I overclocked my e8200 to 3.2 ghz with a max multiplier of 8 and a FBS of 400 Mhz
I'm new at this so please give me a hand
I searched the net and found out that 45nm processors have an recommended vcore voltage of 1.3625 so I set it like that.
I cant go more than 3.2 and there are alot of things I need info about
NB voltage - What is the recommended temperature ?
HT volt- What does it do ? How does it affect overclocking ?
CPU VTT voltage- (the same question)
SB voltage - (the same)
GTLVREF
NB BRO4 CHIP VOLT - (...)

Where did you hear that? I think you'r confusing VID with MAX voltage. The MAX voltage for 45nm Intel CPUs is 1.45v.

Keep NB temps below 55-60C. CPU VTT is the FSB voltage. If running high FSBs (FSB > 400) you'll probably need to raise this.
As for GTL: http://www.thetechrepository.com/showthread.php?t=87]

SB voltage is the South bridge voltage.

You probably can't get above 3.2Ghz because you'r OCing the RAM. If you have DDR2 800 RAM, you may not be able to go above FSB 400 since then you'll be OCing the RAM which doesn't like the OC. Make sure RAM voltage is correct.

Intel said that's the safest voltage. My ram can go to 1066 mhz so i don't think thats a problem but i don't know how to set the voltage on the rest of those things

OK. For the 45 nm CPU's, Intel's recommended maximum value is 1.3625 volts (happens to be the top of the VID range). Intel's recommended absolute value is 1.45 volts. I guess above that, long term damage starts happening. I'm not sure why they make that distinction.

This is all in Intel's tech data, but it's pretty dry reading.

monten, let's backup and look at some guides so you do not need to reinvent the wheel.

This should be your first stop.
HOWTO: Overclock C2Q (Quads) and C2D (Duals) - Guide v1.6.1
http://www.tomshardware.com/forum/240001-29-howto-overc...

Next stop should be a guide for your particular motherboard. Google is your friend.

You didn't post system specs, but if you have a Gigabyte motherboard, this is valuable:
Shadow's Gigabyte motherboard OC guide:
http://www.tomshardware.co.uk/forum/page-245679_11_0.ht...
It's for an EP35-DS3L but all the Gigabyte Core2 BIOS's are similar.

Go through the guides. Reset your BIOS to stock conditions.

Because your CPU has a relatively low internal multiplier, you have a little work to do with your RAM. Relax your RAM timing from 4-4-4-12 to 5's-15 or 5's-15 to 6's-18. Set your memory voltage to 2.2 volts. Change the System Memory Multiplier (or whatever your BIOS calls it) from AUTO to 2.00, 2.00B, or 2.00D - whichever you need to set the Memory Frequency to twice the FSB. Then when you increase the FSB, the memory clock will rise in in proportion with it. At an FSB of 333 MHz, your memory clock should be at 667 MHz.

Download CPU-Z to check your FSB:RAM ratio. It should be a 1:1 ratio.

Now you start the "increase FSB, test, monitor temps" cycle.

If you are going for a maximum overclock, you will need better than stock cooling. Here are three under $50 heatsinks that are pretty popular:
COOLER MASTER Hyper 212 Plus

Sunbeam
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Xigmatec Dark Knight
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Because they are all HDT type cooler, they all require a somewhat different approach to applying thermal compound. Suggestions for applying thermal compound:

And they are pretty large, so they might not fit inside your case.

A lot of this depends on how "overclocker friendly" your motherboard is. Many motherboards do not allow you to change some of these settings

Thanks for your answers!
Specs: Asus P5N-T Deluxe 780i SLI Motherboard
Intel e8200 with Prolimatech Megahalems rev. B heatsink and Scythe Slim Stream 1900rpm fan (33 idle. 40 full load)
RAM: Mushkin HP2-8500 2GB The RAM can go to 1066 mhz and currently its on 5-5-5-18
I have my CPU working at a fsb of 400 and a multiplier of 8 at 3.2ghz
Everything i tried i could not overclock more than 400 fsb, is the ram stopping me or something ?
With the ram set at a fsb of 400 (800mhz) i have a ratio of 1:1 and with a fsb of 533 (1066mhz) its at 4:3 i dont really understand how that works
What went wrong ?
March 28, 2010 12:09:17 PM

I tried a fsb of 420 on cpu and 840 on ram even with voltages of 1.45 vcore and 1.4 NB and the system didn't boot at all
I lowered the fsb to 410 vcore 1.36 and 1.3 NB 820fsb ram the system booted but it crashed after a few minutes of prime95.
Is my motherboard not capable of more than 400 fsb ?
March 28, 2010 11:06:11 PM

it may be problem with mobo that it is limiting above 1600fsb, but usually p45 chip does upto 1800 and even 2000. Dont know much about nvidia chips

Exactly!

@OP: Try relaxing the timing on the RAM and increase RAM voltage to ~2v.

It looks like you have the FSB:RAM on "Auto" change this to 1:1 manually. Also, it could be that there is an FSB hole at 420. Try 405, 425, and 415.

My Personal Contribution Is that his MOBO can't hit over 1600MHZ FSB... the Nvidia Chipsets aren't really OC friendly and my guess is that it will not go any further

Good luck :D

fisshy, I had an eVGA 680i motherboard that quit at a little over 440 MHz FSB freq. Not bad for 4 years ago. Down side was the MCP temp was around 85 C.

monten, when shadow recommended increase the RAM voltage, don't go above 2.2 volts.

The NForce board is holding that processor back in a P45 board that CPU can hit 4 ghz if done right. I used to have an E8200 in an ASUS p45 board and I ran everyday at 3.8ghz and was able to even go higher. 3.2ghz should not be giving you problems it is either you are overclocking the memory too high or the motherboard just can't do it.

Guys,

I have a mobo ASUS P5K-PRO with Intel p35 chipset and a CPU intel core 2 duo E8200 2,66GHZ.

Can i overclocking him at 3,2ghz increasing FSB from 333MHZ to 400MHZ ONLY????

or

I have to do anything else. MAYBE Other CPU cooler, OTHER VOLTAGE etc...

Thanks in advance

DIAS, I have a mobo ASUS P5QL-PRO and also have e8200 2,66 oc to 3,4GHz with fsb 425Mhz, 8x multiplier and still work good, in stress mode has 40'C, FSB:RAM 1:1, no voltage oc, CPU-Z show V 1,442V
btw, I forced to buy new pc case with fans. I bought Aerocool PGS Strike-X with 4-fans system and work great. Excelent to OC experiments.

Sorry for archeology but it can be usefull with OC...
Cheers
