so what happens if you try the 3200 as post#723

Hi Super,

I started small FFTs at 1.425v, then I got stable in small FFTs at 1.4v and I got also my most ever higher scores in 3DMark06 and 3DMark Vantage with this last vcore (I didn't change or install anything else in my rig):

3DMark06 (trial version)--> 18062
3DMark Vantage Advanced--> P12873

On load, with 1.4v, my temps are roundly 70ºC. Is it too much for my CPU?

As I told u before, the next lower vcore value after 1.4v (that I can remember now) in my BIO settings, I got also stable in small FFTs, but with lower scores in 3DMark06 and 3DMark Vantage with corrupted graphics in this last one, than I have before when I had set a vcore of 1.4v.

Thus, I got a decrease in my rig performance. Why???

Your suggestions are welcome!!!!

Voltage doesn't have any effect on your benches.
Depending what benches you run there can be variation between runs. Are you sure that for example a graphics overclock was included in in run & not in the other?

It's ok for the occasional overclock, but i wouldn't run it 24/7. I tend to like a max load temp of around 65C , but it' s your shout. You'll probably be there with the sub 1.40v setting.

Same thing, POST fails and reboots. I'm almost positive literally any setting while the CPU clock control is set to manual causes this.

Understood.

I'll keep lowering vcore and then I'll come back to show my results.

Well it's something I've not seen. What revison is your board v1.0 or v1.1 ? It might be worth looking here
Gigabuyte Global Technical Service and contacting support, they are pretty quick with responses.

Sounds like a plan

Hi guys! Nice to finally find a forum with such a great knowledge about the X38-DQ6

I have my DQ6 for like a year now and have had several CPU's running on it. Hasnt let me down so far Yesterday i got myself a q9450 and offcourse i wanted to overclock this baby. The problem is that i can get it rocksolid on 3.4ghz with 1.27 vcore but it seems like everything above wont even post! I have tried a lot of things, raising the vcore offcourse, the FSB & PCIE... nothing seems to help. Could this be my processor or the board which hit a wall??

My current settings are:
MB Intelligent Tweaker (MIT)
Robust Graphics Booster: Auto
CPU Clock Ratio: 8x
CPU Host Clock Control: Enabled
CPU Host Frequency(Mhz) : 426
PCI Express Frequency (Mhz) : 100
C.I.A.2: Disabled
Performance Enhance : Standard
System Memory Multiplier (SPD) : 2.00D
Memory Frequency(Mhz): 852
DRAM Timing Selectable : Manual

Standard Timing Control
CAS Latency Time: : 5
DRAM RAS# to CAS# : 5
DRAM RAS# Precharge : 5
Precharge Delay(tRAS) : 15

Advanced Timing Control AUTO

Clock Driving and Skew Control
CPU/PCIEX Clock Driving Control : 800mv
CPU Clock Skew Control : Normal
(G)MCH Clock Skew Control : Normal

System Voltage Control : Manual
DDR2 OverVoltage Control : +0.20v (2.00v)
PCI-E OverVoltage Control : +0.05
FSB OverVoltage Control : +0.05v
(G)MCH OverVoltage Control : uhm.. the first + option lol
MCH Reference Voltage Control : Normal
DDR Reference Voltage Control : Normal
DDR Termination Voltage Control : Normal
CPU GTLREF1 Voltage* : Normal
CPU GTLREF2 Voltage* : Normal
CPU Voltage Control : 1.27500
Normal CPU Vcore : 1.2500

Perhaps i'm missing an option which i should clock higher to get beyond 3.4? Would be crappy if i couldnt get it higher couse at the above settings the CPU idles around 30C and max load temp is 55C (after 1.5hour prime95)....

Thx in advance!

Hi StyX,
Welcome to the forum.
You might try
Changing

CPU GTLREF1 Voltage* : Normal
CPU GTLREF2 Voltage* : Normal

both to -3 , it worked fine with my wolfdale, it may help with yours.

I'd up

(G)MCH OverVoltage Control : uhm.. the first + option lol

a couple of notches.

I'd be inclined to try your ram at 2.40B giving a slight overclock.
You might find this thread of eva's useful 2x2GB G.Skill F2-8000CL5D 4GBPQ 5-5-5-15 for fetting best sub-timings.
Use this to translate memset to bios if you need it Memset to Bios translation

Hopefully some of the above will help , let us know how it goes

[StyX]

Thx for the quick reply!

Im going to my girlfriend now so i will try it tomorrow Can you tell me what the
CPU GTLREF1 Voltage* : Normal
CPU GTLREF2 Voltage* : Normal
does? I dont have a clue....
