Brutality Posted October 14, 2011 Posted October 14, 2011 (edited) The following setup is 20-pass LinX stable and I even did a dual-pass memtest86+... BCLK: 100.0 Turbo Ratio: By Per Core Ratio Limits: 46 Internal PLL Overvoltage: Disabled Memory Frequency: DDR3-2133MHz EPU Power Saving Mode: Disabled DRAM Timing Control: According to X.M.P. Profile Load-line Calibration: Ultra High VRM Frequency: Manual VRM Fixed Frequency Mode: 350 Phase Control: Extreme Duty Control: Extreme CPU Current Capability: 100% CPU Voltage: Manual CPU Manual Voltage: 1.310 DRAM Voltage: 1.65000 VCCSA Voltage: 0.93750 VCCIO Voltage: 1.1375 CPU PLL Voltage: 1.55 PCH Voltage: 1.05000 CPU Spread Spectrum: Disabled Now, If I bump the frequency to 4.7GHz, the system won't let me get into Windows, it just hangs after a while at the logo (loading Windows)... I even tried putting the vCore up to 1.35 (not going any higher, cuz I want to follow Intel's specifications) This just puzzles me... How I ended on the bios settings: http://forums.overclockersclub.com/index.php?showtopic=185512&st=0 As u can see from the topic above, Nuclear was my mentor in overclocking my 2500k, but he's been gone for months and are not replying to my PMs, so I don't know if what I did after his last reply is right... Bonus question: Before LinX I did a 12h p95 blend test followed by a 3h Large FFT test (p95) (according to http://www.clunk.org...-beginners.html) finalized by a 2-pass memtest86+. Now I know that the 12h 95 blend test is substituted by LinX, but will it also substitute the 3h Large FFT test? (I think it's meant for testing memory), so that I only need to do LinX and memtest 86+? PS. It's cold now, so that's why I'm trying to OC my 2500k again (in the summer I had high ambient temps which stopped me from further overclocking) Edited October 16, 2011 by Brutality Quote Share this post Link to post Share on other sites More sharing options...
wevsspot Posted October 14, 2011 Posted October 14, 2011 Hey Brut - Memtest 86+ doesn't really stress the memory subsystem. It's great for detecting errors under nominal operating conditions though. Using large FFTs in OCCT, LinX, Prime95 etc. will stress the memory, nb and imc - so I think that's a better stability/stress test.

EDIT: I figured out the boot problem... I reread the topic I was referring to and found out I needed Internal PLL Overvoltage to be enabled lol But I still want an answer to the question above Edited October 16, 2011 by Brutality Quote Share this post Link to post Share on other sites More sharing options...

You cannot "set" large FFTs in LinX. That is a miss-quote on my part. And since I'm clarifying - when I refer to LinX - I'm actually talking about the simplified use version (aka IntelBurn Test). IBT has a simplified easy to use GUI. From there you can set the memory usage anywhere from standard to maximum. The more memory used, the harder it stresses your system.

Oh! lol So when I use LinX (with minimum 2800MB ram used for 4GB - I usually select the 3072MB one), I am doing the "large FTT" thing? So that means I only need to spend 15-20 mins (LinX 20-pass test) to see if my system is super stable? EDIT: When is Memtest used then? (if it isn't used for stresstesting, when do I use that?)

wevsspot Posted October 18, 2011 Posted October 18, 2011 Hey Brute. For simplicity sake let's say that selecting the largest amount of available memory to test when using IBT closely approximates choosing the large FFT setting in other stress testing tools. Essentially, when choosing large FFTs you are maximizing the memory usage while minimizing the stress on the cpu. You get a similar result when selecting the largest amount of available memory when using IBT. However, I don't know how well IBT minimizes/isolates the cpu stress when testing large amounts of memory. Either way, IBT using the largest amount of available memory is a brow beater and should quickly show any system instability. For my stress testing purposes (and even initial setups at stock settings) I use Memtest to confirm that I'm ready to move onto the next step. I do this before I even install the OS. I want to make sure that the memory and memory subsystem is stable before I put time into installing the OS, updates and applications. If the build passes Memtest at stock settings then I proceed with the OS installation. In the simplest of terms I use Memtest as the initial indicator of memory and memory subsystem stability. Memtest is also helpful in identifying memory or memory subsystem issues that might be causing failures when running other stress testing applications, or even during regular use of the PC. Of any memory testing you can do, I believe that Memtest is the best at isolating the memory and memory subsystem from other influencing stability factors. My normal stability testing regimen usually goes like this; Memtest 86+ ran from USB on completed build but before OS install Pass = proceed Fail = identify failure mode > correct > retest IBT recommended memory size 1 hour IBT maximum memory size 1 hour OCCT Medium Data Set 4 hours OCCT Large Data Set 4 hours Prime95 Blend 8 hours Prime95 Large FFT 8 hours Video System Stress Test - use anything you like; 3DMark, Vantage etc. Then off for some intense gaming Note: I do not perform this entire testing regimen on regular every day builds and no intention of overclocking or other battering of the hardware. This is my testing regimen for new hardware, overclocking and personal builds. If I'm building for a regular joe customer they get Memtest and a 1 hour run of IBT.
