New to overclocking (i7 950 lga 1366 x58)

post #1 of 4
Thread Starter 
Hello all I am new to overclocking and so I decided to join the forums after some time of reading and being a ghost.

So far i have successfully hit 4.0 ghz with ram at 1531 mhz wit these settings

c1e + eist(speedstep)- off
all spread spectrums- off
Turbo- off
HT- on
load line calibration- on
Multi- 21x
blck- 191
uncore- 3063
vcore- 1.3
qpi/uncore- 1.35
ioh- 1.2
ich- 1.2
cpu pll- 1.88
dram bus- 1.65

my system specs are all listed in my profile.

So the thing is when i run small fft's on prime 95 there is absolutely no problem but when i run large fft's it will blue screen or a worker will fail
i just want to hear other experienced opinions on my novice OC for any first hand tips/guides at what i should do. I will post bios pics or pics of anything needed just ask! I THANK YOU ALL IN ADVANCE FOR YOUR HELP IT IS VERY MUCH APPRECIATED THANK YOU THANK YOU THANK YOU!

on a side note my pc is running 100% stable at stock 3.2 ghz with only vcore set to 1.0625 and ALL OTHER BIOS SETTINGS AUTO aside from things like boot priority, q fan control, and ahci mode

scroll down and you can see all the Links i used to help me. I had the Sabertooth board before I moved to the one I have now bc the Sabertooth was RMA and also had a issue where it would only read 4gb and not 6gb of my ram. What i am getting is the Sabertooth MB may hold back your OC a lot. Look throw the post I posted and you will find ALL the information you need pulse more.

You might want to try out a higher multiplier. Try out these settings and see how they work for you. Note that your RAM will be running at 1670MHz and may need its timings loosened.
