Yeah it might help to lower input volt a bit and test again or mabye just some more for the vcore. I have locked the uncore at 33x for the moment and memory 1333 just to rule out anything else beside the core. AIDA64 stress more if you just check CPU+FPU or only FPU for the hardest stressing. Perhaps great do stress each of them individually for the best result but it seem to work fine with both ticked.

If you get whea uncorrectable with 33x uncore, 1.15 ring then just add vcore (in 0.02 steps til it's gone)

well my vcore is already 1.38v for 45x ( 2 cores are at 44x).

with all cores 45x bsod on the 2nd loop of x264.


but now im on loop 18 and no errors. temps between 74-79.

im gonna test with aida after this. 4-5 hours is enough i guess.

my rams are at 1600 and cache 35x.

but i still dont get why 45x being hungry for that much vltage

"BSOD" doesn't help, what error? What's your 44x/43x stable?

bsod 124

44x / 1.31v
35x/ 1.15v
vccin 1.99
4-5 hours aida64 (all checked), 2 hours (only fpu), no bsod
2 X 4 pass x264. and 3-4 times cinebench. didnt test it in a game. (only dragon age origins lol)

Yes, those numbers are what I call "stable", at least for the stress testing I do.
I loop x264 for an hour or so, I run Prime 95 8K-10K-12K, 1344K fft's with >90% memory. Sometimes I run LinX.

Did x264 stress testing with following :
4.3Ghz
Vcore - 1.195V
Vrin-Stock
Vring-Stock
Uncore -35x

Posting x264 results here.
Results for x264.exe r2200
x264 Benchmark: 64-bit

Does this mean my 4.3@1.195V is stable ? Or should i stress again with XTU/IBT.

I just realized that due to the IMC that 1333 mhz is rated speed and anything past that is considered "OVERCLOCKED" is this true ? I was thinking backwards that if you buy ram at 1600mhz it should run at 1600 mhz. This is still considered overclocked with haswell?

45x multiplier with 1.38v
cache ratio 35x : 1.15v

vccin: 2.0v


rams are at 1600 with 1.51v


cant survive the 2nd pass at x264 but can run 3-4 hours on aida64. temps 80 ish

1.38 not being enough for 45x is killing me. i had to drop 2 cores to 44x and 2 goes on at 45x

whats your current voltages. i still dont get what im doing wrong
Yes.

I have Internal PLL Enabled

EPU Power Saving Mode Disabled

Enhanced speedstep technology disabled

turbo mode enabled

frequency tuning mode +

frequency tuning offset 6 %

thermal feedback disabled

cpu integrated vr fault management disabled

cpu integrated vr efficiency management high performance

power decay mode disabled

power saving level 1 threshold 0
level 2 0
level 3 0

additional turbo cpu core voltage 1.39

additional turbo cpu cache voltage 1.30

cpu system agent offset .39
cpu analog offset .39
cpu digital offset .39

cpu input voltage 2.1 (not comfortable with that...it was 1.98)

DRAM voltage 1.60

EIST Disabled

Turbo mode enabled

CPU C states Disabled

Also, I have a value of '8' for something I can't remember will look it up when I get home I think it's the "capability" something something header 8 is the maximum level -- I think that this is a drastic improvement in how far I can go

In addition, I'm dellidded and on an H100i stock fans

LLC??
well im also delidded and H100i 2 fans. ( CLU on die and cpu)

im gonna check the other parameters when i get home and match with yours.
