Official Gigabyte X48/X48T-DQ6 bios+info thread

[astrodave]

Can anyone provide me with o/c settings for an e8400 on a x48-ds4 rev 1.3? I am trying to find some sites online with the settings i need but am not having much luck with this board. Thanks if you can!

[jaggerwild]

Anbody know why/if this board has a hard time reporting multi's? As when I'm over clocked the CPU-Z will not always see the correct one, I was clocked to 4.6Mhz with a multi of 8.5 and FSB of around 545. Only way I knew i was at that clock was the bios splash screen, is there a fix for this or patch?
My cpu is E8400, maybe they are the issue and I'll look like a dumbie here?

Again any help is great!
Thanks in advance.........

[Supershanks]

what version of CPU-Z are you running??

[zoolio]

Is it safe to flash the x48t with the BIOS provided on the Gigabyte website now? it is dated 21/07/08

[jaggerwild]

what version of CPU-Z are you running??

1.46, the latest I think?

[jaggerwild]

WOW,
This thread died like my raid after trying to go over the 500FSB limit with the Intel controller chip! RMA, and up for sale. 5 lost raids has me in a not so liking Gigabyte boards mood.

[Ace-a-Rue]

were you pushing the PCIe bus speed also???

[jaggerwild]

were you pushing the PCIe bus speed also???

Nope, It will still clock with a none raid but...........

I had them to 103 or just above that I think on my 4.65 run maybe 104. Why over clocking the PCIe will cause the loss of the raid or OS instabiltiy? I'm not using a raid card like yours.

[Ace-a-Rue]

did you use the Intel Raid or was it another form of raid?

[DjLeco]

Wich is the max FSB achieved with GA X48-DQ6?
Mine doesn't want to pass above 530 FSB, with any kind of voltage on MCH and VFsb.
I tried with one to four mem sticks(1,2,3,4 Gb of ram),and allways the same.

Any good settings?
I use Bios F7 (official)

Can someone post better results and settings for it?

X48 chip, achieved more than 600+ Mhz on Asus Boards,what's so bad with Gigabyte mobos?

Yeah I have been around the 530 mark or so........If you have exceptional cooling(NB+SB Mosfets) then you may find higher.........

@ ace, no other harware using a Intel raid driver. I have contacted Gigabyte to RMA it. mean while I'll play with my BioStar TPower I45 Gonna sell the Gigabyte afterwards not into the RMA stuff too much any more.

Thanks for fast answer, but WHY Gigabyte X48-DQ6 performs so bad, only 530-535 Mhz FSB?

Other motherboards,Asus Rampage by example, have also same chipset(X48) ans same stock air cooling, performs much,much better.
Wich is the explanation of those MB's wich performs better than Gigabyte?

I wouldn't say very bad, it is more of a finesse thing. I'm kinda brutal so there is no finesse with me. You can adjust somethings in hopes of achieving a higher clock, also with the chips I have had really do not need more I just like to get more.

I had a nice over clock tonight on the E8400@ 4.66 or so(had it higher) and all of a sudden I hear a cap go POP.
Now I can't even clock much at all, so I gotta take this whole thing apart now. And send it in, fun............

OPPS sorry missed the T after the X48, not sure on that one.

YES!

on several boards i saw the Intel chipset drop offline when setting 120 Mhz on the PCIe bus speed...was wondering if you were really pushing that bus with high Mhz.

Biostar is a NICE board with a dual core cpu...it gets a little tacky with a quad.

When you say tacky, what exactly do you mean? As I would like to use my
Q6600 on it also.

On the X48 I went with like 105 on the PCIe bus speed, Last thing that happened to it was I was using AMD GPU tool to clock the GPU'S with and I heard a POP sound from a cap some where? It will not clock now so, must have been on the board.It will be a few days till I get the Biostar up and running, still have to remove the X48 first. See you over in that thread.

