GA-870A-UD3 and F3-10666CL7D-8GBECO

[Pszaij]

Hi,
My motherboard is GA-870A-UD3 rev 3.0 and CPU is Phenom II X4 955 BE.

Is F3-10666CL7D-8GBECO compatible with this Motherboard?
If I use four sticks, what memory voltage should I set to get a stable system?

Thanks!

This is a two stick set, so with 4 sticks you're talking two sets, which I don't really recommend, there's no guarantee the sets will place nice. That being said, I'd suggest a single 4 stick set, but if you want to try, with your mobo and CPU (and the latest BIOS, I think they'll prob play together OK but will prob have to add a little voltage to the DRAM (say up to 1.4) and will have to raise the CPU/NB for the simple fact that you'll have 4 sticks

this works on my motherboard?
but if I buy 4 sticks, to need to raise the voltage?

This set should work, may have to raise the CPU/NB a bit but should be fine

[Pszaij]

okay, so I'll try this sticks..
how to set CPU/NB? I looked in the manual of my motherboard but do not think.

Tranks Again! (:

May be called CPU NB VID or something like that

[Pszaij]

How much do I have to increase voltage,
To be able to leave the memory running stable? That's what I do not know!
CPU NB VID.

[Tradesman]

Try starting with + .1 then if thats good can decrease it while maintaining stability , maybe .01 at a time, or if not stable add + .05 to DRAM voltage and let me know what happens

okay, tranks! (:

Let us know how it goes

Hi, I bought memory F3-10666CL7Q-16GBXH, but I don't know set CAS# 7-7-7-21.

DCTs Mode = Unganged
CAS Latency = 7 (manual)
RAS to CAS R/W Delay = 7 (manual)
Row Precharge Time = 7 (manual)
Minimum RAS Active Time = 21(manual)
1T/2T Command Timing = 2T
TwTr Command Delay = 5T
Trfc0 for DIMM1 = 160ns
Trfc2 for DIMM2 = 160ns
Trfc1 for DIMM3 = 160ns
Trfc3 for DIMM4 = 160ns
Write Recovery Time = 10T
Precharge Time = 5T
Row Cycle Time = 33T
RAS to RAS Delay = 7T
Bank Interleaving = Enabled
Channel Interleave = Enabled

Looks good, any problem with it?

[Pszaij]

No problem with it. functioning very well!
These are settings, all correct.
