Hi guys my spec is in my sig. I would like to ask for some overclocking advice, any help would be great! :D

I have currently gone from an old Thermaltake Shark (10 years old) case which had a meshed side to a Corsair Carbide Series 100R Silent Edition case. The reason for this is to allow for bigger graphics cards and also make things a bit more quiet due to my rig being in the front room. Only downside to the move is I now have no side vent. However the PSU is mounted at the bottom and this case has better air flow. Currently have one 120mm at the rear and one at the front, both at full speed!

During the rebuild of course everthing got cleaned and I used Kryonaut High Performance instead of my old skool choice of Artic Silver 5. My current cooler is a Cooler Master Hyper TX3. The new paste done wonders as my load temps are touching just over 70*c even in my new less vented case. They were touching 75's in the vented case! Good stuff!

My current overclock situation is as follows;

4.2Ghz @ 1.2v @ Max 72*c after 5 hours of Prime Small FFT's.

I have Voltage Response set to Fast.

LLC set to Medium and I get a slight vdroop down to 1.188v. If I set LLC to High it overvolts to 1.212v under load. If I set it to auto it droops to 1.152v. I guess the less vdroop I can get the better and overvolting is bad?

Any increase in voltage say to 1.250 it gets really hot when stess testing, early 80's. so I guess voltage increase is a no go?

I can get 4.3GHz stable @ 1.2v but don't see the point and back off to 4.2Ghz. Ive tried breifly at 1.3v for 4.5Ghz and get a crash.

I am guessing I have a dud chip in regards to most? Ive seen claims of 4.2Ghz at stock 1.145v?

So, my main question do I have LLC and Voltage response correctly? Also is there anything else I can do to get upto the 4.5Ghz mark?

Voltage hungry chip? :o


Edit:

I also forgot to mention if I set everything to auto, vcore to 1.2v and multiplier to 42 it vdroops down to 1.152 underload. Which did seem stable for a few days before messing with other settings today.

So in which case if I setup LLC correct then I should be 4.2Ghz stable at 1.152 which no vdroop? which makes things not so bad?

Any help or comment please guys? Much appreciate some input! :D

My current findings so far, are as follows;

Testing is all at 4.4Ghz at manual voltage, LLC set to high and Voltage Response set to fast.

1.230v = 1.236 at full load = Crashed when trying to start Prime95.
1.240v = 1.248 at full load = Crashed when trying to start Prime95.
1.250v = 1.260 at full load = Prime95 was running 30mins and I was browsing, Firefox crashed.
1.260v = 1.272 at full load = Testing using Prime95 now.

Temps are hitting 82/83's max.

Guess I have a power hungry chip?

If I set LLC to medium I get quite a lot of droop and unstable voltage.

I did try for 4.5Ghz at 1.300v under load and it crashed just loading the desktop. And I guess temps would have been waaay to high for my setup at 1.300v anyways....
 
you've done it right. just that final bit of testing and tweaking for 4.4 and leave it there cause its not wise to go higher than 85c under stress testing. normal use it will be at 70ish tops.
 
Multiplier 44 v cocre 1.3v then test forget 4.5ghz, If its stable and alls well then back down the vcore and test, same for every increment drop.

Your hitting high temps becasue of the air flow of the case, Can you add any more fans ?

Thanks for the replies guys, much appreciated!

I had to step up the voltage like you suggested. I have it set to 1.280v which gives me 1.296v under full load.

So far after 3 hours of Prime no errors or crashes.

More testing I reckon and see how it goes, if I can't get 4.4 under 1.3v then I may just back it off to 4.2Ghz.

At the moment ive got 2x basic Corsair fans, 120mm in the front and 120mm out the back. Gona upgrade to 2x 140mm's at the front and a better 120mm at the back soon. Keep the temps down a tad.


edit: is it safe for my LLC setting to overvolt on load? Or should I up the voltage and lower the LLC setting?

edit2: Swapped my settings up a bit now at 1.305v with Medium LLC. This gives me my magic 1.296 under full load. So it undervolts to the stable voltage rather than overvolts to it. Correct way to do it? All stable after 6 hours of Prime95. Max temp 88*c.

