Q6600 being a pain...

[Jayws]

So I posted my specs in the Q6600 thread and it seems that people are having significantly better results than me. I don't know if I'm just not tuning something right or if it's a bad chip but here's what I've got right now:

3.2ghz
356 x 9
Vcore:1.3875 / 1.360 / 1.320 (Bios/Idle/Load)
Idle Temp (°C): 35
Load Temp (°C): 50
RAM (Size/Speed/Timing): 2 x 1GB / DDR2 890mhz / 4-4-4-15 2T
MOBO: Abit IP35-E
PSU: Corsair 550VX

I've been seeing people getting 3.2 on 1.3Vcore... I also can't for the life of me get to 3.4ghz even when I go up to 1.4250 Vcore (more than that seems absurdly high to me). I've tried jacking up the MCH as high as 1.53, the VTT as high as 1.3350 w/ GTLREF @ 67% (max), I'm just not sure what's going on here...

run your RAM 1:1 ratio, put the FSB to 378 (x 9) or so, I think that's 3.4Ghz CPU. set cpu vcore 1.42 bios, vtt 1.235 or something close, MCH 1.49. see where that gets you.

*sigh* I'm fairly sure I've tried something similar to this but I didn't record every test I did today (which I am now regretting)... I'll go give this a shot and let you know if I can get more than a minute out of it while benching.

Try 420x8=3360MHz using a 333/667 (1:1) strap setting, which will run your RAM at 840MHz. Set your Vcore to 1.4v, temporarily set primary RAM timings to 5-5-5-15-2T and 2.1v, MCH to 1.5v, CPU VTT to 1.35v, and CPU / NB GTL's to 67%.

 

[Jayws]

@Terran: Nope. It posts, boots, loads everything but when I loaded up Prime it reset. I tried bumping the MCH again from 1.49 to 1.53, still no luck.

 

[terran2k]

my cpu seems more stable with a low GTLREF, 61.5 and 63%. loosen up the timings on your RAM too.

 

[Jayws]

@redduc: no dice, no post, no boot with small increases
@Terran: I'll give a lower GTL a shot

 

[Jayws]

still no luck

 

[terran2k]

whats ur cpu vid?

 

[DocClock aka MadClocker]

Could it be the ram? what volts?

 

[Jayws]

I don't think it's the ram... I've run it very stable at the settings in my OP. It's been set at 2.1v.

edit: coretemp reports 1.3250 as the VID

 

[terran2k]

try 1.45v bios vcore. you have room to play with as long as your temps are below 70C.

 

[Jayws]

378 x 9 @ 1.4450 bios seems to work fine. I'm gonna prime it for about 6-8 hours and see what happens but it boots and stays stable for 10 minutes which is more than i can say for the other stuff. This still bring me back to my question though, which is why does my cpu seem to need so much voltage to get the same results as others? Is it just a bad VID? Could it also just be vdroop? I'm hitting 1.376 - 1.384 under load and 1.408 idle now. I wanted to try and stay as close to or under 1.4 as possible.

edit: Bah, fails after 3 minutes. I'm gonna give the MCH some more juice... wth

Change the following...

EXTERNAL CLOCK............400
MULTIPLIER FACTOR........x 8

CPU CORE VOLTAGE.........1.325
CPU VTT 1.2V VOLTAGE... 1.2
MCH 1.25V VOLTAGE........1.25
ICHIO 1.5V VOLTAGE........1.5
REFRESH CYCLE TIME (tRFC)... 48-52, and leave all other RAM sub-timings on AUTO (except for the 4 primary timings; 4-4-4-15 and 2T Command Rate)

... then run Memtest86+:

http://www.memtest.org/

If Memtest passes, and you can make it to the Desktop, run OCCT...

But redduc900, that's only 3.2 Ghz

Just dump more volts in the damn thing!

I can't even post at those settings...

edit: it boots with 1.3450

 

[Jayws]

OCCT failed in 7 minutes with error code 1, I'm gonna go get something to eat and let memtest run for about an hour

 

[Jayws]

memtest passed all tests

I can't get it to consistently post/boot all the way up to 1.4vcore on the settings above...
