i am new to overclocking i have to overclock my C2D e7500. gigabyte ga-g41m rev. 2.0 combo motherboard please tell me the settings to set in mobo bios and what the max FSB i can set??
OK, sorry it took a while to get back to you. The stock Intel cooler is fine even for overclocking. I can only assume the difference between yours & Fingers temps is that he applied the thermal paste correctly & you did not.
Here's your overclock settings for 3.33GHz:
CPU Clock Ratio = 10x
Fine CPU Clock Ratio = +0.0CPU Host Clock Control = Enabled
CPU Host Clock Frequency = 333MHz
PCI Express Frequency = 100MHz(G)MCH Frequency Latch = 333MHz
System Memory Multiplier = 2.00BThe Latch & Multiplier always throw me off so hopefully I chose the right settings. If I'm correct, the CPU will run at 3.33GHz at 1333MHz FSB & the RAM will run at 667MHz DDR.
You cannot overclock the onboard graphics. If you're into gaming, buy a gaming video card, there's no way around it.
We need to know the type (DDR2 or DDR3) & speed of your RAM. The C2D performs best when the CPU:RAM frequencies are kept at a 1:1 or 1:2 ratio. The E7500 has a default FSB speed of 1066MHz which is 266MHz frequency, so the ideal RAM frequency when not overclocking is either 266MHz or 533MHz. When the CPU frequency is increased, the RAM frequency should stay in step. Are you using the stock CPU cooler or an aftermarket one? Are you running a graphics card or onboard graphics? What's the make/model/wattage of your power supply?
Here's your board specs: http://www.gigabyte.com/products/pr...
Here's the manual: http://download.gigabyte.us/FileLis...
A simple increase of the FSB from 1066MHz to 1333MHz would overclock the CPU to 3.67GHz, but that may be too much. If the CPU multipler is dropped from 11 to 10, the CPU speed would be 3.33GHz but there are a LOT of other settings that should be addressed as well.
Start by providing the RAM info.
thanks i have Tamkor 2*2GB DDR3 @ 800Mhz . in cpu-z it shows 667Mhz and in task manager it shows 800Mhz.
Currently i am using stock cooler but i planned to buy hyper TX3 EVO this month.
i am using inbuilt graphics of g41 chipset X4500 with 1759Mb.
my power suppy is of UMAX 450Watts.
can i also overclock inbuilt graphics little??????
sir this is my full specification of my pc in that video
Nice job with the screencast. I'll get back to you with some o/c settings later. "thanks i have Tamkor 2*2GB DDR3 @ 800Mhz . in cpu-z it shows 667Mhz and in task manager it shows 800Mhz"
No, you have DDR3-1066 & it's running at 533MHz @ 1:2 ratio. Exactly how it should be setup when not overclocked.
"i am using stock cooler but i planned to buy hyper TX3 EVO this month"
Save your money. There's no need for an aftermarket cooler.
"i am using inbuilt graphics of g41 chipset X4500"
Apparently you're not a gamer? And if you are, I suggest you use the money you were going to spend on the cooler & invest in a gaming video card.
"my power suppy is of UMAX 450Watts"
Unfortunately, it's low end garbage. Are you from India? Forget what I said about the video card, you need a decent power supply before you can upgrade the graphics.
sir i want to buy aftermarket cooler because at full load temperature reaches above 85C which is greater than processor limit.whether i should by hyper tx3 or not?
i am not a gamer just do like everyday gaming.please tell me whether i can boost its performance or not?
yes sir i am from india and 15 year's old.
there is MIT intelligent tweaker in bios please tell the settings of that overclocking.
thanks sir................................................................
If you're 100% sure that temp reading is accurate, your stock cooler was probably installed incorrectly. Using the right amount of thermal paste & laying it across the CPU in the right direction is critical to proper cooling. Here's the method for the C2D: http://s17.beta.photobucket.com/use...
Here's why: http://img22.imageshack.us/img22/41...
Listen to riider, I have an E7500 that is nicely OC'd on a G41 board running a stock heat sink and idle is in the mid 30's C and has never gone over 55C or so. I will not post my OC since I would rather let the recommendations come from a single source as to be less confusing (besides, for some reason, I cannot see your video specs but apparently riider can). Unless you already have too much voltage going to the CPU, all you need to do is clean off all of the thermal material on the CPU and heat sink and reapply compound correctly and you will see a major improvement in your temps. You have to be a little bit crazy to keep you from going insane.
sir can you send me the photo of your stock fan my stockfan run at max 2829RPM and i have push pin bracket stock fan of intel

