Nice kit that deserves an beautiful outfit.
Buy heatspreaders for it and keep it!  biggrin.gif

I wish too bro, but pokai liao so tryin to off load it. Its just like another pair of mfr/afr which is okayish. One thing i noticed is d kit doesnt seem to like voltage. 1.4 vdimm doesnt really help to push oc headroom. 3333 is juat quick bemchable. sad.gif

Confirmed able to do better under ya hands bro. biggrin.gif

Interesting video from Mindblank again.
He sure has a very good RAM kit coupled with a strong IMC in the CPU.
But one thing he lacks is that stress test has not been done to confirm its stability.
3466 C14 is not easy with my current hardware. It can run stably in one test but failed in another test, not 100% stable.
Suspect is weak IMC seeing at the high SOC that my CPU required. sad.gif

Mine was pumped 1.5V too, not stable as well. confused.gif

I put up to 1.45v, tpu memtest can pass hrs but p95 blend (15gb allocation) failed almost instantly. Loosened timing, more vdimm/vsoc also not helpin. I stop at 3333, on k7. Hopefully better on on tomahawk (fat hope i know tongue.gif).

I'm running that 3466 Vengeance RGB kit rock-stable for a month now at CL16-18-18-36-55 (exactly as per the XMP/DOHP). DOHP profile 3466 doesn't work, I had to put timings and a bunch of sub-timings (tRRD_S, tRRD-L, tRFC1, tRFC2, tRFC4, tFAW, tCCD-L) manually, give it 1.4v, vboot also 1.4v, vsoc 1.1. Now after watching Mindblank's video, I'm very enticed to try CL14. You shared your CL14 timings with that 3466 kit before right? I'll try to replicate it and see if I get more stable result with my 1700's IMC.

Don't use TPU Memtest as it's not stressful.
Need the paid HCl Memtest Pro, which is usually used by RAM manufacturers.

None of my B-die RAM will run stable at 3466 16-18-18-36-55.
Your vSOC at 1.1V, means your CPU has a strong IMC. Mine needs 1.20V+.
Nope, I did not share my 3466 C14 here as it's not stable. SPi passed but HCl Memtest failed.
