I have i7-2600k with asus maximus extreme-z and it has an e-z oc to 4.6ghz, (1866mhz g-skill ram,) I cant seem to get much past that yet im watercooled and at 30c, how do I max it out and get 5.9ghz like my multi lets me go up to, or even those people that get like 8ghz, cuz i have it cool enough to pass 6, how would I go about doing that? I have read many guides, and leave my ram at 1600mhz instead of 1866 (default) and then try to increase voltage and the fastest I can get is 4.9 before it crashes (I do it in the OS or using ROG CONNECT) , does anyone know what I would have to do since I can't touch the fsb (must leave at 100) and upping just voltage and multi only gets me so far, I like that the board has it set to 4.6, and at idle its chilling at 1.6 then turbos up to 4.6 under load, but It is so cool, i could easily push it past 6 and keep it under 70c.... massive cool. So how would I go about doing that, like you see people with those extreme OC's 6.5 etc, I could reach that with my custom setup, or would I need like 2133 mhz rated ram, or what. In most guides they say "ive seen 5.X or 6ghz w/o touching the ram etc... but yea I let the mobo take me to 4.6, sets my 1.5V 9-9-9 28 2T ram to 1.65, and then idk what to do from that, should I set the ram Mhz lower and use memtweak to raise the 9-9-9 ? and how much etc, or do i not have to bother with that to get past the 5.0 mark.

Here is another question I had (long read, if you just want to answer above that ismost important).

///////////////////////////question 2

Hey guys, I recently built an amazing computer with the i7-2600k processor, and used as ASUS Maximus extreme-z motherboard (basically the most beautiful mobo on earth, they even have one for servers that is so redic. link for server version here anyways, I have the extreme-z version of that and in the new gui bios I just set the ez-overclock to 4.6 and it is completely stable And CPU-Z backs that up, core temps are 35-45c with corsair H100 water cooling, the processor came with an even smaller heatsync then the i7950 (and the 950 was running wayy hot when I got that) but i tried it and at stock voltage and stock heatsync it was only 35~ c, so the new 35nm i7-2600k is sick as hell.

ANYWAYS, I have a mid tower case (cooler master HAF 912) and want to build a server, and im thinking about going AMD because I want it to be cheap but as powerful as possible for the $$$, I have about 700 to spend on it. The new AMD processor "bulldozer" is coming out October 12th, so should I wait for that and get the best one for ~250 with the ASUS Crosshair IV (its like the intel one, (ASUS MAximus) but 100 bux less and for AMD, or do you think if I bought a cheap gigabyte server board and put two xenons or something on it would that still own it. I guess the best thing to do is wait, I already have a ton of Hard drives, 3TB solid states etc, but i just built a sick amd computer and I would like to make an actual server thats quiet and can crunch numbers I guess, what would you guys do. Considering its like 2 weeks away for the bulldozer and I could have an 8core that would be awesome, but at the same time cores and ghz means nothing because at 3.4ghz on this i7 4core I render faster then on my friends faster yet older i7, it's all about the architecture and intel basically rapes AMD in that department, so would two older and cheaper 4-core xenons I think I saw two decent 'lynnfield' type server intel processors on newegg for 250~ so that wouldn't be horrible, but then again I could get the nicer mobo (ASUS Crosshair) and pop an 8 core bulldozer and slightly oc it safely and just put linux on there and would that rape any other amd server for the pricfe?

IF TOO LONG:

1) Have a sick intel comp and want to build an AMD/or cheaper server. I already have most parts and have 6-700 to spend on the processors and mobo, if I get the BULLDOZER in 2 weeks I could still get watercooling etc, and it will be 8 cores and ive only had two 4 core intels (that owned) but 8 cores sound so fun, then again I could build a cheap dual core intel -4core server, but it would run at like 2.4ghz with 2 processors. Here we go Newegg.com - Intel Xeon X3450 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Server Processor BX80605X3450 [264] a piece, for 2.66ghz. Could I even OC something like that or I guess servers are better off left stable/stock. but would you just get that now and with what mobo? (1156 platform) or just build another desktop basically with the new bulldozer. Im basically using it as another workstation for adobe products, but im basically doing that on my intel now, so that or for webhosting/ftp/ hosting etc.

