Need help with overclocking :o)

[yiannis667]

Need help from those OVERCLOCKERS that know what they are doing :wavey: My system : Case Armor+ LCS Super Tower,Intel Core 2 Duo E8500 3.16Ghz Liquid Cooled,Kingston Value RaM 2 X 2 GB ddr2 800 mhz 5-5-5-18 with DOMINATOR AIR FLOW X 3 fans, Nvidia gt9600 1gb Overclocked,MOTHERBOARD GA-3G41MF-S2H F3 BIOS. I am trying to OVERCLOCK CPU but i cant go above 343 x 9.5 fsb (3.26 ghz) without having the system reboot and restore default settings.I am really new into this so my guess is that i have to manually change settings to achieve overclocking above these values...Which i dont know how to do,or where to start.My bios has 500 sub menus for memory timings,Cpu Voltages etc and messed around with them but no luck at all.With bios default values i can change cpu fsb from 333 x 9.5 3.16 ghz to 343 x 9.5 3.26 ghz and memory clock will automatically go to 823 mhz ? and everything will work fine.But thats as far that i can go.Can someone really give me detailed info on what to do , speaking numbers and really detailed info ? Why is my system restoring default values and wont boot if i raise cpu fsb above 343 x 9.5 ? I cant even go to 344 x 9.5 :nono: Plz help , will really appreciate any effort Thank you

I tried to google your board but didn't success so a few thing you shoud do is:

- Lower CPU multiplier to 6 and up FSB unstill your pc not stable (up NB voltage, FSB voltade will help your pc stable). E'rytime do that always check the RAM ratio, make sure it DOESN'T above 800Mhz (I think your RAM is not good for overclock)

- Record the highest FSB you can reach and change the CPU multipier to 9 and start again with CPU voltage up more like 1.3v should help CPU reach 3.6Ghz if your board can reach 400Mhz FSB.

Read more deatil here will help you more: http://forum.overclock3d.net/showthread.php?t=7110.

Another way if I were you, sell the mother board and memory, buy a good board and memory to over**** if you keen on. Good luck mate and welcome to OC3D anyway

i hear you buddy ! my case itself costs 4 times the value of that $#@$ of %$$@# motherboard Gigabyte mobos are kinda weird , i cant even put 8 gb of double sided memory in it it wont post ! i can oc memory by itself up to 915 mhz so far but no luck with cpu oc . which option is the nb voltage ? my bios shows these options for motherboard voltage control : cpu vcore , cpu termination , cpu reference , mch/ich core , dram voltage Thank you for your help so far , i really appreciate it

If you could take a photo of the screen with the voltage options, that would be really helpful.

i include pics of bios settings , with these settings it wont boot ( and with lower voltage settings ) thx

400FSB could well be too much of a push for your G41 motherboard.

You've done the right thing by setting your system memory multiplier to 2.0x. Now it's a matter of working out the optimal CPU frequency.

Start from the base 333FSB and increase in 10MHz increments, 340, 350, 360 and so on. Carefully observe the behaviour of your system every time you increase the FSB and run a stability test for a few minutes (say Prime95) to rat out serious instability. In the event of a BSOD or restart, try raising the MCH volts of your motherboard slightly. Ensure that integrated graphics is disabled too. As I say, I suspect your G41 based motherboard is the limiting factor here but let's see how it goes.

 

[Freak]

To see if its the mobo, use a low memory divider so that it underclocks. The same with your cpu. Then up the fsb till it will not post. I believe that being stressed wont do much for the fsb stabiliyt.

 

[Mul.]

He's already using a system memory multi of 2.0x. That's 1:1 in generic terms and as I understand, these intel chipset boards don't allow for dividers that run memory at a slower frequency to the base fsb clock.

 

[Ham]

Using the 400 strap (called MCH Latch) there will eliminate another option.

Also with 1.4v going through the NB make sure its not overheating. Toutch the HS and if its warm/burns you get a fan on it. Dont trust software/bios readings.

