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.

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).

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

this is what it says in cpu-z for ram ddr3 8192 dram frequency 936.6 FSB:D RAM 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

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.

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

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

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?

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

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.

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

Theres MULTIPLE places to disable power saving features as I recall.. Leave them ON... These are not bad features and you'll be able to OC just fine.

i am not getting ratio confused with multiplier that is the only option to put the x40 in in my bios is the cpu ratio , and i notice the core voltage is dropping to 1.192 and going back to 1.200 in cpu-z i set it to 1.2 in bios so far in prime 95 3 cores are udner 60 dreggrees and one is at 64-65 degrees. do i turn any of those c states back on l8r or what?

multiplier 45 i dont want to do a 4.5ghz o.c only 4-4.2 can i leave volt at 1.2 if i want to do 4.2 or should i put it up to like 1.22 1.25? ad if i put speed step on wont it change the volts or only change the volts when cpu speed up?


i also have all the 3 c states disabled in the bios atm do i turn these back on at any point


im a newbie so is it ok to set it manually to 1.2volts and have speed step on and it be at 1600ghz ? 1.2volts while the processor is at 1.6ghz if thats ok then i say o.c is fine at 4.2 with ram at 2133 speed step on

I have 4.5 on 1.265, My temps TOP out at 62c. I didnt just PICK a speed... I watched my temps after HOURS of Prime95 to see what my processor could do with Given Volts/Temps... If you can get 4.5 off 1.265 I think you go for it... Othwerwise your getting the lower speed with the same temps...

Leave C States Disabled is ok... Some people turn them off... Mine are ON. Trial and Era... If they cause problems turn them back off.

SpeedStep Shouldn't change your voltages.

But yeah 1600 is the default idl, its fine... and good that it does that.. otherwise your PC is a Energy Hog.

Try your Voltage at 1.2, but thats kinda low... if it works stable for 24 hours of Prime GOod.. if not bump it up and try again.

i have set all the settings states in this thread and all options i need to enable or disable i ran the prime 95 fior about id say 24 hours total now no erros no problems volt is stil at 1.2 i coudl maybe lower it to 1.18 or 1.19 and it wil be stable but is there anything else i need to enable or disable in the bios that is not lsited here that should be changed
