Struggling to get 2400mhz memory stable

post #1 of 3
Thread Starter 
Hi there

I have ADATA 16gb (2x8GB) DDR3 2400mhz 11-13-13-35 kit but can't get it to run at 2400mhz without my pc freezing or anything like that Here is my pc specs:

corsair ax850w
GTX980ti
4790k
h100i
Asus vii ranger z97
ADATA 16gb (2x8GB) DDR3 2400mhz 11-13-13-35
PG279q


What I do is I first tested my overclocks by setting the memory at 1600mhz 1.5V all stock settings but after that I enable xmp and can't get it stable. Here is my bios settings so far and readings via HWinfo


Cpu multiplier: 47x
CPU voltage: 1.250v
Cache ratio: 40x
Cache voltage: 1.15V
Dram voltage: 1.65V
CPU digital io offset: +0.050v reads 1.07V
CPU analog io offset: +0.050V reads 1.07V
CPU input voltage: 1.88V reads 1.88V
System agent voltage: +0.150 reads 0.984 as highest volts

I can't get my memory stable on xmp profile and also tried with everything stock volts except for cpu and cache voltage and still doesn't work.

So I've been thinking will a lower cpu core clock actually help me a lot getting my xmp to work. I won't mind running at 4.6GHz but getting xmp as I can really feel the difference in performance/smoothness when I play games for a little while before it freezes my system. I think memory gives me better minimum FPS but whatever it is it just feels smoother.

The problem I get is my games will random times just freeze and having to hard reset my system.

Use stock CPU settings with RAM XMP. Don't OC the CPU, if the RAM can't run that and the UEFI did adjust Vsa, ioa, iod accordingly for the XMP then that kit is bad IMHO.

Sorry forgot to add. I already tried stock and it works just fine. I had everything on stock with stock volts and enabled xmp and it worked for a few days or so. I know it might be a weak IMC but don't know if the kit could also be the fault and it doesn't like my 4.6ghz overclock.

According to aida64 the Dram:FSB ratio is 36:3 on xmp profile so don't know if it's good. I can do the following 1866mhz 11-11-11-32 CR2 abd it runs fine but would like to run 2400mhz and I don't have a another kit to test.

What I did so far is by clocking my cpu to 4.6ghz same settings and voltages but setting my memory on xmp profile to test and see if it works now. I've been reading up about analog/digital io voltages and byt setting a offset I can maybe get my ram more stable. When I first had my cpu overclocked to 4.7ghz I had that on stock and would get crashes much sooner and decided to do some research and then I heard about analog/digital io voltage and increased it slightly and was a lot more stable than before but still crashes. So Now I'm thinking if I clock my cpu at 4.6ghz and then run xmp if that won't help a bit. I know the best way to see if it works is if I just set my cpu to 4.6ghz, enable xmp and see for myself but maybe I can increase some other voltages a bit or maybe there's a way to find out if my memory is the culprit.

so far 4.6GHz xmp profile my aida 64 score is the following

Read: 35822
Write: 37588
Copy: 34861
Latnecy: 48.6ns

at 1866mhz 11-11-11-32 CR2 the following results

Read: 27295
Write: 29136
Copy: 26894
Latency: 59.8ns


Also the following I noticed when setting xmp vs 1866 11-11-11-32 cr2

L2 cache: 3.4ns vs 3.3ns
l3 cache: 12.3ns vs 10.6ns

So I even win some latency on L3 and L2 cache.


Edit: So far played bf4 for most of the day today and it works fine so far on the following settings

Cpu multiplier: 46x
CPU voltage: 1.250v
Cache ratio: 40x
Cache voltage: 1.15V
Dram voltage: 1.65V
CPU digital io offset: +0.050v reads 1.07V
CPU analog io offset: +0.050V reads 1.07V
CPU input voltage: 1.88V reads 1.88V
System agent voltage: +0.150 reads 0.984 as highest volts

The game feels even smoother than on 47x for some reason. Maybe the cpu is not 100% stable on 47x that's why it doesn't feel as smooth
