Overclocking Question

[Huberto]

I am a newb to overclocking but I've taken first steps and would to get suggestions about where to take it from here.

My rig is:
CPU --Core i7 920 w/ Xigmatek Dark Knight cooler
Corsair XMS3 6 GB 240 Pin DDR3 1333 Mhz
EVGA x-58 SLI mobo
2 x Gigabyte GTX 460 1 GB overclocked to 714 Mhz
Corsair HX 1000
Windows 7 Home Premium

So based on my hardware I should be able to get a decent overclock, right? However, am wondering is it advisable to purchase 1600 Mhz RAM to overclock beyond where I am now which is ~3.3 Ghz?

All I've done so far is increase the CPU Host Frequency to 165 (165 x20 = 3300) and set my memory frequency to 2:8 = (8 x 165= 1320)
I also increased my memory latencies to their tested numbers 9-9-9-24.

The resulting overclock is stable (no more than ~65 degrees C at full load) and I didn't have to increase the voltages at all.

What should I do next?

Word to the wise, don't go for 4 Ghz with a Xiggy S1283. It's just a guideline since you already know the basics in overclocking. Aim for around 3.6-3.8 Ghz.

That's my tip to - and I do a lot of OC since years - but between 3.6 and 3.8 is just still on the safe side - and if you go above these few more frames are really not worth the danger of burning the CPU.

It's just a minimal difference from 3.8 up to 4 GHz!!!! - but I would also do a 24 hour stress test - and check the min max temperature during this test there are a few tools out -

Download an easy one for temp check RealTemp: link: http://www.softpedia.com/get/System/...eal-Temp.shtml as just a temporary sporadic temp check may give you a wrong impression of the peaks!!!! And important are the CPU core temp. not the CPU itself....so this tool is made to give you these information's....

And look of course that you have a sufficient cooler - but I see you have - it should do the job for this OC!!!!
Another tip for safety - not touch the voltage - just go as high as the standard voltage allows stable - all other is a fine tuning on the knifes edge...

There is really no chance of burning the CPU if you know what you're doing, and not racking up insane voltages wich wont be necessary for 4ghz. And even with high voltage, your chip wont just suddenly burn, it's going to slowly degrade over the years.

The only dangers of overclocking that I can think of, is that you have an uber cheap PSU or a board with not enough mosfets.

I burned two!!! CPU's but that was about 3 years ago!!!
Now it is like Crazyeyesreaper stated there is a throttle and the CPU back!!! But this safety hasn't exist 3 years ago!!!
Still my rule is I oc only as high as the standard voltage allows - to a stable oc!
Of course some may increase the voltage - if some have a very good cooler no problem....but I not do it....(as I'm a burnt child...my previous burnt CPU was 700USD CPU - and that money throwing out of the window - hurts a bit))

voltages dont matter much look at the CPU manufacturers info

example Phenom II line of cpus can handle 1.5v safely a 965BE comes with 1.4v default, upping volts from the default to 1.5 allows most users to hit 3800-4100mhz on the cpu, Intel has the same thing they give voltage ranges that are safe to use. its not as cut and dry as it use to be.

rule of thumb

on AMD cpus of the Athlon II and Phenom II lines stay UNDER 60'c at all times
for Intel cpus of the Core i3 i5 i7 variety stay under 80c at all times for best results / longevity,

the above rules of course are when running PRIME 95, Intel Burn Test, LinX, OCCT, etc etc those tools put more load on a cpu then any actual cpu task thus if you stay under the above temps with those stability testing apps your perfectly fine in terms of a desktop / gaming enviroment.

I agree with Devil modern day MOBOs are pretty advanced they don't even boot if some value is fed incorrect or insane, moreover it displays the the actual no. of voltages that a CPU can handle.

Aye the gpu still does it job, managed to oc her to the Amp version (zotac) for some games.
(games played in hi def, that require a bit more bandwidth. hate micro stutters)

Ive been putting some money each month, towards "help the old blind man`s GPU fund."

When DX11 becomes the norm. then the gf580 seems a nice buy for the system.

The hopefully DX11 will allows the 860 to do some of the MLAA, as you say the cpu is hardly breaking out into a sweat.(system tweaks)

[♔KillZoneGB♔]

I think you have done a good job so far with 1333 @165.

Spoiler Alert, click show to read: 

Best thing would be to find out, what`s the max memory Freq`s are for that type of MB.
(might need a bios update)

if your going to replace the memory with some Higher spec, IE 2500mhz
you might need to lower the cpu multiplier, to stop it from burning out (stock fan)

Corsair ram fans might come in handy as well(£19)

Remember Heat kill`s the performance and could null void your OC

4ghz + is safe on a better cooler but with a Xigmatek as previously mentioned 3.6 is easily doable 3.8 should be the upper limit of what you would try reaching.

4ghz + requires larger air coolers, examples

Noctua D14, Thermalright TRUE, Venomous X, Cogage Arrow, ThermalTake FRIO, Prolimatech Megahalems etc,Corsair H70, all of which are expensive compared to the performance gain of 200mhz, that said there is still performance to gain after 4ghz, but its hard to get there with 24/7 reliability.

yea i gotta agree with Devil only cheapo mobos + cheap psu will cause something to fry

hell ive caught old nforce 570 boards on FIRE with extreme volts and they continued to work, just had to downclock the cpu after that.. anyway, it took 1.9 volts on an Athlon X2 to cause that to happen and it was because I started popping capacitors on the board. overall its nearly impossible to fry a cpu,

theres built in limits where cpus will throttle back if there to hot, high voltage will just degrade a chip over time. etc
