CPU capability list - Maximum DRAM Frequency

[GSKILL TECH]

When building a system with a specific target in mind, special hardware may be necessary to achieve that goal. By having an idea of what your CPU is capable of, you can build the system around that. Here is a list of each CPU's typical capability. Depending on your luck and OC ability, your CPU may be capable of higher, but this list is for average results. With a compatible motherboard using the G.Skill QVL List, you can expect high performance results with the proper combination of hardware.

Please feel free to post your own personal results especially when using non-K series CPUs; non-K series CPUs are not designed for overclocking, so we usually do not work with those particular models and will have limited data.


These ratings are for 1 DIMM per Channel.

ie. if using full slots, DRAM Frequency may need to be lowered; with certain motherboards, you can increase CPU memory controller Voltage to force the system to support more modules or a higher DRAM Frequency.

3570K: Tested four of those, all could do DDR3-2400 and two had no issues with DDR3-2666 either, on ASUS ROG Maximus V Extreme (Z77).

3770K: My 3770K has no issues with DDR3-2800, on Gigabyte Z77X-UP5 TH.

4770K/4790K: Never had one that failed to reach DDR3-2800 on a decent MB, Gigabyte Z87X-OC / Z97X-SOC Force in my case. From quick tests with single sided MFR my current 4790K maxed out around DDR3-3400, but it might also have been the weak-sauce retail memory =)

G3258: Hit DDR3-2800 with Samsung and Hynix based TridentX on Gigabyte Z97X-SOC Force (did not test higher).

6700K: Did max out any memory i threw at it so no final judgement yet, but DDR4-3733 seems pretty safe on ASUS ROG Maximus VIII Gene (Z170). If you are using iGFX you might need to keep it lower depending on VCCSA/VCCIO needed, because of black-out issues with the onboard HDMI when those voltages hit certain thresholds.

For the i7-7700K you list 3200.

I think I am doing better - I have Gigabyte Aorus Gaming 7 mobo with an i7-7700K clocked to 5GHz.


I have installed the 3866 Trident Z RGB and with Gigabyte bios vF3 XMP profile enabled. The system boots windows 10 and runs rock solid stable. (Gigabyte have this memory on their list )

CPU-Z software reports the memory frequency 2*1864 = 3728MHz

Thanks for the info. Good to hear! The maximum results vary with each CPU; the list is a guideline of what you can expect to work with any CPU of that model.

This needs a update :] I see no i9 in this list :]

10600K, SA/IO stable voltages:
4000 + subs tightened - 1.20/1.15V
4133 + subs tightened - 1.25/1.20V
4200 primary only - 1.25/1.10V
4266 primary only - 1.30/1.10V
4400 primary only - 1.45V/1.30V, testing only, not recommended for 24/7

These voltages are with added +0.05V for 24/7, otherwise you can have unexpected BSODs. I noticed required minimum voltage changed day by day, but I didn't notice more than 0.05V fluctuation.
4266 is borderline, but 4200 should be no problem for 10600K.

10500 and 10600 have worse IMC than 10900, they say max is 4533 MHz. 10700 is probably somewhere in the middle.

10600K @ 4.9 on air an 5.1 on water
G.skill 4000MHZ cl 17-17-17-39 1.35v @ 4300MHZ cl 16-16-16-35 1.5v no xmp it is whit sub timing ,VA/SA 1,35v

would like to test some 5066 mhz on my sys, would not think it should be a problem
