OC voltage and such...

post #1 of 10
Thread Starter 
So, I have a 1090T on an MSI 890FXA-GD70 board and G.Skill Sniper 2x4gb 9-9-9-24 2t RAM. (SIG RIG)I am having some stability problems when I make almost any changes to my FSB reference. I would like to increase my HT speeds. so far I am stable at 4.0ghz with 2.6ghz on the NB. that is without adjusting the FSB reference. I think it is my ram that is faulting out. But I cannot do anything with my ram it seems without DA II crashing (thats the one I have been playing) after 5 or so minutes. Here is my current setup:

CPU: 200x20 @ 4.0ghz; 1.48v
NB: 200x13 @ 2.6ghz; 1.3v
RAM: 9-9-9-24 2T; 1.5v (all stock settings)

I really wanna hit 4.2ghz with HT at 3.0ghz any thoughts? Is 1.52 volts safe to run my CPU at for a 24/7 OC? how about RAM at 1.7v? All replies and suggestions welcome!! TIA!

This OC seems rather fine already.
I'd leave things like that and not risk with any more volts.
Just drop the timings to, say, 7-7-7-20 and enjoy

EDIT: Never OC HT. It works fastest at 2000, anything beyond leads to drop in performance..

If I drop my timings, will I have to adjust my voltages or DRAM speed? On that note, where can I find a memory benchmark? Or does such a thing exist?

Yes, its called MaxxMEM2, free downloadable. No, you won't need to lower DRAM freq in order to lower timings.

OK, Ill give it a shot. Hopefully I can stay stable. seems like every time I mess with my RAM my system hard locks about 5 minutes into any game I am playing, but will stay fine on the desktop all day... I'll bring the NB back to 2.0ghz.

The NB? No, wait

NB and HT are different things. NB is good as high as stable, HT is good at 2000

Thats normal, Phenom II does not support 1600Mhz RAM. Only OCed 1333. So even if you had it running at 1600, it was actually 1333.

Don't expect to drop your timings and it just works. Overclocking RAM does not work that way. Drop each timing one at a time. You may need to use extra RAM voltage too. That particular kit, it would probably OC no further than 7-9-7 if it does at all.

ronnin, you're also wrong about Phenom II not supporting 1600Mhz RAM. There's an x8 multiplier for running 1600Mhz RAM. It may not be actually officially supported by AMD, but it's there, and on the x6 CPU, it should run with no problem even on 4 DIMMs.

I understand that OC'ing RAM is done in steps. But I have been finding it quite difficult to get tighter timings out of them that are stable. However I just did this:

CPU: 250x16 (4.0ghz) @1.45v
NB: 250x12 (3.0ghz) @1.32v
RAM: 9-9-9-24 2T and 1600mhz @1.6v
HT in CPU-Z reads 2500mhz (Should I adjust down?)

MaxxMEM went from 11,512 read with NB at 2.0ghz to over 15k with NB at 3.0ghz.
CPU-Z does read the RAM at 800mhz dual so I think it does support 1600mhz

Prime95 still BSOD (BCC Code 50)after a few minutes.
HW Monitor reads CPU Cores at 50c (safe or no?)

Thanx all for your help thus far!

From what I gather BSODs are memory problems whereas hard-locks are CPU issues. Is this almost always the case when it comes to OC?
