Overclocking RAM 1600 to 1866 MHZ

bubuie · Feb 14, 2018

CPU: i5 3470
M/B: MSI Z77a-G43
X.M.P Profile From Bios only got it up to 1600 MHZ
RAM : https://www.amazon.com/G-SKILL-RipjawsX-240-Pin-Desktop-F3-14900CL10D-16GBXL/dp/B006ZLJRO8

RAM only shows 1600 MHZ

What have you done in your bios, have you tried setting extreme memory profile (xmp) to enable?

bubuie · Feb 14, 2018

boju :

yes, I did turn on X.M.P profile, and it didnt went up , says 1600 MHZ

What does the bios read your memory at?

Xmp profile is there, can see that 1866. Can you set memory frequency manually?

boju :

XMP enabled , but sdhows only 1600 mhz, and i cant change higher than that? maybe my CPU does not support it ?

boju · Feb 14, 2018

Officially for 1:1 ratio your cpu supports upto 1600. Your motherboard supports higher if 22nm Ivy cpu is installed which your cpu is.

You'll have to try setting the frequency manually. In your bios, leave it on xmp profile so timings and voltage is set then look for dram frequency option. Can you choose 1866 there?

Boju,
I have set it on XMP profile , DRAM freq allows max to choose 1600 mhz anyways

boju · Feb 15, 2018

Probably a limitation then with the non k cpus that is not working with XMP enabled. What you'll have to do is disable xmp and force 1866 and manually input timings and voltage yourself. The values might already be set from xmp profile so check anyway.

Slots 2 & 4 are your primary two stick slots, im just checking.

Bios:

DRAM Frequency - 1866
XMP - Disabled
DRAM Timing Mode - Link

Advanced DRAM Configuration:
Command Rate - 2T
tCL - ##
tRCD - ##
tRP - ##
tRAS - ##

The ## is your memory timings, for example; As per specs of your memory 1866MHz CL10 (10-11-10-30)

tCL - 10
tRCD - 11
tRP - 10
tRAS - 30

Everything else in Advanced DRAM Configuration should be in AUTO

See if that gets you anywhere.

set DRAM Voltage - 1.50

Def, a locked CPU issue, nothing has changed still 800 MHZ in CPU-Z

Are you able to see 1866 in the dram freq drop list in the bios with xmp disabled?

bubuie · Feb 15, 2018

boju :

nope, can't only 1600 MHZ is max that can be selected

boju · Feb 15, 2018

Update your bios. Theres been memory compatibility fixes over a few releases since original, hppe it gives you added options to increase dram freq.

Your cpu shouldn't be limiting you as this person can raise it above 1600, i suspect its your motherboard.

Though G41 version but same z77a platform.

boju :

reflashed the BIOS And it's now working even CPU OC can be done, thanks

Your welcome

Is that with or without xmp? Just for my own peice of mind
