E6750 + GA-P35-DS3L basic tweaks

[j0j081]

I've been using my new system for about a week so far. Loving it's stock performance, night and day compared to my old socket 754 A64. Now I know everything is working properly I figured might as well start tweaking it a bit. Here are a few of the ideas/questions I have so far...

1. What do I need to overclock to run my cpu and ram at a 1:1 ratio? Will I be able to do this without bumping my vcore (which I hope)? If someone can tell me the exact settings to change that would be great because this is my first ever significantly overclockable system.

2. In the Gigabyte bios I notice there are different performance options such as "Turbo" which is the default, and "Extreme" which says it will run the system at it's best performance level. Does Extreme mean it will be automatically overclocking? I don't really understand what this does, same thing for the Robust Graphics Booster.

3. Using Everest my cpu temp is usually idling around 26-27 degrees but the individual core temps are in the low to mid 30s. Which do I go by when judging how my temps are and are these temps any good for stock settings? I have the AC7 cooler with PWM enabled in the BIOS which is running the fan at about only 600 rpm. Should I set the fan back to auto?

4. Finally is it recommended to leave the power settings in the bios to the defaults, like the things that enable speedstep?

Thanks.

Did you read the sticky at the top of this forum about overclocking Core2Duos and Core2Quads? It doesn't sound to me like you have, and you should definitely read through it before you get started. It should answer most of your questions.

1.) The setting for that mobo (just built it w/ a E6550) to run you ram 1:1 is 2.00. Running your ram in sync w/ the FSB wont req you to bump up Vcore, running a higher FSB will req you bump up Vcore.
2.) I wouldn't user turbo or anything (leave things on normal/auto except RAM freq, and voltages you may need to adj.). No, the motherboard isn't going to overclock itself. Read the manual, it will describe these settings to you.
3.) You really should read that OC guide, and if you have reread it for specific questions like this.
4.) Totally up to you.
I was able to get up to 466FSB with this board everything running on stock. At 513FSB I needed to have Vnb @ +.2V for Prime95 not to freeze the system.

Read the following, its all about your motherboard

Legion hardware GA-P35-DS3L

You should easily be able to clock your E6750 to 3.2GHz on stock volts all over the board.

yeah I know there is A LOT of info out there on my hardware but that's the thing...there is almost too much to read through in a reasonable amount of time. Was just hoping to get a few quick answers on what I posted as I missed the main boat when everyone else was figuring this stuff out.

Well you are not the only one, I waited five years untill I upgraded recently, 3 months ago now.

Did you read the link I showed you?

anyways, all you need to do to reach 1:1 overclock with your E6750

1- cpu host frequency @ 400
2- pci-e express @ 100
3- system memory mulitplier @ 2.00
4- memory frequency @ 800
5- leave all your voltage @ stock

This should result in a 3.2GHz overlcock with a 1:1 ratio.

At your prelimenary overclocking venture, you might want to turn off EIST and C1E. After you find your cpu Stable @ 3.2GHz (1:1 clock with stock volts) you can turn EIST and C1E back on for cool operatins and power savings when your cpu is @ idle.

But as always, do this at your own risk.

thanks, just out of curiosity how does your ram run stable at only 1.9 v? I have the same kinda and it seems to only be stable at 2.1 which is the recommended.

There is some VDroop for the RAM voltage as well... I set my RAM at 2.0 (min recommended), same as yours, and it shows u pas 1.92 in the BIOS (same board by the way, just OCed a E4500 to 2.93GHz on stock voltage)

The overclocking guide stickied at the top of the forum isn't that long. I'm suggesting you read it for two reasons. First, you're playing around with expensive hardware. You ought to make sure you're doing it properly. There are things you should probably know besides the questions that you've asked. Second, your questions are answered in that guide.

@ PhunkOne - Have you verified with cpu-z that your overclocked processor is actually returning to the 6x multiplier when idle? Mine doesn't on the P35-DS3L. System is perfectly stable, EIST just doesn't work w/overclocking for me.

Yes I can also confirm that speed step works on the DS3L in OC state- mine at 412 X 8 drops to 412 X 6

To OP in the long run you will want to read the sticky in detail - too many people want to get there at the flick of a switch - it took us years to get to this point (and even then we are still learning). Before I venture into any new hardware I do a lot of research until I am sure what I want (I never ask questions just research). Once I know what I want I start downloading all the latest bioses, drivers etc and burn them off to a CD and prepare for the HW when it arrives - this way I do not use the CD that comes with the HW since it is already out of date. Then my OC begins already knowing where I want to get to - a lot of up front research pays off in the end.

Well my ram is rated @ 4-4-4-12 @ 2.0-2.1V. Everest and cpu-Z says it is running at 1.89V. I just rounded it up. my ram is set @ stock volt in bios. I might have to flash to the newest BIOS to get a more accurate reading? But that will have to wait untill I have my new hardware, and I am not completely done upgrading yet.

Yes, I have both EIST and C1E turned on. Running 3.2GHz on load, when idle, it turns back to 6x multiplier resulting in 2.4GHz and lower voltage. Both CPU-Z and Everst shows my cpu throttles down to 2.4GHz with a 6x mulitplier

oh okay well thanks for the tips everyone. I will just read through some of those threads u suggested anyway then.
