I can tell you're gonna have a lot of fun with that chip duder.

I do hope you're gonna be testing it out under your Kayl SS, that's a chip that will really benefit from the cold.

Yeah, hurry up and make it cold eva

Yeah was hoping to have some fun but I might have motherboard/bios incompatibility issues heh

Looks like the D975XBX Bad Axe rev304 board might not be fully working with Intel Core 2 Quad Q6600 cpu. I ran Systool quad 16M Pi to test clocks with clockgen and from bios and managed

vFSB = default
vMCH = 1.628v
vDimm = 2.05v

- 2900Mhz at 1.242v (1.275v bios)
- 3003mhz at 1.277v (1.315v bios)
- 3060Mhz at 1.312v (1.35v bios)
- 3109Mhz is where trouble starts:
* 1.359v (1.4v in bios) = rebooted immediately in Systool quad 16M Pi tests.
* 1.359v vcore and raised vFSB to 1.395v = rebooted at 13% mark for Systool quad 16M Pi tests
* 1.406v (1.45v bios) with vFSB 1.395v = PASSED Systool quad 16M Pi tests.
* 1.453v (1.50v bios) with vFSB 1.395v = rebooted after 8-13% in Systool quad 16M Pi tests
* 1.476v (1.525v bios) with vFSB 1.395v = hangs at boot time just before windows logo

Raising vMCH to 1.685v from 1.628v allowed me to pass at
* 1.359v (1.4v bios vcore) + vFSB 1.395v + vMCH 1.685v = PASSED Systool quad 16M Pi tests (can even loop the test without problems).

Clockgen'ing from 3109Mhz to 3150-3200Mhz resulted in Systool quad 16M Pi test rebooting immediately regardless of vcore up to 1.453v. Similar, if i set in bios greater than +30% FSB adjustable i.e. +33% will result in hang just before windows logo loads.

For those that recall, originally D975XBX Bad Axe board came with max adjustable FSB in percentage terms at +30%. Then later bios allowed +50% max FSB. It seems with Q6600 cpu, i'm only getting stable FSB clock at +30% max so far with 1441 bios. Might need to try earlier bioses as well Semi Official Intel 975XBX Badaxe motherboard info and see if it helps.

Hope it's the board/BIOS and not the cpu as this Q6600 was pretested by the seller to 3600Mhz 9x400fsb quad prime stable at 1.45v vcore on air on Asus P5B Deluxe and Asus P5W64 WS Pro motherboards

Update: Looks like Kentsfield might have a low FSB limit on D975XBX Bad Axe motherboard, Shamino only managed max 356FSB with QX6700 on D975XBX Bad Axe http://sg.vr-zone.com/?i=4098&s=7.

There's you answer eva

Or you could just wait for a distie to give you a BX2 or 680i

dinos22

nice going so far

maybe a different mobo is in order heheh

Nice George

Are you going to buy an Anus P5B Dlx or try it in the P5W DH or ???????, I've lost count a long time ago how many 'kin boards you have now
