TPU's Core i7 Overclocking and Feedback

[kid41212003]

I just re-checked my bios.

There is purple zone 2v+, and red zone 2.3v+, and this is memory voltage.

Beside this, there is nothing else is mark with color. Even CPU voltage, it can go up to 1.9v, and it's all white...

I got the Windows to boot 6 time into Windows with CPU PLL 2.0v and 2.1v (didn't try more than 6 time), but not with 1.9v ->1.98, or 2.2v+

Sorry for the double post.

This is the reason why, in 3DMark 2006 SM 2.0 test, the score is lower when you have HT enable. I think the SM 2.0 only support up to 2 or 4 threads, and It thinks the first core, and the second viture core is physical core, and left the true core out.

Few of my games have the same behavior, especially in Company Of Heroes, I got x2 FPS when I have HT disable.

So then, all you would have to do is manually set your affinity to overcome it?

I'm not sure which one is the true core. Beside I still can't run 4 cores over 4GHz with HT enable, so I'm sticking with 4.1GHz and HT disable for now.
I'm so sick of all the crashing, and hitting del button in the past few days, gonna do some gaming benchmarks.

alright ladies, this is what i'm at now, anything higher it crashes. You think it crashes because the CPU needs more voltage, or coiuld it be anything else in the BIOS?

Pretty much everything is on auto except for the vcore and the bclk. the ram is at 1.6v, and the timings are set to spd, but manually. Suggestions, advise???

 

[Fitseries3]

set ram timings to 9-9-9-24.

1.65v-1.7v vram

3.6ghz needs about 1.34v-1.38v

you can try disabling HT.

 

[Binge]

Yeah if you don't want to volt then go for HT off. Right now I'm pushing 1.4v for 4.2GHz bench/stress test stable with HT on.

4.2GHz!?

 

[Fitseries3]

you act like thats alot. up to 4.5ghz is typical with the 920.

Are you using the 2GB Corsair XMS DDR3 1333 kit shown in your system specs? If so, then are you sure they will run DDR3-1400 9-9-9-24-1T? You might try a lower memory multiplier to see if it's the memory holding you back.

I believe the current version is 2.90 RC2

Thanks fit.but I cant do nothing until my waterblock doesn't get here. I am ordering tonight from Performance PCS, Apogee GTZ.


For now i'm fine at 3.5 GHz

I was actually thinking about that now, I'll try that before trying to add any voltage to anything. Thanks. and good looking out.

4.2GHz is a lot (fast)... Tut. I'd be happy at 4.2GHz.

yeah, if I get stuck at 4.2 GHz for whatever reason, i'll be happy! However the if I can go higher, why not

With my cooling, I should hit 4.2GHz no problems then

 

[Fitseries3]

actually its a PITA to get 4.2ghz to run 24/7. it also requires a damn good cooling setup.

 

[Fitseries3]

this guy said it pretty much flat out...

A NOTE FOR YOU GUYS THINKING OF GOING WATER ON I7....

2 pa120.3's, 6 scythe ultra kaze 133cfm fans, 1 iwaki rd30, gtz and nb-max can keep my i7 running at 4.2ghz all day BUT the water is 90f + and the rads are blowing HOT HOT HOT air.

the i7 does put of alot of heat.

hey fit what are you using to cool your CPU right now and what temps are you getting?

 

[Fitseries3]

look at my last post.

yikes, that scares me dude!!!

 

[kid41212003]

@Chicken Patty, If your system won't post, try to change the ram timing tRC to 35 for all channels.
The stupid thing is, I could prime95 196baseblock x21, ~4100MHz for 12 hours, HT off, but I couldn't get it to run prime95 200x21, 4200MHz for 30 seconds.

 

[Fitseries3]

yup.

i benched 4.3ghz ONE TIME. i reboot the computer and it would not even post. i had to reset the bios.

i have a SUPER cooling setup on the way and soon a new cpu(possibly)

 

[kid41212003]

What you gonna do with your old WC setup?

 

[Fitseries3]

selling it. its in my FS thread. only selling my rads though.

Let me ask you, and well to everybody here as well, i'm new to DDR3 RAM, my RAM runs at a Command Rate of 1T, is this right? Usually I know DDR2 runs at 2T for most RAM
