Turning off turbo in bios locks cpu to 3.5ghz for me, so no. Leave it auto

Played another round of BF3, no crashes so far, fingers crossed.

Believe it or not, actually bumped up the igpu multi to 1400mhz, I noticed it was slightly more playable at 1080p lol.

Since I don't have a gpu figured I would finally get down to business on overclocking the cpu. Currently testing 4.8 ghz at 2.192 VCCIN, 1.39 vcore. Seems to be ok in xtu utility for now, got a bsod about 15 min ago so increased vcore. Temps are crazy low since I added the ex480 rad. Max core temp hit 81, they generally hover around low to mid 70's.

Water cooling loop has 3 radiators and no gpu so should cool good lol. 1 480, 1 360, and 1 120 tongue.gif

Edit: damnit spoke too soon, another BSOD. Going to 2.2 vccin...

When I start tunning up the uncore, and if have to increase that voltage, 1.9v will still be enough?

Theoretically it's enough, but if you BSOD with 'clock watch dog' error, then you'd need to be bump it a little higher.

Yes i passend 20 runs x264
@Ali Man
Uncore 43x @ 1,2v (thats msut be Stable because before i got 44x at the same voltage game stabile) 43x is synthetic stable so uncore shouldnt be my Problem

Well that same BSOD does refer to an unstable uncore, so you'd be better off keep it at x40 while overclocking the core.

What vcore/vrin were you on for x47 stable?

Drop it down along with vring till core is stable.

There's no way for it not to be stable at x40 with 1.200V, so I stick to my sentence.

I will also just leave turbo alone, it doesn't have any affect on how you overclock and if you overclock higher than the turbo boost anyway, the oc ratio will be the set number it will run at anyway.

What temp are you getting with your cooling setup and what cooling did you have before? I am also trying to figure if going custom is worth it, if I only get 5c or lower than it isn't worth it but if I can get 10c or more then it is something I would do.

Maybe so but it can have a knock on effect with vrin. Iif it was stable with 1.2v@x43 then 1.2v@x40 is overvolting for that multi. The whole idea of dropping uncore down (& RAM) is to isolate them whilst OC'ing core. As core OC increases, so can the required vring (and possibly vrin) for uncore, never mind SA/IOA/IOD.

Each to their own then.thumb.gif

I dropped 20deg+ by delidding and temps are near enough capped at 70deg under water regardless of application.

For4.7 stable, iI needed 1.365 on vcore, 2.0 vccin. As for cooling, my setup is complete overkill at least for now. Total of 960mm of rad space... But I have plans to have 2 R9 290x maybe 3. I will say, I just got this EX480 and I'm very impressed with its quality. The price is much lower than equivalent rads and I'm very pleased with it.

I may try for 4.9 as I still have some room thermally.

I never really tested my temps before. At 1.35 vcore running one 360mm radiator, load temps were mid 70's.
