Error in Prime95 after 50 minutes...lol. Will raise cpu vcore 2 more clicks and restart Prime95.

seems like the RAM maybe causing the error.
you should not need that much v core at all.
can you show a screen shot of E-leet on the voltage tab?
we need to change some stuff here.
also get mem test here if you don't have it.
and mem set

Oh...to have such nice cooling ! I am running V-core a full 0.1V less than you and have slightly higher temps during prime95 with clock speed of 183 vs your 199. Then again, I am having serious doubts that my Aestek stage 2 cooling is working properly.
Hopefully everything is sorted out here soon for you .. neilkaz ..

Tried running memtest with the 4.168 oc and got an immediate error. Had six instances open with the first five at 920 and the last one set to all unused ram. Wanted to make sure it wasn't the sticks so reloaded the 3.75 oc and ran memtest again the same way and all six instances ran 200% without error. Screenshot below of cpu tweak and e-leet.

use E-leet to adjust voltages, and post a screen shot using prime95 under load of CPUz

Actually had to drop vcore down from +0.13125 to +0.11250 in e-leet in order for Prime95 to run without an immediate error. Ran memtest at the +0.1125 without error. Screenshots of e-leet, cpuz and memtest.

this is a perfect reason that I hate doing this remotely.. in person, you would have a higher OC a long time ago, but this way it takes so long, and ha s alot of wild goose chases/
so have you tried CPU VTT at 1.35v?

lol...If it helps, I am having a blast!! I am learning a lot from you! I appreciate the time you have taken to help me out. Plus if you were here in person, I wouldn't be learning as much. So no worries.
If 1.35v = +250 in BIOS for CPU VTT, yes I did try that, but I don't remember if the memory timings were set manually or if they were set to auto when I ran CPU VTT at +250. Not sure how much of a difference that would make?

I seen your mem timings are not the same every time. lol
every chip is different, and going to 3.6-3.8Ghz you can treat nearly every chip the same, and get good results, but you are crossing into territory that requires specialization, so some chips love VTT others hate it, same with other voltages, so I would try it see what happens, we will get this figured out. lol

Will give the cpu vtt another go at +250, and see what happens.
Current memory timings in BIOS are set manually to 9-9-9-24, tRFC is set to auto and current value is 88.

the mem timings, is another thing that really starts to come into play once you start pushing the max factory rated stuff.. lol |

lol....Getting closer.
Prime95 error after 13 hours and 7 minutes. Settings in BIOS were vcore at 1.40625 and vtt was at +200.
Changed vtt to +225 and left vcore at 1.40625, ran Prime95 got an immediate error.
Changed vcore to 1.40 and left vtt at +225, started Prime95 and has been running for 90 minutes so far.

lol...have found several settings that don't work.
Vcore at 1.40V and VTT at +225 - Error in Prime95 in 4h 26m
Vcore at 1.3875 and VTT at +200 - Memtest passed 6 instances at over 200% each, Error in Prime95 in 2h and 11m
Vcore at 1.39375 and VTT at +200 - Error in Prime95 in 11h 58m
Vcore at 1.38750, VTT at +125 and DIMM Voltage at 1.650 - Pass 20 passes of Linx, Error in Prime95 in 1h 57m
Vcore at 1.38750, VTT at +125 and DIMM Voltage at 1.625 - Error in Prime95 in 11h 53m
Vcore at 1.3875, VTT at +125 and DIMM vVoltage at 1.625, changed timings from 9-9-9-28 to 9-9-9-24 - Passed 20 passes of Linx, currently running Prime95
Changed DIMM voltage because when I was monitoring voltages in e-leet, the DIMM voltage would get as high as 1.69.

don't drop the DIM voltage, when running the RAM at full rated specs, you will need full voltage, if not a tad more, Intel specs that you have to keep the RAM voltage within .5V of VTT voltage.
E-leet will not report accurate voltages, if you want accurate voltage readouts, you will need to buy a good digital multi meter, and do it manually.

