Can i put 2 dual channel sticks of ram along with the single one i have ?

oldplod · Dec 24, 2016

So I have 4 gb of ram on my pc [a single stick of 4 gb 1333 mhz - (Silicon Power - sp004gbltu133v02)] and I found a very good deal on 2 sticks of dual channel Ram 2x2Gb at 1600 mhz (Corsair XMS3 ) . Can I add the sticks to my pc and make them work together ? I know they will probably work at 1333 mhz if i`m not wrong , but will they actually work ?
My MTB is a ASUS P7H55-M PRO .
Waiting for a response . Thank you
By the way my mtb has 4 slots for ram . I run a i3 540 first gen with a gtx 650 OC version 1 Gb along with Windows 7 x64 and a 500 gb HDD .

Yes, it will work. The only thing you would have to do is put the two new RAM sticks in the 1st and 3rd RAM slots, and put the old stick in the 2nd slot. As for the memory frequency, you will probably have to disable XMP profiling, and set the RAM to run only at 1333 Mhz.

Can't say for sure. Try it.
Mixing different ram modules is game of luck. It may require manual tweaking of ram settings in BIOS.
Even if you manage them to work together, it will still revert to single channel mode.

Mixing modules is his and miss , even identical modules purchased at separate times can be incompatible. You won't know till you try them.

I will pick them up tomorrow and try them out . Does it affect performance if it will run in single channel instead of dual channel ? Btw I checked with my mtb`s supported ram and it`s in the list .

oldplod :

Of course it affects performance. All memory operations will be significantly slower.
But in everyday computing it's not that noticeable (unless you run some memory benchmarks). Sufficient amount of ram is far more important than speed of it.

If it works it'll be in flex mode. Double sticks in dual and one in single. Even if it was all in single, there are only a few software that would have less performance. Your only real concern is if it works and is stable.

BuckyJunior · Dec 24, 2016

All I can say is to try it. There isn't really any way to tell if it will work.

Ok , so I bought another stick of ram instead of the kit I wanted to buy . It`s a Kingmax flff65f-d8kq9 . It`s 4gb , 1333 Mhz . Now when i try to run both of them my pc freezes at the bios screen and it doesn`t get past that . I only tried allternating them in the blue slots of my motherboard , i think that`s first and third slot . Can someone tell me what i can do to make them work ? Didn`t try anything yet because i don`t want to ruin it . The new stick works . I know this because i took it of a working pc . Sorry for the bad english

Does the system work, when you install new module alone?
Post screenshots from CPU-Z memory and spd section when system is booted with one module at a time.

It doesn't work with the new stick alone . i get a bsod with BAD_POOL_HEADER . I notice that the timing in bios was set to auto and was 9-9-9-24 . And i think this ram is 9-9-9-27 . iVe set that mannualy and nothing . But now i'm wondering if something else is wrong too . btw does it matter that this new stick is single-sided while the old one is double sided ?
And i noticed that the auto timing for my old ram is set to 7-7-7-20 for some reason ...

SkyNetRising · Dec 30, 2016

I'd like to see CPU-Z memory, spd screenshots when you boot with old ram module.

After that install new module alone and set memory timings to 10-10-10-30.
Try to boot into windows and get same CPU-Z screenshots for new module.

Here are the screenshots for the old ram :

I tried forcing 10-10-10-30 timing for the new ram only to get a IRQL_NOT_LESS_OR_EQUAL BSOD . Then i tried forcing 7-7-7-24 and that made the pc to give no image to the monitor untill i cleared cmos.

oldplod · Dec 31, 2016

Should I try to force some other timing ? I found online that the kingmax has the timing 9-9-9-27 while i couldn`t find exactly what timing the silicon power has except for 9-9-9 . Should i try to increase the voltage ? They both should run at 1.5v ... I tried disabling xmp profiling , forcing to run at 1333 mhz altough they do . Now the motherboard detects the ram in bios (only the new one ) but i can`t get past the bios screen without a bsod ( depends on what i do ) , and can`t even make it to run in safe mode . Maybe it`s just the motherboard that`s a bit of an a**hole .. I wanted to buy the same stick that i had buut can`t find it nowhere . And as i`m currently unemployed i didn`t have money to get a new kit or something .
LE: Sorry for the double post . I just realised i didn`t update my last answer ... But the only difference i see in bios when it comes to timing is that the old one is 9-9-9-24-108 (on auto) and the new one is 9-9-9-24-200 ( on auto altough i found out online that it`s 9-9-9-27)
Any ideas ?

Higher timings mean higher compatibility, but lower performance.
Stick with 10-10-10-30,rest on auto and try lowering frequency: 1333 -> 1066 -> 800.
Also try putting ram module in different slots.

If every attempt fails, then it's possible that new ram module is just incompatible with your motherboard.
