Sandy Bridge E Overclocking Guide Walk through, Explanations, and Support for all X79 Overclockers - Page 37

post #361 of 407
Very nice guide thank you very new at over clocking have some Newbie questions.

Rampage 4 Black Edition
I 7 4930K Clocked at 4.5Ghz V Core 1.27v appears to be the sweet spot for 4.5
Air Cooled Noctua NH-D14 Added a pull Fan today lowered the temps 3c on the CPU.
Memory G-Skill 2133 16 Gb Quad Kit. Started the OC by lowering the memory to 1600Mhz bumping the Multi up to 45 all cores. Booted to windows ran P95 for 38 seconds before BSOD.
GPUs 2 x Evga GTX 780s S.C.
Intel 730 Series SSD and 4 x W/Digital Velocity Raptors and 1 x W/Digital B/Caviar 2Tb
Optic Drives None
Computer Case: CaseLabs Magnum 8 double wide. air Filtration None
Fans x 10 Noctua intakes and 1 x exhaust all constant 1300 RPM
PSU currently Corsair 1200w order placed for Corsair AX1500i Air Filter Sylverstone 140mm Magnetic

Trying for a 24/7 4.6 clock not sure if possible? Or lower the below settings to lower the temps if cannot reach 4.6. Should try lowering one at a time or adjust all at the same time?

Is the formula for Off Set Mode BIOS V Core Volts minus VID volts or is it the other way around?

Prime 95 stable for 2 hours with these settings on auto not stable. Trying to lower the VTT CPU voltage below 1.10v, VCCSA below 1.15v, CPU PLL below 1.80v are these voltages ok on air looking at the temps? Want to adjust prior to a 24 hour P95 stability test. Then Off Set Mode and another 24 hour stability test.

Load Line Calibration & V-Droop. V Core in BIOS 1.27v at 4.5 Ghz. BCLK 100 multiplier 45 By All Cores.
CPU-z is reading the following. LLC Auto 1.23v, LLC Medium 1.26v, LLC High 1.29v When you start windows shouldn't CPU-Z read 1.27v?

Goggle eye : I think you're having the same problem I am : that these SandyBridge-e cpus don't play nice with higher RAM frequencies. try 1600 Mhz. See if that fixes it.

On my end I'd like to have some assistance to manage to run my RAM at stock 2400 speed and not 1600 like I've been doing with my 3930K.

I started a thread here, perhaps you can have a read-up : http://www.overclockers.com/forums/showthread.php/761539-Searching-for-a-motherboard-that-would-be-compatible-with-my-Ripjaw-Z-F3-19200CL

I've had no problems using 2400, but note that Google Eye is using an IB-E, not a SB-E.

However, it does also depend on capacity; it's easier to run 64GB at 2133, for example, and I always use 2T.

One thing though, most apps don't benefit that much from faster RAM. I do video stuff though, so it was useful
(AE gains about 10% from 1600 vs. 2133).

8 Gbs of memory compared to 16 Gbs memory. 16 Gbs will put a heavier load on the IMC may or may not effect the O.C. ability of your chip. It also depends on the quality of the chip you have installed. My I7 4930K LGA 2011has a weak IMC causing issues and makes it difficult to O.C. above 4.4 Ghz with 2133MHz memory.


SAMPLES OF MEMORY SPEED/TIMING

Memory is specified in speed and timing. The first number, in example is DDR3 the values that follow are the timing values listed as:

DDR3 CAS Latency - RAS to CAS DELAY - RAS Precharge - Cycle Time

Example: DDR3 2133 C9 -11-10-28

The first value, CAS Latency, has the highest influence on performance. The lower, the faster.

The 2nd and 3rd numbers also influence the speed of the memory and this is where a lot of people get snookered by a memory company into thinking the memory they are purchasing is faster than a lower speed.

