hi yeah ive just been reading a bit about how timings are just as important as frequency. 4444 mmmmm nice. im stuck a bit high unfortunately 555 15 in most cases.:cool: haha oh well shall keep searching and posting stuff.
peace:)
supershanks you genius !!!:D ( and everyone else too of course:)
ive just been on your forum at clunk.org and read about your (g) MCH V control settings
http://www.clunk.org.uk/forums/revie...q6-blog-3.html
it really stabilises !! wow... o.k ....i've only done 2 tests but, it stopped memtest going mental on me...woo hooo :up:
im adding +.100 at the moment on a low cpu overclock 400x7 (due to only having stock cooling) but it really helps me in memtest.
y see i thought only a few days ago that if your memory fails memtest its either faulty or you have the wrong memory voltage ...but no....its all interlinked memtest can fail due to low cpu voltage and fsb v and nb v too.....coool:) phew:)
hey im only a newbie on overclocking.:rolleyes:
shall be back later to tell all...
Glad it helped :D
My cold boot issue is back again, i get tired of this.
I will flash back to F3 and see what happens then.
If this doesn't solve my problem i will RMA the board and will get an ASUS again.
Cold boot is back again so i reflashed to F3 still same issues.
Now i have F7d again, i think i will rma this board and get an ASUS.

I got cold boot probs before when flashing ,but now I make shure I do a cmos reset jumper after everytflash with this board ,and not a single issue at all.
Worth a shot ,let us know how you go..
I have done that before.Quote:

I also send my reseller an email to exchange the board to an ASUS, but we will see tomorrow. Now it runs like charm at 3.6 Ghz with 1.44 Vcore and 40C idle temps.
yes, that cold boot thing can be a pain in the butt, but i'll live with it. at least until the gigabyte chaps put out a really bugfree bios.
i spent 3 hours last night trying to get the DDR3 board to play nicely with Corsair 1800MHz CAS7 XMS sticks
i even used the XMS profile and could not get them stable at stock
i flashed to a number of different bioses >> F2/F3G/F4a/F5d and all had many problems with RAM ratios. The ratios don't work properly and make the system really unstable even below rated timings.
After a bit of testing i used single sticks and determined which one is fastest and proceeded to test on the RAM slots. I found that the pink slot closest to CPU was by far better than others.....for example i was booting into windows on 1:2 ratio 333 or 400 strap can't remember now and 1st, 3rd and 4th memory slot failed 32M instantly while 2nd slot (or the pink slot closest to CPU) could do 32M no problems and in fact i overclocked the FSB in windows and pushed the stick to 925 which was stable >> 928 stopped on 4th loop.
this was all at 2v which is what this stick is rated for at stock.....
i also tested with the 4GB kit 1600MHz CAS7 which were also struggling
there is a huge difference for me between the DDR2 and DDR3 boards. DDR2 can easily max and surpass my RAM overclocks with any other board i tried and push the RAM to bench at monsterous CAS4 speeds.......DDR3 has many problems with RAM ratios. I will be doing some more testing but i tell you what....if i have to spend a few benching sessions to get my sticks to work at stock timings it's a pretty bad sign....maybe a rework of bios from scratch is needed here donno :( :shrug:
i tested these sticks on GB P35 DDR3 board so i know that can do rated timings easily on both 2GB and 4GB kits :shrug:
i noticed the french team used F4a bios and i saw them use specific straps which i find odd as for me F4a bios does not allow me to select a RAM Ratio at all.....and this was tested with few different CPUs
Did I say the wrong thing ? Wonder why my questions were all ignored.
just flash to F3 bios :)
is the f3 bios the best atm. for this board?
I've have a problem
When overclocking fails, it will not boot again until i remove 3 of my 4 kingston DDR2 RAM sticks?
Link to the memory: http://www.komplett.no/k/ki.aspx?sku...ed#ProductTabs
Any suggestions?
Where can i download the latest beta bios? the F7F one... cornelshs @ gmail . com
Edit:
What bios would you guys use with my hardware?
Gigabyte X38-DQ6
Intel Q6600
4 sticks of 1gb kingston ram
8800 GTX
4x harddrives.
even if you clear cmos? you have to remove ram to boot?
Yes, must adjust the voltage on the vdimm up to 2.3 or somthing before i add the 3 remaining sticks...
I think that this mainboard rocks. Before this I had an Asus NF 650i, which by the way is a pain in the A**. On Asus I could not set the CPU higher than 2,8GHz, and also with the memory, I could not reach 1066 without loosing stability. Another friend of mine has, Asus Striker Extreme (NF680i), and he also has problems ...
Over time I had a bad impression about Gigabyte, because I worked a lot in computer service and assembly, and for a long time gigabyte had many bad boards, but I must say that this board is very good. It has good overclocking capability, it's very stable, good design, it stil offers serial and paralel port (for those who still need it, like me for example :))
For those who wants to go on ASUS, You should think twice before making that move. If you want another X38 Mainboard I advice you to take a look at DFI's LANParty LT X38 T2R :up:
Did a little more overclock :) and now my cpu is at 3,6Ghz 1,525V and memory 1080 2,4V.
Here i am again and i tried my cold boot this morning.
Bad luck still the same issue, bios went on default again.
Btw i use the red memory sockets because my cpufan is right above the first, yellow socket. So i run dual channel on red, does it make a difference if i change to the yellow channel?
I've tried both sets of sockets but not noticed any difference.
What PSU are you using?? A number of people have had issues with Enermax Galaxy 850/1000 & Antec Truepower Quattro (TPQ-850) 850W lately re start up issues.
waku waku :
can you post your settings for the experts on here to see?
to be honest i had trouble at stock values...i could not boot at 266 x9 1066mhz ram.
if you dont think its your settings have you any other ram to try? even if its lower rated
have you another processor to try?
how about the psu? could that be the trouble?
what is your newest component? did you buy all the parts in one go?
or do you know that certain parts definitely work?
do you think its the motherboard? if so can you RMA it?