You should play a game it will show if everything is stable, i have had overclocks pass stress test and not fail untill i played a game then fail.
 
I will do, thankyou for the advice! Still stress testing now, all seems sweet. Just a little hot...

I just ordered myself some cooling upgrades :D

Replacing my "Coolermaster TX3 92mm" cooler with a "Coolermaster 212X 120mm" cooler. My rear standard cheap 120mm exhaust fan with a "Corsair AF120" and my standard cheap 120mm inlet fan with 2x Corsair SP140's.

So should now have a lot more air going into the case, a lot more air going out and a bigger heatsink and fan. If I can knock the temps down I will be well happy.

Thankyou for the reply!

I can't get mine at 4.3ghz without over 1.35v, by which time I am so close to throttling.

Damn and I thought mine was bad! What bios settings did you use? I turned all my energry saving settings off, manual voltage and voltage response fast.

The 212X cooler did fit in my case. Only due to the side panel shape though, very very tight! It has seemed to knock about 10*c off my CPU temps, with combination of the other upgraded fans.

Anybody comfirm max safe voltage? Ive read 1.3, 1.4 and even 1.5?
 
1.35 would be max on air cooling.....

is your ram set to xmp??? if it is turn it down a little. if the IMC if your chip is below standard(this is normal) you may find it unstable and having to pump loads of voltage into the chip. set ram to 1600Mhz and retest

I wouldn't worry about max voltage only the temps, if you were under water you'd go a lot further the main thing is core and VRM temps. I almost had 4.3ghz but it'd crash playing fallout 3 so I just backed down and lowered the volts + clock.

a vccio bump would fix imc instability. vcore wont help.
if there are imc problems, it will pass 24hrs of small ftt's, but fail with custom large 4096k ftt's using max available ram

I do have XMP enabled, which clocks my ram at 2133MHz. Would I getting a better OC, ie have to put less volts through with XMP turned off? Aslo much much on the memory side by turning off XMP?

I guess each CPU is different....I don't think I can get much higher anyways tbf since my temps are quite high. Although now I seem to be getting 80*c max temp under load after a few hours of Prime. I was hitting 88/90 before my cooler and fan upgrade. So I may try for 4.5GHz, never know I maybe nearly there...

So may aswel keep ram at XMP?
 
Guys just a recap, if anybody is still there to lend a hand?

I have been having issues with my CPU clock dropping to 257Mhz while running 3DMark's stress test. This shows up in 3DMark and in HWMonitor.

I have been running 4.4Ghz @ 1.305v and LLC set to Med for ages now. This gives me 1.296v under full load.

I get no WHEA errors, no blue screens etc. Just both programs logging the clock drop.

So I cleared my CMOS and tried auto settings/voltage. It gives me a auto voltage under load of 1.320v which is too high for me to tame temp wise. However could be what my chips needs to be 100% stable?

So my next try was 4.2Ghz auto voltage. It volts upto 1.200v and drops to 1.188 under full load. I get zero WHEA errors and no drop in clocks when stressing.

Judging my my prevous settings 1.200v and 1.188v under load seems about right for 4.2Ghz I guess? I does seem to be a lot more stable than before.

Any ideas? I left it all on auto atm, with a multi of 42 and all turbo states and save states off. Gettings max temps now of 71*c while running prime for an hour.

Any help much appreciated!
 
Dont overclock with auto on m8, it can apply some silly voltages, keep it to normal with an offset or manual.

As for it dropping to 257mhz that sounds like HWinfo just messing up its readings, i get false readings when bench testing quite often when the computer is fully stressed it cant keep the HWmonitor updated properly. I dont think CPUs even go that low tbh. Are you noticing a considerable drop in FPS when it says your getting 200 mhz cpu speed?
