I can't get my Q6600 G0 stable @3.4ghz !!

post #1 of 6
Thread Starter 
my current OC is 9x356 @1.376vcore with my ram downclocked to 712mhz to make it 1:1 ratio. why downclocked it ? coz one of the core (random core) would fail prime95 within 2 minutes if I dont downclock it. Per research, my memory is capable of 2.5v (2.2v default) and 1000+mhz on it...

so I tried pushing it to 3.4ghz last night with 8x multiplier and 9x multiplier. one of the cores fails within 1 minute in prime95. I tried increasing the vcore all the way up to 1.489v as well as the memory to 2.3v and NB +.1. none of them helped what so ever. one of the cores still fails within 1 minute in prime95....

here comes my question:

1: do you think replacing the rams with some Gskills would help?

2: replacing the mobo perhaps ? (in this case, which mobo ? prefer under $150)

3: besides swapping parts, is there any other particular way that you want me to try in order to get it stable @ 3.4ghz ?

THANK YOU !!

clock your whole system down to stock everything... run memtest overnight - I'm guessing you might have faulty ram

Try these settings. (originally posted by ericeod)


To get 3.4GHz-3.6GHz with your Q6600 assuming the CPU can handle 3.6GHz at 1.5v or less (this OC is very doable with these settings). These arent difinitive, it is all based on the CPU, but these settings are solid for the board itself and should get you started.

Advanced BIOS Features
CPU Enhanced Halt (C1E) Disable
CPU Thermal Monitor 2(TM2) Disable
CPU EIST Function (Note) Disable

MB Intelligent Tweaker(M.I.T.)
CPU Host Clock Control Enabled
x CPU Host Frequency (Mhz) 400 (this is for 3.6, set yours at 3.4 first)
PCI Express Frequency (Mhz) 100
System Memory Multiplier (SPD) Set this at 2.0,2.4, or 2.5. Depending on how high you want. I would start at 2.0

System Voltage Control
DDR2 OverVoltage Control: +.03v (default is 1.8v)
PCI-E OverVoltage Control [Normal]
FSB OverVoltage Control +0.2v
(G)MCH OverVoltage Control +0.2v (This is your northbridge voltage, might need +0.3 when running over 400 FSB with quad)
CPU Voltage Control 1.40v - 1.5v (it might need less then 1.40v, or it might need a bit more... only testing will tell)

Depending on what bios you have, you might have to press [CTRL+F1] in the main bios menu to access advanced memory timing options.

i dont think its your memory failing you, is 1.37v set in bios or is that what cpuz reports in windows?
if thats in ios, then vdroop puts you near stock, most chips wont run 3.4 on stock volts, my stock is 1.22
if its in windows, try increasing vcore a little more, or try upping NB volt a notch

i've tried this very setup from you once before. it didnt even boot into BIOS. then I asked some other guys and they recommended setting the NB and FSB back to default. and that didnt help either.

The 1.37vcore is per CPUZ in windows, the actual BIOS vcore is set to 1.425v.

when I was trying to get it stable at 3.4ghz, CPUZ was showing 1.489v and in BIOS it was 1.55v.