Hi all

I've been overclocking my comp over the last week for the first time and I'm still pretty lost in regards to this RAM multiplier/timing thing. When I log into the BIOS I see:

CPU CLock Ratio x9
CPU Host Frequency 377
System Memory Multiplier (SPD) 2.66D (This is the part of the settings options that confuses me – I've listed the options I have below)

2.00A, 2.50A, 3.00A, 4.00A, 2.00D, 2.66D, 2.00B, 2.40B, 3.20B, 2.66C, 3.33C, 4.00C
x.xxA -> FSB 266Mhz
x.xxB -> FSB 333Mhz
x.xxC -> FSB 200Mhz
x.xxD -> FSB 400Mhz

Memory Frequency (Mhz) 800, 1005
DRAM Timing selectable 5-5-5-15 (Does this seems right?)
DDR2 Overvoltage Control +30
CPU Voltage Control 1.4+ (I'm still lifting this trying to get it to be stable?)

What I'm trying to understand is what I should change the System Memory Frequency too, to get the best use of my RAM and if and how I should change my timings to make my system more stable. I ran memtest and I had no error but beyond that I'm really unsure of what else I should do? I've put a picture of my setting through CPUZ so hopefully that makes it clear.



My system spec:
Q6600
X48-DQ6
5128800GTS
2x2GB OCZ DDR21066
Antec 850W TruePower Quattro
V1 Thermaltake

I've read about a dozen guide, but this RAM thing just wont seem to make sense to me. Thanks in advance for any help you can offer.

If you know of any other sites that explain it for a beginner to feel free to link them. I would love to actually understand what I'm doing!

Cheers

Mick

well, the 9650 version variety is tricky to get the memory timing to allow for high FSB...i can do 500 comfortably but 510 is giving me fits for stability running the 3D benches, at the moment....i'm still plugging away at the meory settings to see if i can get 510 stable at 8x

445 FSB is no problem and then using a 5:6 memory ratio

[Supershanks]

Have a look here Intel Overclocking Guides.

I'm still pretty lost in regards to this RAM multiplier/timing thing

but it's quite simple. If you rthink of a car & a gear box. The wheels of the car rotate in a different rate to that of the engine , depending which gear you are in.
just as you have 4 gears 1st to top (4th ot 5th) so you have a divider
see

THe gaers are shown as the divider row, If you look at the B column you see 4 values , these are effectively 4 gears:-
2 means that the memory will run at 2:1 eg FSB=400 Ram speed = 800
this is the lowest gear effectively 1:1 cause DDR means Double data rate , 2x fsb
the other gaers or values mean that with the same 400FSB for example
ram will run at
2.4x400 = 960
3.2x400 = 1280
4.00x400= 1600

Now just as formula1 has different gear boxes to suit defferent tracks Intel have different steppings (Columns A~D) to match the stock FSB of different CPUs,

[mackhina]

Thanks a lot for your help Supershanks, that does make it a lot clearer! I can now do the calculations

So currently I have my FSB set to 377 (FSB Quad 1508) and my Memory divider is set to 2.66D; so I get 1002Mhz with a FSB/DRAM of 3:4. So with 1066 RAM in my system this would be the ideal setting right?

The only thing I’m not sure on is if it’s it more important to have more similar dividers e.g. 1:1 or have my DRAM frequency closer to my RAM specifications e.g. DDR21066?

If it was more important to have my FSB/DRAM set to 1:1 then I would have my FSB set to 377 , memory divider set to 2.00D; so I get 754 with a FSB/DRAM 1:1)?

Which would give better performance? I’m aiming to get the highest/most stable settings I can achieve.

Thank in advance for the extra help!

Cheers

Thanks man but I will go with an E8600 Edit for now

Hey Ace,
I can't find your thread for the BioStar board can you link it? I am having a hard time clocking with it, actually clocking at all (so far) other than auto.
Thanks in advance and Thank You for the work you put into the BioStar thread as it is very helpfull for everybody too!!!

So you know, two rads on the CPU. Good ambient temps, A/C going I have a current showing of 15 off the motherboard display .

hey im having some problem with my ds4 rev 1.3 get to 3.8 it keeps crashing after a couple minutes