lol...my success rate at the higher overclocks, meaning anything close to 4.0Ghz has not been good...
 . Even though the high overclocks would pass 20 passes of linx and memtest, it would not pass Primed 95. All the errors in Prime95 were all while testing at or above an fft length of 512, which if I read the info on Prime95 right, these are all considered large fft's and most of the time points to a problem with memory. So I lowered the overclock to the settings below and it passed 24 hours of Prime95.
CPU Clock Ratio ( 20X )
CPU Host Frequency (Mhz) ( 179 ) MCH Strap ( Auto ) CPU Uncore Frequency (Mhz) ( 16X) CPU Clock Skew ( 0 ps ) Spread Spectrum ( Disabled ) PCIE Frequency (Mhz) ( 105 ) Memory Feature Memory Speed (Standard) Memory Control Setting ( Enabled ) Memory Frequency ( 1067mhz / 2:8 ) Channel Interleave Setting ( 6 Way ) Rank Interleave Setting ( 4 Way ) Memory Low Gap ( Auto ) tCL Setting ( 9 ) tRCD Setting ( 9 )
tRP Setting ( 9 )
tRAS Setting ( 28 ) tRFC Setting ( 88 ) Command Rate ( 1T ) Memory timings set to super talent specs.
Voltage Control
EVGA VDroop Control ( Without VDroop ) CPU VCore ( 1.375V) CPU VTT Voltage ( +50 )
CPU PLL VCore ( 1.8 )
DIMM Voltage ( 1.575V )
DIMM DQ Vref ( +0mV ) QPI PLL VCore ( 1.250V) IOH VCore ( 1.250V )
IOH/ICH I/O Voltage ( 1.525V )
ICH VCore ( 1.100V ) PWM Frequency ( 800 Khz ) CPU Feature Intel SpeedStep ( Disabled ) Turbo Mode Function ( Enabled ) CxE Function ( Disabled ) Execute Disable Bit ( Disabled ) Virtualization Technology ( Disabled ) Intel HT Technology ( Enabled ) Active Processor Cores ( All ) QPI Control Settings ( Enabled ) QPI Link Fast Mode ( Enabled ) QPI Frequency Selection ( 4.8GT/s ) PnP/PCI PCI Express Maximum Payload Size ( 128 ) It appears from the testing that when the memory goes above 1500mhz, it does not pass Prime95 even though it will pass linx and memtest.
Justin in your experience, what are your thoughts? |

Yes, some RAM is very tough to get to run full speed with good timings, sometimes you have to tweak a lot of the sub-timings to get it to pass, that is why I hate AUTO setings. lol

lol...I fnally figured that out. I have the timings manually set. I upped the Bclock to 189 which put the RAM running at 1512Mhz, raised the DIMM to 1.65 and the VTT to +150 and Prim95 got an error in a hour. Dropped Bclock to 187, DIMM and VTT the same, RAM is running at 1496Mhz and Prime95 has been running for 13 hours...lol.

Yes it did pass. Thank you for asking.
Also it appears with the testing done with the super talent RAM that anything over 1500Mhz, the command rate needs to be set to 2T instead of 1T. All other timings are the same.
Right now Prime95 is at the 19.5 hour mark testing 4.0Ghz. Bclock is set at 191, Vcore at 1.375, VTT at +250 and RAM timings are 9-9-9-28-88-2T.
And Justin, thank you for all your help with the overclocking. I appreciate all your advice and time.
Maybe some help overclocking the 5870 next...lol?

This just started happening today on internet explorer with the mouse pointer. Every few seconds the mouse pointer toggles between the normal pointer and the busy pointer. Here is what the busy pointer looks like for reference.
 I experienced this before when the overclock was over 4.0Ghz and the Bclock was set at 189. When I lowered the Bclock to 187, it stopped doing it until today
It only does this when on internet explorer. It does not do this while on the desktop or with any other program.
Does anybody have any ideas why it's doing this?

@rholyrag I was re-reading your thread here and I noticed your memory speed. Do you have 1333 memory? are you still currently at 1067mhz?

AndydViking, no my memory is 1600mhz and if my math is correct...lol, it's currently running at 1524mhz. Which memory do you currently have in your rig?
My Bclock is at 191 with a ratio of 2:8, which puts it at 1528 and cpuz has the memory speed at 762.1 and when I double that it puts it at 1524. Does that help?

@rholyrag Yes thanks alot it does help. In your first post I thought it said you had mem running at 1067 mhz. I have 1333 and it's holding back my overclock but I need to hold off buying higher rated ram for a bit but eventually will. Just wondering if you had run your OC with similar ram.

Overclock Update.
lol..I was going to update this post with screenshots, but it will not let me upload any files or images. I am getting this error message. "Dear Valued Customer,
An error has occurred, the webmaster has been notified of this error. To continue placing your order, please contact us at, 1-866-81-STORM. If possible, please also email us how you got to this problem. Warm Regards, Digital Storm Support Team 1-866-81-STORM support@digitalstormonline.com" 203 Bclock x 21, 3Dmark score of 19815. Will post screenshots once the site allows it.
