Skuldarin - if you are dropping sticks at certain speeds, use BIOS 0003 and set your tRL values, this may help you.

I've had my 980x for a week or so now, and have spent quite a fair amount of time getting it stable at various clocks, and error free in linx.

Tonight, I hit 4.4Ghz (23 x 192), QPI 3447, Uncore 3830, memory 2:10 @ 1914.

However, I had to do this with about 1.46vcore. QPI didn't have much bearing on things, only upping the vcore gave me error free results with linx passes. If the vcore was around 1.4 - 1.44 it would always error out on the first or 2nd pass, yet the system never bluescreened.

I have had the system running 4.5Ghz - but this is with Linx errors, and also the 1.5x memory divider.

My CPU is watercooled, and temps with my current voltage did get into the mid 80's, which is more than I would like to see regularly. I need to find a way to bring down the vcore yet still maintain a decent overclock. Perhaps I just got a 980x that needs voltage to pull the numbers.

I've tried many combinations of Uncore and memory speeds, bclk and multiliers, yet it always comes down to the vcore setting to attain stability. I guess this is a given, but I see many of you guys hitting similar clocks with lower vcore.

I'm using G-skill Tridents, perhaps there is better memory out there that would allow me to hold a higher overclock with less vcore. Open to suggestions!

Tuning CPU PLL(which also tunes QPI PLL behind the scenes) is the only thing I've found that has allowed me to lower vCore while maintaining my overclock. Sweet spots I've seen always seem to be on whole or half step: eg:
1.2
1.25
1.3
1.35
1.45
1.55
1.6

Those are the values I've seen people working with. Personally, 1.55 -> 1.2 -> 1.25 are the best, in that order.

@Toritechie

What is your VTT? UnCore at 3830MHz might be your problem, if VTT is set too low.
I highly doubt that your CPU is that bad. Might be that you are compensating lack of VTT with high vCore.

Hey don,

My VTT is 1.41 at the moment, i'll try increasing it and dropping my Vcore later on ... will let u know

Hi guys!

I just got a 990x last week and trying hard to find a 24/7 OC for it.
What do you think is the max vcore for 24/7, if i only use it for gaming? Im watercooled with the Swiftech h20-320 kit, and NB waterblock also from swiftech. Currently im stuck at 4.5ghz, 1.39 vcore in bios, in cpu-z it reads 1.376 in idle and from 1.343 to 1.349 in load under prime95, cpu pll at 1.31v, all that with LLC at 50%. I have the rampage III extreme board, of course. I would like to use it in the primary rig for at least 3 years, so I would like to find a sweetspot between safe vcore and performance, something that can give it a run for the money but not devastate it (i know will probably sound stupid to you guys, sorry). Batch nuber of cpu is 3045A709 . Im a little dissapointed with this CPU, i thought according to info on the web prior to the release, I could have a higher 24/7.

Thanks guys, please give me some advice!

Wow 4v, insane

haha i know i mistyped there yes, 4v, i use compressed super LN2 and turned my 980 into a super conductor and power it with a nuclear reactor.

Skuldarin - if you are dropping sticks at certain speeds, use BIOS 0003 and set your tRL values, this may help you.

i already loaded 0003 actually. at the moment i've only been trying to get 4.5 stable again with it, i haven't done much mem tweaking yet. but so far i lowered my rTL's to 60, 61 and 62 down from 58, 58 and 60 (stock) but that's about it.