The stock graphics on your board are pretty basic and overclocking is easier to achieve stability with separate graphics card since it takes the stress off the chipset.
Yes, it is a stock heat sink, black plastic body, aluminum heatsink/fins with the white plastic push pins. These pins must appear uniform from the underside of the motherboard with the white plastic tabs being held apart with the metal pins between them. Remove the heat sink, clean both surfaces with a high quality rubbing alcohol, and apply the proper amount of new thermal compound.

sir i ahave applied all settings but there is no multiplier as 2.00B
sir now core voltage is 1.36 is it safe or not???
Sort of. It is within range, but probably much higher than you really need. Go with the lowest that will give you stability. More voltage will only generate more heat and shorten overall life. Try your VCore (CPU Voltage) closer to 1.850 or 1.200 (on my E8200 machine, CPUz shows 1.185V one moment and 1.200Volts the next, my E7500 machine is being used by someone else right now)
0.85V - 1.3625VYou have to be a little bit crazy to keep you from going insane.
What are your temperatures in Speedfan or HWMonitor? Your temps and your stability are both important parts of overclocking. You have to be a little bit crazy to keep you from going insane.
"i ahave applied all settings but there is no multiplier as 2.00B" Nothing to worry about, everything looks good. CPU is at 3.33GHz @ 1333MHz FSB & the RAM is running at 667MHz. Good job. The CPU voltage range is 0.8500V-V1.3625 but that will vary due to SpeedStep.

You can try stability testing by running Prime95. If you get any errors or problems, you'll have to tweak the settings a bit:
when run prime95 for 5 minutes temp rises above 70C. can i set fsb of 1100,1200etc
"when run prime95 for 5 minutes temp rises above 70C" Of course it's going to heat up, that's the idea. You're stress testing to check for stability. The CPU will NOT overheat to death, it has built in thermal protection.
You were told that the CPU cooler is most likely installed incorrectly. Have you removed it, cleaned off all the old thermal material, applied fresh thermal paste, then reinstalled it? If not, that should be your next move.
When you consider temperatures after an overclock, you look at the temperatures at:
Idle
Normal Use (internet, email, word, excel, etc.)
Aggressive use, like gaming
and Stress testing
A normal temperature range MAY be 30's C Idle, 40's C Normal Use, 50's C Gaming, and 60's or even low 70's during stress testing. These are fine IF you are close to that range, or possibly even a little bit higher. You are looking for the lowest reasonable temperatures you can achieve, so reset your heat sink and experiment with slightly lower VCore voltages. Use the lowest voltage that will still be 100% stable during testing. If you lower it a few times and suddenly it becomes unstable, just raise it a notch or two and test it again. Overclocking a system for normal use takes a little bit of experimenting to get everything just right, but with the numbers you have, it should not be too difficult.

