is easier to abtain stable operation with than 4 sticks of ram.

(3) I would try lowering your FSB voltage to +0.1 and increase your GMCH to +0.1. If you can get your memory stable, I would try to lower the Vcore voltage. Memory stability is harder with 4 sticks and Mismatch memory does not help.

Info from Hareware Monitor E6400 @ 3.2 Room temp approx 75 F
Voltage CPU VCORE 1.22 Volts
Voltage DDR 2.05 Volts
Temperature System 42°C (107°F
Temperature CPU 29°C (84°F)
Core #0 35°C (94°F) 90% load w/TAT = 57 C
Core #1 36°C (96°F) 90% load w/TAT = 58 C

Added: Example: for A HSF for $25.00 (Had pretty good reviews - there are better ones FOR considerably more bucks, but for the price , HARD to BEAT)

Thank you so much for your time and help. I will looke into the fan and remove the 2 sticks of the 675 and leave 800. When I have the money to replace those with just the 2 sticks of 2gb each, I'll let you know. Thanks again. I'll keep in touch with you. :bounce:

So I went out to fry's and got the Zalman 9500A and just installed it. Is the RPM supposed to be around 680 during idle? I took out the both ddr2 675 and left in the two ddr2 800. Still running at 2.66ghz at 1.32v
Core temp reads at 40c at idle and 51c at 100% load. Pretty much all the same setting. I adjust the knob both ways and just a little turn puts the rpm at 0 so I have to leave it on full. There's no led light either. Do you think I might have a defective product?

(1) in your bios there should be a selection (PC Health Status). Do not use PWM or auto, I use disable which provides the full voltage and your fan control should work. The LED is not comming on because it is not getting enough voltage. If that does not work, then the fan is defective.

(2) The idle temp will drop as fan speed as RPMs will be your seting I just back it off from the High. The 51 @ load is much better than your previous 58 C. My idle (w/same cooler) is 35 -> 37 C. You must also factor in your room temp. Right now my room temp is approx 72 F.

Wow, that helped out a lot. The fan is working correctly now. Thanks so much. oh yeah, my room temp is currently at 67. I live in seattle and it's getting pretty cold. :D 
It's idle'n at 33c and I'm running orthos and it's reach high of 44c with 100% load. It also dropped my gpu core down to a 55c which was before around 61c. I'm gonna play around with the overclocking to see if I can get it stable at 3.0ghz with just the two sticks of ddr2 800. What do you think that I can probably get it up to and what the core voltage should be.
I'm not really sure what to do with the DDR2 overvoltage control. I have that set at +.2. PCI-E overvoltage at normal. FSB overvoltage at +.2, GMCH at normal, currently my cpu voltage is at 1.300v. There's also this Normal CPU voltage in blue that says 1.325v. What does that mean. Can I go below that or is that the lowest setting I can have for my system?
How long should I run orthos to know that everything is stable? I mostly just do a lot of downloading and surf the net, watch movies on my computer and maybe game here and there. I first built this comp to play games but I haven't done that for a while. might get back into it. I do a lot of shooting games and normally play for 6hrs plus if I get started again. Thanks

Currently @ work.
Temps Look great

(1) Raise Dimm Voltage from +0.2 to +0.3. Your screen shot shows you have 1.99 and Your Ram is for 2.1V
(2) Set (G)MCH and FSB voltages to +0.1 V
(3) Verify stability

If Stable try lowering your CPU voltage slowly down to 1.22 (Use hardwarmonitor to verify. If you can get it down to 1.2 then change to auto.

I currently have my core speed at 2880 mhz and core voltage at 1.360v. After running orthos for 6 hrs, it finally gave me the warning. Should I keep raising the cpu vcore?
Is it safe to max out on the fan and leave it there? I currently have it at min running around 1450 rpm. What do you have yours set at?
With these setting, my idle temp is at 40c and reaches about 54c at full load. Room temp at 77f. Dimm V at +.3, Gmch and FSB voltage both at +.1

(1) While testing, I would set CPU fan to approx 3/4 -> 90% of max. When all is said and done I would set fan so that Max Core 0 & 1 do not exceed 60 C. NOTE base temps on core temps.

