3770K on custom Liquid, help appreciated [ Solved ]

post #1 of 13
Thread Starter 
I'm currently working on pushing the overclock on my 3770K. Any help would be appreciated. Here's my situation:


Goal:

5Ghz Stable


Problems:

5Ghz bootable but having trouble tuning. (Unfamiliar with ASUS motherboards)


System:

3770k (Delidded, Coolab and Shin-Etsu)

ASUS MAXIMUS V EXTREME

Mushkin 2x8gb 1866 9-9-9-27

2x128gb Plextor M5P RAID 0

3x150gb Raptors RAID 0

2x660ti's (I game but not professionally and am on a single monitor)

Custom Water ( 2x PMP-500's, Tygon Tubing, Koolance blocks, Alphacool NexXxoS XT45, Silverstone Air Penetrators )



Other notes:

This chip runs fine at 4.5ghz, 2.8v, hyperthreading etc.. with turbo disabled. at those settings max temps are 65c under load.

I am overclocking with turbo and C states disabled. What i'm going for is a stable overclock I can run at 100% until the CPU dies.

I'm able to stably boot and even run benchmarks at 5ghz when using ROG Connect which is pretty simple. Temps under full load are 73c, 36c idle ([95, 8 threads, small ffts)

However, when mirroring the ROG settings in the BIOS, I run in to some issues. The system is bootable, but starting P95 with 8 threads will bluescreen.

I'm suspecting it's the VCC PLL, and also Load-line calibration at work here. Anyone have any place I can start looking?


EDIT:

Current Settings:

multiplier: 50
VCC: 1.49
CPU PLL: 1.6125 (No noticeable difference between 1.6 and 1.7. Outside of that range instant death)
Load-Line Calibration: Medium (High, Ultra, and Extreme were causing temp spikes)

[ I am at work, but if you need any more info I can get it when I get home. ]

I'm not sure if this will help, but if anyone gets me on the right track with the load-line and phase settings I'm offering 25$ paypal, regardless of outcome. If I get this working stably I'll make it $50.

TLDR so what is the current clock and voltage?

Did you change RAM to lower speeds?

Phase Lock Loop 'can,' but should not have a large effect on your overclock, it really only helps in rare cases as I understand, so I would leave it on default. In my case (I run 5.0 stable daily on a 3570k) messing with it only caused issues, and in fact did not help me stabilize anything, but your mileage may vary. The largest factor in stabilizing 5.0 for me was the elephant in the room...voltage. Voltage becomes exponentially more necessary the higher you go. When I try to go from 4.5 to 4.6, I only need an extra +.020, but going from 4.9-5.0 i needed almost +.060. I also found that using a higher LLC allowed me to not require as much added voltage in BIOS, but still gave me the same load VCORE, it does spike upwards or +.010, but it doesn't stay there.

Just because you can boot 5.0 does not guarantee that you will be able to stabilize it. Sometimes it just needs more voltage than is safe to feed it. Much of what I said is probably unnecessary, and not very helpful, but I am rooting for you! Getting 5.0 feels good. thumb.gif

inedenimadam pretty much nailed it... "The largest factor in stabilizing 5.0 for me was the elephant in the room...voltage. Voltage becomes exponentially more necessary the higher you go.

Not only lots of Voltage for me I also had to lax my Memory speed and Timmings... my 1866 9cl I went to 1600 to 10cl and got closer to a stable envirnoment,...

Really?

Lets offer cash rewards for help of a free speaking forum....the root of all...each to there own, I have an unanswered question on the forum, bet you get a lot of help....if this holds water at all im out of this forum, I have been reading since 2007 and never seen the likes.

Not sure why you have such a problem with this. Does your board have PLL Overvoltage? I know that going from 4.8 to 4.9 or above that I NEED to have that enable to ensure stability, other than that just increase voltage till stable and hope you don't hit a voltage wall.

Did you change RAM to lower speeds?

multiplier 50, 1.49v, CPU PLL 1.6125, LLC Ultra High

The RAM will not run at lower speeds without intensive tuning, in my experience with this particular set of Mushkin sticks they will run at their XMP profile, or not at all.

I really am sorry if this offended you, but what i'm asking in this case is something I know draws on a decent amount of overclocking experience. I don't want to be that guy that comes in and says "overclock my computer for me", this has been a 3 month project starting with a cutting torch and stick welder for the case and ending with the finishing touches on the overclock.

While my explanation may or may not appease you, I don't have the experience with Intel overclocking (or ASUS boards) that I feel is necessary to finish this project. To those here that are trying to help, I really appreciate the time taken in your answers and I'm going for another round of testing in about two hours.

Mate, I don't blame you, your stuck, throw cash at it, way of the world, you being desperate for results does not anger me, I really get it.

what angers me is (and not a word of a lie) I have been reading this forum for years and years, I never thought I would see the day this happened, in days gone by you would have been ridiculed for offering cash.....but now....who knows, I don't blame anyone for wanting to make a quick buck, I really don't but there was a time someone would have laughed at your offering while giving you the answers you seek.

Ach who knows mate maybe Im just projecting my values on to others, nothing wrong, just caught me off guard. Sorry

That helped a ton. I did a lot of lowering the vcore and discovered that I could get 4.7Ghz to hold prime95 at only 1.28 volts, 59c. The jump from 4.7 to 4.8 was monumental, costing me 1.37 volts to get it to hold. It's priming right now at that speed, and i'm leveled at 67c. I still am unsure how much LLC affects the actual voltages, but i left it at Extreme and then proceeded to volt down as far as it could go with my base clock (4.5).

Thank you very much for the pointers, and the time you took to answer. I appreciate everyone elses input as well. Would you kindly PM me your email?
