I as well as many others have had LLC enabled since I had the option. Never any issues.

xguntherc · 07-02-09

so i should enable LLC.. will that make it more stable? as it seems pretty solid, but I wont know til I let OCCT run the entire hour. and maybe do linX

but not bad 3.33 Ghz with 1.21v on a Q6600.. my 750i NEVER could do that, and it took me endless nights to get 3.33 Ghz stable. lol

you got a low vid cpu like me probly can get 3400 with 1.23 vcrore llc works best for me.

like he said, you can, it's not so big a deal with the 65nm CPUs. It can be prone to spikes, but that won't be a problem until you start going outside of Intel's specs for your CPU vCore.

This table says that, for a given FSB, these are the best Straps to choose.
Memory Strap Table

Unfortunately the P45 chipset does not allow INVERSE Ratios. This means that you will always have to choose a strap that makes the RAM a Higher speed than the bus. So, if you have a 400MHz bus (1600MHz pumped), the lowest RAM speed you will be able to run will be 800MHz.
ok, here are a few links that might help you out. Conversely, and what is bugging me, is that at 550MHz, the lowest you can run is 1100MHz and my RAM is finicky about that... alas. For the most part, you will only be concerned with the B and D straps, I mean, unless you are underclocking.

The first thing you should do, though, with a Gigabyte board is Enter the MIT page and choose Load OPTIMIZED Settings. Then boot into windows, launch ET6 and write down what it says the voltages are- that way, if there are any AUTO's selected in BIOS, you will know what they are.

Now, here is a form we use here to talk about what we are doing in BIOS and what we are hoping to achieve. M.I.T.

You can use ET6's Tune feature to try out an Overclock. However, this tends to over volt things. It is a good way, though to get started. For instance, ET6 might have a 3.6GHz Tune option. Choose it and then when you reboot, go to BIOS and see what it did. You can then boot into Windows and launch ET6 again, run Prime95, and use ET6 to lower your voltages (one at a time, one notch at a time - recording the changes ON PAPER as you make them) till Prime or your system crashes. Then go into BIOS and manually make the changes that reflect the last good values you had in ET6.

For the most part, set Performance Enhance to 'Standard'.

Here are a few links that might be helpful.

RAM Timings
BIOS Flashing - READ THIS BEFORE YOU TRY TO FLASH A GIGABYTE BOARD
Using MCH Ref

So, after reading this, if you have anymore specific questions, we will be glad to help. Keep in mind that we aren't always the most expeditious source though. However, there is an OUTSTANDING Gigabyte support system at play at the links I just cited.

Good-on-ya!!

wow, thanks for all the great info there. I really appreciate it there.

I'm not new to overclocking, just new to Gigabytes boards. That's probably why they are so stable, they don't let you number punch CRAZY straps like the 750i boards do. lol.

So far this 3.33 Ghz 1.21v is working fine. and ram at 1112 Mhz is stable as can be. lol.

I might just set it to 3.4 Ghz and get a good ram speed and leave it be. Seems very easy to get stable on this board. lol. plus the 1.21 VID chip might be helping, when i had a Q6700 on my 750i it was a 1.2875.

I'll post a screeny later with what i end on. I'm ok without loading mobo's own defaults.. I'll try it my way first.

so far I'm liking this board tho..

grishkathefool · 07-02-09

kk, when you post your screen make sure to tuck ET6 voltages into the shot and include a copy of the MIT form filled out in a php code field, for posterity sake...

I didn't mean to come off as if you knew nothing... however, we here are used to people being new to the Gigaworld... We realize that it is different than what Asus and DFI, MSI, and FoxConn users are used to. So we tend to spell things out for them.

In fact, some one oughta come up with a "New to Gigaboards?" faq sheet.
*looks at denny...

Not to mention Grish is a walking Encyclopedia of info. So he can defiantly point you in the right direction you just gotta be able to stare the vehicle.

ach, I couldn't stop my self. sorry Guru.
We could write it in collaboration....

lol 3400 waset enugh for me my overclocker in me is trying out 3700mhz now so far so good kinda hot tho 67c priming with 1.34 vcore 465*8 3722mhz

I dig it, I am still chasing 4.81GHz and Guru is trying for 4.9...
