GA-X48T-DQ6 + Q6600 OC - Is it possible?

post #1 of 42
Thread Starter 
Ok, what I thought it was going to be a challenging but great experience became a very frustrating one...

I've tried everything that people told me, including overclockers that have the same hardware setup I do. Everything failed...

Then when I thought that I was doing the right thing, specially passing the 3.2 Ghz mark, it all went backwards and now I've decided to stop, re-group and start from scratch.

My system in my sig. I tested my CPU to the top, temperatures are pretty low with my water cooler.

I am aiming for 3.6Ghz and I don't think I should pass 1.55V Vcore.

If anyone has a suggestion it would be great because I ran out of ideas and my expertise is low.


Thanks in advance.

What were your settings and I'll try and give you a hand. I won't be up much longer though as it's almost 6am here and that's late even by my standards With your configuration, unless you got a really crappy chip, 3.6 should have been pretty doable.

Ok thanks.

I tried 8x 450 initially with 2.00D on SPD.

NB/MCH +0.025

Vcore 1.55V

Static tRead Value 10

Command Rate T2

Anything else you need?

X48 chipset can kick a Q6600 around a bit.

Grab CoreTemp and CPUz and post a screen shot of it in here (one big enough we can read thank you...people been posting small screen shots lately). We need to know 2 things:

1 what is the revision - G0 or B3
2 What is its VID.

Once we know these 2 things we can give you an idea what you can get from them. B3 don't expect anything higher than 3.4 without stupid high voltages and tones of heat.
G0, expect 3.6-3.8 on air depending on VID and what voltages you need. Also what cooling you got.


Also please post the settings you got and we can help you out more.


We need more settings than that.

Like this: (which is your board BTW). Please edit the settings below to what you got

Robust Graphics Booster___________ [Turbo]
CPU Clock Ratio ____________ [8]
Fine Clock Ratio ____________[0.5]
CPU Host Clock Control_ [Enabled]
CPU Frequency____________[3.41Ghz(402x8.5)]
CPU Host Frequency (MHz)__________ [402]
PCI Express Frequency (Mhz)_______ [100]
C.I.A. 2__________________________ [Disabled]
System Memory Multiplier (SPD)____ [Auto] works with 1333, I think I want 4.00D/B/C to get 1600 but it posts errors in memtest. Oddly enough 4.00A never boots with this combo. To be clear, I've never gotten any of these settings to work right unless it underclocks the memory. Underneath this SPD selection is two frequencies shown, the left column always shows 1333 as that's the AUTO setting and I believe the right shows the actual frequency, unsure on that get back to me because I realized with my 402 FSB it's showing 1340Mhz here, not in memtest of course(shows DDR1198), and it's stable.
DRAM Timing Selectable_______ SPD __ [Manual]

Performance Enhance = [Standard]
Memory is rated for 7-7-7-20 1600Mhz Intel XMP, 7-7-7-20 works fine at 1333, have tried relaxed settings though which I'll put below.
CAS Latency Time________________ 9
Dram RAS# to CAS# Delay_________ 9 These are the Auto settings BTW, I keep it at 77720 for now try these when doing 1600
Dram RAS# Precharge Delay_______9
Precharge Delay (tRAS)__________ 24

I've never changed any of these settings past the defaults as I have no clue about them.
ACT to ACT Delay (tRRD)_________ 4
Rank Write to READ Delay________ 5
Write to Precharge Delay_________ 10
Refresh to ACT Delay______________ 60 These are all the Default/Auto values
Read to Precharge Delay__________5
Static tRead Value_______________8
Static tRead Phase Adjust________ [Auto] = 0
CMD Rate__________ 2T (only thing I changed, Auto sets it to 1T and this RAM calls for 2T)

CPU/PCIEX Clock Driving Control [800mV]
CPU Clock Skew Control [normal]
GMCH Clock Skew Control [Normal]

System Voltage Control____ [Manual]
DDR3 OverVoltage Control__ [+0.40V] to achieve 1.9V the req. voltage for this set
PCI-E OverVoltage Control_ [Normal]
FSB OverVoltage Control___ [+0.25V]
(G)MCH OverVoltage Control [+0.050V]
CPU Voltage Control_______ [1.25625]
Auto vCore was 1.28750

Limit CPUID Max. to 3.....................: [Disabled]

Hi Lord,

Yes I fixed those images, I think you didn't check afterwards but it doesn't matter now.

I would happily post the CPU-Z image but nothing worked well after I started running Prime95 (I tested with ibt until 3.2Ghz and then Turrican9 mentioned that ibt doesn't do a great job apart from heating up my CPU).

With that being said I am ready to re-start and I would like to have some suggestions on how to get it going again, little by little and what areas of my BIOS setup I have to keep tweaking up.

I have been told that I should be focusing on CPU OC 1st and then RAM. Do you agree with that?

As it is in my sig, my Q6600 is G0 and VID is 1.300V

I personally ignore RAM until my CPU is stable. I'll find a guide as it'll say everything better than I will and explain things better. I was about to explain but realised it'd take ages and I'd just be reciting whatever guide I read day one

Edit: I officially suck at google, I can't find a good guide. Basically go up in small steps if you're overclocking anything. To start, run your RAM below stock, use the 6x multi and just focus on getting the most FSB you can out of your chip, stressing with prime 95 large FFTs as you go along. I never used a gigabyte X48 so I don't know what sort of voltages are okay or anything but Northbridge voltage, VTT and PLL voltage are what will affect FSB stability if I recall correctly, it's a while since I OCed my Q6600. When you've worked out your max FSB you can then start overclocking your RAM. Honestly I'd ignore clocking the RAM if I were you and focus on getting the system stable while staying within the RAM's rated speed and timings. The reason you find your max FSB and stay at RAM speeds you know your RAM will do is because that way, if your system is unstable, you can assume they aren't the problem. That's why it's better not to OC your RAM and CPU at the same time to start with. Sorry, I'd type more but I'm going to bed. I'm subbed anyway so if I can find a good guide I'll post it tomorrow

Thanks mate that sounds like a good start, I'll keep walking slowly until I can reach a stable system.

post #8 of 42
agreed... the x48 chips are a pain in the a55 to get stable... i had such a problem getting my chip stable at 4.1.


i had to throw so much volts at the north bridge to get it right and when i did temps went so hig and i hit 100 on the cputin easly so i had to make a plan for cooling that. after finding a fan that fits on my board it reached 87 degree cell and cpu was at 75 i was happy.

but yeah do your cpu first then work on your ram later.

keep your ram below stock, so it is a lot easier to diagnose problems

it sounds stupid as well to say this... but if you got the game dirt 2... use that as a program to see if you are stable...

works very well... if it is glitchy then your clocks are unstable..... end of story

Yes, x48 seems to be a b***tch. I pushed this thing as far as 1.7V @3.6Ghz but it didn't hold stable. From that point I knew I was missing out on something else and decided to back off and regroup. Temperatures were at high 60s which amazes me how efficient the H70 is.

Now I've re-started the whole CPU OC process and so far I have reached 2.8Ghz stable, increasing 20 FSB every time I get a stable result.

If it get too hard I might just forget about it and get a new board and CPU. My wife is needing a spare computer anyway so this system will be ideal for her.

Well... I am not giving up yet (as I almost felt like), so I'll continue working on it.

PS: I don't even want to think about the RAM yet! lol.
