Problem overclock Q6600 + EP45-DS3l

[mcu]

Hi!
Please, help,
just intalled new memory PVS28G6400ELK 4x4Gb

3.2Ghz (8x400 Vcore 1.3500, 5-5-5-15) works fine

want to make 3.4Gz, but 8x425 dint work ok, booting into OS ok,
but when i runjing 4 thread with 100% load it hangs,
Cooler is Big Typhoon VX, temp is around 48-50C.
PCI freq locked to 100

Please, advice additional params for such m/b model.
tanx!

Why not use 8.5x400?
Your memory may be of a problem, it's only DDR-800, and you got a lot of it.
Please post your settings using the template in this post or the one below, and a screen caprure of EasyTune advanced voltage tab.

Holy Ram Batman. With that amount of ram you will most likely need to bump up your MCH voltage a tad. But I would deffinatly go with Chike on this one. run with 400Mhz FSB that will give you a nice 1:1 Ram : FSB Ratio. Find a template and fill it out if you still have trouble. But you will need to raise your MCH voltage a little I think to run that much ram.

Re: Problem overclock Q6600 + EP45-DS3l

The 0.5 steps are done with Fine CPU Clock Ratio, is it disabled?

PCI Express Clock Drive.................: 700 mV suggests you have not began with oprimized defaults, it is suggested to OC with optimized defaults loaded first.

Leaving CPU PLL on auto is not recommended, it overvolt too much when OCed, set it manually to default value for a start.

Could you post EsyTune advanced voltage tab, and MemSet main and spd(click spf) screen captures?
MemSet and other programs may be found in http://forums.tweaktown.com/f69/late...30/#post284762

Re: Problem overclock Q6600 + EP45-DS3l

tanx, yes the Step 0.5 is missing in Menu.

Disabled CPU PLL

Re: Problem overclock Q6600 + EP45-DS3l

.5 is not available for Q6600 CPU's.

Please start over using optimized defaults, not fail safe. Then you should have much more luck.

You may need to try this
CPU Termination…..... 1.200V*.......:1.200 << Set 1.225-1.3
CPU PLL…………………....1.500V*.......: Auto << Set 1.4-1.6

MCH/ICH
MCH Core…………….....1.100V...........: Auto << Set 1.24-1.32, also try less than 1.1 if none of these help

[mcu]

Re: Problem overclock Q6600 + EP45-DS3l

tanx, will try now
What's better to start

9x400 = 3.6
9x378 = 3.4
8x425 = 3.4

Think, FSB:RAM 1:1 is better than 1:1.xx so 800:800 can be good.

[mcu]

Re: Problem overclock Q6600 + EP45-DS3l

Tried :
9x400 = 3.600
Vcore 1.45
Pll 1.550
CPU termination 1.24
MCH Core 1.3
Mem Vcore 1.94

Boot into OS normally, then after minute had PAGE FAULG BSOD error 50.

Now at 8x425 =3.400 with same params.

[Lsdmeasap]

Re: Problem overclock Q6600 + EP45-DS3l

I would try 8x425

Vtt 1.3-1.45

[mcu]

Re: Problem overclock Q6600 + EP45-DS3l

Now working stable 3.4GHz

8*425

Any chance to reach the 3.6 ?
9x400 or 8x350 ?
Or do i need better motherboard?

I need to make calculations 24x7 per some weeks, do it need to stop with 3.4 to prevent my system from damage?

Tanx a lot for helping

[Lsdmeasap]

Re: Problem overclock Q6600 + EP45-DS3l

3.6 may be possible for you, not all will do it though. I would use 450x8 myself, but you can also test 9x400

3.6Ghz may be pushing your CPU a little, but if temps are good and your voltages do not have to go way high your hardware will be fine

Are you folding, or did you mean some other calculations?

[mcu]

Re: Problem overclock Q6600 + EP45-DS3l

Tried 9x400 - same BSOD error, will try the 8x450

Do i need to ajust some memory timings/voltage?

Now at 3.4 Temp is 61-63 with 100% load,

About folding - i making similar calculations, like RSALS

[Lsdmeasap]

Re: Problem overclock Q6600 + EP45-DS3l

What is the BSOD Code again, or did you say?

Please post full settings next time as well, maybe then I can spot something holding you back

[mcu]

Re: Problem overclock Q6600 + EP45-DS3l

The BSOD happens after booting os, at about 1-2 minutes aster logging on.
Will post all params soon, testing now.

About MEM timings, in official datasheet they are:
5-5-5-12
but as i see in MEMSET or SPD:
5-5-5-15 for 400 profile
and
6-5-5-15 for same 400 profile too

maybe it's possible to adjust a little?
for example
4-4-4-12 ?
