Hello everybody! Long time no posting since I was kinda disconnected from the OC world and assembling parts, though that ... the itch never dies so here I am. After a long search these last weeks and see benchmarks/reviews I saw no real point "yet" to change my motherboard, CPU or RAM. I certainly did with the GPU and monitor, switched from a HD6850 to a GTX770 and got an LG29UM65.
Thing is I'm quite happy with the result, but I want a lil bit of extra juice. My 2500K was running 4.1GHz since almost first day with stock voltages (1.260V idle - 1.248V load) and to barely match my speeds with the new architecture I know I had to push it further. Right now is at 4.2GHz stabilized but i'm hitting a wall and certainly IDK if the CPU needs more VCore or more tuning in other stuff.
Here are the results:
4.2GHz (42x100)
VCore: 1.296V idle - 1.284V load - 1.272V super-hard load (with IBT or Large-FFTs at some points)
VTT: 1.125V (read in some places 1.075V is intel max but can be pushed till 1.2V)
VccSA: 0.975V (set at intel Max)
PLL: 1.840V
DRAM: 1.655V
DRAM Performance: Extreme
Turbo: Disabled (running always at 42x)
C-States: Disabled
CPU PLL Overvolt: Disabled
Tests passed
Prime95 (Small FFTs) - 1h
Prime95 (Large FFTs) - 1h30min
Prime95 (Blend Test) - 1h + 1h30min
Linpack (AVX Enabled - 90% memory) - 1h + 1h30min
OCCT (Big quantity of data) - 1h + 1h30min
AIDA64 (CPU + FPU + Cache + RAM) - 1h
OCCT GPU (2560x1080 - Check Error - 2048MB) - 20min
3DMark11 - 5 runs
Normal desktop stuff (browsing, watching videos, listening music)
Gaming Assetto Corsa for 3 hours
However, for getting 4.3GHz i'm not able to stabilize it on Large-FFTs or OCCT CPU neither pushing 1.89V at PLL and/or nearly 1.2V to VTT ... and with 1.308V on load at the cores. So, what should I do, trying to push a lil bit more CPU VCore? Try to adjust VTT and PLL to a "sweet" spot? Decrease RAM performance to a lower value? I'm kinda lost.
Most "amazing" thing is it was able to pass LinPack and SmallFFTs with 1.296V but Blend, Large-FFTs or OCCT CPU are not even wanting to do with 1.308V and all the other voltages (VTT & PLL) raised with the usual 0x124 BSOD. Is it normal that can do 4.2GHz totally stable at 1.284V and having to up till 1.32V maybe to get 4.3GHz? Sounds a lil bit strange but I'm waiting for your answers.
Thanks in advance.
PS: You can check my specs to get more info
