Guyz, I have a 2x KVR 1333mhx 4gb ddr3, no heatsink. I would like to know if I am able to OC it to 1600mhz or even 2000mhz? And shud I set the timing as auto?

Depend on luck
I have 4x2GB KVR 1333mhz that can run 1800mhz or so

owh.. ok. So, let me get it straight. So, to overclock, I just need to go into bios and then change "AI Overclock Tuner" From "Auto" to "XMB". Then, change the DRAM Frequency to the desired frequency. Anything else that's needed to be done?

Best if you can show us your PC specs in more details because different platform has different voltage terms, OC capability due Integrated Mem Controller aka IMC strength, as well as limitation of CPU/chipset. A Sandy Bridge processor is limited up to 2300MHz only, Ivy Bridge can hit 3000MHz+ highly depends on how strong is your chip's IMC and RAM ICs.

Basically, mem overclocking either frequency increment or timing tightening requires a bump on vdimm (RAM voltage), VTT aka VCCIO, IMC aka VCCSA. When you are increasing the frequency say 1333 to 1600, you might have to relax the timing ie 9-11-9 to 11-11-11 etc to compensate for lower vdimm and related volts. That is for primary timings, playing with secondary and tertiary timings requires a more advanced OC skill and patience.

Ok, thank you. Here's the specs that im using:

Motherboard: ASUS P8Z77-V LX (LGA1155)
CPU: Intel I5-2400 (6M Cache, up to 3.40 GHz)
GPU: ATI Radeon HD6790 (1GB GDDR5 256-bit)
Ram: 2x 4GB KVR 1333mhz
PSU: Xigmatek 500W NRP-VC503

buy this kvr and play with it can go like this just adjust ram devider

Here is my overclocked ram...DDR3 2200MHZ @ 1.5205V

cannot do with lower voltage?

My another shot. I can't boot with 2400MHZ no matter what timings and voltages...MSI boards aren't good at RAM OCing.

All psc cip can overclock ke

I'm not sure with value modules but all the performance kits can OC very well on Ivy Bridge.
My experience with PSC kits.

G.Skill Pi 2200C7 2X2GB:


G.Skill RipjawsX 2200C7 2X2GB:

i have few questions,

-what is PSC kit?
-let say the spec of the kit says DDr3-2200, will it auto clock to 2200 out of the box or i need to set it in the bios to make it run 2200?

any more samsung green ram avail? where to get it ya?

PSC stands for Powerchip Semiconductor Corporation, a RAM IC maker.
The Ivy will boot at either 1333 or 1600 at default, according to the highest SPD profile of the module and you would need to set it manually to 2200 in BIOS or rely on XMP profile.

Looks like Samsung Green is discontinued everywhere already. Newegg, eBay, amazon, BHPhoto are no longer selling this kit.

Latest OC for 4.5Ghz @ 1.28Vcore

Seems stable for 5 hours plus on prime.



Running on xspc raystorm kit. Would the temp abnormal?

Wrong thread dude. But it looks normal for undelidded Ivy, as long as it is under TJmax of 105C than you should be fine.

KVR 1333 C9 2 X 2GB 1.5v, it's a highly binned PSC X kit so please don't go buy bluntly this KVR you won't find this so easily.



2400 7-11-8-28-1T @ 1.685v


2500 8-12-8-28-1T @ 1.83v

hmm whats with everybody running 2t on ivy.

hmm wonder when the msi 3k gaming ram will be coming out.
