i7 930 OC help, BSOD 124 and 101

[jmgdotcom]

Hey, new to this forum, but been watching TTLs channel for a while now, i hope im posting in the correct place i did a quick search before i posted

im having a few issues with my i7 930 overclocked to 4GHZ (200x20) its been running perfect for months but in the last 3 weeks i started getting 101 and 124 BSOD's (amongst others), i first thought it was a windows issue so i did a clean install but made no difference.

i then went to my overclock thinking it wasn't as stable as i thought, so i increased my vcore slightly but again it still persisted, any one any suggestions?? below is my overclock settings and rig setup, i have a fear that this may be caused by the silicone deteriorating, its happened to me before with similar symptoms

I7 930 D0

Gigabyte GA-X58A-UD3R

ASUS GTX580 (stock speed until i get this sorted out)

Corsair XMS3 6GB 1600mhz

880watt Hyper 85% PSU

H100 (with OC temps around 66deg for 12 hours folding when i did it months/years ago)

Overclock

Load line calibration - AUTO (wouldnt work on any other setting and i have no idea what auto has set it to)

CPU vcore - 1.356 (iv tried higher but issue persists, will boot at 1.35 but bumped it up one for stability, cpuz shows it as 1.328)

QPI/VVT Voltage - (Auto (wont post on anything less than 1.295, iv tried going up as far as 1.375 but issue still occuring, i was to scared to go higher)

CPU PLL - AUTO (currently running prime 95 on 1.84 to see it it helps)

DRAM voltage - AUTO (actually 1.65 which is correct for the ram)

evertyhing else is AUTO i never needed to manually set them so i didnt

Clock Ratio - 20

BCLK - 200

Memory Multiplier - 8

QPI CLK - AUTO

XMP - Disables

Performance Enhance - Standard

All timing setings are auto

If anyone has any ideas as to what is causing this i would appreciate the advise as im not an expert in overclocking and am beginning to get to the stage where im not sure what else to try, i would like to keep my overclock at 4GHZ so i would like to sort this out without dropping the frequency, again its been running for maybe years at these settings

cheers

Set LLC at level2.

Qpi/vtt start with 1.38v and try lower volts when stable.

Cpu PLL 1.84-1.88v

Dram voltage 1.64v and set rated timings manually at 1600mhz.

Uncore at 3200 (2x ram)

1.356v vcore should be enough.

You could update bios,should improve stability if you still have old FB bios version.

100% stable under what load? If it's just games then that's not a reliable stress test.

Thanks for your reply

I have all those settings in, posted and loaded windows no problem, changing LLC to level to put my vcore up to 1.344 (in cpuz) temps are the same so im not worried about it, the memory timings were incorrect for my ram they read 8.8.8.20 when its actually 9.9.9.24

i will let it fold tonight and see how it goes

can i ask, why would it not boot when i set the QPI/VVT to 1.38 and everything was at auto but when i used your settings it did?

aso what affect did it make manually puting in 1.64 into DRAM and reducing the uncore to 3200?

I would like to learn more about overclocking this is why i ask

***The_protocol

it was BSOD at any time whether it was under load or not, even idling. Sometimes it would go a whole day with no issues and the next it world blue screen 5 times, when i set it to stock left it 3 days and 2 nights folding and it was fine thats what led me to believe it was my overclock

 

[kilobravo]

It will improve stability,when these voltage is set manually.Higher uncore need more qpi/vtt voltage,and is only good if you have 2000mhz ram(4000 uncore(2x ram).

Then your clock simply isn't stable and you should run a stress test for at least 6 hours that fully maxes out your CPU, start overclocking again, starting at about 3.6Ghz and keep going till you don't get any BSODs under load. If you don't get any under load yet at the same clock get them at idle then it might be something else like your board that is not up to overclocking or just a dud unit.

Thats what i initally done when i first overclocked it, started at 3.5Ghz and worked up, it folded pretty much 24/7 for 2 months and no BSOD this issue has only started in the last 3 weeks

With these settings in it run for 5 hours folding and then got a 1a BSOD, i then lowered the frequency to 3.8 (181x21) to see if a lower BLCK would help and lowered the uncore to suit (2x ram) it folded for 14 hours with no issues, would it be worth trying increasing the multiplier and lowering the BLCK maybe 182x22? and letting the ram run slower

If you could make a screenshot like this with linx or foldingclient running it would help a lot.

200x19 is better settings at folding.

Go back to your old clock but keep increasing your memory timings, might stabilise it.

Here is your screenshot

I think its the ram at 1T.At rated 2T it should be stable.Maybe the xms ram isnt that good when tightened a little.You could try with 1.66v in bios.

 

[jmgdotcom]

Just thought id give you an update, I changed it to 2T, run prime for 12 hours with no issues, then started to lower my Qpi/vtt until it was at its lowest stable voltage, was also able to lower the vcore slightly to 1.344 and its been folding with no issues for 48 hours

Thanks for your help and advice guys, it was much appreciated.
