CPU Power phase control: Extreme

I think I may have spoke too soon though, as the cpu is throttling after about half an hour of prime blend :(

More tweaking needed.

I have 2 spectre pros in pull with the stock fans on the h100. I'm considering sending them back though and getting some NF-F12s or corsair SP120s for better performance.

morning guys i have bitfenix case dude and there fans are rubbish look good but performance is dreadful they dont push out anywhere near what they say tbh defo change them i changed all my spectre pros for typhoons

Half an hour into the blend test most likely the small fft's are being run.
The 8K and 12K tests are murder on the CPU as they are small enough to fit in the caches and exectute really fast.
That generates the most heat and load.
If you use a power meter the jump in power consumption when they run is alarming.

Selecting the small tests will bring on throttling much quicker if you are trying to eliminate that.
No need to spend ages on blend waiting for the small fft's to come round.

your really progressing well Orch good going m8

im gonna try my 5 ghz overclock now happy with 4.8 think i got them most i can so gonna write down settings and go for 5 ghz i added push pull to my 240 rad this morning so see how that helps temps on core also added a second 40mm fan over vrm so fingers crossed i hit 5 without to much heat will post progress soon

You still have some RAM tuning to do.
What are timings supposed to be for your RAM ?

Are they 9,9,9,24 1T ?

That could wait though as they are working OK now.
Also with those slack timings you can probably run them quite a bit faster.
Useful if you start messing with the FSB.

You can try for 4.8 but passing prime wont be so easy and things will get toasty.

24x200 1.4625V as a starter.
Leave all your other settings alone.

Yep according to the patriot site, 9-9-9-24.

I'm not fussed on passing prime tbh, I was only testing core temps, it's only used for gaming and browsing so as long as it stays stable doing that I'm good.

Ok so I'll leave timings for now, you think best to stick just using the multi instead of FSB?

Good luck hitting 5ghz! Look forward to seeing your benches!

Just ran Heaven 3.0 for the first time since the upgrade, used to hit 1095 score max with my fx4100, just scored 1435! Not a bad leap! Definitely unlocked a bottleneck there!
 
Use AIDA stability tests for testing then.
If that passes then try some games.

You could try higher FSB's but first you have to ascertain if your CPU can actually run stable at your desired clock speed (4.8)
Messing with the FSB at this stage will add more variables.

240x20 with NB and HT at 2400 would be a good start.
I would manually change the CPU NB volts to around 1.25 - 1.275 to keep the NB stable.
Select a RAM multi close to 1600.
Actually the 1333Mhz setting will be 1600 with a 240Mhz FSB.

Don't select all the tests unless you really want to test your Hard Drive and Video Card.

Just the CPU, Cache, FPU and RAM.

If you want to really warm up the CPU deselect everything except FPU test.
You can add and drop different tests without stopping as well which I like.
 
Looks a much nicer system to use compared with prime!

Ok so 4.6 seemed good, so I went with the suggested settings,

240fsb x 20
RAM adjusted to 15966
NB & HT 2400
Set NB to 1.256V

Blue screened on boot.

I've left the NB volts on manual but taken everything else back to standard, 24 x 200 and we're ok again.

Not sure which bit went wrong. I'm still on 1.4v vcore maybe that wasn't enough?

How do dervive anything sensible from a BSOD by the way?
 
Is any of this supposed to mean anything?

Try 24 x 200 first.
Standard NB speed.

1.4 is not enough I would say.
try 1.45

Your NB may not like running at 2400 without a larger voltage bump.

Anyhow see if your CPU can do 4.8 with reasonable voltage at the standard FSB speed before getting adventurous :)
 
I really wish these H80 fans didn't sound like a jet engine each time they startup, my boy is asleep on the sofa and each reboot is game of dare as to whether I wake him up :D
