Decided to give OC'ing this chip another go. Don't like sitting at 3.4GHz lol. (3.7/3.65 Wasn't stable).

I have some bios shots to upload later.

Here's my story.

1 week ago I noticed that after going above 3600MHz, SPI would start failing. Not BSOD'ing just crashing. Which I thought was odd, no other CPU that I have OC'ed too far has done that.

Been fiddling around in the bios now, My MCH/ICH Temps are fine. Stuck the MCH to 1.42v, cool to the touch.

Theres a few things I need to sort out. If I try to boot at...

400x9
LLC Enabled
1.45v
1.42v MCH
1.2V ICH
1.9V DIMM

All others 'Normal' *System Will NOT Boot* BIOS Resets.

Something isn't getting enough voltage at the 'Normal setting' Which is probably CPU or MCH.

I'll have to sort that out by the process of Elimination.

EDIT:

SPI Still crashes, 8 minutes in.. Prime Core 1 errors out in the first few seconds...

I can't remember

I'll check next time I see the CPU.

It was stable enough to run 3D benchmarks, games and I ran prime for a few min but I stopped cause it was boring

any chance of running 32m Pi or any of the 3D MARKS at 4400mhz-4500mhz? I see you got 4300mhz on air but only 4545mhz on PHASE?

What type of phase unit are you using? I'd have expected a little more than 200mhz+ from switching to phase from air.

**fatguy1992** · 02-16-2009, 02:34 AM

The max I got on air was 4.1GHz.

Next time I start my phase change PC (benching PC) i'll run SP 32M and I ran 3D Mark 03, but my score is bugged

and it was lower then 3.6GHz

I haven't run 06 yet, atm i'm just trying to get high GHz. Once i'v done that i'll turn my attention to doing some more benchmarking

ahh sorry , my mistake.....as usual

look forward to seeing your 32m soon. I can do 12:25secs at 4100mhz and would like to see how much you can shave off that with a 4300mhz+ Q6600

**Bootup05** · 02-16-2009, 06:20 AM

Thanks fatguy1992!

I'm gonna give that a shot now. I'll report back, probably within the hour after Prime fails again

.. Why is KELL5 Banned.

**Bootup05** · 02-16-2009, 06:40 AM

Alright I've just tried them exact settings. Boots OK. SPI Still stops after a few seconds. Worker 1.

I guess I have a bad core? Well one that doesn't like OC .

What RAM are you using, cause some RAM can't do 1066MHz on 2.0v.

With my E8500 with air cooling I had a similar problem, one core would always fail no matter what I did. Then I tested it with my phase change and it was fine. I'm not saying you should go and get phase change tho.

BTW i don't know why KELL5 is banned, most have done something wrong

**Bootup05** · 02-16-2009, 05:00 PM

I was booting 1:2, My ram won't do 1066

I'd hazard a guess I'd be stable if my chip was that much cooler, But I ain't going phaze change just for this chip

I'm probably going to pick up a different chip / new ram some time soon.

I'll see how high I can boot FSB wise within the next day just to get a judgement of how capable my board is. Will have to watch the RAM though.

**fatguy1992** · 02-16-2009, 09:33 PM

I got my Phase Change for my awesome Q6600, also i'v heard the new Q6600 can't even get above 3.0GHz.

**Anubis161** · 02-17-2009, 12:26 AM

My first OC attempt
Stable for now @ 3.4Ghz - Vcore 1,3250
gonna get some new memory sticks thou
Dram @907mhz 5-5-5-18

Using a Cooler Master V8 for cooling:

Both, heatsink and cpu still un-lapped

**fatguy1992** · 02-17-2009, 12:38 AM

to XS

Not a bad overclock there

What VTT and PLL volts are you using?

Also change the Tj. Max to 95C instead of 100C

VTT and PLL are on auto, didn't touch anything else yet, just the

ty ram freq. set to 907mhz and timings to 5-5-5-18..
cuz i'm rather new to overclocking, and don't want to burn anything on the first attempt :P

set tjmax to 95°c.. but saw different readings, some said tjmax is 90c, some 95c, some 100c... so what is tjmax for a q6600 g0? I know it should be 90°c regarding Intel, but that's just LOL

**fatguy1992** · 02-17-2009, 11:51 AM

Your more likely to burn out your chip with auto setting. Set the PLL to 1.5v and the VTT to 1.3v.

Well I always use 95C TJ. Max, cause 90C is way to low for me.

Very nice work there Bootup05

Quite a bit of vcore tho.

**Bootup05** · 02-17-2009, 07:10 PM

Yeah, 1.66v @ BIOS. Ain't measured VCORE with DMM yet.

Only ran for 2 mins, vista took an age to boot, tense moment!

**wyemarn** · 02-22-2009, 07:56 PM

I just got myself a L744 replacing my lousy L804. The VID is 1.225V. Currently I doing 3.3Ghz(8*412) with 1.225V set in BIOS. Under load, the vcore is 1.216V under Everest reading. Temp are around 65C.

That L804 can do 3.2Ghz (8*400) with 1.30625V in BIOS and produce roughly the same temp. Im not sure why the temp for my L744 is high although the Vcore is low.

Btw, may I know what is the accurate TJ Max for Q6600 G0? Currently it's set at 100. If I set it to 90C, my idle and load temp will decrease by 10C and that means I can push it further.

**fatguy1992** · 02-22-2009, 08:42 PM

Intel says the Tj. Max is 90C, but most people (such as myself) use 95C.

**Loser777** · 02-23-2009, 12:53 AM

Lower VID chips tend to have higher temperatures... going from a 1.3125v to two 1.2125s... I know the difference firsthand.

**fatguy1992** · 02-23-2009, 12:57 AM

That doesn't make sense?

Or am i missing something?

**dan7777** · 02-23-2009, 12:58 AM

lower vid mean lower temps dosnt it ?

??????????????????????????????

Can this please be explained and shown with some proof?
