1333mhz with 1600mhz Memory. Will It Work?

Prahsper · Jan 27, 2015

Hello,
I have the Asus P8Z68-V LE running with 2 Crucial Ballistix Sport 4GB DDR3 1333MHz PC3-12800 1.5V OC'd at 1606mhz in bios.
DRAM frequency @799.9mhz
FSB

RAM 1:6
CAS# 9.0 clocks
RAS to CAS# 9 blocks
RAS# Precharge 9 blocks
Cycle time 24 blocks
Command rate 2T
All according to the program CPU-Z

I mistakenly purchased 2 Crucial Ballistix Sport 2GB DDR3 1600MHz PC3-12800 1.5V BLS2G3D1609DS1S00 1600. Can't exchange them so I am stuck with them.
Is it possible to get these four memory sticks to work well and together with this motherboard?
When I first added the 2x2gb 1600 sticks with the 2x4gb 1333 sticks the computer just kept cutting on and off without reaching the bios. My processor is an Intel Core i5-2400 3.10ghz
Are there certain settings to set in the bios for all four to work together or is this a no-go? Thanks.

Maybe, no way of telling without trying, even mixing packs of the same exact model can be problematic. If you try and have problems give me a shout, often problems can be eliminated with voltage and/or timing changes

VicVega1 · Jan 27, 2015

Perhaps your overclock is the problem? Try setting it back to default, so that your mobo will run those new sticks in 1333 automaticly and then oc them all to 1600, or just leave at 1333 and maybe tighten the timings.

Tradesman1 :

OK....I tested the new memory in both channel sets. Two at a time and the new mem worked well in the blue slots and the brown slots by themselves. I added the old mem to the blue slots and new mem in brown. PC won't boot up. Just beeps once and keeps cutting on then off over and over. Never reaching the bios. MemOK button did nothing to help. Gives the same results. On and off. Cut the power and I switched the sticks-old mem in brown and new mem in blue and still get the same results.
I also, at one point defaulted the settings for the new memory to run at 1333mhz. Rebooted and then shut down. Then added the old memory, doubled checked to make sure it is still set to run at 1333 but the same outcome occurs. Comes one, beeps once and shuts off. Over and over until I cut the power off.
What should the voltage and/or timing changes be set for?

I tried to add screenshots of my bios setting but it doesn't seem to stick in the post.

That is strange. Meaning - normally (or in my experience) if RAM sticks wouldn't work together you can normally boot your PC, it's just that one or more sticks is disabled or invisible for the system. I had similar symptoms with a bad OC once, so perhaps it's your overclock that's causing this. Set everything to auto and let the mobo do its work.
Also there is a specific order to put RAM sticks in, be sure to follow it.

Prahsper · Jan 27, 2015

VicVega1 :

OK...I will work on shutting off the OC and see what happens. Also, no memory is missing or invisible. What you see in the images are just the 2x4GB showing.

Also set the bclk (pcie frequency) to 100,going over that means an overclock anyway.The memory will run faster because of this being at 103 at the moment.
Maybe try XMP after this again.

Prahsper · Jan 27, 2015

Vic 40 :

Unable to change bclk to 100. First it only shows when overclock tuner is set to 'manual'. When I change bclk to 100 and move from it, it automatically goes back to 103.0. Also now in 'manual' the dram changes automatically from 1333 to 1372. Drop down option to change that back to 1333 is gone. Unable to change the voltage from 1.65 to 1.50. Everything sets back to what I had set normally when I put the tuner back to auto. Dram back to 1333, voltage ca be set to 1.50 but bclk option does not show.

OK...better yet....let's make this as simple as possible...How do I turn off the overclock feature in the bios of this motherboard? That's what i want to do but don't see where to go to turn it off.

VicVega1 · Jan 28, 2015

Prahsper :

How did you overclock it in the first place?

Fastest way would be to find an option like "restore default settings". It's usually on the home page of every BIOS setup.

Prahsper · Jan 28, 2015

VicVega1 :

I didn't. This board came with the Auto-Overclock feature. Preset for those unfamiliar with working overclock settings. Restore to defaults wasn't enough to turn it off. Still getting [Overclock Failed. Press F1.] message after post bootup when all four dimms are installed. When I take the 2 new dimms out. It boots fine. It only does this when all four are in.

VicVega1 · Jan 28, 2015

Prahsper :

So there you have it. Overclock is the reason. If by default it was set to automatically overclock, then you should just look for that feature and disable it. Some mobos have a physical switch and I think you have that. Check your user's guide and take a look at this thread: http://www.tomshardware.co.uk/forum/306359-28-intel-core-2500k-asus-p8z68-disable-overclocking

Prahsper · Jan 28, 2015

VicVega1 :

Thanks for your help. However, nothing I have tried has worked. PC still won't boot up with all four dimms installed. Even with OC turned off. I don't think this board can take2 1333's and 2 1600's at the same time. I will just upgrade to 2x8gb 1600's. Thanks again for your assistance.

