Help getting stable OC - 3930k 4.5ghz

post #1 of 25
Thread Starter 
Hey guys
New to overclocking, and am having trouble getting my 3930k to stay stable at 4.5ghz
As soon as i run Prime 95 (max heat setting) i crash very quickly (minute or so).
Ive tried bumping up voltages and fiddling with stuff. But im unsure as to what setting is the most likely one in need of adjustment.

Here are some Pretty pictures of my Bios

120901211431.png120901211440.png

I am aiming to keep this CPU running below 1.36V for now.


Advice and tips would be great, as well as basic explanations to what important value do. Im still trying to wrap my head around a lot of things, and large guides thus far have gotten me lost trying to remember everything and what it all means.

http://www.overclock.net/t/1189242/sandy-bridge-e-overclocking-guide-walk-through-explanations-and-support-for-all-x79-overclockers

^ Has tons of info for those new to x79.

http://www.overclock.net/t/1186959/rampage-iv-extreme-uefi-guide-for-overclocking

^ Has most of the same UEFI features and can be very helpful.

Unfortunately, I am at work and I can't see your pics. You should be able to hit 4.5 @ 1.36, but there us no guarantee. Some quick suggestions to get you started:

- Run memtest. If you are getting errors, bump your DRAM voltage just slightly higher than rated (0.01v-0.05v). Also, try not to run them too much higher than rated.
- Keep your VCC voltage within 0.5 volts of your DRAM voltage (i.e. DRAM = 1.65v, then VCC should be 1.15-1.2v) Do not go above 1.2v.
- Try raising youR VTT voltage to see if it helps. Do not go above 1.2v.
- Try raising Your PLL Voltage to see is this helps. Do not go above 2.0v (LAST Resort).
- Raise your LLC setting (High - Extreme).
- You may just need more Vcore.
- Use the 100 Bclk strap for 4.5 OC.

I would take a nice long read into those guides, and play with it. It took me a while coming from the P45 platform. Let is know how it went.

Good Luck!

knowing where is temp on full laod can help determine the next step. load temps do matter if you didnt already know this. first thing he needs to do is make sure the timing and the rams are stable at 2133. afterward..its all either more voltage on the cpu or lower the overclock if he wants to stay under 1.36 volts.

morning, Im going to try much of Rmerwede's advice and see how i go.

Temperatures are not an issue. Max temp on blend is 64*C, and Max heat setting on Prime95 gets me 67-68*C MAX. Corsair H100 In Push setup (Exhausting).
Note: Temps are core temps, ambient ranging 20-24*C during the day. These readings are at 4.5Ghz.

I am aiming to keep core temps below 70*C, to allow for warmer ambient in summer as i don't have air conditioning.

I have ram coolers over my ram on my P9x79, so the motherboard is getting plenty of air blowing directly on it around the socket, and the case is very well ventilated. I also have a fan on the back side panel ventilating cool air into the back of the motherboard/socket area.

Edit:
Ram was tested at my 4.2GHz OC. Tested at current 2133Mhz, timing, and voltage. No issues. I did have ram issues previously, due to them not having correct settings in bios. They are currently at what the manufacturer specifies.

Edit 2:
Bumped up Vcore to 1.36V and increased VTT to 1.1V (was on auto). So far so good (1Hour prime). CPU-z Reads 1.368V. May drop Vcore down again slowly till it screws up again and set it to the last good voltage before failing. Cheers for the pointers! Once this setting is stable and the OC is saved i may push on further to see what i can do!

You can go down with VCCSA - recomendation is to keep VTT equal with VCCSA (if it possible). If you can establish stability on 1.1V it will be nice - Some ASUS boards require 1.15V for VCCSA and high clock memory's
UPS i forgot - morning to you to biggrin.gif
