I took my first venture into overclocking!

I increased the CPU Host Frequency from 333 to 338, not a big step I know and I'm now at 338 x 9.5 = 3211Mhz, I changed the right thing didn't I? CPU-Z says the bus speed is now 338.00 Mhz, so I assumed thats the right thing.
Can someone tell me what the exact option in the BIOS is to turn on speedstep cause my CPU Fan is annoying me. So to reiterate, did I change the right thing, and what is the option in the BIOS is for speedstep. :D
 
yeah you changed the right thing! keep uping the fsb 10mhz at a time and see who high it will go. are you using a stock hsf?

I might be wrong but speedstep does not affect your cpu fan. let us know your specs and we might be able to help more.
 
stock hsf = stock cooling? sorry I'm not up on this, I'm not using a stock cooler anyway,

E8500 w/ Akasa AK-961 CPU Cooler on a Gigabyte EP45-DS3R, If I remember speedstep would only let the CPU go as fast as it needs to, cause right now its constantly at 3200Mhz even at idle.
 
i've not used a gigabyte board so cant help with the speedstep. your right it changes the multi (the *9.5 bit) up and down as it needs to.

in an E8500 you should be about to go a lot higher that you are. my E8400 is at 3.8
 
haha, it get a bit more complex than that the more you get into it but yeah just uping the fsb is the way to start.

dont leave your cpu volts an auto though it may over volt it.

you'll need to test it to make sure its stable though. use prime95 torture test and let it run for a few hours to see if all is ok.

you should be able to get to 3.7/8 easy with just fsb increases.

Heh I bet you think you sound like a proper geek huh! :p

You increased the CPU Host Frequency heh! :o

You gotta get the lingo right if your gonna be a geek proper, otherwise you will stick out like a freshman and get mercilessly taunted by the Hitmen!

Translations proper would be:

"I cranked the FSB Baby!

"I raised the System Bus"

"I have no nuggets so I dare not pump the FSB more than 1.5%"

Obviously a large sense of humour would help, good work with your first overclock and I shall watch this space to see how you fare! ;)

made me smile :)

In response to the OP

Set you CPU back to its default clock, boot into windows and load up core temp, take a look at the VID, go back into the BIOS and set your CPU vcore to the VID, this is like the "default" voltage. Start raising your FSB slowly in 10 - 20 mhz jumps, each time boot to windows and run prime95 for 15 mins... do this until it fails (make sure in the advanced menu you click error detection)... then back into the bios and boost your vcore by 0.05v i.e. if you are at 1.2v change it to 1.25v, at all times keep an eye on your CPU temps, use realtemp or coretemp to measure these make sure they stay below 70/75c... under prime small ffts load

its also advisable to take your RAM out of the question when it comes to stability, I would set it to 1 level slower than its rated i.e. 4-4-4-12 set to 5-5-5-15, make sure your RAM never exceeds its rated frequency i.e. for 6400 RAM, 800mhz

Nice :p
Anyway, my vcore is at what it already was to begin with, I've already been doing the prime95 tests and such but my only problem is the RAM, I didnt change that at all and have no clue what I'm doing, its Corsair XMS2 4GB DDR2 PC2-6400C5 TwinX (2x2GB) so I'm assuming it should be at 400mhz instead of 430mhz, how do I change it? :(

Does this mean anything to anyone?

It does! :)

You have overclocked your RAM 7.5% above its recommended speed!

Your Motherboards Northbridge is running the 333-Strap

Your FSB is 358MHz (1432MHz System Bus)

Your Intel® Core™2 Duo E8500 if using the default multi is running at 3402MHz which is 7.6% overclock! :cool:

If you go into BIOS and look for something relating to DDR2-Frequency the basic option you are looking for is to run your memory in sync with the FSB, I'm not sure what its called on a Gigabyte board but at your present FSB speed you want to set the memory to DDR2-716 (or 358MHz if its shown that way).

Once you got the memory in Sync you may feel like whacking the FSB straight up to 400MHz and stand by with a fire extinguisher! :D

Were you being serious about setting up the memory to be in sync with the fsb? Your fire extinguisher comment has me wary :p
 
Right I had a peek in the BIOS, couldn't find anything to tie the memory to the FSB but I did notice something called (G) MCH Frequency Latch which was on Auto, although I can put it to 400mhz, is this what I'm looking for?
 
Don't think that's right. You will have the option there, I think it's called DRAM multiplier in gigabyte boards, might be on auto right now. Change it until the RAM is running less than 800mhz so you can up the FSB more.
