O.C 2700k

[methix0r]

i got a new computer core i7 2700k p8z68-v/gen 3 mobo naxt havik 140 cpu cooler i should have got a 3pin to 4pin for the fans one of then is runnig at 1300rpm and makeing annoying sound which is 100rpm over its max speed weird?


anyway i asked them to o.c it to 4.0ghz and when i got home i went into bios and saw tey jsut put the pcie blck thing to 103 which gave it a 3.6/4.0 turbo i asked for 2133mhz ram and the ram was ste to 1921mhz with the pcie blck at 103 is it safe what they have done? and is the memory right?

i loaded optimized defaults and ptu it back to 3.5 3.9 and the ram auto set to 1866mhz the temps where pritty much the same with it at 3.5/3.6 just want ot make shure what they did is ok and the ram speed and that is correct before i put it back to what they set it to everything is mostly set to auto in the bios when it was at pcie/blck at 103 liek ram auto elected to 1921mhz the turbo option was set to auto as well

Hi

I'd personally set the BLCK to 100, set the CPU multi to 40 and try a Vcore of about 1.2V to start with (test stability and monitor the temps!)

Then set your RAM to its rated speed/timings/voltage.

With regards to your Fan running faster than its rated for, technically its not as they allow for a 10% leeway (E.G 1080RPM - 1320RPM) providing your fan is rated for 1200RPM

I would set the BLCK to 100. Everything I've read on the matter says, don't alter this from 100.
Secondly the ram speed isn't very important, as benchmarks show 1600 vs 2133 has little in the way of measurables benefits.
(Side Note: My Ram is Running at 2133, So if your system will run with your RAM set to that, GO for it, but be warned Intel Voids warranties on their processor is they know your RAM is clocked over 1600)
Now I would set my CPU Voltage to 1.265 45x Multiplier, and see if you boot, and can keep Prime95/RealTemps(2 Programs you NEED)

If your booting, and Benching and staying under 72c I would keep those settings. At that voltage I dont see it getting too hot. If you don't boot/bench or you crash bump your voltage up to 1.285-1.300 monitor your temps and repeat.

Make sure your RAM is at the proper voltage. Sandybridge systems don't like undervoltage at all.

i pritty shure i asked for gskill 2133mhz ram so what should i put the ram at when i o.c it what is marked on the label?

 

[Rustyy117]

If your RAM has XMP profiles you should be able to check what your RAM is rated for using CPU-Z under the SPD tab, or alternatively just look at the sticker on the side of the RAM stick(s).

 

[methix0r]

cant take the ram out some weird ass things that lock the ram in on y mobo and i just took the side panel of and the naxt fan is makeing a loud noise think i am jsut gonna get another cpu fan like hr2-macho

 

[methix0r]

this is what it says in cpu-z for ram ddr3 8192 dram frequency 936.6 FSBRAM 1:7
CL 9.0 clocks TRCS 11 clocks TRP 10 clocks TRAS 28 clocks now i no the rma i got is g skill 2x4gb and whn i looked in the case withotu removing ram i saw pc 1700 on the sticker

 

[Rustyy117]

Did you look at the SPD tab aswell as the memory tab?

If you saw PC 17000 then its definitely DDR3 2133, and it seems like its running at 1873.2Mhz @ 9-11-10-28.

If you can't get the right angle to see all of the sticker, maybe try taking a picture of it with your phone or a camera?

Though its not that important, like was said previously RAM speed above 1600mhz doesn't effect performance much.

http://www.pccasegear.com/index.php?main_page=product_info&cPath=186_912&products_id=17938 this is my ramm does it tell me there what to put it at?

 

[methix0r]

PC3-12800 F31700CL9 that is what it says in spd

 

[Rustyy117]

It says 9-11-10-28-2N @1.65V

So I would say that your current timings are correct, but you'll want to set your RAM speed to 2133Mhz and make sure the voltage is at 1.65V

 

[bearclaw99]

Set everything to defaults and then simply up the multiplier to 40. There is no sense having the BCLK altered since your CPU has an unlocked multiplier, and messing with the BCLK on Sandy Bridge can destabilize your processor easily

 

[methix0r]

i pout everything to default put multiplier to 40 turned of speed step turned of turbo mode put volt to cpu at 1.2 now i go run prime 95 test it if all good then i go to put ram to 2133 and put the rame timings for it in did did miss anything anything els ei have to turn on or of in the bios c1e crap or w/e?

 

[methix0r]

should i turn hyper threading of to or not not im only overclocking to 4.0 so i put multipler to 40

 

[methix0r]

something is wrong i set cpu multiplier to 4.0 when i boot into windows its still like speed step is enable and the cpu is at 1,6 and goep to 3.5 wth? it not at 4gz

 

[dadof1hunter]

G.skill 9-11-10-28 2133Mhz, 1.65v Same Ram as me... I had to manually set my ramp to those settings, when I used the auto setting it put it at 1866mhz.

So that's your RAM settings. OC your CPU, and Enjoy.

Leave Speed Step enabled. 1.6 is the power saving mode... When you bench it should go up...

Check your settings

BLK: 100
PPL Over Volt: Enabled
All Cores
Multiplier 45
EPU Power Saver: Disabled
CPU Spread Spectrum: Disabled

 

[Rustyy117]

Go back into the BIOS and for now turn off C states (C1E ETC...) make sure Turbo is enabled and that your multi for all cores is 40, leave hyper-threading on.

 

[methix0r]

do i need to have turbo enable to 4.0ghz o what>

 

[Rustyy117]

Yes.

 

[methix0r]

ok the c1 *** i got is cpu c1e cpu c3 report cpu c6 report which one do i turn of

 

[methix0r]

did that booted up open cpu-z and it is at 1600mhz again still liek speed step is turned on....

 

[methix0r]

i set the cpu ratio to 40 yet when i go into the bios it says cpu ratio 35

 

[dadof1hunter]

ok the c1 *** i got is cpu c1e cpu c3 report cpu c6 report which one do i turn of

Disable all 3...

 

[dadof1hunter]

did that booted up open cpu-z and it is at 1600mhz again still liek speed step is turned on....

That's right, and it won't go up to full untill you Run PRIME95, and Stress it... which is fine...

 

[dadof1hunter]

i set the cpu ratio to 40 yet when i go into the bios it says cpu ratio 35

Wait a second... I think your getting CPU Ratio Confused...This is NOT THE MULTIPLIER
