3770k Installed. Want to check everything looks ok + overclocking tips!

yeah if they are mismatched sets of ram (timings ect)

best to test with just one kit ?

for a quicker stability test why not do 5 runs intel burn test on high stress and then 10-15 minutes of gaming,look in event viewer for any cpu/memory related parity warnings/errors and up the cpu v to suit till there's 0 errors/warning

that's what I do,much quicker
 
in event viewer I just concentrate on cpu parity 19 errors/warnings and memory related ones though ive never had those

it will say cpu or memory for each warning/error

and the bsod codes are 124 not enough cpu v or secondly cpu/vtt
101 bsod means not enough cpu voltage

games tend to crash to desktop if cpu v is too low on ivybridge,sandybridge that doesn't happen
 
OK, well I think I bodged my first overclocking session up earlier today by setting my ram timings too tight! I just got home, loaded optimized defaults, set ram timings to 8,8,8,24 at 1600mhz....was dodgy starting up, got into windows, Prime failed in seconds, internet explorer crashed, then I got a BSOD (0x00000003b fault code).

This was with CPU at stock so the ram timings I set were probably causing the instability and severly handicapping my overclock ( or at least that's what it looks like anyway).

I will start from scratch and leave ram timings on auto and just see what my cpu can do.

However, with the cpu overclocking as well as those tight ram timings, it did seem even more unstable (not loading windows, BSOD sooner) although it did all seem very random.

Ok this is a LOT more promising. Just booted into windows no problems at 4.4ghz and 1.2v :D. With the ram timings set too low I couldn't get into windows even at 1.3v!

Think I have something to work with here. Will try some stress testing.

(such a noob mistake I made with ram timings :( )
 
Ok, one hour prime stable with 1.2v set in the bios and 4.4ghz speed. No Whea errors. Seems pretty stable.

Not sure where to go from here. Temps are under control (keeping under 80 degrees), not sure whether to be happy with 4.4ghz and see the minimum volts it can do 4.4 on for better temps or push it to 4.5/4.6 and see if it holds out at 1.2v.

It is clear from yesterday that 1.3v and over is just too hot on air. I think I would need water cooling or at least something like a corsair h100 to use that amount of volts. 1.2v seems to keep temps around 70-75 with the odd spike to 80 which is ok right? I would imagine for normal use, even under load it wouldn't go above 70.

I would try 4.5ghz,if your stable at 1.2v for 4.4ghz then you have a decent chip

I can do 4.5ghz @ 1.212v temps are around 76-79c

for a higher oc you would need to delid it which is risky tbh

Thank god for that. I really thought I had a stinker that wouldn't even load into windows at 4.4ghz and 1.3v!

Yeh, I think I will keep Prime running for a bit longer ( 2 hours in total) to make sure 4.4 at 1.2v is at least pretty stable. Then I might just try 4.5 then 4.6 at the same volts and see what happens

One thing I am concerned with though is that although I have my ram running at the correct frequency ( 1600mhz) the timings when left at auto are 11,11,11,29 which is obviously pretty slow. I am worried that when I tighten these up to their rated timings 9,9,9,24 it might cause instability. Does it work like this or is the ram separate to the overclock on the CPU? I mean before the problems were caused by me setting the timings at 8,8,8,24 which is tighter than what two of my sticks are rated for. Setting them at their rated values shouldn't affect the cpu overclock should it?
 
I doubt you'd manage 8-8-8-24

but 9-9-9-24-1t or 2t shouldn't be a problem

if too tight it simply won't boot or will crash ect
 
Glad to see your CPU is doing better now, thats next on my list - To see how low I can get the voltage but still be stable at 4.5.

With my Chip at 4.8 using 1.35 volts my temps peak at 85 under P95, but i've got a load of new fans to put in my case and a fan controller so whould be able to know a few degrees off that temp.
 
A better cooler and using liquid ultra might give you a bit more oc headroom, but looks like you have a pretty ok chip.
 
Ok 2 and half hours prime stable and max temps of 78/79, normally sitting between 70-75.

Pretty pleased with that. Time to try 4.6 at he same volts :)
 
you need to play some games aswell,you'll find it will probably crash to desktop

I can pass ibt/prime with 1.88v @ 4.5ghz,play a game and it crashes within seconds and requires more cpu v
 
Well, nearly an hour running prime95 with 4.5ghz and 1.2v set in bios (though cpuz shows vcore goes up to 1.23-1.24 under prime load) and all seems ok.

I think I will just stick with 4.5ghz and work voltages around that multi to get 100% stable with minimum of heat. I think it will just be difficult to get much above 4.5ghz with my air cooling.

Not too bad a chip after all thankfully.



All look ok?

Good.

Prime still going, all seems fine, though I have to go to work in a bit.

I am worried that setting my ram timings to their proper rated values is going to upset the overclock though : / . Is ram timing linked to the CPu overclock or will it just be based on the ram itself ( which should be fine as they are rated for 9,9,9,24)?
