Intel Q6600 + GA-G33M-DS2R Overclock issue

[SteveJK]

I tried lots of combinations with MCH and FSB voltages... I think what hayder says, here are the voltages:

BIOS: 1.4125 V
HWMonitor Min: 1.30 V
HWMonitor Max: 1.36 V

P.s.
I thought about this motherboard: GA-EP45-UD3R

I just need 1 PCI-E x16 2.0 and DDR2 (800) compatibility. I thought about the G45 because it's really useful a basic VGA to use in case of VGA change or issues...

 

[oily_17]

Yeah Hayder is right, up your voltage and check it on full load with CPU-Z.

I thought you had 1.4V real and not in the bios.

 

[SteveJK]

Isn't that software takes -0,5V on readings? Oh... so I have to upper the voltages... I'll get some more benchmarks..

 

[oily_17]

Not that I have heard of..., but you can always compare with other software and you will get a more realistic idea of what your Vcore is at load.

Compare HWMonitor and CPU-Z and see if you get the same readings.

 

[SteveJK]

Same readings... New drop:

1.28 V - 1.36 V


EDIT:

Here an OCCT Linpack 5min test:



Notice that VCore drops from 1.36 to 1.28 Volts when stressed...
In stock values (1.3 V @ 2.4 GHz) it drops from 1.25 to 1.20, sometimes 1.18 if I'm not wrong. I think it's ok

 

[SteveJK]

Crashed when playing Ghostbusters... trying 1.41875 V

 

[oily_17]

It was cool on 1.4 V... 15 simple passes of IBT ok.

I've started a Company of Heroes match... 20 mins later... >RESET!!<

oh come on...

I'm now @ 1.4125 V... let's see...

Does your PC only restart when you are playing a game ?

You may need to take a look at your GPU and what temps it is hitting.

When you say the PC 'resets' does it blue screen, freeze or just restart ?

 

[Hayder_Master]

1.4 Vcore should get you to 3.2 no problems, have you tried to raise the MCH voltage any.

sometimes need high voltage with high VID cpu , for me i need 1.45v in bios stable on 1.40v cpu-z read but sure i don't have Vdrop with my mobo

Yeah Hayder is right, up your voltage and check it on full load with CPU-Z.

I thought you had 1.4V real and not in the bios.

thanx my friend , as you know only few P45 mobo's have no Vdrop

Same readings... New drop:

1.28 V - 1.36 V

as i told to you so 1.28v is your voltage for overclock and this is low voltage to hit 3.2 with your q6600 , i say your q6600 cuz your q6600 have 3.0VID which we can put this with high VID range and that's mean you need more voltage
there is three solution for you
1- increase voltage which is most people don't like cuz it is some kind of risky.
2- hardware voltage mode and this is more risky than above and very difficult.
3- buy new P45 with no Vdrop and this mean waste money for overclocking.
and this the chose back to you

Yeah, only playing games. My GPU is totally fresh, 53°C max temp on stress...

My pc just restarts. Never seen a bsod.

I'm highering the voltage 1 step per time. But I'm not gonna pass 1.45 V. The problem is the mobo, CPU works fine, no errors in Prime 95 (blend, 2 hours), no errors in IBT (100 cycles, standard). The problem is the drop.

Can you suggest me a P45 mobo with no Vdrops? I just need a mobo with P45, DDR2 support, and 1 PCI-E x16. Obviously, I'm not going to spend 200 Euros (I'm italian).

I've heard about digital phases on CPU, and as I know, the LanParty mobos are with them but they didn't mention 1600 FSB support.

I was looking at DFI LANPARTY BI P45 T2RS Elite (I can't see it on italian e-shops) also the Gigabyte GA-EP45-UD3R. What you think about them?

 

[h3llb3nd4]

the p5q pro/deluxe is a good board

 

[SteveJK]

Nice card... but I just need 1 PCI-E x16

I have an Nvidia card... P45 only support Crossfire... so if I want to use the second PCI-E x16 I have to change the VGA... nah

well you can get a raid card
any way the p5q is a good board for OCing
check out kyle2020's rig

 

[SteveJK]

nice 3.6 GHz... very nice...

But what about the Gigabyte i've mentioned, the GA-EP45-UD3R?

(rev. 1.1)

I not so sure, I'm kinda fanboy of asus mobos

 

[SteveJK]

Heheh, h3llb3nd4: I had the ASUS P5N-D for 1 month... BSODs every day with no OC... I've RMAed it and sold out.

I know that Asus MADE good motherboards... but now, I'm not so confident...



P.s. reset while writing reply... now trying 1.425 V

you never know man!
you should try the P5Q tho...
make a poll!

 

[SteveJK]

Yeah, of course Asus are good, I saw the 3.6 GHz on the P5Q Pro... but you know, it's just a bad feeling about it

New info:

BIOS = 1.425 V
CPUZ Min = 1.296 V
CPUZ Max = 1.360 V

Drop reduced!

 

[SteveJK]

All stock settings (266x9 Vcore 1.3 and so on)

CPU Vcore = 1.18V min - 1.25V max

Amazing...

 

[phanbuey]

have you tried disabling EIST and all windows power features?

 

[SteveJK]

EIST, C1E, Thermal... all disabled...

 

[SteveJK]

What about an DFI Lanparty P45 motherboard? It has digital phases, I think it's more stable

 

[SteveJK]

Can it be the execute disable bit option that resets pc? I'm trying now without it.

 

[SteveJK]

Execute disable bit enabled... but:

Performance = Turbo

Multi = 8x
FSB = 400 MHz
CPU V = 1.55 V
CPU VID = 1.3 V

(CPU-Z goes from 1.488 to 1.42 V)
DDR = 800 MHz
Timings = 4-4-4-12
DDR V = 2.1 V

PCI-E = 101 MHz
FSB V = Normal
MCH V = Normal

3Dmark06 done with no issues... I think I'm going crazy
