memory speed problem

grishagreg · Mar 30, 2014

HI all,my bios shown me only 1600mhz but my memory stick can run at 1866mhz without oc and my mobo accepted ram with speed 2133mhz after oc so 1866mhz should be fine but they are won't run with that speed.Please help.Thanks

Have you changed the speed in the BIOS/UEFI to run the ram at the 1866 speed. That is where it needs to be done.

Hi,first thanks to try help me but in bios have maximum 1600mhz

1866 it's not shown at list??

What mobo, CPU and DRAM (the model #)

grishagreg · Mar 30, 2014

Mobo is msi 990xa-gd55
amd phenon 2 x4 965 3.4ghz quad core am3+
g.skill ddr3 1866 cl10-11-10-30 1.50v dual channel 2x8gb

grishagreg · Mar 30, 2014

ram f3-14900 cl10D-16gbxl

bgunner · Mar 30, 2014

the reason is because the CPU's memory controller only supports the 1600 and nothing higher. sorry but you will not reach that frequency. I have the same CPU.

grishagreg · Mar 30, 2014

So to reach 1866mhz i need change my procossor??

bgunner · Mar 30, 2014

correct. to an FX series CPU.

what about this one will be good??

Tradesman1 · Mar 30, 2014

Yep, the 965 was the first AMD CPU that could effectively run 1600, some can hit 1866 but it takes some manipulation and voltage increases, if you want to try

1. CPU Host Frequency will need to be 233 for DDR3-1866 (may want to lower the CPU multiplier as this will OC the CPU also)
2. CPU-NB Frequency should be 2800MHz
3. Raise DRAM voltage to 1.6
4. Set CPU/NB voltage to about 1.3

Thanks for that but early today i already tried put cpu at 220 and then black screen only and nothing happend so get the battery out and back to 200 but will try put all changes as you said.Thanks anyway and please tell me if my mobo will be fine with taht cpu

that cpu is not on that motherboards CPU list so i would be cautious on buying that one with out talking to MSI first. That CPU has a very high TDP of 220W and needs to have a AIO water cooling solution, many times sold in the same package, to cool it. The highest that is on the CPU list is the FX 8350.

@ Tradesman: I will give this a try for the heck of it just to see if my CPU can handle it. If not then no loss as I'm already pushing the top limits of this CPU anyways.

grishagreg · Mar 30, 2014

Thanks so http://www.aria.co.uk/Products/Components/Processors/AMD+CPUs/FX+%28Piledriver%29+-+Socket+AM3%2B/AMD+%28Piledriver%29+FX-8350+4.00GHz+%284.20GHz+Turbo%29+Socket+AM3%2B+8-Core+Processor+-+Retail+?productId=52722 this one will run with my mobo and also my ram will run at 1866 yes??

bgunner · Mar 30, 2014

Yes you are correct that the FX-8350 will work on your motherboard for sure and run the 1866 MHz ram with out issues. Like i said though if you want to use that first one you will need to contact MSI to be sure it is supported. Just a simple Email will work.

Thank you all for help

)))))))))))))))) and i have large cooler zalman cnps12x so should be fine.Thanks again guys

bgunner · Mar 30, 2014

your welcome and have fun.

grishagreg · Mar 30, 2014

Tradesman1 :

Just to let you know oc has failed.Thanks once again and i will wait till get some money for cpu.

Tradesman1 · Mar 30, 2014

8350 is a good choice and can run 1866 sticks (and just for info, it's basically as powerful as the 9590 without all the extra voltage and heat), also for cooling can look at a CM Hyper 212 EVO (about $35) which will do the job well, think you'd be happy with all

grishagreg · Mar 31, 2014

Thanks for more info and i will go for 8350 but last week just spend money for new cooler check it out:

I didn't buy from them but just to gave you some info about cooler,so do you think this one is no good enough????evo will be better choice or i can saty with my.Thanks again Greg.