Pics of my current setup, its running 4.6ghz and vcore is at 1.35, but I can get 4.6 and turn vcore to 1.25 and it runs, and its only 35c with water cooling now, so I could easily crank it past 5.5 but I just don't know how, when I put the multiplier up (it goes to 59) if I go past 50 it just won't boot, and I have g.skill 16gigs of ram (DDR3 1866) would I need like 2133mhz ram or no, ive read many guides and tehy say you dont have to touch the ram until the end to get it stable, but yea some people on the OC site have like 6.7ghz and wtf how can they get it that high, I would like to push it to the edge once and I have it cool enough to prob max out at 6.5.. idk where to begin on that, anyways....

My i7-2600k set to 4.6 on the dinkiest stock heatsync, I have same settings but with water cooling its at 35c, in bios reads 28-31c.

the insides (I changed the fan on the left to blue cooler master to match the rest.

My mobo before putting the cooler fans on the ram, you can see the little circles where you can get OC readings, (voltage readings) and OC it from the MOBO physicially while its ON... as im saying, sickest mobo ever, imagine having the one at the top with two dual intel processors, would cost like 1500 for mobo/cpu alone but would be sick.

after ram cooling fans:

took this pic with my new canon video camera, refurbished from the factory, got it for 250, originally 900...

and the case/outside, I have at least 10 fans in this thing but got the best ones, quiet and move tons of air, coolermaster 120mm, but dissapointed when I found out that I basically could have this thing in a small cardboard box with 1 fan, since I think this 4.6 setting is basically as high as it will go , and will last for ever at 35c.

anyways let me know what you think about the server build/idea, thanks!
 
With the H100 you will not hit 5GHz let alone 6, which you are aiming for. The H100 is nowhere near enough as good as custom water cooling as I've seen so far in reviews/benchmarks. If you used liquid nitrogen or dry ice, then you might be able to hit 6GHz, but it probably won't be prime stable. It also depends on your chip, some overclock better than others.
 
If you don't know what your doing don't push so high so quickly. You need to OC gradually learning where the instabilies are coming from.

You should be able to run 5GHz with silly volts (> 1.45V). Forget any higher without going sub-zero.

As for the memory you can leave it alone as long as you are only OC'ing via the CPU multiplier.
 
It depends on your chip as well. Some overclock better than others. You said it yourself that you can't get it stable at 4.9 (you said it crashes). How will you get it to 5.5GHz then. Also, do you have hyperthreading on or off.

I'm sorry if I missed it, but what voltages do you use to get it to 4.6GHz. Anything above 1.38V is not considered safe.

EDIT: I used a guide to overclock my i7 2600k as it is the first processor I've overclocked. The guide is very useful and there are a number of changes other than the multiplier and voltages that you need to make in order to ensure that your overclock is stable.

The guide is HERE.
 
Of course I know I need to figure out the other things to make it stable, but as long as it is cool can I keep upping it, like could I do 1.7 to reach 6, lets say if I had it under 50c, hypthetically, would that be fine, or 2.0v as long as it was cool? look in the pix to see what my voltage was 1.33 for 4.6
 
Yeh you could use really high volts, but that would limit the lifespan of the CPU, it would probably stop working really quickly if you used anything over 1.5V 24/7. If you read that guide carefully it will tell you what things you need to change in order to get stable. Going from 4.6 - 5GHz plus will need a lot more volts and so the temps will rise very quickly. A lot of people will tell you that going over 75 C is not a good idea if you want to extend the lifespan of your CPU. If you just want to set a personal record than its fine as long as you don't use really high volts 24/7.
 
yea totally, I just want to get it up there and see it do it's thing, push it to the limit, then set it back. currently im just running it at 3.4 (stock) with XMP on 1866 and it is fast as hell.,

I also hear that using lower amount of memory may be bettter, and Ive been reading G.SKILL ram reviews (the high end stuff) and it seems like there are problembs with that and people are getting easier plug-and-play with Mushkin and other brands, corsair etc, I see the ram timings, and understand how one can raise/lower them, and would love to get 9-9-9-28 1T instead of 2T at least, but as soon as I try 1T OS crashes, so considering that would be lowering to 1 cycle, i'd have to raise the other ms's ?
 
