OC with Gigabyte GA_P35C_DS3R & E6420

bloodline76 · 24 Jul 2007 at 20:06

Can anyone help with some overclocking with my MB and CPU.

These are the options:

Robust Graphics booster
CPU Clock ratio
CPU Host Clock Control
CPU Host Freq Mhz
PCI Express Freq Mhz
CIA 2
System Multipler SPD
Memeory Freq
High Speed DRAM DLL Settings
System Voltage Control
DDR2/DDR3 Overvoltage control
PCI-E Overvoltage Control
FSB Overvoltage Control
(G)MCH Overvoltage Control
CPU Voltage Control
Normal PU Vcore (This is greyed out)

Anyone understand What I should set these too? Starting point and what I should gradually increase?

Thanks

Anyone?

theres a sticky allready on the Gigabyte boards!!!
in the motherboard section

Looked at that. I am still lost. lol :rolleyes:

Just read the thread about the DS3 it is basically the same layout in the BIOS as your board.

What should I set my mem timings to? 55518?

4-4-4-12 at least. Check the mem voltage though - Gigabyte is 1.8V default.

If it's running at 800mhz you will probably need 5-5-5-18 or so.

bloodline76 · 25 Jul 2007 at 19:17

And do I press Ctrl+F1 to open mem timings? What voltage does the gell run at? If 1.8 is stock, could i raise it.

Should I use the standard voltage suggestions on that other thread then for my computer?

thanks

I think GeIL runs at 1.8, thats what I've got mine set at anyway. I would only increase the memory voltage if your overclocking it

Check the Geil website for rated RAM voltage, my Ultra Low Latency stuff needs 2.1v minimum. Ctrl-F1 to access settings, check the Beginners guide to overclocking for what to change. Robust graphics booster feeds extra voltage to graphics cards when overclocking them.

Edit: Make sure you set the PCI-E frequency to 100MHz, otherwise it'll scale with the host frequency (FSB) and will limit your overclock very quickly.

Found out what I was doing wrong. Successfully overclocked to 3ghz which is what I wanted and run orthos for nearly 9 hours successfully. Played a few games and seems ok.

Now the temptation is to go higher now...

I left all the voltages the at stock value. Except the cpu which I increased from 1.3250 or something like that to 1.35.

Tempature was around 55max. on tat. Is that ok? Could i push higher?

naudiz · 26 Jul 2007 at 15:20

Plenty o room on that, I think of 65 as the limit, although many will say different I'm sure

bloodline76 · 26 Jul 2007 at 16:56

So 65 would be a safe temp? When you say others might disagree, do you mean they think you can go higher or lower?

Cob · 26 Jul 2007 at 17:01

~60c is considered to be the safe area for the C2D's. 65c is about the sensible limit.

Dharok · 26 Jul 2007 at 17:02

65 is definately a good guide in which to say the max temp underload. Any higher than that and I guess you'll start throttling the CPU.

bloodline76 · 26 Jul 2007 at 17:44

Well that gives me 5 degrees to play with and still be safe at 60. Sounds good to me.

bloodline76 · 26 Jul 2007 at 20:15

Up to 3.2ghz. temp running 54-59 underload from orthos.

iMacMart · 26 Jul 2007 at 20:23

Sounds OK

I got mine to 3.4ghz Orthos stable

Same board and same chip

In reality they can go much higher than that!