To whom it may help, here are my Specs and Bios configuration. It took me 3 days, well actually 2 days of reading, collecting information from web forums and a lot of trial and error but I finally got it running and stable, 12 hours prime95 no errors no heat problems (water cooled). I could have gone higher but I wanted to limit the core Temp to below 50°C under max load with prime95.:clap:
I am publishing this with the hope that it may help someone with a similar system setup, I read that the corsair PC8500 is troublesome memory when trying to configure it with this board.
I am quite happy with my system with one exception Everest Memory – read, write, copy - benchmark 64.5, Super PI 32M 14:26 seems very slow,:shrug: if any of you experts out there have a better suggestion for improving my Bios Configuration especially in the sections System Voltage Optimized or Advanced Timing Control, I would be truly grateful. If I can be of help just ask.
Your articles helped me immensely:up:

hi freight hog.
well done
im using the same memory as you . wow did you have problems too?
i was altering the bios then checking in memtest86 before i tried prime95.
it kept failing no matter what i did.
i found out on here to raise the north bridge X (G) MCH OverVoltage Control that helpes allot i'm at this currently below:

i hope that once i get a better cooling system i can simply change the cpu multi to x 8 or x 9
with no problems at all hahaha yeah right.
q6600
x38 dq6
dom pc 8500
and western digital drive
stock cooling :shakes:
hope this helps
CPU EIST Function: is not in the F7d bios!! im gonna try the latest bios on the gigabyte site.
also
just been on the gigabyte x38-dq6 website .co.uk
and it says Dual Channel DDR2 1200 memory support for outstanding system performance. so its not like 1066 is pushing the limits of this board.
when i push my ram over 1066 it always fails at the end of test 5!! why is that?
arrgg!! haha:)
It happens because youre using dual channel. Ill bet if you set your memory to single channel you'll not only be able to run the ram at higher speeds, but also never get the cold boot issue.Quote:

Most ddr8500 memory should do just fine on this board at 2.3v 950mhz 4-4-4-4 timings. Adjust up to 4-4-4-7 if unstable. Make sure TRD is 8 or above no matter what. Also, Use standard or turbo on the performance enhance setting,- extreme is unstable in most cases in dual channel mode.
Most of us are having trouble making this board run stable at ddr8500 with just optimized defaults, just because of this bug. Just reset bios and boot with a single stick so you can set TRD to 8 manually. After that youll be set...
Ive also noticed unstability when upping FSB and MCH voltages. The board seems stable at default values up to 475mhz, so no need to touch'em anyway unless your multiplier is below 8.
