It begins...

Just waiting for 3dMark 06 to finish downloading then up to 1.5V, see what happens!

By the way, Core Temp 0.94 is reporting Core 0 @ 27C and Core 1 @ 28C. Room temp is 18.5C (cold!)

Speedfan 4.31 is reporting 36C and 20C for CPU and System.

What should I believe?

Hrmph...

Seems most I can get outta this is what I posted before. 1.525 isn't even helping on the CPU...

sprognak · 3 Dec 2006 at 16:59

Vcore now at 1.3875 or around there. Seems stable at 405FSB, 8x Multi, 4:5 RAM (1010MHz) @ 4-4-4-12.

G(MCH) @ +.1
FSB @ +.1
PCIE @ +0, 105MHz

With CPU up to 1.525, FSB up to +.3, G(MCH) up to +.3, my FSB wall seems to be 430MHz (Even with 7x multi).

Temps are below 40C at any of these voltages.

Can't get 9x multi at 400FSB either =(

Drop your RAM back to 1:1 and see if it's any better.

And I'd trust CoreTemp.

sprognak · 3 Dec 2006 at 17:51

Tried that, still caps

sprognak · 3 Dec 2006 at 17:56

What's slightly annoying is the DS4's tendancy to "auto fix" the problem by scaling back the FSB and not waiting for confirmation!

torrentthief · 3 Dec 2006 at 17:57

ds4's generally have a barrier of 485fsb, some a little higher some a little lower.

p.s try different ram slots, the colours DO make a difference, i got 475 with orange slots and 485 with yellow slots.

Got a 9x Multi

Now running at 400FSB x 9 = 3.6GHz.

Had to 1.56875 Vcore it though!!!

sprognak · 3 Dec 2006 at 18:27

Not stable for Orthos. VCore now at 1.58750. Coretemp showing 37C and 39C. Retrying Orthos...

sprognak · 3 Dec 2006 at 18:29

Ok, Orthos doesn't BSOD anymore! But it now bombs out after a couple of seconds. Coretemp rockets to 58/60C during those few seconds, then instantly reverts to 37/38C.

Advice?

Cob · 3 Dec 2006 at 18:29

What's the CPUs stepping?

And have you disabled everything that you don't need in the BIOS, including Legacy USB?

sprognak · 3 Dec 2006 at 18:43

Yes. Stepping 6, Revision B2, CPU was stamped with L629B513 which I believe is Week 29?

Currently I'm on 1.58750 VCore, 2.6GHz, RAM at 4:5 (1000MHz, 4-4-4-12), FSB 400 (Pumped to 1600).

I'm stable to boot up (just), but Orthos reports an error instantly. In the few seconds that takes, temps hit 60C and drop back down (coretemp).

If I lower the multi to 8, keep those voltages and bring the RAM to 2:1, I'm still FSB walled at 430MHz...

sprognak · 3 Dec 2006 at 18:52

I very nervously upped the voltage to 1.6V, but dropped the Multi to 8. It boots and is stable. Orthos takes coretemps to 69C

sprognak · 3 Dec 2006 at 18:53

Eeeeek! 75C. I chickened and aborted Orthos...

Trox · 3 Dec 2006 at 18:53

What cooling are you using on that ?

sprognak · 3 Dec 2006 at 18:58

Scythe Ninja with 1200RPM Silent Scythe fan.

In a V1000 Lian-Li case, it has good cold air from the front and an exhaust 12cm right behind the HSF.

Trox · 3 Dec 2006 at 19:03

dont think i would be pushing it to 1.6v on air cooling though, maybe time for some water

How does the memory perform? How high have you had it on 4 4 4 12?

Gashman · 3 Dec 2006 at 19:06

increase vcore to 1.5v and increase chipset voltage a little if you can, with my X2 it wouldn't go above 2.55Ghz until i increased chipset voltage

No offence, but please read the thread. I've just been running on 1.6V...

so 75C is ok for coretemp during Orthos????

Makes me unhappy to be honest.

Edit, memory is fine at 1GHz 4-4-4-12
