OCZ Blade ST 1600Mhz doesn't want to oc :(

post #1 of 9
Thread Starter 
Hello after having some problems with my previous ram kit, I'm currently overclocking my new config:
Gigabyte 790XTA-UD4
AMD Phenom II X4 955 Be C2
OCZ Blade ST 12800 DDR3 1.65V

I successfully oc my 955 at 16*244=3904Mhz 1.5V and NB-CPU 2684Mhz at 1.325V WITH ram desynchro to 5.33 to begin.
The fact is, I wanted to know ram limits with 6.66 desynchro: It is supposed to be run at
7-8-8-24/1600Mhz/1.65V
Okay, before any overclock (CPU,NB etc.) the only way to be stable was to put the CPU-NB voltage at 1.3V
Now with the HT 244:
244*6.66=1625Mhz
I'm NOT even prime blend stable at 8-9-8-26-2T
tRC 35, tRFC 160ns
Here are my timings:



Any ideas, advices ?
I saw a topic where a guy had the same ram and at 1.71V ram voltage but at 6-7-6-21/1600Mhz so I thought oc would be easy..
Am I making a mistake ?

Increase the CPU-NB voltage somewhat more, you are overclocking that too you know, that might be unstable

No, look at cpu spec, I played with the multi to get stock settings aiming to target only ram stability, I kept my cpu nbvid at 1.325V anyway without the nbvid oc

edit: Oh, and I tried to increase a little ram voltage 1.71V does not change anything

You were stable at 7-8-8-26 before but now can't do it on x6.66 multiplier
It may be an unstable memory multiplier @ that ref clock; it happens
You don't need to OC the ref clock anyway with a black edition processor

Well, I prefer hiting 3.9Ghz at 244*16 than 200*19.5
First, because I need less vcore to achieve this (don't know why) and it gives me 2684Mhz=11*244 CPU-NB stable.
Indeed at 200*19.5, CPU-NB is stable at 2600Mhz=13*200 but clearly not at 14*200=2800Mhz.


According to you what is the good choice ?
1) 244*11=3.9Ghz CPU, 2684Mhz CPU-NB, ram at loosened timings but above 1600Mhz
2) 244*11=3.9Ghz CPU, 2684Mhz CPU-NB, ram at tightened timings but desynchro at 1333Mhz
3) 200*19=3.9Ghz CPU, 2600Mhz CPU-NB, ram at stock timings and 1600Mhz

The fact is that I'm sure that 3.9Ghz CPU is not my limit so even at 200*19, I will try 201*19, 202*19 at the very end and the problem will be the same with my ram, it will increase respectively 1600,1608,1616.

The sacrifice here seems rather odd... how much less vCore do you need at 244x11 vs 200 x19.5?

thare is a point why ocz doped out of making ram. I never could get them to run right. allthe times where unstable and 1 stick would be bad. also change the setting in bios not in software holds better results

1.525 for 200*19.5
1.500 for 244*11

Don't think it is the only reason. The fact is that chips are not their own and they are making much more benefits with their good SSD.

Wow, that's not a huge difference... and the 790XTA-UD4 would be more than capable of that
I say go for it at 200Mhz.