I checked on newegg, where i ordered them, 9-9-9 28 2T, stock timings, GSKIL 1866 ddr3, so I have memtweak and can open that, here is a picture with XMP enabled. O damn now with XMP its 9-10-9-28...2T so even slower? What can I change to make this faster, I can do it in my OS but going from 2 to 1 = cmos reset time.

For my RAM I didn't use the XMP profile. I just set the timings via the bios. I used the specified timings. My RAM is rated at 1866MHz as well, but it wasn't stable with the provided timings, so I set the RAM to 1600MHz and stress tested to ensure that the modules were stable. The voltage was not changed and remained at 1.5V. I'm sure I would have to up the voltage to 1.65 or slightly lower to get the RAM stable at 1866MHz.

What voltage are you using for 1866MHz by the way? You may need to up the voltage in order to set the RAM to the stock timings of 9-9-9-28 2T.
 
You won't be able to run the memory at 1T unless you run the memory at a lower clock speed than it's rated for.

Typically the faster clock speed capable modules are just timed differently (read as timed loose) than the tighter timing lower frequency modules.
 
Well computer just crashed twice, first went into aida 64 and tried to click motherboard (other options worked, but something like system profile or mobo crashed my system) first time said 0x00000000101, rebooted and loaded this OS oc'ing software aisuiteII and it just crashed 0x000000F4, so i reset cmos, then did ez-oc4.6, in my mobo it says ram stock timing 9-10-9-28-2N-1 so... hm.

Here is the pic before bluescreen, everything stock (3.4-3.8turbo with XMP on),

aisuite.jpg


Now with oc on 4.6ghz and XMP. Havent done this with win7 now I wonder how stable this will be, and what can I do to the ram to lower / raise it, im gonna post this now then edit with pix so I dont have totype this 3 times. What do I lower/raise, do i have loose timings , is that good? (it was 1.508v ram voltage at stock oc with just XMP)

4_1.jpg


So weird it crashed in the beginning,. idk if i should run aida again, but yea now im oc'ing it and look at the temps above, thats low eh! but what do you think
 
more pix now, Oc'd and XMP'd , (guess the ram settings stay the same as XMP when at 3.4-3.8ghz

So now 4.6 (auto OC) and XMP. by the way C states set to No limit (mobo did this) and C1E set to auto, when I open settings in real temp it is unchecked, if i check it (or set it on in BIOS) then it will 'idle' at 1.6 and turbo up to 4.6, but right now hyperthread and all that stuff is on, but c1e is off so it is a constant 4.6 on all cores.

any suggestions?\

more detailed memory info, each stick slot 0-3 reads the same in CPU-z

meran.jpg


PCH PLL VOLTAGE reads 1.06 and NF200 voltage is 1.2505

EDITED^
 
I wonder if I should leave it like this (constant 4.6) temps arent going above 39c in realtemp, or let it idle at 1.6 and shoot up, but then it could have more voltage issues, yet it has worked in the past. this I assume is more stable since its just at one rate/voltage
 
I don't know much about these Intel processors or what they are capable of, but I have a feeling your instability is not your memory, I think your processor is over it's peak overclock at the given voltage.
 
It seems to me you have been a little miss lead with OC's and think that the people who rached these 6GHZ clocks were using stock cooling. In all reality im sure they were sub zero and pushing. These chips at there best with a good high dollar water cooling loop will do 5.3- 5.4 but thats pushing them really hard. Even then the owner would back it down to 4.8-4.9 for 24/7 use. My WC loop cost me almost 700 bucks and i didnt get but 5.1 out of this chip. Each chip is different. Each chip will do better then the next. It just depends on if you got a good batch of Cpus or not. But 6ghz i would invest in some DICE to get that high my friend
