TPU's Core i7 Overclocking and Feedback

[DrPepper]

Hey guys finally got my i7 up and running and decided to do some overclocking. I wanted to start off with my memory and see how fast I could get it before overclocking my cpu. So far I stopped at 1866mhz at 9-9-9-24 2T. I left voltage at auto because I don't know the safe voltage range for DDR3. What would be the best timings to reach 2133mhz.

i never fuck with memory so I won't answer that. As far as voltage though, you can go upwards of 1.7v as long as it is within .5v of your qpi/dram voltage. Example below

DRAM voltage: 1.5v
Qpi DRAM: min. 1.0v, max 2.0v

Understand?

1.3v - 2.2v is SAFE.

typical is 1.65-1.8

Yeah I understand that now.

Right, I was under the assumption that over 1.6v was unsafe because I get a big red warning when I set the voltage any higher than that.

mine is green, but it's still a warning. Dont worry you'll be fine. Don't go crazy on that + key on your keyboard now

No promises

OH NOES!!!

Going with memory first will make things more complicated.

Start with CPU first will make things easier. I'm sure you are aware that with core i7, higher memory speed = more stresses on the CPU.

What's wrong with doing things backwards

I agree partially, the other is lazy noobs

depends which way you look at them, but I rather not have this discussion in public.

yeah yeah.

anywho....

anyone else been watching the gulftown?

Never knew that.

Can't get 2133mhz anyway no matter the voltage. Next step is oc'ing the cpu I reckon 3.6ghz before heat becomes an issue.

what bios u using?

I need to check - CPU-z says 4/17/09.

Its not just with the classified. With my Asus, that's how I can tell how close I am.

I've always ran it till the numbers have less than a .05 variance between them. Sure I could run on less, but I've found that if I let it go long enough it will eventually error out. It can take 100+ passes some times. What can pass 25x will show low "weird" numbers when vvt is on the edge of bsod. Normal for 4ghz and 1600 ram 2x for uncore is about 52gflops for me. If the vvt is low it will drop into the high 40s even though it can pass sometimes 25 times.

Question, is it normal to need very little volts to run higher uncore as long as it is 2x ram and not more?

I've found that I can run 1.25v vvt for 1600 ram and 3200 uncore. If I bump uncore to say 3600 and leave memory, then I need about another .1v vvt for stability with no other multi or timing changes (except those changed by auto for higher uncore).

Guys, help over here please, thank you

Hi guys

Can you help me?

I have an Oc stable, 4.0 no Ht with Rampage II Extreme, but i need to use a lot of vcore to get it, 1,318, and i have a D0

I just tried everything, increase cpu pll, , qpi/dram...... but no sucess, i only can be stable with this vcore and without ht, if someone could help me i`ll be very happy:

System specs and bios specs:

Core: i7 920 D0 Batch: 3851A231

Psu: Corsair 1000 Watts

Memory: Corsais Xms3 1600 XMP 9 9 9 24

2x Radeon 5870 Crossfire

Cooler Noctua nh u 12p SE

Now the bios

version 1504 (latest)

Xmp mode Oc

200x20 = 4.0

Vcore 1,318

qpi/dram 1,35

pll - auto

dram voltage 1,65

uclk 3200

Loadline - enabled

c1e - tm - speedstep - disabled

ht - off

ioh - ich - Auto

Thanks again

Thats not that high on vcore for 4.0
Try 1.34 vcore and turn ht back on. If you temps will allow you that much.
