Oc'ing on new rig

[craven]

This is my first post so i'll start by introducing my rig.

I'm probably not that experienced in oc'ing as some of you guys but i came quite far on my last board until i ripped my northbridge in half... :P. I got my E6420 at 3.5ghz (1.375v) on my Asus P5n-e sli. Never touched my ram and vid card. Anyways after i upgraded my mobo and was able to get me a q6700 cheap i decided i wanted a new vid card to. And this is the result:

Antec P182 - 6 Nexus Real Silent 120mm Fans
DFI LanParty LT X48-T2R + Silenx 60mm fan @ Northbridge
Intel Q6700 + Scythe Mugen @ Stock
Kingston 4x1 GB DDR2 HyperX @ 800mhz 4-4-4-12
Sapphire HD4870 + Thermalright HR-03GT/HR-11/HR-09S + Scythe Kaze 100mm fan
Ichbinleise (pc power & cooling mod) 700 watt
1.5TB Storage



Now i'm busy oc'ing my q6700 but i can't seem to get any success. Every oc i try fails these were the last settings i tried (i used clunks oc'ing dfi addon and changed some things):

I'm a complete noob when it comes to memory oc'ing and this is the first ever dfi board i've used so correct my if i'm doing something completely wrong. The lines i made bold are the ones i'm pretty unsure about.

Using these settings my rig won't even boot. Have to crawl inside my pc and use the jumper to reset. Holding the power and reset buttons won't even work. Does anyone have any idea as to what i'm doing wrong?

Hello Craven,
Welcome to the forums.

I would change the memory divider/strap to 333/667 and leave overclocking the memory until after you are done with the Q6700. 3.6Ghz at 360FSB with a good slug of vcore maybe 1.45v should do it.

The LTs are a good board, but some including Kelainefes have reported problems with the 400 straps.
333/667 is a better place to start.

Also what is the rated vdimm for your RAM? it looks like you are aiming for 800mhz with 2v at 4/4/4/12
Most RAM needs a little more like 2.1v to manage that with stability.

Also you have all 4 DIMM slots filled so i would think you might need more voltage on the north bridge.

Finally which BIOS are you using?

[craven]

thanks for the help

i've set everything to what you said. And yes i was aiming at 800mhz 4-4-4-12 @ 2v it was always stable at that setting. But i've raised the voltage to 2.1 now. nb voltage is set to 1.504v now.
cpu clock at 3ghz and dram speed to 333/667.

i can't seem to find anywhere which bios i'm using. I did update it about 2 months ago because my memory didn't work. This was thanks to this forum btw, the only place where i could find what my post codes ment :P.

Also could someone explain the CLOCK VCO divider to me and explain how the dram speeds work?

edit: wooohhoooo at least it's booting now at 3ghz

Overclocking Basics; HTT, CPU Multiplier, Memory Divider - Tom's Hardware : Tight Timings vs High Clock Frequencies
This explains alot about timings and frequencies, it covers the straps quite simply too.

Your CPU will prolly go a good bit higher, i would aim for 3.6.

Leave the multi at x10 and the strap at 333/667. The loosen the RAM timings to 5/5/5/15 for now and change the fsb to to 360.

You may need a healthy dose of vcore, around 1.45/1.5v (to be safe) with your cooling is acceptable with 65nm chips.

If this works out stable you can go for a higher clock like 3.8Ghz or if you get to 3.6Ghz and are happy then you can go back to finding out what strap will give you the highest stable frequency.

Finally if you like then try playing with the RAM timings, but you will see little if any performance increases.

i was aiming for that to. I'll try that later on i don't have to much time left right now.
thanks for the help for now.

Welcome aboard, craven. nice tidy job on the build.

[craven]

thanks you don't want to see the back of my case though :P

[Clunk]

Welcome to the forums

For 3.6GHz, it shouldn't need that much vcore, usually about 1.36-1.43v depending on the CPU, and as he has a high multi CPU, it should hopefully be at the lower end

[craven]

one more question though. about my temps.
What should i consider my max. I always kept 60c for the cpu and never really watched the separate cores.
But they usually are 10c higher. What temps should i consider for max?

[Clunk]

Don't worry too much about the temps, 65-70c depending on the voltage and cooling is ok really.