In example: DDR2 1600 6-7-6-18 is FAR FASTER than DDR3 1866 9-9-9-24

DDR3 2133 9-11-10-28 is FASTER than DDR3 2133 9-12-12-28

Even though both are the same DDR speed and both are CAS9 rated, the two numbers - RAS to CAS DELAY and RAS Precharge are higher in the 2nd sample and therefore that memory is slower.


Cycle Time (the last number) does have an influence on the overall memory speed and it is always best to go for a lower value, however Cycle Time is not as critical to memory performance as are the other values.

This is good timing.

DDR3 SPEED -
DDR3 1333 - 5-5-5 - (6-6-6)
DDR3 1600 - 6-6-6 - (6-8-6 best or 7-8-7)
DDR3 1800/1866 - 6-8-6 - (7-8-7)
DDR3 2000 - 7-7-7 - (8-8-8) Intel 900/970/980 series 'stable' limit
DDR3 2133 - 8-8-8 - (9-10-11) Sandy Bridge 'stable' limit, can go slightly higher
DDR3 2400 - 9-9-9 (9-11-11) Ivy Bridge and Haswell 'stable' limit, SB-E 'may' run this too but not very easy.
DDR3 2800 - 10-10-10 (11-14-14) Haswell can run this, can go higher but you are now into 'tech experience' level speeds and not suggested
DDR3 3000 - 11-11-11 (12-14-14)

well judging by my hardware I SHOULD be able to run my ripjaw ram with my 3930k at it's stock 9-11-11-31 2400Mhz but tiral and error proved not frown.gif
post #366 of 407
Hmm, I don't know, CL9 at 2400 for an oc'd 3930K might be pushing it a bit, but it very much depends on the CPU sample, mbd, RAM choice, etc.

However, for all the talk & arguments about RAM speeds & timings, the reality is it's one of the worst parts of a PC to invest in beyond a sensible level. I originally bought a 64GB/2400 kit for my system because it was cheaper than a 2133 kit, but testing showed it didn't really make much difference to real application performance once one reaches about 1866MHz. Some benchmarks can be affected by RAM settings, like SuperPI, but real apps, not so much. After Effects can be an exception because of the high bandwidth it uses when exploiting GPUs for accelerated ray tracing (my system has four 3GB GTX 580s), but most apps don't behave this way.

So, don't worry if you can't reach 2400. You'd have a faster system overall by running the CPU at a higher clock. Indeed, in some cases I've bought a 2400 kit purely to make it easier to reach the intended target of 2133.

Ian.

post #368 of 407
Has anyone successfully Oc'ed the i5 2500k to 4.5 GHz on a Gigabyte GA-Z68XP-UD3 ATX LGA1155 motherboard? I have been trying a lot and it keeps on BSODing or getting stuck on the boot. Please keep in mind that I am a complete novice at this and that it is my first time OC'ing. I do have proper cooling in the form of a 212 Evo but I have no idea what to put all the different voltages at and if there even other settings that I need to be aware of. Any help is sooo very much appreciated.
post #369 of 407
Not on a UD3, but I had one at 4.7GHz with a UD4. However, you're in the wrong forum, this one is for SB-E CPUs.

dont really know if this is the place for this, but i am a long time owner of a 3820K. about a year ago i lucked out and had to return my processor to intel cause of some issues it had and they replaced it for me for free and i got a way better Malaysia chip instead of my costa rica chip that i had....anyway i got it installed it and clocked it at 4.625 with minimal vcore (something like 1.32 i think) and never really had any issues with it, here lately i have been playing around trying to get 4.875Ghz stable, but even with 1.495 vcore i was still getting some random BSOD 101 errors, so i tried my old clock and tried to stress test it and was still failing...is my chip degraded already....btw i have h100 and never see temps over 66C even under full load. and now i am running all the setting in the bios on auto, meaning no OC and when i try to run prime 95 i am getting this error from it




does this mean that my chip is totally screwed...if anyone has any advice please help me
