I could hit 4 with that on the i7 930. Oh well. It just means next go around I'll get a good clocker like my old E8400 that could do 4.5Ghz on air. Love that chip...now that was fun!

This was back when they'd put the VID right on the box. So I could go to Fry's, order 10 and pick the best one when they brought them all out.

I'm pretty new to overclocking so all the information is a bit overwhelming.
One thing that confuses me..is RAM...the speed & timings of it as well...anyway hopefully..after some more careful reading and a bit of testing I'll be able to reach my goal .

I'll definitely post back here and give an update on my progress!
What ram do you have? What are your voltages at?
post #1293 of 1922
Sorry for the late reply fellas, didn't think I would get such quick replies, I really appreciate all the help I can get!

Currently stable at 3.8Ghz

Any suggestions on the best approach to reaching 4.0 or maybe some tweaking in the settings I have so far?

--------------------------------------------------------------------------

The ram settings I am really unfamiliar with. I haven't had a chance to actually read about how to set timings etc. And I will be doing that tonight

I believe my ram specs should be at 9-9-9-24-2N @1.5v but I don't think they are and the settings are left in Auto.

Ram: G.SKILL Ripjaws Series 8GB 1333

I'm also picking up a pair of G Skill Sniper 8GB 2x4 1600 just cause they were on sale haha Not sure if these would make a marginal difference in performance but I don't know what came to me when I chose 1333 over 1600

Thanks for all the patience, I didn't realize how overclocking can be so addicting

I think I am gonna have to read the whole thread again. I'm tempted to have this clocked to 3 or 4ghz but bios bis so much a little complicated for me. Too used to 775 socket bios. My own trial and error but I gotta learn anyways. What is the most stable overclock without risking anything? Especially on auto settings? Or do I have to overclock this manually. What exactly does docp do? I'm on xmp settings and everything is auto for a long long time. Maybe I should leave it alone and never overclock it? Also I never did bios updates cuz I never never had one problem with mny system at all. Lol.

Hey onlsaught, leave it as is for now, try to lower core voltage and get it stable(if you reach unstable, then bump it up and test again), nice imc volts, but I'm not sure if that'll hold out. I would get those snipers, they're nice, you can run 3.8-4ghz more easily and stable. Let me know if you're getting them, then we can get your cpu to sweet settings.

Hey 78@pwnt4lif3, personally I would go through the little bit of learning and effort for more clock. Could you give me the results of cpuz? Need to know what volts your mb decided to give your cpu and ram, and what your timings are at. Manually is the best way, auto could decide wrong, manual isn't complicated in anyway.

Ram Timings
Just a few suggestions

Enable Xtreme Phase Full Power

Set CPU Differential Amplitude - 800mV

Drop CPU PLL Voltage to 1.8

Disable Load-Line Cal - This will cause you to have more vdroop so you'll have to raise the vcore setting to adjust for it.

Disable PCIE Spread Spec

Looks like you have the memory running on the 2:8 multi (~1450MHz) That's a nice overclock for that RAM and auto timings has loosened them up for you to be able to do it. I suggest dropping to 2:6 on the memory multiplier to take some of the tension off the RAM while you work on getting the CPU side of the overclock stable. Then especially once you get the new RAM you won't have too much trouble raising the memory speed back up afterwards. *** note here it's common for Asus BIOS not to actually show the memory multi options (2:6, 2:8, 2:10 ) but rather show the frequencies available per multiplier as options. ****

From there check for stablity on the 181 baseclock you are already at and adjust CPU/IMC voltage accordingly. Then raise the baseclock a little at a time while keeping it stable. Some quick runs of IBT standard are good enough for testing on your way up. Then once you hit 191 do a full run of stability testing (whatever suits your fancy but I'd suggest 20 runs of IBT Max then 12+ hours of Pime 95 Blend. Once you get that then raise the memory speed and set the timings adjusting as necessary to keep it stable.


On setting the timings when you see the specs at 9-9-9-24-2N as listed. The first four numbers ( 9-9-9-24) are the first four numbers on you DRAM Timing Control screen

CAS# Latency -currently 9
RAS# to CAS# Delay - currently 10
RAS# PRE Time - currently 10
RAS# ACT Time - currently 27

The last number (2N) is Timing Mode (a little further down)- currently 1N

In CPU-Z those same numbers are listed as

CAS#Latency -9.0clocks
RAS# to CAS# Delay - 10 clocks
RAS# Precharge - 10 clocks
Cycle Time - 27 Clocks
Command Rate 1T

Wouldn't it be nice if everybody called the same settings the same name lol.

Also as you probably already know but I'll mention it just in case the DRAM Frequency (725.3MHz) listed in CPU-Z is half of the (1450.
6MHz) effective rate that you will customarily see it at in BIOS etc.

3.6-3.8 is usually a nice safe overclock to start with. Don't leave it in auto settings though.

D.O.C.P (DRAM Over Clock Profile) - It's auto overclock profiles designed to bring memory speeds up to common overclocked speeds 1333, 1600 etc.. Very similar to xmp.

Update to latest BIOS and overclock it manually. Or set everything to optimized default settings and forget about it. Up to you, I just suggest if you want the CPU or memory overclocked do it yourself rather than relying on any of the auto overclock features.

Interesting. I will try these as they are usually opposite when I oc.

So I left Prime95 last night and woke up to a restarted PC
So then I made the changes ~sizzle~ suggested and I got BSOD's just after booting up the OS.

After a few tweaks again, I'm currently at these stable settings.

CPU Ratio Setting [21]
Intel SpeedStep [Disabled]
Xtreme Phase Full Power Mode [Auto] -> Enabled
BLCK Freq [181]
PCIE Freq [100]
DRAM Freq [1448Hmz] ->1086
QPI Freq [Auto]

CPU Differential Amplitude [Auto] - I left this on auto still. Is 800mV ok with all these minor changes?
CPU Clock Skew [Auto] - I also left this on auto, not sure if this even plays a part in OCing. Please advise *hehe*

CPU Voltage [1.3] -> 1.35
IMC Voltage [1.2] -> 1.3
DRAM Voltage [1.65] -> 1.5
CPU PLL Voltage [1.9]
PCH Voltage [Auto] -> 1.05

Load-Line Cal [Auto] -> Disabled
CPU Spread Spec [Disabled]
PCIE Spread Spec [Auto] -> Disabled

Temp: 58 Degrees Celsius (Max)

20 minutes with Prime95 and still stable.
Maybe I'll run IBT right after for another 20 minutes..

In regards to ram, can I just leave the timings on auto for now and maybe play around with them when I get the pair of snipers into my PC?

So the lower the RAM freq the tighter the timings..vice versa?

Do i really need to update bios? I never had problems with this system at all. Is it needed? Especially for preparing to overclock. Well i do know it's probably needed because they fix it to make things stable i believe. I have overclocked so many times but i'm still not familiar with the new processor bios because they look so much different is why.
post #1300 of 1922
Check out the motherboards BIOS download page. Usually they list the fixes. Also, check for user forums to see how others like that particular BIOS.

For me, I had some issues with power management features like C1E not working past 160 bclk. A BIOS update later on fixed the issue completely.