NB voltage in your case is "mch/ich core". You should start overclock again from scratch. Base on those pics you should lower CPU Clock Ratio to 6, Fine CPU Clock Ratio to Auto or 0, CPU vcore to Auto, keep everything else the same and check your pc boost or not. If its boost run prime95 or Orthos for 30' to check your pc stable or not. If its won't boost go back to BIOS and lower FSB to 395 and check again. Do it unstil your pc stable. We wil go to next step if you find out how far FSB you have got. Good luck mate

my pc boots with default bios settings and its stable.When trying to O.C above 343 x9.5 i got problems.Even with ddr2 downclocked as low as 680 mhz . I guess i cant find a way to sync memory to 1:1 above 343 x 9.5 cpu fsb.My bios shows Memory Mhz ( mch ? ) options 200 , 266 , 333 . If i choose 333 x 2.00 B or Mch AUTO with multiplier at 2.00 B my memory will show 800 mhz frequency at 400 x 9.5 , Even lower frequency at lower cpu fsb.But when i go above 343 x 9.5 NOTHING BOOTS . ( ex 344 x 9.5 ! ) . If i stay at 343 x 9.5 cpu fsb i can overclock memory to 913 mhz ( so far it works at that speed highest ) or even downclock memory with no problem as low as 680 mhz . So i really dont know what's keeping it from doing the same above 343 x 9.5 cpu fsb . I raised all voltages and yada yada yada but had no luck so far . I guess by the time i enter MAX 400 x 9.5 cpu fsb with memory MCH to 333 x 2.00 B or AUTO X 2.00 B memory multiplier ( even tried much lower cpu fsb , it wont boot above 343 x 9.5 MAX SAFE BOOT OR BOOT AT ALL ) and gives me 800 mhz frequency thats 1:1 correct ? I raised memory voltages up to 2.1 voltss, NB up to 1,4 , CPU up to 1,35 volts but nothings boots.I can play all i want as far that i dont go above 343 x 9.5 = 3.26 ghz which SUCKS . I dont know why any ideas ? I can even overclock memory to 913 mhz as long that i dont go above 343 x 9.5 :nono: Plz help I am about to BURN this computer WITH GASOLINE AND MATCHES !!! Whats keeping me from doing it so far is my Armor + LCS case :worship: HELP ! :worship: If i ever get the EVGA x58 Classified (someday) will it give me the same hard time this Gigabyte #$%@$@ is giving me ?

right 1:1 would be 400fsb - 800mem, and the rest is probably your mobo matey tbh,

But burn your case too, Better off with proper air cooling than the Tt waste of copper you have.

Dont think so , 5 Aerocool 140 MM fans , 1 Thermaltake 120 MM Programmable Led Fan also installed in my case and having that COPPER makes my cpu run at 17 to 21 celcius at full load . I bet your cpu FAN dont do that :nono:

17c to 21c fully loaded simply isn't possible on an E8400 unless you've got a top end watercooling loop along with a fairly hefty peltier setup. That or ambient temperatures of 0c to 5c...

My guess is that your temperature sensors are faulty or the program that you're reading them with have detected the incorrect TJunction. Alternatively, you're reading the CPU "Socket" temperatures or the readings from a separate temperature probe connected to a display on your case, both of which are inaccurate.

Oh i am sorry , I forgot to mention the 230 MM fan my case has on the side window.Not to mention that my CPU is E8500 and not E8400 and my CPU TEMPERATURES ARE FROM 17 TO 21 CELCIUS IN FULL LOAD . NOT MORE NOT LESS

 

[Mul.]

It's debatable but at best, the action of a fan system drawing cool air in and exhausting warm air out can only cool the innards of the case to the ambient temperature outside the case. If the ambient temperature in your room is what standard room temperature is meant to be, I'm at a loss to understand how your watercooling setup can cool a 65W TDP CPU to roughly the same temperature as what a room should be?

What are you using to determine your CPU temperature?

Please don't misunderstand my post as though I think you're telling fibs as I'm merely helping you find out the actual temperature of your CPU.

Besides my AquaBay Sensor Temps , Bios Temps , And ET 6 Temps the readings I gave you came from SpeedFan , Hmonitor . Cant go wrong with them . Well anyways i have a nice case at least and i bet many people agree to that . Its Nvidia Sli Certified tho and not much popular for AMD fans

 

[Mul.]

For the record, I'm not a fan of any manufacturer

"Aquabay", BIOS and Easytune all read from the CPU socket. The temperature detected from the socket is not the true temperature. The one you're after is the Internal DTS inside the CPU. This can be read with Coretemp, Everest and HWMonitor.

Come on now TT Armor+ LCS is a nice case .... It's like having a Lian Li ATI Edition case for Amd Cpu's isnt ? I used to have coretemp , here is what i am going to do , i will run it take a picture and upload it here as long as you agree that i have a nice case ! :wavey:

 

[yiannis667]

And you are right i am giving you the socket temp , not the core temp . But with air cooling your e8500 will be at 28 to 38 celsius stand by ? socket temp without any ocing done.Thats a big difference ....
