The thing that throws most people with the gigabyte is the voltage secttion. The bios shows the overvoltage from default settings. That's fine if you know what ther default settings where , but gigabyte leave us to work that out for ourselves
If you look at the MotherBoard Intelligent Tweaker (MIT) post you'll see the defaults :-

DDR3 Overvoltage Control - Stock = 1.5v
PCI-E Overvoltage Control - Stock = 1.5v
FSB Overvoltage Control - Stock = 1.10v
(G)MCH Overvoltage Control - Stock = 1.45v

So to set your kingston to 1.9v you'll set an overclock of
DDR3 Overvoltage Control +0.40v (1.9v - default 1.50v)
the same applies to the other voltages above.

I've not used your Ram so can't really advise you too much. Oner of the best waysd to learn is to check ther timings in the SPD column as they change to match the dividder & FSB set. Use Memset to tweak & test settings in windows.

tRD (performance) has a big impact I usually set it to auto on a new clock & see if it will tighten (lower) with memset. If it doesn't windows freezes , but just reset & carry on. You've found the optimum

The best straps are B & D my preffered dividers are 3.33D & 4.00D which run very stable.

hope that helps

luck

Thanks for the reply supershanks

Can you make a little list of the settings like in your original post please , would make it a lot easyer

Thanks again m8

My point was I can't do a Full bios for you cos I don't have your memory, you also don't mention what FSB & multi your aiming at I've made up a moderate overclock to start you off. Best estimate is this :-

These are my Cas 7 settings , good up to around 1777 as I said earlier I doubt you'll ever manage

i cannot manage my cellshock at cas 7 at 950mhz or more mhz

.
E8500 4,335 8.5x510@3.33D 1,700 7,7,7,12 Has run on both F5A & F5D

I'm hoping someone can help me - I've wracked my brain and can't for the life of me figure out where the problem is.
Yesterday, I purchased an Gigbyte x48-DQ6, Intel Q9300 and a Coolermaster Real Power Pro 850w powersupply.
I installed this in my existing case and used my existing drives; a 250gb SATA drive, a 40gb IDE drive (both Seagates) and LG DVD-RW.
The ram was also new - I'd purchased it from MSY a few weeks ago as part of this upgrade: 2x2gb Adata DDR2 (800).
So I get my new goodies home and put it together with no problems, start it up and it whirrs right to life and posts fine.
Then restarts.
Same thing happens again.
Posts, then before it even gets to loading winxp, it restarts.
So, I went into the bios and everything looked fine, restart the computer and it again starts fine, posts then loops back and restarts again.
At first I thought, even though it was the new ide cable that came with the DQ6, maybe it was a bum one. So I tried my previous ide cable - still looped.
Checked all the jumper settings on my drives, no difference.
Tried disconnecting all drives but the ide drive, no difference.
All but the SATA drive, no difference.
All but the DVD-RW, no difference.
Tried checking the ram by putting one stick in at a time and then repeating this in each of the memory channels, no difference.
So I thought maybe, for whatever reason, a newer bios might fix it, so I downloaded the latest bios from the GB site onto a usb stick and then flashed it using the q-flash utility in the bios.
No difference - still posts fine, memory tests, recognises the drives, then goes to the next screen then restarts.
I tried resetting cmos, leaving the battery out for an hour, both made no difference.
Still posts, recognises the drives goes to the next post screen then loops.
I don't think it can be the drives, because they worked fine before and if the ide drives for some odd reason went bad, that doesnt explain why the SATA drive does the same thing.
I was wondering about the ram-but a search of the internet even had the same ram being used in a review of the motherboard.
I'm worried that it may be the south bridge on the board, as it runs both the ide and sata controllers and that seems to be where the issue is.
Does anyone have any suggestions or ideas?
I've run out of them and now have a splitting headache.
Thank you in advance for any help you can provide.

Works like a charm , ok with Precharge Delay (tRAS) at 25 and prime95 is smooth , no errors and temps are 40 idle and 54 load

Ready to crank it up What can i do ? only increase fsb without touching voltage ? Memory wont like it right ? Newbi here

By the way , can i leave it like that 24/7 ??

Thanks !!

all yuor settings are ok but let me explain with my bad english i am italian sorry

with bios f4 i could not manage ramsover 900 mhz at any cas or any voltages. with f5a its ok up to 1000 mhz 8-7-7-xx but cas 7 there are the same problems of f4 bios. i dont think that my rams cannot support 900 7-7-7-xx.
its not a strange problems because if i do benches i will use 2:3 or 5:8 so i dont manage so high frequencies on rams and its ok
what i wanna say is only that bios can do a little better ^_*

btw its a very good mobo.

@madspec

By the way , can i leave it like that 24/7 ??

Yes add it to one of the Overclocking Profiles. Press [F11} from main bios menu to save the settings. You can use [F12] to load the settings back. It's also worth printing the bios template out & writing up your timings. Or posting your settings here , so you & others can refer to them

Yes I'd try increasing FSB and running Prime. if you find prime fails , check what it fails on. If it fails on small ffts <512mb then it's CPU that iis failing, if large ffts >512mb then it's memory related.
If CPU Fails then increase vcore & retest , If memory try increasing (G) MCH or slackening memory timings, you could increase vdimm but you are currently on kingstons max for your modules, so it's up to you.

So we expect to see you post your stable 4500Mhz by end of the day


luck

@kangaxxpk
your English is better than my Italian , I should be sorry
F4 was the shipping bios and was rubbish for memory clocking F5A or F5D as we've said are best.

You'll probably need vdimm of 2.25v +0.75v and mch of 1.70v +0.45~0.65v to support 2000Mhz at Cas 7

Yes bios could be a bit better , though it's better than I've known on some boards at this stage in their life cycle

[kangaxxpk]

why if i put 1700mhz rams on bios cpuz see 750mhz 2:3 ??

[supershanks]

why if i put 1700mhz rams on bios cpuz see 750mhz 2:3 ??

CPU-Z won't for whatever reason get the 3.33D or 5:3 divider. I use Everest's CPUID to show correct ram speed when using 3.33D

[kangaxxpk]

just an info, how can u know that 3,33D is 5:3 without look at cpuid ??
what is the formula ?