yes sir i removed old paste and applied new one and previosly heatsink was installed incorrectly,now without overclocking idle temp is 33C and at max load 60C. but now when i overclock previously vcore is 1.36V but now it is 1.39V. therefore i doesnt overclock right now please tell if i can set FSB to the value i like eg:-1100Mhz , 1200Mhz etc.
Your voltage is too high, overvolting can damage your CPU. You absolutely have to get a handle on your voltage, your acceptable voltage range is 0.85V - 1.3625V and the base or stock default voltage should be around 1.125V if I remember correctly. You need to either reset your BIOS defaults and see if your base voltage comes down, or you are going to have to set it manually. You should shoot for between 1.1V and 1.25V if possible, but do not go over the maximum range and lower is much better as far as your temperatures and CPU life. You have to be a little bit crazy to keep you from going insane.
now i limited voltages to 1.3 and currently it is showing core voltage 1.280. sir is limiting voltage from bios affect my computer performance
The C2D generally doesn't need a voltage boost unless a "major" overclock is done. Going from 2.93GHz to 3.33GHz is only 14%, that isn't all that much. The main advantage is the FSB increase from 1066MHz to 1333MHz which is a 25% increase. There should be no need to touch the CPU voltage setting, leave it on AUTO. If you find the voltage is changing, it's because SpeedStep (EIST) is doing it's job. http://www.techopedia.com/definitio...
If you were to change the settings to 8 x 400MHz (1600MHz FSB), the CPU clock speed would be lower (3.2GHz, only a 9% overclock) but it would perform better because the FSB would be increased 50% over stock. Not only that, but the RAM would be running as DDR800 rather than DDR667.
riider: as far as I know, the G41 motherboards chipset supports up to FSB1333 unless you have experience clocking them above that. I only went a little over Freq. 333 on that board once (I may have tried somewhere up to Freq. 350) and it did not react well so I did not push it. It runs well at 333 x 11 so I left it. You have to be a little bit crazy to keep you from going insane.
sir but when i set voltages to auto its idle vcore becomes 1.38-1.39V which is above its limit.
"the G41 motherboards chipset supports up to FSB1333 unless you have experience clocking them above that" Actually, I never worked with the G41 but I figured it overclocked similar to the P45. Did you try increasing the northbridge voltage at all?
"when i set voltages to auto its idle vcore becomes 1.38-1.39V which is above its limit"
Don't worry about it. According to Intel, 1.45v is the "absolute max" but some have run it even higher than that without issue. See page 17, table 3:
Hmmm... Never seen CPWorld wrong on voltages before.
When I had an E8200 on that G41 board I tried OC'ing over FSB1333 and went up some, but even with a small chipset volt increase, I did not get too far. That is when I decided to get the E7500 for that board and save the E8200 for the next build which would be a P43 or P45 board. It turned out that everyone appeared to be out of the P45's at the time (new) so I went with the P43. The OC on the E8200 is reasonable at 3.2GHz (400x8) and I have been just plain lazy about going further (the voltages and temps are very reasonable, I just have to find the motivation) with both machines. One day when I retire one or both of these, I will put the E7500 into the P43 machine and see how much I can push it. Eventually, and Ivy Bridge or Haswell though....If the machine is stable and the temps are reasonable, riider is most likely right and you are fine. Get your overclock and stability first, you can always try bumping down the voltage later and retesting for stability to see how cool you can get it to run. If you loose stability, just go back up a little.

sir i am asking that there is any disadvantage of limiting voltage from bios because when i set it to auto ,idle it was 1.39 and on load it goes up and up
If you limit the voltage then you potentially are reducing heat build up within the CPU and under more extreme conditions, extend the usable life of the CPU. The downside is that it will take some experimenting to get the voltage right and when it is set too low, you will crash at higher stress, which is why you absolutely need to stress test it at each voltage that you try. If you find a voltage that works normally, but freezes or crashes during stress testing, you bring it up a notch at a time and retest until it is completely stable. The stress test is beyond anything you would normally do so you should be nearly 100% good at that point (if you can then run it 24/7 for a couple of months during normal use, you ARE 100% at that point). You have to be a little bit crazy to keep you from going insane.
sir i now i have limited voltages to 1.28750V now all is working fine at idle voltage is 1.088V ans at max load 1.266V and speedstep is changing voltages per second which is good.
Sounds good.
Just for clarity, post your OC specs and your temperature range mainly since this may help someone else in the future.You have to be a little bit crazy to keep you from going insane.
CPU Clock Ratio = 10x
