Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

[chaotic646]

Thanks for the replies. I was going to get two sticks of 512MB but two 1Gb sticks are only $13 more so it would be dumb not to even if XP can only handle 4GB. DDR2 memory is a LOT cheaper even since last year when I built my current rig. Must be because DDR3 is out now.

Hi,

I am new on this forum, and i am french. I hope you will understand me.

It is not my first quad, not my first oc, not my first memory timings settings, but it is my first Intel BadAxe2 (rev 507, bios=2792, 2797 or 2802, test with 2333 too). My job is assemblying PC for particular customers and optimize mine (photograph).

The System:
Quad Q6600 G0 @ 9x345, 9x346 but not 9x350, Crucial Ballistic Tracer (5.5.5.15, 2.16v and +, or 4.4.4.12@2.24v or 2.28, 2.32v) 266/533 or 266/667 or 333/667, with ratio 1:1 or 4:5. I change each parameter one by one. Antec P182-Seasonic II 550 Energy II

I have another quad QX6700, B3, hot on Gigabyte P35-DQ6@12x284, Crucial 4.4.3.12, any issue with it, in a beautiful Lian-Li v2000 (very large) Seasonic 600.

The cooling is by air with Thermalrigth Ultra 120 eXtreme with Artic 12025pwm or Noctua NH-12F. I prefer Artic because t° is -8° than Noctua on the same system.

My issue:

I read about the first 70 pages and i didn't found the beginning of an answer.

The Bad Axe 2 don't "consider" the voltage i set in Bios (maintenance or normal bios). I set 1.35v or 1.40v or more but the voltage is always is 1.2750 or less with speedfan, Everest or Intel DU.

C1E, EIST, Watchdog, etc are disabled. But even enable, i see the same thing.

I can set the voltage i want in bios (maintenance or normal bios). I see it, i shutdown the PC, i unplug power, i wait for green light off and i reboot, i see the good voltage in bios... but...

Under windows, i run OCCT for test 4 cores @100% during 30' and i can see the voltage idle = 1.17/1.16 (like vid) and full @1.24/1.25.

I can Never see my own voltage i set, as 1.40 or more.

I thought that my CPU did'nt need this voltage so i could'nt see this voltage.

My pc is very stable @3146MHz... but i think that the frequence of Q6600 could be set higher. Over, the cpu voltage don't go high..



Is the issue know?

Is the issue from my BadAxe2 or my Quad ?

Do you think i have to test my other quad on it ? or exchange QX6700 on BadAxe2 and Q6600 on P35-DQ6.

I test 2795, 2797 and 2802. I test too the old 2333 bios. I reset the bios each time i change....

Very strange issue...

Thanks for your explanation and the big array of frequency memory (usefull for the beginning).