(2) When you look at your Ram Voltage using Hardware monitor, does it show 2.1 V.

(3) I would loosen the ram timing to 5-5-5-5-18 untill you complete Overclocking.
Is your error in orthos CPU, or memory fail error?

(4) Then try lowering your cpu voltage. Just test with ortho for 1 hour, lower again to see what voltage level you can get to.


(4) I would not like to go any higher on your CPU Voltage. As I indicate I am at 3.2 with Voltage on auto (1.216 V) and I've seen several post of others reaching 3.2 at stock.

If every thing looks good you can shoot for bus = 400

Added: Keep the loose memory timings (5-5-5-5-18)When you are ready to try bus 2 400, Set your CPU multiplier to 6 (2.4 GHz), Check, if ok then raise Multiplier to 7 (2.8 GHz) test, then shoot for the moon with multiplier set to 8 (3.2 GHz). If all is good then try improving memory timings.

Looking at my ram voltage using the hardware monitor, it says 2.0v. I have it set in bios at +.2. Should I up it to +.3?
Your computer reaching 3.2 at 1.216? Do we have the same stuff? As in hardware wise I mean. Same ram mem amount? I'm going to try those settings and I'll let you know. How do you know if it's cpu or mem error in orthos?

I tried to put the mem ram at the 5-5-5-18 setting and it didn't do so good. Sometimes it would not even start up windows. I'm back at 4-4-4-12. I guess 2.8ghz is good enough for me for now. I'm currently running orthos with core voltage at 1.344v to see how that goes. I'm not sure how you got your core voltage so low. I tried to set it down to the normal 1.325 and ran orthos and it gave me an error within a few seconds. Could it be that my power supply is only 420watt? I'm also running ATI x1900gt that requires 450watt supply, could that be an issue also? So I have my Bus speed at 350, will probably try 2.88ghz later if everything looks good.
How do you know when your computer is stable?

(1) yes up Ram voltage to =0.3. Your Ram SPD shows it should be 2.1 V

(2) look at my "More info" for Hardwar that I have.

(3) Yes it could be your PSU. That Hardwaremonitor snapshot, the voltages looked good for min max for every think EXCEPT +12 V (Min looks fishy) The +12V supplies voltage to tyour CPU inaddition to the GPU. If it is dropping below 11.4 V when under load, Then you need a better PSU!!!! A GOOD 450 should handle your load, myself I would go with a GOOD 500 to 550 PSU.

(4) My CPU voltage is at stock, I never touched it. For my OC I only had to set the Ram Voltage to Manuf specs and raised the FSB and GMCH voltage by =0.1 V. orginally I had the same memory as you did ( 4 x 1 Gig Corsair DDR2-800 (PC6400).

(5) I ran orthoes for about 3 -> 4 hours and for the Past 2 Yrs I never had a problem.

My core temp went high of 45c with a 95% load while playing Lord of the ring. My CPUID Hardware shows +12v value: 12.29 Min: 11.90v, Max: 12.35v after I exited the game. Should that be ok. The min did get kinda low.

Your +12 V: Min Max are fine and do not indicate a problem. Specs are +/- 5 % which means good from 11. 4 to 12.6 (Myself Min for the +12 should be no lower than 11.6). I normally verify with a voltmeter. Then I know if the software is reporting correct. Another problem with software generated values is in the timing and it does not always catch a spike (either low, or high). Have you checked the rating (a review) of your PSU. You did not specify PSU make.

The reason I asked about the +12 is that your screen shot show +1.94 Volts (Should be invaid as computer would not work at that level - Unless it was a very-very short spike (a few microsec).
The 45 C for core temp, is that for both cores, if so temps are GREAT.
