Overclocking an E6550?

Ok so ive read a few overclocking threads and i understand a lot of it but some of the hardcore technical stuff does go over my head.

ive never overclocked a CPU before and looking into trying it, not necessarily at this point for maximum overclock just mainly for practice and understand/learning how to.

How is my system when it comes to overclocking?

How much overclock could i possibly get w/ a E6550?
Also how much w/out touching voltages? Guesstimate???

Im planning on upgrading to a Q9550 soon so this would be just for fun and practice and not for long term use.

My ram is 1.8v G-Skill DDR2 800 and its also running 5-5-5-15 timings.

From what i have read (please correct me if im wrong) i would start with these steps to achieve a mild overclock of 2.8ghz. Reason im choosing 2.8ghz because anything over a 400FSB then i would have to start overclocking my ram too correct? System Specs are in my sig.

(Again im trying to learn how to OC not achieve a maximum OC at this point in time)

1. 400 FSB (or try a lower fsb first?)
2. PCIe @ 100mhz
3. CIA2 Disabled
4. Performance enhanced to Standard (currently @ turbo)
5. System memory multiplier at 2.00 so that memory is FSBx2=800mhz

Then would i try and see if it posts? can i leave everything else left alone or on Normal?

Bios shots




Anything need to be change on these bios pages?



 
yeah, you basically have it right. Set the FSB, and the DRAM ratio (1:1 means 400FSB and 400Mhz DRAM = DDR2-800). Bump the voltage if it isn't stable or doesn't boot. Clear CMOS and try again if you have to.
 
Thank you for helping.

Is their any other voltages i would have to touch besides the Vcore if it doesnt boot?

How do i know where these voltages should be set at?

I hear some get these processors up to 3.5ghz so would i be having to mess with the voltages that much if overclocking to 2.8ghz?

Or does it usually not matter on the size of the OC most voltages will have to be change regardless?

try these rough values.

400x7
1.35 vcore
1.35 vmch
1.30 vtt
1:1 mem/fsb ratio

Thanks for the help spikesoldier

Ok im guessing that the VMHC is most likely the one lable (G)MHC overvoltage control?

Vcore would be CPU voltage control? My current Vcore is 1.316 correct?

And VTT is.....?

Now when i change these voltages from normal to X amount will it state what Normal voltage is so that i know how much im increasing it by?
 
So this is where im at now to do a 2.8ghz OC on a GA-P35-DS3L

1. 400 FSB
2. PCIe @ 100mhz
3. CIA2 Disabled
4. Performance enhanced to Standard (currently @ turbo)
5. System memory multiplier at 2.00 so that memory is FSBx2=800mhz

Then would i try and see if it posts.

If it doesnt post the remove CMOS battery for a minute or so and then reboot. Go back into bios and fix all regular settings from default.

Then go to the Motherboard Intelligence Tweaker to adjust other settings

i have these listed to adjust voltages.

System Voltage-Leave at manual

DDR2 Overvoltage- Can select from a +0.1 - +0.3. My Ram is 1.8v with a max volt of 2.0. So a + 0.2v would be maximum overvolt

PCIE Overvoltage- I think i would leave on Normal (set at 100mhz at top of MIT). If i cant get it stable after ive tried everything add a +0.1v Maximum?

FSB Overvoltage- Is this the Northbridge overvoltage? Can add a +0.1 - +0.3v

MCH Overvoltage- Is this the Southbridge Overvoltage? Can add a +0.1 - + 0.3v

CPU Voltage-Currently at Normal- 1.296v (CPU-Z) to Bios Vcore of 1.314.


Are these the only voltages you have to mess with when overclocking on a Gigabyte board?

REFER TO BIOS PICS ABOVE. THANKS
 
Yea there is how to's but they are not answering the questions im asking.

1. Are these the only voltage controls for overclocking on a gigabyte board that i have to worry about?
2. Are those 2 controls listed for the Northbridge & southbridge overvoltage or is it overvolting something else?

