Ok,

CPU Ref and MCH Ref Adjustments:
Back your vTerm down to 1.2v
Manually set your CPU Term to .76v
Manually set your MCH Ref to .74v
Set your vTerm back to 1.3v.
CPU and MCH Refs will then adjust for the FSB voltage references.

I don't know squat about the q9xxx's, so I won't comment on your vCore. But I don't think you should need more than 1.28v for vTerm (CPU Term) and MCH Core. dennyb can probably correct me on the Term, but the MCH Core should be the same for quads as it is for duals.

Generally, you don't need to raise your PLL till you get over 500MHz FSB. You shouldn't need to raise your I/O stuff till you pass 450MHz or even 500MHz either.

As for the memory, you have 8GB, so your timings need to be a little looser than if you had less. Set them Loose then, once you're Stable, use Memset to gently lower your timings. Eventually your Desktop will freeze, then you will know you went too low. Also, when using Memset or ET6 to make a change DON'T HIT SAVE. I don't know about anyone else, but Save crashes my system in both apps. Use Apply. Oh, did you know you can use ET6 for this? Once you are Stable, then you can use ET6 to gently lower voltages, like I described for Memset. It's a good way to find the lowest Stable settings for Voltages and Timings.
Any one else have any input?

I agree--a good 4890 pretty much spanks most games you throw at it, especially if it's oc'ed.
Good thanks. You done with training?

Edit: Looks good Grish, I have never had to change volts on the SB.

Hello mate, I always start all games with all settings maxed out. And if i needed i would lower them from there!
But as long as I'm getting 60fps I'm happy

@ copyright --here are the setting I suggested from a few pages back
445x9
LLC=enabled
V-core=1.300
Term=1.260
PLL= normal
CPU Ref=.83
MCH Core=1.26/1.28 (mine is 1.24 but you are running 8 Gb Ram so your controller will require a little more voltage)
MCH Ref=.80
These settings are pretty close to what Grish reccomends
Follow Grish's lead on advance timing control--I don't know squat about those settings,so I have been using normal

Copyright--what does coretemp say your vid is?
The tjmax for Q9xxx chips is 100

Hey crash--good to see you back

Yeah. I've been back at work all this week. We're both happy and sad. Happy I'm back at work (they laid off a few guys while I was gone) but kinda sad because I now hate my job, lol.

Well i struggle for 60. My 4890 is so slow it is beyond belief. Slowest GPU i have ever had. I can't deal with this PC any more.

ok what about all the ESIT C1E stuff? Also my CPU VID in CPUZ says 1.25V. Also whats best for stressing? I have always ran Prime 95

Off with C1E
Off with EIST
Off with your head for getting such a low vid chip--Ok you can keep your head since your edit cleared that up

Wait coretemp not CPUZ
you need to have C1E and EIST off then look in coretemp to see the VID



I test P95 sm fft 8 to 12 hrs then the same for blend. Once you get stable in sm fft ,the v-core /term part of the overclock is solid. The blend will tell you about the MCH part

EIST and C1E are entirely up to you. But, turn them off while finding Stability. Then, if you want, re-enable them after your are Stable. They work insanely fast, so you won't notice the difference in applications, although you will notice slower Boot times.

Coretemp and RealTemp will show you your VID. CPUz shows your vDroop/Drop.

As for stressing, that is a huge debate. If you can get 24 hours Large Ftts, then I call it stable. But dennyb is different and uses different standards, which, I am sure, he is typing in right now. Some people say that if you can make 5 Linpack passes at All Memory setting, there is nothing more stable. Some people use IBT, others use Occt....

I have started using a little of all of them. An hour of Occt Small, 3 Linpack All Memory passes, a few hours of Prime Blend...
