[SOLVED] Identifying ddr3 modules with fake spd data

[VulcanxD]

Hi guys, i bought recently 2 sticks of ddr3, seller claimed to be 4gb 1866 each.
Upon inspection this modules can't even get 1600 without locking up.
First module utilizes 16 chips of samsung made K4B2G0446C-HCF8, so 8 in each side of the stick.
Second module still same desing uses K4B2G0446C-HYH9 chips.
Since the spd data are clearly manipulated how can i identify capacity and frequency ?
Thanks in advance

 

[kerberos_20]

K4B2G0446C-HCF8 1333MHz CL9 1.5V
K4B2G0446C-HYH9 1033MHZ CL7 1.35V

those are base chips, not overclocked and both of them shouldnt be compatible with eachother

they may come sold as overclocked version with included XMP profile
how do you know spd data are manipulated?

What is your CPU and motherboard model? You may just be limited by your CPU and motherboard.

Yeap thanks, bought them from aliexpress as 1866mhz 4gb for 15euros that's how i know 😛 They cant operate at 1866 nor 1600. Still they work fine at 1333mhz without errors. They dont have xmp
From the datasheets HCF8 is cl7 1.5v 1033mhz and HYH9 cl9 1.35v 1333mhz
I'm not so sure about the capacity since my knowledge is limited to undestand just by the specs.
I'll grab some cpuz images both sticks come with the same spd data

capacity u get from counting chips together
both are 2Gbit, u said each stick has 16? 16x2 = 32Gbit /8 = 4GB
as for speed, stick no3,4 are recently produced, its not like they are brand new, its just reused old chips so for those dunno if chinese did some binning proccess or just glued some scrap parts together and called it a day

btw your mainboard and cpu can support 4 sticks at 1866MHz?
mainboard will need 6 layers and T topology for those speeds

btw your mixed rams are in wrong slots, same sticks should be on same channel, switch stick from slot 2 to slot 3

Thanks for the advice so capacity is correct, just the chips are old and repurposed, since they can't even achieve the speeds advertised.
Yeah my mobo supports 1866
thanks

edit: My mobo is a88xm-a, changing slots will result in no post...
Slots are color coded ...

Unless the manual says otherwise, it's usually best to install 2 different kits in a staggered manner and in slots A2/B2 first with two modules only. So say you wanted to run 4 modules at 1333mhz, but one of the kits is 1600Mhz and the other is 1333 or just run different cas latency with the same speed. Depending on what the manual says or if it's an Intel system, you would place the 1333Mhz modules in slots A2/B2 and 1600Mhz in slots A1/B1 so all 4 run at 1333mhz with the same timings hopefully taken from the 1333 kit. It usually doesn't matter what slots the modules go into as long as they are staggered. If you look over your screen shot of RAMMon, you have the 1866Mhz kits in slots 1 and 2 and the 1777Mhz kit in slots 3 and 4. You should take the module in slot 3 (B1) and move it to slot 2 (A2) and move slot 2 to slot 3. |CPU Socket| |A1|A2|B1|B2|

Just did that, pc won't post ... A1+A2 installed the 1866kit B1+B2 installed the chinese knock off it wont post... Tried the other way around still no post...
It only posts like u explained in the beggining and i have to manually set them to 1333

Ok well, to be honest, I think the issue is just the 1777Mhz memory being terrible. I would personally try to get a second Kingston Hyper X Fury 1866 cl10 kit and just keep the 1777Mhz kit as backup.

Yeap their not even real 1777mhz they cant go past 1600 without errors. Thanks for the help