3. Do my steps seem correct or there something that you would change?

4. MOST IMPORTANT- This is a forum and you supposed to answer peoples questions so they can learn. IF you dont want to do this then why are you on a forum?
 
Some one on a different forum just explained that

MCH is the northbridge overvolt and FSB overvoltage is VTT.

So questions 2 is explained

I was only trying to answer your question on why you weren't getting replies. Please don't attack me just because you didn't like my answer.

I'm also on this forum to learn. ATF doesn't exist solely for your benefit.
 
The forum is supposed to be for everyone benefit but it doesn't benefit anyone when simple questions cant get answered.

Maybe Im just use to the truck forums that im on. If you ask a questions its answered immediately by multiple people but here it seems to just be overlooked. Especially w/ 200 views.

Also there are many other overclocking treads where people are helping other. I dont think my questions would be that difficult to answer.
 
well, i'm running my E6550 @ 2.8 with only +0.1v to the DDR2 (now @ 1.9v). thats all it took. (400FSB, 1:1 ratio of course)
in the winter i'll try to go higher as ambient temp will drop a little.

currently with ambient around 28C i'm idling around 33C with my CM Hyper212 (old one).
and load never goes above 50-53C
 
E6550 or 65m was a topic 4 years ago at the time I had e6600 680i.
Do a search and you should find everything.
I build new PCs for the fun of setting it all up by my self and only after I tried and got a good overclock do I post and ask questions.
How can you learn anything by putting in numbers that were given to you.
 
No those are the numbers that i pulled out of bios but it doesn't matter i finally found a huge thread with a ton of info so i think im good

I also wasnt asking what numbers to plug in for a successful overclock. I was asking if these 5 voltage setting were the only ones i have to change while overclocking.

I was also asking if steps i wrote out for overclocking looked correct because these are the steps that i plan on following.

Thats awesome man, thats exactly what im going for. Did you bump up the vcore or is it still at stock?

Ok so i successfully got my E6550 OC'd to 2.8ghz by only doing these steps. So far i haven't changed any Voltages but cpu-z showed my Vcore at 1.296 @ stock and 1.312 @ 2.8ghz. EDIT: CPU-Z did show me a higher Vcore at first but i did open and close the program a few times. Maybe thats why the pic shows the same as stock Vcore or i was just seeing things.

1. 400 FSB
2. PCIe @ 100mhz
3. CIA2 Disabled
4. Performance enhanced to Standard (currently @ turbo)
5. System memory multiplier at 2.00 so that memory is FSBx2=800mhz

So if i didnt change any voltages is the comp still considered stable?

I have prime95 and i go to options then torture test. After clicking that it gives me a couple options, which one do you guys choose.

I tried one test on stock Ghz and i selected "blend"

The simple process for overclocking applies to ALL boards regardless of manufacturer.

1) READ
2) Try It
3) Profit?

That said, if you have GOOD components, try for 500fsb. My 6550 had no problems running at 500 fsb (it is hard on the ram though) and it actually ran there with less volts than it took to get 400 stable.
 
I hate this about internet forums. Can't ask any simple questions because someone will just say "search button". Overclocking on those boards was simple. Increase fsb, run ram 1:1, increase voltage to cpu if needed and you're done.

Thanks a lot man
Cool thats what im trying right now. I will post up with more info soon.
 
Ok Update i just tried a 429fsb x 7 =3.0ghz and it booted to windows fine. I didnt change any voltages at all. I sure i will have to and thats what im going to play with now but i think 429fsb is pushing this system far enough for me right now. Plus my ram is already overclocked to 858mhz. So from this point i think i just want to try and get the 429fsb stable.
 
I was recommended to try HyperPI for stress testing on a different forum. I tried it first to help dial it in since it only takes 30min roughly. The first test i did was a 400fsb and all stock volts. It got about half way through and then had an error. I upped Vcore to 1.325 from stock 1.314 and it got fully through the test.

Ok well i set the FSB at 400 like i said and upped the vcore to 1.325. I ran HyperpI and it completed the test. Heres the pics.
