Is The I7 1.65v Limit True?

To make you a quick idea: Vqpi=1.20v (min), Vdram=1.65-1.70v --> uncore safe Vqpi=1.50v (max safe), Vdram=1.95v-2.00v --> uncore safe Vqpi=1.20v (min), Vdram=1.90v --> uncore very stressed Last edited by Cliff Burton; You'll see it plainly enough when you get your board up and running and you get to key through the BIOS options. For example Corsair DDR3-1866 modules are validated at CPU VTT /uncore of 1.5+v. The final consideration of Intel's IMC is that in multi-socket systems, each CPU will have its own dedicated RAM pool and if a CPU needs data in another's memory allocation, it

Have any of you OC'd DDR3 and overvolted it???

I tend to stick by the manufacturer's recommendations, especially on such an expensive setup. if the chip itself can handle the speed, timing, and voltage. it isn't the voltage over 1.65v that fries the CPU.

In theory a 64-bit (8-byte) dual-channel DDR3 memory controller with 2GHz DDR3 could offer about 31.2GB/s (8 bytes times two channels times 2GHz divided by 1024 to get from MB/s to Intel performance guru François Piednoel was keen to stress that the CPU voltage must be kept within a 0.5V potential difference to memory. The time now is 05:15 PM. In light of daily workloads, a good DDR3-1866 C9 MHz kit will hit the curve on the right spot to remain cost effective.

at the end of the day.

that would suggest that 1866 @ 1.5v is the "current" grade A standard for ddr3. Results 1 to 19 of 19 Thread: Core i7 and DRAM voltage above 1.65v??! As folks who aren't aware of the uncore to vdimm 0.5v requirement, will try to keep CPU VTT at default values and raise vdimm beyond 1.65v.

The article I've linked to simply says 'CPU' but I can swear the intention was the uncore as that's the IMC.

Ahh yes, that's it, I remember that now! It does not mean it will function correctly at that v but will not damage. I searched but could not find that quote elsewhere, and your link shows no chips, 1.65v or otherwise, but Corsair Vengeance has been produced with Samsung K4B4G0846B HYK0 chips: The K4B4G0846B running any ram more than 1.55 volts will void the warranty.