Tradesman1 · Jan 28, 2015

With the 1333 sticks only in try raising the DRAM voltage + 0.06, set the freq and timings for the 1333 sticks manually and raise the CPUVTT to 1.14 and try

Vic 40 · Jan 28, 2015

Tried a clear cmos first too when going to optimal default settings?
For this take the motherboard battery of the motherboard for about 15min,seems long but to make sure in this case,and put it back afterwards,after that set the bios to the optimal default settings and see if the bclk is at 100 and overclock is gone.
You haven't used some software in windows to overclock?

Prahsper · Jan 29, 2015

Vic 40 :

No...no software was used for overclocking. This board comes pre-overclock set with auto-overclock feature for those unfamiliar with setting up overclock.
I did all stated above. Nothing work so far.
I did manage to find out how to turn off overclock completely.
My TPU switch was set for enable (don't know how that happened.) I turn that off.
AI overclock tuner to 'auto"
Turbo ratio=auto
Internal PLL overvoltage=disabled
Mem frequency=ddr3-1333mhz
EPU power saving=disabled
OC tuner=cancel
DRAM timing=(didn't know what to do there. Left it alone)
CPU power management=Turbo mode=disabled
When this was all done BCLK/PCIE=100
Some of these option don't show unless AI OC tuner is in 'manual'. After all was set, I put it back to 'auto'
Put bios back to optimal default setting...rebooted...finish bootup...then shut down.
Restarted and check setting in bios to see if all stuck. Yes all settings stayed the way I set them and OC is off.
Shutdown again....added the new memory....PC still beeps once...comes on....then 2 seconds later shuts off....and this continues unless I shut the power switch off and pull the power cord.
Don't know what else to do.
"Tradesman1" stated: [With the 1333 sticks only in try raising the DRAM voltage + 0.06, set the freq and timings for the 1333 sticks manually and raise the CPUVTT to 1.14 and try]
LOL....he lost me there! Didn't even see a CPUVTT in my bios. My DRAM voltage is at 1.50v

VicVega1 · Jan 29, 2015

Prahsper :

It's what you written in the first post:

CAS# 9.0 clocks
RAS to CAS# 9 blocks
RAS# Precharge 9 blocks
Cycle time 24 blocks

try typing those manually

Have you cleared the CMOS?

Prahsper :

CPU VTT goes by many names depending on the mobo manufacturer, but basically that's the voltage for the Integrated Memory Controller. It may be called IMC, QPI/VTT, QPI/DRAM. Not all mobos give you the ability to tweak that, but I think your ASUS should.

Vic 40 · Jan 29, 2015

Prahsper :

I think that in your case the cpu/vtt is called vccio.Just try raising it one notch at a time and see if it helps.

Prahsper · Jan 29, 2015

Vic 40 :

OK....I tried everything all of you have suggested. Did as you explained. CMOS battery out for 20min. Optimal default set again. TPU switch is off. When I place all four dimms in, I get the same old on & off-on & off nonsense still. I placed them differently each time just to see.
As is:
1333 1600 1333 1600
1333 1333 1600 1600
1600 1600 1333 1333
I took more pictures of the bios for you guys to take a close look at. After I take the 1600's out and PC boots up, I get the screen you see in the first image. "Overclocking Failed"
I know I did all the manual states at turning off this OC mess. I can't see what I am missing or why this board keeps trying to OC everything. The images show what the bios reverts to after rebooting.

Please take a close look at the new images listed here: http://imgur.com/a/8UjHj

VCCIO to 1.12 or so

Prahsper · Feb 1, 2015

Tradesman1 :

OK...nothing some to work. So I have given up on trying to get these 2 sets of mixed memory to work together. I am just going to get 2 more of what I know I do have.
I would still like to thank you all for you assistance, advice and recommendations.

Now, according to the program CPU-Z my memory is:
Crucial Ballistix Sport 4GB DDR3 1333mhz PC3-10700h

I can't seem to find the exact one numbered the same. So will
Crucial Ballistix Sport 4GB DDR3 1333mhz pc3-12800 work with my originals or is this considered mixed memory as well?
If it is considered mixed also then I will just get 4x4GB DDR3 1333MHZ PC3-12800's

Tradesman1 · Feb 1, 2015

Yep, any time you mix sticks from different packages it's a crapshoot - even the same exact model

VicVega1 · Feb 2, 2015

Prahsper :

too bad it didn't work out.
but hold on, you're mixing stuff up.
your current memory is PC3-10700 (which is actually 10666, most often listed as 10600)
PC3-12800 is not 1333MHz, it's 1600MHz.
Best way would be to get one stick out and check the exact model number on it and using that number to determine if you're looking at the same model when buying. Example from my RAM sticks: CML16GX3M4A1600C9B
Or getting a complete new set of how many gigs you'd like to have.

Tradesman1 :

Motherboards are so picky nowadays. A couple of years back you could mix almost anything if it fitted the slot

Well maybe more than just a couple of years..

Ahh...so I see now. So my model number of my original 1333's is BLS4G3D1339DS1S00.
So you're saying if I can find 2X2GB 1333MHZ PC3-1066 (for instance) sticks with this same model number, then they will work together?
Is that what i am doing wrong here?

1333mhz with 1600mhz Memory. Will It Work?
