what is holding my OC back? X58 Sabertooth + E5640 (followed miahallens tut)

post #1 of 5
Thread Starter 
specs:

Asus Sabertooth X58
3x2GB GEIL 1600
Intel Xeon E5640 ES
SilverStone 850W
( I doubt GPUs & SSD/HDDs are relevant, if not let me know)

couple months ago I decided to OC my rig - I followed miahallens tut.. I got to 4Ghz, did about 20 loops IBT, passed no probs.. then few days later BSOD.. ever since then I have been having BSODs every ~3 days
last weekend I dropped back to 3.8.. no BSOD all week (so I presume 'stable')

following miahallens guide, I found my mobo can do 210bclk
previous owner to the CPU had it @ 4.2 stock V on a GB UD5/7

either the owner is lying.. or .. is my mobo that crap??
the RAM is running *under* its rated max (running @ 1531 iirc, when CPU is @ 4ghz / 191bclk)

what I be doing wrong?
or should I change my mobo?

keep in mind the CPU is a 32nm quad

dont know what graphics card you are using or how many of them but it could be a power issue. your power supply is only good for 720watt peak (its claimed at 750watt but if you do the maths 12v x 60A = 720 watt). while that should be enough for a high end graphics card and an overclocked cpu it might be the previous owner had a better power supply that provided a higher, cleaner output.

secondly he may have more experience and been able to push it higher. there are some key voltages needed when overclocking 1366 chips. you need to use all of these to achieve higher overclocks, just using the Vcore isnt going to give you the best result.
the voltages used mainly are the Vcore, CPU VTT, ICH Vcore and IOH Vcore. the CPU VTT is just as important as the CPU Vcore because as the cpu speed and memory speed go up (and you need to increase memory and cpu voltage) the Internal Memory Controller (IMC) has to work faster as well and needs more voltage, this is were the CPU VTT comes in.

You might want to try higher multi with lower bclk. Some times a chip might to better on odd or even muiti. My chip here can x21 or x23 I can't use a x22 at all for anything above 4ghz. But others report good results with x20 and x22. Not me though.

umm.. my PSU is 850W where are you getting the 720W figure from?
edit: sorry, I see where you are looking now: my sig.. sorry it's incorrect - the PSU is listed in OP
I'll remedy that now

it isn't a PSU issue as I have tested with two different combinations:

combo1: X1900XT + X850XT
combo2: 4350 + 5450

I get the same result
as I mentioned, I followed miahallens OC guide so I'm a *little familiar with the other voltages I've messed around with pretty much all of them to no avail - the only thing that has helped so far is going down to 3.8

I will add tho, that I came across the s1366 OC guide here on OCN.. it mentioned PLL voltage - something miahallens guide never touched on (rather strange imo) - I have set the PLLv to what is recommended by OCN guide.. am sitting @ 4ghz & will see if I get a BSOD

I like your case btw - not many around, but a nice one

well I cannot go a higher multi - I'm sitting on 191x21 - thats as high a multi I can go.. in my testing, the mobo seems to max out @ 210bclk.. so I *could increase blck to 200 & *drop a multi *shrug
